（二）临床表现 大多数地方性甲状腺肿病人起病缓慢， 早期仅见甲状腺轻度肿大，多为弥漫性，一 般无明显症状。当甲状腺肿大到一定程度时， 压迫气管和食道可引起呼吸困难和吞咽困难。 肿大的甲状腺压迫喉返神经，可出现声音嘶 哑、痉挛性பைடு நூலகம்嗽等刺激性症状。
22
（三）诊断标准 ▲
我国现行地甲病的诊断标准如下： 1.生活于碘缺乏区（水碘低于10μg／L，尿 碘 低 于 100 μg ／ L ） ； 高 碘 地 区 （ 水 碘 高 于 300μg／L，尿碘高于800 μg／L）；或存在致 甲状腺肿大物质之地区。
地区分布 ：除冰岛外，IDD在世界各国都有不同 程度的流行。主要分布于欧洲阿尔卑斯山脉两侧 国家，北美洲五大湖盆地，南美洲安第斯山脉， 非洲刚果河流域，亚洲喜马拉雅山地区，大洋洲 巴布亚新几内亚一带。最主要的国家有孟加拉、 巴西、中国、印度、印度尼西亚、巴基斯坦、尼 日利亚和俄罗斯，这8个国家占全世界缺碘人口的 54％。一般来说，碘缺乏的表现为山区重于丘陵、 丘陵重于平原、内陆重于沿海。
14
碘缺乏病的主要病因及发病机制
1．营养因素 IDD的发生与不合理的膳食有密切关 系，如低蛋白、低热量的膳食可影响肠道对碘的吸 收，以及甲状腺对碘的吸收和转化。有人发现，某 些病区居民膳食中维生素A、C、B12不足可促使甲 状腺肿发生，这可能是因为维生素是氧化还原酶的 重要组成成分，维生素不足影响了甲状腺激素合成 过程中一系列氧化还原过程。因此，从某种意义讲 IDD是以碘缺乏为主的多种营养素缺乏症。
17
碘缺乏的病因
4. 环境污染物 重金属：铅、汞、铬、锰等 有机氯农药：六六六、DDT PCB 硝酸盐
18
临床表现
地方性甲状腺肿（endemic goiter），简称 地甲病，其主要症状是甲状腺肿大。
