目的了解北京市海淀区1985-2010年中小学生超重、肥胖及体质量指数(BMI)变化趋势,为儿童青少年肥胖干预政策的制定提供科学依据。方法使用1985-2010年中国学生体质与健康调研北京市海淀区资料,根据身高和体重计算BMI,应用中国肥胖工作组(WGOC)“中国学龄儿童青少年超重、肥胖筛查BMI分类标准”判定超重和肥胖,比较7～18岁学生各年度超重与肥胖检出率,分析各百分位数BMI(P25,P50,P75,P90,P95)变化趋势。结果 1985-2010年7～18岁男生肥胖率分别为1.0%,4.0%,6.5%,15.2%,女生分别为0.5%,2.1%,2.8%,5.2%。各年龄组男、女生超重、肥胖率以及各百分位数BMI值均随年度不断上升(P值均<0.01)。1985-2010年各百分位数BMI增长表现为男生增速高于女生,较高百分位BMI值增速高于较低百分位BMI值,各年龄组高百分位BMI值全面大幅上升。2000-2010年以来10～15岁男、女生BMI增速明显。结论北京市海淀区1985-2010年学生超重、肥胖检出率以及BMI水平持续增长,10～15岁学生是下一步肥胖防控的重点对象。
Objective To understand the trend of overweight, obesity and body mass index (BMI) among primary and secondary school students in Haidian District of Beijing from 1985 to 2010 and to provide a scientific basis for the formulation of obesity intervention policy for children and adolescents. Methods According to the data of Haidian District of Beijing from 1985 to 2010, the BMI was calculated according to the height and weight of the students. The Chinese Obesity Working Group (WGOC) and the BMI classification criteria of overweight and obesity screening among Chinese children and adolescents Overweight and obesity. The detection rates of overweight and obesity among 7 ~ 18 year-old students were compared, and the change trend of each percentile BMI (P25, P50, P75, P90, P95) was analyzed. Results The prevalence rates of obesity among boys aged 7-18 years from 1985 to 2010 were 1.0%, 4.0%, 6.5% and 15.2% respectively. The prevalence of obesity among boys was 0.5%, 2.1%, 2.8% and 5.2% respectively. The male and female overweight, obesity rates and the percentiles of BMI in all age groups increased year by year (P <0.01). Growth Per Capita BMI in 1985-2010 The performance of boys was higher than that of girls, and the BMI of higher percentiles increased faster than the lower percentile of BMI. The BMI of the high percentiles of each age group was significantly higher rise. Since 2000 - 2010 10 to 15-year-old male and female students BMI significant growth. Conclusion The prevalence of overweight, obesity and BMI in students from 1985 to 2010 in Haidian District, Beijing continued to increase. Students aged 10 to 15 years are the focus of obesity prevention and control in the next step.
