Abstract Background: Low back pain prevalence is somewhat higher in the wealthier countries (42% vs. 35%). But, the epidemiological information regarding the prevalence and associated risk factors of low back pain among universities, colleges and school teachers in Ethiopia are unknown. Thus the aim of this study is to investigate the prevalence and associated risk factors of low back pain among universities, colleges and school teachers in Ethiopia, particularly in Gondar town. Methods: To assess prevalence of low back pain and associated factors among primary and secondary school, and higher institution (college and university) teachers in Gondar town, an institution based cross-sectional quantitative study was conducted. A total of 662 teachers were included in the study. Teachers in the town were selected by stratified random sampling from their institutions in which they work. Both bivariate and multivariate logistic regression techniques were used to identify factors associated with low back pain. Results: Of 602 teachers, 346 (57.5%) experienced low back pain (LBP) throughout their job career. The twelve month prevalence of LBP among teachers was 324 (53.8%). Doing regular physical exercise [AOR=0.52, 95%CI: 0.34, 0.82], provisions of office at working institution [AOR=0.52, 95%CI: 0.33, 0.81] and satisfaction with working environment and culture [AOR=0.55, 95%CI: 0.36, 0.86] were among factors significantly associated with low back pain. Conclusion: This study showed high prevalence of low back pain among teachers. Doing regular physical exercise, provisions of office at working institution and satisfaction with working environment and culture, were among the most contributing factors in reducing low back pain. Therefore, doing regular physical activity, avoiding their smoking habit, Getting enough time for sleep and avoiding worries reduces the risk of low back pain among teachers.
