The weight-adjusted waist index predicts sarcopenia in community-dwelling older adults in a nationwide multicenter prospective study.

ABSTRACT: The weight-adjusted waist index (WWI) is recognized as an indicator of age-related changes in body composition. This study aimed to investigate the impact of WWI on the development of sarcopenia in community-dwelling older adults. A total of 1,724 individuals aged 70-84 years without sarcopenia at baseline (defined by AWGS 2019 criteria) from the Korean Frailty and Aging Cohort Study were followed for two years. WWI was calculated as waist circumference (cm) divided by the square root of body weight (kg). Muscle mass was assessed using appendicular skeletal muscle mass adjusted for body mass index (ASM/BMI), and muscle strength was measured by handgrip strength (HGS). WWI was negatively associated with ASM/BMI (r = -0.354, P < 0.001) and HGS (r = -0.075, P = 0.002), as determined by Spearm
