目的了解和掌握四川省非克山病病区扩张型心肌病与克山病病区克山病病情现状,为四川省克山病“十二五”的消除考核评估提供可靠科学数据。方法采用描述流行病学方法,收集汇总2011年中财四川省非克山病病区通江县、三台县、棉竹市、古蔺县、长宁县扩张型心肌病和2011年省财克山病病区西昌市、冕宁县、大竹县、仁和区、剑阁县克山病病情调查资料数据,并进行对比分析。结果非病区扩张型心肌病较病区克山病病例搜索诊断病例少,调查任务完成率低,慢型病例检出率低,购外地主食粮食比例高,被调查人群3~20岁少、46~75岁多、男女比例构成高,高血压患病率高,心电检查心电异常率低,P均<0.05,差异有统计学意义;潜在型病例检出率低,人均年收入近千元,X线胸片心脏增大率低,P均>0.05,差异无统计学意义。结论四川省非病区扩张型心肌病与病区克山病病情调查结果经过统计学分析直接或间接验证了克山病营养地球化学病因学说、生物病因学说、克山病流行病学特点及一些影响因素。
Objective To understand and master the status quo of Keshan disease in non-Keshan disease area of Sichuan province and Keshan disease in Keshan disease area, and to provide reliable scientific data for the assessment and evaluation of Keshan disease in Sichuan Province. Methods Descriptive epidemiological methods were used to collect and summarize Zhongcai County, Sichuan Province, Santai County, Mianzhu City, Gulin County, Changning County, dilated cardiomyopathy, Ward Xichang City, Mianning County, Dazhu County, Renhe District, Kian Shan County Keshan disease survey data, and comparative analysis. Results Compared with Keshan disease cases in non-ward, the number of cases diagnosed in Keshan disease was low, the completion rate of investigation tasks was low, the detection rate of chronic cases was low, the proportion of staple foods purchased from outside was high, and the surveyed population was less than 3 to 20 years old. 46 to 75 years old, male to female ratio of high, high prevalence of hypertension, ECG ECG abnormalities were low, P <0.05, the difference was statistically significant; the detection rate of potential cases is low, the average annual income of nearly Thousand yuan, X-ray low cardiac rate, P> 0.05, the difference was not statistically significant. Conclusions The survey results of Keshan disease in non-ward disease and non-ward disease in Sichuan Province, through statistical analysis, directly or indirectly verify the etiology of keshan disease nutrition geochemistry, biological etiology, Keshan disease epidemiology and some Influencing factors.
