【目的】 调查温州城乡中小学生超重肥胖的患病状况。 【方法】 2011年5-8月随机抽取温州城区、城乡结合部及农村中小学共9所学校进行整群调查。记录学生的一般资料,同时测量身高体重两项发育指标,计算体质指数,按照2004年中国肥胖问题工作组(WGOC)推荐的诊断标准,评价温州市中小学生的超重及肥胖患病状况。 【结果】 共9 657名在校学生参与调查,其中男生5 114 名,女生4 543名,平均年龄(14.95±4.53)岁,被调查人群中超重占7.6%,肥胖占2.6%,男生超重和肥胖患病状况均显著高于女生(9.8% vs 5.2%,5.2% vs 1.2%,P值均<0.01),各年龄段中以7岁儿童肥胖及超重状况最为严重(27.15% vs 7.955%),城区及城乡结合部超重肥胖患病状况明显高于农村(P值均<0.01)。 【结论】 温州中小学校肥胖和超重总患病约为10%,男性,尤其是城区及城乡结合部男生超重肥胖患病情况最为严重,需要引起高度重视。

【Objective】 To investigate the prevalence of the overweight and obesity among primary and middle school students in Wenzhou. 【Methods】 Samples were collected from randomly selected nine primary and middle schools in urban,suburban,and rural areas of Wenzhou city from May 1st to Aug.31th 2011.Anthropometric data of these students were obtained.Height and weight were measured and the body mass index (BMI) was calculated.BMI classification reference proposed by Working Group on Obesity in China (WGOC) 2004 used as screening reference to calculate the prevalence and trends of overweight/obesity in these students. 【Results】 Totally 9 657 students in primary and middle schools were recruited in current study,among which 5 114 were boys and 4 543 were girls.The median age was 12.5 years,ranged from 7 to 18 years old.The overall prevalence of overweight and obesity were 7.6% and 2.6% respectively.The prevalence of overweight and obesity in male students were significantly higher than in female students (9.8% vs 5.2%,5.2% vs 1.2% respectively,P<0.01).Among different age groups,the prevalence of obesity and overweight in 7 year old students was the highest(27.15% vs 7.955%).The prevalence of obesity and overweight in urban and suburban areas was significantly higher than rural areas P<0.01. 【Conclusions】 In contrast to most developed countries,the prevalence of overweight and obesity in the primary and middle schools was about 10% in Wenzhou.Intervention and strategies for obesity prevention should be targeting families in urban and urban-rural areas,perhaps with particular focus on boys.
