目的了解深圳市学龄儿童超重和单纯性肥胖的现状,探讨其原因。方法用整群抽样的方法抽取小学生3 008人,年龄范围7~12岁,以常规方法测量身高、体质量,分别用“身高标准体重”和BMI法进行筛查,对2种标准筛查结果进行比较。结果用“身高标准体质量”法检出体质量超标儿童342人,体质量超标率为11.4%;肥胖儿童419人,肥胖率为13.9%。用BMI法检出体质量超标儿童397人,体质量超标率为13.2%;肥胖儿童284人,肥胖率为9.4%。2种方法筛选出体质量超标和肥胖的结果存在明显差异,有统计学意义(P=0.002、P=0.000)。同时在各年龄段和不同性别不同年龄段差异有统计学意义。结论目前仍在广泛使用的“身高标准体质量”存在一定缺陷,而BMI法具有现实性和前瞻性,使用简便,更直观。
Objective To understand the status of overweight and simple obesity in school-age children in Shenzhen and to explore its causes. Methods A total of 3 008 primary school students aged 7-12 years were enrolled in the method of cluster sampling. Height and body mass were measured by the conventional method. The results were screened by “height standard body weight ” and BMI method, respectively. Check the results for comparison. RESULTS: 342 children with excessive body weight were detected with the “standard height body mass” method. The body mass excess rate was 11.4%. The obese children 419 people, the obesity rate was 13.9%. 397 children with excessive body mass were detected by BMI method. The rate of overweight rate of body mass was 13.2%. The number of obese children was 284, the obesity rate was 9.4%. There was a significant difference between the two methods in screening out body weight and obesity (P = 0.002, P = 0.000). At the same time, there are significant differences in different ages and different genders. Conclusions There is a certain defect in “height standard body mass ”, which is still widely used at present. However, the BMI method is practical and forward-looking, easy to use and more intuitive.
