The purpose of this investigation was to systematically review work site-based, environmental interventions to reduce sedentary behavior following preferred reporting items for systematic reviews and meta-analyses guidelines.
Data were extracted from Medical Literature Analysis and Retrieval System Online, Cochrane Central Register of Controlled Trials, and Web of Science between January 2005 and December 2015.
Inclusion criteria were work site interventions, published in peer-reviewed journals, employing environmental modalities, targeting sedentary behavior, and using any quantitative design. Exclusion criteria were noninterventions and non-English publications.
Data extracted included study design, population, intervention dosage, intervention activities, evaluation measures, and intervention effects.
Data were tabulated quantitatively and synthesized qualitatively.
A total of 15 articles were identified for review and 14 reported statistically significant decreases in sedentary behavior. The majority of studies employed a randomized controlled trial design (n = 7), used inclinometers to measure sedentary behavior (n = 9), recruited predominantly female samples (n = 15), and utilized sit-to-stand desks as the primary intervention modality (n = 10). The mean methodological quality score was 6.2 out of 10.
Environmental work site interventions to reduce sedentary behavior show promise because work sites often have more control over environmental factors. Limitations of this intervention stream include inconsistent measurement of sedentary behavior, absence of theoretical frameworks to guide program development, and absence of long-term evaluation. Future studies should include clear reporting of intervention strategies and explicit operationalization of theoretical constructs.
本调查旨在按照系统评价与Meta分析优先报告项目指南，对基于工作场所的环境干预措施进行系统评价，以减少久坐行为。
数据于2005年1月至2015年12月期间从医学文献分析与检索系统在线数据库、Cochrane对照试验中心注册库以及科学网中提取。
纳入标准为发表在同行评审期刊上、采用环境方式、针对久坐行为且使用任何定量设计的工作场所干预措施。排除标准为非干预措施和非英文出版物。
提取的数据包括研究设计、人群、干预剂量、干预活动、评估措施和干预效果。
数据进行了定量制表和定性综合。
共识别出15篇文章进行综述，其中14篇报告久坐行为有统计学意义的下降。大多数研究采用随机对照试验设计（n = 7），使用倾角计测量久坐行为（n = 9），主要招募女性样本（n = 15），并将坐站两用桌作为主要干预方式（n = 10）。方法学质量平均得分为6.2分（满分10分）。
基于工作场所的环境干预措施在减少久坐行为方面显示出前景，因为工作场所通常对环境因素有更多控制。该干预措施系列的局限性包括久坐行为测量不一致、缺乏指导项目开发的理论框架以及缺乏长期评估。未来的研究应包括清晰报告干预策略以及明确理论构建的操作化。
