Prolonged sitting increases the risk of cardio-metabolic disease. Office-based employees are particularly susceptible to high rates of this sedentary behaviour during work hours. Laboratory studies indicate that regularly interrupting periods of prolonged sitting with short bouts (2 min) of physical activity can improve markers of cardio-metabolic health. This method of interrupting sitting time is yet to be tested in an occupational setting and may provide an alternative to providing sit-to-stand desks. Drawing on the Behaviour Change Wheel and evidence on the barriers and motivators to performing regular activity breaks, the Move More @ Work intervention was developed. The objectives of this pilot study are to examine the feasibility, and preliminary outcomes, of this intervention designed to encourage participants to perform 1–2 min of activity after every 30 min of continuous sitting throughout the work day. The study will inform if progress to a full effectiveness trial is warranted. An interrupted time series design consisting of a 4-week baseline (control period), a 12-week intervention, and a 12-week follow-up will be utilised. At least 57 university employees who self-report spending > 5 h per day sitting at work on at least 3 days per week will be recruited to participate. The intervention consists of (1) a structured consultation with a Move More @ Work coach, containing a number of behaviour change techniques to create an individualised plan of how to incorporate the activity breaks into the working day, and (2) strategies to create a supportive workplace culture for performing the activity breaks. Feasibility will be assessed by recruitment and retention rates, and acceptability of the intervention. Pilot outcomes are the number of regular activity breaks taken during the workday, cardio-metabolic risk score and self-reported health, and work-related productivity outcomes. If the Move More @ Work intervention is shown to be feasible, acceptable, and shows evidence of effectiveness, this will provide justification for the progression to a full scale evaluation of the intervention. In the longer-term, this intervention may provide an alternative means of improving health outcomes through interrupting sedentary time than that offered by current sedentary behaviour interventions.

用于评估 Move More @ Work 干预措施可行性的试点试验协议，以鼓励员工在每坐 30 分钟后抓住机会移动（身体活动）

久坐会增加心脏代谢疾病的风险。在办公室工作的员工在工作时间特别容易受到这种久坐行为的影响。实验室研究表明，定期打断长时间坐着进行短时间（2 分钟）的体力活动可以改善心脏代谢健康指标。这种打断坐下时间的方法尚未在职业环境中进行测试，可能会提供一种替代提供坐到站办公桌的方法。利用行为改变轮以及有关执行定期活动休息的障碍和激励因素的证据，开发了 Move More @ Work 干预措施。这项试点研究的目的是检查可行性和初步结果，这项干预旨在鼓励参与者在整个工作日每连续坐 30 分钟后进行 1-2 分钟的活动。该研究将告知是否需要进行全面有效性试验。将使用由 4 周基线（对照期）、12 周干预和 12 周随访组成的间断时间序列设计。将招募至少 57 名自我报告每天花费 > 5 小时，每周至少 3 天上班的大学员工参加。干预包括 (1) 与 Move More @ Work 教练的结构化咨询，其中包含许多行为改变技巧，以制定如何将活动休息时间融入工作日的个性化计划，(2) 为执行活动休息创造支持性工作场所文化的策略。可行性将通过招募和保留率以及干预的可接受性进行评估。试点成果是工作日期间定期活动的次数、心脏代谢风险评分和自我报告的健康状况，以及与工作相关的生产力成果。如果 Move More @ Work 干预被证明是可行的、可以接受的，并且显示出有效性的证据，这将为干预的全面评估提供依据。从长远来看，与目前的久坐行为干预相比，这种干预可能提供一种通过中断久坐时间来改善健康结果的替代方法。澳大利亚新西兰临床试验注册中心，ACTRN12620000354987。
