Singapore is an ageing society. Its population of older adults, aged 60 years and older, will continue to increase in the coming decades. The Ministry of Health (MOH), Singapore has funded the Centre for Ageing Research and Education (CARE) at Duke-NUS Medical School to conduct THE SIGNS Study, a nationally-representative, longitudinal study (i.e., survey and follow-up the same set of individuals over time) of older Singaporeans. THE SIGNS Study is collecting comprehensive data on the health and wellbeing of older Singaporeans and the change in these over time.
Information collected in THE SIGNS Study includes indicators of physical and mental health and wellbeing, social engagement and participation, employment, intergenerational relationships, quality of life, and the impact of COVID-19. These national data contribute to the formulation, development, and refinement of policies and the planning of services for older adults in Singapore.
Till date, CARE has completed three waves of data collection in THE SIGNS Study. The first wave (THE SIGNS Study – Wave 1) was conducted in 2016-2017 with 4,549 older adults, of which 2,887 were followed up in the second wave (THE SIGNS Study – Wave 2) in 2019.
THE SIGNS Study – Wave 3 consist of Wave 3a (2023-2024), which followed up with 1,535 older adults from Wave 2, as well as a refreshed cohort of 5,306 older adults in Wave 3b (2024-2025).
As of 31 Dec 2025, 6,841 participants have been recruited for THE SIGNS Study – Wave 3. These participants will be followed up in Wave 4 starting 2027.
