A total of 3 783 urine samples were tested, and the median urinary iodine was 192.44 μg/L. The median urinary iodine of pregnant women in urban, plain and mountainous areas (205.08, 193.61 and 182.75 μg/L) was significantly different ( H = 17.53, P < 0.01); the median urinary iodine of pregnant women in different pregnancy periods (early, mid and late: 194.47, 198.19 and 183.54 μg/L) was significantly different ( H = 6.18, P < 0.05). There was no significant difference in median urinary iodine of pregnant women among different ages ( H = 2.25, P > 0.05). Conclusions:The iodine nutrition of pregnant women in Baoji City is generally at an appropriate level.
