Abstract:

Abstract Iodine deficiency is currently the most preventable cause of brain damage and mental retardation in both the fetus and neonate and of psychomotor impairment in young children . According to the WHO and UNICEF , iodine deficiency affects some 2000 million people worldwide , representing onethird of the world population . Limited consumption during pregnancy can also lead to lasting problems with maternal thyroid function after pregnancy . The easiest and cheapest measure with the best results in preventing iodine deficiency is iodine prophylaxis using iodized salt . To achieve this , an appropriate health policy is required that keeps the general population and , in particular , women of fertile age informed . It is here that midwives , in their role as health advocates , acquire particular importance , as they are the health professionals most suited to impart health education in pregnancy .
