RESUMO

Little is known about how the intensity of aerobic training influences appetite-regulating hormones in obese adolescents. Our goal was to assess the effect of low and high intensity aerobic trainings on food intake and appetite-regulating hormones in obese adolescents. Forty three obese adolescents (age: 13-18y, BMI: 34.48 ± 3.94 kg/m2) were randomized into high intensity training (HIT; n = 20) or low intensity training (LIT; n = 23) groups for 12 weeks. All participants also received the same nutritional, psychological and clinical counseling. Pre- and postintervention energy intake (EI) and circulating levels of insulin, leptin, peptide YY3-36 (PYY3-36) and ghrelin were measured. Adolescents in the HIT showed a reduction in total EI and an increase in PYY3-36 (p < .05). Aerobic exercise training performed at ventilatory threshold 1 intensity, reduced EI and augmented PYY3-36 in obese adolescents, compared with LIT. The data suggest that HIT and LIT have differential effects in the regulation of appetite signals and subsequent EI in obese adolescents.

RESUMO

OBJECTIVE: To investigate the effects of multidisciplinary treatment with and without psychological counseling on obese adolescents' self-reported quality of life. METHODS: Seventy-six obese adolescents (15.87±1.53 y) were allocated into psychological counseling group (PCG; n=36) or control group (CG; n=40) for 12 weeks. All participants received the same supervised exercise training, nutritional and clinical counseling. Participants in PCG also received psychological counseling. QOL was measured before and after 12 weeks of intervention by Generic Questionnaire for the Evaluation of Quality of Life (SF-36). RESULTS: The dropout rate was higher in GC (22.5%) when compared with PCG (0.0%) (p<0.001). After 12 weeks, participants from PCG presents lower body weight, relative fat mass and higher free fat mass (p<0.001 for all) compared to GC. QOL improved among adolescents from both groups (p<0.05), however, a better QOL was reported from those adolescents enrolled in PCG. CONCLUSION: The inclusion of a psychological counseling component in multidisciplinary treatment for adolescent obesity appears to provide benefits observed for improved QOL as compared with treatment without psychological counseling.

Resumo Objetivo: Investigar os efeitos do tratamento multidisciplinar com e sem aconselhamento psicológico voltado para a qualidade de vida de adolescentes obesos. Métodos: Foram alocados 76 adolescentes obesos (15,87 ± 1,53 ano) em um grupo de aconselhamento psicológico (GAP; n = 36) e um grupo de controle (GC; n = 40) por 12 semanas. Todos receberam o mesmo treinamento físico supervisionado e aconselhamento nutricional e clínico. Os participantes no GAP também receberam aconselhamento psicológico. A qualidade de vida foi avaliada antes e depois das 12 semanas de intervenção por meio do Questionário Genérico de Avaliação da Qualidade de Vida (SF-36). Resultados: O abandono do tratamento foi maior no GC (22,5%) em comparação com o GAP (0,0%) (p < 0,001). Após 12 semanas, os participantes do GAP apresentam menor peso corporal, massa gorda relativa e maior massa livre de gordura (p < 0,001 para todos) em comparação com o GC. A qualidade de vida melhorou entre os adolescentes de ambos os grupos (p < 0,05); contudo, uma melhor qualidade de vida foi relatada pelos adolescentes incluídos no GAP. Conclusão: A inclusão de aconselhamento psicológico no tratamento multidisciplinar dos adolescentes obesos parece proporcionar benefícios observados na melhoria da qualidade de vida, em comparação com o tratamento sem aconselhamento psicológico.
