Abstract: In 2017, Livingstone et al. reported in the Lancet Commission Report that among the modifiable risk factors for dementia, hearing loss in midlife and later years had the greatest potential contribution to dementia prevention.The estimated contribution of hearing loss has changed from 9％ in the 2017 report to 8％ in the 2020 report and 7％ in the 2024 report; however, it remains the most significant factor.Following these reports and the World Health Assembly resolution on prevention of deafness and hearing loss, global efforts to promote appropriate diagnosis and intervention for hearing loss have intensified.In Japan, awareness campaigns for the general public, collaborative projects with physicians including other medical fields and speech-language therapysts, and advocacy efforts targeting the government have also become more active.Since the prevalence of risk factors for dementia, including hearing loss, varies significantly across countries, their respective contributions to dementia onset are also expected to differ.Therefore, calculating the contribution of hearing loss in each country is essential for policymaking and public health initiatives.In this study, we investigated the contribution of hearing loss to dementia incidence in Japan through a collaborative research project with the Danish Dementia Research Centre at the University of Copenhagen and the Kingdom of Denmark.
