| アブストラクト | OBJECTIVE: This study aimed to clarify the seasonality of the incidence of sudden sensorineural hearing loss and the impact of the coronavirus disease 2019 pandemic. STUDY DESIGN: An interrupted time-series design. SETTING: Comprehensive insurance claims data from the National Database of Health Insurance Claims and Specific Health Checkups of Japan collected between October 2013 and September 2023 were used. METHODS: Individuals who developed sudden sensorineural hearing loss were identified as those with disease code(s) and drug code(s) for steroids with a prior disease-free period of 1 year. Time series data on incidence rate were created from the number of the incidence and population for each month. An interrupted time series analysis with a seasonal autoregressive integrated moving average model was performed. RESULTS: According to the model with the lowest Akaike's information criterion, the incidence of sudden sensorineural hearing loss was seasonal: more frequent in early summer and less frequent in winter. The interrupted time-series analysis revealed a significant decrease of 1.38 cases per 100,000 people (95% confidence interval: 1.01, 1.76) each month during the pandemic and a significant temporary additional decrease of 2.07 cases per 100,000 people (95% confidence interval: 1.44, 2.70) in April and May 2020. CONCLUSION: This population-based study in Japan reveals seasonality in the incidence of sudden sensorineural hearing loss and a decrease during the coronavirus disease 2019 pandemic. Despite the observational nature of the study, the findings may be useful in elucidating the etiology of sudden sensorineural hearing loss. |
