OBJECTIVE: This study aimed to investigate the prevalence and factors associated with work-related musculoskeletal disorders among cashiers in small-scale businesses in Northwestern Ethiopia.
DESIGN: A multicentre cross-sectional study was conducted from July to September 2022. The data were collected using a validated and standardised Nordic Musculoskeletal Questionnaire. The collected data were entered into EpiData V.4.6 and analysed using Stata V.14. A multivariable logistic regression analysis was used to ascertain the significance of associations at p<0.05 and the adjusted OR (AOR) with a 95% CI.
SETTING: The study was conducted in small-scale businesses in the North Gondar Zone.
PARTICIPANTS: A total of 618 cashiers participated in this study.
OUTCOME MEASURES: The primary outcome of the study is the prevalence of work-related musculoskeletal disorders, which was measured using the Nordic Musculoskeletal Questionnaire.
RESULTS: The response rate was 97.5% (N=618). The majority (373; 60.4%) of the study participants were female. The mean (±SD) age of the participants was 30 (±8.3) years. The prevalence of work-related musculoskeletal disorders during the last 12 months was found to be 75.4% (n=466) (95% CI 71.8%, 78.8%). Marital status (married) (AOR=2.12; 95% CI 1.26, 3.56), lack of physical exercise (AOR=2.07; 95% CI 1.32, 3.23), alcohol consumption (AOR=3.55; 95% CI 2.18, 5.78) and awkward work posture (AOR=2.40; 95% CI 1.43, 4.0) were significant factors associated with work-related musculoskeletal disorders among sampled cashiers.
CONCLUSION: This study concluded that the overall prevalence of work-related musculoskeletal disorders was high among cashiers in small-scale businesses. Being married, a lack of physical exercise, alcohol consumption and awkward work posture were significant factors of work-related musculoskeletal disorders. To reduce work-related musculoskeletal disorders, it is recommended taking part in physical activity, avoiding alcohol consumption and avoiding awkward work posture.
