新疆乌鲁木齐地区人群碘摄人量与甲状腺疾病的相关研究

目的 了解乌鲁木齐地区人群目前碘营养状况、甲状腺疾病流行情况并探讨两者的关系.方法 对新疆乌鲁木齐地区1693名成人进行体格检查、问卷调查,并测定平均尿碘中位数、甲状腺功能、甲状腺相关抗体和进行甲状腺B超检查.结果 在调查人群中,碘缺乏人数仅占9.5％,而碘过量人数达到30.0％.平均尿碘中位数达254.9 μg/L.碘充足/超足量组TT4水平明显高于其他两组(9.02±2.63)对(7.69±2.85)、(8.45±2.13)μg/dl,均P＜0.05],碘缺乏组TSH水平显著高于其他两组(3.00±1.86)对(2.37±1.91)、(2.27±1.86) mIU/L,均P＜0.01].各组甲状腺球蛋白抗体、甲状腺过氧化物酶抗体阳性率及甲状腺功能异常、甲状腺结节患病率没有统计学差别.结论 目前新疆乌鲁木齐地区碘缺乏状态已纠正,平均尿碘中位数254.9 μg/L.不同碘摄入状态人群甲状腺疾病患病率无统计学差别.

Relationship between iodine intake and the prevalence of thyroid disease in Urumqi, Xinjiang

Objective To evaluate the relationship between iodine intake and the prevalence of thyroid diseases in Urumqi.Methods A total of 1693 subjects were investigated.Serum thyroid hormones,thyroid autoantibodies,and urinary iodine concentration were determined,and type B ultrasonography of thyroid gland was performed in all participants.Result The urinary iodine level revealed that 9.5％ of the subjects were iodine deficient and 30.0％ iodine excessive.The average median urinary iodine was 254.9 μg/L.Serum total T4 level in the idione adequate and more than adequate groups was significantly higher than the other 2 groups ( 9.02±2.63 ) vs (7.69±2.85)、(8.45 ±2.13 ) μg/dl,both P＜0.05 ],and serum TSH level in the idione deficient group was significantly higher than the other 2 groups (3.00±1.86) vs (2.37±1.91),(2.27±1.86) mIU/L,both P＜0.01 ].There was no significant statistical difference in positive rates of thyroid autoantibodies,morbidities of thyroid dysfunction and goiter among 3 groups.Conclusion The iodine deficient situation has been corrected in Urumqi.There is no difference in morbidities of thyroid diseases in population with different iodine intakes.
