摘要
目的掌握碘缺乏病现状,为制定防治方案提供依据。方法采用触诊和B超法检查8～10岁儿童甲状腺;检测儿童和育龄妇女尿碘;测定儿童智商;入户调查居民健康知识和食用盐;在克汀病高危地区搜索新发克汀病病例。结果共调查4县14乡,儿童甲状腺肿大率触诊法为7.8%(102/1308),B超法为5.5%(69/1248);尿碘中位数儿童为189.81μg/L,育龄妇女为121.25μg/L,≥100μg/L者儿童占78.2%,育龄妇女占56.5%;儿童智商值平均为78.4;居民碘盐食用率为66.3%;居民健康知识知晓率为25.3%;未发现可疑的克汀病新发病例。结论林芝地区碘缺乏病病情显著下降,防治工作取得显著成效,但仍存在碘缺乏发生的高危因素,尚须加强防治。
Objective To evaluate the present situation of iodine deficiency disorders （IDD） in the area of Linzhi. Methods Children＇s goiters were measured by palpation and b-ultrasound. The level of urinary iodine in children and women at the reproductive age was measured. Other parameters measured in this study included the intelligence quotient（IQ）, health knowledge and the use of iodized salt. The area of endemic cretinism was also searched for new cases. Results A total of 14 towns of 4 counties were investigated. The children＇s goiter rate as determined by palpation and b-ultrasound was 7.8% （102/1308） and 5.5% （69/1248）, respectively. The median concentration of urinary iodine of children and women was 189.81 μg/L and 121.25 μg/L, respectively. The percentage of children and women with the concentration of urinary iodine over 100 μg/L was 78.2% and 56.5%, respectively. The children＇s IQ was 78.4. 66.3% of the population consumed iodized salt. 25.3% of the population had the knowledge of using iodized salt for the disease prevention. New ease of endemic cretinism was not found in the endemic area. Conclusion The incidence of IDD is decreasing rapidly in Linzhi areas, but there are still many risk factors associated with iodine deficiency.
