[目的]了解东营市乙型病毒性肝炎(乙肝)的流行特征及其变化,为今后防治工作提供参考依据。[方法]采用描述流行病学方法对2004～2011年东营市乙肝疫情监测资料进行分析。[结果]2004～2011年东营市共报告乙型肝炎8 760例,年均发病率为58.45/10万,发病率呈逐年下降趋势;各县区年均发病率差异有统计学意义(P<0.01),男女性年均发病率的差异有统计学意义(P<0.01)。2007～2011年发病率平均每年下降速度比2004～2006年增快;月发病数的中位数呈逐年下降趋势;16～50岁人群的发病例数和发病率均呈现逐年下降趋势;发病无明显地域性和季节性;以青壮年为主,男性多于女性;以农民发病最多。[结论]为乙肝感染高危人群接种疫苗对发病率的降低起了重要作用;男性青壮年应成为乙肝防治的重点人群;预防乙肝应加强对成年高危人群和重点人群的疫苗接种工作。
[Objective] To understand the epidemiological characteristics and changes of hepatitis B virus in Dongying city and provide references for future prevention and treatment. [Methods] The descriptive epidemiological method was used to analyze the surveillance data of hepatitis B in Dongying City from 2004 to 2011. [Results] A total of 8 760 hepatitis B cases were reported in Dongying City from 2004 to 2011, with an average annual incidence rate of 58.45 / 100 000. The incidence rate showed a declining trend year by year. The annual average incidence rates in all counties were statistically significant (P < 0.01), the average annual incidence of male and female were statistically significant (P <0.01). The average annual incidence rate of incidence in 2007-2011 increased faster than that of 2004-2006. The median of monthly incidence showed a declining trend year by year. The incidence and incidence of cases aged 16-50 decreased year by year. The incidence was no Significantly regional and seasonal; young and middle-aged, more men than women; incidence of peasants up. [Conclusion] Vaccination for high-risk population of hepatitis B infection plays an important role in reducing the incidence. Male young and middle-aged should be the key population for prevention and treatment of hepatitis B. Vaccination should be strengthened for high-risk adults and key populations in prevention of hepatitis B.
