OBJECTIVE: To evaluate dietary fiber intake among adolescents and to analyze factors associated with the risk of insufficient consumption of this nutrient. METHODS: Cross-sectional study of 722 adolescents from the town of São Leopoldo, RS, Brazil. Sampling was by clusters, with a systematic randomization of 40 census sectors and residences, including all individuals aged 10 to 19 years. The adolescents' weight and height were measured and sociodemographic data on their families recorded. A 24-hour dietary recall and a frequency survey were used to assess dietary intakes. The quantity of dietary fiber in diets was calculated using Nutwin nutrition support software (Programa de Apoio à Nutrição), developed by the IT Department at Universidade Federal de São Paulo (UNIFESP). Statistical analysis was by means of logistic regression, employing a hierarchical model. RESULTS: The prevalence of insufficient dietary fiber intake was 69% among girls and 49.7% for boys (p < 0.001). The determinant factors of this condition among boys were non-habitual consumption of beans (OR 2.65; 95%CI 1.05-6.68) and excessive fat intake (OR 2.67; 95%CI 11.23-5.83). For girls factors were increased age (OR 5.33; 95%CI 2.33-12.2), non-habitual consumption of beans (OR 3.01; 95%CI 1.44-6.53), excessive fat intake (OR 1.85; 95%CI 1.01-3.37), dieting for weight loss (OR 2.50; 95%CI 1.10-5.70) and presence of overweight (OR 2.06; 95%CI 1.04-4.07). CONCLUSIONS: These results admit of the conclusion that excessive fat consumption and non-habitual consumption of beans are strongly linked with the risk of insufficient dietary fiber intake in both sexes and that females exhibit a greater number of risk factors for this outcome.
