摘要
目的了解四川省棘球蚴病人群患病的变化情况。方法分别于2012年(以下简称"第1次")采用分层抽样调查和2015—2018年(以下简称"第2次")采用普查方法调查四川省35个棘球蚴病流行县人群患病情况。结果第1次调查112605人,确诊患者1311例,患病率为1.16%;第2次调查2744413人,确诊患者11924例,患病率为0.43%,两次调查均以甘孜州患病率最高,分别为1.59%(925/58121)和0.95%(10754/2744413);两次调查人群男女构成及年龄分布,存在一定差异,差异均有统计学意义(性别构成比:χ^(2)=203.338,P<0.001;年龄分布:χ^(2)=14619.868,P<0.001);第1次调查人群患病主要以CE为主,CE、AE标化患病率分别为0.84%和0.26%,第2次调查人群患病以AE为主,CE、AE患病率分别为0.21%(5737/2744413)和0.23%(6262/2744413),不同病灶类型棘球蚴病患病率均明显下降(CE:χ^(2)=10361.32,P<0.001;AE:χ^(2)=59.142,P<0.001);第1次调查男性和女性标化患病率分别为0.47%和0.65%,第2次调查男性和女性患病率分别为0.36%(4882/1353375)和0.5%(7012/1391038);不同性别棘球蚴病患病率均明显下降(男性:χ^(2)=3591.11,P<0.001;女性:χ^(2)=4711.20,P<0.001);两次调查均以0~19岁组患病率最低,分别为0.89%和0.15%,60~79组最高,分别为1.95%和0.83%,各年龄组人群棘球蚴病患病率均明显下降。结论由于诊断水平的提高和防治项目的强力实施,四川省棘球蚴病患者得到有效的诊治,人群患病情况有了较大的改善。
Objects To analyze the changes in prevalence of echinococcosis in Sichuan Province in2012 and 2015 to 2018.Methods A stratified sampling method was used to investigate the prevalence of echinococcosis in 35 hydatid-endemic counties in Sichuan Province in 2012(the first time)and 2015 to 2018(the second time).Results In 2012 survey,112605 people were screened for echinococcusis infection by using abdominal B-type altrasonograph,and 1311 confirmed patients were found with a prevalence rate of 1.16%.In 2015 to 2018 survey,a total of 2744413 people were screened,and 11924 confirmed patients were diagnosed,with a prevalence rate of 0.43%.In the two surveys,the prevalence rate was the highest in Garze Tibetan autonomous prefecture,with a prevalence rate of 1.59%(925/58121)in 2012 survey and 0.95%(10754/2744413)in 2015 to2018 survey.There were significant differences in sex composition and age distribution in two surveys(sex ratio:χ^(2)=203.338,P<0.001;age distribution:χ^(2)=14619.868,P<0.001).In the first survey,the proportion of cystic echinococcosis(CE)was in dominant.The standardized prevalence rates of CE and alveolar echinococcosis(AE)in human were 0.84%and 0.26%,respectively.In the second survey,the number of AE cases was preponderating.The prevalence rates of CE and AE were 0.21%(5737/2744413)and 0.23%(6262/2744413),respectively.The prevalence of echinococcosis of different types decreased significantly(CE:χ^(2)=10361.32,P<0.001;AE:χ^(2)=59.142,P<0.001).The standardized prevalence rates of echinococcosis in males and females were 0.47%and 0.65%,respectively.In the second survey,the prevalence rates of echinococcosis in males and females were 0.36%(4882/1353375)and 0.5%,respectively(7012/1391038).The prevalence rates of echinococcosis in different genders decreased significantly(males:χ^(2)=3591.11,P<0.001;females:χ^(2)=4711.20,P<0.001).In the two surveys,the lowest prevalence was in age group less than 20 years,with prevalence rates of 0.88%in first survey and 1.92%in second survey.The highest prevalence was observed in the group aged 60 years and above,with prevalence rates of 0.88%in first survey and 1.92%in second survey.In the first survey,the prevalence rates in teenagers less than 19 years and adults aged over 60 years were 0.15%and 0.83%,respectively.The prevalence of echinococcosis in all age groups decreased significantly.Conclusion Due to the improvement of the diagnosis level and the implementation of the control project,almost all patients have been effectively diagnosed and treated,and the prevalence of echinococcosis has been decreased.
