Abstract:
Objective:To investigate the trend of hepatitis B incidence among children under 10 years in Zhejiang Province from 2004 to 2020 with age, period and birth cohort, so as to provide the basis for evaluating the implementation of hepatitis B prevention and control measures for children in Zhejiang Province.
Methods:Data of hepatitis B incidence among children under 10 years in Zhejiang Province from 2004 to 2020 were collected through the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. The trend in hepatitis B incidence was analyzed using an age-period-cohort model.
Results:The incidence of hepatitis B among children under 10 years in Zhejiang Province decreased from 12.91/105 in 2004 to 0.61/105 in 2020, with a reduction of 95.24%. The incidence showed an decreasing trend with the increase of age. Compared with 2012, the risk of hepatitis B incidence among children under 10 years appeared a tendency towards a decline with time, with the period rate ratio decreased from 4.546 (95%CI: 3.322-6.220) in 2004 to 0.277 (95%CI: 0.161-0.478) in 2020. Compared with the 2008 cohort, the risk of hepatitis B incidence appeared a tendency towards a decline with cohort, with the cohort rate ratio decreased from 25.535 (95%CI: 15.105-43.166) in 1995 to 0.135 (95%CI: 0.038-0.475) in 2020.
Conclusions:The incidence of hepatitis B among children aged under 10 years in Zhejiang Province from 2004 to 2020 showed a downward trend. The risk of hepatitis B incidence decreased with increasing age and advancing birth cohort.
