Associations of 4-Year Trajectories in Anthropometric and Dual-Energy X-Ray Absorptiometry-Measured Obesity Indicators with All-Cause and Cardiovascular Mortality in Older Chinese Adults.

ABSTRACT:

Introduction

Given the scarce evidence on mortality risks associated with obesity trajectories beyond body mass index (BMI), this study examined the independent associations of changes in anthropometric and dual-energy X-ray absorptiometry (DXA)-measured indicators of general and abdominal obesity with all-cause and cardiovascular mortality in older Chinese adults.

Methods

A total of 1,495 male and 1,506 female participants, with a mean age of 71.75 years and BMI at 23.75 kg/m2 at baseline in 2001-2003, were followed up on mortality till mid-2020. BMI, waist-to-hip ratio (WHR), and DXA-measured indicators including whole body fat mass (WBFM) and android-to-gynoid ratio (AGR) were assessed at baseline and year 4. Sex-specific multivariable Cox proportional hazards regression
