Abstract:

Objective

To investigate the epidemic characteristics of hepatitis B in Hainan Province from 2010 to 2020, and to assess the application value of a seasonal autoregressive integrated moving average (SARIMA) model in predicting the trend of hepatitis B incidence.

Methods

Data on hepatitis B case reports in Hainan Province from January 2010 to December 2020 were collected. After performing seasonal decomposition, a SARIMA model was established to predict the trend of hepatitis B incidence from 2021 to 2030.

Results

The overall incidence of hepatitis B showed an upward trend from 2010 to 2020, with March to May and July to August being the peak periods of each year and February being the trough period. According to the prediction by the SARIMA model, the overall incidence of hepatitis B will decrease from 2021 to 2030, with 10991 (95% confidence interval: 208~68500) new cases of hepatitis B in 2030.

Conclusion

The overall incidence of hepatitis B in Hainan Province is decreasing, and the SARIMA model has high application value in predicting the trend of hepatitis B incidence.

Key words: Hepatitis B, Time series, SARIMA model, Prediction
