A multicentre randomised interventional prevention trial to develop and evaluate a flexible intervention to promote physical activity within worksites
The aim of the project was to develop and evaluate a flexible and problem-based intervention to promote physical activity within the workplace that requires no previous experience and could be implemented in any organisation. The intervention targeted mainly employees in low physical activity occupations and produced in an easy-to-implement tool-kit format. The intervention was evaluated in a quasi-experimental design involving 44 worksites across five large organisations. Half the worksites were randomly allocated to the intervention condition (being exposed to the whole intervention) and the remainder were allocated to the control group (who received the awareness component of the intervention only).

Topic: Generic Health Relevance and Cross Cutting Themes; Subtopic: Generic Health Relevance (all Subtopics); Disease: Public Health Research
Awareness, Motivation and Environment (AME):
Using leaflets, self-monitoring tools and team challenges, and thus focused on making changes at the individual level (awareness and motivation) but also encouraged changes in individuals' workplaces (environment) such as providing resources to encourage physical activity, posters to cue people to engage in physical activity and managers who support time spent in physical activity.
The control group received a short lifestyle advice leaflet, covering eating, physical activity, smoking, when they attended for their healthcheck etc.
Participants in the intervention group received a three month intervention delivered via a worksite facilitator and were followed up immediately post-intervention, as well as 3 months and 9 months after the intervention ended.
Primary outcome measures
International Physical Activity Questionnaire, measured at baseline, immediately post-intervention (3 months), 6 months post-intervention and 9 months post-intervention.
Secondary outcome measures
1. Body mass index (BMI)
2. % body fat
3. Resting heart rate
4. Diastolic and systolic blood pressure
Measured at baseline and again 12 months later.
