Background: The current physical activity (PA) and health-related quality of life (HRQoL) literature warrants further investigation with general population samples. The exploratory-focused purpose of this study was to compare total PA-HRQoL and walking-HRQoL relations, include a measure of general happiness, and to evaluate potential activity-HRQoL demographic moderators.
Methods: A random sample of 351 adults completed an adapted Godin Leisure Time Questionnaire, the SF-36, and the Satisfaction with Life Scale.
Results: Partial correlations revealed small-to-moderate associations between walking/total PA and general health, vitality, and social functioning after controlling for key demographics (P < 0.05). A dependent t-test determined walking and PA as equally related to vitality and social functioning. Multiple regression revealed annual income as a moderator of the total PA/walking-social functioning relationship [F(3,315) = 9.71 and F(3,316) = 12.03, P < 0.01, respectively].
Conclusions: HRQoL may be considered with walking interventions and annual income. The contribution of PA to overall happiness appears to be minor.
