Evaluation of the Dynamic Work Intervention for Office Workers to Reduce Sedentary Behaviour

Evaluation of the Dynamic Work Intervention for Office Workers to Reduce Sedentary Behaviour

Long-term sitting has been associated with multiple health risks. To reduce sitting time for office workers in a Dutch insurance company, an intervention will be implemented. The goal of this study is to evaluate this intervention on the short term (3 months) and long-term (12 months).

Large volumes of sitting time have been associated with multiple health risks such as diabetes, heart disease and premature death. Especially, in office workers sitting time per day can accumulate to over 10 hours a day. To reduce sitting time for office workers in a Dutch insurance company, an intervention will be implemented. The intervention contains the introduction of alternative workstations, intervention sessions with an occupational physiotherapist and an activity tracker with a self-help program booklet. The goal of this study is to evaluate the (cost) effectiveness of this intervention on the short term (3 months) and long-term (12 months). The primary outcome is objectively assessed sitting time.

In a cluster randomized controlled trial 250 employees of an insurance company will participate in the study. After baseline measurements, matched departments will be randomly assigned to the control or intervention group. The evaluation includes an economic and process evaluation.

Inclusion Criteria:

• Employed by the insurance company for at least the duration of the study (12 months)
• Employed at least 28 hours per week
• Employed at one of the participating departments

Exclusion Criteria:

• Already access to the Dynamic Working Intervention
• Unable to stand or walk for longer time periods (i.e. wheelchair bound)
• Pregnancy
