Children with asthma benefit from living near parks, nurse-led research finds
City-dwelling children with serious asthma may have fewer symptoms if they live close to green parks, nurse-led research suggests.
Experts in the United States found that the further away children lived from green spaces, the more days they experienced symptoms of asthma.
Researchers interviewed the parents of 196 children aged three to 12, all of whom had either visited emergency departments at least twice or been taken to hospital for their asthma over the previous year.
They calculated the number of days of asthma symptoms per child and worked out the distance between the child's home and the closest green space.
The results showed that children had one extra day when they suffered with asthma symptoms for every 305 metres between their home and a park.
Kelli DePriest, a public health nurse who led the study with colleagues at Johns Hopkins University School of Nursing and the University of Maryland School of Medicine in Baltimore in the US, said: 'The effect looks strongest for children aged six years and older.
'This might be because they have more freedom to choose where they want to go compared with younger children.
'These results are important because they provide further support for the benefits of city parks, and they suggest that the right building policies can improve children's health.'
She added: 'Living in a city environment increases the risk of childhood asthma, and factors associated with city living, such as air pollution, are also known to contribute to high rates of poorly controlled asthma.
'However, previous research has suggested that children with asthma can benefit from exercise. The presence of green spaces promotes physical activity and helps to lower pollution.'
Samantha Walker, director of research and policy at Asthma UK, said: 'This is an interesting study which suggests that living near green space encourages physical activity, decreases stress and filters environmental and air pollution.
'However, this is only a small study and further research with more participants is needed to see if this holds true in different populations in different parts of the world.
'One in 11 children in the UK have asthma – that's around three in every classroom – and we know that air pollution has a severe impact on the health and the quality of life of people with asthma.'
The study will be presented at the European Respiratory Society International Congress in Milan on 11 September.
