摘要
目的探讨陕西省渭南市居民碘营养水平与生活饮用水碘含量的关系。方法 2017年, 在渭南市下辖的10个县(市、区), 每个县(市、区)按照东、西、南、北、中5个方位各抽取1个乡(镇、街道办事处, 以下简称乡镇), 每个乡镇抽取1所小学, 每所小学抽取8 ~ 10岁儿童42名(年龄和性别均衡), 采集儿童尿样和家中食用盐盐样, 检测尿碘、盐碘含量, 并检查儿童甲状腺肿大情况;每个乡镇抽取孕妇21名, 采集孕妇尿样和家中食用盐盐样, 检测尿碘、盐碘含量。同时, 采集乡镇居民生活饮用水水样, 检测水碘含量。采用多元线性回归进行尿碘与水碘、盐碘相关关系的分析。结果分别采集儿童、孕妇尿样2 100、1 050份, 尿碘中位数分别为254.51、172.55 μg/L。分别采集儿童、孕妇家中食用盐盐样2 100、1 050份, 盐碘中位数分别为24.00、24.44 mg/kg。共采集水样232份, 水碘中位数为26.53 μg/L。共检查儿童甲状腺2 100人, 其中甲状腺肿大65人, 甲状腺肿大率为3.10%。儿童尿碘与水碘的回归模型有统计学意义(F= 6.48, P<0.05), 多元线性回归方程为=235.52 + 1.01x, 决定系数(R^(2)) = 0.119, 即尿碘的变化中有11.9%与水碘的变化有关。结论渭南市儿童碘营养为超适宜量水平, 孕妇碘营养为适宜水平。儿童尿碘的变化中有11.9%可以由水碘的变化解释。
Objective To explore the relationship between iodine nutrition level and iodine content in drinking water in Weinan City,Shaanxi Province.Methods In 2017,in 10 counties(cities,districts)under the jurisdiction of Weinan City,one township(town,sub-district office,hereinafter referred to as the township)was selected in each county(city,district)according to the 5 directions of east,west,south,north,and middle.One primary school was selected in each township,and 42 children aged 8 to 10(age and gender balanced)in each primary school were selected,urine samples and household edible salt samples were collected to test the contents of urinary iodine and salt iodine,and children's goiter was examined.Twenty-one pregnant women were selected from each township,urine samples and household edible salt samples were collected to test the contents of urinary iodine and salt iodine.At the same time,the drinking water samples of residents in townships were collected to test water iodine content.The correlation between urinary iodine,water iodine and salt iodine was analyzed by multiple linear regression.Results Urine samples of 2100 and 1050 were collected from children and pregnant women,and the median urinary iodine was 254.51 and 172.55μg/L,respectively.Edible salt samples of 2100 and 1050 were collected from children and pregnant women,and the median salt iodine was 24.00 and 24.44 mg/kg,respectively.A total of 232 water samples were collected,and the median water iodine was 26.53μg/L.A total of 2100 children's thyroids were examined,of which 65 had goiters,and the goiter rate was 3.10%.The regression model of urinary iodine and water iodine in children was statistically significant(F=6.48,P<0.05),the multiple linear regression equation was=235.52+1.01x,coefficient of determination(R^(2))=0.119,11.9%of the change of urinary iodine was related to the change of water iodine.Conclusions Children's iodine nutrition in Weinan City is at an ultra-adequate level,while pregnant women's iodine nutrition is at an appropriate level.El
