About this study

Official title: Ageing BIOmarker Study in Singaporeans (ABIOS)

The Ageing BIOmarker Study in Singaporeans (ABIOS) aims to understand the biological aging processes and how they affect health among people in Singapore. As people grow older, their risk of developing chronic diseases increases. This study aims to better understand the biological changes that come with age, particularly in three major ethnic groups: Chinese, Malay, and Indian adults over 21 years old. By examining a range of health indicators such as DNA methylation, inflammation, metabolism, cardiovascular health, physical function, and physical activity (i.e., molecular, physiological, and digital biomarkers of ageing), the study seeks to identify how ethnicity, lifestyle, and socioeconomic factors influence ageing. This unique study focuses on an all-Asian population, aiming to enhance our understanding of healthy aging across different ethnic groups.

Read the detailed description

Biological ageing is the primary driver of age-associated chronic diseases in older adults. Asian populations have been underrepresented in studies developing biological age predictors and understanding age-related diseases. Thus, the Ageing BIOmarker Study in Singaporeans (ABIOS) aims to characterise the biomarkers of ageing in Singaporeans, exploring associations between molecular, physiological, and digital biomarkers of ageing.

This is a single-centre, cross-sectional study that recruits healthy community-dwelling adults (≥ 21 years) from three different ethnic groups (Chinese, Malay, and Indian). Molecular biomarkers of ageing include a multi-omics approach, such as DNA methylation and metabolic and inflammatory parameters in blood, saliva, and stool. Physiological biomarkers of ageing include bone density, body composition, skin autofluorescence, arterial stiffness, physical performance (e.g., muscle strength and flexibility), cognition, and nutritional status. Digital biomarkers of ageing include three-dimensional facial morphology and objective physical activity. Additional factors such as habitual physical activity, dietary patterns, and medical history are also examined. The associations between the molecular, physiological, and digital phenotypes will be explored.

By examining diverse age-related biomarkers, clinical indicators, and lifestyle factors, ABIOS will offer unique insights into the ageing process within these ethnic groups to develop health policies and interventions for promoting healthy ageing in an all-Asian population.

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy Aging and Biological Aging, run by National University of Singapore at 1 site in Singapore.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 1 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

blood DNA methylation (time frame: Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jun 2026.
