Relationship Between Body Mass Index-BMI and Vitamin D Concentrations in Women with Postmenopausal Osteoporosis

Introduction: Osteoporosis is the most common metabolic bone disease. Vitamin D deficiency, often associated with osteoporosis and other bone tissue disorders, is spread worldwide. Among other factors, obesity seems to be a major cause of the growing hypovitaminosis D. The aim of the study was to assess the correlation between Body Mass Index (BMI) and vitamin D concentrations in postmenopausal women diagnosed with osteoporosis. Materials and Methods: Sixty-nine women with postmenopausal osteoporosis were included in the study. Dual-energy X-ray absorptiometry and vitamin D measures were performed in all patients. Three groups, BMI- dependent, were distinguished: normal weight, overweight and obesity group. Results: Vitamin D deficiency was found in all women with postmenopausal osteoporosis. There was no correlation between BMI and vitamin D level. Conclusions: Vitamin D deficiency is frequent in the population of patients diagnosed with postmenopausal osteoporosis, regardless of their BMI.
