These issues arise from poor work design, unsafe and unhygienic conditions, lack of ergonomic practices, and inadequate occupational health and safety (OHS) services, which are common in low-middle-income countries, which remain underexamined among hospital sanitation workers (SWs) in eastern Ethiopia.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;This study aimed to assess WMSDs and associated factors among public hospital SWs in eastern Ethiopia.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Hospital based cross sectional study was conducted in eastern Ethiopia in 2023. A well-structured questionnaire prepared. The internal consistency (α value) for the prepared questions was 0.95. Simple random sampling was used to choose eight hospitals among a total of fourteen public hospitals in these areas. A single proportion formula long with design effect of 2.0 and 5% of non-response rate was calculate the sample size and obtained 791 SWs, which is approaching actual number of SWs within selected hospitals. Thus, all (809) of SWs were recruited for the study. Face-to-face interview was conducted. Epi Data version 3.1 was used for data entry and Stata version 17MP was used for the data analysis. Data quality was ensured through training of data collectors, language translation, pretesting, and adjusting for confounders. The robust Modified Poisson/MP regression was used to identify predictors of WMSDs. Bi-variate MP model was used to perform un-adjusted prevalence ratio (UPR). While, MP multi-variable was used to analysis the adjusted prevalence ratio (APR) for predictors with significant values of p ≤ 0.20. The results were deemed statistically significant at the two-tailed level with a 95% confidence interval (CI:95%) and a p-value of 0.05.
