Abstract

Childhood psychosocial adversity is associated with accelerated onset of reproductive effort in women. Adaptive explanations for this phenomenon are built on the assumption that greater childhood psychosocial adversity is statistically associated with having a shorter period of healthy adult life during which reproduction will be possible. However, this critical assumption is never actually tested using individual-level longitudinal data. In this study, we revisit a large, longitudinally studied cohort of British women. In an earlier study, we showed that a simple index of psychosocial adversity in the first seven years of life predicted age at first pregnancy in a dose-dependent manner. Here, we show that the same index of adversity predicts accelerated deterioration of health across the potentially reproductive period, and increased levels of the inflammatory biomarker c-reactive protein at age 44. These associations are robust to controlling for adult socioeconomic position, and do not appear to be a consequence of accelerated reproductive strategy, smoking, or BMI. We argue that childhood psychosocial adversity may lead to the lasting embedding of somatic damage that accelerates age-related physical decline. This provides a compelling adaptive rationale for the accelerated reproductive schedules observed in women who experience childhood psychosocial adversity.
