目的了解中国学龄儿童腰围正常值,为建立中国学龄儿童青少年超重/肥胖筛查标准提供依据。方法以2008年全国学生体质健康监测15省市区14.6万余名7～18岁汉族中小学生为参照人群,以LMS法建立腰围正常值。结果获得中国7～18岁汉族中小学生各年龄组男女腰围P3,P5,P10,P15,P25,P50,P75,P85,P90,P95和P97百分位数正常值及其LMS曲线。结论利用腰围正常值可在经疾病危险因素验证后建立腰围筛查超重、肥胖界值点的标准,并就验证过程一些必要的步骤和方法提出建议。
Objective To understand the normal waistline of Chinese school-age children and provide the basis for establishing the Chinese screening criteria for overweight / obesity in school-age children. Methods Based on 2008 National Health Fitness Monitoring for Students across 156 provinces and municipalities, 146,000 Han students from 7 to 18 years old were enrolled in this study. The waist circumference was normalized by LMS. Results The normal values of percentiles of P3, P5, P10, P15, P25, P50, P75, P85, P90, P95 and P97 and their LMS curves in different age groups of Chinese children aged 7-18 years were obtained. Conclusion The use of normal waist circumference can establish a standard for waist circumference screening of overweight and obesity thresholds after verification of disease risk factors and make recommendations on some necessary steps and methods of the validation process.
