Association of plant-based food intake in daily diets and hypertension in older adults: a cohort study.

ABSTRACT:

Introduction

Hypertension is a major health concern among older adults, linked to high morbidity and mortality. While plant-based diets may offer health benefits, their association with hypertension in this population remains unclear. This study examines the relationship between plant-based food intake and hypertension incidence in older adults.

Methods

We analyzed data from the Chinese Longitudinal Healthy Longevity Survey, including 3,991 hypertension-free participants aged ≥65 years at baseline (2008). Follow-up was conducted in 2011/2012. Plant-based diet intake was assessed using a plant-based diet index (PDI). Cox proportional hazard models estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for hypertension risk.

Results
