目的监测黟县孕妇尿碘水平,了解辖区孕妇的碘营养状况,为孕妇科学补碘提供依据。方法采用砷铈催化法对辖区2014年度100名孕妇随机尿样的尿碘进行检测,应用SAS 9.2软件进行统计分析。结果 100名孕妇尿碘中位数为170.1μg/L,达到国家推荐标准(尿碘中位数≥150μg/L),100名孕妇中检测到尿碘值<150μg/L的人数占到45.00%。在外务工和非在外务工的孕妇尿碘值<150μg/L分别为65.79%和32.26%,有统计学意义(χ~2=10.70,P<0.01)。孕妇家中烹调过程中,在菜刚下锅、烧菜中间和菜快熟时分别添加食盐,孕妇尿碘值<150μg/L分别为26.32%、57.69%和35.29%,差异有统计学意义(χ~2=4.38,P=0.03)。结论黟县孕妇存在一定程度的碘营养缺乏,应对孕妇实施科学补碘,满足孕妇碘营养需要。
Objective To monitor the level of urinary iodine in pregnant women in Pixian County, understand the nutritional status of iodine in pregnant women in the area, and provide basis for iodine supplement in pregnant women. Methods Arsenic-cerium catalytic method was used to detect urinary iodine of 100 pregnant women random urine samples in the area in 2014, and the data were analyzed by SAS 9.2 software. Results The median urinary iodine concentration was 170.1 μg / L in 100 pregnant women, reaching the national recommended standard (median urinary iodine≥150 μg / L). The number of urine pregnant women with urinary iodine value <150 μg / L accounted for 45.00% . The urinary iodine value of pregnant women with external workers and non-external workers <150μg / L were 65.79% and 32.26% respectively, with statistical significance (χ ~ 2 = 10.70, P <0.01). Pregnant women in the process of cooking, just in the pan, the middle of vegetables and fast food were added salt, pregnant women urinary iodine value <150μg / L were 26.32%, 57.69% and 35.29%, respectively, the difference was statistically significant (χ ~ 2 = 4.38, P = 0.03). Conclusion There is a certain degree of deficiency of iodine nutrition in pregnant women in Shexian County, so iodine should be supplemented scientifically to meet the iodine nutrition needs of pregnant women.
