DAMASO, Ana R. et al. Multidisciplinary treatment reduces visceral adiposity tissue, leptin, ghrelin and the prevalence of non-alcoholic fat liver disease (NAFLD) in obese adolescents. Rev Bras Med Esporte [online]. 2006, vol.12, n.5, pp. 263-267. ISSN 1517-8692. http://dx.doi.org/10.1590/S1517-86922006000500008.
The aim of this study was to assess the changes promoted by a multidisciplinary therapy in ghrelin and leptin concentrations, visceral adiposity and non-alcoholic fat liver disease-NAFLD, in obese adolescents. A total of 28 obese adolescents, 16 girls (BMI 34.58 ± 3,86 wt/ht2) and 12 boys (BMI 37.08 ± 3.17 wt/ht2), aged between 15 and 19 years old, was evaluated to leptin, ghrelin and insulin concentrations, visceral adiposity and NAFLD through ultrasonography. The results showed a significant decrease in ghrelin, leptin concentrations and visceral adiposity (p < 0.01). Moreover, a decrease in the NAFLD prevalence was observed. It is an important result, since this disease can progress to cirrhosis, not only in children but also in obese adolescents. This kind of treatment can be efficient to improve metabolic and hormonal profile, as well as, to control obesity and related co-morbidities in obese adolescents.
