Plant-based dietary patterns are associated with slower epigenetic aging
Associations between different types of plant-based diet indices (PDI) and epigenetic aging in the Atherosclerosis Risk in Communities Study (ARIC) and National Health and Nutrition Examination Survey (NHANES). Multivariable linear regression model was adjusted for age, sex, race (in ARIC, we used race-center), total energy intake, education, income (NHANES only), smoking status, physical activity, alcohol intake, and margarine intake (ARIC only). Estimates were meta-analyzed using fixed-effects model. In NHANES, survey-weighted linear regression was used (weighted N= 64,294,854). PDI, plant-based diet index, CI, confidence interval.
