Burden of non-sexually transmitted infections on adolescent growth and development in the developing world.
A vast majority of children living in developing countries face their teen years following a childhood of malnutrition and limited access to education and health care. In this environment of disadvantages, exposure to old and reemerging infections become a significant determinant of their likelihood to overcome poverty: tuberculosis and its rapid progression during adolescence may anticipate a premature death; malaria, as well as its debilitating recurrent febrile episodes and anemia, is responsible for most of their lost time at school or work. Furthermore, the burden of anemia and malnutrition is aggravated by infestation with common intestinal worms such as with hookworms, Trichuris trichiura and Ascaris lumbricoides. These parasites compete for iron and nutrients and produce mucosal damage and inflammation causing anorexia and worsening the intake and absorption of their marginal diets. Other infections among the many neglected tropical infectious diseases, many others common to adolescents in developed countries, and some that could be controlled by access to vaccines, add scores against the physical and intellectual fitness of millions of teens in tropical developing countries.
