Anthropometric Profile, Serum Leptin, Antioxidant Vitamins, LEPR Q223R Polymorphism and Cardiovascular Risk Factors in Adolescents.

Cardiovascular disease (CVD) risk factors, such as bad eating habits, are typical in adolescence and lead to the consumption of meals that are not always sufficient in vitamins A, E, -carotene, excess calories and elevated serum leptin levels. The purpose of this research is to study the relationship between vitamin A deficiency (VAD), -carotene deficiency (cD), vitamin E deficiency (VED) and to explore the association of leptin receptor Q223R polymorphisms with obesity and other risk factors for CVD. This observational study included 237 adolescents recruited from Adolescents Reference Center, Brazil.
