Abstract Title:
Correlation between vitamin D and blood pressure in adolescents.
Abstract:
Introduction Low serum levels of vitamin D have been associated with hypertension worldwide. Hypovitaminosis D has been observed even in countries with high incidence of sunlight all year round. Several studies demonstrated a high prevalence of deficiency/insufficiency of vitamin D in adolescents. Objective To investigate the association between the nutritional status of vitamin D with anthropometric measures and blood pressure in overweight adolescents. Methods This a descriptive and cross-sectional study with overweight adolescents of both sexes aged 12-19 years. The anthropometric data, biochemical profile, blood pressure and serum vitamin D dosage were analyzed. The chi-squared test for verification of association and Student's t-test to compare medians between variables were used. Results There were high frequencies of hypovitaminosis D (34%) and hypertension (43.3%) in overweight adolescents. We observed an inverse correlation between serum vitamin D levels and BP (r = -0.28, p = 0.005). Patients with desirable serum vitamin D had lower body mass index values (31.3 kg/m2 vs. 33.9 kg/m2; p
