Influence of psychosocial work environment on adherence to workplace exercise.

Objective: Physical exercise can reduce the prevalence of musculoskeletal disorders, but adherence to exercise is challenging for many employees. This study determines prognostic factors for adherence to workplace exercise.

Methods: In Copenhagen, 132 office workers with neck/shoulder pain were randomized to 2 or 12 minutes of exercise five days a week. Low, medium, and high adherence was defined as performing less than 10, 10-30, or more than 30 exercise sessions during the subsequent 10 weeks. Odds ratios (OR) for adherence were modeled by logistic regression.

Results: Lower adherence to the 10-week exercise program was predicted by poorer psychosocial work environment and lower exercise self-efficacy. A longer exercise program was not associated with lower adherence.

Conclusions: Concurrent strategies to improve psychosocial work environment and individual exercise beliefs should be considered when implementing exercise at the workplace.
