title: Trends in leisure time and work-related physical activity in the Spanish working population, 1987-2006.
abstract: OBJECTIVE
  To analyze time trends in the prevalence of leisure time (LTPA) and work-related (WRPA) physical activity between 1987 and 2006 in the Spanish working population.
  
  
  METHODS
  We analyzed data taken from the Spanish National Health Surveys for 1987 (n = 29,647), 1993 (n = 20,707), 1995-1997 (n = 12,800), 2001 (n = 21,058), 2003 (n = 21,650), and 2006 (n = 29,478). The main variables were LTPA and WRPA in working adults aged 18-64 years old. We analyzed sociodemographic characteristics, self-perceived health status, lifestyle habits and associated comorbidities using multivariate logistic regression models.
  
  
  RESULTS
  The prevalences of LTPA and WRPA were lower in women than in men (p < 0.05). The practice of LTPA (OR: 1.54, 95%CI: 1.32-1.80 for women; OR = 1.15, 95%CI: 1.02-1.31 for men) and WRPA (OR = 1.73, 95%CI: 1.38-2.19 for women; OR = 1.55, 95%CI: 1.44-1.91 for men) significantly increased from 1987 to 2006. In both genders, the variables associated with a higher likelihood of practicing LTPA were greater age, higher educational level and being an ex- or non-smoker, while negative predictors included being married, worse self-perceived health, and obesity. Factors that increased the probability of reporting WRPA were being married, worse self-rated health status, and sleeping > 8h per day. The only factor that reduced the probability of reporting WRPA was being an ex- or non-smoker.
  
  
  CONCLUSIONS
  We found an increase in LTPA and WRPA in the last 20 years in the Spanish working population. Several factors were associated with a higher or lower likelihood of practicing LTPA or WRPA in this population.
