目的分析2006-2015年江苏省急性乙肝发病率的变化趋势,为乙肝的防控工作提供科学依据。方法采用描述流行病学方法对2006-2015年江苏省急性乙肝数据进行统计分析,资料来源于《中国疾病预防控制信息系统》。结果江苏省2006-2015年共报告28 521例急性乙肝病例,年均发病率为3.70/10万,急性乙肝发病率总体呈下降趋势(χ~2=3 378.40,P<0.001),男女发病比为2.80∶1,发病年龄集中在20~60岁,职业为农民(14 458例,占50.69%)、工人(3 905例,占13.69%)的发病较多。结论江苏省急性乙肝发病率低于全国平均水平(4.70/10万),属于急性乙肝低发病率地区,本省乙肝疫苗的接种人群效果显著。今后应继续做好急性乙肝的防控工作,加强宣传教育,提高成人(>20岁)乙肝疫苗接种率。
Objective To analyze the change trend of the incidence of acute hepatitis B in Jiangsu Province from 2006 to 2015 and provide a scientific basis for the prevention and control of hepatitis B. Methods A descriptive epidemiological method was used to analyze the data of acute hepatitis B in Jiangsu Province from 2006 to 2015. The data were obtained from China Disease Prevention and Control Information System. Results A total of 28 521 cases of acute hepatitis B were reported from 2006 to 2015 in Jiangsu Province, with an average annual incidence of 3.70 / 100 000. The incidence of acute hepatitis B generally showed a decreasing trend (χ ~ 2 = 3 378.40, P <0.001) The incidence was concentrated in the range of 20 to 60 years. The occupations were farmers (14 458, accounting for 50.69%) and workers (3 905, accounting for 13.69%). Conclusions The incidence of acute hepatitis B in Jiangsu Province is lower than the national average (4.70 / 100,000), which belongs to the low incidence of acute hepatitis B, and the effect of hepatitis B vaccine vaccination in this province is remarkable. In the future, prevention and control of acute hepatitis B should be continued and publicity and education should be stepped up to increase the rate of hepatitis B vaccination among adults (> 20 years old).
