People who walk, cycle and travel by train to work are at reduced risk of early death or illness compared with those who commute by car, according to a study by Imperial College London and the University of Cambridge.
Findings of the study of over 300,000 commuters in England and Wales suggest increased walking and cycling post-lockdown may reduce deaths from heart disease and cancer.
The study, funded by the National Institute for Health Research School for Public Health Research, and published in The Lancet Planetary Health, used Census data to track the same people for up to 25 years, between 1991-2016.
It found that, compared with those who drove, those who cycled to work had a 20% reduced rate of early death, a 24% reduced rate of death from cardiovascular disease, a 16% reduced rate of death from cancer, and an 11% reduced rate of a cancer diagnosis.
Furthermore, walking to work was associated with a 7% reduced rate in cancer diagnosis, compared to driving.
However, associations between walking and other outcomes, such as rates of death from cancer and heart disease, were less certain.
According to the team behind the study, one potential reason for this is people who walk to work are, on average, in less affluent occupations than people who drive to work, and more likely to have underlying health conditions, which could not be fully accounted for.
The paper also revealed that compared with those who drove to work, rail commuters had a 10% reduced rate of early death, a 20% reduced rate of death from cardiovascular disease, and a 12% reduced rate of cancer diagnosis.
This is likely due to them walking or cycling to transit points, although rail commuters also tend to be more affluent and less likely to have other underlying conditions, said the team.
Dr Richard Patterson from the MRC Epidemiology Unit at the University of Cambridge, who led the research, said: “As large numbers of people begin to return to work as the Covid-19 lockdown eases, it is a good time for everyone to rethink their transport choices.
“With severe and prolonged limits in public transport capacity likely, switching to private car use would be disastrous for our health and the environment.
“Encouraging more people to walk and cycle will help limit the longer-term consequences of the pandemic.”
The study also assessed whether the benefits of each mode of travel differed between occupational groups and found that potential health benefits were similar across these groups.
The team used data from the UK Office for National Statistics Longitudinal Study of England and Wales, a dataset that links data from several sources including the Census of England and Wales, and registrations of death and cancer diagnoses.
The data revealed overall 66% of people drove to work, 19% used public transport, 12% walked, and 3% cycled.
Men were more likely than women to drive or cycle to work, but were less likely to use public transport or walk.
Dr Anthony Laverty, senior author from the School of Public Health at Imperial College London, said: “While not everyone is able to walk or cycle to work, the government can support people to ensure that beneficial shifts in travel behaviour are sustained in the longer term.
“Additional benefits include better air quality which has improved during lockdown and reduced carbon emissions which is crucial to address the climate emergency.”
