This paper investigates the dynamic relationship between poverty histories and self-rated health trajectories. We are interested in patterns of change in individuals' health over time and the ways in which such patterns are structured by continuity and change in poverty experiences. Data, collected for adults aged 25 and older in 1984 (N = 7,258), are from the 1968-1996 annual waves of Panel Study of Income Dynamics (PSID). Individual growth curves allow us to investigate health trajectories as continuous processes, as well as individual and group heterogeneity in these trajectories. We find that, on average, health deteriorates slowly over time, but there is significant variation in health in 1984 and the rate at which health declines. Histories of poverty partly accounted for the sources of individual differences in self-rated health in 1984, but they were not related to health change over time. Although increasing incomes were better for self-rated health than falling incomes, current economic circumstances did not erase the health effects of earlier poverty experiences.
本文研究了贫困经历与自评健康轨迹之间的动态关系。我们关注个体健康随时间的变化模式，以及这些模式如何由贫困经历的连续性和变化所构建。数据来自1968 - 1996年《收入动态面板研究》（PSID）的年度调查，样本为1984年25岁及以上的成年人（N = 7258）。个体生长曲线使我们能够将健康轨迹视为连续过程进行研究，同时也能研究这些轨迹中的个体和群体异质性。我们发现，平均而言，健康状况随时间缓慢恶化，但1984年的健康状况以及健康下降的速度存在显著差异。贫困经历在一定程度上解释了1984年个体自评健康差异的来源，但它们与健康随时间的变化无关。虽然收入增加对自评健康的影响优于收入下降，但当前的经济状况并未消除早期贫困经历对健康的影响。
