Dynamic analysis on monitoring results of Keshan disease in Shandong Province for 15 years

目的动态观察山东省15年克山病病情变化,掌握克山病的消长趋势,科学指导防治工作。方法按照全国克山病监测方案要求,自1990年在克山病重病区设立监测点,对3～14岁易患人群及14岁以上可疑患者进行连续病情监测,同时调查内外环境硒含量、居民经济收入及人均占有粮食等情况。结果山东省连续15年4个监测点区县无急型、亚急型克山病发病,慢型克山病发病37例;重点检测人群克山病检出率在1.85%～4.23%之间,其中81.30%～94.60%为潜在型克山病人;异常心电图和X线胸片心脏扩大检出率分别是2.10%～5.71%和14.10%～23.60%;发硒含量有增加趋势。结论山东省克山病病情处于基本控制后的持续稳定状态。

Objective This study was designed to observe dynamically the change of conditions of Keshan disease in the past 15 years in Shandong Province, to understand the changing trend of Keshan disease, and so scientifically instruct the implementation of prevention, control and research work. Methods According to the requirements of national monitoring measures for Keshan disease, the areas with high incidence of Keshan disease were set monitoring point since 1990, and a continuous monitoring for conditions of susceptible people aged 3-14 years and suspected patients above 14 years old was conducted, and at the same time, the content of selenium in inside and outside environment, as well as the economic income of resident and per capita available provisions, etc. was investigated. Results There was no case of acute or sub-acute Keshan disease observed at the four monitoring points for continuous 15 years, while there were 37 cases of chronic Keshan disease. The detectable rate among people mainly monitored was 1.85% to 4.23%, of which 81.30% to 94.60% were potential patients of Keshan disease. The detectable rate for abnormal electrocardiogram and heart enlargement found through chest X-ray examination was 2.10%-5.71% and 14.10%-23.60% respectively. The content of hair selenium tended to increase. Conclusion The Keshan disease conditions of Shandong Province were in a continuous stable state after controlled basically.
