Background: Regular physical activity (PA) is associated with a reduced risk for chronic health conditions and improved health-related quality of life (HRQoL). Efforts to increase PA have included workplace health promotion. Currently, little is known about the effect of these programs on overall HRQoL. Aim: To evaluate whether participation in a pedometer-based PA program in the workplace was associated with changes in HRQoL. Methods: 487 voluntary employees enrolled in a health program completed the SF-12 Health Survey at baseline and 4 months. Change in Physical and Mental component summary scores (PCS; MCS) was assessed with multivariable regression analysis, adjusting for covariates. Results: Participation in the program was associated with an increase of 1.5 MCS units (95% CI: 0.76, –2.09). Greater improvements in MCS were observed in those reporting an increased level of PA during the program [1.9 (CI: 0.78, 2.92) versus 0.9 (CI: –0.12, 2.03)] and a lower baseline MCS score [6.3 (CI: 4.80, 7.62) versus –1.5 (CI: –2.21, –0.80)]. No change in PCS was observed. Conclusions: Participation in this workplace PA program was associated with improvements in the mental component of HRQoL. We recommend the use of a broad perspective of health be used in both the implementation and evaluation of workplace PA programs.
