Abstract:

Objective    To investigate the distribution characteristics of the detection rate of short stature in primary and middle school students in Anhui province. Methods    A total of 12009 urban and rural primary and middle school students aged from 7 to 19 years in 3 areas （Suzhou，Hefei，Chizhou） in Anhui province from September 2014 to November 2014 were recruited. Body heights were measured using the national standard，and the detection rate of short stature was calculated. Results    The detection rate of short stature in primary and middle school students in Anhui province among all age groups was 3.16%； the detection rate of short stature in rural area was 3.75%，and in urban area 2.56%，which was significantly lower in urban area than that in rural area（χ2＝13.731，P＜0.001）. The detection rate of short stature in boys was 3.05%，in girls 3.28%，and no obvious difference was found of the detection rate of short stature between boys and girls（χ2＝0.517，P＞0.05）. The detection rate of short stature in boys and girls in urban areas was 2.53%and 2.60% respectively，while the rate in rural area was 3.56%and 3.93% respectively. Conclusion    The average detection rate of short stature in the primary and middle school students in Anhui province is 3.16%；the rate is significantly higher in rural area than in urban area；there is no obvious difference in the detection rate of short stature between boys and girls.

摘要：

目的    研究安徽省城乡中小学生矮身材分布特点。方法    2014年9月至11个月采用分层整群抽样抽取安徽省3个地区（宿州市、合肥市、池州市）的城乡中小学生，调查7～19岁共12 009名中小学生的身高，分析矮身材分布特点。结果    安徽省中小学生各年龄组总体矮身材的检出率为3.16%，乡村矮身材的检出率高于城市（3.75% vs. 2.56%，χ2＝13.731，P＜0.001）。男女矮身材检出率差异无统计学意义（3.05% vs. 3.28%，χ2＝0.517，P＞0.05）。男、女矮身材检出率在城市分别为2.53%、2.60%，在乡村分别为3.56%、3.93%。结论    安徽省城乡中小学生抽样平均矮身材检出率为3.16%，乡村抽样中小学生矮身材检出率高于城市；男女矮身材检出率差异无统计学意义。
