摘　　要：目的分析甘肃省丙型肝炎(丙肝)的流行特征及规律,为进一步控制丙肝疫情提供参考信息。方法采用描述流行病学方法,分析2008-2017年甘肃省丙肝病例流行病学特征,采用SPSS 20.0软件进行统计分析,率的比较采用χ^2检验。结果共报告丙肝病例72899例,发病总体呈上升趋势(χ^2=1330.472,P<0.01),2012年丙肝报告发病率达到高峰,为34.93/10万;男女性比为1.08~1.83∶1。20~49岁年龄组累计报告病例数占42.94%,并逐年下降;≥50岁年龄组病例报告发病率总体呈上升趋势(χ^2=1342.154,P<0.05),且女性报告病例数所占比例呈上升趋势;农民35919例,占49.27%,且病例数逐年上升;全年各月均有发病,发病率在1/10万~3/10万波动;兰州、武威市丙肝发病率高于其他地区。结论甘肃省丙肝发病率总体呈上升趋势,无明显季节性波动,地区分布差异有统计学意义,发病率随年龄增加呈上升趋势,需加强对重点人群和地区的疫情监测。Objective To analyzed the epidemiological characteristics of hepatitis C in Gansu province and provide scientific evidence for the improvement of prevention and control of hepatitis C.Methods The incidence data of hepatitis C in Gansu from 2008 to 2017 were collected for a descriptive epidemiological analysis.The statistical analysis was done with software SPSS 20.0 and the rate comparison was through χ^2 test Results A total of 72 899 cases of hepatitis C were reported in Gansu during this period.The incidence rate of hepatitis C showed an increase trend from 20.92/100 000 to 29.71/100 000(χ^2=1 330.472,P<0.01) and reached peak of 34.93/100 000 in 2012.The male to female ratios of the cases were 1.08∶ 1 and1.83∶ 1 respectively.The cumulative case number in age group 20–49 years accounted for 42.94% of the total,showing a decrease trend.The reported incidence rate in age group ≥50 years increased year by year(χ^2=1 342.154,P<0.05),The proportion of the cases reported in women showed an increase trend.The cases in farmers accounted for 49.27%(35 919 cases)and increased with year.Hepatitis C occurred all the year round.The incidence rates ranged from 1/100 000 to 3/100 000.The incidence rates of hepatitis C in Wuwei and Lanzhou were higher than those in other areas.Conclusion The overall incidence of hepatitis C in Gansu was in increase without obvious seasonality.The difference in incidences among different areas was significant,and the incidence rate increased with age.It is necessary to strengthen the surveillance for hepatitis C in key populations and areas.
