Mental and physical aspects are both integral to health but little is known about the dynamic relationship between them. We consider the dynamic relationship between mental and physical health using a sample of 11,203 individuals in six waves (2002-2013) of the English Longitudinal Study of Ageing (ELSA). We estimate conditional linear and non-linear random-effects regression models to identify the effects of past physical health, measured by Activities of Daily Living (ADL), and past mental health, measured by the Centre for Epidemiological Studies Depression (CES-D) scale, on both present physical and mental health. We find that both mental and physical health are moderately state-dependent. Better past mental health increases present physical health significantly. Better past physical health has a larger effect on present mental health. Past mental health has stronger effects on present physical health than physical activity or education. It explains 2.0% of the unobserved heterogeneity in physical health. Past physical health has stronger effects on present mental health than health investments, income or education. It explains 0.4% of the unobserved heterogeneity in mental health. These cross-effects suggest that health policies aimed at specific aspects of health should consider potential spill-over effects.

老年人群身心健康的动态。


精神和身体方面都是健康不可或缺的一部分，但人们对它们之间的动态关系知之甚少。我们使用英国老龄化纵向研究 (ELSA) 六波（2002-2013 年）的 11,203 个人样本来考虑心理和身体健康之间的动态关系。我们估计条件线性和非线性随机效应回归模型，以确定过去的身体健康状况（通过日常生活活动 (ADL) 衡量）和过去的心理健康状况（通过流行病学研究抑郁症中心 (CES-D) 衡量）的影响规模，目前的身体和心理健康。我们发现心理和身体健康都适度依赖于状态。过去更好的心理健康状况会显着改善现在的身体健康状况。过去更好的身体健康对现在的心理健康有更大的影响。过去的心理健康对当前身体健康的影响比身体活动或教育的影响更大。它解释了 2.0% 的身体健康方面未观察到的异质性。过去的身体健康对当前心理健康的影响比健康投资、收入或教育的影响更大。它解释了心理健康方面 0.4% 未观察到的异质性。这些交叉效应表明，针对健康特定方面的卫生政策应考虑潜在的溢出效应。
