High Blood Pressure – Adult Hypertension Onset in Youth (SHIP AHOY) Study

Condition or Therapy:

Hypertension (high blood pressure) 



What is the goal of this study?

We want to learn more about how high blood pressure in teens affects their risk for injury to their heart and blood vessels later in life. We want to learn how diet and exercise influences blood pressure.

Participants who take part in this study will get up to $125 gift card to thank them for their time.

Who can join the study?

This study might be a good fit if you think your child or teen might have high blood pressure. 

This study is for children and teens that:  

  • Might have high blood pressure
  • Are 11 to 18 years old
  • Are not taking medicine to control blood pressure, cholesterol, or type 1 or type 2 diabetes

What will happen if my child takes part in this study?

If your teen chooses to take part, they will go through a series of tests to learn how blood pressure has affected their body. This includes:

  1. A screening visit (1 hour long). At this visit we would:
    • Measure blood pressure while the teen is seated
  2. A study visit (4 hours long). At this visit we would:
    • Collect basic information about you and your teen, including medical and family history
    • Collect blood and urine samples 
    • Perform a pregnancy test, if teen is female
    • Record blood pressure from their last clinic visit and include as part of our research records
    • Measure blood pressure while the teen is seated
    • Take a picture of the teen’s heart using ultrasound (called an echocardiogram)
    • Test blood vessels by placing a pressure sensor the size and shape of a pencil (without using needles or radiation) on pulse points on the leg and neck. 
    • Ask the teen to fill out questionnaires about cognitive function, sleep habits, physical activity and diet  

We would also ask a parent to fill out study questionnaires.

At the end of the study visit, study staff will place a special blood pressure monitor that your teen would wear for 24 hours. You would return the monitor when the study is finished.
