更多Objective To determine the epidemiological characteristics of hepatitis B infection among people of 15 years old or over from 2006 to 2015 in Yinzhou district,Ningbo,and to provide the evidence for prevention and control of hepatitis B virus infection in adults.Methods The descriptive epidemiological method was used to analyze the data of case information during 2006 and 2015 collected from the National Disease Surveillance and Report System.Results There were 1 664 hepatitis B cases among people of 15 years old or over in Yinzhou from 2006 to 2015 of an annual average incidence rate of 11.50 per 100 000.The incidence rates each year ranged from 8.22/100 000 to 13.87/100 000,with a general decreasing trend (x2mend=5.492,P<0.05).The incidence of acute hepatitis B decreased (x2mend=122.229,P<0.01) annually,while the incidence of chronic hepatitis B increased (x2mend=14.792,P<0.01).No significant seasonal feature was noticed,but regional differences were found.The incidence rates were lower than 10/100 000 in 6 towns,while over 10/100 000 in other 19 towns.The hepatitis B incidence rate in male was higher than female (x2=-26.318,P<0.01) with a ratio of 2.63:1,and was the highest in adults aged 20-39 years with an incidence rate of 17.78/ 100 000.Most hepatitis B cases were farmers,accounting for 32.51%.Conclusions The incidence of hepatitis B among people of 15 years old or over in Yinzhou shows a decreasing trend year by year.It is necessary to intensify the prevention and control of hepatitis B infection,especially in male,young,civilian workers and farmers.The study of immunization strategy should be strengthened in key area and key population.
