肥胖儿童生活方式的研究

Study about the lifestyle of children with obesity

目的研究我国学龄儿童中肥胖的发病率以及相关生活方式对肥胖发病的影响。方法数据来源于2005年11-12月在我国进行的一项学龄儿童睡眠相关问题的普查。选取与生活方式相关因素,主要包括:饮食方面,屏幕暴露,生活质量以及体育活动四大方面,并进行多因素Logistic回归。结果我国儿童肥胖的发病率大约为10.2%,经过单因素分析得出学龄儿童与肥胖有关的生活方式包括社交少,长期屏幕暴露,经常被师长责骂,运动少,咖啡因摄入过多。最终模型中,各方面的OR值(95%CI)分别为:长时间电视屏幕暴露1.104(1.035~1.178),经常被老师责骂1.099(1.036~1.166),较少的体育运动1.096(1.050~1.143)和朋友很少1.091(1.044~1.141)。结论在我国部分肥胖学龄儿童中存在不良的生活方式,家长应予以足够的重视。对未患肥胖的儿童也应避免出现这些情况。

Methods Data were from a sleep survey conducted from November to December in 2005. Lifestyle like eating habits, screen viewing,quality of life, and physical sports were included in our analysis, and Logistic regression analysis was used. Results The general prevalence of obesity in Chinese children was about 10.2 %. And univariate Logistical regression showed that the related factors included less friends,long time screen vie- wing, being blamed by teachers and parents, less physical sport, more caffeine intake. Multivariate Logistic analysis indicated long time screen viewing （OR=I. 104,95%CI：1. 035-1. 178）,being blamed by teachers （OR= 1. 099,95%CI：1. 036- 1. 166）,less physical sports （OR= 1. 096,95 % CI： 1. 050 ~ 1. 143） and less friends （OR = 1. 091,95 % CI： 1. 044 - 1. 141 ） were the risk factors of childhood obesity. Conclusions Parents should pay more attention to the bad lifestyles of the obese Chinese children, and try to avoid these situations.
