广西沿海产盐区人群甲状腺结节流行状况及相关因素分析

Analysis of prevalence and related factors of thyroid nodules in local people in coastal salt-producing area in Guangxi

目的掌握广西沿海产盐区人群甲状腺结节患病情况及其影响因素,为科学补碘提供依据。方法于2015年1月,从广西沿海产盐区选取620名20岁及以上成人进行问卷调查、甲状腺超声检查,同时检测尿碘、水碘、盐碘含量。结果人群尿碘中位数为60.12μg/L,甲肿检出率为3.55%,甲状腺结节检出率为22.90%。多因素非条件logistic回归分析结果提示,年龄较高人群易患甲状腺结节（OR=1.50,95%CI：1.16-1.95）。结论广西沿海产盐区人群碘营养状况欠佳,年龄是当地人群甲状腺结节的主要影响因素。

Objective To know the prevalence and related factors of thyroid nodules in local people in coastal salt-producing area in Guangxi and to provide the basis for scientific iodine supplement. Methods A total of 620 adults aged 20 and older were chosen from coastal salt-producing area in Guangxi and questionnaire and thyroid ultrasonography examination,determination of urine iodine,water iodine and salt iodine were conducted. Results The median urinary iodine was 60.12 μg/L,the goiter rate was 3.55% and the thyroid nodules rate was 22.90%. Multivariate logistic regression analysis showed that older people were susceptible to thyroid nodules（OR =1.50,95% CI：1.16-1.95）. Conclusion The present study shows that the iodine nutrition of local people in coastal salt-producing area in Guangxi is poor and age is the main influence factor of thyroid nodules rate.
