Sonomorphologic evaluation of goiter in an iodine deficiency area in the Ivory Coast.

Abstract

This study evaluated the extent of thyroid abnormalities in a remote iodine-deficient area of the Ivory Coast. Ultrasonography was used in detecting the presence of goiter. The overall prevalence rates of goiter were 64.7% among females and 53.3% among males. In children aged 6 to 15 years (n = 314), the prevalence of goiter was 62% regardless of sex. Thyroid volume increased steadily with age, with significantly larger goiters in women 25 years and older. Frequency of cysts and calcifications did not correlate with sex. Especially in developing countries, prophylaxis of iodine deficiency disorders must be improved in iodine-deficient areas to prevent substantial morbidity, which is more severe in women and elderly persons.
