目的：分析佛山地区尿碘含量与甲状腺结节患病率的关系。方法：选择于2010、2011年参加健康体检的3250名18~82岁佛山地区居民的尿碘检查和甲状腺B超检查资料，分析尿碘含量与甲状腺结节患病率的关系。结果：尿碘小于100μg/L时，甲状腺结节患病率为29.26%，100~300μg/L时，患病率为26.20%，大于300μg/L时，患病率为17.80%，尿碘水平与已经存在的甲状腺结节的患病率无相关性（P=0.09）。对甲状腺结节进行直径分析，显示在存在甲状腺结节患者中，随年龄增加，甲状腺结节直径呈上升趋势（P=0.001）。结论：尿碘含量与甲状腺结节患病率无明显相关，甲状腺结节患病率随年龄增加呈上升趋势。%Objective:To analyze the relationship between urinary iodine and prevalence of thyroid nodule in people of Foshan area. Method:Thyroid B-ultrasound and urinary iodine content were checked in 3250 people aged 18-82 years old,who participated annual physical checkups in 2010 and 2011. Result:The prevalence of thyroid nodule were 29.26%,26.2%,17.80%for urinary iodine<100μg/L,within 100-300μg/L and>300μg/L respectively. There is no obvious relationship between the urinary iodine which represents the iodine intake within 24 hours and prevalence of thyroid nodule(P=0.09). The prevalence of thyroid nodules shows an upward trend with the advance of age(P=0.001). Conclusion:No obvious relationship between the urinary iodine with the prevalence of thyroid nodule. The advance of age has an upward trend with the prevalence of thyroid nodules.
