2012年中国7个省份10-16岁儿童青少年代谢综合征流行状况分析

Analysis of the epidemiological characteristics of metabolic syndrome among 10-16 adolescents in 7 provinces in China, 2012

目的 调查中国7个省份10-16岁儿童青少年代谢综合征流行现状.方法 采用分层整群随机抽样的方法,在广东、湖南、辽宁、上海、重庆、天津和宁夏共抽取93所中小学校,选取体格测量及其血生化指标完整的9296名10-16岁的中小学生作为研究对象.采用2010年“中国儿童青少年代谢综合征定义和防治建议”判定代谢综合征.以2010年人口普查的标准化年龄性别构成标化各省份代谢综合征检出率;采用χ^2检验比较不同特征儿童青少年学生代谢综合征检出率差异.结果 7个省份10-16岁儿童青少年代谢综合征检出率为4.1%（384/9296）,其中男生代谢综合征检出率为5.0%（237/4754）,高于女生的3.2%（147/4542）（P〈0.05）;消瘦、正常体重、超重和肥胖儿童青少年代谢综合征检出率分别为0、0.6%（39/6733）、8.9%（104/1170）和30.0%（241/803）,代谢综合征检出率随BMI的增加而升高（P〈0.001）.7个省份中,天津儿童青少年代谢综合征标化检出率最高（9.2%）,湖南最低（0.8%）.结论 我国7个省份10-16岁儿童青少年代谢综合征检出率较高;男生高于女生;超重肥胖人群高于正常体重人群;不同省份代谢综合征检出率差异较大.

Objective To investigate the prevalence of metabolic syndrome （MS） among children and adolescents aged 10-16 years old in 7 provinces in China. Methods Using the method of stratified cluster random sampling, 93 primary and secondary schools were selected from Guangdong, Hunan, Liaoning, Shanghai, Chongqing, Tianjin, and Ningxia provinces in China. A total of 9296 students aged 10-16 years old with complete physical and biochemical parameters were selected as the subjects of the present study from above 93 primary and secondary schools. MS was determined using the definition of ＂guideline of 2010 Chinese children and adolescents MS definition and treatment＂. The standardized age-sex composition of the 2010 census was used to standardize the MS detection rate of every province. Chi-square test was used to compare the difference of MS prevalence among participants with different characteristics. Results The prevalence of MS was 4.1%（384/9296） among children and adolescents aged 10-16 years old in 7 provinces in China. The prevalence of MS among males was 5.0%（237/4754）, which was significantly higher than females （3.2%） （147/4542） （P〈0.05）. Stratified by nutrition conditions, the prevalence of MS was 0, 0.6% （39/6733）, 8.9% （104/1170）, 30.0% （241/803） for thin, normal weight, overweight, and obese population, respectively. The MS prevalence increased with the increase of body mass index （BMI） （P〈0.001）. Stratified by provinces, the prevalence of MS was the highest in Tianjin （9.2%） and the lowest in Hunan province （0.8%）. Conclusion The prevalence of MS was high among children and adolescents aged 10-16 years old in 7 provinces in China. MS prevalence among males was higher than females;MS prevalence among overweight/obese population was higher than normal weight population. The detection rate of metabolic syndrome was different in different provinces.
