Predictive efficacy of waist-related indices for sarcopenic obesity incidence in Chinese older adults: a nationwide cohort study.

ABSTRACT: This study aimed to evaluate the predictive capacity of the Body Roundness Index (BRI), Abdominal Body Shape Index (ABSI), Waist-to-Weight Index (WWI), and Waist-to-Height Ratio (WHtR) for sarcopenic obesity (SO) incidence among older adults in China using data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). The cohort included 3,919 participants aged 65 and older, with a mean follow-up of 2.79 years. Sarcopenic obesity was defined by low muscle mass and high body fat. Multivariate Cox proportional hazards regression models and Generalized Additive Models (GAMs) based on the Poisson distribution were used to assess the associations and predictive performance of these indices. After adjustment, BRI (HR: 1.037, 95% CI: 1.014, 1.060), ABSI (HR: 13.247, 95% CI: 1.677, 104.660),
