Abstract

OBJECTIVE: Examine the importance of occupational light-intensity physical activity (PA) and short bouts of moderate-vigorous PA (LSBPA), to opposing obesity, including an approximate replication of the London busmen study comparing waist circumference of workers with high versus low levels of occupational activity.

METHODS: Working adults wore an accelerometer, completed anthropometric measurements, and provided work schedules. Participants' (n = 435) activity was classified as either occupational or non-occupational minutes, and by intensity.

RESULTS: Body fat percentage was inversely associated with occupational-LSBPA in participants who did not meet PA guidelines, but not in those who met guidelines. In the London busmen replication, more active workers had smaller waist circumferences than sedentary workers, controlling for non-occupational activity.

CONCLUSIONS: Work-related LSBPA may be an important and under-recognized source of PA that opposes adiposity for people who do not meet PA guidelines.
