我国农村居民不同社会经济地位群体之间的健康差距

目的：考察我国农村居民不同社会经济地位群体之间的健康差距。资料与方法：主要依据全国31个省份2003—2006年农村固定观察点数据,计算不同社会经济地位群体的组间健康集中指数。结果：在我国农村居民中,社会经济地位较好的人群在健康方面享有优势;不同收入组间的健康不平等程度大于不同教育程度组间的健康不平等程度;收入较低和受教育程度较高的人群更容易患上慢性病。讨论：自评健康与收入的相关性要强于其与教育的相关性;受教育程度高的人群更容易患上慢性病,其原因可能与缺乏身体锻炼有关。结论：在我国农村居民中,不同社会经济地位群体间确实存在系统性的健康差异,但这种差异小于个体间的健康差异。

Health disparity between different socioeconomic groups in Chinese rural residents

Objective：To estimate health inequality between different socioeconomic groups among Chinese rural residents.Data and method：Mainly based on data collected from rural fixed watch points in 31 provinces of China from 2003 to 2006,we calculated concentration indices between different socioeconomic groups.Results：In Chinese rural residents,health inequality is in favor of groups with high socioeconomic status;health inequality between different income groups is greater than that between different educational groups;low-income and highly educated groups are at higher risks to suffer from chronic diseases.Discussion：Self-assessed health status is more strongly associated with income than with education;the fact that higher-educated groups are more inclined to suffer from chronic diseases is probably resulted from lack of physical exercises.Conclusion：It does systematically existing cross-group health inequality among rural residents in China,however it is smaller than health inequality among individuals.
