目的了解长沙市与北京市和安徽省(包括合肥、宿州、黄山三个城市)青少年腰围正常参考值的差异。方法采用随机整群抽样的方法抽取长沙市四所学校,以参加2005年学生体质与健康调研的2 490名(男1 293名,女1 197名)12～17岁中学生为研究对象,测量腰围,并计算各年龄组男女学生的腰围均数和标准差。并将通过收集国家知识基础设施(CNKI)中国期刊网发表的北京市和安徽省同种族人群的腰围参考值资料与长沙市人群比较,进行分类整理和分析。结果三个地区12～17岁男女生腰围参考值拟合曲线,都显示出随年龄逐渐增长的趋势;三个地区男生的腰围参考值拟合曲线增长趋势基本一致,以长沙市男生腰围值最高,安徽省最低;三个地区女生的腰围参考值拟合曲线,在13岁之前,以长沙女生的腰围值最高,13岁之后以北京最高;安徽男女生的腰围参考曲线显著低于长沙和北京。结论中国不同地区同种族12～17岁人群腰围参考值曲线存在地域差异。
Objective To understand the differences of the normal reference values of waist circumference between adolescents in Changsha and Beijing and Anhui Provinces (including Hefei, Suzhou and Huangshan). Methods A total of 4 490 schools in Changsha city were recruited by random cluster sampling method. Among 2 490 (1293 males and 1197 females) 12-17-year-old middle school students participating in the 2005 Physical Fitness and Health Survey, , And calculate the mean and standard deviation of waist circumference for male and female students in each age group. The data of waistline reference value of the same-ethnic population in Beijing and Anhui Province published by China National Journal Network of China Knowledge Infrastructure (CNKI) were compared with those in Changsha City for classification and analysis. Results The fitting curve of waist circumference reference values for boys and girls aged 12 to 17 in three regions all showed a trend of increasing with age. The fitting curve of waistline reference values of boys in the three regions was basically the same. The waist circumference of boys in Changsha was the highest , The lowest in Anhui Province; waist circumference reference value fitting curve for girls in three regions, before the age of 13, the waistline value of Changsha girls was the highest, the highest in Beijing after 13 years old; the waistline reference curves of boys and girls in Anhui were significantly lower than those of Changsha and Beijing . Conclusion There are regional differences in the reference curve of waist circumference among different age groups in China.
