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).

Conditions

Sedentary Behavior; Metabolic Syndrome; Affect; Stress, Physiological; Stress, Psychological; Musculoskeletal Pain

Outcome Measures

Primary Outcomes (2)

• Feasibility - Adherence: Drop-out rates in control and intervention group

  Analyses of drop-out rates (%) in control and intervention group.

  From recruitment (typically 4 weeks prior to baseline) up to study completion (typically 12 weeks)

• Feasibility - Acceptability: Perceptions of the intervention

  Asking participants' to qualitatively reflect on the intervention via semi-structured interview.

  At week 11

Secondary Outcomes (30)

• Change in the number of breaks (sit-stand transitions) from sedentary time per hour (workplace and daily)

  This measure will be assessed at baseline and 10 weeks. At each time point the accelerometer will be worn for 7 days.

• Change in sitting time accrued in prolonged bouts (≥ 30 minutes) (workplace and daily)

  This measure will be assessed at baseline and 10 weeks. At each time point the accelerometer will be worn for 7 days.

• Change in the average duration (minutes) of prolonged sitting bouts (≥ 30 minutes) (workplace and daily)

  This measure will be assessed at baseline and 10 weeks. At each time point the accelerometer will be worn for 7 days.

• Change in the number of prolonged sitting bouts (≥ 30 minutes) (workplace and daily)

  This measure will be assessed at baseline and 10 weeks. At each time point the accelerometer will be worn for 7 days.

• Change in the total duration (minutes) of sitting time (workplace and daily)

  This measure will be assessed at baseline and 10 weeks. At each time point the accelerometer will be worn for 7 days.

Study Arms (1)

Intervention

EXPERIMENTAL

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.

Behavioral: Breaks

Interventions

Breaks BEHAVIORAL

3-min breaks every half hour at work

Intervention
