Genes Confound Education–Health Links

Updated: 2025.10.07 3M ago 2 sources
Genome-wide analysis in the Health and Retirement Study finds that education, depression, and self‑rated health share common genetic influences, while education and BMI do not. This means part of the apparent health benefit of schooling reflects genetic overlap, not only schooling’s causal impact. — It urges caution in using education as a health lever and calls for designs that separate causation from genetic correlation in social policy.

HRS GCTA estimates: education h2≈0.33, depression h2≈0.19, self‑rated health h2≈0.18, BMI h2≈0.43; evidence of genetic correlation for education–depression and education–self‑rated health, but not for education–BMI.

This Nature Communications paper directly supplies the empirical basis behind that idea: using multiple family‑based and genotype methods, the authors show substantial genetic contributions to education and occupational prestige and shared‑family effects for wealth — precisely the pattern that can create genetic covariance between schooling and health outcomes and therefore confound simple causal claims.
