本文对1/2万碘盐防治地甲肿后三年中病区居民尿碘水平的变化进行了监测分析.碘盐防治后其患病率与病区居民尿碘值不存在相关关系,而与尿碘均值的离散程度呈正相关.碘盐供应中的间断和掺拌浓度不稳定是增大离散程度的主要原因.提出碘盐防治地甲肿的考核监测,应将居民尿碘含量的均值与离散程度结合起来观察.
In this paper, we monitored the changes of urinary iodine levels in the ward for three years after the prevention and treatment of 1/2-iodo-salt, and there was no correlation between the prevalence of urinary iodine and the urinary iodine value And the urinary iodine mean dispersion was positively correlated.The discontinuity in the supply of iodized salt and the instability of the blending concentration were the main reasons for increasing the degree of dispersion.It is proposed that the detection and monitoring of iodine salt to control the gonial swelling should be the average urinary iodine content of residents Combined with the discrete degree of observation.
