Together in sickness and in health: Spillover of physical, mental, and cognitive health among older English couples
利用英国老龄化纵向研究数据，分析50岁以上已婚夫妻在身体、心理和认知健康上的跨领域和跨配偶溢出效应，发现记忆与行动能力、抑郁与行动能力之间存在双向溢出，且配偶健康对男女心理健康的影响存在性别差异。
Using data from eight waves of the English Longitudinal Study of Aging, we study the cross-domain and cross-spouse spillover of health among married adults aged 50 and above in England. We apply the system generalized method of moments to linear dynamic panel models for physical, mental, and cognitive health, controlling for individual heterogeneity and the influence of marriage market matching and shared environments. Our findings reveal bidirectional spillovers between memory abilities and mobility difficulty among men, as well as between depressive symptoms and mobility difficulty among women. Worsening mobility increases the risk of depression in men, but not vice versa. Additionally, gender-specific cross-spouse effects are observed. Women's mental health is significantly influenced by their spouse's mental health, while this effect is weaker for men. Conversely, men's mental health is notably affected by their spouse's physical health. These results highlight the importance of considering spillovers within families and across health domains when developing policies to promote health and reduce health disparities among the elderly population.
