Share and Print

1. Purpose of the Study

Your child/ward has been invited to participate in the Youth Health Survey (YHS) conducted by the Health Promotion Board (HPB) among selected Ministry of Education mainstream schools (Secondary Schools, Junior Colleges and the Centralised Institute) in Singapore.

The aim of the study is to find out more about the health of youth in Singapore. The information collected will be used to plan and evaluate health policies, health programmes and services.

The study aims to recruit 5,000 participants across 4 mainstream schools in Singapore in early 2020 over a period of 1 year.

As your child/ward is under 21 years old, parental consent is required for him/her to participate in this study. Please read the information provided in this information page and if you allow your child/ward to take part in this study, do provide your consent with the given link available at the bottom of this page.

Following your consent for your child’s/ward’s participation in the study, the study procedures will be explained to your child/ward and his/her consent for participation will also be sought.

2. Procedures Followed in the Study  

The study will comprise 2 components; the health survey, and the health screening.

Health Survey

Students participating in the study will complete the survey in school in a single session, in either the school computer lab or a designated room, using the school computers, tablets, or their personal devices. The survey will cover topics pertaining to health behaviours (including but not limited to physical activity, nutrition, smoking and alcohol use) and will take about 30 minutes to complete.

Health Screening

Students participating in the health screening will need to fast for at least 8 hours prior to the health screening and will be allowed to drink water. Reminders will be sent to you and your child to ensure that your child is prepared for the health screening session. 

On the day of the health screening for your child/ward, a trained staff will conduct the following in school:

  1. Measurement of height, weight, waist and hip circumference;
  2. Measurement of blood pressure;
  3. Collection of a sample of about 15ml (or 1 tablespoon) of blood to test for diabetes and cholesterol;
  4. Collection of a sample of urine for urinary cotinine, creatinine and sodium tests.

The health screening will take about 20 minutes and upon completion, your child/ward will be provided refreshments.

Storage of Remaining Blood Sample
You will be asked if you agree for any of your child’s/ward’s remaining blood sample to be stored for future HPB approved health studies. Any future studies that use your child’s/ward’s blood will also need approval from an Institutional Review Board (IRB) to ensure that the health studies are ethical and scientifically sound. 

Follow-up Studies
You will be asked for permission to be contacted in the future for your child’s/ward’s participation in future studies that your child may be suitable for. If your child is deemed suitable for a future study, HPB will contact you to inform you about the study, and for you to consider allowing your child/ward to participate in it.

Data linkage
You will be asked if you agree to link your child’s/ward’s data collected to other databases to allow us to better understand the health of Singapore residents, including trends over time. If you agree, the following information may be linked with other databases:
         • Personal information (Name and NRIC number)
         • Data collected in YHS (Health Survey and/or Health Screening)
After the data linkage, the database used for analysis will not contain personal identifiers and will be stored for as long as the purpose of the analysis remains relevant. 

3.Possible Risks and Side Effects

If your child/ward feels uncomfortable answering any of the questions, he/she may choose to skip these questions.

Obtaining blood can cause pain, bleeding, bruising, or swelling at the site of the needle stick. Fainting sometimes occurs and infection rarely occurs. Trained medical staff will be onsite to attend to any medical needs of participants undergoing screening.

4. Possible Benefits from Participating in the Study

Your child’s/ward’s participation in the YHS will help to improve the health of Singapore’s youth by enabling us to better plan and evaluate national health programmes. Past study results have been used to plan and improve health programmes and services tailored for Singapore’s youth.

Your child will receive a health screening report with a copy of the results of his/her health screening within six weeks of completion. The results include:

  1. Height, weight and body mass index
  2. Blood pressure
  3. Blood sugar and cholesterol level

5. Important Information for Female Participants

The YHS is not expected to pose any additional risks to female participants who are pregnant other than those ordinarily encountered in daily life. Therefore, participants who are pregnant are eligible to participate in the survey. However, they will not be eligible to participate in the health screening component of the study. 

6. Costs & Payments of Participating in the Study

Upon completion of the health survey, your child will be eligible for a $10 token of appreciation. This token of appreciation will be given to the child upon successful completion of the survey.

No payment is needed for your child/ward to participate in the health screening. HPB will be absorbing the cost of the screenings (worth approximately $80 per child).

7. Voluntary Participation

Your child’s/ward’s participation in this study is voluntary. He/she may stop participating in this study at any time. You may ask for your child’s/ward’s data to be removed from the YHS database for future analysis, withdraw your child’s/ward’s participation to the follow-up surveys or your consent to data linkage at any time, or request for your child’s/ward’s biological samples to be discarded or destroyed by writing to the Principal Investigator without needing to give reasons.

In the event of any new information becoming available that may be relevant to your child’s/ward’s willingness to continue in this study, you will be informed in a timely manner by the Principal Investigator or his/her representative.

Do note that the study procedures are conducted solely for the purposes of research and is not part of your child’s school assessment, and his/her participation will have no bearing on his/her standing in school.
