现在，人们已经很好地理解，生命过程因素影响一系列不同的结果，从一般的幸福到身体功能和慢性病。在生命过程中暴露在有利和不利的环境中，每个人都会有所不同，并将构成独特的生活暴露轨迹，这将表现为健康和幸福的不同表现。在这里，我们提出了一个生命过程对健康影响的三重模型：潜伏期、累积和路径。我们所说的潜伏期是指生命过程中某一时刻的暴露与几年或几十年后健康表现的可能性之间的关系，而不考虑干预经验。累积指的是在生命过程中多次接触对健康的影响。最后，途径代表了暴露的依赖序列，其中在生命过程的第一阶段暴露会影响在生命过程的后期发生其他暴露的概率，以及相关的表达。证明这些关系的证据表明，如果不考虑早期生活和成年生活经历，旨在改善健康状况的政策往往会忽视根本原因。
It is now well understood that life-course factors affect a diverse range of outcomes, from general well-being to physical functioning and chronic diseases. Exposure to both beneficial and adverse circumstances over the life course will vary for each individual and will constitute a unique life exposure trajectory, which will manifest as different expressions of health and well-being. Here, we present a 3-fold model of life-course influences on health: latency, cumulative, and pathway. By latency we mean relationships between an exposure at one point in the life course and the probability of health expressions years or decades later, irrespective of intervening experience. Cumulative refers to multiple exposures over the life course whose effects on health combine. Finally, pathways represent dependent sequences of exposures in which exposure at I stage of the life course influences the probability of other exposures later in the life course, as well as associated expressions. Evidence demonstrating these relationships suggests that, without a consideration of early life as well as adult life experience, policies designed to improve health status tend to overlook root causes.
