Abstract Background Growth differentiation factor 15 (GDF15) is a crucial biomarker in various physiological and pathological processes. While elevated GDF15 levels are linked to increased mortality risk, the role of DNA methylation (DNAm)-predicted predicting has not been extensively studied. The purpose study investigate association between DNAm-predicted all-cause cardiovascular disease (CVD) nationally representative cohort. Methods Data from NHANES 1999–2002 were analyzed. estimated using regression model. Weighted multivariate Cox regressions employed assess relationship outcomes. Restricted cubic splines used explore dose-response relationships, subgroup analyses conducted enhance result reliability. Results Higher significantly associated with risk (HR = 1.08, 95% CI: 1.02–1.15). Participants highest tertile showed higher 1.56, 1.16–2.10) 2.52-fold 2.52, 1.22–5.19). Kaplan-Meier curves revealed decreasing survival probability tertiles. spline analysis demonstrated non-linear mortality. positive correlation remained robust most subgroups. Conclusions independently predicts This persists across multiple models stratified subgroups, supporting GDF15’s value as for stratification. Future research should elucidate underlying biological mechanisms evaluate clinical utility guiding reduction interventions.
