Effectiveness of the Stand More AT (SMArT) Work intervention: cluster randomised controlled trial
多站(智能)工作干预的有效性:整群随机对照试验

Objectives: To evaluate the impact of a multicomponent intervention (Stand More AT (SMArT) Work) designed to reduce sitting time on short (three months), medium (six months), and longer term (12 months) changes in occupational, daily, and prolonged sitting, standing, and physical activity, and physical, psychological, and work related health.
目的:评估多成分干预 (站立更多 at (smart) 工作) 的影响, 该干预措施旨在减少职业、日常和长时间的短期 (3个月)、中期 (6个月) 和长期 (12个月) 的坐姿变化,站立、体育活动、身体、心理和工作相关的健康。

Design: Cluster two arm randomised controlled trial.
设计:集群两臂随机对照试验。

Setting: National Health Service trust, England.
建立者:国家卫生服务信托基金, 英格兰。

Participants: 37 office clusters (146 participants) of desk based workers: 19 clusters (77 participants) were randomised to the intervention and 18 (69 participants) to control.
参与者:37个办公室群组 (146名参与者) 的办公桌工人: 19个分组 (77名参与者) 随机干预, 18 (69 参与者) 控制。

Interventions: The intervention group received a height adjustable workstation, a brief seminar with supporting leaflet, workstation instructions with sitting and standing targets, feedback on sitting and physical activity at three time points, posters, action planning and goal setting booklet, self monitoring and prompt tool, and coaching sessions (month 1 and every three months thereafter). The control group continued with usual practice.
干预:干预小组收到了一个高度可调的工作站、一个带有辅助传单的简短研讨会、有坐姿和站立目标的工作站说明、三个时间点的坐姿和体育活动反馈、海报、行动规划和目标设定手册、自我监控和提示工具以及辅导课程 (第1个月和此后每三个月)。对照组继续进行常规练习。

Main outcome measures: The primary outcome was occupational sitting time (thigh worn accelerometer). Secondary outcomes were objectively measured daily sitting, prolonged sitting (≥30 minutes), and standing time, physical activity, musculoskeletal problems, self reported work related health (job performance, job satisfaction, work engagement, occupational fatigue, sickness presenteeism, and sickness absenteeism), cognitive function, and self reported psychological measures (mood and affective states, quality of life) assessed at 3, 6, and 12 months. Data were analysed using generalised estimating equation models, accounting for clustering.
主要结果:测量主要结果是职业坐姿时间 (大腿磨损加速度计)。对次要结果进行客观测量, 每天坐坐, 长时间 (≥ 30分钟), 站立时间, 体育活动, 肌肉骨骼问题, 自我报告的工作相关的健康 (工作表现, 工作满意度, 工作参与,职业疲劳、疾病先见之明和疾病旷课)、认知功能和自我报告的心理措施 (情绪和情感状态、生活质量) 评估为3个月、6个月和12个月。利用广义估计方程模型对数据进行了分析, 并对聚类进行了核算。

Results: A significant difference between groups (in favour of the intervention group) was found in occupational sitting time at 12 months (−83.28 min/workday, 95% confidence interval −116.57 to −49.98, P=0.001). Differences between groups (in favour of the intervention group compared with control) were observed for occupational sitting time at three months (−50.62 min/workday, −78.71 to −22.54, P<0.001) and six months (−64.40 min/workday, −97.31 to −31.50, P<0.001) and daily sitting time at six months (−59.32 min/day, −88.40 to −30.25, P<0.001) and 12 months (−82.39 min/day, −114.54 to −50.26, P=0.001). Group differences (in favour of the intervention group compared with control) were found for prolonged sitting time, standing time, job performance, work engagement, occupational fatigue, sickness presenteeism, daily anxiety, and quality of life. No differences were seen for sickness absenteeism.
结果:组间 (有利于干预组) 在 12个月 (-83 例) 职业坐姿时间上存在显著差异。28工作日, 95% 置信区间-11点57至-49.98, pce/0.001)。在三个月 (-50.62 min/工作日,-在城/-22.5, p. < 0.001) 和 6个月 (-64.40 min/day,-97.31 至-31.50, 50.62) 和 6个月 (-64.40 min/50, 50.62) 和6个月的职业坐姿时间观察到各组之间的差异 (有利于干预组与对照组的比较) 和每日坐姿时间为 6个月 (-593.32 分钟,-8840 至-30.25, p< a0-001) 和 12个月 (-88.40 分钟,-114.54 至-50.26, pcd 0.001)。群体差异 (有利于干预组与对照组相比) 的特点是长时间的坐姿、站立时间、工作表现、工作参与、职业疲劳、疾病预感、日常焦虑和生活质量。在疾病缺勤方面没有发现任何差异。

Conclusions: SMART Work successfully reduced sitting time over the short, medium, and longer term, and positive changes were observed in work related and psychological health.
结论: SMART工作在短期、中期、长期内成功缩短了坐姿时间, 观察到工作相关和心理健康方面的积极变化。
