Large volumes of sitting time have been associated with multiple health risks. To reduce sitting time of office workers working for a Dutch insurance company, the Dynamic Work intervention was developed. The primary objective of this paper is to describe the study protocol of the Dynamic Work study, which aims to evaluate if this multicomponent intervention is (cost-)effective in reducing total sitting time on the short-term (≈3 months) and longer-term (≈12 months) compared to usual practice.
METHODS/DESIGN: This two-arm cluster randomized controlled trial will recruit 250 desk-based office workers working at different locations of an insurance company in the Netherlands. After baseline measurements, departments will be matched in pairs and each pair will be randomly assigned to the control or intervention condition. The multicomponent intervention contains organizational (i.e. face to face session with the head of the department), work environmental (i.e. the introduction of sit-stand desks and cycling workstations), and individual elements (i.e. counselling and activity/sitting tracker with a self-help program booklet). The counselling involves two group intervention sessions and four on-site department consultations with an occupational physiotherapist. Sitting time (primary outcome), upright time and step counts will be assessed objectively using the activPAL activity monitor at baseline, short-term (approximately 3 months) and longer-term (12 months). Other outcomes will include: self-reported lifestyle behaviours, anthropometrics, work-related outcomes (i.e. absenteeism, presenteeism, work performance, work-related stress), health-related outcomes (i.e. vitality, musculoskeletal symptoms, need for recovery, quality of life), and costs from both company and societal perspective. The study will include economic and process evaluations.
This study will assess the longer-term (cost-) effectiveness of a multicomponent workplace intervention aimed at reducing sitting time in comparison with usual practice. Furthermore, the process evaluation will provide insights in factors associated with successful implementation of this intervention.

大量的久坐时间与多种健康风险相关。为了减少在荷兰一家保险公司工作的上班族的久坐时间，开发了动态工作干预。本文的主要目的是描述动态工作研究的研究方案，该研究旨在评估这种多组分干预措施在短期内（约 3 个月）和长期内（约 12 个月）相对于常规实践是否能（成本）有效减少总久坐时间。
方法/设计：这是一项双臂随机对照临床试验，将招募 250 名在荷兰一家保险公司不同地点工作的伏案上班族。在基线测量后，部门将进行配对，每对将随机分配到对照组或干预组。该多组分干预措施包含组织（即与部门主管进行面对面会议）、工作环境（即引入坐站两用办公桌和骑行工作站）和个人元素（即咨询和活动/坐姿跟踪器以及自助计划手册）。咨询包括两次小组干预会议和四次现场部门咨询，由职业理疗师进行。使用 activPAL 活动监测器在基线、短期（约 3 个月）和长期（12 个月）评估久坐时间（主要结果）、直立时间和步数。其他结果包括：自我报告的生活方式行为、人体测量学、工作相关结果（即缺勤、在职病假、工作表现、工作相关压力）、健康相关结果（即活力、肌肉骨骼症状、恢复需求、生活质量）以及公司和社会视角的成本。该研究将包括经济和过程评估。
该研究将评估旨在减少与常规实践相比，减少久坐时间的多组分工作场所干预的长期（成本）有效性。此外，过程评估将提供与该干预措施成功实施相关的因素的见解。
