龙岩地区碘缺乏病病情态势分析

Analysis of IDD status in Longyan prefecture,Fujian province

１９８９年龙岩地区碘缺乏病按当时的要求方法进行了考核，达到了基本控制的标准。１９９５年为了和国际消除ＩＤＤ标准接轨，采用容量比例概率（ＰＰＳ）抽样法进行了监测。监测结果：人群平均尿碘，１９９５年（２２７．７６μｇ／Ｌ）比１９８９年（１４７．５１μｇ／Ｌ）提高了５４．４％，差异显著（ｔ＝２．３０，Ｐ＜０．０５）；碘盐平均含碘量１９９５年（２９．５４ｍｇ／ｋｇ）比１９８９年（１７．９３ｍｇ／ｋｇ）提高６４．８％，差异非常显著（ｔ＝３．７７，Ｐ＜０．０１）。表明人群摄入碘量１９９５年比１９８９年有明显提高。但儿童甲状腺肿大率１９９５年（２１．０１％）比１９８９年（１５．３０％）提高３７．３％，差异亦非常显著（ｕ＝７．８９，Ｐ＜０．０１），和尿碘值出现“分离现象”。

 In 1989 and 1995,evaluations on IDD status in Longyan prefecture were conducted according to the criteria at that time,respectively.The results showed that IDD was basically controlled in 1989.In 1995(PPS),urinary iodine concentration was increased by 54.4%(P<005,227.76μg/L vs.147.51μg/L),iodine content in salt was increased by 64.8%(P<0.01,29,54mg/kg vs.17.93mg/kg),but total goiter rate (TGR) was also increased by 37.3%(P<0.01,21.01% vs 15.30%),as compared with that indicator in 1989.These results indecated that iodine intake in 1995 was significantly higher than that in 1989.Difference of goiter palpation diagnosis between 1989 and 1995 was the main cause of TGR increase.
