- Active workstations to improve job performance: a short reviewPublication . Maheronnaghsh, Sara; Vaz, Mário; Santos, JoanaModern changes in communication, transportation, domestic-intertainment technologies and workplaces are related to a substantial increase of sedentary living.This review was performed to summarize and analyze the studies investigating the impact of decreasing work sedentary time and implementing active workstations to improve work performance. This review was based on relevant articles published in Scopus, Medline, and Web of science from 2007 until 2017. The results of this brief review indicate statistically significant relationships between several interventions for increasing physical activity and employee work performance. Type of intervention and implementation procedure were identified as factors that can determine effects on the job performance. Some studies have shown interventions with positive influence on productivity, others suggest that it is feasible to implement a multi-component intervention such as Stand Up desk with high fidelity with no perceived decrease in productivity. In conclusion, more field studies are necessary to determine work performance and acceptance of dynamic workstations in a real work environment.
- Factors influencing workplace physical activity interventions: a short reviewPublication . Maheronnaghsh, Sara; Santos, Joana; Vaz, MárioIntroduction: Many occupations are characterized by sedentary behavior (SB) and lack of physical activity (PA). There is growing evidence that prolonged sitting is associated with multiple health risks, including musculoskeletal disorders, biomarkers of increased cardiovascular diseases, some forms of cancer. There is an increasing interest in changing the work environment by implementing various interventions to reduce barriers and promote physical activity. The aim of this short review is to identify factors that affected workers’ SB and/or PA to design appropriate interventions. Methodology The search was performed based on PRISMA statement methodology and was conducted in Scopus for articles and reviews published in scientific journals from 2010 until 2019 in English, usinga set of root keywords as “sedentary work,” “physical activity” and ”effectiveness intervention”. Results and discussion the review included 12 studies describing effective factors on PA in three categories: organizational factor, individual factor, and social factor. The main organizational factors found were: supportive workplace policies and resources, time for involvement in intervention, paying for activity, management support, work environment factors, and job type (passive jobs, and high-strain jobs). Interpersonal factors, knowledge include (educational level and information about physical activity guidelines) and some sociodemographic factors as individual factors associated with the physical work activity. Furthermore, social factors like social support and social norm have a significant effect on willing to do physical activity in workers. Some studies used “behavior change techniques” to find effective factors on physical activity for identifying the most appropriate interventions. Conclusion: Current evidence demonstrates that some individual, organizational and social factors influence work physical activity; therefore, they need to be considered in each population specifically, before choosing the intervention type. It can contribute to the increasing effectiveness of interventions intended to improve physical activity. Future research in this area should consider the association of various factors identified to enhance the effectiveness of interventions.
- Important factors in the effectiveness of interventions for decreasing occupational sedentary behavior (short review)Publication . Maheronnaghsh, Sara; Vaz, Mário; Santos, Joana; Abadi, Sara Shahedi AliOccupational sedentary behavior (SB) is an occupational risk and an independent predictor of poor health and mortality. The impact of implemented interventions in workplaces for reducing SB has been studied several times, and their outcomes have been investigated. The purpose of this study is to identify the factors that can increase the effectiveness of the interventions in workplaces. Methodology: The search was conducted in Scopus, PubMed, Web of Science and other resources for articles published in scientific journals from 2010 until 2019 in English, using a set of keywords as “sedentary behavior”, “physical activity”, ”effectiveness” “occupational” and ” intervention”. Results and discussion: The review included ten studies that examined the effectiveness of interventions on physical activity (PA) and/or SBs and searched about factors that have an impact on failure or success of interventions. Various factors were identified like individual, organizational, and social factors associated with the SB and PA. Supportive workplace policies, time for involvement in intervention, paying for activity, environment, and job type requirements were the main organizational factors. Also, Interpersonal and educational factors, and some sociodemographic factors associated with the PA. Furthermore, social factors have a significant effect on willingness to do PA in workers. Conclusion: Current evidence shows that some organizational, individual, environmental, and social factors influence work PA; therefore, before choosing the intervention, they need to be considered in each population individually.
- Methods for measuring association between intervention for increasing movement and productivityPublication . Maheronnaghsh, Sara; Santos, Joana; Marques, António Torres; Vaz, MárioThe purpose of this systematic literature review is to check papers to find the best method for measuring association between health interventions and productivity and find best intervention in workplace for increasing productivity. This systematic review was performed based on PRISMA statement methodology and performed on all papers about association between productivity with intervention for increasing physical activity, published from 2007 until June 2017. The search was limited to English language items. The results of this systematic review demonstrate that providing interventions for workers in various workplaces have a low to high affecting on productivity, as measured by objective and organization specific metrics or subjective and self-report questionnaires. The Analyze of result showed that using different methods simultaneously can make more accuracy and precision. Also it’s better that before filling the self-report questionnaires researchers train all workers about the purpose of the study.
- Methods of posture analysis for computer workersPublication . Maheronnaghsh, Sara; Santos, Joana; Vaz, M.Musculoskeletal disorders (MSDs) have been identified as a predisposing factor for lesser productivity and are considered to be a major occupational health problem contributing significantly to absenteeism, disability and loss of productivity. Computer users may develop musculoskeletal disorders due to the forces applied, muscle use, posture and wrist velocity and acceleration exposures during computer use. Work-related musculoskeletal disorders (WMSDs) in computer users cause substantial worker discomfort, disability and loss of productivity. The aim of this study is to review systematically the relevant literature on applicable posture analysis methods to computer workers. A bibliographic survey based on PRISMA statement methodology was performed. A review on different approaches for computer workers posture was accomplished and noted that the simultaneous utilization of the different methods allows achieving better posture analysis, compared to situations when each one of them was used individually.
- The Influence of Active Workstations on Work Performance, Productivity Indicators and Sedentary Time: A Systematic ReviewPublication . Ramos, Sofia; Maheronnaghsh, Sara; Vila-Chã, Carolina; Vaz, M.; Santos, JoanaThe most of strategies to promote physical activity in workplaces interfere with work tasks and many organizations declined these programs. The aim of this review is to understand the impact of the active workstations on the performance and productivity indicators, and also on the reduction of the sedentary time. This review applied PRISMA methodology. 389 studies were identified by searching the different databases and 12 studies were selected, fulfilling the screening and eligibility criteria. The implementation of active workstations did not have a significant impact in terms of performance and productivity. However, some of indicators revealed some positive changes, namely at sit-standing, walking and cycling conditions. All active interventions had positive effects on the reduction of sedentary work time. However, it is essential that active interventions have promising effects for employers accept the challenge.
