佛山地区人群尿碘含量与甲状腺结节患病率的关系研究

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100—L时，甲状腺结节患病率为29．26％，100—300№几时，患病率为26．20％，大于300州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=O．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=O．001o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。

Relationship between Urinary Iodine and Prevalence of Thyroid Nodule in People of Foshan Area

Abstract ] 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 annum 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--300μ/L and 〉300 μg/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.
