Study Design: Longitudinal cohort study
Healthy AGeing in Scotland (HAGIS)
HAGIS is Scotland’s first comprehensive longitudinal study of people aged 50+, designed to understand older adults’ health, economic, and social circumstances and to inform policies that improve wellbeing. It belongs to the Health & Retirement Study (HRS) family and is intended to re‑interview participants every two years to enable within‑Scotland tracking and cross‑country comparisons via the Gateway to Global Aging.
