摘要:

目的 分析成都市乙型病毒性肝炎(简称乙肝)流行趋势变化,为科学防控乙肝提供参考。方法 通过中国疾病预防控制信息系统收集2005—2024年成都市乙肝病例资料,对其流行特征进行描述性分析,对报告发病率趋势进行Joinpoint回归分析。结果 2005—2024年成都市累计报告乙肝病例132 880例,年均报告发病率为43.78/10万,以慢性乙肝病例为主(111 365例,占83.81%)。2005—2024年成都市急性、未分类乙肝报告发病率均呈下降趋势(AAPC=-11.850%、-21.265%,95%CI:-14.092%~-9.550%、-27.001%~-15.078%,P均<0.05),慢性乙肝报告发病率呈上升趋势(AAPC=6.923%,95%CI:4.154%~9.242%,P<0.05)。不同人群中,男性乙肝报告82 655例、女性报告50 225例,年均报告发病率分别为53.99/10万、33.39/10万;14岁及以下人群乙肝报告发病率最低(3.33/10万),65~74岁人群乙肝报告发病率最高(58.74/10万);农民报告病例数最多(53 159例,占40.01%)。不同地区中,中心城区报告病例数较多(77 983例,占58.69%),县市新城报告发病率较高(49.57/10万)。结论 2005—2024年成都市急性、未分类乙肝发病率均呈下降趋势,慢性乙肝发病率呈上升趋势。现存病例以慢性乙肝为主,发病人群以男性、农民较为多见,建议针对此类重点人群开展健康教育和重点筛查。

Abstract:

ObjectiveTo analyze the changes in epidemic trends of viral hepatitis B (hereinafter referred to as hepatitis B) in Chengdu City for a reference for scientific prevention and control of hepatitis B virus infection. Methods Data on hepatitis B cases in Chengdu City from 2005 to 2024 were retrieved from the Chinese Disease Prevention and Control Information System. The epidemiological characteristics and the incidence trend were analyzed respectively by descriptive epidemiology and Joinpoint regression model. Results A total of 132 880 hepatitis B cases were reported in Chengdu City between 2005 and 2024, with an average annual incidence rate of 43.78 per 100 000 population. Chronic hepatitis B cases were dominant, accounting for 83.81% (111 365 cases). The incidences of acute and unclassified hepatitis B showed declining trends (AAPC=-11.850% and -21.265%, 95%CI: -14.092% to -9.550% and -27.001% to -15.078%, both P<0.05), whereas chronic hepatitis B presented an increasing trend (AAPC=6.923%, 95%CI: 4.154% to 9.242%, P<0.05). By population subgroups, 82 655 cases were males and 50 225 were females, with annual average incidence of 53.99/100 000 and 33.39/100 000, respectively. The reported incidence was the lowest in the population aged 14 years and under (3.33/100 000) and the highest in those aged 65?74 (58.74/100 000). Farmers constituted the largest occupational group (53 159 cases, 40.01%). Among different regions, the central urban area reported more cases (77 983 cases, 58.69%), while new county?level cities and districts had higher reported incidence (49.57/100 000). Conclusion From 2005 to 2024, the incidences of acute and unclassified hepatitis B in Chengdu City exhibited a declining trend, while chronic hepatitis B incidence showed an increasing trend. Existing cases are predominantly chronic hepatitis B, with higher prevalence in males and farmers. It is recommended to implement health education and targeted screening for these key populations.
