摘　　要：目的了解碘盐食用率不同地区的8-10岁儿童碘营养水平,为采取防制策略和措施提供依据。方法分别选择碘盐食用率在90%以下和以上的乡村作为实验组和对照组,对其8-10岁学生(283名)及其家庭(83户)的甲状腺肿大、尿碘、血色素、碘盐食用情况、饮用水碘含量及饮食习惯进行分析评价。结果两组学生甲状腺肿大率和贫血率均在5%和2%以下,无统计学意义(P>0.05)。尿碘中位数分别为133.1μg/L和192.7μg/L,有统计学意义(χ2=42.4,P<0.05)。碘盐食用率分别为52.4%和95.0%,有统计学意义(u=3.43,P<0.05)。饮用水碘中位数分别为32.1μg/L和63.2μg/L,有统计学意义(χ2=28.1,P<0.05)。结论碘盐食用率不同地区居民的碘营养水平适宜,碘盐、饮用水碘含量和饮食习惯可能是影响儿童碘营养水平的共同因素。Objective To grasp the effects on the iodine nutrition level of the residents living in the rural areas having different rates of iodized salt consumption and control strategies and measures taken to provide a basis.Methods The people who took iodized salt consumption below and above 90% served as the experimental group and control group.There were 283 students aged 8-10 year-olds and their families（83） with goiter,urinary iodine,hemoglobin,iodized salt consumption,iodine content of drinking water and eating habits were analyzed and evaluated. Results The goiter and anemia rates in two groups of students were 5% and 2% or less, no significant difference （P 〉0.05）. The median of urinary iodine were 133. 1μg/L and 192.7μg / L, respectively （X^2 =42.4; P〈0.05）. The consumption rates of iodized salt were respectively 52.4% and 95.0% （ u = 3.43 ;P 〈 0.05）. The median of iodine content in drinking water were respectively 32.1 μg / L and 63.2μg/ L （ X^2 = 28.1 ; P 〈 0. 05 ）. The eating habits of residents in the two groups were similar. Conclusion There is appropriate iodine nutrition level of residents in the areas having different salt consumption rate. And iodized salt, iodine content of drinking water and the eating habits way be the common factors for the iodine nutrition level of the residents.
