The general objective was to determine the epidemiological aspects of obesity, overweight and associated risk factors in a semi-urban environment. Patients and Methods: This was a cross-sectional, descriptive study conducted on November 28 and 29, 2023 in Sébikotane. It focused on volunteers for screening for chronic non-communicable diseases. Epidemiological and clinical data were evaluated. Results: One hundred and twenty-nine cases of obesity were recorded (28%). Two hundred and eighty-two cases were overweight or obese (61.3%). The mean age was 49.55 years, with a standard deviation of 12.41 years. The age group [40 - 49 years] was the most representative, with 85 cases (30.1%), and the majority were female, with 264 cases (93.6%). Primary education was the most common, with 75 cases (46.3%). Grade 1 obesity concerned ninety-seven cases (75.2%), and diabetes was present in thirty cases (23%). Hypertension was present in ninety-five cases (33.7%). Obesity was more marked in the age group [40 - 49 years] with 45 cases (36%). Conclusion: Obesity and overweight are a major cause of morbidity and mortality. The development and implementation of a prevention and management program is essential.展开更多

In countri...Context: Antiretroviral therapy (ART) helps restore the health status of people living with HIV (PLHIV). Likewise, it increases the risk of overweight/obesity and related comorbidities among the recipients. In countries like Botswana where ±84% of PLHIV is on ART, the paucity of data comparing overweight/obesity between HIV-positive on ART and HIV-negative patients may impede clinical and policy decision-making. This study sought to estimate and compare: i) the prevalence of overweight/obesity between HIV-positive on ART and HIV-negative patients;ii) the prevalence of hypertension (HTN), diabetes mellitus (DM)/coronary heart disease (CHD) between HIV-positive patients on ART and HIV-negative patients attending same outpatient departments of general clinics in Gaborone, Botswana. Patients and Methods: Five hundred eighty-one (581) outpatients were recruited in four major clinics of Gaborone, Botswana, between June and July 2019;294 or 51% of them were HIV-negative and 287 or 49% were HIV-positive on ART. The prevalence of overweight/obesity and of HTN and DM/CHD were calculated and examined using stratified analysis. Subgroups were compared using Chi-square analysis with Yates correction or Fisher exact test and t-student test for continuous data. Results: Major findings after stratification of the study population by HIV status were: i) the prevalence of all categories of (BMI), including overweight/obesity, were comparable between HIV-negative-patients and HIV-positive. In fact, there were 24 (8.0%) cases of underweight among HIV-negative-Patients and 15(5%) cases among HIV-positive patients, p = 0.2;145 (49%) HIV-negative-patients and 128 (45%) HIV-positive, p = 0.07 cases of normal weight;72 (25%) HIV-negative-patients and 87 (30%) HIV-positive, p = 0.08, were overweight;53 (18%) HIV-negative-patients and 57 (20%) HIV-positive, p = 0.12, were obese;125 (43%) HIV-negative patients and 144 (50%) HIV-positive, p=0.06 were overweight/obese;ii) the prevalence of HTN and DM/CHD among HIV-positive-patients were significantly lower (p < 0.05) compared to HIV-negative patients: There were 32 (10.9%) cases of HTN among HIV-negative patients compared to 18 (6.3%) cases of HTN among HIV-positive patients, p = 0.001;32 (11%) cases of DM/CHD HIV-negative patients compared to 4 (1.4%) cases of DM/CHD among HIV-positive patients, p = 0.001. Conclusion: the prevalence of overweight/obesity observed between HIV-negative and HIV-positive patients may suggest that the two groups shared the same exposure factors. That HTN and DM/CHD prevalence was lower among HIV-positive compared to HIV-negative patients, is possibly due to interplay factors of ART, HIV or the host population. Further studies are, however, recommended for clarifications.展开更多

This is a cross-sectional survey with 697 university students from northern and central Mexico (448 women, and 249 men aged 18 - 19 years). Data was collected during 2018. Overweight and obesity were calculated from those indices and for both, female and male students, the order of correlation between a pair of indices were WHtR vs. RFM > WHtR vs. WC > RFM vs. WC > WHtR vs. BMI > BMI vs. WC > RFM vs. BMI. It is concluded to use the WHtR and the RFM to better predict overweight and obesity in young Mexican university students.展开更多

Methods Data sets of boys and girls at the age of 7-18 years collected from the series of Chinese national surveillance on students＇ constitution and health （CNSSCH） between 1985 and 2000 were divided into five socioeconomic and demographic groups, while BMI classification reference proposed by Working Group on Obesity in China （WGOC） was used as screening reference to calculate the prevalence and trends of overweight/obesity in these groups. Results In 2000, the prevalence of obesity and overweight in boys aged 7-18 years was 11.3% and 6.5% in Beijing, 13.2% and 4.9% in Shanghai, 9.9% and 4.5% in coastal big cities, and 5.8% and 2.0% in coastal medium/small-sized cities, respectively, while the prevalence of of obesity and overweight in girls of the same age group was 8.2% and 3.7% in Beijing, 7.3% and 2.6% in Shanghai, 5.9% and 2.8% in coastal big cities, and 4.8% and 1.7% in coastal medium/small-sized cities, respectively. The prevalence of obesity was low in most of the inland cities at an early stage of epidemic overweight. The epidemic manifested a gradient distribution in groups, which was closely related to status （SES） of the study population. However, a dramatic and steady increasing trend was witnessed among all sex-age subgroups in the five urban groups, and such a trend was stronger in boys than in girls, and much stronger in children than in adolescents. Conclusion Although China is at an early stage of epidemic obesity by and large, the prevalence of obesity in her urban population, particularly in coastal big cities has reached the average level of developed countries. The increasing trend has been rapid since early 1990s, and the increments in obesity and overweight are exceptionally high. The prospect of epidemic obesity in China is in no way optimistic. Therefore, preventive program should be focused on the improvement of the balance between caloric intake and energy expenditure, and interventions aimed at changing children＇s life styles.展开更多

Methods 2000 CNSSCH （Chinese National Survey on Students Constitution and Health） data, including 216 620 primary and secondary school students aged 7 to 18 years old, were used as a reference population. Compared with those of the NCHS intematioanl reference, three temporary sets of cut-off BMI were proposed by testing different combinations of P85, P90, and P95. When physiological and biochemical measures between and among “obesity” “overweight”, and “normal weight” groups were taken into consideration, set Ⅱ was selected to be the most appropriate one. The sex-age-specific curves were then plotted and smoothed by using B-spline method. Results Based on the samples from costal developed metropolis, the BMI curves successfully overcame the shortcomings of lower and level-off tendency of the Chinese total population. Temporary set H, composed by cut-offs of P85 for overweight and P95 for obesity, was finally selected by its sensitivity and peculiarity. BMI 24 and 28 were used as cut-offs for overweight and obesity for both males and females aged 18 years old. These cut-offs, consistent with Chinese Adult＇s Reference, was proposed as the Body mass index reference for screening overweight and obesity in Chinese school-age children and adolescents. Conehlsion The new reference clearly showed its superiorty in both prospectivity and actuality. The proposed reference minimized the gaps of the BMI curve between Chinese adolescents and the international reference. Most importantly was that it was consistent with the Eastern Asia ethnic characteristics of body fatness growth. It was therefore proposed by the Working Group on Obesity in China （WGOC） to use it as an nationwide reference for screening overweight and obesity of school-age children and adolescents in China.展开更多

The Student's t-test, x2 test and multivariate logistic regression analysis were utilized to evaluate the relationship between IHD and salient risk factors.RESULTS: The all-over prevalence of overweight was 41.4%, and that of fatty liver was 29.5% (mild, moderate and severe fatty liver being 14.5%, 11.3%, and 3.7%,respectively); while the prevalence of ischemic changes on ECG was 17.1% in this study. The abnormal rates for conventional IHD risk factors including hypertension,dyslipidemia, hyperglycemia and overweight increased in accordance with the severity of fatty liver. Overweight and severity of fatty liver were independently associated with increased risks for developing IHD. Overweight subjects had a 1.32-fold (95%CI: 1.01-1.73) increased IHD risk. Participants with mild, moderate, and severe fatty liver had a 1.88-fold (95%CI: 1.37-2.6), 2.37-fold (95%CI: 1.66-3.37) and 2.76-fold (95%CI: 1.62-4.72)increased risk for developing IHD. The prevalence of ischemic ECG for the fatty liver-affected subjects with or without overweight was 30.1% and 19.1%, while that of overweight subjects free from fatty liver was 14.4%.Compared to the subjects without fatty liver nor overweight,IHD risk for the three subgroups above was as follows:OR: 2.95 (95%CI:2.31-4.09), OR: 1.60 (95%CI: 1.07-2.39)and OR: 1.11 (95%CI: 0.78-1.56), respectively.CONCLUSION: The presence of fatty liver and its severity should be carefully considered as independent risk factors for IHD. Results of the study suggest the synergistic effect between fatty liver and overweight for developing IHD.Abdominal sonographic examination may provide valuable information for IHD risk assessment in addition to limited report about liver status, especially for overweight males.展开更多

The subjects were divided by the body mass indexes （BMI） into the normal weight group （n=397, BMI〈24 kg/m2） and the overweight group （n=400, BMI〉24 kg/m2）. Our results showed that the overweight group had higher blood pressure [（130.15±19.01） mmHg vs （123.66±18.70） mmHg] and higher levels of blood sugar [（7.09±2.89） mmol/L vs （6.21±2.59） mmol/L], triglyceride [（1.93±1.19） mmol/L vs （1.44 ±0.85） mmol/L], total cholesterol [（4.26±1.06） mmol/L vs （4.09±0.99） mmol/L], low-density lipoprotein cholesterol （LDL-C） [（2.56±0.75） mmol/L vs （2.39±0.72） mmol/L], and apoB [（0.83±0.27） mg/L vs （0.78±0.23） mg/L], and a higher apoB/apoA1 ratio （0.83 ±0.27 vs 0.75±0.25） and lower levels high-density lipoprotein cholesterol [（1.10±0.26） mmol/L vs （1.21±0.31） mmol/L] and apoA1 [（1.04±0.20） mg/L vs （1.08±0.22） mg/L] than those of the normal weight group （all P 〈 0.05）. The prevalence of CHD in the over-weight group in the lowest LDL quartile was almost twice greater than that of the highest apoB/apoA1 quartile, compared with the subjects in the lowest apoB/apoA1 quartile. The higher apoB/apoA1 quartile was in agreement with the higher prevalence of CHD. In the overweight and obesity group, the area under ROC curve （AUC） was the highest for apoB/apoA1 （0.655）. The cut-off point of apoB/apoA1 for optimal sensitivity and specificity was at 0.80, with a sensitivity of 57.19% and a specificity of 71.72%. In conclusion, apoB and apoA1 were simple clinical indicators, and the apoB/apoA1 ratio was closely related with CHD in overweight and obese patients. The apoB/apoA1 ratio may provide some useful information in the differential diagnosis.展开更多

Methods This cross-sectional study was carried out as part of students physical fitness and health survey in Jiangsu province. A total of 255,581 subjects （50.03% males and 49.97% females） enrolled in 82 school and 10 universities in Jiangsu. Weights and heights were obtained for each subject and its body mass index （BMI） was calculated using the Chinese Working Group on Obesity in China （CWGO）. Results Anthropometric measurement including bodyweight, height, BMI and bust were significantly different between males in urban compared to females living rural areas （P〈0.001）. The total prevalence of overweight and obesity was 12.4% and 5.7%. Males had a significantly higher rate than in female＇s student. The prevalence of overweight and obesity by age groups was （14.5%, 10.3%） at age 7-11 years, （11.2%, 6.8%） at age 12-14 years, （11.7%, 3.1%） at age 15-17 years, and （11.4%, 2.3%） at age 18-22 years. By regions; the highest prevalence of overweight obesity reported in Taizhou （10.0%, 14.2%）, Xuzhou （9.4%, 12.5%）, and Nanjing （9.2%, 15.6%）, respectively. Conclusion The finding declares that overweight and obesity are important health problems among students in Jiangsu Province. Early intervention programme are needed to address this problems.展开更多

METHODS: A total of 196 consecutive patients (103 females, age range 18-83 years) with symptoms of gastro-esophageal reflux (GER) and 24-h pathological esophageal pH-metry. Body mass index (BMI) of the patients was calculated and its distribution (%) was compared with that of the Italian general population as assessed by National Bureau of Census (ISTAT). To evaluate the association of GERD with weight categories, the binomial test was employed. P < 0.05 was considered statistically significant. RESULTS: In males, overweightedness (BMI 25-25.9) was present in 43% of GERD patients vs 41.8% of Italian population (IP) (ns), obesity (BMI ≥ 30) in 10.9% vs 9.1% (ns). In females overweight was present in 34.9% of GERD patients vs 25.7% of IP (P < 0.01), obesity in 13.6% of GERD patients vs 9.1% of IP (P < 0.01). No statistically significant differences were noted in different age classes. CONCLUSION: In comparison to the Italian general population, the prevalence of overweightedness and obesity is increased in female but not in male patients with ascertained gastro-esophageal reflux disease.展开更多

METHODS: Comprehensive electronic searches of the PubMed, Web of Science, and Cochrane Library databases were conducted. Studies were identified that included patients with surgical complications from gastric cancer who were classified as normal weight [body mass index (BMI) < 25 kg/m 2 ] or overweight (BMI ≥ 25 kg/m 2 ). The operative time, retrieved lymph nodes, blood loss, and long-term survival were analyzed. A subgroup analysis was conducted based on whether patients received laparoscopic or open gastrectomy procedures. All statistical tests were performed using ReviewerManager 5.1.2 software. RESULTS: This meta-analysis included 23 studies with 20678 patients (15781 with BMI < 25 kg/m 2 ; 4897 with BMI ≥ 25 kg/m 2 ). Overweight patients had significantly increased operation times [MD: -29.14; 95%CI: -38.14-(-20.21); P < 0.00001], blood loss [MD: -194.58; 95%CI: -314.21-(-74.95); P = 0.001], complications (RR: 0.75; 95%CI: 0.66-0.85; P < 0.00001), anastomosis leakages (RR: 0.59; 95%CI: 0.42-0.82; P = 0.002), and pancreatic fistulas (RR: 0.486; 95%CI: 0.34-0.63; P < 0.00001), whereas lymph node retrieval was decreased significantly in the overweight group (MD: 1.69; 95%CI: 0.75-2.62; P < 0.0001). In addition, overweight patients had poorer long-term survival (RR: 1.14; 95%CI: 1.07-1.20; P < 0.0001). No significant difference was detected for the mortality and length of hospital stay. CONCLUSION: This meta-analysis demonstrates that a high BMI not only increases the surgical difficulty and complications but also impairs the long-term survival of patients with gastric cancer.展开更多

METHODS： Circulating levels of Bcl-2 were detected in 84 patients with ultrasonographic findings of ＂bright liver＂ and/or hyper-transaminasemia of unknown origin and/or increase in T-glutamyl-transpeptidase （T-GT） strictly in the absence of other acute or chronic liver disease, whose age was not advanced, who gave consent to liver biopsy and were then divided on the basis of the histological results into two groups （43 with FL and 41 with NASH）. Twenty lean subjects, apparently healthy and young, were chosen as controls.RESULTS： Serum Bcl-2 concentrations were significantly higher in the FL group than in the NASH group. Insulin resistance and γ-GT activity were significantly higher in NASH subjects. Apoptotic hepatocytes were significantly more numerous in NASH patients. NASH patients presented with larger spleens and augmented C-reactive protein （CRP） concentrations than healthy subjects. Steatosis grade at histology was similar in both NASH and FL populations. The number of apoptotic cells was significantly related to anti-apoptotic Bcl-2 protein values in FL patients. Bcl-2 serum levels positively correlated to body mass index （BMI） values （P ~ 0.0001） but not to age of the population. Triglycerides/HDL ratio correlated well to waist circumference in males （P = 0.0008）. γ-GT activity was associated with homeostatic metabolic assessment （HOMA） （P = 0.0003） and with serum ferritin （P = 0.02）. Bcl-2 concentrations were not related to either spleen size or CRP values. NASH patients pre- sented a weak negative correlation between Iobular inflammation and Bcl-2 levels. A prediction by low values of serum Bcl-2 towards a greater presence of metabolically unhealthy overweight/obese patients （MUOs） was evidenced. HOMA, BMI and uric acid, in that sequence, best predicted serum Bcl-2 concentrations. CONCLUSION： IvlUOs could be detected by Bcl-2 levels. By favoring the life span of hepatocytes, and enhancing triglyceride formation, the anti-apoptotic process inhibits free fatty acids toxicity in FL.展开更多

Methods Eighty-five overweight and obese children （OOC）, and eighty-five age-matched healthy children （HC） were recruited in this case-control study. The present study analyzed spectrophotometrically vitamin C （VC）, vitamin E （VE）, and β-carotene （β-CAR） in plasma, as well as the activities of superoxide dismutase （SOD）, catalase （CAT）, and the level of malondialdehyde （MDA） in erythrocytes. Results Compared with those of VC, VE, β-CAR, SOD, CAT and MDA in the HC group, the average values of VC, VE, β-CAR, SOD, and CAT in the OOC group were significantly decreased （P〈0.001）, while the average value of MDA in the OOC group was significantly increased （P〈0.001）. The regression analysis demonstrated that VC, VE, β-CAR, SOD, and CAT were negatively correlated （P〈0.05-0.01）, and MDA was positively correlated with BMI （P〈0.05）. Fitting to the model of multiple stepwise regression of BMI on VC, VE, β-CAR, SOD, CAT, and MDA in 85 OOC was Y = 27.0041 ＋ 0,2541MDA - 2.1448β-CAR -- 0.0090CAr, where F = 43.8088, P〈0.001, r = 0.7866, r^2= 0.6187, adjusted r^2= 0.6046. The findings from the reliability analysis for VC, VE, β-CAR, SOD, CAT, and MDA used to reflect increased oxidative stress and potential oxidative damage in the OOC showed that the reliability coefficients （alpha, 6 items） = 0.7231, P〈0.0001, and that the standardized item alpha = 0.9207, P〈0.0001, Conclusion The present study suggests that there exists an increased oxidative stress in overweight and obese children.展开更多

By using income as a budget constraint and signal for future wellbeing in a life-course utility model, we examine the association amongst income and overweight. The data used for this study are from the China Health and Nutrition Survey(CHNS). Estimations are conducted for overweight initiation, cessation, and participation mirroring a decision to begin and a past decision to not terminate. Our findings propose that body weight and the likelihood of overweight commencement rise with additional income but at a diminishing degree, representing a concave relation;while the likelihood of overweight discontinuance declines with additional income but at an accelerating degree, suggesting a convex relation.We presume that, as opposed to developed countries, low-income people are less inclined to be overweight in China, a country in transition. This could be explained by an income constraint for unhealthy foodstuff. Nevertheless, it will switch when income surpasses the critical threshold of the concave or inverted U-shape curve indicating that low-income people appear to receive not as much utility from future health. Specifically, this adjustment seems to occur earlier for females and inhabitants of urban areas.展开更多

文摘Prenatal overweight/obesity(OW/OB)can alter colostrum lipid patterns,thereby affecting the lipid metabolism and even the cognitive and healthy development of infants.However,studies on changes in colostrum lipids in the context of OW/OB are limited,particularly for glycerides and polar lipids.Therefore,this study investigated the infl uence of maternal prenatal weight on colostrum in lipid subclasses and molecular species.The concentration of triacylglycerols(TAGs)in the colostrum of the OW/OB group(35894.43 mg/L)was higher than that of the normal weight(NW)group(26639.20 mg/L),suggesting that colostrum from OW/OB mothers could provide more energy to their infants.Further analysis of the fatty acid composition of TAGs revealed that elevated maternal body weight enhanced the concentration of TAGs containing saturated or n-6 fatty acids and shortened the carbon number of TAGs.Docosahexaenoic acid(DHA)/arachidonic acid(AA)/choline-containing lipids,such as DHA-containing TAGs,AA/DHA-containing phosphatidylethanolamine,and choline-containing phospholipids,were present in higher levels in the colostrum of OW/OB mothers than NW mothers.However,the concentrations of palmitic acid-containing TAGs,linoleic acid-containing TAGs,dihomo-γ-linolenic acid-containing TAGs,and polar lipids and the ratio of TAGs containing n-6 fatty acid/n-3 fatty acid were signifi cantly higher in the colostrum of OW/OB mothers than in that of NW mothers.The fatty acid composition and sphingoid bases of sphingolipids were also altered due to elevated body weight.In conclusion,OW/OB affects colostrum lipids with respect to composition,concentration,and percentage.Although the colostrum of healthy OW/OB mothers can provide suffi cient DHA/AA/choline-containing lipids to their infants,normalization of body weight and fat reserves should be considered as a strategy for highquality human milk lipids.
文摘Introduction: Obesity and overweight are a public health problem. The general objective was to determine the epidemiological aspects of obesity, overweight and associated risk factors in a semi-urban environment. Patients and Methods: This was a cross-sectional, descriptive study conducted on November 28 and 29, 2023 in Sébikotane. It focused on volunteers for screening for chronic non-communicable diseases. Epidemiological and clinical data were evaluated. Results: One hundred and twenty-nine cases of obesity were recorded (28%). Two hundred and eighty-two cases were overweight or obese (61.3%). The mean age was 49.55 years, with a standard deviation of 12.41 years. The age group [40 - 49 years] was the most representative, with 85 cases (30.1%), and the majority were female, with 264 cases (93.6%). Primary education was the most common, with 75 cases (46.3%). Grade 1 obesity concerned ninety-seven cases (75.2%), and diabetes was present in thirty cases (23%). Hypertension was present in ninety-five cases (33.7%). Obesity was more marked in the age group [40 - 49 years] with 45 cases (36%). Conclusion: Obesity and overweight are a major cause of morbidity and mortality. The development and implementation of a prevention and management program is essential.

文摘BACKGROUND Overweight/obesity combined with depression among children and adolescents(ODCA)is a global concern.The bidirectional relationship between depression and overweight/obesity often leads to their comorbidity.Childhood and adolescence represent critical periods for physical and psychological development,during which the comorbidity of overweight/obesity and depression may increase the risk of adverse health outcomes.AIM To evaluate the relationship between ODCA,we conduct a bibliometric analysis to aid in formulating prevention and treatment strategies.METHODS From 2004 to 2023,articles related to ODCA were selected using the Science Citation Index Expanded from the Web of Science Core Collection.Bibliometric analysis of relevant publications,including countries/regions,institutions,authors,journals,references,and keywords,was conducted using the online bibliometric analysis platforms,CiteSpace,VOSviewer,and bibliometrix.RESULTS Between 2004 and 2023,a total of 1573 articles were published on ODCA.The United States has made leading contributions in this field,with Harvard University emerging as the leading contributor in terms of research output,and Tanofsky being the most prolific author.The J Adolescent Health has shown significant activity in this domain.Based on the results of the keyword and reference analyses,inequality,adverse childhood experiences,and comorbidities have become hot topics in ODCA.Moreover,the impact of balancedrelated behavior and exploration of the biological mechanisms,including the potential role of key adipocytokines and lipokines,as well as inflammation in ODCA,have emerged as frontier topics.CONCLUSION The trend of a significant increase in ODCA publications is expected to continue.The research findings will contribute to elucidating the pathogenic mechanisms of ODCA and its prevention and treatment.
文摘Context: Antiretroviral therapy (ART) helps restore the health status of people living with HIV (PLHIV). Likewise, it increases the risk of overweight/obesity and related comorbidities among the recipients. In countries like Botswana where ±84% of PLHIV is on ART, the paucity of data comparing overweight/obesity between HIV-positive on ART and HIV-negative patients may impede clinical and policy decision-making. This study sought to estimate and compare: i) the prevalence of overweight/obesity between HIV-positive on ART and HIV-negative patients;ii) the prevalence of hypertension (HTN), diabetes mellitus (DM)/coronary heart disease (CHD) between HIV-positive patients on ART and HIV-negative patients attending same outpatient departments of general clinics in Gaborone, Botswana. Patients and Methods: Five hundred eighty-one (581) outpatients were recruited in four major clinics of Gaborone, Botswana, between June and July 2019;294 or 51% of them were HIV-negative and 287 or 49% were HIV-positive on ART. The prevalence of overweight/obesity and of HTN and DM/CHD were calculated and examined using stratified analysis. Subgroups were compared using Chi-square analysis with Yates correction or Fisher exact test and t-student test for continuous data. Results: Major findings after stratification of the study population by HIV status were: i) the prevalence of all categories of (BMI), including overweight/obesity, were comparable between HIV-negative-patients and HIV-positive. In fact, there were 24 (8.0%) cases of underweight among HIV-negative-Patients and 15(5%) cases among HIV-positive patients, p = 0.2;145 (49%) HIV-negative-patients and 128 (45%) HIV-positive, p = 0.07 cases of normal weight;72 (25%) HIV-negative-patients and 87 (30%) HIV-positive, p = 0.08, were overweight;53 (18%) HIV-negative-patients and 57 (20%) HIV-positive, p = 0.12, were obese;125 (43%) HIV-negative patients and 144 (50%) HIV-positive, p=0.06 were overweight/obese;ii) the prevalence of HTN and DM/CHD among HIV-positive-patients were significantly lower (p < 0.05) compared to HIV-negative patients: There were 32 (10.9%) cases of HTN among HIV-negative patients compared to 18 (6.3%) cases of HTN among HIV-positive patients, p = 0.001;32 (11%) cases of DM/CHD HIV-negative patients compared to 4 (1.4%) cases of DM/CHD among HIV-positive patients, p = 0.001. Conclusion: the prevalence of overweight/obesity observed between HIV-negative and HIV-positive patients may suggest that the two groups shared the same exposure factors. That HTN and DM/CHD prevalence was lower among HIV-positive compared to HIV-negative patients, is possibly due to interplay factors of ART, HIV or the host population. Further studies are, however, recommended for clarifications.
文摘The goal was to compare body mass index (BMI), waist circumference (WC), waist to height ratio (WHtR), and relative fat mas (RFM), to identify the best predictor of overweight and obesity in university students from Mexico. This is a cross-sectional survey with 697 university students from northern and central Mexico (448 women, and 249 men aged 18 - 19 years). Data was collected during 2018. Overweight and obesity were calculated from those indices and for both, female and male students, the order of correlation between a pair of indices were WHtR vs. RFM > WHtR vs. WC > RFM vs. WC > WHtR vs. BMI > BMI vs. WC > RFM vs. BMI. It is concluded to use the WHtR and the RFM to better predict overweight and obesity in young Mexican university students.
文摘Introduction: The problem of excess weight is pandemic and affects the majority of nations, regardless of their level of development. However, the prevalence of overweight among workers in Benin is very poorly documented. To fill this gap, the present study aimed to determine the prevalence and factors associated with overweight among workers of the Ministry of Labor and Public Service (MTFP) in 2023 in Benin. Materials and Methods: This is a descriptive cross-sectional study with analytical purposes carried out from August 16 to December 17, 2023, among MINISTRY OF LABOR AND PUBLIC SERVICE staff. The variables studied were overweight, sociodemographic, occupational and dietary characteristics, lifestyle, anthropometric factors and family history of obesity. An exhaustive recruitment of workers meeting our inclusion criteria and a questionnaire survey was carried out. Data were analyzed using R 4.0.4 software. A bivariate analysis followed by a multivariable analysis made it possible to identify the factors associated with overweight at the p Results: In total, 379 workers were included in our study. The average age of the surveyed workers was 44.86 years ± 7.67 years, with 202 (53.30%) workers at least 45 years old. Men predominated with a number of 228 (60.16%). The prevalence of overweight was 63.32% (95% CI: [58.23 - 68.15]) and the associated factors after multivariate analysis were: female sex (ORa = 4.00;95% CI [2.11 - 7.76];p Conclusion: The prevalence of overweight is high among ministry of labor and public service workers. Education and awareness in the professional environment on the prevention and management of risk factors are essential for a long-term impact on a notable regression of this public health phenomenon.
文摘To investigate the relationship between food insecurity(FI)and overweight/obesity(OW/OB)or corresponding chronic diseases in adolescents,33 studies with 181135 individuals were included in this meta-analysis.Six studies and 10 studies,reported a higher risk of overweight and obesity in adolescents experiencing FI,respectively(OR 1.38,95%CI 1.20‒1.58,P<0.0001;OR 1.11,95%CI 1.01‒1.22,P=0.035,respectively).Based on the pooled results,adolescents with severe FI had the highest risk of OW/OB(OR 1.45,95%CI 1.20‒1.75,P<0.0001).The pooled OR indicated no signifi cant association between FI and OW/OB,when the adolescents were stratifi ed into those under 6 years old and those between 6 and 18 years old.Eleven studies assessed the relationship between FI and the risk of chronic diseases.The anemia subgroup was significantly associated with FI(OR 1.67,95%CI 1.30‒2.13,P<0.0001).Severe FI was reported to increase the risk of hypertension(OR 1.59,95%CI 1.28‒1.98,P<0.0001).Furthermore,a pooled analysis revealed a signifi cant association between FI and the risk of chronic diseases in both 6 and 6-18-year-old subgroups.

文摘Objective To describe the nationwide prevalence of childhood overweight/obesity, and their group variations and trends over the past 20 years in the Chinese urban population. Methods Data sets of boys and girls at the age of 7-18 years collected from the series of Chinese national surveillance on students＇ constitution and health （CNSSCH） between 1985 and 2000 were divided into five socioeconomic and demographic groups, while BMI classification reference proposed by Working Group on Obesity in China （WGOC） was used as screening reference to calculate the prevalence and trends of overweight/obesity in these groups. Results In 2000, the prevalence of obesity and overweight in boys aged 7-18 years was 11.3% and 6.5% in Beijing, 13.2% and 4.9% in Shanghai, 9.9% and 4.5% in coastal big cities, and 5.8% and 2.0% in coastal medium/small-sized cities, respectively, while the prevalence of of obesity and overweight in girls of the same age group was 8.2% and 3.7% in Beijing, 7.3% and 2.6% in Shanghai, 5.9% and 2.8% in coastal big cities, and 4.8% and 1.7% in coastal medium/small-sized cities, respectively. The prevalence of obesity was low in most of the inland cities at an early stage of epidemic overweight. The epidemic manifested a gradient distribution in groups, which was closely related to status （SES） of the study population. However, a dramatic and steady increasing trend was witnessed among all sex-age subgroups in the five urban groups, and such a trend was stronger in boys than in girls, and much stronger in children than in adolescents. Conclusion Although China is at an early stage of epidemic obesity by and large, the prevalence of obesity in her urban population, particularly in coastal big cities has reached the average level of developed countries. The increasing trend has been rapid since early 1990s, and the increments in obesity and overweight are exceptionally high. The prospect of epidemic obesity in China is in no way optimistic. Therefore, preventive program should be focused on the improvement of the balance between caloric intake and energy expenditure, and interventions aimed at changing children＇s life styles.

文摘Purpose To establish and propose a national body mass index （BMI） reference for screening overweight and obesity in Chinese school-age children and adolescents. Methods 2000 CNSSCH （Chinese National Survey on Students Constitution and Health） data, including 216 620 primary and secondary school students aged 7 to 18 years old, were used as a reference population. Compared with those of the NCHS intematioanl reference, three temporary sets of cut-off BMI were proposed by testing different combinations of P85, P90, and P95. When physiological and biochemical measures between and among “obesity” “overweight”, and “normal weight” groups were taken into consideration, set Ⅱ was selected to be the most appropriate one. The sex-age-specific curves were then plotted and smoothed by using B-spline method. Results Based on the samples from costal developed metropolis, the BMI curves successfully overcame the shortcomings of lower and level-off tendency of the Chinese total population. Temporary set H, composed by cut-offs of P85 for overweight and P95 for obesity, was finally selected by its sensitivity and peculiarity. BMI 24 and 28 were used as cut-offs for overweight and obesity for both males and females aged 18 years old. These cut-offs, consistent with Chinese Adult＇s Reference, was proposed as the Body mass index reference for screening overweight and obesity in Chinese school-age children and adolescents. Conehlsion The new reference clearly showed its superiorty in both prospectivity and actuality. The proposed reference minimized the gaps of the BMI curve between Chinese adolescents and the international reference. Most importantly was that it was consistent with the Eastern Asia ethnic characteristics of body fatness growth. It was therefore proposed by the Working Group on Obesity in China （WGOC） to use it as an nationwide reference for screening overweight and obesity of school-age children and adolescents in China.

文摘Objective To evaluate trends of overweight and obesity prevalence between 1996 and 2007 in Yi farmers and Yi migrants.Methods An Yi migrant study was conducted in Liangshan Yi Autonomous Prefecture,Sichuan Province,China from 1996 to 2007.Data were collected with identical methods,including standardized questionnaire and body measurements.Results Age‐ and sex‐specific body mass index （BMI） significantly increased from 20.02 in 1996 to 22.36 in 2007,among Yi farmers,which was significantly different from those among Yi migrants （23.67 in 2007 and 20.90 in 1996） （P0.05）.Prevalence of obesity rose from 1.21 % in 1996 to 4.55 % in 2007 （OR=1.15,P0.001） in Yi migrants,while that in Yi farmers from none in 1996 to 0.12 % in 2007 （P0.05）.Prevalence of overweight rose significantly to 26.24 %in 2007 from 17.24 % in 1996 （OR=1.06,P0.001） in Yi migrants,while that in Yi farmers from 1.29 % in 1996 to 4.45 % in 2007 （OR=1.14,P0.001）.Yi migrants appeared to have a 5.52‐fold higher risk ondeveloping overweight and obesity than Yi farmers have.Conclusion The Yi migrants had a steeper increase of overweight with year and consequently caused more obesity.Change in lifestyle may contribute most likely to higher prevalence of overweight and obesity in Yi migrants.
文摘AIM: To demonstrate the prevalence of sonographic fatty liver, overweight and ischemic heart disease (IHD) among the male workers in Taiwan, and to investigate the possible association of these three factors.METHODS: From July to September 2003, a total of 2 088 male aircraft-maintenance workers aged from 22to 65 years (mean 40.5) underwent an annual health examination, including anthropometrical evaluation, blood pressure measurement, personal medical history assessment,biochemical blood analysis, abdominal ultrasonographic examination and digital electrocardiography (ECG). The Student's t-test, x2 test and multivariate logistic regression analysis were utilized to evaluate the relationship between IHD and salient risk factors.RESULTS: The all-over prevalence of overweight was 41.4%, and that of fatty liver was 29.5% (mild, moderate and severe fatty liver being 14.5%, 11.3%, and 3.7%,respectively); while the prevalence of ischemic changes on ECG was 17.1% in this study. The abnormal rates for conventional IHD risk factors including hypertension,dyslipidemia, hyperglycemia and overweight increased in accordance with the severity of fatty liver. Overweight and severity of fatty liver were independently associated with increased risks for developing IHD. Overweight subjects had a 1.32-fold (95%CI: 1.01-1.73) increased IHD risk. Participants with mild, moderate, and severe fatty liver had a 1.88-fold (95%CI: 1.37-2.6), 2.37-fold (95%CI: 1.66-3.37) and 2.76-fold (95%CI: 1.62-4.72)increased risk for developing IHD. The prevalence of ischemic ECG for the fatty liver-affected subjects with or without overweight was 30.1% and 19.1%, while that of overweight subjects free from fatty liver was 14.4%.Compared to the subjects without fatty liver nor overweight,IHD risk for the three subgroups above was as follows:OR: 2.95 (95%CI:2.31-4.09), OR: 1.60 (95%CI: 1.07-2.39)and OR: 1.11 (95%CI: 0.78-1.56), respectively.CONCLUSION: The presence of fatty liver and its severity should be carefully considered as independent risk factors for IHD. Results of the study suggest the synergistic effect between fatty liver and overweight for developing IHD.Abdominal sonographic examination may provide valuable information for IHD risk assessment in addition to limited report about liver status, especially for overweight males.

文摘We investigated the relationship of apoB/apoA1 ratio and coronary heart disease （CHD） in persons who were overweight or obese. The subjects were divided by the body mass indexes （BMI） into the normal weight group （n=397, BMI〈24 kg/m2） and the overweight group （n=400, BMI〉24 kg/m2）. Our results showed that the overweight group had higher blood pressure [（130.15±19.01） mmHg vs （123.66±18.70） mmHg] and higher levels of blood sugar [（7.09±2.89） mmol/L vs （6.21±2.59） mmol/L], triglyceride [（1.93±1.19） mmol/L vs （1.44 ±0.85） mmol/L], total cholesterol [（4.26±1.06） mmol/L vs （4.09±0.99） mmol/L], low-density lipoprotein cholesterol （LDL-C） [（2.56±0.75） mmol/L vs （2.39±0.72） mmol/L], and apoB [（0.83±0.27） mg/L vs （0.78±0.23） mg/L], and a higher apoB/apoA1 ratio （0.83 ±0.27 vs 0.75±0.25） and lower levels high-density lipoprotein cholesterol [（1.10±0.26） mmol/L vs （1.21±0.31） mmol/L] and apoA1 [（1.04±0.20） mg/L vs （1.08±0.22） mg/L] than those of the normal weight group （all P 〈 0.05）. The prevalence of CHD in the over-weight group in the lowest LDL quartile was almost twice greater than that of the highest apoB/apoA1 quartile, compared with the subjects in the lowest apoB/apoA1 quartile. The higher apoB/apoA1 quartile was in agreement with the higher prevalence of CHD. In the overweight and obesity group, the area under ROC curve （AUC） was the highest for apoB/apoA1 （0.655）. The cut-off point of apoB/apoA1 for optimal sensitivity and specificity was at 0.80, with a sensitivity of 57.19% and a specificity of 71.72%. In conclusion, apoB and apoA1 were simple clinical indicators, and the apoB/apoA1 ratio was closely related with CHD in overweight and obese patients. The apoB/apoA1 ratio may provide some useful information in the differential diagnosis.

文摘Objective To report the prevalence and trend of overweight and obesity among students aged 7-22 years in Jiangsu, 2010 to 2013. Methods This cross-sectional study was carried out as part of students physical fitness and health survey in Jiangsu province. A total of 255,581 subjects （50.03% males and 49.97% females） enrolled in 82 school and 10 universities in Jiangsu. Weights and heights were obtained for each subject and its body mass index （BMI） was calculated using the Chinese Working Group on Obesity in China （CWGO）. Results Anthropometric measurement including bodyweight, height, BMI and bust were significantly different between males in urban compared to females living rural areas （P〈0.001）. The total prevalence of overweight and obesity was 12.4% and 5.7%. Males had a significantly higher rate than in female＇s student. The prevalence of overweight and obesity by age groups was （14.5%, 10.3%） at age 7-11 years, （11.2%, 6.8%） at age 12-14 years, （11.7%, 3.1%） at age 15-17 years, and （11.4%, 2.3%） at age 18-22 years. By regions; the highest prevalence of overweight obesity reported in Taizhou （10.0%, 14.2%）, Xuzhou （9.4%, 12.5%）, and Nanjing （9.2%, 15.6%）, respectively. Conclusion The finding declares that overweight and obesity are important health problems among students in Jiangsu Province. Early intervention programme are needed to address this problems.
文摘AIM: To evaluate whether the prevalence of overweight and obese conditions is increased in gastro-esophageal reflux disease (GERD) patients (with 24-h pathological pH recordings) in comparison to general population. METHODS: A total of 196 consecutive patients (103 females, age range 18-83 years) with symptoms of gastro-esophageal reflux (GER) and 24-h pathological esophageal pH-metry. Body mass index (BMI) of the patients was calculated and its distribution (%) was compared with that of the Italian general population as assessed by National Bureau of Census (ISTAT). To evaluate the association of GERD with weight categories, the binomial test was employed. P < 0.05 was considered statistically significant. RESULTS: In males, overweightedness (BMI 25-25.9) was present in 43% of GERD patients vs 41.8% of Italian population (IP) (ns), obesity (BMI ≥ 30) in 10.9% vs 9.1% (ns). In females overweight was present in 34.9% of GERD patients vs 25.7% of IP (P < 0.01), obesity in 13.6% of GERD patients vs 9.1% of IP (P < 0.01). No statistically significant differences were noted in different age classes. CONCLUSION: In comparison to the Italian general population, the prevalence of overweightedness and obesity is increased in female but not in male patients with ascertained gastro-esophageal reflux disease.
文摘AIM: To investigate the effect of being overweight on the surgical results of patients with gastric cancer. METHODS: Comprehensive electronic searches of the PubMed, Web of Science, and Cochrane Library databases were conducted. Studies were identified that included patients with surgical complications from gastric cancer who were classified as normal weight [body mass index (BMI) < 25 kg/m 2 ] or overweight (BMI ≥ 25 kg/m 2 ). The operative time, retrieved lymph nodes, blood loss, and long-term survival were analyzed. A subgroup analysis was conducted based on whether patients received laparoscopic or open gastrectomy procedures. All statistical tests were performed using ReviewerManager 5.1.2 software. RESULTS: This meta-analysis included 23 studies with 20678 patients (15781 with BMI < 25 kg/m 2 ; 4897 with BMI ≥ 25 kg/m 2 ). Overweight patients had significantly increased operation times [MD: -29.14; 95%CI: -38.14-(-20.21); P < 0.00001], blood loss [MD: -194.58; 95%CI: -314.21-(-74.95); P = 0.001], complications (RR: 0.75; 95%CI: 0.66-0.85; P < 0.00001), anastomosis leakages (RR: 0.59; 95%CI: 0.42-0.82; P = 0.002), and pancreatic fistulas (RR: 0.486; 95%CI: 0.34-0.63; P < 0.00001), whereas lymph node retrieval was decreased significantly in the overweight group (MD: 1.69; 95%CI: 0.75-2.62; P < 0.0001). In addition, overweight patients had poorer long-term survival (RR: 1.14; 95%CI: 1.07-1.20; P < 0.0001). No significant difference was detected for the mortality and length of hospital stay. CONCLUSION: This meta-analysis demonstrates that a high BMI not only increases the surgical difficulty and complications but also impairs the long-term survival of patients with gastric cancer.
文摘AIM： To shed some light on the relationship between anti-apoptotic serum Bcl-2 concentrations and metabolic status, anthropometric parameters, inflammation indi- ces, and non-alcoholic fatty liver disease severity were investigated in 43 young individuals with fatty liver （FL） and 41 with nonalcoholic steatohepatitis （NASH）. METHODS： Circulating levels of Bcl-2 were detected in 84 patients with ultrasonographic findings of ＂bright liver＂ and/or hyper-transaminasemia of unknown origin and/or increase in T-glutamyl-transpeptidase （T-GT） strictly in the absence of other acute or chronic liver disease, whose age was not advanced, who gave consent to liver biopsy and were then divided on the basis of the histological results into two groups （43 with FL and 41 with NASH）. Twenty lean subjects, apparently healthy and young, were chosen as controls.RESULTS： Serum Bcl-2 concentrations were significantly higher in the FL group than in the NASH group. Insulin resistance and γ-GT activity were significantly higher in NASH subjects. Apoptotic hepatocytes were significantly more numerous in NASH patients. NASH patients presented with larger spleens and augmented C-reactive protein （CRP） concentrations than healthy subjects. Steatosis grade at histology was similar in both NASH and FL populations. The number of apoptotic cells was significantly related to anti-apoptotic Bcl-2 protein values in FL patients. Bcl-2 serum levels positively correlated to body mass index （BMI） values （P ~ 0.0001） but not to age of the population. Triglycerides/HDL ratio correlated well to waist circumference in males （P = 0.0008）. γ-GT activity was associated with homeostatic metabolic assessment （HOMA） （P = 0.0003） and with serum ferritin （P = 0.02）. Bcl-2 concentrations were not related to either spleen size or CRP values. NASH patients pre- sented a weak negative correlation between Iobular inflammation and Bcl-2 levels. A prediction by low values of serum Bcl-2 towards a greater presence of metabolically unhealthy overweight/obese patients （MUOs） was evidenced. HOMA, BMI and uric acid, in that sequence, best predicted serum Bcl-2 concentrations. CONCLUSION： IvlUOs could be detected by Bcl-2 levels. By favoring the life span of hepatocytes, and enhancing triglyceride formation, the anti-apoptotic process inhibits free fatty acids toxicity in FL.
文摘Objective To investigate whether overweight and obesity might cause oxidative stress and potential oxidative damage in overweight and obese children, and to explore its possible mechanism. Methods Eighty-five overweight and obese children （OOC）, and eighty-five age-matched healthy children （HC） were recruited in this case-control study. The present study analyzed spectrophotometrically vitamin C （VC）, vitamin E （VE）, and β-carotene （β-CAR） in plasma, as well as the activities of superoxide dismutase （SOD）, catalase （CAT）, and the level of malondialdehyde （MDA） in erythrocytes. Results Compared with those of VC, VE, β-CAR, SOD, CAT and MDA in the HC group, the average values of VC, VE, β-CAR, SOD, and CAT in the OOC group were significantly decreased （P〈0.001）, while the average value of MDA in the OOC group was significantly increased （P〈0.001）. The regression analysis demonstrated that VC, VE, β-CAR, SOD, and CAT were negatively correlated （P〈0.05-0.01）, and MDA was positively correlated with BMI （P〈0.05）. Fitting to the model of multiple stepwise regression of BMI on VC, VE, β-CAR, SOD, CAT, and MDA in 85 OOC was Y = 27.0041 ＋ 0,2541MDA - 2.1448β-CAR -- 0.0090CAr, where F = 43.8088, P〈0.001, r = 0.7866, r^2= 0.6187, adjusted r^2= 0.6046. The findings from the reliability analysis for VC, VE, β-CAR, SOD, CAT, and MDA used to reflect increased oxidative stress and potential oxidative damage in the OOC showed that the reliability coefficients （alpha, 6 items） = 0.7231, P〈0.0001, and that the standardized item alpha = 0.9207, P〈0.0001, Conclusion The present study suggests that there exists an increased oxidative stress in overweight and obese children.

文摘Previous literature has demonstrated that low-income people are more likely to settle for poor health choices in developed countries. By using income as a budget constraint and signal for future wellbeing in a life-course utility model, we examine the association amongst income and overweight. The data used for this study are from the China Health and Nutrition Survey(CHNS). Estimations are conducted for overweight initiation, cessation, and participation mirroring a decision to begin and a past decision to not terminate. Our findings propose that body weight and the likelihood of overweight commencement rise with additional income but at a diminishing degree, representing a concave relation;while the likelihood of overweight discontinuance declines with additional income but at an accelerating degree, suggesting a convex relation.We presume that, as opposed to developed countries, low-income people are less inclined to be overweight in China, a country in transition. This could be explained by an income constraint for unhealthy foodstuff. Nevertheless, it will switch when income surpasses the critical threshold of the concave or inverted U-shape curve indicating that low-income people appear to receive not as much utility from future health. Specifically, this adjustment seems to occur earlier for females and inhabitants of urban areas.
