Objective: this study aimed to investigate the association between serum 25-hydroxyvitamin D (25 [OH] D) and cardiometabolic risk factors in Brazilian adolescents. Methods: a cross-sectional study with 220 school adolescents aged 15 to 19 years was performed in the city of João Pessoa-PB, Brazil. The variables studied were: 25 hydroxyvitamin D (25 OH), dietary intake of vitamin D, anthropometric data (body mass index (BMI), waist circumference (WC) and waist / height ratio (RCA) and biochemistry, total cholesterol (TC), Low Density Lipoprotein (LDL), High Density Lipoproteins (HDL), triglyceride (TG), C-reactive protein (CRP), alpha acid glycoprotein (AGPA), malondialdehyde (MDA) and total antioxidant capacity (CAT), blood pressure, parathyroid hormone (PTH) and serum calcium. Enough and insufficient /deficient adolescents were compared by qui-square test and analysis of multiple lineal regression was accomplished to identify the factors cardiometabólicos associated to the seric concentration of 25 (OH) D (p < 0,05). Results: a total of 57.3% had vitamin D insufficiency/deficiency, which was more prevalent in females (79.35%). The chi-square test revealed an evident relationship between the three indicators involved in overweight assessed in this study BMI (p = 0.01), WC (p = 0.04) and AGR (p = 0.02). There was an association between the independent variable (vitamin D) and calcium and triglyceride levels. Conclusion: a high proportion of adolescents presenting insufficiency/vitamin D deficiency was ssociated with cardiometabolic risk factors.
