目的分析中小学生单纯性肥胖的影响因素,为探讨干预对策提供依据。方法采取多阶段分层整群抽样,于2008年4-10月对江苏省徐州市10所中小学学生进行问卷调查及体检,调查学生进食行为、饮食习惯、生活运动行为、家庭生活和饮食活动状况等,采用非条件Logistic回归方法分析影响肥胖因素。结果出生体重(OR=1.357,P<0.05)、父亲文化程度高(OR=2.048,P<0.05)、进食速度快(OR=1.747,P<0.05)、喜欢吃肉(OR=3.451,P<0.05)和甜食(OR=1.379,P<0.05)为危险因素;喜欢吃鸡蛋(OR=0.628,P<0.05)、豆制品(OR=0.699,P<0.05)、新鲜蔬菜水果(OR=0.346,P<0.05)、营养补充剂(OR=0.354,P<0.05)和体育锻炼次数多(OR=0.344,P<0.05)及时间长(OR=0.381,P<0.05)为保护因素。结论徐州市中小学生单纯性肥胖应从饮食、生活行为习惯、家长认识、家庭环境等方面予以干预,应从学校、社区、家庭着手加强健康教育宣传等。

Objective To analyze the factors of simple obesity in primary and middle school students in order to provide basis for intervention. Methods Using multi-stage stratified cluster sampling, students in 10 primary and middle schools were selected. The questionnaire survey was conducted among the students to collect information on diet, exercise and other living behavior and physical examination was carried out. Non-conditional Logistic regression was used to analyze factors of obesity. Results High-birth-weight （ OR = 1. 357, P 〈 0. 05 ）, high education level of the father （ OR = 2. 048, P 〈 0.05 ）, eating fast （ OR = 1. 747, P 〈 0. 05 ）, enjoy meat （ OR = 3.451, P 〈 0.05 ） and sweets （ OR = 1.379, P 〈 0. 05 ） were risk factors of obesity. Consumption of eggs（ OR =0. 628 ,P 〈0. 05） ,taking soy products（ OR =0. 699,P 〈0. 05） ,taking fresh fruits and vegetables （ OR = 0. 346, P 〈 0. 05 ）, nutritional supplements （ OR = 0. 354, P 〈 0. 05 ）, more physical exercise（ OR = 0. 344 ,P 〈 0. 05 ） and long time exercise were protective factors of normal weight.
