OBJECTIVES: The aim of our study was to evaluate the relationship between bone mineral density (examined by DXA - dual energy x-ray absorptiometry), vitamin D3 levels and the signs of metabolic syndrome. METHODS: We examined 55 subjects (37 women, 18 men, age median 67.8 years) with no history of osteoporosis, suffering from metabolic syndrome (defined as abdominal obesity and more than 2 of other components - arterial hypertension, dyslipidemia and diabetes mellitus or impaired glucose tolerance, according to IDF, 2006). RESULTS: Osteoporosis (T-score less than - 2.5) was found in 32.7 % (15 women and 3 men) and osteopenia (T-score between - 1.5 and - 2.5) in 29 % (13 women and 3 men) of patients. We observed a negative correlation between BMI and fat percentage (examined by DXA) and vitamin D3 levels. Low concentration of vitamin D3 was found in 90 % of patients with median 19.36 ug/l (64 % measured in winter, 36 % in summer, no relationship between vitamin D3 levels and season). We also observed a negative correlation between the low concentration of vitamin D3 and presence of diabetes mellitus as a part of metabolic syndrome. CONCLUSION: The link between osteoporosis and metabolic syndrome could influence the therapeutic approach in both disorders and vitamin D supplementation may play an important role in prevention of these severe conditions (Tab. 5, Fig. 1, Ref. 29).
