ObjectiveTo describe some sociodemographics and clinical characteristics of subjects with Non-specific Chronic Low Back Pain (NCLBP) in Primary Care, as well as to investigate their association with Fear-Avoidance (FA).DesignCross-sectional. Secondary analysis of an intervention study.LocationBasic Health Areas in Costa del Sol Health District (Málaga, Spain).ParticipantsAn analysis was performed on 147 subjects with NCLBP from a previous intervention study database in Primary Care Physiotherapy (PCP). Characteristics: age 18-65; understanding of the Spanish language; absence of cognitive disorders, fibromyalgia or dorsolumbar surgery, and to be able to perform physical exercise.Main MeasurementsThe main variable was FA level (FABQ and the FABQ-PA and FABQ-W) sub-scales. Clinical variables included: pain (NRPS-11), disability (RMQ), evolution, previous treatments and diagnostic imaging. The sociodemographic variables included: gender, age, educational level, and employment status.ResultsJust over half (51.7%) of the subjects had high FA on the FABQ-PA sub-scale. Sick leave (SL) [β=24.45 (P=.009*); β=13.03 (P=.016*); β=14.04 (P=.011*) for FABQ, FABQ-PA and FABQ-W, respectively]; primary studies level [β=15.09 (P=.01*); β=9.73 (P=.01*) for FABQ and FABQ-PA], and disability [β=1.45 (P<.001); β=0.61 (P<.001); β=0.68 (P<.001) for FABQ, FABQ-PA and FABQ-W, respectively] were associated with FA when they were modeled by multivariate regression.ConclusionsSome sociodemographic and clinical features of the NCLBP population are presented. Imaging tests (81.63%) and previous passive treatments (55.78%) could reflect problems of adherence to recommendations of CPGs. Sick leave, primary studies level, and disability were associated with FA. The findings should be interpreted in the light of possible limitations. Some suggestions for clinical practice are provided.Copyright © 2017 Elsevier España, S.L.U. All rights reserved.
