Despite the ongoing problems of undernutrition and infectious disease, obesity and overweight have become a major problem in developing countries, including Bangladesh. This cross-sectional study was undertaken to determine the prevalence of obesity, overweight and underweight among school children aged 6-12 years in Bangladesh. The study was conducted from June 2012 to May 2013 and the study sample comprised 1768 children (980 boys; 788 girls) from eight purposively selected schools in different areas of Dhaka city. Students were interviewed about their diet and physical activity, and anthropometric measurements were made, including height, weight, mid-upper-arm circumference (MUAC), waist circumference, hip circumference and body mass index (BMI). Undernutrition, overweight and obesity were defined using internationally accepted BMI cut-off points. Mean height, weight, BMI, MUAC, waist circumference and hip circumference values were found to be higher in boys than in girls, except at age 12 when these were found to be significantly higher in girls than in boys (p<0.05). The mean prevalence of overweight was 10.0% (boys 10.2%; girls 9.8%), and that of obesity 5.0% (boys 4.3%; girls 5.8%). The prevalence of underweight was 16.3% in boys and 12.7% in girls. The prevalence of underweight was significantly higher in poor than in rich children (22.1% vs 11.2%) and that of obesity was higher in rich than in poor children (9.9% vs 1.3%; p<0.001). A family history of obesity and hypertension emerged as a significant predictor of developing overweight and obesity (p<0.001). The data suggest that underweight and obesity co-exist in urban areas of Bangladesh, posing a challenge for the nutritional health of Bangladeshi children.
尽管发展中国家（包括孟加拉国）仍然存在营养不足和传染病等问题，但肥胖和超重已成为一个主要问题。本横断面研究旨在确定孟加拉国 6-12 岁学龄儿童的肥胖、超重和体重不足的患病率。该研究于 2012 年 6 月至 2013 年 5 月进行，研究样本包括来自达卡市不同地区的 8 所选定学校的 1768 名儿童（980 名男孩；788 名女孩）。学生接受了有关饮食和体育活动的访谈，并进行了人体测量，包括身高、体重、中上臂围（MUAC）、腰围、臀围和体重指数（BMI）。使用国际公认的 BMI 切点定义营养不良、超重和肥胖。除了 12 岁时女孩的身高、体重、BMI、MUAC、腰围和臀围显著高于男孩外，男孩的平均身高、体重、BMI、MUAC、腰围和臀围均高于女孩（p＜0.05）。超重的平均患病率为 10.0%（男孩 10.2%；女孩 9.8%），肥胖的平均患病率为 5.0%（男孩 4.3%；女孩 5.8%）。男孩体重不足的患病率为 16.3%，女孩为 12.7%。贫困儿童体重不足的患病率明显高于富裕儿童（22.1%比 11.2%），而肥胖的患病率则相反（9.9%比 1.3%；p＜0.001）。肥胖和高血压家族史是超重和肥胖发生的显著预测因素（p＜0.001）。数据表明，孟加拉国城市地区存在消瘦和肥胖并存的情况，这对孟加拉国儿童的营养健康构成了挑战。
