Children's Health in London and Luton (CHILL)

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 can improve children’s lung growth and respiratory symptoms, activity levels and brain function. We are also interested in whether exposure to air pollution in childhood leaves markers on genes that reflect pollution levels over time. We have recruited over 3,300 primary school pupils across London and Luton to take part from 44 London schools and 41 Luton schools. These children will be assessed once a year for up to four years.
