摘要
本文利用2008年中国亚健康调查数据并拟合多分类Logistic模型,旨在分析社会经济地位对于居民肥胖的影响。研究发现,个人教育和收入水平对于肥胖的影响在城乡、性别之间呈现出不同的模式。总体上,我国肥胖问题集中于城市男性和农村女性。收入与肥胖的关系存在明显的非线性特征,在高、中、低三等收入群体中,中等收入者肥胖风险最高。进一步分性别与城乡的分析显示,男性、农村居民的肥胖问题与收入的关联性更强,高收入者比低收入者具有更高的肥胖风险;但在女性与城市居民中,高收入与肥胖之间并不存在显著相关。此外,教育与肥胖的关系在不同性别群体中正好相反,其中男性为正相关,女性则为负相关。这些研究发现对于理解我国肥胖问题发生的社会机制、遏制肥胖病蔓延具有重要的启示意义。
By drawing data from the 2008 China Suboptimal Health Survey and estimating multinomial logit models, this study examines the relationship between socio-economic status and obesity. The main results show that, firstly, in general, urban males and rural females are the most vulnerable to obesity nowadays in China. The relationship between income and obesity is nonlinear, and the highest chance of being obese occurs to people with middle income instead of the highest income group. Yet a much more positive connection between income and obesity is observed among males and rural residents, to whom the highest income group is more likely to be obese, while this relationship is statistically insignificant among females and urban residents. Moreover, the association between education and obesity is in contradictory direction between men and women, with the former being positive and the latter being negative. These findings are helpful for us to better understand the social mechanisms that drive the occurrence of obesity in China.
