Also, LBP is a major occupational problem among nursing staff. The study aims to determine LBP, disability, quality of life (QoL), and the relationship between LBP and job-related risk factors and dimensions of QoL in nurses.<br> <strong>Materials and Methods:</strong> In this cross-sectional study with a descriptive-analytic approach, eligible nurses working in teaching hospitals affiliated with Mazandaran University of Medical Sciences were included in the study by census method. Data were collected based on the demographic questionnaire, Visual Analog Scale (VAS), Quebec Back Pain Disability Scale (QBPDS), and Short-Form 36 (SF-36) health survey questionnaire. Data were analyzed (descriptive, logistic regression, spearman correlation) using SPSS software, version 23.<br> <strong>Results: </strong>This study included 402 nurses with a mean age of 36.47&plusmn;7.1 years and employment mean of 11.83&plusmn;6.4 years of an employment. The prevalence of LBP was 86.3% and the mean of pain intensity and disability were 4.8&plusmn;2.7 and 30.4&plusmn;17.4, respectively. The mean QoL components, such as physical and mental were 58.03&plusmn;19.6 and 57.42&plusmn;18.3, respectively. The factors that were significantly associated with LBP were body mass index (BMI) (P<0.0001), frequent bending (P=0.004), and workplace communication (P=0.008). LBP affected dimensions of QoL, especially physical function (P=0.008), role physical (P=0.02), general health (P<0.0001), and social function (P=0.03).<br> <strong>Conclusion: </strong>This study showed the high prevalence of LBP among nurses and the role of individual and workplace factors in the occurrence of LBP. Such cognition facilitates the design of an educational program and undertakes the targeted preventive actions.</span></span><br> &nbsp; Nurse, Low back pain, Disability, Quality of life (QoL) 59 66 http://jhs.mazums.ac.ir/browse.php?a_code=A-10-816-2&slc_lang=en&sid=1 Seyedeh-Somayeh Kazemi سیده سمیه کاظمی somayeh.kazemi7@gmail.com 10031947532846009514 10031947532846009514 Yes Department of Public Health, School of Health, Mazandaran University of Medical Sciences, Sari, Iran. گروه بهداشت عمومی، دانشکده بهداشت، دانشگاه علوم پزشکی مازندران، ساری، ایران.
