摘要
目的了解唐山市8-10岁儿童尿碘水平并分析可能的影响因素,为完善碘缺乏病防治策略提供科学依据。方法按照《河北省碘缺乏病监测实施方案（试行）》要求,2010-2013年在唐山市各县（市、区）采集100名8-10岁儿童即时尿样,测定其尿碘含量;检查其甲状腺肿大情况;监测其家中食盐的碘含量;监测其所在村的居民饮用水碘含量;随机抽取50名其所在村18-40岁育龄妇女,测定尿碘含量;询问儿童及育龄妇女口味是否偏重情况。将各县（市、区）按城市与农村分成两组,比较两组之间尿碘、水碘、盐碘等各项指标是否存在差异;分析尿碘与水碘、盐碘等各项指标之间的相关性。结果全市共检测儿童尿样1400份,各县（市、区）尿碘中位数均在100-300μg/L之间,在200-300μg/L之间的有9个县区,占64.3%;尿碘含量低于50μg/L的比例为4.1%（小于20%）,高于300μg/L的比例为30.5%。城市与农村之间尿碘水平、水碘、盐碘含量、口味偏重比例、甲肿率差异均无统计学意义（P〉0.05）。儿童尿碘水平与育龄妇女尿碘水平及口味偏重比例有相关性（r=0.89,P〈0.05;r=0.81,P〈0.05）;与水碘、盐碘含量及儿童甲肿率未呈现相关关系（P〉0.05）。结论唐山市儿童碘营养水平整体达到了国家要求,但是处于超适宜水平;尿碘水平与口味偏重比例,即与碘盐摄入量正相关。
Objective To understand the urinary iodine level state of children aged 8-10 years in Tangshan city,and to analyze the possible influencing factor,in order to provide a scientific basis for the relevant policy to prevent and control iodine deficiency disorders. Methods According to the requirements of Hebei province iodine deficiency disorders monitoring implementation project（ trial）,100 children aged 8-10 years were randomly sampled from each county in Tangshan city,to detect their urinary iodine content; rates of goiter; iodine content of salts from their home; and drinking water iodine value from their village; urinary iodine content of fertile women aged 18-40 years old were randomly selected,urine iodine value were detected; the tastes whether they be fond of more salt intake were surveyed. Compared the monitoring results between urban and rural areas as 2 groups,to see if there is difference between urinary iodine concentrations,values of water iodine,iodine contents of edible salt,etc. The correlations between urinary iodine concentrations and values of water iodine,iodine contents of edible salt,etc were analyzed. Results A total of 1400 children＇s urine samples were detected,all medians of urine iodine concentration in 14 counties（ cities,counties） were among 100-300 μg / L,there were 9 counties whose medians of urine iodine concentration were among 200-300 μg / L,accounted for 64. 3%; urine iodine concentration less than 50μg /L was 4. 1%（ less than 20%）,urine iodine concentration higher than 300 μg /L was 30. 5%. There were no significant difference in urine iodine level,water iodine contents,edible salt iodine contents,the proportion of taste over-emphasize and prevalence of goiter differences. The urine iodine level of children and fertile women is correlated to taste over-emphasize（ r = 0. 89,P〈0. 05; r = 0. 81,P〈0. 05）,is not correlated to water iodine,salt iodine values and children prevalence of goiter（ P〈0. 05）. Conclusions Children＇s iodine nutrition level meet the national request in Tangshan city,but exceed the appropriate level; there was a positive relationship between urinary iodine level,which is iodized salt intake.
