Background: School teachers are among the occupational groups who are affected with low back pain. The Global Burden of Disease (GBD, 2010) estimated that low back pain is amongst the top ten disability-adjusted life years (DALYs) causing diseases and injuries. A systematic review studies suggested that the prevalence of low back pain among teaching staff ranges between 39% and 95%. Therefore, the aim of this study would be to assess the prevalence and associated factors of low back pain on school teachers in Mekelle City. Methods: Institution based cross-sectional study was conducted from March 5-April 30/2017. A total of 421 teachers were involved in the study. Simple random sampling technique was used to select respondents and all schools were included in the study. Results: The twelve month self-reported prevalence of low back pain among teachers was 223(54.9%). Female sex (AOR = 1.833, 95 % CI: 1.172, 2.868), smoking habit (AOR = 5.452, 95% CI: 1.774, 16.753), doing regular physical exercise (AOR = 0.486, 95 % CI: 0.309,0 .767), and sleep disturbance (AOR = 3.235, 95 % CI: 1.319, 7.931) were among factors which showed significance association with low back pain. Conclusion: This study has shown that prevalence of low back pain was high among school teachers. Being female, older age, smoking habit, no physical exercise, and sleep disturbance were the factors associated with low back pain. Hence, undertaking regular physical exercise, avoiding smoking habit and having enough time to sleep could minimize developing low back pain among teachers.
