Methods: Institution based cross-sectional quantitative study was conducted. A simple random sampling technique was used to select the samples of 428 participants. Data were collected through the face to face interview administered questionnaire.

The prevalence of work related musculoskeletal disorders among vehicle maintenance workers was found to be 51.5% in the last 12 months. The risk factors of the WMSDs that were identified as lifting heavy object [AOR:3.5, 95%CI(1.452,8.586)], professional training [AOR:0.562,95%CI(0.37,0.910)] and monthly salary [AOR:2.4 ,95%CI(1.672,3.841)].
