Yet among adolescents, prevalence rates of anemia are closer for males and females in some parts of the world. The prevalence of anemia is disproportionately high in developing countries, due to poverty, inadequate diet, certain diseases, pregnancy and lactation, and poor access to health services. Young people are particularly susceptible because of their rapid growth and associated high iron requirements. Anemia is a critical health concern because it affects growth and energy levels. In pregnancy it is associated with premature births, low birth weight, and perinatal and maternal mortality.
Adolescence is an opportune time for interventions to address anemia.
In addition to growth needs, girls need to improve iron status before pregnancy. And both boys and girls are more accessible to information about anemia through schools, recreational activities, and via the mass media than they will be later in their lives. A significant percentage of adolescents in the developing world are anemic, causing considerable health consequences for this age group. 8 Body growth slows down late in adolescence, at which point the iron status of boys appears to improve. Adult men, therefore, typically have larger iron stores than women.
