目的了解马鞍山市初三学生中心性肥胖状况及其影响因素,为采取有效的预防干预措施提供依据。方法整群抽取马鞍山市10所中学,采用问卷调查和人体测量相结合的方法,获取初三学生社会人口统计学变量和身高、体重、腰围、臀围等形态发育指标,对中心性肥胖状况及其影响因素进行分析。结果肥胖、中心性肥胖学生的检出率分别为3.8%与2.9%,男生肥胖检出率(5.1%)高于女生(2.5%),差异有统计学意义(χ2=20.830,P<0.01);男生中心性肥胖检出率(4.1%)高于女生(1.8%),差异有统计学意义(χ2=21.945,P<0.01)。多因素非条件Logistic回归分析显示,市区、自己目前体型肥胖和小学三年级体型偏胖是发生中心性肥胖的危险因素。结论马鞍山市初三学生肥胖、中心性肥胖的检出率较高,并与性别、家庭住址、体型状况等人口统计学特征和形态学特征相关联。

Male students prevalence rate（ 5.1% ） of obesity was significantly higher than female（ 2.5% } （X2 = 20. 830,P 〈 0.01 }. Male students prevalence rate （4.1% } of central obesity was significantly higher than female{ 1.8% ）{X2 = 21. 945, P 〈 0. 01 ）.
