A new study has looked at how different types of programs aimed at getting people to be more physically active while traveling can affect certain groups of people in the UK. The researchers found that these programs tend to work better for women and older adults, increasing their chances of walking or cycling instead of driving. However, they didn't find any evidence that these programs help or hurt people based on their age, ethnicity, or social status. This is good news, as it suggests that these types of programs can actually help reduce health inequalities, rather than making them worse.
