上海地区儿童超重和肥胖的评价标准比较

Comparison of references for assessment of overweight and obesity in children of Shanghai

目的比较和分析四种基于身高、体质量的儿童肥胖的评价标准。方法选取上海市2 347名7～8岁的儿童,其中男生1 175名,女生1 172名,测量其身高、体质量,并计算体质量指数。分别采用身高别体质量法(1985)标准(WFH 1985标准)、中国肥胖问题工作组儿童青少年体质指数标准(WGOC标准)、欧洲国际肥胖工作组儿童青少年体质指数标准(IOTF标准)与美国疾病预防控制中心儿童青少年体质指数标准(CDC标准)评价儿童超重和肥胖的发生率。结果①男生超重发生率为IOTF标准明显高于其他三个标准(P<0.05),女生超重发生率IOTF标准明显高于WGOC标准和CDC标准(P<0.05);男生肥胖发生率IOTF标准明显低于其他三个标准(P<0.01);女生肥胖发生率IOTF标准明显低于WFH 1985标准和WGOC标准(P<0.01)。②WFH 1985标准和WGOC标准对肥胖和超重的评价结果差异无统计学意义(P>0.05)。结论WFH 1985标准和WGOC标准比IOTF和CDC标准更适合我国儿童超重和肥胖发生率的筛查。

Objective To compare and analyse four references for assessment of obesity in Chinese children. Methods The height and weight of 2 347 children （1 175 boys and 1 172 girls） aged 7 to 8 years in Shanghai were measured, and their body mass indexes （BMI） were calculated. The prevalences of overweight and obesity were evaluated and compared among reference of Weight for Height 1985 （WFH 1985 reference）, BMI reference of Working Group on Obesity in China （WGOC reference）, BMI reference of Europe International Obesity Task Force （IOTF reference） and BMI reference of Centers for Disease Control and Prevention of American 2000 （CDC reference）. Results The prevalence of overweight in boys evaluated by IOTF reference was significantly higher than those by the other three references （P 〈 0. 05）, and the prevalence of overweight in girls evaluated by IOTF reference was significantly higher than those by WGOC and CDC references （P 〈 0.05）. The prevalence of obesity in boys evaluated by IOTF reference was significantly lower than those by the other three references （P 〈0.01）, and the prevalence of obesity in girls evaluated by IOTF reference was significantly lower than those by WGOC and WFH 1985 references （P 〈 0.01）. There was no significant difference in the evaluation findings of obesity and overweight between WFH 1985 and WGOC references （P 〉 0.05）. Conclusion WFH 1985 and WGOC references are more suitable than IOTF and CDC references for assessment of overweight and obesity in Chinesechildren.
