Abstract

Background: Hypothyroidism is one of the most common endocrine diseases and both mild and severe forms of this disease can affect multiple body organs.Hypothyroidism is a treatable disease and we can prevent the progression of its complications. This study was done to evaluate the relation between the prevalence of neonatal hypothyroidism and the distribution of iron deficiency in Isfahan province, Iran, in order to identify risk areas in Isfahan province, Iran to prevent neonatal hypothyroidism.Methods: In this descriptive study, the recorded data of the prevalence of hypothyroidism in newborns in Isfahan province, Iran during the years 2007-2009 were obtained from the Isfahan Province Health Center and the spatial distribution map of disease was plotted based on the data. The spatial distribution map of the iron in Isfahan province was drawn and the areas with iron deficiency were determined. Then the relationship between iron deficiency and hypothyroidism maps was investigated.Findings: The highest prevalence of hypothyroidism in neonates in Isfahan province was seen in Isfahan city with 0.954, and Semirom with 0.186 neonate in every 10000 neonate. By comparing the spatial distribution maps of hypothyroidism and iron distribution a relation obtained between these maps.Conclusion: The results reflect the impact of iron deficiency on the prevalence of hypothyroidism in neonates in Isfahan and Semirom. Women in childbearing age, pregnant women and infants are more susceptible to iron deficiency anemia, and this will explain hypothyroidism in infants.
