RESUMO

La prevalencia entre los adolescentes, de trastornos de la conducta alimentaria como anorexia nerviosa (AN), bulimia nerviosa (BN) y otro (obesidad, alimentación compulsiva, o no especificados), viene creciendo día a día de modo sostenido y a gran velocidad; y siendo la alimentación una necesidad básica, importante y vital para el crecimiento y desarrollo, debe entenderse que este acto ejerce una conducta poderosa influencia en la estructura y funcionamiento del organismo por lo tanto una conducta alimentaria adecuada hace posible que esto se desarrolle de manera adecuada y óptima. Cada sociedad tiene formas habituales de alimentarse según sus costumbres y características socioculturales y religiosas; cuando un individuo se aparta de los límites racionales presentando características anormales tanto en la calidad como en la cantidad o distribución de las comidas a esto se le llama ôTrastornos en la Conducta Alimentariaõ. El tratamiento de los trastornos en la conducta alimentaria representa todo un desafío de Salud Pública por su alta incidencia, gravedad y evolución clínica prolongada con propensión a la cronicidad y por el grupo etáreo afectado, por lo tanto, es indispensable buscar las herramientas que permitan una detección temprana y una intervención especializada con un equipo multidisciplinario que incluya médico, psicólogo, nutricionista, psiquiatría, de modo que el pronóstico de recuperación sea el mejor posible.

RESUMO

AIM: The aim of this study was to evaluate the role of orexigenic and anorexigenic factors in an interdisciplinary weight loss therapy for obese adolescents with symptoms of eating disorders. METHODS: Thirty-seven post-pubertal, obese adolescents (14 to 19 years old) with symptoms of eating disorders were submitted to long-term interdisciplinary therapy (1 year). Bulimic and binge eating symptoms were measured using the Bulimic Investigatory Test, Edinburgh, and the Binge Eating Scale respectively. Neuropeptide Y, melanin-concentrating hormone, total ghrelin, alpha-melanocyte stimulating hormone and leptin were measured using radioimmunoassay. RESULTS: After long-term interdisciplinary therapy, the adolescents showed significantly improved body composition, visceral and subcutaneous fat and reduced symptoms of bulimia and binge eating. Intriguingly, orexigenic peptides were up-regulated after short-term therapy and down-regulated at the end of therapy, whereas the anorexigenic pathway was improved with therapy. Furthermore, after long-term therapy, a negative correlation was observed between leptin concentration and melanin-concentrating hormone. DISCUSSION: We suggest that long-term therapy promotes an intrinsic association between weight loss, improvement of eating disorder symptoms and a decrease in orexigenic factors. Together, these results represent a more effective course by which patients can normalise behaviours related to eating disorders as well the actions of hormones involved in energy balance, and thus advance obesity control. CONCLUSION: Long-term interdisciplinary therapy was effective to improve anorexigenic and orexigenic factors that influence energy balance and avoid the development of eating disorders in obese adolescents. However, the associations between eating disorders and neuroendocrine factors need to be confirmed in future studies.
