目的了解钦州市钦南区2005-2014年丙型病毒性肝炎流行病学特征,为丙肝预防控制策略提供依据。方法从钦州市钦南区传染病信息系统收集2005-2014年报告的丙肝病例,采用描述性流行病学方法,对所获得的资料进行分析。结果 2005-2014年累计报告丙肝病例989例,年平均报告发病率为16.07/10万。2011年发病率最高(27.23/10万),各年发病率的差异有统计学意义(P<0.001);以城区和沿海地区的发病率最高,地区间发病率的差异有统计学意义(P<0.001);标化发病率男性(23.96/10万)高于女性(7.79/10万),比例为3.23∶1,两者发病率差异有统计学意义(P<0.001)。发病率位居前3位分别是30岁~(52.59/10万)、25岁~(39.65/10万)和35岁~(33.56/10万),各年龄组标化发病率差异有统计学意义(P<0.001)。职业分布占比例最大的前3位分别为农民(占32.36%)、家务及待业(占17.99%)和商业服务人员(占5.97%)。结论钦州市钦南区2005-2014年丙肝报告发病率高于全国平均水平,属于丙肝高发地区,需要进一步采取有效的预防控制措施,控制丙肝在本地区高流行的状态。
Objective To understand the epidemiological characteristics of hepatitis C virus in Qinan District, Qinzhou City from 2005 to 2014, and provide the evidence for prevention and control of hepatitis C virus. Methods Hepatitis C cases reported in 2005-2014 were collected from Qinan District Infectious Disease Information System of Qinzhou City. The descriptive epidemiological method was used to analyze the obtained data. Results A total of 989 hepatitis C cases were reported from 2005 to 2014, with an average annual incidence of 16.07 / 100 000. The incidence was highest in 2011 (27.23 / 100000), the incidence of each year was statistically significant (P <0.001); the highest incidence was found in urban and coastal areas, and the incidence of inter-regional differences was statistically significant (P <0.001). The standardized incidence was higher in males (23.96 / 100000) than in females (7.79 / 100000), with a ratio of 3.23:1. There was significant difference in the incidence rates between the two groups (P <0.001). The incidence of the top three were 30 years old to (52.59 / 100000), 25 years old (39.65 / 100000) and 35 years old (33.56 / 100000), the standardized incidence of each age group were statistically significant Significance (P <0.001). The top 3 occupations are farmers (32.36%), household and unemployed (17.99%) and commercial service workers (5.97%), respectively. Conclusions The incidence of hepatitis C in 2005 ~ 2014 in Qinan District, Qinzhou City is higher than the national average. It belongs to the high incidence area of hepatitis C, so effective prevention and control measures need to be taken to control the high prevalence of hepatitis C in this area.
