本文利用瑞典南部高质量的历史微观数据，分析了生育史对已婚男性和女性晚年死亡率的影响。该分析使用 Cox 比例风险模型，估计出生次数以及第一次和最后一次生育时间对老年死亡率的影响。通过研究不同性别和社会地位的先前生育对死亡率的影响，我们还获得了有关生育与老年死亡率的机制的重要见解。结果表明，生育孩子的数量对女性 50 岁以后的寿命有统计学上显着的负面影响，但对男性则没有影响。按社会群体进行的分析表明，只有无地妇女因生育更多孩子而死亡率较高，这似乎表明，主要的解释是女性特有的社会或经济条件，而不是生育的严格生物或生理效应。
This paper presents an analysis of the impact of childbearing history on later-life mortality for ever-married men and women using historical micro-level data of high quality for southern Sweden. The analysis uses a Cox proportional hazards model, estimating the effects on old-age mortality of number of births and timing of first and last births. By studying the effects of previous childbearing on mortality by sex and social status, we also gain important insights into the mechanisms relating childbearing to mortality in old age. The results show that number of children ever born had a statistically significant negative impact on longevity after age 50 for females but not for mates. Analysis by social group shows that only landless women experienced higher mortality from having more children, which seems to indicate that the main explanations are to be found in social or economic conditions specific to females, rather than in the strictly biological or physiological effects of childbearing.
