Association between sedentary behavior and low back pain; A systematic review and meta-analysis

Abstract

Background: Sedentariness is a substantial risk for many chronic diseases. We aimed to investigate the correlation of sedentary behavior and its indicators with low back pain (LBP) among adults and children. Methods: Original articles published up to April 28, 2020, using PubMed, Embase, Web of Science and Scopus were evaluated. Odds ratio (OR, 95% CI) was considered the overall effect size for desired associations. Results: We reviewed 49 English articles with analytical observational study design, of which, 27 studies with cross sectional/survey design were retained in the meta-analysis. Among adults, sedentary lifestyle was a considerable risk factor for LBP (OR = 1.24, 1.02-1.5); prolonged sitting time (OR = 1.42, 1.09-1.85) and driving time (OR = 2.03, 1.22-3.36) were the significant risk factors. Sedentary behavior was associated with LBP in office workers (OR = 1.23). Moreover, excess weight (OR = 1.35, 1.14-1.59) and smoking (OR = 1.28, 1.03-1.60) were associated with LBP. Among children, sedentary lifestyle was a remarkable risk factor for LBP (OR = 1.41, 1.24-1.60); prolonged TV watching (OR = 1.23, 1.08-1.41) and computer/mobile using and console playing time (OR = 1.63, 1.36-1.95) were significant risk factors for LBP. Consumption of coffee, however, has yield conflicting results to be considered as a risk factor. Moreover, the researches on the correlation between sedentariness and high-intensity LBP are scarce and inconclusive. Conclusion: Sedentary behavior, whether in work or leisure time, associates with a moderate increase in the risk of LBP in adults, children and adolescents.
