目的分析云南不明原因心源性猝死的分布特点,探索危险因素,为制定切实有效的防治措施提供科学依据。方法根据《云南不明原因心源性猝死回顾性调查方案》,采用统一的调查表,收集病例信息进行统计分析。结果1.从1975年以后几乎每年都有病例,且每3-4年出现一个发病高峰,发病时间主要集中在每年的7,8月份;2.病区主要分布在经济、卫生状况较差的山区、半山区;3.发病具有明显的时间和空间聚集性;4.各个年龄段均有发病,但以青壮年人群为主;5.在研究对象中,既往服硒的病例所占的比例较少(2.5%)。结论云南不明原因心源性猝死发病具有明显的聚集性(家庭、村庄和时间聚集性),该病已成为一个严重的公共卫生问题,需要进一步探索研究。
Objective To analyze the epidemiological characteristics of unexpected sudden cardiac deaths ( USCD) in Yunnan and to provide scientific evidence for the disease prevention and control. Methods According to "The Project of USCD Retrospective Investigation", the information of each case was collected. Results 1. There had been some cases every year since 1975. The occurrence was regular. It presented a peak per 3 to 4 years. The disease mainly occurred in July and August. 2. The cases with USCD were mainly found in high mountainous areas and the living levels of them were below the standard. 3. There was time - space clustering of USCD in families and villages. 4. There is no difference of occurrence in age, but mainly in the young people. 5. Percentage of the cases taking sodium selenite was 2.5%. Conclusions There is extreme time - space clustering of USCD in families and villages. It has become a serious public health problem and needs further studies.
