Greater income inequality is associated with higher prevalence of mental illness and drug misuse in rich societies. There are threefold differences in the proportion of the population suffering from mental illness between more and less equal countries. This relationship is most likely mediated by the impact of inequality on the quality of social relationships and the scale of status differentiation in different societies.
收入不平等程度较大的富裕社会中,精神疾病和药物滥用的患病率较高。在精神疾病患者比例方面,较为不平等的国家和不太不平等的国家之间存在三倍的差异。这种关系很可能是通过不平等对社会关系质量和不同社会中地位差异程度的影响来调节的。
