目的 研究不同碘摄入量对≥ 14周岁人群甲状腺癌发生的影响。方法 选择盘山、彰武和黄骅 3个农村社区分别为低碘、适碘和高碘地区。入户调查 3个地区≥ 14周岁人群共 2 2 976人甲状腺癌发生情况 ,并采集当地部分居民空腹尿、饮用水和食用盐样品进行检测。结果 盘山、彰武和黄骅地区成人尿碘中位数分别为 10 3、375和 6 15 μg/L。盘山、彰武均未发现甲状腺癌患者 ,黄骅则发现 10例甲状腺乳头状癌。 1994年以来 ,黄骅地区甲状腺癌患病率为 91.5 8/ 10万 ,平均年发病率为13 .12 / 10万。结论 高碘地区甲状腺癌发病率高于低碘和适碘地区。
Objective To study the effect of different iodine intakes on the occurrence of thyroid cancer in people aged 14 years or older. Methods Three rural communities in Panshan, Zhangwu and Huanghua were selected as low iodine, suitable iodine, and high iodine areas. Household Survey A total of 22 976 thyroid cancer cases occurred in 3 districts aged ≥ 14 years old, and samples of local urine, urine, drinking water, and edible salt were collected. Results The median urinary iodine was 10 3, 375, and 6 15 μg/L in Panshan, Zhangwu, and Huanghua areas, respectively. No patients with thyroid cancer were found in Panshan and Zhangwu. 10 cases of thyroid papillary carcinoma were found in Huangqi. Since 1994, the prevalence of thyroid cancer in Huanghua has been 91.5 8/100,000, and the average annual incidence rate is 13.12/100,000. Conclusion The incidence of thyroid cancer in high iodine area is higher than that in low iodine and suitable iodine areas.
