To assess the prevalence of overweight among Chinese preschool children and to explore risk factors of childhood obesity focusing on parental characteristics, feeding practice and lifestyle.
Data on 930 families with 2- to 6-year-old children in five kindergartens were obtained in a cross sectional study. Families were randomly selected from two of all six urban districts in Beijing, China. Information on parental characteristics, dietary habits, lifestyle habits, and feeding practice was collected by parental self-report questionnaires. The children's stature and weight were measured in light clothing and without shoes. Overweight and obesity were defined according to international cut-off values, as proposed by the International Obesity Task Force. Multivariate regression analysis was used to explore risk factors of child overweight.
The overall prevalence of overweight and obesity was 10.7% and 4.2%, respectively, and increased with age. The prevalence of child overweight was 14.1% and 7.5% in obese and non-obese families, respectively. Significant associations were observed between child and parent characteristics for overweight, frequency of eating in restaurant, television hours, and hours of physical activity. Child overweight was associated with parental overweight (Odds Ratio [OR] 2.43, 95% CI 0.78, 6.59), low maternal education level (OR 2.22, 95% CI 1.39, 3.55), food restriction (OR 2.68, 95% CI 1.64, 4.29), and television watching >2h/d (OR 1.56, 95% CI 1.17, 2.09), after adjusting for sex, age, family income and kindergarten (for cluster study design).
Overweight prevalence among Chinese preschool children in Beijing is comparable to some European countries. Prevention strategies should include identified lifestyle risk factors.
评估中国学龄前儿童超重的患病率，并探讨儿童肥胖的危险因素，重点关注父母特征、喂养方式和生活方式。
在一项横断面研究中，获取了来自五所幼儿园的930个有2至6岁儿童的家庭的数据。这些家庭是从中国北京所有六个城区中的两个城区随机选取的。通过父母自填问卷收集有关父母特征、饮食习惯、生活习惯和喂养方式的信息。儿童的身高和体重在穿着轻便衣物且不穿鞋的情况下进行测量。超重和肥胖根据国际肥胖问题工作组提出的国际临界值来定义。采用多变量回归分析来探讨儿童超重的危险因素。
超重和肥胖的总体患病率分别为10.7%和4.2%，且随年龄增长而增加。肥胖家庭和非肥胖家庭中儿童超重的患病率分别为14.1%和7.5%。在儿童和父母特征、外出就餐频率、看电视时间以及体育活动时间方面，观察到超重之间存在显著关联。在调整了性别、年龄、家庭收入和幼儿园（针对整群研究设计）后，儿童超重与父母超重（比值比[OR] 2.43，95%置信区间0.78，6.59）、母亲低教育水平（OR 2.22，95%置信区间1.39，3.55）、食物限制（OR 2.68，95%置信区间1.64，4.29）以及每天看电视>2小时（OR 1.56, 95%置信区间1.17, 2.09）相关。
北京中国学龄前儿童的超重患病率与一些欧洲国家相当。预防策略应包括已确定的生活方式危险因素。
