The perception of body image of adolescents is an instrument for nutritional assessment to health conditions. Objective: To verify the body image perception of adolescents and their parents in relation to nutritional status and blood pressure levels. Methods: Population-based study, and cross-sectional model, conducted with parents and adolescents aged 10- 19 years old, in rural and urban zones in public schools. There was applied the Scale silhouettes for parents about the perception of the described body image and a question about the concern of the nutritional status of their children. There were verified the blood pressure, weight, height and waist circumference, the BMI (kg/m²) calculation of the adolescents, and the self-perceived body image. The data was expressed as average ± standard deviation and percentages. Results: The sample consisted of 914 adolescents with a mean age of 13.12 ± 2.17 years, 56.8% female and 68.9% were eutrophic. As for blood pressure levels, 17.6% were classified in pre-hypertensive, 18.8% in stage 1 hypertension and 6% in stage 2. About the self-perception, 68% considered themselves being eutrophic and 64.75% of the parents classified their children as eutrophic. There was observed a direct and significant correlation among the body mass index, waist circumference, weight, systemic and diastolic blood pressure with the self-perception of the adolescents and the body image perceptions of the parents (p<0.001). Conclusion: The nutritional status was significantly correlated with blood pressure, waist circumference and body image perceptions of the adolescents and their respective parents.
