Cross-sectional study evaluates work-related musculoskeletal disorders and stress in delivery personnel, suggesting significant health risks from long hours and inadequate sleep.
Background: Delivery personnel frequently work long hours under time pressure and irregular schedules, increasing their vulnerability to work-related musculoskeletal disorders (WRMSDs) and workplace stress. This study evaluated the frequency and determinants of WRMSDs and occupational stress among delivery personnel in Chennai. Methods: A cross-sectional study was carried out with 200 delivery workers who were selected using snowball sampling. Structured interviews were used to gather information. WRMSDs were assessed using the Nordic Musculoskeletal Questionnaire and workplace stress using the Workplace Stress Scale (score >20 indicating high stress). Logistic regression and chi-square tests were analysed. Results: WRMSDs were reported by 54% of participants, predominantly involving the lower back and workplace stress was identified in 46%. Significant predictors of workplace stress included full-time employment (AOR: 3.88; 95%CI: 1.66-9.05), working >8 hours/day (AOR: 3.52; 95%CI: 1.41-8.76), and sleeping <6 hours (AOR: 3.99; 95%CI: 2.04-7.79). WRMSDs were associated with low-income (AOR: 2.86; 95%CI: 1.16-7.05), inadequate sleep (AOR: 7.29; 95%CI: 3.57-14.88), and <2 years of experience (AOR: 0.46 95%CI: 0.22-0.96). Conclusion: Delivery personnel face considerable WRMSDs and workplace stress, influenced mainly by long work hours and inadequate rest.
