目的分析2018—2023年大理白族自治州(简称大理州)丙型病毒性肝炎(简称丙肝)的流行病学特征,了解大理州丙肝疫情流行状况,为有效制定防控措施及策略提供参考依据。方法收集中国疾病预防控制信息系统中大理州2018—2023年丙肝报告病例数据,运用描述流行病学方法分析其流行特征,应用SPSS 27.0软件进行χ2检验。结果 2018—2023年大理州累计报告丙肝病例4 362例,死亡360例,年均报告发病率为21.31/10万,不同年份丙肝发病率差异有统计学意义(χ2=84.807,P<0.001)。从时间分布看,8月累计报告病例最多,1、2月最少,2018—2023年集中度M=0.075,季节性较弱。丙肝高发地区集中在大理市(2 202例,50.48%)、弥渡县(483例,11.07%)、宾川县(379例,8.69%),2018—2023年大理州报告发病数年平均增长率为7.55%,年均增长幅度居前3位的是云龙县、剑川县和巍山县。在4 362例报告病例中,男性3 216例,女性1 146例,男女性别比为2.81∶1;丙肝发病以青壮年为主,40～＜50岁年龄组报告病例数最多(1 860例,42.64%);发病人群职业分布主要集中在农民(3 342例,76.62%)和家务及待业(360例,8.25%)。结论 2018—2023年大理州丙肝发病率总体呈上升趋势,季节性较弱,40～＜50岁、男性、农民是丙肝重点发病人群。

Abstract

Objective To analyze the epidemiological features of viral hepatitis type C(hepatitis C for short) in Dali Bai autonomous prefecture (Dali prefecture for short) from 2018 to 2023, to understand the prevalence of hepatitis C in Dali prefecture, and to provide a reference basis for effectively formulating hepatitis C prevention and control measures and strategies. Methods We collected the data on hepatitis C cases reported in Dali prefecture during 2018-2023 from the Information System for China Disease Control and Prevention. Descriptive epidemiological methods were employed to describe the epidemiological characteristics of hepatitis C cases in Dali prefecture. χ2 test was performed by using SPSS 27.0 software. Results A total of 4,362 cases of hepatitis C were cumulatively reported in Dali prefecture from 2018 to 2023, with 360 deaths and the average annual reported incidence rate being 21.31/100,000. There were statistically significant differences in the incidence rate of hepatitis C among different years (χ2=84.807, P<0.001). In terms of time distribution, the cumulative number of reported cases was the highest in August, but the lowest in January and February. The concentration ratio(M) in 2018-2023 was 0.075, indicating weak seasonality. The areas with high incidence of hepatitis C were concentrated in Dali city (n=2,202, 50.48%), Midu county (n=483, 11.07%), and Binchuan county (n=379, 8.69%). The average annual growth rate of the reported cases in Dali prefecture from 2018 to 2023 was 7.55%, with the top three average annual increases in Yunlong, Jianchuan and Weishan counties. Among the 4,362 reported cases, there were 3,216 males and 1,146 females, with a male-to-female ratio of 2.81∶1. Hepatitis C primarily affects young and middle-aged adults, with the highest number of cases reported in the group aged 40-<50 years (n=1,860, 42.64%). Occupational distribution displayed that most of the cases were farmers (n=3,342, 76.62%) and house worker or the unemployed (n=360, 8.25%). Conclusions The incidence rate of hepatitis C in Dali prefecture from 2018 to 2023 showed an overall upward trend, with weak seasonality. Individuals aged 40-<50 years, males and farmers are keypopulations affected by hepatitis B.
