目的分析克山病基本控制后平邑县克山病病情及发病相关因素,为克山病病情预测及卫生行政管理与科学研究提供依据。方法选择武台镇、流峪镇、白彦镇和平邑镇的克山病历史发病村设立观察点,1990年起连续观察至2008年,1990~1999年以3~14岁多发人群和14岁以上可疑人群为观察对象。2006~2008年以全年龄组人群为观察对象。对全部观察对象进行临床查体和描记心电图,对可疑病例拍X线胸片,随机采集头发、小麦、玉米和地瓜干进行硒含量测定,同时调查居民经济收入和人均占有粮食量。结果9年共观察人群4 238人次,克山病检出率在0.42%~3.67%之间;共检出异常心电图189例,总异常心电图检出率为4.46%;头发硒水平逐年升高,粮食硒含量水平基本恒定;经济收入与人均占有粮食量显著增加。结论达到克山病基本控制标准后,平邑县克山病病情呈基本稳定态势,与发病相关因素不断改善有重要关系。
Objective To analyze the condition and related factors of Keshan disease in Pingyi county after the basic control of Keshan disease, and to provide basis for the prediction of Keshan disease and health administration and scientific research.
