目的了解孕妇和哺乳期妇女的碘营养水平,为孕妇、哺乳期妇女科学补碘提供依据。方法 2012年在太原市娄烦县随机抽取184名孕妇、181名哺乳期妇女进行尿碘测定,并与235名育龄期妇女进行比较。结果检测184名孕妇,尿碘中位数为148μg/L,属于碘营养不足与碘营养适宜的临界水平;检测181名哺乳期妇女,尿碘中位数为154μg/L,属于碘营养适宜;检测235名育龄妇女,尿碘中位数为149μg/L,属于碘营养适宜。碘营养不足者所占比例,孕妇、哺乳期妇女和育龄妇女分别为51.09%、45.86%、28.94%;碘营养充足者所占比例,孕妇、哺乳期妇女及育龄期妇女分别为47.83%、50.83%、53.19%,前两者与育龄妇女比较差异均有统计学意义(P<0.01)。结论娄烦县孕妇碘营养略感不足,哺乳期妇女碘营养适宜。
Objective To understand the level of iodine nutrition in pregnant women and lactating women and to provide basis for scientific iodine supplementation in pregnant women and lactating women. Methods In 1997, 184 pregnant women and 181 lactating women were randomly selected for urinary iodine determination in Loufan County, Taiyuan City, and compared with 235 women of child-bearing age. Results The median of urinary iodine was 148 μg / L in 184 pregnant women, which was the suitable critical level for iodine nutrition. 181 pregnant women were tested for the median urinary iodine 154 μg / L, which was suitable for iodine nutrition. Detection of 235 women of childbearing age, urinary iodine median 149μg / L, suitable iodine nutrition. The proportion of iodine undernourishment, pregnant women, lactating women and childbearing women were 51.09%, 45.86%, 28.94% respectively. The proportion of iodine nutrition adequately, pregnant women, lactating women and women of childbearing age were 47.83%, 50.83 %, 53.19% respectively. There was significant difference between the former two and the women of childbearing age (P <0.01). Conclusion The iodine nutrition of pregnant women in Loufan County is a little less than that of lactating women.
