Background: With the rapid growth of mobile technology, ensuring accessibility and usability for older adults has become a critical concern. This systematic review evaluates existing age-friendly mobile app design research, identifying key usability barriers and effective strategies for improving accessibility. Methods: This study reviews English-language research (Published between Jun. 2014 and Mar. 2025) on mobile applications for adults aged 60 + , focusing on user-centered design, usability testing, and age-friendly adaptations. It compares different levels of accessibility features and evaluates their impact on usability, satisfaction, and engagement across various settings. Studies were retrieved from four online databases (PubMed, Scopus, Web of Science, and IEEE Xplore). Results: This systematic review initially reviewed 1,556 records. From these, 132 articles met the inclusion criteria. The findings highlight several essential design elements, including simplified navigation, enlarged text and touch targets, voice interaction, and error-tolerant interfaces. Participatory design methods enhanced usability and satisfaction, demonstrating the importance of co-designing applications with older users. However, challenges like cognitive overload, lack of digital literacy, and accessibility barriers persist. Conclusion: The review emphasizes the need for future research on Artificial Intelligence-driven personalization, long-term usability studies, and culturally inclusive mobile applications. By integrating age-friendly design principles, developers can enhance digital inclusion, promote independence, and improve the overall well-being of older adults in an increasingly digital world.

Introduction: Improving well-being and overall system performance are the ultimate goals of ergonomics which are achieved through ergonomic interventions. This systematic review aimed to answer this question: What do the different ergonomic interventions accomplish in a workplace? Method: This systematic review followed the PRISMA guidelines. Ergonomic interventions in workplaces focusing on any ergonomics health outcomes or productivity were identified in electronic databases up to 1 Jun, 2019. Results: The 1635 articles collected from the literature screening stage were screened for their relevance to this study by the authors independently. The full-text review identified 22 papers qualified for inclusion in this systematic review. Most of the interventions implemented in the analyzed articles were ergonomic training programs, participatory ergonomics and workstation designs. The highlight results showed that interventions such as feedback, participatory ergonomics in short term follow-ups, and job rotation along with ergonomic guidelines, did not significantly affect the risk of psychosocial factors. A significant reduction of musculoskeletal disorders in the upper limbs was reported with workplace improvements. Conclusion: There was no specific study method or intervention approach found to influence ergonomic outcomes. A multicomponent intervention program can be used to improve the impact of interventions on employees’ health and system productivity.

Objectives. The increasing prevalence of musculoskeletal disorders (MSDs), especially in the neck and upper limbs, among office workers is an important issue related to health and job productivity. The present study aimed to evaluate the effect of an ergonomics training intervention on MSDs, quality of work-life and occupational psychosocial stresses among office workers. Methods. This quasi-randomized trial study was conducted in Isfahan, Iran in 2019. Outcome measures were measured in a follow-up period of 1, 3 and 6 months after the intervention. The results were analyzed using repeated-measures analysis of variance. Results. The interventions performed had a significant effect on neck, left shoulder, right wrist and left thigh discomfort. These interventions also had a significant effect on social support and physical job demands. Significant changes were detected in quality of work-life, chance of growth and security, social integration in organization and social relevance of work in life, although these changes decreased in quality of work-life. No significant differences were detected in the other measured outcomes. Conclusion. The implementation of ergonomic interventions was effective in reducing MSDs in the neck and upper limbs. It is recommended to conduct continuous training courses to control the risk of ergonomic factors affecting body discomfort.

Color and light are two ambient attributes for interior spaces that can be used in the design and modification of workspaces. The visual and psychological effects of color and light of each have been studied separately and widely. The aim of this study was to investigate the simultaneous effects of warm/cool white light on visual perception and mood in a simulated colored workspace. Thirty-three healthy male participants were recruited. They were asked to judge the visual perception and mood of three types of workspace that were designed by colors of white, red, blue, and lights of a cool and warm white in the random six sessions. The participants have experienced higher levels of tension, anger, depression, anxiety and lower levels of visual comfort, attractiveness, brightness and calmness of environment in the red condition than to white in both state of light. The blue wall reduced brightness and increased attractiveness of environment compared to white wall. Cool white light reduced the warmth of color and increased brightness in all three color environments compared to warm light. The preference for cool or warm light depends on the color of the environment's indoor surface. It seems that the combination of the white color and warm light or the blue color with cool light has a more favorable effect on visual perception and people's mood in workplaces.

Background and Objective: The sudden emergence of coronavirus disease 2019 (COVID-19) may lead to anxiety due to this disease among hospital staff. Therefore, the present study aimed to investigate the anxiety caused by COVID-19 and its relationship with burnout among hospital staff. Materials and Methods: This descriptive cross-sectional study was ...

Considering the increased mental workload in office jobs, this research aimed to evaluate the association between mental workload and musculoskeletal disorders (MSDs) by assessing the mediating role of fatigue and sleep quality in office personnel. In this cross-sectional study we applied the structural equation modeling. The research population included office personnel of a healthcare in Borujerd, Iran, 243 of whom were selected via simple random sampling. Research tools included CMDQ, SOFI, PSQI, and SWAT. In addition, data analysis was performed in SPSS version 18 and AMOS version 18. Our findings showed a significant correlation between mental workload and sleep quality and fatigue with MSDs (P ≤ 0.05). The model proposed in this study had a proper goodness of fit, which demonstrated the mediating role of variables of fatigue and sleep quality in the relationship between mental workload and MSDs. According to the results of the study, the incidence of MSDs could be reduced by decreasing mental workload, fatigue and sleep quality.
