摘要
目的研究食盐加碘政策调整对长沙市8~10岁儿童碘营养水平的影响,探究儿童甲状腺肿的影响因素。方法按照国家历次食盐加碘政策调整时间分析和比较长沙市相关(1995、1997、1999、2011、2018)年份儿童碘营养指标、甲状腺容积等监测数据;采用二元logistic回归分析影响儿童甲状腺肿大的因素;建立多元线性回归模型。结果随着食盐加碘政策的不断调整,居民户盐碘含量显著改变(H=3126.25,P<0.05),合格碘盐食用率先升高后降低(χ~2=117.69,P<0.05);儿童尿碘水平随盐碘标准变化而显著改变(H=411.64,P<0.05);儿童甲状腺肿大率显著下降,盐碘值为儿童甲状腺肿的保护因素(OR=0.919,95%CI=0.877~0.963)。结论食盐碘含量的不断调整对预防8~10岁儿童甲状腺肿大有重要意义,加碘盐能有效预防碘缺乏病。
Objective To study the effect of dietary salt iodization policy adjustment on the iodine nutrition level of children aged 8-10 years in Changsha City,and to explore the influencing factors of children’s goiter.Methods According to the national salt iodization policy adjustment time(years of 1995,1997,1999,2011,2018)analysis and comparison of children’s iodine nutrition index,thyroid volume and other monitoring data in Changsha City;using binary logistic regression analysis to deal with children’s goiter factors;establish a multiple linear regression model.Results With the continuous adjustment of the salt iodization policy,the salt iodine content of the households changed significantly(H=3126.25,P<0.05),and the consumption of qualified iodized salt increased first and then decreased(χ~2=117.69,P<0.05);the urine iodine level of children,the salt iodine standard changed significantly(H=411.64,P<0.05);the thyroid enlargement rate in children decreased significantly,and the salt iodine value was a protective factor for children’s goiter(OR=0.919,95%CI=0.877~0.963).Conclusion The constant adjustment of salt iodine content is important for preventing thyroid enlargement in children aged 8-10 years.Iodized salt can effectively prevent iodine deficiency disorders.
