目的观察克山病病情及发病相关因素的动态变化,为指导克山病防治研究提供科学依据。方法选取克山病病区为监测点,按照《全国克山病监测方案》要求,自2008年～2012年对监测点常住人口进行病例搜索和病情监测。包括临床查体、心电图描记、疑似病例心脏后前位X线摄片,同时调查经济收入和主食情况。结果 5年间共搜索6个县(市),170个医疗机构,克山病受检人数5 627人,检出克山病62例,总检出率1.10%。X线胸片检查281例,心电图描记5 627例,检出的病人均为慢型和潜在型,未发现急型和亚急型病人。结论克山病病区居民病情处于稳定态势,在国家病区控制标准之内。居民经济收入增加膳食明显改善,内环境硒含量水平升高是重要环境因素。
