Current status of iodine deficiency in Mongolia in 1998-1999

In 1992, the Mongolian government conducted a nationwide palpation study of the thyroid glands, and the study showed an overall goiter rate of 30%. As a result of this, the Mongolian Government launched its Iodine Deficiency Disorders (IDD) Elimination Programme in 1996 and its primary strategy was salt iodization. In 1998 and 1999, we carried out programme monitoring studies in 11 provinces. The results showed: among schoolchildren, a goiter rate was 22.8% (n = 6,535), median values of urinary iodine excretion ranged from 11 micrograms/l to 256 micrograms/l (n = 1,930), and usage rates of iodized salt (> 20 PPM iodine content) in their households ranged from 3% to 82%. We concluded that severe iodine deficiency in 1992 was improved from moderate to mild severity a few years later by salt iodization. However, stronger official commitments and community participation are needed to improve the programme so that iodized salt will be made more widely available.
