目的了解易县8～10岁儿童碘缺乏性甲状腺肿患病情况,为碘缺乏病防治工作提供科学依据。方法按东西南北4个方位各随机抽取易县的2个乡镇,中部随机抽取1个乡镇,每个乡镇随机抽取2所小学,每所小学至少抽取40名8～10岁儿童进行甲状腺肿调查,按分度、分型、不同性别、不同年龄、不同区域分别进行统计。结果易县8～10岁儿童甲状腺肿大率为3.87%。1度甲状腺肿大率大于2度,弥漫型大于结节型和混合型。不同性别、不同年龄、不同区域甲状腺肿大率差异均无统计学意义(P值均>0.05)。结论易县8～10岁儿童甲状腺肿大率在国家碘缺乏病消除标准要求的5%以内。应继续加强学龄儿童碘缺乏病的监测工作。
Objective To understand the prevalence of iodine deficiency goiter in children aged 8 ~ 10 in Yixian County, and to provide a scientific basis for the prevention and treatment of iodine deficiency disorders. Methods Two towns in Yi County were randomly selected from four directions in east, west, south and east. One township was randomly selected in the central part of China. Two primary schools were randomly selected from each township. At least 40 children aged 8-10 years were selected for primary goiter survey. By indexing, typing, different genders, different ages, different regions were statistics. Results Yi County 8 to 10-year-old children with goiter rate was 3.87%. 1 degree goiter rate greater than 2 degrees, diffuse more than nodular and mixed type. There was no significant difference in the goiter rate between different genders, different ages and regions (P> 0.05). Conclusions The goiter rate among children aged 8 ~ 10 in Yixian County is within 5% of the national standard for eliminating iodine deficiency disorders. Should continue to strengthen the monitoring of iodine deficiency disorders in school-age children.
