2009年四川省克山病调查

Analysis of Keshan Disease in Sichuan,2009

目的了解四川省克山病病区现状,为四川省克山病预防控制提供科学依据。方法按统一调查方案对选定的冕宁县、西昌市、大竹县等12县的调查点内3～70岁常住人口进行问卷调查,临床查体,描记12导联心电图,疑似病例摄2 m后前位X线胸片,调查当地补硒干预措施,用原子荧光法测定人群发硒和家庭主食粮食硒的含量。结果 12县(市)调查点调查8 198人,检出慢型和潜在型克山病共69例,总检出率为0.84%(69/8 198),其中慢型克山病25例,检出率0.30%(25/8 198),潜在型克山病44例,检出率0.54%(44/8 198),未发现急型和亚急型克山病例。病区居民头发硒均值0.306 7μg/g,粮食硒均值<0.01 mg/kg的样品比例50.8%。结论 2009年四川省调查点克山病检出率较低,病区居民发硒、粮硒检出较低。

Objective To understand the prevalence of Keshan disease（KD） in Sichuan and provide evidence for the prevention and treatment of KD.Method Based on the uniform surveillance program,the residents who were 3-70 years old in 12 counties including Mianning,Xichang and Dazhu were surveyed.The factors potentially related with KD were also surveyed.Results Totally 8 198 residents in 12 surveillance sites were surveyed.Sixty nine cases were detected（0.84%）,including 25 chronic cases（0.30%） and 44 latent cases（0.54%）.No acute and sub-acute cases were detected.The average selenium level of hair was 0.3067 mg/kg.The rate of the food with selenium level 0.01 mg/kg was 50.8%.Conclusions The detection rate of KD was low in Sichuan in 2009,and the detection rates of selenium in Hair and food were also low.
