Density-dependent and extrinsic mortality are predicted to accelerate reproductive maturation. The first 5 years of life is a proposed sensitive period for life-history regulation. This study examines the ways in which local mortality during this sensitive period was related to subsequent marriage timing in nineteenth-century Belgium ( women = 11 892; men = 14 140). Local mortality during the sensitive period was inversely associated with age at first marriage for men and women controlling for literacy, occupational status, population growth and migration. Cox regression indicated decreased time to marriage for women (HR = 1.661, 95% CI: 1.542-1.789) and men (HR = 1.327, 95% CI: 1.238-1.422) from high mortality municipalities. Rising population growth rates were associated with earlier marriage for men and women. Migration in general was associated with later marriage for men and women. Consistent with life-history predictions, harsh ecological conditions during early life such as famine coincided with earlier marriage.
密度依赖和外在死亡率预计会加速生殖成熟。生命史调节的敏感时期是生命的前五年。本研究考察了在这一敏感时期，当地死亡率与 19 世纪比利时随后的婚姻时间之间的关系（女性=11892；男性=14140）。在控制了文化程度、职业地位、人口增长和移民等因素后，敏感时期的当地死亡率与男女的初婚年龄呈反比关系。Cox 回归表明，女性（HR=1.661，95%CI：1.542-1.789）和男性（HR=1.327，95%CI：1.238-1.422）的结婚时间因高死亡率城市而缩短。人口增长率的上升与男女结婚年龄提前有关。一般来说，男性和女性的迁移都与晚婚有关。与生命史预测一致的是，生命早期如饥荒等恶劣的生态条件与早婚有关。
