河南省碘盐浓度调整3年后重点人群碘营养监测结果

Iodine status of vulnerable populations in Henan Province of China three years after the implementation of new iodized salt standard

2015年在河南省18个省辖市开展重点人群碘营养监测,育龄妇女(3 318名)、孕妇(36 366名)、哺乳期妇女(4 153名)、0~2岁婴幼儿(10 127名)、8~10岁儿童(4 806名)的尿碘M(P25, P75)分别为202.1(124.0,310.0)、192.4(133.6,262.4)、168.3(119.1,248.3)、214.2(156.1,272.3)和190.0 (121.8,285.6)μg/L,除育龄妇女尿碘偏高以外,其余四类人群均达到了碘适宜的水平;育龄妇女、孕妇、8~10岁儿童超出碘适宜的比例分别为26.7%、29.4%和22.5%.

Iodine nutrition surveillance of vulnerable population was conducted in 18 cities of Henan Province in 2015. The medians and quartiles of urinary iodine concentration in women of reproductive-age (n=3 318), pregnant women (n=36 366), lactating women (n=4 153), infants<2 years of age (n=1 017), and children aged 8-10 years (n=4 806) were 202.1(124.0, 310.0), 192.4(133.6, 262.4), 168.3 (119.1, 248.3), 214.2(156.1, 272.3) and 90.0 (121.8, 285.6) μg/L, respectively. Iodine status of the vulnerable populations was generally regarded as adequate in Henan Province. But the median of urinary iodine concentration of reproductive-age women were slightly above the adequate level. The proportions above iodine adequate level were 26.7% in reproductive-age women, 29.4% in pregnant women and 22.5% in children aged 8-10 years.
