Background: Low back pain (LBP) as a musculoskeletal disorder is one of the most common occupational injuries\nin nurses but there isnââ?¬â?¢t any valid measure of the prevalence of LBP in Iranian nursing. In order to increase the\npower and improve the estimates of the prevalence of LBP in Iranian nurses, a comprehensive meta-analysis was\ncarried out. A summary measure of all studies conducted in this field was found and distributions of LBP were\nevaluated based on different variables.\nMethods: Inclusion criteria included articles with prevalence of LBP in Iranian nurses, who had at least six months\nof work experience without any trauma, injuries to spine, or any underlying disease. The keywordsââ?¬Å?prevalence, low\nback pain, nursesââ?¬Â, and ââ?¬Å?Iranââ?¬Â were used as part of this search. Databases such as Pubmed, Web of Science, Science\ndirect, Scopus, IranMedex, Irandoc, Magiran, SID, CIVILICA, IMEMR and Google scholar were searched up to and\nincluding 15 June 2016. For data extraction a form was designed that included the following variables: Author\nnames, province, sample size, age, gender, marital status, work experience, body mass index, job type, smoking\nstatus, work schedule, year of publication, type of standard questionnaire, prevalence of LBP, studiesââ?¬â?¢ quality score\nand climate classifications. Data analysis was carried out using fixed and random effects model. Heterogeneity\nbetween studies was assessed by using the I2 and Q tests.\nResults: In all 1250 articles were identified and 22 articles with 9347 participants met the inclusion criteria for metaanalyses\nafter filtering. The prevalence of low back pain during their working life and during the last year, was\nestimated at 63% (95% Confidence Interval (CI): 57.4ââ?¬â??68.5) and 61.2% (95% CI: 55.7ââ?¬â??66.7) respectively. The\nprevalence rate of this disorder was 58.7% (95% CI: 35.8ââ?¬â??81.7) and 60.4% (95% CI: 52.2ââ?¬â??68.6) among men and\nwomen respectively. Furthermore, prevalenceââ?¬â?¢s of LBP were 59.5% in wards nurses, 50.3% in operating room\ntechnicians, and 39.4% in aid nurses.\nConclusions: The results showed the high prevalence of LBP injury in nurses, especially female nurses. The effect of\nmusculoskeletal disorders such as LBP may be reduced by considering proper observation of the principles of\nergonomics in the workplace, performing physical examinations on a regular basis, identifying risk factors in the\nadvancement of musculoskeletal disorders and then trying to fix them.
