摘要:
目的 了解上海市中心城区学龄前儿童的超重和肥胖流行现状,探究膳食营养、饮食行为和家庭因素与儿童肥胖的关系,为制定预防儿童肥胖措施提供依据。 方法 选取上海市中心城区2 所幼儿园共588 名3~5 岁儿童进行研究。采用成组设计的研究方法,调查117 名超重或肥胖儿童(超重肥胖组)和471 名正常儿童(正常对照组)连续3 d 的膳食摄入情况、饮食行为、家庭环境等;并对儿童的身高、体重进行体格测量。使用SPSS 16.0 进行数据处理,用多因素logistic 回归分析儿童膳食营养、饮食行为、家庭因素与超重和肥胖的关系。 结果 调查儿童中超重和肥胖率分别为15.31%和4.59%。超重肥胖组儿童膳食能量、脂肪摄入量明显高于正常对照组(P < 0.05)。多因素分析发现,进食速度快(OR=3.012,95%CI:1.475~6.150),出生体重大(OR=1.708,95%CI:1.229~2.375),父母一方或双方超重或肥胖(OR=2.026,95%CI:1.065~3.855)是超重和肥胖发生的危险因素;摄入海产品频率高(OR=0.376,95%CI:0.186~0.759),母亲文化程度高(OR=0.431,95%CI:0.227~0.819)是超重和肥胖的保护因素。 结论 被调查儿童的超重和肥胖率较高;膳食营养、饮食习惯和家庭因素与超重和肥胖的发生密切相关。 Abstract:Objective To examine the prevalence of overweight and obesity among preschool children in downtown Shanghai, and to investigate the correlation of overweight and obesity with dietary nutrition, eating behaviors, and family factors, in order to provide evidence for public health policy development. Methods A total of 588 children aged 3-5 years old from two kindergartens in downtown areas of Shanghai were enrolled. A group-matched study was conducted among 117 overweight or obese children (overweight/obesity group) and 471 healthy children (control group). Their dietary intakes for 3 days, eating behaviors, and family environment were assessed. Anthropometric measurements, including height and weight, were conducted. SPSS 16.0 software was applied for χ2 test and multivariate logistic analysis. Results The prevalence of overweight and obesity in the selected children were 15.31% and 4.59%, respectively. The daily dietary energy and fat intakes of the overweight/obesity group were higher than those of the control group (P < 0.05). The results of the multivariate analysis revealed that taking food fast (OR=3.012, 95%CI: 1.475-6.150), high birth weight (OR=1.708, 95%CI: 1.229-2.375), and parental overweight or obesity (OR=2.026, 95%CI: 1.065-3.855) were risk factors of overweight and obesity; while high frequency of eating seafood (OR=0.376, 95%CI: 0.186-0.759) and high maternal education level (OR=0.431, 95%CI: 0.227-0.819) were protective factors. Conclusion The prevalence of overweight and obesity are high among the investigated children. Dietary nutrition, eating behaviors, and family factors are closely related to overweight and obesity in preschool children.
