CHILL is a research study, which aims to find out whether reducing air pollution from traffic is good for children’s health. We are particularly interested in whether interventions to reduce air pollution improve the growth of children’s lungs. We are also interested in children’s respiratory symptoms (like wheezing, sneezing, coughing), whether they have had to miss school for chest problems, and what impact this may have had on their parents. Finally, we are interested in children’s physical activity levels and how much air pollution they are exposed to.
To do this we plan to recruit Year 2, 3, and 4 children from primary schools in central London and Luton to take part because the local councils in these areas are trying to reduce air pollution. We aim to recruit 60 children from each school; over 3,000 children in total.
