Abstract
doi:10.1016/j.ijgo.2008.09.020 The mean UIC in the control group was 137.2±5.9 μg/L (median 112 μg/L, range 62–465), but it was significantly lower in the pregnant women (Pb0.01). MeanUIC in thewomenwhowere in the first, second, and third trimesters of pregnancy were 93.6±6.6 μg/L (median 85 μg/L, range 28–223), 90.11±6.4 μg/L (median 82 μg/L, range 25–165), and 89.8 ±3.6 μg/L (median 88 μg/L, range 39–113), respectively (Fig. 1). Notably, severe iodinedeficiency (UIC less than 50 μg/L)was found in 12 pregnant womenwhowere in thefirst trimester, 2 in thesecond, and2 in the third. These results demonstrate that even in an urban areawhere iodine intake is expected to be adequate, pregnant women may be at risk of IDD. They also indicate the need to monitor iodine intake during pregnancy in areas with recently established salt iodization programs, and raise the question of whether iodine supplementation in pregnancy should be generalized or tailored on an individual basis.
