Pain and Patient-Reported Physical Function Did Not Differ Among Body Composition Profiles in Patients With Hip Osteoarthritis

Abstract

Objective: To explore whether higher body fat and lower lean mass are associated with greater pain and worse patient-reported physical function in individuals with hip osteoarthritis (OA). A secondary aim was to examine whether pain and patient-reported physical function differ according to four body composition profiles: high body fat, low lean mass, both, or neither. Methods: This cross-sectional study analyzed baseline data from two randomized controlled trials involving 160 individuals with symptomatic hip OA (mean ± SD age 61.4 ± 6.2 years; 65% were female). Body fat mass percentage and appendicular lean mass (ALM) were assessed using dual-energy x-ray absorptiometry. Participants were ..
