Abstract
BackgroundMultidisciplinary intervention is an alternative for the treatment of children and adolescent obese. However, the influence of age and menarcheal status in the pattern of metabolic response of obese girls has not been investigated. The following study examined the effects of a 12-week multidisciplinary intervention on metabolic health in overweight girls and the contribution of age and menarcheal status on the resulting changes.MethodsEighty-eight overweight girls (10 - 16 years) were considered initially for this study and randomly assigned (intervention group: n = 58; control group: n = 30). Forty-six girls completed the intervention program and 16 girls completed the follow-up for the control group. The 12-week intervention included aerobic exercises (three times per week) and nutritional intervention. Anthropometrical measures (body mass, body mass index and waist circumference), menarcheal status and metabolic profiles including glucose, insulin, triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were assessed in the beginning and after of intervention. Additionally, were calculated homeostatic model assessment-insulin resistance (HOMA-IR) and quantitative insulin sensitivity check index (QUICKI).ResultsAfter 12-week, girls decreased significantly the body mass (76.6 ± 14.7 to 75.7 ± 14.6 kg) body mass index (30.1 ± 4.0 to 29.4 ± 4.0 kg/m2) and waist circumference (98.9 ± 10.9 to 96.5 ± 11.4 cm). There were differences in HDL-C (43.1 ± 8.2 to 50.3 ± 9.4 mg/dl), TG (120.9 ± 64.3 to 93.3 ± 47.9 mg/dl) and insulin (16.9 ± 7.6 to 15.6 ± 9.8 mg/dl). Relative contribution of age was significant only for within-subject variability in waist circumference.ConclusionsThe multidisciplinary based on aerobic training intervention used in this study produced substantial benefits on metabolic health indicators in overweight girls. The changes observed were not related to inter-individual variability in age and maturity status.

Multidisciplinary intervention is an alternative for the treatment of children and adolescent obese
The purpose of this study was to determine the effects of a 12-week multidisciplinary intervention, based on aerobic training, on metabolic markers of overweight girls, and verify whether such changes induced by training are affected by age and menarcheal status
There were no differences in height, body mass and body mass index (BMI) during the 12-week training
Summary
Multidisciplinary intervention is an alternative for the treatment of children and adolescent obese. Overweight in childhood and adolescence is associated with increased risk of adult obesity and metabolic dysfunction as dyslipidemia, hypertension and insulin resistance. These conditions are involved in the atherosclerotic process and contribute to the development of cardiovascular diseases (CVD) [1,2]. The interpretation of the effects of a multidisciplinary treatment programs in obese adolescent girls on body mass should consider the possible interindividual variability associated to biological maturation. There is little information about the effects of multidisciplinary treatment programs, involving physical activity and nutritional intervention in obese adolescent girls, on body size, body composition and metabolic markers [4,9,10], and its association with age and menarcheal status
