目的探讨秦皇岛市丙型病毒性肝炎(丙肝)流行规律,为制定预防控制策略提供依据。方法利用国家疾病监测系统中的监测数据,用描述流行病学方法对秦皇岛市2004—2011年的丙肝及相关传染病三间分布资料进行描述和分析。结果 8年中,秦皇岛市和青龙县丙肝发病数呈指数函数增长(R2=0.988 5和R2=0.985 8),二者呈高度正相关,差异有统计学意义(r=1.00,P<0.01)。8年中,年平均发病率秦皇岛市上升9.05倍,青龙县上升46.23倍,2011年秦皇岛市和青龙县发病率分别为22.72/10万和99.85/10万。青龙县丙肝的高发地区主要集中在9个地区,占全县的92.18%。45～75岁为高发年龄。男女性别比为2.17∶1。青龙县乙型肝炎和艾滋病的分布与丙肝不同。结论上世纪末安纳珈注射史仍然是青龙县丙肝流行的主要原因,丙肝流行并未伴随其他血行传播传染病的流行,但是已经构成严重的社会问题,应当引起有关部门重视。
Objective To investigate the prevalence of hepatitis C in Qinhuangdao City and provide evidence for the development of prevention and control strategies. Methods Based on the monitoring data from the national disease surveillance system, epidemiological methods were used to describe and analyze the three distributional data of hepatitis C and related infectious diseases in Qinhuangdao from 2004 to 2011. Results Eight years, the incidence of hepatitis C in Qinhuangdao City and Qinglong County increased exponentially (R2 = 0.988 5 and R2 = 0.985 8), and the two showed a highly positive correlation with a statistically significant difference (r = 1.00, P <0.01) . In 8 years, the annual average incidence of Qinhuangdao City increased 9.05 times, Qinglong County rose 46.23 times. In 2011, the incidence rates of Qinhuangdao City and Qinglong County were 22.72 / 100000 and 99.85 / 100000 respectively. Qinglong County high incidence of hepatitis C are mainly concentrated in nine areas, accounting for 92.18% of the county. 45 to 75 years old for the high incidence of age. The sex ratio of men to women is 2.17: 1. Qinglong County Hepatitis B and AIDS distribution and hepatitis C different. Conclusion Anjiajia injection history is still the main reason of hepatitis C epidemic in Qinglong County at the end of last century. The prevalence of hepatitis C is not associated with the prevalence of other bloodborne infectious diseases, but it has already posed a serious social problem and should be taken seriously by relevant departments.
