Objective: To estimate prevalence and analyze factors associated with body image dissatisfaction among Brazilian adolescent school students. Methods: Cross-sectional study with data from the 2019 National School Health Survey (PeNSE). Prevalence of self-reported body image dissatisfaction and respective 95% confidence intervals (95%CI) and its association with individual characteristics were estimated via odds ratios (OR) and 95% CI using logistic regression. Results: Of the 159,245 students, 30.2% (95%CI 29.2;31.1) reported body image dissatisfaction, which was associated with all factors analyzed. Likelihood of dissatisfaction was greater among females (OR = 3.86; 95%CI 3.45;4.32), having internet at home (OR = 8.68; 95%CI 6.83;11.03), thinking that no one cares about them (OR = 3.02; 95%CI 2.60;3.50), that life is not worth it (OR = 3.27; 95%CI 2.88;3.72) and feeling irritated (OR = 2.87; 95%CI 2.53;3.26). Conclusion: Body image dissatisfaction is associated with various factors and requires an intersectoral approach.
