This study aimed to evaluate the effects of a multidisciplinary intervention program on the factors: stage of behavior change (SBC), physical self-description (PSD), blood pressure (BP) and physical fitness in obese adolescents. The study was characterized as quasi-experimental type, with 33 adolescents who were evaluated before and after 16 weeks of intervention. The anthropometric and fitness variables, BP were assessed, and we also applied the Stage of Change instrument and PSDQ (Physical Self-Description Questionnaire), in order to measure the SBC and the PSD, respectively. The statistical analysis involved measures of central tendency and dispersion, and the comparison between the initial and final periods was performed by Student’s t-test. The comparison between the periods before and after-intervention presented significant differences (p < 0.05) for almost all variables, except for the hip circumference, waist to hip ratio and pull-ups in the adapted bar. The program promoted effective changes in the fat consumption, and habitual physical activity and PSD of habitual physical activity, body fat and appearance. The results are quite promising and evidence the needto expand programs like this, in order to lead to the behavioral change. In this way, the physical education professional has a decisive role on this process.

O Estudo foi classificado como quase experimental realizado com 33 adolescentes que foram avaliados antes e após 16 semanas de intervenção. Foram avaliadas variáveis antropométricas, de aptidão física, PA e aplicados os instrumentos SOC (Stage of Change) e PSDQ (Physical Self-Description Questionnaire), a fim de mensurar EMC e ADF, respectivamente. A análise estatística envolveu medidas de tendência central e dispersão e a comparação entre os períodos inicial e final foi realizada pelo teste t de Student. A comparação entre os momentos pré e pós-intervenção apresentou diferenças significativas (p < 0,05) para quase todas as variáveis, com exceção da circunferência do quadril, relação cintura quadril e teste de barra adaptada. Com o estudo, foi possível considerar que o programa mostrou interferir no EMC de consumo de gorduras na dieta e atividade física habitual e na ADF de atividade física habitual, gordura corporal e aparência. Os resultados são bastante promissores e apontam para a necessidade de ampliação na abrangência de programas de intervenção com enfoque na mudança do comportamento, tendo o profissional de educação física um papel decisivo nesse processo.
