Interventionen zur Reduzierung sitzenden Verhaltens am Büroarbeitsplatz – eine systematische Literaturanalyse

Abstract

Sedentary behaviour is a health risk factor independent of physical activity. Interventions that aim to reduce sitting at the workplace are particularly important as office workers spend a large proportion of their working hours sitting. This systematic review examines whether these interventions (SB or PA interventions during work time) reduce sitting time among office workers and which variables moderate intervention effects. A systematic literature search was conducted from April to May 2016 in the following databases: PubMed, PsycINFO and SPORTDiscus. In total, we identified 17 studies that assessed the time spent in sedentary behaviour at the office workplace. To summarize the study results, we applied a best-evidence synthesis. Additionally, we evaluated potential moderators, such as intervention strategies. Multi-component interventions and sit-stand workstations were most promising sedentary reduction interventions. The analysis of moderators highlighted that the proportion of positive intervention effects was higher in interventions based on the strategies "environmental restructuring", "adding objects to the environment" and "instructions on how to carry out the behaviour". Furthermore, interventions focusing on sedentary behaviour only and studies using objective measurement tools showed more often positive interventions effects. There are many promising interventions to reduce sitting time at the office workplace. However, there is insufficient evidence if the effects of these interventions are sustainable in the long term. Moreover, the considerable heterogeneity of included studies limits the validity of our findings. Future intervention studies should build on a theoretical planning approach and use subjective as well as objective evaluation measures.

Workshop Gesundheitsgefährdung durch langes Sitzen am Arbeitsplatz – Teil I wissenschaftliche Perspektiven

“…Letztere Studien sind jedoch sehr heterogen [34]. Insgesamt wird dieses auch in weiteren Übersichtsarbeiten geschlussfolgert, und der Ruf nach Studien mit längerem Nachuntersuchungszeitraum, höherer Probandenzeit und Studienqualität wird einstimmig gefordert [36,45,46].…”

“…Die Heterogenität wird derzeit selten über eine fehlende Theorieorientierung diskutiert [46,47]. Dies verwundert, da theoriebasierte Interventionen durchaus eine höhere Wirksamkeit zugeschrieben wird.…”

Systematic Review of the Influence of Physical Work Environment on Office Workers’ Physical Activity Behavior

“…For example, systematic reviews of work environments have considered the relationship between desk type and heart rate, blood pressure, cardiometabolic risk factors, body mass index (BMI), work productivity, and mood (MacEwen et al, 2015), or open-plan workspaces work environments and health components such as sickness absences, job satisfaction, job concentration, work fatigue, or musculoskeletal disorders (De Croon et al, 2005;Richardson et al, 2017). Numerous studies have considered the work environment and reducing sedentary behavior at work (Becker et al, 2019;Chau et al, 2016;MacEwen et al, 2015;Neuhaus et al, 2014;Tew et al, 2015). However, no systematic reviews have focused on the relationship between physical activity and physical or structural office design components (desk, office layouts, floor plans, and building design) of the work environment.…”

Moving to an “Active” Biophilic Designed Office Workplace: A Pilot Study about the Effects on Sitting Time and Sitting Habits of Office-Based Workers

“…However, a Cochrane review concluded that evidence that sit-and-stand desks reduce sitting time at work was of low quality [18]. Further systematic reviews and meta-analyses of workplace intervention strategies argue that the combination of educational/behavioral and environmental interventions, referred to as multicomponent interventions, are the most promising for reducing sitting time [18,19,20].…”
