Efeito da intervenção multidisciplinar sobre a insatisfação da imagem corporal em adolescentes obesos / Effects of a multidisciplinary intervention on body image dissatisfaction in obese adolescents

O objetivo do presente estudo foi analisar os efeitos da intervenção multidisciplinar sobre a insatisfação da imagem corporal em adolescentes obesos. Trinta e quatro adolescentes obesos com idade entre 12 a 19 anos, IMC?95th e púberes, foram submetidos à intervenção multidisciplinar composta por acompanhamento nutricional, psicológico, clínico e sessões de exercício físico. A insatisfação com a imagem corporal foi verificada através do Body Shape Questionnaire (BSQ). As avaliações foram realizadas antes e após 12 semanas de intervenção. Os efeitos da intervenção sobre a insatisfação da imagem corporal foram verificados utilizando-se o Qui-quadrado. Todas as análises foram realizadas com auxílio do software SPSS 10.0, p<0,05. Verificou-se no início da intervenção que 80,95% dos adolescentes apresentavam insatisfação com a imagem corporal, e após as 12 semanas de intervenção houve uma redução para 60,90% dos adolescentes com algum grau de insatisfação com a imagem corporal (p=0,05). Conclui-se que a intervenção multidisciplinar é uma importante estratégia para reduzir a insatisfação com a imagem corporal de adolescentes obesos.

The aim of this study was to analyze the effects of a multidisciplinary intervention on body image dissatisfaction (BID) in obese adolescents. Thirty four obese adolescents aged between 12 to 19 years, BMI?95 percentile and pubescent, were submitted to a multidisciplinary intervention composed by nutritional, psychological and clinical counseling and exercise sessions. BDI was determined assessed through by Body Shape Questionnaire (BSQ). Evaluations were performed before and after 12 weeks of intervention. The results are presented as mean (X) +standard deviation (SD) and distribution of absolute and relative frequency. The effects of the intervention on BDI were verified using chi-square test. All the analyses were performed using the software SPSS 10.0, p<0.05. A the beginning of intervention 80.95% of the adolescents were dissatisfied with their body image, after 12 weeks this value was reduced to 60.90% (p=0.05). The multidisciplinary intervention is an important strategy to reduce the dissatisfaction with body image of obese adolescents.

Acute effects of aerobic exercise on mood and hunger feelings in male obese adolescents: a crossover study.

BACKGROUND: The aim of this study was to determine the acute effects of exercise intensity on anxiety, mood states and hunger in obese adolescents. METHODS: Subjects were eight male obese adolescents (age 15.44 ± 2.06 y; BMI 33.06 ± 4.78 kg/m2). Each subject underwent three experimental trials: (1) Control, seated for 30 min; (2) Low intensity exercise (LIE)--exercise at 10% below ventilatory threshold (VT); (3) High intensity exercise (HIE)--exercise at 10% above VT. Anxiety (STAI Trait/State), mood (POMS) and hunger (VAS) were assessed before and immediately after the experimental sessions. Comparisons between trials and times were assessed using Kruskal-Wallis and Wilcoxon tests, respectively. Associations between variables were described using a Spearman test. RESULTS: The largest increase in hunger was observed after LEI (914.22%). Both exercise sessions increased anxiety, fatigue and decreased vigor (p < 0.05). CONCLUSIONS: Acute exercise bouts are associated with negative changes in anxiety and mood, and with increases in hunger in obese adolescents.
