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<0.02), waist circumference (95.2 cm vs. 101.1 cm; p<0.03), waist-to-height ratio (0.58 vs. 0.61; p<0.03) and systolic blood pressure (120 mm Hg vs. 127.6 mm Hg; p = 0.007). Conclusions High frequency of vitamin D deficiency is associated with increased BP and adiposity in overweight adolescents.
