Detailed Description
Study objectives: This study aims to provide a cost-effective solution to reducing sitting time during the workday, through provision of (1) low-cost cardboard standing desks ($20), and (2) simple behaviour change strategies (e.g., instruction on how to break up sitting time and information on the health consequences of doing so).
Background: Sedentary behaviour, defined as 'any waking behaviour characterised by an energy expenditure ≤1.5 metabolic equivalents while in a sitting, reclining, or lying posture', is a risk factor for poor health, independent of moderate-to-vigorous physical activity (MVPA). High levels of sedentary behaviour and excessive bouts of prolonged sitting is associated with increased risk for developing type 2 diabetes, cardiovascular disease and some cancers.
Sedentary behaviours are prevalent among Canadian adults, who often spend a large proportion of their waking hours sitting (e.g., work, commuting, watching TV), and office workers have been identified as one of the most sedentary occupational groups. Sedentary behaviour can be reduced by replacing sitting time with standing or light ambulation. In order to do so, it is vital to create an environment that makes sitting less likely and standing/moving easier. There is some evidence that introduction of sit-stand desks can reduce occupational sitting time within office environments ; however, there are cost barriers to the provision of these desks in work environments and few randomized control trials have demonstrated the long-term compliance and effectiveness of these desks on health- (e.g., weight, waist circumference, blood-derived biomarkers, musculoskeletal symptoms, fatigue) and work-related (e.g., work performance/productivity) outcomes. These are important factors that need to be considered and studied in further detail to quantify the benefit of sit-stand workstations.
Therefore, the purpose of this study is to evaluate the long-term effectiveness of a low-cost intervention aimed at reducing workplace sitting time in office workers.
Primary objectives:
• To evaluate the effectiveness of the intervention at reducing daily occupational sitting time over 6 months.
Secondary objectives:
• To explore whether the intervention results in improvements in work engagement and productivity, and occupational fatigue.
Methods/Design: The intervention will be delivered and evaluated over a 6-month period. This study is a two-arm randomized waitlist-controlled trial with one intervention group and one control group. After eligibility assessment, individuals will be randomly allocated to either the intervention or the control arm. The experimental group participants will receive a low-cost cardboard standing desk converter in their regular office environment and behaviour change strategies to break up sitting time, while the control group participants will not encounter any change to their regular work environments or be provided with any behaviour change strategies.
Intervention for experimental group:
Each participant allocated to the experimental group will receive a low-cost, cardboard, fixed-height standing desk converter (https://oristand.co/) that will be placed in their regular office environment, along with their usual sitting desk. The participants will be instructed on how to use the fixed-height standing desk converter (herein referred to as standing desk) as a way to break up sitting time every 30 minutes. In addition, each participant will be provided with information about the health benefits of breaking up sitting time.
Waitlist Control group:
Control group participants will not encounter any changes to their regular office environment. They will be provided with the standing desk and behaviour change strategies 6-months post-intervention.

Experimental: Standing Desk Intervention
Each participant allocated to the experimental group will receive a low-cost, cardboard, fixed-height standing desk converter (https://oristand.co/) that will be placed in their regular office environment, along with their usual sitting desk.
The participants will be instructed on how to use the fixed-height standing desk converter (herein referred to as standing desk) as a way to break up sitting time every 30 minutes.
In addition, each participant will be provided with information about the health benefits of breaking up sitting time.

Other: Waitlist Control
Control group participants will not encounter any changes to their regular office environment.
They will be provided with the standing desk and behaviour change strategies 6-months post-intervention.

Work engagement
Time Frame: Baseline, 3 months and 6 months

Utrecht Work Engagement Scale (UWES).
Work engagement will be measured using the Utrecht Work Engagement Scale (UWES), a 7-point likert scale ("never" [0]to "always" [6]).
There are three sub-scales: vigour, dedication, and absorption.
The mean scale score of the three UWES subscales is computed by adding the 3 scores on each particular scale and dividing the sum by the number of items of the subscale involved.
A similar procedure is followed for the total score.
Hence, the UWES yields three subscale scores and/or a total score that range between 0 and 6.
Higher values reflect better outcomes.

Baseline, 3 months and 6 months
|
Occupational fatigue
Time Frame: Baseline, 3 months and 6 months
|
Need for Recovery (NFR) scale.
Occupational fatigue will be measured using the 11-item Need for Recovery (NFR) scale.
Indicators of fatigue assessed on the NFR scale include a lack of concentration and reduced motivation for activities at the end of the day.
Participants are given dichotomous response options (yes/no) to answer whether or not they experience each indicator.
The total number of indicators present for each individual is converted into a scale score which ranges from 0 to 100, where higher scores show a greater need for recovery and thereby greater short-term work-related fatigue.
