Childhood socioeconomic conditions tied to adult mortality risk
A systematic review of 102 long-term studies covering about 8.5 million people in 24 countries found that childhood disadvantage was associated with higher death rates in adulthood. Across 474 comparisons, more than eight in ten showed worse adult mortality among those who grew up with greater socioeconomic disadvantage. The largest evidence base involved fathers' occupations, reflecting how mid-20th-century research often measured household social position.
The review covered 102 studies from 24 countries, involving roughly 8.5 million people. In 474 comparisons, over 80% linked greater childhood socioeconomic disadvantage to higher adult mortality. The strongest evidence involved fathers’ jobs, a common mid-20th-century stand-in for a family’s social standing; mothers’ work was seldom recorded, leaving family circumstances only partly captured.
When 18 studies were pooled, adults whose fathers held the least advantaged jobs had about a 26% higher death rate than those whose fathers held the most advantaged jobs. Links appeared for cardiovascular disease, respiratory disease, and lung cancer. Parental education, financial hardship, and crowded housing also pointed to higher later mortality, though based on fewer studies.
This evidence could encourage health services and researchers to consider childhood circumstances alongside adult risk factors when studying longevity. People who grew up with lower parental education, financial strain, or crowded housing may face higher later mortality risks, though observational data cannot establish cause. The findings may also prompt broader discussion about how early-life conditions shape lifelong health inequalities, without implying that any single intervention would necessarily close those gaps.
