Study for Teens 13 to 17 Years Old Who Have Asthma

Why are we doing this research?

Cincinnati Children’s is conducting a research study, sometimes known as a clinical trial or clinical study, to look at the respiratory health effects of exposure to ultrafine particles, a form of air pollution.

Who can participate?

Teenagers 13 to 17 years old who have been diagnosed with asthma and who do not smoke cigarettes may be eligible to participate.


  • Asthma
  • Chest and Lungs - Respiratory Tract

What will happen in the study?

This study will last for about one year and include 4 study visits. Here are some of the things that will happen in this study:

Teens will be asked to wear a personal ultrafine particle (PUFP) sensor on a backpack or on their belt on two different occasions. Each time, participants will wear the sensor for about three hours every day for one week (7 days).

Participants will also be asked to:

  • Have blood draws
  • Perform breathing tests
  • Wear a Fitbit to measure sleeping patterns, activity level, and heart rate
  • Complete questionnaires about stress, sleep, etc.
  • Complete study questionnaires on a study-assigned smartphone

Parents and teens will be given a consent form that thoroughly explains all of the details of the study. We will review the consent form with you and your child and be sure that all of your questions are answered.

What are the good things that can happen from this research?

Participants will not receive a direct benefit from being in this study. However, the information we learn from this study may benefit other teenagers in the future.

What are the bad things that can happen from this research?

Possible risks and discomforts will be discussed with parents or guardians interested in learning more about the study.

Will you/your child be paid to be in this research study?

Participants may receive up to $320 for time and effort.
