Introduction: Low back pain (LBP)can cause greater disability and can reduce the quality of life (QoL).  LBP affects all the people from children to older group.LBP is a disabling disease which restricts the QoL. Aim:To assess the QoL among patients with LBP. Material and methods:The cross–sectional descriptive design was adopted. Using non–probability convenience sampling technique, 120 patients with LBP were recruited from Out Patient Department(OPD), Sri Ramachandra Hospital(SRH), Chennai.A structuredinterview was conducted with the tool, SF–36 to obtain the data on QoL. Results: The results of the study depicted that 79.2% patients had poor QoL. The data on dimensions of QoL depicted that higher mean percentage score was noted in the mental health aspect (51.50%) and the body pain dimension had a low mean percentage score (29.78%). The mean percentage of composite summaries of QoL was low: physical (43.18), mental (47.10) and global (44.43) indicating a low QoL in all its spheres.A statistically significant association was noted between the mean score of QoL and type of exercise at p < .05. Conclusion: The present study makes evident that majority of the patients with LBP suffers poor QoL and LBP affects all dimensions of QoL.
