Individual, social, and physical environmental factors related to changes in walking and cycling for transport among older adults: A longitudinal study

To date, no longitudinal studies examined the change in walking and cycling for transport as distinct outcomes over time and investigated the predictors of those changes. Therefore, this present study examined the change in odds of engagement in walking and cycling for transport as distinct outcomes among Belgian older adults over a three-year follow-up period, and examined factors (i.e. socio-demographics, psychosocial, perceived social and physical environmental characteristics) related to these changes in engaging in walking and cycling for transport. Against our expectations, we found significantly higher odds of engaging in cycling for transport among older adults at follow-up compared to baseline and no significant differences in the odds of engaging in walking for transport. Interventions should assist older adults to increase their self-efficacy towards PA, their perceived benefits of PA, and their perception of land use mix diversity in their neighborhood in order to increase the engagement in walking/cycling for transport over time, or help to decrease their perceived barriers towards PA or their perception to have a lot of physical barriers to walk/cycle in their neighborhood. Future longitudinal studies with larger samples are warranted investigating interaction effects between different predictors at various levels to find out which factors can be further integrated into active transport interventions in older adults.
