Musculoskeletal disorders among taxi drivers: a systematic review and meta-analysis

Abstract

Introduction: Taxi drivers, as professional drivers, encounter numerous ergonomic risk factors related to musculoskeletal disorders (MSDs) because of the demands of their jobs. This study conducted as a systematic review and meta-analysis aimed to explore the prevalence of MSDs among taxi drivers. Materials and methods: The present study followed the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, and its protocol was registered in the international prospective register of systematic review (PROSPERO) under the code CRD42024509258. Searches were carried out using various databases, such as PubMed, Scopus, Web of Science, Science Direct, SID, ISC, and Google Scholar, with no time restrictions until February 7th, 2024. A random effects model was utilized for meta-analysis, and the I2 index was employed to assess heterogeneity among studies. Lastly, data analysis was conducted using STATA software (version 14). Results: After the initial search, 1606 articles were extracted from the reviewed sources. Following screening, study selection, and quality evaluation, a total of 11 studies were chosen for meta-analysis, involving 5277 taxi drivers. Based on the results of the meta-analysis, the highest prevalence of MSDs among taxi drivers was related to the lower back region (53.87% (95% CI:40.89–66.84, I2= 98.7%, P < 0.001)). Additionally, the prevalence rates of MSDs in different body regions, such as the neck (38.15%), shoulder (34.97%), upper back (18.30%), and knee (14.10%), were also reported. Conclusion: Based on the findings of this study, the prevalence of MSDs among taxi drivers is relatively high, and specific risk factors may contribute to the development of these disorders. Therefore, to prevent the occurrence of MSDs among taxi drivers, it is advisable to implement essential measures concerning the development of training programs, ergonomic interventions, and evaluation of the work environment.
