General and oral health inequalities among older Japanese : social epidemiology using multilevel analyses.

在更不平等的社会中，社会资本的侵蚀是收入不平等与健康之间联系的一种机制。然而，关于这一关系的多层次研究相对较少。收入不平等与较差的牙齿状况显著相关，与较差的自我评估健康状况略有关联。社会资本部分解释了收入不平等和自我评估健康之间的关联，但并不影响收入不平等和牙齿状况之间的强烈关联。

The erosion of social capital in more unequal societies is one mechanism for the association between income inequality and health. However, there are relatively few multi-level studies on this relation. Income inequality was significantly associated with poor dental status and marginally significantly associated with poor self-rated health. Social capital partially accounted for the association between income inequality and self-rated health but did not affect the strong association of income inequality and dental status.
