TY - JOUR T1 - PRevalence of low back pain and its effect on health-related quality of life in adolescents AU - Pellisé F, Balagué F, Rajmil L, et al Y1 - 2009/01/05 N1 - 10.1001/archpediatrics.2008.512 JO - Archives of Pediatrics & Adolescent Medicine SP - 65 EP - 71 VL - 163 IS - 1 N2 - Objectives  To assess the prevalence of low back pain (LBP) in adolescents and the clinical features of LBP in 2 European countries and to evaluate the effect of LBP on health-related quality of life (HRQOL) using standardized validated generic and disease-specific instruments.Design  Cross-sectional study.Setting  Secondary schools of Barcelona, Spain, and Fribourg, Switzerland.Participants  Representative sample of adolescents from the 2 cities.Intervention  Selected adolescents completed a questionnaire including a generic HRQOL (KIDSCREEN-52) and 2 LBP-specific instruments.Main Outcome Measures  Results of KIDSCREEN-52, the Roland-Morris Disability Questionnaire, and the Hanover Functional Ability Questionnaire.Results  A total of 1470 adolescents (52.6% male) with a mean (SD) age of 15.05 (1.17) years completed the questionnaires (response rate, 85.1%). Low back pain was reported by 587 adolescents (39.8%): isolated LBP in 250 (42.6%), LBP plus other pain in 271(46.2%), LBP plus whole-body pain in 50 (8.5%, and unclassifiable LBP in 16 (2.7%). Five hundred adolescents (34.7%) reported no pain, and 369 (25.6%) reported other pain without LBP. In those with isolated LBP, the percentage of adolescent boys was higher (54.6%; P < .001) and the LBP was mildest. In those with LBP plus whole-body pain, the percentage of adolescent girls was higher (62%; P < .001) and LBP was most severe. All KIDSCREEN scores in the group with LBP plus whole-body pain were significantly lower than in the other groups (effect size, 0.52-1.24). No differences were found between the groups who reported isolated pain, no pain, or other pain with no LBP. On the LBP-specific instruments, adolescents who reported LBP plus other pain had significantly poorer scores (P < .001) compared with those with isolated LBP but better scores (P < .001) than those with LBP plus whole-body pain.Conclusions  Low back pain in adolescents is a prevalent symptom with overall low associated disability and little effect on health-related quality of life. A subset of adolescents in whom LBP is associated with whole-body pain report significant impairment and deserve more attention.
