In his work we aim at identifying techniques and behaviors used by poor adolescences to change their appearance. We developed an exploratory and transversal study by using structured questionnaires. The sample was composed by 287 high school students, from both periods (day and night) of a school located in a region of low socio-economic status. Results indicate a tendency to body satisfaction and to the practice of regular physical activity as the most frequent way of taking care of the body among boys. However, concerning to the girls, diets are most common technique to change their appearance. A significant difference regarding the body satisfaction and employability was found among those who study and work. We did not find any association regarding the structure of the family. The results indicate that the students in our study do not want to compromise their health in order achieve a "perfect body".162275282Adams, G., Truner, H., Bucks, R., The experience of body dissatisfaction in men (2005) Body Image, 2, pp. 271-283Anderson, C.B., Bulik, C.M., Gender differences in compensatory behaviors, weight and shape salience, and drive for thinness (2004) Eating Behaviors, 5, pp. 1-11Avalos, L., Tylka, T., Wood-Barcalow, L.N., The Body Appreciation Scale: Development and psychometric evaluation (2005) Body Image, 2, pp. 285-297Braga, P.D., Molina, M.C.B., Figueiredo, T.A.M., Representações do corpo: com a palavra urn grupo de adolescentes de classes populares (2010) Ciência & Saúde Coletiva, 15, pp. 87-95Boltanski, L., (2004) As classes sociais e o corpo, , Rio de Janeiro: GraalCatusso, R.L., Campana, A.N.N.B., Tavares, M.C.G.C.F., A Resiliência e a Imagem Corporal de Adolescentes e Adultos com Mielomeningocele (2010) HuRevista, 36, pp. 37-45Corbin, A., Courtine, J., Vigarello, G., (2008) História do corpo, , Petropolis, RJ: VozesCyrulnik, B., (2004) Os patinhos feios, , São Paulo: Martins fontesD'Andrea, F.F., (2003) Desenvolvimento da personalidade, , Rio de Janeiro: Bertrand BrasilEco, H., (2007) A história de feiura, , São Paulo: RecordEnderle, C., (1998) Psicologia da Adolescência, , Porto Alegre:Artes MédicasGrogan, S., (1999) Body Image: understanding body dissatisfaction in men, women and children, , Nova lorque: RoutledgeHuenemann, R.L., Shapiro, L.R., Hampton, M.C., Mitchell, B.W., A longitudinal study of gross body composition and body conformation and their association with food and activity in a teenage population (1996) American Journal of Clinical Nutrition, 18, pp. 325-338Jackson, L.A., Physical attractiveness: a sociocultural perspective (2004) Body Image - a handbook of theory, research e clinical practice, pp. 13-21. , Em T.
