MOLINA, José Fernando et al. Levels of 25-hydroxyvitamin D and their clinical correlation with several metabolic and cardiovascular variables in a population of postmenopausal women. Acta Med Colomb [online]. 2011, vol.36, n.1, pp.18-23. ISSN 0120-2448.

Introduction: osteoporosis is the most common metabolic bone disease. Vitamin D deficiency is an important cause of secondary osteopenia and osteoporosis. It predisposes to fragility fractures and increases the risk of falling, while augmenting the risk of developing cardiovascular disease and diabetes mellitus type 1 and 2. Objective: the objective of this study was to determine the levels of vitamin D in our population study and to correlate them with bone density, vertebral fractures, and other cardiovascular and laboratory variables. Methods: we conducted a cross-sectional study of a cohort (n=205) of postmenopausal Colombian women diagnosed with osteoporosis and osteopenia. We analyzed 46 variables. Descriptive statistics were used, and multiple linear regressions were analyzed in order to determine correlations. Results: it was found that the prevalence of insufficient levels of vitamin D was 55.1% (n=113), deficient levels 16.6% (n=34), and adequate levels in only 28.29% (n=58) of patients. Comparing poor and inadequate levels, we found that deficient levels of vitamin D are a risk factor for vertebral fractures, with an RR of 1.02 (IC: 0,96 a 1.06) and for high blood pressure. with an RR of 1.47 (IC: 1.36 a 1.58). Conclusions: our study shows that inadequate levels of vitamin D are common in our population. This is associated with low bone mass, vertebral fractures, and hypertension. Further studies are needed in our country to confirm our findings (Acta Med Colomb 2011; 36: 18-23).
