Systematic Review of 102 Cohorts Links Childhood Socioeconomic Disadvantage to 26% Higher Adult Mortality
Meta-analysis of 8.5 million adults shows childhood socioeconomic position predicts adult death rates with a 26% excess for paternal occupational disadvantage. Observational design and bias limit causal claims; mediation through adult circumstances is plausible but unquantified. Higher-quality natural experiments are needed before attributing longevity gaps directly to early conditions.
Next required evidence includes sibling or adoption designs that isolate early environment from genetic and family confounders, plus RCTs of cash-transfer or housing interventions with mortality endpoints. Without these, policy extrapolation remains limited to associative patterns rather than causal targets.
WHO: By 2035, no high-income country will achieve >10% narrowing of adult mortality gaps attributable to measured childhood disadvantage without targeted early interventions.
