RESUMEN
UNLABELLED: In Sweden, a work-site wellness programme implies reimbursing some of the expenses for health-promoting activities. Although work-site wellness programmes are readily available in Sweden, a large number of employees elect not to participate. OBJECTIVES: The aim of this study was to investigate the association of physical activity, self-reported general health assessment and self-efficacy with participation in a work-site wellness programme. STUDY DESIGN: A cross-sectional study design was used. METHODS: An online questionnaire was distributed to employees of a manufacturing company with 2500 employees in southwest Sweden. RESULTS: Those who took advantage of the work-site wellness programme assessed their general health as better and had higher assessment of physical activity. The study showed that being enlisted also implies a higher level of physical activity and general health; however, the effect sizes of these correlations were small. Self-efficacy, i.e. perceived behavioural control, was not associated with participation in the work-site wellness programme. However, self-efficacy was correlated with both general health assessment and physical activity. A regression analysis to determine explanatory contributions to the general health assessment score showed no significant contribution from participation in a work-site wellness programme, but was instead explained by perceived behavioural control and physical activity. CONCLUSIONS: Given the small effect size of the difference in physical activity between participators and non-participators in the work-site wellness programme, it is probable that only a small proportion of participators changed their health-promoting activities as a result of the work-site wellness programme.
