 PNAS 2026 cohort analysis shows the deaths-of-despair framing is incomplete: post-1970 US birth cohorts show mortality deterioration not just in external causes (overdoses, suicide) but also in cardiovascular disease and cancer simultaneously. The problem is multi-causal across all three major cause categories, not primarily driven by external causes.

+Food insecurity functions as a co-mechanism in the deaths of despair pathway. CARDIA study shows 41% elevated CVD risk from food insecurity in young adulthood, independent of income/education, suggesting nutritional pathways (not just economic deprivation) drive cardiovascular mortality in economically damaged populations.

+Northwestern Medicine researchers recommend integrating food insecurity screening into clinical CVD risk assessment based on CARDIA evidence showing 41% elevated risk. This creates a specific clinical use case for SDOH screening with clear downstream disease prevention rationale, potentially strengthening the case for Z-code adoption in cardiology.

+CARDIA prospective cohort (N=3,616, 20-year follow-up) shows food insecurity at age 40 predicts 41% higher CVD incidence by age 60, with effect persisting after adjustment for income and education. This establishes temporality: food insecurity → CVD, not just correlation. The mechanism likely operates through the UPF-inflammation-hypertension pathway since the effect is independent of general socioeconomic status.

+# Food insecurity in young adulthood independently predicts 41% higher CVD incidence in midlife after adjustment for socioeconomic factors, establishing temporality for the SDOH → cardiovascular disease pathway
+
+The CARDIA prospective cohort study followed 3,616 US adults without preexisting CVD from 2000 to 2020 (mean baseline age 40.1 years, 56% female, 47% Black). Food insecurity at baseline was associated with HR 1.41 for incident CVD after adjustment for income, education, and employment. This is the first prospective study establishing temporality—food insecurity comes first, CVD follows 20 years later. Prior studies were cross-sectional and could not distinguish whether food insecurity caused CVD or whether CVD-related disability caused food insecurity. The persistence of the association after socioeconomic adjustment suggests food insecurity operates through specific nutritional pathways (likely the UPF-inflammation-hypertension chain documented in Session 16) rather than only through general poverty effects. The 47% Black composition addresses the population most affected by both food insecurity and CVD disparities. Authors recommend integrating food insecurity screening into clinical CVD risk assessment, stating 'If we address food insecurity early, we may be able to reduce the burden of heart disease later.' This provides the upstream causal evidence that the entire food-environment thread has been building toward.

 EXTRACTION HINT: Extract as standalone claim: "Food insecurity in young adulthood independently predicts 41% higher CVD incidence in midlife, establishing temporality for the SDOH → cardiovascular disease pathway." Keep scope narrow — prospective in a specific cohort, not a systematic claim about all SDOH. Note the 47% Black composition and adjusted analysis.
