BackgroundLow back pain (LBP) is the most common musculoskeletal disorder affecting the general population and it is believed to be associated with depression.ObjectiveThe study aim was to describe and compare the impact in a sample of people with subacute LBP (SLBP) and patients without LBP with normalized reference values in the light of the scores obtained with regard using the Beck Depression Inventory (BDI).Study DesignThis was a case-control study.SettingsPhysiotherapist area at a care center.MethodsA sample of 164 participants of a mean age of 41.45 ± 0.97 came to a physical therapy clinic where self-reported data were registered, informants' professional activity was determined, and the scores obtained were compared in the BDI.ResultsTotal BDI scores at SLBP and their controls were 21.52 ± 6.93 (11 - 43) and 17.30 ± 5.09 (11 - 30), respectively (P < 0.001). The SLBP patient has 2.12 times more likely to have moderate depression (OR 2.12 (1.07 - 4.18) and 18.82 times more likely to have serious depression (OR 18.82 (1.06 - 331.81) compared to their controls (P < 0.05).LimitationsThe study was not a randomized controlled trial. Although primary outcome data were self-reported, the assessor was not blinded.ConclusionsPeople with SLBP also have a significant increase in depression based on BDI scores, regardless of gender.
