摘要 目的 了解西安市11~17岁青少年超重和肥胖的现状及其相关因素.方法 通过多阶段整群抽样方法抽取西安市6城区30所中学1 804名学生(11~17岁),测量其身高、体重并计算体质指数(BMI),采用2000美国疾病预防控制中心(CDC)低体重标准及中国肥胖工作组(WGOC)推荐的超重和肥胖判定标准计算低体重率、超重和肥胖率.出生体重、家庭住址、经济状况、家长学历、职业和身高、体重等信息通过家长填写问卷采集.结果 西安市青少年总超重肥胖率为17.4%(超重率11.2%、肥胖率6.2%),其中男性总超重肥胖率为20.2%,女性为14.4%.低体重率为2.7%.多元logistic回归显示:性别、年龄、家庭居住地、家庭经济状况及父母体重与青少年超重和肥胖显著相关(P<0.05).经性别、年龄调整后,城区青少年超重和肥胖的风险是郊区的2.7倍(95%可信区间1.8~4.0);家庭富裕青少年的超重和肥胖风险是不富裕家庭的1.6倍(95%可信区间1.04~2.5);父母超重或肥胖的青少年超重肥胖发病风险是父母体重正常的1.8倍(95%可信区间1.3~2.5).结论 超重和肥胖已经成为影响西安市青少年健康的一个主要公共卫生问题,多发于城区、经济富裕或父母肥胖的家庭,以男性居多. Objective To assess the magnitude of overweight and obesity and its associated sociodemographic factors in adolescents attending junior high schools in Xi'an, Shanxi province. Methods A total of 1 804 adolescents attending junior high schools in Xi'an (age: 11-17years) were enrolled randomly from 30 schools in 6 districts in Xi'an. Overweight and obesity was categorized with body mass index (BMI) cutoffs from Working Group of Obesity in China (WGOC). Underweight was defined by BMI-Z ≤-2 s. Sociodemographic information was collected from the parents of the survey participants using self-administered, structured and precoded questionnaires. Results Overall 17.4% of adolescents were overweight or obese ( overweight 11.2% ; obesity 6.2% ) , but there was a marked gender difference in the prevalence with 20. 2% of boys versus 14. 4% of the girls being overweight or obese. The prevalence of underweight was 2. 7%. In a multivariate model, age, residence, household wealth, and parents' BMI were significantly associated with overweight and obesity (P 〈 0. 05 ). After having been adjusted for age and gender, the odds ratio of an adolescent being overweight and obese was 2.7 (95% CI: 1.8-4. 0) folds higher in urban areas than in rural areas, and was 1.6 (95% adolescent themselves CI: 1.04-2.5) folds higher for adolescents with one or both parents overweight was 1.8 compared from rich families than those from poor families. An (95% CI: 1.3-2.5 ) more likely to be overweight to those with normal weight parents. Conclusions Overweight and obesity is a major public health problem in adolescents in Xi'an. Overweight and obesity is more prevalent richer families living in urban districts and those whose parents were either overweight or in younger boys from obese.
