Incidence of dementia among individuals 70 years and older in Norway: A HUNT study.

ABSTRACT: BackgroundWith increasing population longevity, Alzheimer's disease and dementia have become a health priority, and high-quality incidence estimates are needed.ObjectiveTo provide reliable and precise incidence estimates of dementia applying a population-based sample of individuals aged 70+.MethodsA longitudinal cohort design was used, with baseline assessment in the Norwegian HUNT4 70+ study (2017-19) and at follow-up four years later (2021-23). Age-specific dementia incidence rates, standardized for the Norwegian population, were calculated as the number of new dementia cases per 1000 person-years assuming onset midway between study waves with inverse probability weights based on baseline factors associated with non-participation or death.ResultsAmong 5229 dementia-free individuals at ba
