[Commute mode - physical activity and the possibility of change to active commuting among Japanese workers: a descriptive study by region].

ABSTRACT

OBJECTIVES: Changing the mode of commuting from nonactive by car or motorcycle to active by walking, cycling, or public transport is expected to benefit health. However, the proportion of nonactive commuters who can change their commute mode to active forms remains unclear. The aim of this study was to determine the proportions of nonactive commuters and of those who can change their commute mode to an active form in various regions in Japan. METHODS: In this descriptive study, data were used from an online survey conducted from April to May 2021. Participants included 3,000 adults (20 to 79 years), who were registered with an online survey company. Workers were asked their means of transportation to work and commuting time. Workers using a car or motorcycle for more than 1 minute for commuting were defined as nonactive commuters, and the others were defined as active commuters. Then, nonactive commuters were asked about the possibility of changing their commute mode to active commuting (0%-100%, 11 options in 10% increments). The possibility of change was classified into four groups, i.e., impossible (0%), difficult (10%-40%), probably possible (50%-90%), and possible (100%). The proportions of nonactive commuters and nonactive commuters who can transition to active commuting were described by region. RESULTS: A total of 2,683 participants answered the survey, including 1,647 workers, of whom 1,551 were commuters. The nonactive commuters accounted for 41.4% of commuters overall. The proportion of nonactive commuters was higher in rural than in urban regions. The proportion of nonactive commuters who could change their commute mode was 32.9% of the nonactive commuters or 12.8% of all workers. Among the nonactive commuters, the proportion who could change their commute mode was higher in urban than in rural regions. Of the total workers, the proportion of nonactive commuters who could change their commute mode was higher in rural regions. CONCLUSION: Nonactive commuters accounted for 41.4% of all commuters. The proportion of nonactive commuters who could change their commute mode among nonactive commuters was higher in urban regions. However, in rural regions, as the proportion of nonactive commuters was high, the proportion of nonactive commuters who could change their commute mode among total workers was also high. These results suggest that some of nonactive commuters can change their commute mode from nonactive to active commuting, in rural as well as in urban regions.
