目的:分析钦州市钦南区2005-2014年报告乙型病毒性肝炎(乙肝)流行病学特征,为乙肝预防控制策略提供依据。方法:采用描述性流行病学方法,对2005-2014年中国疾病预防控制信息系统网络报告的乙肝病例的流行病学特征进行分析。结果:2005-2014年钦州市钦南区累计报告乙肝病例4 279例,各年发病率相对波动在62~89/10万之间,没有大幅度的上升或下降,年平均报告发病率为73.59/10万;15岁以下人群发病率较低,由2005年23.35/10万下降到2014年4.09/10万,下降趋势显著。20~39岁青壮年发病率最高;男性发病率(91.84/10万)明显高于女性(42.17/10万)。农民病例数占最多(42%)。在报告病例中,以慢性乙肝为主(75.84%),急性乙肝占11.40%。结论:钦州市钦南区2005-2014年乙肝报告发病率低于全国及广西,自2005年6月1日起实施新生儿接种乙肝疫苗免费策略之后,15岁以下人群发病率大幅下降,收到显著的预防效果。今后须要进一步探索成人乙肝免疫策略。
Objective: To analyze the epidemiological characteristics of hepatitis B virus (HBV) from 2005 to 2014 in Qinan District, Qinzhou City, and provide evidence for its prevention and control strategy. Methods: Descriptive epidemiological methods were used to analyze the epidemiological characteristics of hepatitis B cases reported by China CDC network in 2005-2014. Results: A total of 4 279 hepatitis B cases were reported in Qinan District of Qinzhou City from 2005 to 2014, with a relative fluctuation of 62-89 / 100 000 in each year without any significant increase or decrease. The annual average incidence was reported as 73.59 / 100,000; the incidence of people under the age of 15 is relatively low, from 23.35 / 100,000 in 2005 to 4.09 / 100,000 in 2014, showing a significant downward trend. The highest incidence of young adults aged 20 to 39 years; male incidence (91.84 / 100000) was significantly higher than the female (42.17 / 100000). The largest number of farmers (42%). In the reported cases, mainly chronic hepatitis B (75.84%), acute hepatitis B accounted for 11.40%. Conclusion: The incidence of hepatitis B in 2005-2004 in Qinan District of Qinzhou City is lower than that of the whole country and Guangxi. Since June 1, 2005, the incidence of hepatitis B vaccine has dropped dramatically since the implementation of the newborn vaccination strategy. Significant preventive effect. In the future, we need to further explore adult hepatitis B immunization strategies.
