Abstract

Background: Construction industries that focus on project-based nature, pressure, and long hours may lead to job-related stress among workers. In many emerging nations, robust economic growth plans generate occupational depression, anxiety, and stress among construction industry personnel. This study aims to determine the relationship between these items and the risk factors (demographic) among Malaysian construction professionals. Methods: A cross-sectional study was carried out among 173 Malaysian construction professionals. A DASS-21 questionnaire is used to survey eligible respondents. Results: Findings show that construction professionals have a high level of stress (54.9%), anxiety (48.5%), and depression (37%). Gender is significantly associated with stress (p = 0.000) and depression (p = 0.000). In turn, stress (p = 0.038), anxiety (p = 0.000), and depression (p = 0.001) all demonstrate a significant relationship with health status Conclusions: Health status is the risk factor most significantly associated with occupational stress. Given the findings, construction managers can help protect their employees and their mental health by promoting a healthy workplace through stress management and social activities.

Abstract

Background: Commuting stress is a growing concern for workers with long daily journeys between home and work. This study explores the effects of commuting on workers’ mental and physical health, focusing on stress, mental fatigue, and productivity at work. Methods: The research conducted in Selangor, Malaysia, involved 212 commuters who completed a survey that included sociodemographic and commuting information, the Depression Anxiety and Stress Score (DASS-21), and a mental fatigue questionnaire. Results: The findings revealed that a significant proportion of workers experienced stress from their commuting routines: approximately 74.5% reported that commuting had a detrimental effect on their mental health, while 82.1% experienced mental fatigue, which directly impacted their ability to concentrate and perform effectively at work. The DASS-21 results showed that 14.2% experienced mild depression, 16% had moderate anxiety, and 11.4% reported mild stress. A significant positive correlation was found between commuting distance and anxiety (r = 0.35, p < 0.05), stress (r = 0.32, p < 0.01), and mental fatigue (r = 0.42, p < 0.05). Conclusions: Commuting stress adversely affects concentration, productivity, and well-being. The study suggests adopting telework, flexible work hours, and workplace mental health initiatives to mitigate these negative effects.

Abstract

Introduction: The discrepancy between actual heat stress and workers' perception results in a mitigation failure, potentially leading to fatality. This study aimed to investigate workplace heat stress, workers' workload, and personnel's heat strain in steel mills under extreme temperature conditions. Methods: The study used a mixed-methods design and was conducted across three steel mills in East Java, Indonesia. An analysis of heat-stress data included heat-stress symptoms derived from physiological and environmental factors, while the personal perception assessment was based on comprehensive interview sessions. These quantitative results, obtained from 119 operators, were compared with workers' personal thermal perceptions using a mixed-methods approach. Phase 1 quantitative method consisted of onsite data collection, walkthrough inspection, questionnaire distribution, workplace monitoring, personal assessment, and statistical analysis. Phase 2, as a qualitative stage, consisted of in-depth interviews and focused group discussions with 15 participants. Results: The wet-bulb globe temperature measurements confirm significant heat stress in all mills. Workers' physiological responses remained within acceptable limits according to ACGIH criteria. However, a noticeable discrepancy was found between the quantitative data and workers' perceptions, highlighting the need for greater awareness and training on heat-stress hazards. Conclusion: The alignment between qualitative and quantitative findings underscores the importance of integrating both approaches to develop effective mitigation strategies. This study contributes to understanding occupational heat stress in high-risk environments and emphasizes the need to incorporate worker perceptions into health and safety protocols.
