目的分析襄阳市襄州区2007—2013年病毒性肝炎的流行现状,为制定肝炎防制策略提供科学依据。方法对2007—2013年襄州区病毒性肝炎疫情资料进行描述性流行病学分析。结果襄州区7年间共报告病毒性肝炎4 246例(其中乙型肝炎3 578例,占84.27%),年均发病率为62.01/10万,发病率最高年份为2007年(92.35/10万),最低为2012年(39.38/10万)。病毒性肝炎发病无明显季节性,城区发病率(137.69/10万)高于农村地区(51.57/10万),差异有统计学意义(P<0.01);发病年龄以20~59岁年龄组人群为主,共3 154例(占74.28%);男性发病率(79.72/10万)高于女性(43.55/10万),差异有统计学意义(P<0.01);职业分布以农民居多,共2 364例(占55.68%),其次是家务及待业,共430例(占10.13%)。结论襄阳市襄州区2007—2013年病毒性肝炎发病率呈下降趋势,应针对不同人群的危险因素制定病毒性肝炎进一步的防制策略。
Objective To analyze the prevalence of viral hepatitis in Xiangzhou District of Xiangyang City from 2007 to 2013 and provide a scientific basis for the development of hepatitis prevention and control strategies. Methods Descriptive epidemiological analysis of the epidemic situation of viral hepatitis in Xiangzhou District from 2007 to 2013 was conducted. Results A total of 4 246 cases of viral hepatitis (3 578 cases of hepatitis B, accounting for 84.27%) were reported in Xiangzhou District during the 7 years. The average annual incidence was 62.01 / 100 000 with a highest incidence rate of 92.35 / 100 000 in 2007 ), The lowest for 2012 (39.38 / 100,000). The incidence of viral hepatitis was not significantly seasonal, the incidence of urban area (137.69 / 100000) was higher than that of rural areas (51.57 / 100000), the difference was statistically significant (P <0.01); the age of onset was 20-59 years old , With a total of 3 154 cases (accounting for 74.28%). The incidence of males was 79.72 / 100000 higher than that of females (43.55 / 100000), the difference was statistically significant (P <0.01) 2 364 cases (accounting for 55.68%), followed by domestic work and unemployed, a total of 430 cases (10.13%).
