Objective: To identify the diet quality and associated factors of adolescent students from public school system in accordance with the Dietary Guidelines for the Brazilian Population. Methods: The research sample was determined by simple random sampling procedures. An electronic questionnaire was administered containing questions to assess diet quality and sociodemographic characteristics: age, sex, skin color, family income, and maternal education. Diet quality was assessed using the diet quality scale (ESQUADA), with scores categorized as “very poor,” “poor,” “good,” “very good,” and “excellent” to evaluate the association with sociodemographic data using the chi-square test and correspondence analysis. A significance level of 95% was adopted. Results: A total of 733 adolescents participated in the study, 55.25% of whom were girls, with a mean age of 16 years old. The majority (79%) had a ‘good’ diet quality. ‘Very good’ and ‘poor’ diet quality were observed in 8% and 13%, respectively. A correspondence was observed between better diet quality and male adolescents who were older and had higher income. Conclusion: It was possible to assess the public school adolescents’ diet quality by describing their food intake and eating habits in accordance with the Guide. The findings are fundamental for the planning and implementation of food and nutrition public policies aimed at this population.
