中国成年人超重肥胖影响因素meta分析

Influencing factors of overweight and obesity among Chinese adults: a meta-analysis

目的 定量评价近年来中国成年人超重肥胖的影响因素。方法 在Pub Med、CNKI、万方数据库中进行文献检索,收集2010—2014年3月公开发表的关于中国成年人超重肥胖影响因素的调查研究。采用Rev Man5.1和Stata11软件进行meta分析,用固定效应模型或随机效应模型进行数据合并,计算OR值和95%CI。用Begg秩相关和漏斗图来判定发表偏倚。结果 共纳入的19篇文献,包括95 798名调查者,影响因素合并的OR及95%CI分别为：高脂饮食1.37（1.17~1.59）、饮酒1.12（1.03~1.22）、年龄1.03（1.01~1.05）、吸烟0.72（0.67~0.77）、运动0.79（0.63~0.98）,且均具有统计学意义。结论 高脂饮食、饮酒和年龄是中国成年人超重肥胖的危险因素,运动、吸烟是其保护性因素。

Objective To evaluate influencing factors of overweight and obesity among adult populations in China. Methods Studies on impact factors of overweight and obesity among Chinese adult populations published from 2010 to 2014 were searched through PubMed, CNKI and Wanfang database and analyzed with RevMan 5.1 and Stata 11. The data collected were combined using fixed and random effect model and the odds ratio（OR） and its 95% confidence interval （95% CI）were calculated. Begg rank correlation and funnel plot were adopted in the estimation of publishing bias. Results A total of 19 researches （95 798 adult participants）were included in the study. The significant overweight/ obesity related factors were high-fat diet, alcohol drinking, age, smoking, and physical exercise, with the combined ORs （95 % CI） of 1.37 （ 1.17,1.59 ）, 1.12 （ 1.03,1.22 ）, 1.03 （ 1.01,1.05 ）, 0. 72 （ 0. 67,0. 77 ）, and 0. 79 （ 0. 63,0. 98 ）, respectively. Conclusion High-fat diet, alcohol drinking, and age are risk factors, while smoking and physical exercise are protective factors for overweight and obesity among Chinese adults.
