目的 分析上海市浦东新区学龄儿童超重肥胖现状,为进一步筛查学龄儿童超重、预防学龄儿童肥胖提供方向。方法 采用分层随机整群抽样的方法于2017年10月抽取上海市浦东新区1 738名学龄儿童进行体格测量与问卷调查,分别采用国内外不同BMI、腰围和腰高比标准对学龄儿童超重肥胖状况进行评价。 结果 仅使用BMI标准进行超重肥胖评价会遗漏有中心性肥胖风险的儿童,漏查率为7.6%~16.2%;而仅使用中心性肥胖判定标准,也会漏查2.8%~10.9%的全身性肥胖学龄儿童。上海市浦东新区郊区中心镇的学龄儿童超重肥胖率最高(28.6%~39.4%)。男童全身性超重肥胖率为26.2%~35.5%,明显高于女童的18.1%~26.4%,但女童腰围高于正常值的人数(254/766)与男童(316/946)相当,差异无统计学意义(χ2=0.011,P>0.05),应引起关注。此外,一、二年级学龄儿童超重肥胖率明显低于三年级(P＜0.05)。 结论 应同时使用全身性肥胖和中心性肥胖标准对学龄儿童进行筛查,尽早预防学龄儿童超重肥胖,并制定相应干预策略。
Abstract
Objective To analyze the status quo of overweight and obesity among school-age children in Pudong New Area of Shanghai,so as to provide direction for further screening overweight school-age children and preventing school-age children from obesity. Method A total of 1 738 school-age children in Pudong New Area of Shanghai were randomly selected for physical measurement and questionnaire survey in October 2017.Different standards of BMI,waist circumference and waist-to-height ratio were used to evaluate the overweight and obesity status of school-age children. Results Using BMI criteria for overweight and obesity assessments would leave out children at risk of central obesity,and the missing rate was 7.6%-16.2%.Moreover,2.8%-10.9% of school-age children with systemic obesity would be neglected only using the criteria of central obesity.The overweight and obesity rate of school-age children was the highest (28.6%-39.4%) in the suburban central town of Pudong New Area,Shanghai.The systemic overweight and obesity rate of boys was 26.2%-35.5%,which was apparently higher than that of girls,(18.1%-26.4%).Significantly,the study found that the proportion of girls with above-normal waists (254/766) was similar to that of boys (316/946) (χ2=0.011,P>0.05).In addition,the overweight and obesity rate of first-and second- grade children was significantly lower than that of third grade(P＜0.05). Conclusions School-age children should be screened for both systemic and central obesity criteria,so as to prevent overweight and obese as soon as possible.Besides,corresponding intervention strategies are suggested to be formulated.
