Trajectories of mid-life to elderly adulthood BMI and incident hypertension: the China Health and Nutrition Survey.

ABSTRACT:

Objectives

This study is designed to identify different body mass index (BMI) trajectories of individuals aged 40-70 years and test the effect of distinct BMI trajectories on incident hypertension.

Design

The accelerated longitudinal design was used for this study.

Methods

The study drew data from the third to ninth China Health and Nutrition Surveys (CHNS), and 4697 participants were included between 1991 and 2015. As analysed, three distinct individual BMI trajectories were identified by the latent class growth mixed model (LCGMM). Then, BMI values and BMI slopes were worked out through calculation with LCGMM trajectory parameters and their primary derivatives, respectively. Later, Cox proportional hazard models were applied to examine BMI values and slopes, and fin
