What is the point of the latest follow up?
It is more than 15 years since we started recruiting the cohort and we recognise that there have been some changes in the size and lifestyles of the people in the SEATON cohort since the ten year follow up. We aim to use the same questions, breathing and allergy tests in the 15 year olds as we used at 5 and 10 years of age.
Our aims during this follow up study are:
- To see if exposure to Vitamins D and E since birth are still associated with increased risk of wheeze and reduced lung function at 15 years of age.
- To see if shorter fetal measurements will still be associated with increased risk of asthma at 15 years of age.
What is involved in the latest follow up?
Our latest follow up is very similar to the previous times you have visited us at 5 and 10 years of age.
We would like you to initially fill out two questionnaires, one for asthma and allergy and a second dietary questionnaire.
If you would be willing we would then like you to visit us in the Royal Aberdeen Children's Hospital and let us check the following;
- Spirometry - This measures the amount (volume) and speed (flow) of air that can be inhaled and exhaled by your lungs. We do this by getting you to blow into a handheld tube connected to a computer.
- Nitric Oxide Measurement - This measures the amount of Nitric oxide in your exhaled breath. We all breathe this out but people with asthma have higher levels of this. This is done the same way as Spirometry.
- Allergy testing - We would like to see if allergic to grass, cat, eggs or dust mites. This involves dropping a small amount of liquid containing these allergens onto your arm and giving your arm a slight scratch to see if any redness or itching happens.
- Bloods - We are taking bloods to test for certain proteins, vitamins, DNA and other molecules which might be related to asthma.
- Height, weight, waist and hip circumference are taken to see if there is any link for these too.
