摘要
目的了解盐碘含量调整后,珠海市人群碘营养状况,为适时采取针对性防治措施和科学调整干预策略提供依据。方法选择2011年和2015年食用碘盐的居民户和8～10岁儿童为研究对象,采集居民户盐样和儿童尿样,检测盐碘和尿碘含量。结果2011年和2015年共检测盐样1 730份,合格碘盐食用率均高于97%。2015年盐碘中位数(23. 30 mg/kg)低于2011年(30. 49 mg/kg),差异有统计学意义(Z=-31. 224,P=0. 000); 2011年和2015年共检测900份儿童尿碘,2015年儿童尿碘中位数(133. 95μg/L)低于2011年(216. 85μg/L),差异有统计学意义(Z=-9. 351,P<0. 05);香洲区(Z=-10. 177)和金湾区(Z=-7. 204) 2015年儿童尿碘中位数均低于2011年的,斗门区(Z=-2. 826) 2015年儿童尿碘中位数高于2011年(P<0. 05)。结论新国家标准《食用盐碘含量》实行后,政策得到有效落实,珠海市居民户盐碘含量已下降,8～10岁儿童尿碘整体水平下降,珠海市人群碘营养状况总体在适宜水平,但各区碘营养并不均衡,还应该持续深入的开展碘缺乏病防治知识的健康教育和监测。
Objective To investigate the status of iodine nutrition after adjustment of salt iodine content among population in Zhuhai City,and to provide a basis for timely adopting targeted prevention measures and scientifically adjusting intervention strategies. Methods Households consumed iodized salt and children aged 8-10 years in 2011 and 2015 were selected as the research subjects. Households’ salt samples and children’s urine samples were collected,and then the iodine contents in salt and urine samples were detected. Results A total of 1,730 salt samples were tested in 2011 and 2015,and the consumption rates of qualified iodized salt were both more than 97%. The median of salt iodine in 2015 was lower than that in 2011(23. 30 mg/kg vs.30.49 mg/kg),with a statistically significant difference(Z =-31.224,P = 0.000). A total of 900 urinary iodine samples collected from the children were detected in 2011 and 2015. The median of urinary iodine in the children in 2015 was lower than that in 2011(133.95 μg/L vs. 216.85 μg/L),showing a statistically significant difference(Z =-9.351,P<0.05). The medians of urinary iodine in children in Xiangzhou District(Z =-10.177) and Jinwan District(Z =-7.204) in 2015 were both lower than those in 2011,while the median of urinary iodine in children in Doumen District(Z =-2.826) in 2015 was higher than that in 2011(P< 0.05).Conclusions The control work on salt iodization had made significant effect in Zhuhai City after the implementation of the national new standard for edible salt iodine content. Iodine content of salt among households and urinary iodine level among children aged 8-10 years in Zhuhai City were both declined. The overall iodine nutrition status among population in Zhuhai City was good,but the differences existed in different districts. It is still necessary to continuously conduct health education and monitoring on knowledge related to iodine deficiency disease prevention and treatment.
