目的调查佛山地区7~17岁青少年儿童超重及肥胖的检出率及分布情况,分析相关影响因素。方法采用多阶段分层随机抽样方法抽取南海区2个街道6个镇共17 124户中7~17岁常住居民进行调查。采用入户面对面访谈的方法,并进行相关人体测量。采用中国肥胖问题工作组青少年超重肥胖标准计算超重肥胖检出率,用SPSS13.0统计软件进行多因素Logistic回归分析,查找青少年儿童超重肥胖的相关影响因素。结果佛山地区青少年儿童体重指数均值为(18.26±3.14),超重、肥胖的检出率分别为7.9%、4.5%。男女生超重、肥胖检出率分别为10.1%、5.1%和5.3%、3.7%,差异均有统计学意义(P<0.05)。多因素Logistic回归显示,与7~10岁儿童相比,13岁以上各年龄组超重肥胖的风险均明显下降,OR值分别为0.370、0.264,P均<0.01。其他包括性别0.544(0.443~0.668)、挑食0.692(0.560~0.857)、每天刷牙0.560(0.315~0.994)、每天玩电脑看电视时间1.398(1.007~1.942)及睡眠状况0.494(0.352~0.695)是青少年超重肥胖的影响因素。结论佛山地区青少年儿童超重肥胖率超过全国平均水平,成为严重的公共卫生问题,应以7~13岁儿童作为重点人群,通过改善饮食习惯和行为生活方式,加强体育锻炼等防治措施控制和降低超重肥胖的发生率。
Objective To investigate the prevalence and distribution of overweight and obesity among 7-17-year-old adolescent children in Foshan area and analyze the related factors.

Adopt face-to-face interviewing method and carry out relevant anthropometry. The prevalence of overweight and obesity was calculated using the standard of overweight and obesity adolescent in China’s Obese Working Group. Multivariate Logistic regression analysis was performed with SPSS13.0 statistical software to find out the influencing factors of overweight and obesity among adolescent children. Results The mean body mass index of young children in Foshan was (18.26 ± 3.14). The detection rates of overweight and obesity were 7.9% and 4.5% respectively. The detection rates of overweight and obesity in boys and girls were 10.1%, 5.1%, 5.3% and 3.7%, respectively, with significant differences (P <0.05). Multivariate logistic regression showed that the risk of overweight and obesity in all age groups over 13 years old was significantly lower than that of children aged 7-10 years (OR = 0.370,0.264, P <0.01). Others included sex 0.543 (0.443-0.668), picky eaters 0.692 (0.560-0.857), teeth brushing 0.560 (0.315-0.994) a day, watching TV time 1.398 (1.007-1.992) and sleeping status 0.494 (0.352-0.695) per day for teens Influencing factors of overweight and obesity.
