Prevalencia de hipovitaminosis D en población trabajadora sanitaria

Abstract

Introduction: In recent years have appeared a large number of scientific evidence of the high prevalence of hypovitaminosis D in the general population. Objectives: To analyze the levels of vit. D in a group of health workers. Methods: Descriptive study. Were analyzed by through microparticles chemiluminescent immunoassay (CLIA), the analyte 25 OH vit. D and Parathormone (PTHi). For the bivariate analysis chi-square an Student's t test was applied. Significance was considered p <0.05. Subsequently, it was performed a logistic regression (L.R.) whose measure of association was the odds ratio (OR). It has built two models, one considering deficit vit. D levels below 30 ng / ml, and another to levels, below 20 ng / ml. Results: It has been observed a prevalence of hipoavitaminosis D, of 84.9% (80.8% - 89.1%). Variables sunbathing or UVA in the last month together with PTHi levels, are the variables that are associated with hypovitaminosis Interestingly, when constructing LR model will cut at 20 ng / ml, sun exposure is the only significant variable. Conclusions: There is a very high prevalence of hypovitaminosis D in the health worker population studied. PTH has an odd behavior according with vit. D cutoff considered.
