The associations between bone mineral density with body composition parameters in postmenopausal women

Body composition plays an essential role in bone health among postmenopausal women thus we decided to compare body composition in normal bone mass density, osteopenia and osteoporosis women. In this cross-sectional study, 142 normal, 109 osteoporotic, and 194 osteopenic postmenopausal women were selected. Socio-demographic and anthropometric characteristics were investigated. IPAQ-SF questionnaire was applied for evaluating physical activity. Body composition data were obtained using the bioimpedance analysis (BIA) method. A logistic regression model adjusted for confounders was used to estimate the risk of osteopenia and osteoporosis. The odds of osteopenia decreased by increasing Percent Body Fat, PBF (aOR: 0,922; 95% CI 0,867-0,980), Mass of Body Fat, MBF (aOR: 0,909; 95% CI: 0,872 to 0,947), Soft Lean Mass, SLM (aOR: 0,921; 95% CI 0,880-0,964), Lean Body Mass, LBM (aOR: 0,910; 95% CI 0,871-0,951), Visceral Total Body Water, TBW (aOR: 0,878; 95% CI 0,828-0,933), mineral mass (aOR: 0,356; 95% CI 0,231-0,548), body weight (aOR: 0,955; 95% CI 0,934-0,976), and Body Mass Index, BMI (aOR: 0,896; 95% CI 0,848-0,947). The odds of osteoporosis decreased by increasing PBF (aOR: 0,838; 95% CI 0,773-0,909), MBF (aOR: 0,840; 95% CI 0,792-0,891), SLM (aOR: 0,889; 95% CI 0,839-0,941), LBM (aOR: 0,910; 95% CI 0,871-0,951), Visceral Fat Mass, VFM (aOR: 0,465; 95% CI 0,351-0,615), mineral mass (aOR: 0,163; 95% CI 0,086-0,307), body weight (aOR: 0,907; 95% CI 0,876-0,938), and BMI (aOR: 0,797; 95% CI 0,733-0,867). Increased body composition parameters reduced the risk of low bone mass density.
