2025-12-01

Only households that have received an official invitation letter may participate in this survey

(1) Background
The Department of Health (DH) is conducting a territory-wide population health survey (PHS) to understand the health status of the Hong Kong population, their health-related lifestyle behaviour and practices, and to collect other important health information. The survey commences on 18 September 2025 and is expected to last for 15 months.

(2) Objectives
To strengthen the Government's information base to assess health status of the population of Hong Kong.

(3) Target population
Hong Kong residents aged 15 or above
(excluding inmates of institutions, persons living on board vessels, foreign domestic helpers and visitors)

(4) Contents of PHS
The PHS comprises two parts:

A. Household Survey
DH has commissioned the MOV Data Collection Center Limited to conduct the PHS 2025/26. A sample of quarters is selected by DH using a scientific method. Invitation letters will be sent to the selected quarters by post. Household representatives and household member(s) shall read “Personal Data Collection Statement” and “Terms & Conditions”.

Online questionnaire
Household representative can activate the online questionnaire system (via https://phs.portal.ehealth.gov.hk) using the household reference number and activation key printed on the invitation letter to complete online household questionnaire. The household reference number and activation key are unique to each selected quarter and is not transferrable.

After completion by the household representative, all eligible household members aged 15 or above can continue to complete the online individual questionnaire by logging into the online questionnaire system themselves. The individual questionnaire will ask about each respondent's physical and psychosocial health status, health behaviour and preventive health practices.

Household interview
If necessary, household representative and/or household member(s) can make an appointment by phone or via online platform to request for face-to-face interview. The interviewer will assist to complete both household questionnaire and individual questionnaire.

If the online questionnaire is not completed by the deadline as stated in the invitation letter, an interviewer from the MOV Data Collection Center Limited commissioned by the DH will visit the household to assist all eligible members aged 15 or above in the household to complete the online questionnaire. The interviewer will wear a vest uniform in teal colour with the “Population Health Survey” and the “Department of Health” logos. The interviewer will also carry an identity card issued by DH for identification purpose.

B. Health Examination
DH has commissioned the KingMed Diagnostics (Hong Kong) Limited to provide health examination service for PHS 2025/26. All respondents aged between 15 and 84 who completed the questionnaire will be invited to sign a consent form for health examination. Randomly selected respondents will be further invited to undergo health examination at the designated centers of the KingMed Diagnostics (Hong Kong) Limited located in Tsuen Wan, Mong Kok, Tsim Sha Tsui, Causeway Bay and Central. The health examination will take about 45-60 minutes and is free of charge. Free health examination reports and health advice will be provided as appropriate.

The health examination items include:

Physical measurements

blood pressure, body height and weight, waist and hip circumferences;

Biochemical tests

lipid profile (e.g. total cholesterol, LDL-cholesterol, HDL-cholesterol and triglyceride);
tests for glycated haemoglobin (HbA1c) and fasting plasma glucose;
tests for haemoglobin, iron status (e.g. serum ferritin and serum iron), inflammatory markers (e.g. C-reactive protein and alpha-1-acid glycoprotein);
tests for viral hepatitis B and C;
spot urine test for iodine; and
24-hour urine test for sodium, potassium and creatinine.

To follow-up on the health examination results, participants can choose to visit their family doctor or District Health Centre/Express (DHC/E) for subsequent care. For more information on DHC/Es, please visit www.dhc.gov.hk.

(5) Handling of data collected by PHS 2025/26

Let's Support

If your household is invited to take part in PHS 2025/26, please give us your generous support. Your active participation is crucial for improving public health in Hong Kong.

(6) Relevant information and publications:

(7) eHealth registration and sharing of data
Electronic Health System (eHealth) is a territory-wide, patient-oriented electronic sharing platform which enables authorised healthcare providing organisations in the public and private sectors to access and share participating patients' electronic health records for healthcare purposes. If respondents have not registered for eHealth, our interviewer can assist them to register during the household visit, to build a lifelong and comprehensive personal electronic health record, enable healthcare professionals to provide them with continuous healthcare services, and enable them to manage their own and their family members' health records through the eHealth App.

After completing the questionnaire, respondents can choose to deposit the health information collected through PHS 2025/26 into their “Personal Folder” in eHealth, enabling them to retain and utilise relevant health information. The DH will provide advice and referral letters to those with abnormal test results in the health examination. The test reports will also be deposited in their personal eHealth accounts, enabling them to seek appropriate follow ups and treatment from their family doctors or district health centres. For details, please visit www.ehealth.gov.hk.
