背景：很少有跨国研究比较东亚国家社会经济地位(SES)和健康之间的关系。本研究探讨了东亚四个社会--中国、日本、韩国和中国台湾地区的自测健康水平与社会经济地位的关系。方法：我们使用了2006年东亚社会调查的数据，其中包括来自四个国家的具有国家代表性的样本。以收入、教育程度、职业和阶层认同4个标准化SES指数为解释变量，对SRH进行Logistic回归分析，比较各SES指数与SRH的关联度。结果：共调查8120名20-69岁的被调查者。总体而言，在东亚社会中观察到了健康的社会梯度。在中国、韩国和台湾，四个社会经济地位指数中的三个在男性和女性群体中都显示出统计上的显著相关性。在日本，除阶级认同外，其他SES指标均未显示与SRH有显著关系。在SES指数之间的差异方面，类别认同与SRH的相关性最强，而职业类别与SRH的相关性最弱。结论：我们的研究结果表明，与其他东亚国家相比，日本的健康不平等程度较低。此外，职业类别的指数可能不足以解释东亚的健康不平等。
Background: Few cross-national studies have compared the relationship between socio-economic status (SES) and health among East Asian countries. This study elucidates the relationship between SES and self-rated health (SRH) in four societies of East Asia: China, Japan, South Korea and Taiwan. Methods: We used the data from the East Asian Social Survey 2006, which consists of nationally representative samples from each of the four countries. Logistic regression analysis of SRH was performed using four standardized SES indices (income, education, occupation and class identification) as explanatory variables to compare the degree of association of each SES index with SRH. Results: A total of 8120 respondents in the age range of 20-69 years were analysed. Overall, social gradients in health were observed in the East Asian societies. In China, South Korea and Taiwan, three of the four SES indices showed a statistically significant association for both male and female groups. In Japan, except class identification, no other SES index showed a significant relationship with SRH. With regard to the differences between the SES indices, class identification exhibited the strongest association with SRH, while occupational class displayed the weakest association. Conclusion: Our study results indicate that Japan has low levels of health inequality compared to other East Asian countries. Furthermore, an index of occupational classes may be insufficient to explain health inequalities in East Asia.
