It is a concept that considers not only food quantity but also food quality. The objective of this study was to describe dietary diversity and food security status at the individual level in Cameroonian populations. Methods: A total of 1180 men and women aged 20 and over and living in the West, North West, and Littoral regions of Cameroon were recruited. Data on dietary habits were collected through the frequency of consumption of various food groups. Dietary diversity was assessed using a 24-hour dietary recall. Food security status was determined by combining two indicators (food consumption score and individual food diversity score). Results: The mean dietary diversity score of the population was 3.53 ± 1.44, p Conclusion: The diet diversity of adults living in the West, North West, and Littoral regions of Cameroon is medium. Although half of the study population was food secure, there is a need to implement food security policies further to reduce food insecurity among the Cameroonian population.展开更多

This study aimed to describe lifestyle habits and dietary diversity among medical students. Methodology: This was a cross-sectional, descriptive study, carried out at the UFR 2S of the University Gaston Berger from May 23 to June 3, 2023. The collection tool focused on sociodemographic characteristics, lifestyle habits and dietary diversity. Statistical analyzes were carried out using R software. Results: A total of 471 students participated in this study. Which corresponds to a participation rate of 89.2% with a M/F sex ratio of 1.66. The age of participants, varying from 18 to 32 years, had a median of 23 years and a mean of 22.4 years with a standard deviation of 2.2 years. Among the participants, 67.2% skipped breakfast, and 28.5% did not practice any physical sports activity. Alcohol and tobacco were consumed by 2.5% and 0.6% of participants, respectively. The most consumed foods were starchy foods (97.5% of men and 98.4% of women);and the least consumed were dark green leafy vegetables (21.9% of men and 15.1% of women) and offal (16.9% of men and 11.9% of women). The dietary diversity score was low for 31.9% of men and 28.7% of women. Conclusion: Certain lifestyle habits (skipping breakfast, dining late at night, lack of sports practice) of Medicine students at UGB can prove deleterious to their well-being. These students are at risk of developing several deficiencies in terms of food groups that are underrepresented in their diet. Awareness sessions on good lifestyle habits and diet would be relevant recommendations for improving the health of these students.展开更多

The review examined the policy environment in sub-Saharan Africa in relation to linkages between agricultural diversification, dietary diversity, and nutrition. The systematic review of literature entailed searching Ovid MEDLINE, PubMed, Embase, African Journals Online and PsychINFO databases from Jan 1, 2010, to Feb 30, 2021, for eligible studies and technical reports. Publications reporting on agricultural diversification, dietary diversity, and nutrition outcomes in relation to policy environment were included. Qualitative synthesis of the abstracted evidence was conducted. SSA countries recognise the crucial role of agricultural diversification as a pathway to achieving food security with increasing emphasis on smallholder farmers. There is a rich base of policies that are complemented by lived experiences and best practices which can strengthen linkages between agricultural diversification, agribusiness and dietary diversity. For instance, the application of precision farming, agro-ecological zones targeted agricultural intensification and gender sensitive land administration, access and tenure in countries experiencing declining farm size could potentially ensure the youth, men and women have equitable and innovative opportunities of access to elements of improved agricultural systems. Smallholder farmers with the majority in rural settings, maintain de facto agricultural diversity. It is essential for any policy design or intervention to take into account the specific country’s context;pay particular attention to socioeconomic capabilities of the rural population along with fiscal capacity and trade-offs. Empirical evidence on the nexus between agricultural diversification and nutrition is mixed and limited.展开更多

文摘Introduction: Food security is one of the greatest challenges that most African countries face. It is a concept that considers not only food quantity but also food quality. The objective of this study was to describe dietary diversity and food security status at the individual level in Cameroonian populations. Methods: A total of 1180 men and women aged 20 and over and living in the West, North West, and Littoral regions of Cameroon were recruited. Data on dietary habits were collected through the frequency of consumption of various food groups. Dietary diversity was assessed using a 24-hour dietary recall. Food security status was determined by combining two indicators (food consumption score and individual food diversity score). Results: The mean dietary diversity score of the population was 3.53 ± 1.44, p Conclusion: The diet diversity of adults living in the West, North West, and Littoral regions of Cameroon is medium. Although half of the study population was food secure, there is a need to implement food security policies further to reduce food insecurity among the Cameroonian population.

文摘This paper offers the first empirical evidence of the impact of COVID-19 on dietary diversity among children and adolescents in urban and rural families by using panel data collected in 2019(before COVID-19)and 2020(during COVID-19)in northern China.Our study uses panel data from 2,201 primary school students and 1,341 junior high-school students to apply the difference in differences(DID)method to estimate the impact of COVID-19 on dietary diversity among students in urban and rural families.We found that the dietary diversity score(DDS)of rural students decreased by 0.295 points(p<0.01)compared with that of urban students during COVID-19.Specifically,COVID-19 significantly reduced the frequency of rural students'consumption of vegetables by 1.8 percent,protein-rich foods such as soybean products and nuts by 6.0 percent,meats by 4.0 percent,aquatic products by 6.7 percent,and eggs by 5.3 percent,compared with urban students.Further,COVID-19 had a significant negative effect on the dietary diversity of students from low-and middle-income groups,with the DDS of the low-income group decreasing by 0.31 points(p<0.01)and that of the middle-income group by 0.12 points(p<0.1).
文摘BACKGROUND Female infertility with unknown causes(unexplained)remains one of the mysteries in the reproductive health field,where the diagnostic evidence is still weak and the proposed treatments still work with unknown methods.However,several studies have proposed some possible causes and risk factors for unexplained female infertility.AIM To characterize and identify factors associated with unexplained infertility in Sudanese women.METHODS A matched(age and body mass index)case-control study was conducted from March 2021 to February 2022.The study samples were 210 women with unexplained infertility(UI)and 190 fertile women of reproductive age who were attending the maternity hospitals and fertility clinics in Khartoum,Sudan.The risk factors of unexplained infertility were identified using a structured,pretested questionnaire containing information on socio-demographic variables,anthropometrics,clinical diagnosis of infertility,behavioral factors,physical activity assessment,diversity,and consumption of different food groups by the study participants.RESULTS The results showed a higher proportion of women diagnosed with UI were residents of rural areas than controls(21.4%vs 11.1%,P<0.05),and previous miscarriages and/or abortions were more common in fertile women compared with infertile women(13.16%vs 5.71%,P<0.05).Additionally,infertile women had a significantly(P<0.05)higher proportion of family history of infertility(explained and unexplained)compared with controls.Finally,after controlling for the effects of potentially confounding variables using multivariable logistic regression analysis,only marital status,family history of infertility,use of modern contraceptives,smoking,caffeine consumption,physical activity level,meals consumed,other vitamin-A-rich fruits and vegetables,and other vegetables were found to be significant(P<0.05)factors associated with unexplained infertility among Sudanese women.CONCLUSION Married women with a family history of infertility who smoke and consume a high amount of caffeine,who live a sedentary lifestyle,and who consume more than two meals free of vitamin-Arich fruits and/or vegetables and/or other vegetables per day are at the highest risk of developing unexplained infertility.
文摘<strong>Introduction</strong><span><span><span style="font-family:;" "=""><span style="font-family:Verdana;">: Appropriate feeding and consequently good nutritional status </span><span><span style="font-family:Verdana;">of young children largely depends on their caregivers. </span><b><span style="font-family:Verdana;">Aim</span></b><span style="font-family:Verdana;">: The current</span></span><span style="font-family:Verdana;"> study aimed at assessing maternal/caregivers’ current knowledge, attitudes, practices, and beliefs regarding different aspects of infant and young child feeding in Eastern and Central Uganda. </span><b><span style="font-family:Verdana;">Methodology</span></b><span style="font-family:Verdana;">: A cross-sectional survey design with mixed methods employing both qualitative and quantitative methods was used for data collection. </span><b><span style="font-family:Verdana;">Results</span></b><span style="font-family:Verdana;">: The study participants included 556 caregivers and 572 children. Results indicate that most caregivers (77%) were knowledgeable about key infant and young child feeding practices such as breastfeeding, complementary feeding and meal frequency. However, culture </span><span><span style="font-family:Verdana;">and economic hardships were</span><span style="color:red;"> </span><span style="font-family:Verdana;">a major barrier to the applicability of this</span></span><span style="font-family:Verdana;"> knowledge. Nearly all (98%) children were ever breastfed with 41% having been initiated on breast milk in the first hour after birth and 68% of all the children below 6 months exclusively breastfed. Three percent of the children aged 6 - 23 months were classified as having either Moderate (2%) or Severe (1%) Acute malnutrition. The median birth weight was 3.2</span></span></span></span><span><span><span style="font-family:;" "=""> </span></span></span><span><span><span style="font-family:;" "=""><span style="font-family:Verdana;">Kgs with nine percent of the children classified as underweight at birth. The majority (78%) of the children consumed foods from at least four food groups however only </span><span style="font-family:Verdana;">44% consumed heme-rich animal flesh food such as meat, poultry, organ</span><span style="font-family:Verdana;"> meats and fish, 29% consumed milk and milk products while only 11% consumed eggs. The barriers to improved nutritional status and health-seeking</span><span style="color:red;"> </span><span style="font-family:Verdana;">behaviour in children from both regions were largely similar. Some of these included cultural practices which prohibit children from eating certain foods and lack of drugs in the health facilities. Lack of male involvement was a key barrier to health-seeking behaviour and the nutritional well-being of children. Males were, however, more knowledgeable about the key childcare practices that are critical to positive outcomes because they listen to radios, have access to social media and usually congregate at bars where this information is disseminated and exchanged. </span><b><span style="font-family:Verdana;">Conclusion:</span></b><span style="font-family:Verdana;"> There should be continuous sensitization of mothers on the benefits of breastfeeding with special focus on early initiation and exclusive breastfeeding as well as child feeding practices during ill</span><span style="font-family:Verdana;">ness. To increase protein intake in children 6 - 23 months, interventions </span><span style="font-family:Verdana;">aimed at increasing consumption of these vital nutrients such as promotion of nutrition-sensitive agricultural enterprises like rearing of small livestock and chickens should be emphasized. Consumption of these foods is critical, especially during pregnancy and infancy. Finally, male involvement in maternal and child feeding should be encouraged.</span></span></span></span>
