Desnutrição perinatal e o controle hipotalâmico do comportamento alimentar e do metabolismo do músculo esquelético

Abstract

Undernutrition during the critical period of development has been associated with susceptibility to obesity and diabetes Mellitus in adulthood. One of the underlying mechanisms can be related with the relationship between the food intake and the metabolism of skeletal muscle. A communication between the hypothalamus and skeletal muscle has been recently proposed, which can explain the repercussion of perinatal undernutrition. Thus, this review aims mainly to discuss the repercussions of perinatal undernutrition on food intake and skeletal muscle metabolism by adrenergic signals. Articles published from 2000 to 2011 were searched in the Medline/Pubmed, Lilacs and Bireme databases using the following keywordsfeeding behavior, energy metabolism, protein malnutrition, developmental plasticity, skeletal muscle and autonomic nervous system. In conclusion, perinatal undernutrition can alter the hypothalamic control of food intake and skeletal muscle metabolism. Additionally, communication between the hypothalamus and skeletal muscle can promote the development of obesity and associated diseases.
