摘要
目的聚类分析重庆市2005年碘缺乏病监测结果，为分类指导提供参考依据。方法将碘缺乏病监测结果分为碘盐频率（碘盐覆盖率、碘盐合格率及合格碘盐食用率）、食盐含碘量（盐碘中位数）、碘营养水平（尿碘中位数）、健康教育水平（学生问卷平均分、学生及格率、家庭主妇问卷平均分及家庭主妇及格率）、儿童甲状腺肿大（甲肿）率（触诊法及B超法甲肿率）和智商6类12个指标，运用SAS9．0软件，采用系统聚类分析方法进行聚类分析。结果28个区（县）分为5组，其特点为第1组3个区（县），碘盐覆盖率（69．00％）和合格碘盐食用率（65．00％）低，甲肿率（12．59％）高；第2组2个区（县），尿碘中位数（376．5μg／L）高；第3组3个区（县），儿童智商（97．71）低；第4组12个区（县），各项指标优于前3组；第5组8个区（县），各项指标优于前4组。结论重庆市碘缺乏病防治与病情不平衡，各区域差距较大，应针对不同情况加强防治。
Objective To perform cluster analysis of the data from Chongqing City iodine deficiency disorders（IDD） surveillance in 2005 in order to adjust measures on different condition of IDD. Methods Systematic cluster analysis on the data of frequency iodized salt （iodine salt coverage rate, qualified iodine salt rate and using qualified iodine salt rate）, median of iodized salt and urine iodine, health education（average scores of questionnaire on both students and housewives, the rates of qualified scores of both students and housewives）, goiter rate determined by palpation and B-ultrasonography, intelligence quotient from Chongqing City IDD surveillance in 2005. Results 28 districts （or counties） were divided into 5 clusters. The iodine salt coverage rate was 69.00%, the rate of using qualified iodine salt was 65.00%, goiter rate was 12.59% in the first cluster which had 3 districts; the median of urine iodine was 376.5 μg/L in the second cluster which included 2 districts; the intelligence quotient was 97.71 in the third cluster which included 3 districts; the fourth cluster which included 12 districts was better than the former 3 clusters; the fifth cluster including 8 districts was better than the former 4 clusters. Conclusions The situation of IDD control in Chongqing is unbalanced with increasing gaps, different measures should be taken to prevent and control the disease.
