没有以前的调查认为状态依赖和未观察到的异质性之间的关系定期体力活动（RPA）和潜在的健康股票（LHS）的影响。考虑到国家的依赖性，纠正了对社会经济因素影响的可能高估。我们估计了中年日本工人的RPA和LHS的国家依赖程度。本研究所用的5年纵向数据来自中老年人纵向调查。RPA和LHS均存在个体异质性，动态随机效应概率单位模型提供了最佳规范。吸烟习惯、低教育程度、较长的工作时间和较长的通勤时间对RPA参与有负面影响。考虑到与其他生活方式变量混淆的可能性，RPA对LHS有积极影响。LHS的状态依赖程度为正且显著。增加RPA的强度对LHS有积极的影响，并导致RPA的个人表现出更大的持久性LHS相比，没有RPA的个人。这一结果表明，促进RPA的政策干预，如戒烟，具有持久的影响。我们的结论是，戒烟是一个重要的健康政策，以增加参与RPA和LHS。
No prior investigation has considered the effects of state dependence and unobserved heterogeneity on the relationship between regular physical activity (RPA) and latent health stock (LHS). Accounting for state dependence corrects the possible overestimation of the impact of socioeconomic factors. We estimated the degree of the state dependence of RPA and LHS among middle-aged Japanese workers. The 5 years’ longitudinal data used in this study were taken from the Longitudinal Survey of Middle and Elderly Persons. Individual heterogeneity was found for both RPA and LHS, and the dynamic random-effects probit model provided the best specification. A smoking habit, low educational attainment, longer work hours, and longer commuting time had negative effects on RPA participation. RPA had positive effects on LHS, taking into consideration the possibility of confounding with other lifestyle variables. The degree of state dependence of LHS was positive and significant. Increasing the intensity of RPA had positive effects on LHS and caused individuals with RPA to exhibit greater persistence of LHS compared to individuals without RPA. This result implies that policy interventions that promote RPA, such as smoking cessation, have lasting consequences. We concluded that smoking cessation is an important health policy to increase both the participation in RPA and LHS.
