About this study
The aims of this interventional study are of two-fold. First, the study aims to develop the capacity to facilitate the collaborating NGOs to address the social determinants of aging well for 3-N seniors. The second aim of the study is to evaluate the impact of the transitional support for 3-N elders. The main question is aims to answer is:
Does the transitional support facilitate a better physical and psychological wellbeing in 3-N seniors.
Participants will be categorized into transitional-support group or non-transitional-support group based on their existing community service. They will join evaluation at four timepoints (baseline 3-, 6-, and 12-month) over the 1-year follow-up period.
Read the detailed description
The project will set up the following digital platform:
- Neighbor Link for Healthy Living
- Healthy Lifestyle Hubs without Walls
- Service Connect Compass Central to the concept of prompting 'aging well' through addressing the social determinants of health, the evaluation not only focuses on the direct impact on the social cohesion of the beneficiaries with their immediate community context, but also captures the indirect impact on the broader dimensions reflecting 'aging well'.
- Conditions
- 3-nil Buildings Seniors

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Mapped intervention based on health statusBehavioural
Intervention will be conducted to improve lifestyle based on their needs which include 1) Neighbor Link for Healthy Living, 2) Healthy Lifestyle Hubs without Walls and 3) Service Connect Compass.

Questions about this trial
What is this clinical trial studying?
A study testing Mapped intervention based on health status in people with 3-nil Buildings Seniors, run by The University of Hong Kong at 1 site in Hong Kong.
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 3 inclusion and 3 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: opening soon, as of the sponsor's last update on 5 Nov 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 Hong Kong. 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?
Contact Doris Sau Fung YU, PhD (852-3917-6319, dyu1@hku.hk), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Edmonton Frailty Scale (time frame: Changes from baseline to 3 month, 6 month, 12 month post-intervention.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07920328, which also lists 19 linked publications.
