As the Northern Finland Birth Cohort 1966 enters its seventh decade, researchers are turning to digital tools to unlock secrets of healthy aging.
The study, established in 1965–1966, tracks over 9,800 individuals from pre-birth through adulthood, making it one of the longest-running birth cohorts globally. A new follow-up launched in 2026 as participants reach 60 years old integrates hip-worn activity trackers, Oura rings, mobile apps, and 24/7 physiological measurements to monitor health continuously.
Professor Sylvain Sebert said:

Finland’s homogeneous population and comprehensive health registers enable precise tracking of health and social outcomes over time. The study aims to inform prevention strategies, healthcare planning, and policy for aging populations, particularly addressing multi-morbidity and sustainable healthcare systems.
