目的探讨滨州市病毒性肝炎发病情况及流行特征,为更好地制定防控措施提供依据。方法采用描述性流行病学方法分析滨州市2005-2011年病毒性肝炎疫情资料,分析软件采用SPSS 18.0和Excel。结果滨州市2005-2011年病毒性肝炎发病率整体呈下降趋势,年平均发病率为45.71/10万;乙肝年均发病率最高(42.97/10万),戊肝最低(0.35/10万)。病原学分型以乙肝为主,且发病比例呈上升趋势;未分型肝炎发病比例呈逐年下降趋势,甲肝、丙肝及戊肝发病比例呈上下波动趋势。发病年龄集中在15~64岁,各型肝炎高发年龄有所不同。男性发病率高于女性(χ2=2506.593,P<0.001)。结论病毒性肝炎发病率呈下降趋势,但仍保持较高水平,防控工作有待进一步加强。
Objective To explore the incidence and epidemic characteristics of viral hepatitis in Binzhou and provide the basis for better prevention and control measures. Methods Descriptive epidemiological method was used to analyze the epidemic situation of viral hepatitis in Binzhou from 2005 to 2011. The software was analyzed by SPSS 18.0 and Excel. Results The overall incidence of viral hepatitis in Binzhou decreased from 2005 to 2011 with an average annual incidence of 45.71 / 100 000; the annual average incidence of hepatitis B was 42.97 / 100 000 and that of hepatitis E was the lowest (0.35 / 100 000). The pathogenic type was mainly hepatitis B, and the proportion of the incidence was on the rise. The incidence of non-typed hepatitis showed a declining trend year by year. The incidence of hepatitis A, C and E showed upward and downward fluctuations. The age of onset concentrated in the 15 to 64 years old, high incidence of various types of hepatitis is different. The incidence of males was higher than that of females (χ2 = 2506.593, P <0.001). Conclusions The incidence of viral hepatitis shows a downward trend, but it remains at a high level and prevention and control work needs to be further strengthened.
