No Children or 5+ Children Linked to Faster Aging in Finnish Study
TL;DR
A Finnish study of 14,836 women from the Finnish Twin Cohort finds that those who had five or more children, or none at all, aged biologically faster and had shorter lifespans than those with one to four children, suggesting a U‑shaped link between reproduction and aging. Researchers caution that the historical, Finland-specific cohort (born 1880–1957) may limit applicability to today’s contexts, and that social factors and health histories likely influence aging alongside biology.
