Use of supplements with and without iodine in women of childbearing age in the United States
Gregory CO , Serdula MK , Sullivan KM . Thyroid 2009 19 (9) 1019-20 The iodine status of women of childbearing age in the United States has declined dramatically over the last 25 years (1,2). In fact, using criteria from the World Health Organization, certain subgroups may be classified as iodine deficient (3). Given this dramatic decline in iodine status and the critical role of iodine in fetal neurologic development, in October 2006 the American Thyroid Association recommended iodine supplementation for all pregnant and lactating women in the United States and Canada (4). | We were interested in determining the percentage of women of childbearing age in the United States taking supplements and the percentage taking supplements containing iodine. We looked at data from the National Health and Nutrition Examination Survey (NHANES) for the years 2001–2006. NHANES is a stratified, multistage survey that provides a representative sample of the noninstitutionalized U.S. population (5). Information collected includes the use of any vitamins, minerals, or other dietary supplements within the previous 30 days. Product names are obtained and are compared to a database containing information including vitamin and mineral content. | The reported use of any supplement and use of a supplement containing iodine within the previous 30 days is presented in Table 1 for nonpregnant women of childbearing age (15‱44 years) and pregnant and lactating women. Less than half of nonpregnant women were taking any supplement compared to three fourths of pregnant women and two thirds of lactating women. Only one fifth of nonpregnant and pregnant women and 15% of lactating women were taking a supplement that contained iodine. Although the prevalence of supplement use was much higher among pregnant and lactating women compared to nonpregnant women, the prevalence of taking a supplement containing iodine was similarly low among all groups. This indicates that a lower percentage of supplements consumed by pregnant and lactating women contained iodine compared to supplements consumed by nonpregnant women (26% and 22%, vs. 47%, respectively). |
