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。
In this paper, we use the 2008 China Sub-Health Survey data and fit the multi-classification Logistic model to analyze the impact of socio-economic status on the residents’ obesity. The study found that the impact of personal education and income levels on obesity showed a different pattern between urban and rural areas and between sexes. In general, the problem of obesity in our country is concentrated in urban men and rural women. The relationship between income and obesity has obvious non-linear characteristics. Among the high, middle and low income groups, middle-income earners have the highest risk of obesity. Further analysis of gender and urban-rural analysis shows that male and rural residents are more likely to have a higher incidence of obesity compared with their income, while those with high income have a higher risk of obesity than low-income people. However, among women and urban residents, high income and obesity There is no significant correlation between. In addition, the relationship between education and obesity is opposite in different gender groups, of which men are positively related and women are negatively related. These findings have important implications for understanding the social mechanism of obesity in China and curbing the spread of obesity.
