The aim of the present study was to investigate the impact of childhood living conditions, marital status, and social class in adulthood on the risk of mortality during mid-life. Two questions were addressed: Is there an effect of childhood living conditions on mortality risk during mid-life and if so, is the effect mediated or modified by social class and/or marital status in adulthood?
A nationally representative, Swedish, level of living survey from 1968 was used as baseline. The study included those aged 25-69 at baseline (n = 4082). Social conditions in childhood and adulthood were assessed using self-reports. These individuals were then followed for 39 years using registry data on mortality.
The results showed associations between childhood living conditions, marital status, social class in adulthood and mortality during mid life. Social class and familial conditions during childhood as well as marital status and social class in adulthood all contributed to the risk of mortality during mid-life. Individuals whose father's were manual workers, who grew up in broken homes, who were unmarried, and/or were manual workers in adulthood had an increased risk of mortality during mid life. The effects of childhood conditions were, in part, both mediated and modified by social class in adulthood.
The findings of this study suggest that there are structural, social conditions experienced at different stages of the life course that affect the risk of mortality during mid-life.
本研究旨在探讨童年生活条件、婚姻状况和成年后的社会阶层对中年期死亡率的影响。提出了两个问题：童年生活条件是否会影响中年期的死亡率，以及如果是这样，这种影响是否会被成年后的社会阶层和/或婚姻状况所中介或修正？
本研究使用了 1968 年瑞典一项具有代表性的生活水平调查作为基线数据。研究对象为基线时年龄在 25-69 岁的人群（n=4082）。采用自我报告的方式评估童年和成年时期的社会条件。然后，通过死亡率登记数据对这些人进行了 39 年的随访。
研究结果显示，童年生活条件、婚姻状况、成年后的社会阶层与中年期死亡率之间存在关联。童年时期的社会阶层和家庭条件以及成年后的婚姻状况和社会阶层都增加了中年期的死亡率风险。父亲为体力劳动者、在单亲家庭中长大、未婚和/或成年后为体力劳动者的个体，其中年期的死亡率风险增加。童年时期的条件的影响部分受到成年后社会阶层的中介和修正。
本研究的结果表明，生命历程不同阶段经历的结构性社会条件会影响中年期的死亡率风险。
