Manchester Asthma and Allergy Study (MAAS) age 25 plus follow up

The Manchester Asthma and Allergy Study (MAAS) is inviting adults, who were part of their original childhood study, to take part again. If you were born between 1995 and 1996 and were in the first MAAS study, researchers want to understand why asthma can carry on into adulthood for some people. This important follow-up involves a single, two-hour visit where you'll complete questionnaires and have some simple tests. While there are no direct health benefits to you personally, your input could greatly improve future understanding and treatments for asthma. This study helps doctors learn more about this common condition.

Asthma and allergic diseases

What is this study about?

You might already know that asthma is a common long-term health condition that affects many children. Even though we know a lot, doctors are still trying to understand exactly why it happens and why, for some people, it continues when they become adults. We know that things like your family's health history, as well as everyday things like pollution, allergies, and even colds, can play a part.

This study is a follow-up to a big research project called the Manchester Asthma and Allergy Study (MAAS). This project has been following children from the Manchester area since they were born in the mid-1990s. The team now wants to invite those same people, who are now adults aged 25 and over, to take part again. By checking in with them at this age, researchers hope to learn more about why asthma might continue for some people well into their adult lives.

The main goal of this research is to gather more information. This information is really important because it could help doctors and scientists better understand asthma. This better understanding might then lead to new and improved treatments for people with asthma in the future.

Key takeaways

This study is for adults who were part of the original MAAS childhood study.
It aims to understand why asthma continues into adulthood.
You'll have a single 2-hour visit, which can be at your home or the hospital.
The visit includes questionnaires, lung tests, and a blood test.
Your participation helps improve future asthma understanding and treatments.
You can stop taking part at any time without affecting your medical care.

Who may be eligible?

To take part in this study, you need to have been a participant in the original Manchester Asthma and Allergy Study (MAAS).

The first MAAS study recruited children from Wythenshawe and Stepping Hill Hospitals in 1995.

If you weren't part of that original MAAS study, unfortunately, you won't be able to join this follow-up.

Could this study suit you?

Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.

Were you born in the mid-1990s (roughly between 1995 and 1996)?
Did you take part in the original Manchester Asthma and Allergy Study (MAAS)?
Were you recruited for MAAS from Wythenshawe or Stepping Hill Hospitals?
Are you currently aged 24 to 34 years old?

Answer every question to see your result.

What does participation involve?

If you decide to take part, you'll have one visit that will last about 2 hours. You can choose where this visit happens – either at Wythenshawe Hospital, in the comfort of your own home, or you can even complete some parts online or by post if that's easier for you.

During this visit, you'll be asked to fill in some questionnaires. You'll also have some simple tests, including looking at how well your lungs work and having some blood taken. There are no medications involved in this study.

Potential risks and benefits

There won't be any direct health benefits for you personally by taking part in this study. However, the information you provide is very valuable. It will help researchers learn more about asthma, which could lead to better ways to understand and treat the condition in the future. The risks of taking part are very small. They are similar to what you might experience during routine medical tests, such as a little discomfort when a blood sample is taken. Remember, you can decide to stop taking part in the study at any time, for any reason, without it affecting your medical care.
