碘盐浓度调整后广州市8 ~ 10岁儿童甲状腺容积调查

Thyroid volume of children aged 8−10 years in Guangzhou after reduction of iodine concentration in salt

  • 摘要:
    目的 了解盐碘浓度下调后广州市8 ~ 10岁儿童甲状腺容积现况,为评价碘缺乏病防治效果提供参考和制定防治措施提供依据。
    方法 采用多阶段分层随机抽样方法,在市区、近郊和远郊分别抽取监测点小学,然后每所小学抽取8 ~ 10岁儿童开展调查。
    结果 广州市8 ~ 10岁儿童甲状腺容积中位数为3.53 ml。 甲状腺容积在各年龄组之间有差异,并随着年龄的增大而增大。 甲状腺肿大率(甲肿率)为3.92%,与盐碘浓度下调前相比,差异无统计学意义。 不同年龄儿童甲肿率有差异。
    结论 广州市8 ~ 10岁儿童甲状腺容积整体处于正常范围内,地方性甲状腺肿患病率处于较低水平,盐碘浓度下调后儿童碘营养状况仍处于良好状态。

     

    Abstract:
    Objective To understand the status of thyroid volume of children aged 8−10 years in Guangzhou after the reduction of iodine concentration in salt, and provide evidence for the evaluation of the performance of iodine deficiency disorder prevention and treatment and the development of the prevention and treatment measures.
    Methods A multi-stage stratified random sampling method was used to select the primary schools in the urban area, suburban area and outer suburbs of Guangzhou, and the children aged 8−10 years in each school selected were surveyed.
    Results The median of thyroid volume of children aged 8−10 years in Guangzhou was 3.53 ml. The thyroid volume varied in age groups and increased with age. The prevalence rate of endemic goiter was 3.92% in children aged 8−10 years in Guangzhou, the difference in the rate was not significant compared with that before the reduction of iodine concentration in salt. There were differences in the prevalence rate of endemic goiter among children in different age groups.
    Conclusion Overall, the thyroid volume of children aged 8−10 years in Guangzhou was in normal range. The prevalence rate of endemic goiter was low. The iodine nutrition of children was still in good status after the reduction of iodine concentration in salt.
