Background and study aims
We know that early life is a key period for our development and exposures to environmental hazards such as ambient air pollution, environmental tobacco smoke, water and food contaminants, noise, pesticides and ultraviolet light may lead to long-term health effects with large social and economic costs. This means identifying and implementing cost-effective preventive actions and policies to reduce our exposures to adverse environmental hazards during this critical early-life period would have the greatest impact.
ATHLETE is studying the human exposome – the totality of all non-genetic exposures including all hazards in our external physical and chemical environments as well as our internal molecular signatures. This approach encompasses the complexity of how we experience our environment, therefore our exposures, and will help us understand what exposures we experience during pregnancy, childhood, and adolescence, as well as identifying and implementing interventions to reduce our exposure to the urban and chemical exposome.
Building on the previous work in HELIX, this study will build on 16 existing birth cohorts from 11 European countries to:
What does the study involve?
ATHLETE has two sub-studies:
Data collection from BiB participants
We followed-up BiB participants (n=233) who were previously involved in a study called HELIX, and collected a suite of new data. This data will be used to understand how our exposures impact on our health.
Citizen scientists and co-production of interventions
We recruited 10 children from 2 schools in Bradford, and 10 children from 2 schools in Barcelona, Spain, to take part as citizen scientists to understand where and when key exposures to urban pollutants on their school journey were occurring.
This sub-study will demonstrate the development and evaluation of co-produced effective and scalable interventions to reduce personal exposure to the harmful effects of the urban exposome. We focused on primary school-aged children as children are particularly vulnerable to their urban environment – a source of physical, chemical and behavioural exposures (e.g. pollution, lack of green space, noise, physical activity) – all of which have been associated with a variety of health outcomes including asthma, mental health, obesity and cognitive development).
Schools are often urban exposome ‘hotspots’ located in areas of high pollution or noise, which is compounded by high levels of car use during the ‘school run’. We know that within the UK around half of children are driven to school.
Pupil citizen scientists carried personal air pollution sensors to quantify their levels of exposure and identify where these exposures were occurring on their school journey. Static air pollution sensors were also placed in schools to monitor levels throughout the data collection period and questionnaires were completed to understand school travel modes and preferences, play and physical activity, and self-assessed physical and mental health. Citizen scientists also participated in ‘walkalong’ interviews with researchers to explore their perceptions of the urban exposome on their journey from school to home, as well as their perceived barriers and enablers to reducing these harmful exposures. These measures fed into co-production workshops at each school where children, parents, teachers, and local stakeholders worked together to come up with interventions to reduce the exposure children experience on their school journeys. These co-produced interventions were then implemented and we will follow-up with the children, parents, and schools using both quantitative and qualitative methods to understand the sustainability of these co-produced interventions.
