目的分析2001—2010年湖北省武汉市戊型肝炎(戊肝)的发病情况和变化趋势。方法采用描述性流行病学方法和线性相关分析。结果 2001—2010年武汉市报告戊肝5 011例,年均发病率为6.20/10万;戊肝发病率呈先升高后下降的趋势(χ2=836.53,P<0.001),但发病率仍维持在较高水平,戊肝常年散发,无明显的季节性,但冬春季发病相对较多;年均发病率中心城区高于远城区(χ2=1 284.65,P<0.001),戊肝发病率随着年龄增加呈上升趋势(r=0.816,P<0.001),55～84岁发病率较高,男性高于女性(χ2=848.01,P<0.001);在总病例中,离退休人员占28.46%,其次是工人占16.74%。结论近年武汉市戊肝发病率较高,中心城区是高发区,男性、离退休人员、>50岁中老年人是发病的重点人群。
Objective To analyze the incidence and change trend of hepatitis E (hepatitis E) in Wuhan from 2001 to 2010 in Hubei province. Methods Descriptive epidemiological methods and linear correlation analysis were used. Results In Wuhan City from 2001 to 2010, 5 011 cases of hepatitis E were reported, with an average annual incidence of 6.20 / 100,000. The incidence of hepatitis E increased first and then decreased (χ2 = 836.53, P <0.001), but the incidence was still (P <0.001). The incidence of hepatitis E was significantly higher than that in the urban areas (χ2 = 1284.65, P <0.001), and the prevalence of hepatitis E was higher than that of the urban areas (R = 0.816, P <0.001). The prevalence was higher in 55-84 years old than in women (χ2 = 848.01, P <0.001). Among the total cases, retirees accounted for 28.46 %, Followed by workers accounted for 16.74%. Conclusion The prevalence of hepatitis E in Wuhan is high in recent years. The central urban area is a high prevalence area, male and retired people, and the middle-aged and elderly people aged> 50 are the key patients.
