title: [Back pain and restricted daily physical activity in the Spanish adult population].
abstract: BACKGROUND
  Low back pain is a widespread health problem that affects a great part of the Spanish adult population; it also places a constraint on developing activities of daily living. The aim of this paper is to estimate the association between daily physical activity and chronic back pain in Spain.
  
  
  METHODS
  This paper analyses data from the European Health Survey in Spain 2009; it presents a cross sectional epidemiological study designed to assess the health of the Spanish population, in which 22,188 people participated (10,876 men and 11,312 women over 16 years ), representative of the total Spanish population. The variables studied are: back pain indicators obtained from the European Health Status Module and the European Health Care Module included in this survey, and the daily physical activity pattern obtained from the European Module of Health Determinants.
  
  
  RESULTS
  The total volume of daily physical activity is similar in healthy people and those who have back pain, but a pattern of low or moderate intensity in people with chronic back pain in the last twelve months (p <0.01) was observed with greater frequency.
  
  
  CONCLUSIONS
  People with chronic back pain do not show a lower volume of physical activity, but their physical activity pattern is often low or moderate. Developing a vigorous pattern of physical activity should be considered not only as a strategy to prevent this disease, but also as a therapeutic target in these patients.
