Low vitamin D status commonly accompanies obesity, and both deficiency obesity have been associated with falls fracture risk in older adults. We aimed to determine the associations of serum 25-hydroxyvitamin (25(OH)D) concentrations physical performance bone health community-dwelling, overweight obese men women. Serum 25(OH)D were measured 84 participants body mass index ≥25 kg/m2 (mean ± SD age 62.4 7.9 years; 55% women). Physical function was determined by short battery, hand grip quadriceps strength, stair climb power tests. Body composition structure assessed dual-energy X-ray absorptiometry peripheral quantitative computed tomography, respectively. Mean 49.6 17.7 nmol/L, 50% had low (<50 nmol/L) levels. positively quadricep strength women (B = 0.15; 95% CI 0.02–0.27 kg B 1.07; 0.12–2.03 W, respectively) but not men.
