The impact of a free older persons' bus pass on active travel and regular walking in England.

Abstract

We assessed the potential public health benefit of the National Bus Pass, introduced in 2006, which permits free local bus travel for older adults (≥ 60 years) in England. We performed regression analyses with annual data from the 2005-2008 National Travel Survey. Models assessed associations between being a bus pass holder and active travel (walking, cycling, and use of public transport), use of buses, and walking 3 or more times per week. Having a free pass was significantly associated with greater active travel among both disadvantaged (adjusted odds ratio [AOR] = 4.06; 95% confidence interval [CI] = 3.35, 4.86; P < .001) and advantaged groups (AOR = 4.72; 95% CI = 3.99, 5.59; P < .001); greater bus use in both disadvantaged and advantaged groups (AOR = 7.03; 95% CI = 5.53, 8.94; P < .001 and AOR = 7.11; 95% CI = 5.65, 8.94; P < .001, respectively); and greater likelihood of walking more frequently in the whole cohort (AOR = 1.15; 95% CI = 1.07, 1.12; P < .001). Public subsidies enabling free bus travel for older persons may confer significant population health benefits through increased incidental physical activity.
