O17 Evaluación de los niveles de vitamina D en pacientes adultos con diabetes tipo 2 y su relación con la densidad mineral ósea y la prevalencia de fracturas vertebrales

Introduction: Low levels of 25(OH)D are associated with impaired β-cell function, insulin resistance, and increased risk of type 2 diabetes mellitus (T2DM). On the other hand, most studies report an increased risk of hip fracture in T2DM, but the data are contradictory regarding vertebral fractures (VF). Objectives: Evaluate 25(OH)D levels in adult patients with T2DM and its relationship with glycemic control, severity of T2DM and cardiovascular disease (CVD) risk factors, and to evaluate the bone mineral density of the lumbar spine (LS-BMD) and of the femoral neck (FN-BMD) in conjunction with the prevalence of VF. Materials and methods: A cross-sectional study was performed and we evaluated 25(OH)D levels and prevalence of morphometric VF. 209 patients with T2DM (T2DM group) and 172 patients without T2DM were evaluated, who were included as control group (CG). The level of 25(OH)D, bone mineral density (BMD) of the lumbar spine (BMD-L) and femoral neck (BMD-FN) were determined. Spine radiographs were obtained to assess the presence of morphometric VF and abdominal aortic calcifications (AAC). Logistic regression analyzes were performed. Differences were considered statistically significant at p < 0.05.
