Insufficient serum levels of 25-hydroxyvitamin d are associated with dyslipidemia in the elderly

Resumen

Objective: To identify possible associations between serum levels of 25-hydroxyvitamin D and dyslipidemia in the elderly. Method: A cross-sectional study. For sample consisted of 80 elderly people monitored at a Geriatric Outpatient Clinic of the University Hospital in Alagoas, Brazil. In this study sociodemographic variables, lifestyle, health conditions, anthropometrics, body composition and biochemical tests were collected (serum lipid profile, 25-hydroxyvitamin D, us-RCP, PTH and calcium). Results: It was observed that the concentrations of 25-hydroxyvitamin D correlated negatively with the serum concentrations of total cholesterol and LDL-c. There was no association between HDL-c, triglyceride concentrations and the variables studied (p>0.050). 25-hydroxyvitamin D was associated with the diagnosis of dyslipidemia (p=0,032). Discussion: Vitamin D was shown to be a protective factor for the development of dyslipidemia in the elderly studied and the insufficiency in serum level of vitamin D seemed to exert an influence on lipid metabolism, making the elderly even more vulnerable cardiovascular diseases.
