Association of plant-based diet indices with all-cause and cause-specific mortality among Korean adults in the KNHANES.

ABSTRACT: A plant-based diet is associated with all-cause and cardiovascular disease (CVD) mortality, but the associations might differ by plant qualities. We examined the associations between the plant-based diet index (PDI) and mortality. Adults with 24-hour dietary recall from the 2007-2015 Korean National Health and Nutrition Examination Surveys (KNHANES), who were eligible for and linked to national mortality records through 2019, were included (n = 44,291). Three PDIs were calculated: overall PDI (all plant foods), healthful PDI (hPDI, healthful plant foods), and unhealthful PDI (uPDI, unhealthful plant foods), with higher scores for respective plant foods and animal foods reverse-scored. A weighted Cox proportional hazards model estimated hazard ratios (HRs) and 95% confidence intervals (CIs)
