Brief Summary

The primary aim of this study is to assess the feasibility of an intervention to reduce and break up prolonged sitting time in full-time police staff. The secondary aims of this study are to assess preliminary effects on patterns of sedentary behaviour (number of breaks, number of prolonged sitting bouts, average duration of prolonged sitting bouts, and total prolonged sitting duration), additional measures of sedentary behaviour (total sitting time, standing, and stepping), cardiometabolic risk markers, physiological stress (cortisol levels), physical health (self-report and postural stability), psychological wellbeing and mood, work stress (self-reported), and work performance (job satisfaction and productivity).

Detailed Description

Prolonged sedentary behaviour is associated with a higher incidence of cardiovascular disease and type 2 diabetes. A large proportion of daily sedentary time (sitting) occurs in the workplace. On average, full time office workers spend upwards of 70% of their working day seated with the majority of this time accumulated in sitting bouts ≥ 20 minutes. A recent cross-sectional investigation into the occupational characteristics of over 5,000 British police force employees reported at least 30% identifying as having mainly office-based duties. When trying to reduce prolonged sitting in the workplace, one of the most effective strategies is the use of multi-component interventions. At the present time, sedentary workplace intervention studies in the police are limited.

The primary aim of this study is to assess the feasibility of an intervention to reduce and break up prolonged sitting time at work in full-time police staff. The secondary aims of this study are to assess preliminary effects on sedentary behaviour, cardiometabolic risk markers, physiological stress, physical health, psychological wellbeing and mood, work stress, and work performance.

This has a single-arm, pre-post study design. Participants will receive a multi-component intervention to break up and reduce prolonged sitting including: a presentation/workshop, electronic support, minor environmental modifications, organisational support, and team competition. Assessments will take place at baseline and post-intervention (week 10).

Study Groups

Intervention

The intervention group will aim to regularly break up participants' prolonged sitting time with three-minute incidental movement breaks every half hour at work. Support for behaviour change will include a lecture/workshop, electronic prompts, break logging, team competition, health champions, and email support.

Group Type: EXPERIMENTAL

Breaks

Intervention Type: BEHAVIORAL

3-min breaks every half hour at work
