摘要
目的分析江西省孕妇碘营养状况,为孕妇科学补碘提供依据。方法2019年,采用系统抽样方法,在江西省11个设区市的100个县(市、区,简称县),每个县按东、南、西、北、中5个方位各抽取1个乡镇(街道),每个乡镇(街道)抽取20名孕妇(早、中、晚孕期均衡),进行家庭食用盐盐样和尿样的碘含量测定。分析比较各设区市孕妇盐碘、尿碘水平以及不同孕期尿碘分布。结果共采集孕妇家庭食用盐盐样10000份,盐碘中位数为24.53 mg/kg,合格碘盐食用率为97.05%(9705/10000),碘盐覆盖率为99.80%(9980/10000);各设区市孕妇家庭食用盐碘含量比较,差异无统计学意义(H=3.42,P>0.05)。共检测孕妇尿样10000份,尿碘中位数为175.58μg/L,各设区市孕妇尿碘含量比较,差异有统计学意义(H=28.80,P<0.01);不同孕期孕妇尿碘分布比较,差异无统计学意义(χ2=5.73,P>0.05)。结论江西省孕妇碘营养处于适宜状态,但各地孕妇碘营养状况分布不均,需关注重点地区孕妇的碘营养状况。
Objective To study the iodine nutritional status of pregnant women in Jiangxi Province,and to provide basis for iodine supplementation scientifically.Methods In 2019,100 counties(cities,districts,referred to as counties)of 11 cities in Jiangxi Province were selected by systematic sampling.Each county was divided into five sections according to five directions:east,west,south,north and middle.One township(street)was taken in each section,and 20 pregnant women(balanced early,middle and late pregnancy)were taken from each township(street)to detect their family salt iodine and urinary iodine levels in order to compare the levels of salt iodine and urinary iodine of different cities and the distribution of urinary iodine in different stages of pregnancy.Results A total of 10000 edible salt samples were collected from the families of pregnant women,the median of salt iodine was 24.53 mg/kg,the consumption rate of qualified iodized salt was 97.05%(9705/10000),and the iodized salt coverage rate was 99.80%(9980/10000).There was no significant difference in the iodine content of edible salt of pregnant women in different cities(H=3.42,P>0.05).A total of 10000 urine samples were collected from pregnant women,the median of urinary iodine was 175.58μg/L.There was a statistically significant difference in the urinary iodine content of pregnant women in different cities(H=28.80,P<0.01).There was no statistically significant difference in urinary iodine distribution of pregnant women in different stages of pregnancy(χ2=5.73,P>0.05).Conclusion The iodine nutritional status of pregnant women in Jiangxi Province is in a suitable state,but the distribution of iodine nutritional status of pregnant women in different regions is uneven,iodine nutritional status of pregnant women in key regions should be paid attention to.
