Aim

To examine differences in non-occupational physical activity behaviour in workers who engage in high and low occupational physical activity.

Design

Cross-sectional survey of 112 otherwise comparable volunteers in active (56 walking postal delivery workers) or inactive (56 administrative postal workers) occupations in Glasgow (Scotland) in 2007.

Methods

Twenty four-hour physical activity (steps and time standing, walking and sedentary) patterns were measured using activPAL™ for seven days. Comparisons were made during 8-hour work-shifts, during non-work hours on work-days and during the 2 non-work days.

Results

Age and body mass index of delivery and office staff, respectively, were (means (SD)) 38 (9) years versus 40 (7) years and 26.3 (3) kg m^− 2 versus 27.4 (4) kg m^− 2. Delivery staff spent substantially longer time than office staff upright (6.0 (1.1) h versus 3.9 (1.5) h) and walking (3.1 (0.7) h versus 1.6 (0.7) h) and amassed more steps (16,035 (4264) versus 6709 (2808)) during 8-hour work-shifts and over 24 h on work days. During non-work hours of work-days and during non-work days, there were no significant differences in physical activity between the groups. The results were unchanged when the 15 women were excluded.

Conclusion

Having a more active occupation is not associated with more inactivity during non-work hours.
