title: Knowledge on health and back care education related to physical activity and exercise in adolescents.
abstract: OBJECTIVE
  The aim of this study was to analyze the relationship between the specific level of knowledge on health and back care-related physical activity practice and exercise with low back pain (LBP) in adolescents.
  
  
  METHODS
  This is a cross-sectional study. The sample consisted of a total of 576 adolescents aged 13-18 years (mean age 15.5, SD 1.4). Self-reported questionnaires were used to record specific knowledge on health and back care and LBP in healthy adolescents.
  
  
  RESULTS
  The prevalence of LBP was 46.3% [95% confidence interval (CI) 44.9-47.8]. Students with LBP scored slightly higher than non-sufferers, getting non-significant values. The level of specific knowledge increased with age (F = 7.308; p = 0.002). Stepwise logistic regression analysis showed that older girls group (>16 years old) was significantly associated with LBP odds ratio (OR) 2.9 (95% CI 1.77-4.74; p = 0.000).
  
  
  CONCLUSIONS
  High school students have a low level of specific knowledge. Back care education in the school curriculum is recommended.
