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

Objectives. This study evaluated the extent of thyroid abnormalities in a r emote iodine-deficient area of the Ivory Coast. Methods. Ultrasonography was used in detecting the presence of goiter. Results. The overall prevalence rates of goiter were 64.7% among females an d 53.3% among males. In children aged 6 to 15 years (n = 314), the prevalen ce of goiter was 62% regardless of sex. Thyroid volume increased steadily w ith age, with significantly larger goiters in women 25 years and older. Fre quency of cysts and calcifications did not correlate with sex. Conclusions. Especially in developing countries, prophylaxis of iodine defi ciency disorders must be improved in iodine-deficient areas to prevent subs tantial morbidity, which is more severe in women and elderly persons.
