Cardiovascular Risk of Community-Dwelling Elderly from a City in Northeastern Brazil: Correlations with Vitamin D and Parathormone

摘要

We investigated the cardiovascular disease (CVD) risk of the elderly in a city in northeastern Brazil, and the correlation of this risk with vitamin D and PTH status. We studied 359 elderly, both genders, from Piauí-Teresina-Brazil. Variables investigated: body mass index, waist circumference, systolic and diastolic blood pressure. A subsample (n = 100) was investigated for biochemical analyses: PTH and 25(OH)-vitamin D levels;total, HDL and LDL-cholesterol;and fasting glucose. High blood pressure, abdominal obesity, sedentarism, high total cholesterol, high triacylglycerol levels, as well as low vitamin D levels, were, among the investigated variables, the most prevalent. Visceral adiposity and low vitamin D were found to be more prevalent in women than in men, whilst alcohol intake and smoking were more prevalent in men. The correlation between vitamin D, PTH and the investigated risk variables, under our study conditions, were not significant.
