摘　　要：目的分析2012—2023年甘肃省丙型病毒性肝炎(简称“丙肝”)的流行病学特征并对2024—2025年的丙肝发病趋势进行预测,为居民丙肝防治策略的制定提供参考依据。方法收集中国疾病预防控制信息系统传染病报告信息管理系统中甘肃省2012年1月1日—2023年12月31日报告的丙肝发病数据,对甘肃省丙肝发病的流行病学特征进行描述性分析,并应用GM(1,1)模型和曲线回归模型对丙肝年发病数进行拟合,选择最优模型预测2024—2025年甘肃省居民的丙肝发病趋势。结果2012—2023年甘肃省共报告丙肝发病83306例,年均发病率为26.53/10万;2012、2013、2014、2015、2016、2017、2018、2019、2020、2021、2022和2023年丙肝发病率依次为34.93/10万、29.10/10万、25.87/10万、30.21/10万、24.28/10万、29.71/10万、29.47/10万、28.04/10万、23.40/10万、22.49/10万、19.62/10万和21.29/10万,2012—2023年丙肝发病率总体呈下降趋势(χ趋势2=458.167,P=0.006),年均下降率为1.13%。甘肃省2012—2023年不同地区丙肝年均发病率差异有统计学意义(χ^(2)=431.086,P=0.007),居于前3位的地区分别为武威市、张掖市和兰州市,丙肝年均发病率依次为96.78/10万、63.62/10万和34.13/10万。甘肃省2012—2023年男性人群丙肝年均发病率(31.27/10万)高于女性人群(19.36/10万),差异有统计学意义(χ^(2)=307.512,P=0.008);不同年龄人群丙肝年均发病率差异有统计学意义(χ^(2)=53.104,P=0.007),其中以45~54岁人群丙肝年均发病率最高(46.13/10万);居于丙肝发病首位的职业为农民,2012—2023年共报告丙肝发病53716例,占总发病数的64.48%。对2种模型进行比较发现,GM(1,1)模型的平均绝对误差(MAE)和平均相对误差(MAPE)分别为525.3和0.06%,均低于二次曲线回归模型MAE和MAPE的551.0和0.07%,GM(1,1)模型的拟合效果更好,该模型预测的甘肃省2024和2025年丙肝发病数分别为5051和4789例,丙肝发病呈下降趋势。结论2012—Objective To analyze the epidemiological characteristics of hepatitis C incidence and incidence trend from 2012 to 2023 and predict the incidence for 2024–2025 in Gansu province for the development of hepatitis C prevention and control strategies among local residents.Methods Data on hepatitis C incidence reported in Gansu province from 2012 to 2023 were collected from the Infectious Disease Reporting Information Management System of the Chinese Center for Disease Control and Prevention.A descriptive analysis of the epidemiological characteristics of hepatitis C incidence in Gansu province was conducted,and both the GM(1,1)model,linear and nonlinear curve regression analysis were performed to fit the annual incidence of hepatitis C.The optimal model was selected to predict the incidence of hepatitis C incidence for 2024–2025 among residents of Gansu province.Results During the 12-year period,a total of 83306 hepatitis C cases were reported in Gansu province,with an average annual incidence rate(1/100000)of 26.53 and annual specific incidence rates of 34.93,29.10,25.87,30.21,24.28,29.71,29.47,28.04,23.40,22.49,19.62,and 21.29 for the years from 2012 to 2023,respectively.There was an overall downward trend in the hepatitis C incidence rate during this period(χ^(2)trend=458.167,P=0.006),with an average annual decrease of 1.13%.The average annual incidence rate of hepatitis C varied significantly among different regions of the province(χ^(2)trend=431.086,P=0.007),with the top three average annual incidence rates of 96.78,63.62,and 34.13 for Wuwei,Zhangye,and Lanzhou municipalities.The average annual incidence rate of hepatitis C for the male population(31.27)was significantly higher than that for the female population(19.36)(χ^(2)=307.512,P=0.008)and the rate differed significantly among the populations of different age groups(χ^(2)trend=53.104,P=0.007),with the highest rate(46.13)for the population aged 45–54 years.The majority of the hepatitis C cases reported during the period(51928,64.48%of the total)we
