Breathing for Life
We know that a family history of asthma is an important reason why some children develop asthma. This research will investigate whether events which happen in pregnancy or early life contribute to the development of asthma in children whose mothers have asthma. Mothers who enrolled in the Breathing for Life Trial, a ransomised trial of fractional exhaled nitric oxide based management of asthma during pregnancy, are offered the opportunity to enrol their babies onto the follow-up infant study that looks at perinatal outcome and infant and childhood respiratory health. All babies born to mothers who participated in the Breathing for Life Trial during their pregnancy are able to participate.
