To analyze the trends in the prevalence and disease burden of enteric infectious diseases among the population under 20 years old in China from 1990 to 2021, to identify the severity and key affected populations, and to provide a reference basis for formulating prevention and intervention policies.
Data were sourced from the Global Burden of Disease Study (GBD) 2021 database. The Joinpoint regression model was used to analyze the temporal trends in the incidence, mortality, and disability-adjusted life years (DALYs) rates of enteric infectious diseases among the population under 20 in China from 1990 to 2021. The age-period-cohort analysis method was employed to assess the effects of age, period, and birth cohort on the trends in the disease burden.
The incidence rate of enteric infectious diseases in the population under 20 in China decreased from 48 373.02 per 100 000 in 1990 to 8 811.07 per 100 000 in 2021. The mortality rate decreased from 17.55 per 100 000 in 1990 to 0.43 per 100 000 in 2021. The DALYs rate decreased from 1 643.60 per 100 000 in 1990 to 52.31 per 100 000 in 2021. Joinpoint regression analysis showed that from 1990 to 2021, the incidence rate decreased by an average of 5.34% annually (AAPC=-5.34%, 95% CI: -5.50% to -5.18%), the mortality rate decreased by an average of 11.34% annually (AAPC=-11.34%, 95% CI: -11.71% to -10.97%), and the DALYs rate decreased by an average of 10.56% annually (AAPC=-10.56%, 95% CI: -11.03% to -10.10%). Age-period-cohort model analysis revealed that the 0-4 age group had a higher disease burden, significantly exceeding other age groups. With the progression of time periods, the risks of incidence, mortality, and DALYs for enteric infectious diseases in the population under 20 continued to decline. Compared to earlier birth cohorts, later birth cohorts had lower risks of incidence, mortality, and DALYs.
From 1990 to 2021, the incidence, mortality, and DALYs rates of enteric infectious diseases among the population under 20 years old in China showed a significant downward trend. However, for enteric infectious diseases children under 5 remain the key population, and comprehensive prevention and control measures should be implemented to further reduce the disease burden for this age group.
