title: Knowledge on musculoskeletal diseases by the Spanish population.
abstract: OBJECTIVE
  To explore knowledge on musculoskeletal-diseases (MSDs) by the Spanish population.
  
  
  METHODS
  This was a cross-sectional study of the general population (> 18 years) using a telephone survey of 1,009 subjects stratified by habitat size, age, sex, and geographic area. A structured questionnaire was used to collect information on the subjects, their general knowledge of MSDs (GK), their specific knowledge of particular MSDs (SK), and their knowledge of their social impact (KSI). Synthetic indicators of the level of knowledge were used to analyze, using univariate and multivariate models, variables associated to the level of knowledge.
  
  
  RESULTS
  The KSI level ranges from medium-high (mean: 0.62 ± 0.16 out of 1), suggesting that most subjects recognize MSDs as disabling conditions which affect the ability to work and have a high personal and social cost. The GK level is intermediate (mean: 0.50 ± 0.17); 60% of subjects know something about MSDs, but 54% state that their information is poor/very poor. The SK level is low (mean: 0.18 ± 0.10), and there are some MSDs that are little known (lupus, spondylitis). Being male or retired or having a MSD is associated to a greater knowledge of MSDs.
  
  
  CONCLUSIONS
  The Spanish population has a medium level of knowledge of the frequency and extent to which MSDs affect performance of activities by those who suffer them. They identify them adequately and have a GK of their symptoms, but have little information about them. The level of knowledge varies depending on social and demographic factors and on whether or not the subject has direct or indirect experience of what a MSD means.
