Workplace stress and associated factors among vehicle repair workers in Hawassa City, Southern Ethiopia

Abstract

INTRODUCTION: Workplace stress is a public health problem worldwide. Studies focusing on work-related stress among vehicle repair workers are scarce in African countries. The current study aimed to determine the prevalence of self-reported workplace stress and associated factors among vehicle repair workers in Hawassa City, South Ethiopia. METHODS AND FINDINGS: A cross-sectional study design was employed among 347 vehicle repair workers from January 25 to February 22, 2019. Questionnaires were administered using interviews. Additional tools were used for weight and height measurements. The main findings were analyzed using descriptive statistics, bivariable, and multivariable logistic regression. The strength of association of variables was presented by odds ratio along with its 95% CI. The statistical assessments were considered significant at p<0.05. A total of 344 workers participated in the study. The prevalence of workplace stress among participants was 41.6% with 95% CI: (36.3-47.1). Factors associated with workplace stress were more than 10 years of work experience [AOR: 2.40; 95% CI (1.29-4.50)], work-related musculoskeletal disorder [AOR: 3.39; 95% CI (1.99-5.78)], squatting and lying work posture [AOR: 4.63; 95% CI (1.61-13.3)] and servicing large vehicles [AOR: 1.96; 95% CI (1.14-3.38)]. CONCLUSION AND RECOMMENDATIONS: This study showed that the overall prevalence of work-related stress was substantially high. The independently associated factors were workers' service years, symptoms of body pain, and the work environment. Preventive measures need to be implemented in vehicle repair workshops by focusing on work environment improvements.
