Objective: To verify the prevalence of abdominal obesity and its associated factors in adolescents. Material and methods: Cross-sectional and analytical study carried out in a public school in Maranhao, with 152 adolescents. Data were collected using a questionnaire with socioeconomic, demographic, lifestyle, food consumption and anthropometric variables. The dependent variable was abdominal obesity, defined by waist circumference. The Poisson regression method was performed using the Stata® version 12.0 program. Results: Of the adolescents interviewed, 56.5% were female, 39.5% were aged 17 to 19 years and 72.9% consumed soda 1 to 4 times a week. According to the BMI, 5.3% were overweight. About anthropometric indicators, 11.1% and 31.3% were at risk for cardiovascular diseases according to the waist / height ratio and neck circumference, respectively. The prevalence of abdominal obesity was 14.6%. Being aged 17 to 19 years (IRR=2.44; CI=1.16-5.13), being a smoker (IRR=4.18; CI=2.33-0.00), consuming soda (IRR=0.43; CI=0.20-0.92) and energy drinks (IRR=2.49; CI = 1.00-6.19) 1 to 4 times a week were associated with abdominal obesity. Discussion: The literature shows the association of smoking and consumption of drinks rich in added sugars with abdominal obesity. Conclusion: There is a need to adopt measures to assess, identify and monitor the nutritional status of schoolchildren, to promote early nutritional interventions.
