Description
Objectives
To assess whether body mass index (BMI) and body fat (BF) differ between rheumatoid arthritis (RA) patients, patients with non-inflammatory arthritis (osteoarthritis, OA) and healthy individuals, and whether disease specific measures of adiposity are required to accurately reflect BF in these groups.
Methods
641 individuals were assessed for BMI (kg/m2) and BF (bioelectrical impedance). Of them, 299 (174 RA, 43 OA and 82 healthy controls (HC)) formed the observation group and 342 (all RA) the validation group. RA disease characteristics were collected.
Results
ANOVA revealed significant differences between disease groups for BMI (p<0.05) and BF (p<0.001). ANCOVA showed that age accounted for the differences in BMI (F1,294 = 5.10, p<0.05); age (F1,293 = 22.43, p<0.001), sex (F1,293 = 380.90, p<0.001) and disease (F2, 293 = 18.7, p<0.001) accounted for the differences in BF. For a …
