This study draws on longitudinal data from the Health and Retirement Study (2008–2020) to investigate the dynamic bidirectional relationship between physical and mental health, focusing on socioeconomic disparities. Dynamic panel models reveal significant bidirectional associations between measures of physical and mental health for both positive and negative health indicators, but the magnitude varies by education and wealth. Specifically, the interconnection between indicators of negative physical and mental health (i.e., functional limitations and depression symptoms) is stronger among the socioeconomically disadvantaged, whereas the relationship between indicators of positive physical and mental health (i.e., physical activity and positive affect) is stronger at higher levels of wealth (although not education). By disentangling the bidirectional association between physical and mental health, these results imply an important process of the reproduction and perpetuation of health inequalities.

不平等循环：社会经济地位和身心健康之间的动态双向关系


本研究利用健康与退休研究（2008-2020 年）的纵向数据来调查身心健康之间的动态双向关系，重点关注社会经济差异。动态面板模型揭示了积极和消极健康指标的身心健康指标之间显着的双向关联，但幅度因教育和财富而异。具体来说，消极身心健康指标（即功能受限和抑郁症状）之间的相互联系在社会经济弱势群体中更强，而积极身心健康指标（即身体活动和积极影响）之间的关系在财富水平较高（尽管不是教育）中更强。通过解开身心健康之间的双向关联，这些结果意味着健康不平等的复制和延续的一个重要过程。
