Long-term body mass trajectories and hypertension by sex among Chinese adults: a 24-year open cohort study

Abstract Evidence was limited on trajectory of body mass index (BMI) through adulthood and its association with hypertension. We aimed to evaluate their association by sex in large-scale study. Data were obtained from the China Health and Nutrition Survey (CHNS) from 1991 to 2015. Latent class traje...
