Background: Evidence shows that the prevalence of inappropriate eating behavior (CAI) among young people has increased in recent years. It seems that body dissatisfaction (IC), the practice of excessive exercise, body composition, the socioeconomic status (NE), and ethnicity may be risk factors for CAI. Objective: To associate IC, degree of psychological impairment to exercise (GCPE), adiposity (AC), nutritional status (EN), NE and ethnicity with CAI in adolescents. Methods: Participants 362 young people of both sexes aged between 10 and 19 years. We used the Eating Attitudes Test to assess the CAI. The Body Shape Exercise Questionnaire and Commitment Exercise Scale were used to measure IC and GCPE, respectively. We evaluated skinfold thickness is to classify the AC second sex. Weight and height were measured to calculate the index of mass (BMI) and classify the EN. The NE was evaluated by Brazil Economic Classification. Questionnaire was used that sought to assess ethnicity, age and sex. Results: The results showed association of CAI with IC, GCPE and NE in females (p < 0.05). Among boys, IC, AC and EN were associated with CAI (p < 0.05). Discussion: It was concluded that IC was the main predictor of risk for the CAI.
