为了解广西碘缺乏病的防治效果,于2014年9—11月,采用人口比例概率抽样法(PPS)抽取广西30个县的30所小学1 537名8~10岁儿童和610名孕妇,检查儿童甲状腺容积,检测儿童及孕妇家中食盐的碘含量和尿碘水平。结果显示,盐碘中位数为24.20 mg/kg,碘盐覆盖率为99.07%,合格碘盐食用率为92.23%。儿童甲肿率为1.43%;儿童、孕妇的尿碘中位数分别为179.60、126.10μg/L,妊娠早、中、晚期孕妇的尿碘中位数分别为151.71、126.60、119.80μg/L,孕晚期尿碘中位数低于孕早期。提示广西碘盐新标准更适合普通人群碘营养的需求,但对孕妇略显不足,应加强对孕妇等重点人群碘营养的监测并指导这类人群科学、合理补碘。
To understand the effect of prevention and treatment of iodine deficiency disorders in Guangxi, from January to November 2014, 1,573 children aged 8 to 10 and 610 pregnant women from 30 primary schools in 30 counties of Guangxi Province were sampled by probabilistic sampling (PPS) Thyroid volume in children, detection of iodine and iodine levels in children’s and pregnant women’s homes. The results showed that the median salt iodine was 24.20 mg / kg, the iodine salt coverage was 99.07%, and the qualified iodized salt consumption rate was 92.23%. The prevalence of urinary iodine was 1.43% in children and 179.60 and 126.10μg / L respectively in children and pregnant women. The median urinary iodine of pregnant women in early, middle and late pregnancy were 151.71, 126.60 and 119.80μg / L, respectively, Lower third trimester urinary iodine than early pregnancy. Suggest that the new standard of iodized salt in Guangxi is more suitable for the needs of the general population iodine nutrition, but slightly less pregnant women should strengthen the monitoring of iodine nutrition in key populations such as pregnant women and to guide such people scientific and reasonable iodine.
