Occupational and sex differences in active commuting among Canadian workers from 2006 to 2016

Active commuting (AC) to and from work is associated with numerous health benefits, through increased physical activity. This study examined whether occupation types and part-time work, by sex, were associated with AC in a population-based sample of Canadian workers.

Cross-sectional public use microdata files from the 2006 (n=363,048), 2011 (n=370,672), and 2016 (n=362,310) Census of Population were examined. Multinomial logistic regression models were used to estimate the odds of cycling, walking, and using public transit, relative to using a private motorized vehicle, by occupation and sex. Time trends in mode share were also analyzed.

In 2016, commuting by private motorized vehicle and cycling were more common among males, while public transit and walking were more common among females. Occupations in art, culture, recreation, and sport were associated with the greatest odds of cycling (odds ratio [OR]=3.02, 99% confidence interval [CI]: 2.65 to 3.39), while those in trades, transportation, natural resources, and manufacturing had the lowest odds of cycling (OR=0.47, 99% CI: 0.44 to 0.51) and walking (OR=0.36, 99% CI: 0.33 to 0.38). Since 2006, relative declines of 1% and 8% in the proportion of workers commuting by driving and walking, respectively, were observed (absolute change of -1% each). Relative increases of 14% and 12% were observed for cycling and public transit, respectively (absolute changes of less than 1% and 1.5%, respectively).

This study found that sex and occupation are important correlates of AC among Canadian workers. Further research aimed at understanding occupational barriers and facilitators may inform future AC interventions.
