The research aimed to evaluate the influence of pain on quality of life (QoL), and quality of sleep (QoS) in patients suffering from chronic low back pain, during 2 years of follow-up. The study included 128 patients. Patients were tested on 4 occasions (on admission, after 6, 12, and 24 months from initial testing). Based on age, they were divided into 3 groups: I group 18 to 30 years; II group 30 to 50 years; III group 50 to 65 years. The SF36 QoL questionnaire, Pittsburgh sleep quality index (PSQI), and the Hamilton scales for the assessment of anxiety (HARS) and depression (HDRS) were used. We did not find any statistically significant correlation between worse QoL and QoS with patients\u2019 epidemiological factors, but younger patients tend to have slightly worse scores. Elderly patients were more disabled (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2005&lt;.01). In young individuals, SF36 scores were significantly higher (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2005&lt;.05), and PSQI scores were lower (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2005&lt;.01) than in the elderly. Neuropathic pain was an independent predictor of the lower SF36 scores \u2013 which indicates worse QoL (adjusted R\n                    <jats:sup>2<\/jats:sup>\n                    \u2005=\u20050.73,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2005&lt;.01 for the overall model) and higher PSQI scores \u2013 which indicates worse QoS (adjusted R\n                    <jats:sup>2<\/jats:sup>\n                    \u2005=\u20050.71,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2005&lt;.01 for the overall model). Neuropathic pain is a predictor of worse QoL and QoS. During the follow-up reduction in pain is noticed in all groups, but more pronounced in patients younger than 50.\n
