Abstract
White-collar workers spent 6.4 hours in sedentary behavior (SB) during work hours, significantly more than the 4.8 hours spent by blue-collar workers.
- White-collar workers engaged in SB for 73% of their work time, while blue-collar workers spent 55% of their work time in SB.
- In contrast, blue-collar workers participated in light-intensity physical activity (LPA) for 3.5 hours, compared to 1.9 hours for white-collar workers.
- Prolonged sedentary bouts (≥30 minutes) were more common among white-collar workers.
- During leisure time, both groups showed similar levels of SB, LPA, and moderate-to-vigorous physical activity (MVPA).
