目的了解广西沿海碘盐覆盖率较低地区碘缺乏病防治工作现况。方法采用分层抽样方法对北海市的海城区、银海区、铁山港区、合浦县以及钦州市的钦南区等5个县区进行新发克汀病病人搜索,盐碘、尿碘、甲状腺肿大率、智商水平、外环境水碘含量等指标监测。结果搜索、发现17例“痴呆”儿童,经市、县两级专家组会诊,全部排除新发地克病;检查8~10岁儿童1 437人,触诊甲状腺肿大率平均为1.32%,B超法甲状腺肿大率平均为2.6%;儿童尿碘中位数为191μg/L,孕妇和哺乳期妇女尿样365份、尿碘中位数为132.5μg/L;儿童智商平均水平为98.3,智商低于69的占7.2%,智商高于130的占2.2%;入户调查721户,居民食盐半定量检测有碘率为51.04%;饮用水和灌溉水水碘含量处于低水平范畴。结论沿海地区碘盐覆盖率处于全区的低水平,人群碘营养水平欠佳,需要进一步加大工作力度,有效打击非碘盐冲销市场的状况,普及碘缺乏病防治知识。
Objective To understand the current status of iodine deficiency disorders prevention and treatment in areas with low coverage of iodized salt in Guangxi. Methods A stratified sampling method was used to search for patients with newly diagnosed cretinism in Haicheng, Yinhai, Tieshangang, Hepu and Qinan districts of Qinzhou in Beihai. Salt iodine, urinary iodine , Goiter rate, IQ level, external environment water iodine content and other indicators of monitoring. The results of the search found that 17 cases of “dementia” children, the city and county expert group consultation, all excluding new ones; Check 43 children aged 8 to 10, palpation rate of goiter average 1.32 %, B-type goiter rate of 2.6% on average; children with a median urinary iodine 191μg / L, urine samples of pregnant women and lactating women 365, the median urinary iodine 132.5μg / L; the average IQ of children Was 98.3, IQ was lower than 69, accounting for 7.2%, IQ was higher than 130, accounting for 2.2%; household survey 721 households, semi-quantitative detection of salt iodine was 51.04%; drinking water and irrigation water iodine content at a low level category. Conclusion The coverage of iodized salt in the coastal areas is at a low level in the whole region, and the iodine nutrition level of the population is not good. Therefore, efforts should be further intensified to effectively combat the situation of non-iodized salt elimination and to popularize the knowledge on prevention and treatment of iodine deficiency disorders.
