Methods Four hundred and two preschool children (217 males, 185 females), aged 3-5 years, whose height for age and/or weight for age were less than the reference level, were selected as subjects from 7 kindergartens in Beijing Fangshan District. The subjects were divided randomly into control group (CG, 201) and yogurt supplemented group (YG, 201). Each subject in YG was given one serving of yogurt (125 g) for 5 days a week from March to December in 2001, while nothing additional was provided to CG. All subjects kept their usual diet during the study. Anthropometry (body height and weight and upper-arm circumference) and the bone mineral density (BMD) of forearm were measured every 3 months. Disease status and dietary intake were also recorded and assessed. Results The intake of calcium, zinc, and vitamin B2 in YG was significantly higher than that in CG. The incidence and duration of upper-respiratory infection and diarrhea of children in YG were significantly less than those in CG. The height gain of children in YG was significantly higher than that in CG after yogurt was supplemented for 3, 6, and 9 months (P<0.05) (1.90±0.49 cm vs 1.77±0.54 cm, 3.83±0.57cm vs 3.64±0.66 cm and 5.43±0.69 cm vs 5.24±0.76 cm, respectively). The weight gain of children in YG was significantly higher than that in CG after yogurt was supplemented for 3, 6, and 9 months (P<0.05) (0.70±0.43 kg vs 0.49±0.35 kg, 0.98±0.62 kg vs 0.80±0.60 kg and 1.42±0.76 kg vs 1.20±0.67 kg, respectively). The BMD of children in YG was significantly higher than that in CG after yogurt was supplemented for 9 months (P<0.05) (0.415±0.058 g/cm2 vs 0.400±0.065 g/cm2). Conclusion Yogurt is beneficial to the improvement of calcium, zinc, and vitamin B2 intake, the decreasing of the incidence and duration of upper-respiratory infection and diarrhea, and the promotion of the health and the growth and development of preschool children.展开更多

There is little information regarding adverse reactions to the Essen and 2-1-1 regimens in preschool children（aged 0-6）. We reexamined the outcomes of 1,109 preschool children who were vaccinated using SPEEDA under the Essen regimen between January 2011 and December 2012 and 1,267 preschool children under the 2-1-1 regimen between January 2013 and December 2014. We find that, in preschool children, the febrile reaction after the first 2-dose injection in the 2-1-1 regimen was significantly higher than that induced by the first 1-dose in the Essen procedure. Thus, we recommend that the Essen regimen should still be used for rabies PEP in preschool children.展开更多

Methods A double-blind, placebo-controlled trial was conducted in 156 growth retarded preschool children. They were randomly assigned to five groups: supplemental control (S-control, n=28), zinc supplementation(+Zn, 3.5mg Zn/day, n=34), zinc and calcium supplementation (+ZnCa, 3.5mg Zn+250mg Ca/day, n=37), zinc and calcium and vitamin A supplementation (+ZnCaVA, 3.5mgZn +250mgCa+200gVA/day, n=28), Calcium and vitamin A supplementation (+CaVA, 250mgCa + 200gVA/day, n=29). Another 34 children with normal height were selected as normal control (N-control). Supplementation continued for twelve months. Results The height gain in +Zn group (7.84cm per year) and +ZnCa group (7.70 cm per year) was significantly higher than that in S-control group (6.74 cm per year, P<0.05); The weight gain in +ZnCaVA group (2.55kg per year) and +CaVA group (2.57 kg per year) was also significantly higher than that in S-control group (2.19kg per year, P<0.05); The average days of illness in each supplementation group were lower than that in S-control (13 days per year compared with 23 days per year). No significant difference was observed on bone age. Conclusion Zinc and Zinc+Calcium supplementation can improve the height gain, and vitamin A can improve weight gain in growth retarded preschool children, but do not affect the maturity of bone. Micronutrient supplementation can lower the morbidity of these children.展开更多

Preschool children and their families with regular activities at public schools were invited to paticipate in the study. The following characteristics were assessed: Socio-demographic condictions, clinical health, anthropometric, biochemical, lifestyle and data on food consumption. The 56 healthy children were divided into two groups, overweight(C1) and non-overweight(C2), as well as their mothers, respectively, in overweight(M1) and non-overweight(M2). Nutritional status was defined according to results obtained through the Anthro? Software for nutritional analysis. RESULTS Thirty-five children were male, with mean age of 4.44 ± 1.0 years old. Eighty-nine percent of them were eutrophic, 86.7% were sedentary and they had five meals a day. Body mass index(BMI) for age and total cholesterol(TC) was higher on C1(P = 0.0001) and high density lipoprotein cholesterol(HDL-c) was higher on C2. Mothers were 32.5 ± 7.1 years old, mostly married and employed. Eighty-six percent of them were sedentary and 62.5% were overweight with BMI = 26.38 ± 5.07 kg/m2. Eighteen percent of the overweight mothers had isolated total hypercholesterolemia(TC levels elevated) and 12.5% had low HDL-c levels. The present study showed an association between overweight and obesity during the preschool years and the correspondent mothers' nutritional status of overweight and obesity(OR = 4.96; 95%CI: 0.558-44.17). There was a positive correlation between the food risk associated with CVD by children and mothers when their consumption was 4 times/wk(P = 0.049; r = 0.516) or daily(P = 0.000008; r = 0.892).CONCLUSION Analyzed children showed high rates of physical inactivity, high serum cholesterol levels and high consumption of food associated with risk for CVD and renal disease. Changes in habits should be encouraged early in kindergarten.展开更多

The main objective of this study was to assess the prevalence and risk factors of zinc deficiency among infants and preschool children. Based on a community, the cross-sectional study was conducted in East Gojjam between October 2011 and April 2012. Two hundred and forty infants and preschool children were randomly selected in the study. Data on potential determinants of zinc deficiency were collected using a structured questionnaire. Serum zinc concentration was measured using atomic absorption spectrometer. Statistical analysis was done using ANOVA, independent sample student＇s t-test and linear regression model. The mean serum zinc concentration of infants and preschool children was 62.98 （±13.03） μg/dL in 95% confidence interval （CI） between 61.32 and 64.63 （i.e., 95% CI： 61.32, 64.63）. About 57,1% of the subjects were zinc deficient. The main determinants of low serum zinc status of infants and preschool children were age and number of family members living on the same land. Zinc status of older children was 3.67 μg/dL （95% CI： -5.58, -1.77） lower than children who were aged 6-10 months. Serum zinc status of infants and preschool children is decreased by 0.83 p.g/dL （95% CI： -1.36, -0.30） with each additional family member. Food insecurity, dietary diversity, sex, child health, anthropometric indices, maternal education and wealth index were not associated with serum zinc status. Zinc deficiency among infants and preschool children is highly prevalent. Such potential deficiencies require urgent attention, including complementary food preparation education, traditional phytate reduction method and family planning implementation recommended in the study area.展开更多

Evidence from young children suggests that trajectories of number learning differ for children having different home numeracy experiences. Children involved in higher frequency of direct numeracy practice tend to have higher numeracy skills, but the result becomes more complicated when considering the types of home numeracy activities. The relationship between the home numeracy experience and preschool children＇s nurneracy development may shed light on how children acquire number skills and develop their mathematics competence.展开更多

A total of 550 healthy preschool children aged 3 to 6 years old from 6 kindergartens were enrolled. Comprehensive ocular examinations, including measurement of visual acuity, axial length, intraocular pressure and slit-lamp examination before cycloplegia, as well as refraction measurement and sweptsource optical coherence tomography(SS-OCT) examination after cycloplegia, were performed. The macular ChT in each sector of the ETDRS grid was measured by the builtin software of SS-OCT.RESULTS: The mean central ChT of the participants was 312±59 μm. The mean axial length and spherical equivalent refraction were 22.36±0.72 mm and 1.51±0.83 D, respectively. Axial length increased with age(P<0.001), while the spherical equivalent refraction was similar among different age groups. Similarly, no significant difference was observed in ChT in all sectors among different age groups(all P>0.05). The central ChT of 3-4, 5 and 6 years old children was 314±59 μm, 312±60 μm and 312±59 μm, respectively(P=0.920). No difference was observed in ChT in most of the sectors between genders. No statistical significant difference was observed among different refractive groups(all P>0.05), though the ChT of each sector seemed to be smaller in myopic children. Axial length and weight were the independent factors of central Ch T. Children with longer axial length(β=-21.184, P<0.001) and smaller weight(β=1.502, P=0.041) tended to have thinner choroid.CONCLUSION: In preschool children, the ChT remains relatively stable with age, while a negative association between ChT and axial length existed. This will be helpful to elucidate the characteristics of ChT during the early refractive development.展开更多

A study consisting of cross-sectional (survey) and longitudinal (follow-up) component was designed by including a randomly selected group of participants (n = 322) from 10 Head Start sites provided with free bicycle helmets along with a subgroup of prior helmet owners (n = 68) from the other random group (n = 285). All participants received bicycle helmet education. Helmet use surveys were conducted in May (1st Survey) and November 2008 (2nd Survey). The helmet owners were followed up to determine IRs, and incidence rate ratios (IRRs) for head and facial injuries. PAFs were computed using IRs as well as helmet use rates and IRRs. Helmet use rates increased significantly from the 1st to the 2nd Survey. The mean follow-up person-time was 5 months. The IRs for head, face (all portions), and face (upper/mid portions) injuries were higher in non-helmeted than helmeted riders. By using IRs, PAFs for the 3 injuries among the riders in both groups of helmet owners were 77%, 22%, and 32% respectively. The PAFs for each of the above injuries decreased by about 10% as helmet use rates increased. The magnitude of and changes in preventable head and facial injuries following free bicycle helmet distribution and education among helmeted riders was elucidated in this Head Start preschool children population.展开更多

This study aimed to determine the characteristics of central body fat distribution in Thai preschool children and to examine factors that could influence on body fat distribution of children. Methods: The total 811, 5 - 6 years old children were randomly sampled from 9 primary schools in Saraburi province. Body weight and height were measured in each child. Waist circumference (WC) was measured at the umbilicus level and hip circum-ference (HC) at the level yielding maximum circumference over buttock. Subcutaneous skinfold was measured on biceps, triceps, subscapular, suprailiac and abdominal regions. Total body fat (TBF) was measured with bioelectrical impedance analyzer. Results: Mean values of WC, waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) of boys were not different from those of girls. Even though trunk skinfolds of both genders were similar, girls tended to have slightly greater biceps, triceps and subscapular skinfolds than boys. Strongly positive correlation was found between WC, WHtR, trunk skinfold and child’s BMI (p = 0.01) as well as between WC, WHtR, trunk skinfold and child’s TBF (p = 0.01). Multiple regression analysis demonstrated, in both genders, that BMI, age and TBF were strongly associated with WC (Adjusted R2 0.92 - 0.93) and WHtR (Adjusted R2 0.90 - 0.92) and that BMI and TBF were strongly associated with trunk skinfold (Adjusted R2 0.88 - 0.89). The association between WHR and TBF for boys and between WHR and BMI for girls were found to be weak in this study. Conclusion: No gender difference in body fat distribution indices was found in Thai preschool children. Change in central body fat distribution of children could be strongly influenced by their changes in age, BMI and TBF.展开更多

文摘Objective To investigate the effect of yogurt supplementation on the growth of preschool children in Beijing suburbs. Methods Four hundred and two preschool children (217 males, 185 females), aged 3-5 years, whose height for age and/or weight for age were less than the reference level, were selected as subjects from 7 kindergartens in Beijing Fangshan District. The subjects were divided randomly into control group (CG, 201) and yogurt supplemented group (YG, 201). Each subject in YG was given one serving of yogurt (125 g) for 5 days a week from March to December in 2001, while nothing additional was provided to CG. All subjects kept their usual diet during the study. Anthropometry (body height and weight and upper-arm circumference) and the bone mineral density (BMD) of forearm were measured every 3 months. Disease status and dietary intake were also recorded and assessed. Results The intake of calcium, zinc, and vitamin B2 in YG was significantly higher than that in CG. The incidence and duration of upper-respiratory infection and diarrhea of children in YG were significantly less than those in CG. The height gain of children in YG was significantly higher than that in CG after yogurt was supplemented for 3, 6, and 9 months (P<0.05) (1.90±0.49 cm vs 1.77±0.54 cm, 3.83±0.57cm vs 3.64±0.66 cm and 5.43±0.69 cm vs 5.24±0.76 cm, respectively). The weight gain of children in YG was significantly higher than that in CG after yogurt was supplemented for 3, 6, and 9 months (P<0.05) (0.70±0.43 kg vs 0.49±0.35 kg, 0.98±0.62 kg vs 0.80±0.60 kg and 1.42±0.76 kg vs 1.20±0.67 kg, respectively). The BMD of children in YG was significantly higher than that in CG after yogurt was supplemented for 9 months (P<0.05) (0.415±0.058 g/cm2 vs 0.400±0.065 g/cm2). Conclusion Yogurt is beneficial to the improvement of calcium, zinc, and vitamin B2 intake, the decreasing of the incidence and duration of upper-respiratory infection and diarrhea, and the promotion of the health and the growth and development of preschool children.

文摘Post-exposure prophylaxis（PEP） has proved to be the most important measure for rabies prevention and control. There is little information regarding adverse reactions to the Essen and 2-1-1 regimens in preschool children（aged 0-6）. We reexamined the outcomes of 1,109 preschool children who were vaccinated using SPEEDA under the Essen regimen between January 2011 and December 2012 and 1,267 preschool children under the 2-1-1 regimen between January 2013 and December 2014. We find that, in preschool children, the febrile reaction after the first 2-dose injection in the 2-1-1 regimen was significantly higher than that induced by the first 1-dose in the Essen procedure. Thus, we recommend that the Essen regimen should still be used for rabies PEP in preschool children.
文摘Objective To study the relationship between micronutrient supplementation and children growth. Methods A double-blind, placebo-controlled trial was conducted in 156 growth retarded preschool children. They were randomly assigned to five groups: supplemental control (S-control, n=28), zinc supplementation(+Zn, 3.5mg Zn/day, n=34), zinc and calcium supplementation (+ZnCa, 3.5mg Zn+250mg Ca/day, n=37), zinc and calcium and vitamin A supplementation (+ZnCaVA, 3.5mgZn +250mgCa+200gVA/day, n=28), Calcium and vitamin A supplementation (+CaVA, 250mgCa + 200gVA/day, n=29). Another 34 children with normal height were selected as normal control (N-control). Supplementation continued for twelve months. Results The height gain in +Zn group (7.84cm per year) and +ZnCa group (7.70 cm per year) was significantly higher than that in S-control group (6.74 cm per year, P<0.05); The weight gain in +ZnCaVA group (2.55kg per year) and +CaVA group (2.57 kg per year) was also significantly higher than that in S-control group (2.19kg per year, P<0.05); The average days of illness in each supplementation group were lower than that in S-control (13 days per year compared with 23 days per year). No significant difference was observed on bone age. Conclusion Zinc and Zinc+Calcium supplementation can improve the height gain, and vitamin A can improve weight gain in growth retarded preschool children, but do not affect the maturity of bone. Micronutrient supplementation can lower the morbidity of these children.

文摘Many eating behaviors form in childhood,and some unhealthy behaviors may persist into adulthood and have potential impacts on people＇s health.This study evaluated the effectiveness of behavioral intervention in reducing consumption of Western fast food,sweetened beverages,fried food in preschool children,and changing parents＇ rewarding behaviors that encourage the consumption of the unhealthy foods.The research was a cluster randomized trial of seven kindergartens,involving 1138 children aged 3–6 years and their parents in Beijing,China.Parents and children allocated to the intervention group received two lectures and printed resources,including behavior cards,educational sheets.Children＇s behavior cards,applied with behavior-changing techniques,were used to intervene,and monitor behavior changes over time.Children in the control group just followed their usual health education curriculum in kindergartens.Intervention effects on food consumption behaviors were assessed by examining pre-and post-questionnaires.Of the 1138 children screened at baseline,880（77.3%） were measured at the end of the intervention period.The intervention lasted from March to June in 2010.The results showed that consumption of Western fast food,sweetened beverages,and fried food was decreased among the intervention group（P〈0.001）.Proportions of parents using Western fast food as rewards for their children were decreased（P=0.002）.From March to June 2010,the frequency of each target behavior in children tended to decrease over the intervention period（P〈0.001）.Most parents favored regularly-delivered behavior cards or materials for behavioral intervention.In conclusion,the behavioral intervention encourages the healthier eating behaviors of children and reduces the parents＇ practice of using unhealthy foods as reward.
文摘AIM To investigate the prevalence of nutritional parameters of risk for cardiovascular disease(CVD) and kidney diseases in healthy preschool children.METHODS This is an observational cross-sectional study with 60 healthy children, of both genders, aged two to six years old and 56 mothers, in Belo Horizonte, Minas Gerais, Brazil. Preschool children and their families with regular activities at public schools were invited to paticipate in the study. The following characteristics were assessed: Socio-demographic condictions, clinical health, anthropometric, biochemical, lifestyle and data on food consumption. The 56 healthy children were divided into two groups, overweight(C1) and non-overweight(C2), as well as their mothers, respectively, in overweight(M1) and non-overweight(M2). Nutritional status was defined according to results obtained through the Anthro? Software for nutritional analysis. RESULTS Thirty-five children were male, with mean age of 4.44 ± 1.0 years old. Eighty-nine percent of them were eutrophic, 86.7% were sedentary and they had five meals a day. Body mass index(BMI) for age and total cholesterol(TC) was higher on C1(P = 0.0001) and high density lipoprotein cholesterol(HDL-c) was higher on C2. Mothers were 32.5 ± 7.1 years old, mostly married and employed. Eighty-six percent of them were sedentary and 62.5% were overweight with BMI = 26.38 ± 5.07 kg/m2. Eighteen percent of the overweight mothers had isolated total hypercholesterolemia(TC levels elevated) and 12.5% had low HDL-c levels. The present study showed an association between overweight and obesity during the preschool years and the correspondent mothers' nutritional status of overweight and obesity(OR = 4.96; 95%CI: 0.558-44.17). There was a positive correlation between the food risk associated with CVD by children and mothers when their consumption was 4 times/wk(P = 0.049; r = 0.516) or daily(P = 0.000008; r = 0.892).CONCLUSION Analyzed children showed high rates of physical inactivity, high serum cholesterol levels and high consumption of food associated with risk for CVD and renal disease. Changes in habits should be encouraged early in kindergarten.
文摘Zinc deficiency is a public health concern and is the most prevalent micronutrient deficiencies in developing countries. The main objective of this study was to assess the prevalence and risk factors of zinc deficiency among infants and preschool children. Based on a community, the cross-sectional study was conducted in East Gojjam between October 2011 and April 2012. Two hundred and forty infants and preschool children were randomly selected in the study. Data on potential determinants of zinc deficiency were collected using a structured questionnaire. Serum zinc concentration was measured using atomic absorption spectrometer. Statistical analysis was done using ANOVA, independent sample student＇s t-test and linear regression model. The mean serum zinc concentration of infants and preschool children was 62.98 （±13.03） μg/dL in 95% confidence interval （CI） between 61.32 and 64.63 （i.e., 95% CI： 61.32, 64.63）. About 57,1% of the subjects were zinc deficient. The main determinants of low serum zinc status of infants and preschool children were age and number of family members living on the same land. Zinc status of older children was 3.67 μg/dL （95% CI： -5.58, -1.77） lower than children who were aged 6-10 months. Serum zinc status of infants and preschool children is decreased by 0.83 p.g/dL （95% CI： -1.36, -0.30） with each additional family member. Food insecurity, dietary diversity, sex, child health, anthropometric indices, maternal education and wealth index were not associated with serum zinc status. Zinc deficiency among infants and preschool children is highly prevalent. Such potential deficiencies require urgent attention, including complementary food preparation education, traditional phytate reduction method and family planning implementation recommended in the study area.
文摘With the acceleration of the process of globalization, English has become a bridge for communication.

English education of pre-school children is a hot topic, and its feasibility has been widely discussed, some people think that pre-school children age advantage, the best stage to learn the language; opponents that should not have to prc-schoo! children increased burden is too early learning English may lead to confusion of English and the mother tongue. This paper attempts to analyse the advantages of English education in pre-school children dcrnonstrate the feasibility of the English education of pre-school children and prc-school English education to make a few suggestions.
文摘This mini-review focuses on the question of how home numeracy experience （i.e.,number-related activities at home） may affect a child＇s numeracy development. Evidence from young children suggests that trajectories of number learning differ for children having different home numeracy experiences. Children involved in higher frequency of direct numeracy practice tend to have higher numeracy skills, but the result becomes more complicated when considering the types of home numeracy activities. The relationship between the home numeracy experience and preschool children＇s nurneracy development may shed light on how children acquire number skills and develop their mathematics competence.

文摘AIM: To explore the distribution pattern of macular choroidal thickness(ChT) and its association with age as well as refractive status in Chinese preschoolers.METHODS: School-based, cross-sectional study. A total of 550 healthy preschool children aged 3 to 6 years old from 6 kindergartens were enrolled. Comprehensive ocular examinations, including measurement of visual acuity, axial length, intraocular pressure and slit-lamp examination before cycloplegia, as well as refraction measurement and sweptsource optical coherence tomography(SS-OCT) examination after cycloplegia, were performed. The macular ChT in each sector of the ETDRS grid was measured by the builtin software of SS-OCT.RESULTS: The mean central ChT of the participants was 312±59 μm. The mean axial length and spherical equivalent refraction were 22.36±0.72 mm and 1.51±0.83 D, respectively. Axial length increased with age(P<0.001), while the spherical equivalent refraction was similar among different age groups. Similarly, no significant difference was observed in ChT in all sectors among different age groups(all P>0.05). The central ChT of 3-4, 5 and 6 years old children was 314±59 μm, 312±60 μm and 312±59 μm, respectively(P=0.920). No difference was observed in ChT in most of the sectors between genders. No statistical significant difference was observed among different refractive groups(all P>0.05), though the ChT of each sector seemed to be smaller in myopic children. Axial length and weight were the independent factors of central Ch T. Children with longer axial length(β=-21.184, P<0.001) and smaller weight(β=1.502, P=0.041) tended to have thinner choroid.CONCLUSION: In preschool children, the ChT remains relatively stable with age, while a negative association between ChT and axial length existed. This will be helpful to elucidate the characteristics of ChT during the early refractive development.
文摘Objective:The aim of the paper is to see how educational and working status of the parents affect the nutritional and immunization status of preschool children in India.Methods:We have used data of more than 24 000 preschool children spread over different states in India.The data were collected by National Family Health Survey(NFHS-2) in 1998-99.For assessing the nutritional status,only the Z-scores of weight-forheight (WHZ) have been computed and for immunization status,it has been seen whether BCG,DPT3,Polio3 and measles have been administered.Children who fall below -2SD(-3SD) from median are considered to be moderately(severely) malnourished.Results:According to the NFHS-2 data,70%of children are vaccinated by BCG,50%receive the full course of DPT,54%get all the three dozes of polio and only 42%are protected from measles by vaccination in India.The percentages of moderately and severely wasted children in India are 12.1 and 2.8,respectively.There is a marked regional variation of these percentages.Bivariate and multivariate analysis clearly points to the need of educational status of mothers rather than fathers for proper nutritional and immunization status of preschool children.Parents’occupation and working status also have some effect,but not so pronounced as parents’education.Conclusion:The Indian preschool children need particular attention for high risk of wasting and low immunization.The prevalence of malnutrition can be arrested more by improving the mother’s education level rather than their fathers and by raising the standard of living of their house-holds.

文摘The objectives of the study were to determine helmet use rates, incidence rates (IRs) of head and facial injuries for population attributable fraction (PAF) estimation, and to elucidate the magnitude of and changes in PAFs as the result of helmet use changes among preschool children. A study consisting of cross-sectional (survey) and longitudinal (follow-up) component was designed by including a randomly selected group of participants (n = 322) from 10 Head Start sites provided with free bicycle helmets along with a subgroup of prior helmet owners (n = 68) from the other random group (n = 285). All participants received bicycle helmet education. Helmet use surveys were conducted in May (1st Survey) and November 2008 (2nd Survey). The helmet owners were followed up to determine IRs, and incidence rate ratios (IRRs) for head and facial injuries. PAFs were computed using IRs as well as helmet use rates and IRRs. Helmet use rates increased significantly from the 1st to the 2nd Survey. The mean follow-up person-time was 5 months. The IRs for head, face (all portions), and face (upper/mid portions) injuries were higher in non-helmeted than helmeted riders. By using IRs, PAFs for the 3 injuries among the riders in both groups of helmet owners were 77%, 22%, and 32% respectively. The PAFs for each of the above injuries decreased by about 10% as helmet use rates increased. The magnitude of and changes in preventable head and facial injuries following free bicycle helmet distribution and education among helmeted riders was elucidated in this Head Start preschool children population.
文摘Background: Central obesity is associated with adverse health outcomes. This study aimed to determine the characteristics of central body fat distribution in Thai preschool children and to examine factors that could influence on body fat distribution of children. Methods: The total 811, 5 - 6 years old children were randomly sampled from 9 primary schools in Saraburi province. Body weight and height were measured in each child. Waist circumference (WC) was measured at the umbilicus level and hip circum-ference (HC) at the level yielding maximum circumference over buttock. Subcutaneous skinfold was measured on biceps, triceps, subscapular, suprailiac and abdominal regions. Total body fat (TBF) was measured with bioelectrical impedance analyzer. Results: Mean values of WC, waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) of boys were not different from those of girls. Even though trunk skinfolds of both genders were similar, girls tended to have slightly greater biceps, triceps and subscapular skinfolds than boys. Strongly positive correlation was found between WC, WHtR, trunk skinfold and child’s BMI (p = 0.01) as well as between WC, WHtR, trunk skinfold and child’s TBF (p = 0.01). Multiple regression analysis demonstrated, in both genders, that BMI, age and TBF were strongly associated with WC (Adjusted R2 0.92 - 0.93) and WHtR (Adjusted R2 0.90 - 0.92) and that BMI and TBF were strongly associated with trunk skinfold (Adjusted R2 0.88 - 0.89). The association between WHR and TBF for boys and between WHR and BMI for girls were found to be weak in this study. Conclusion: No gender difference in body fat distribution indices was found in Thai preschool children. Change in central body fat distribution of children could be strongly influenced by their changes in age, BMI and TBF.

文摘In this study,990 preschool children of 3-to 6-year-old were selected as participants to explore the influence of shyness and unsociability on peer play behavior in preschool children,focusing on the mediating and moderating roles of playfulness.The study employed the Child Social Preference Scale,Children’s Playfulness Scale,and Penn Interactive Peer Play Scale to assess the variables.The findings indicate that preschool children’s shyness and unsociability negatively predict their play interaction and positively predict their play disruption and play disconnection.Playfulness partially mediates and moderates the relationships between shyness and unsociability with peer play behavior.To promote the social development of shy and unsociable preschool children,it is imperative for teachers and parents to respect and accept the characteristics of children,guide them in adopting positive problem-solving strategies,and improve their playfulness.
