title: Low discretionary time as a barrier to physical activity and intervention uptake.
abstract: OBJECTIVE
  To determine whether self-reported discretionary time was associated with physical activity and uptake of a physical activity promotion intervention in a multi-ethnic urban sample.
  
  
  METHODS
  We examined the association of self-reported discretionary time with hours/week of leisure-time physical activity at baseline and physical activity intervention uptake.
  
  
  RESULTS
  Low levels of discretionary time were significantly (P<0.01) associated with fewer hours/week (beta=-0.78, 95%CI=-1.34, -0.22) of physical activity at baseline. Discretionary time was not associated with physical activity intervention uptake.
  
  
  CONCLUSIONS
  Lack of discretionary time may serve as barrier to physical activity, but its importance on intervention uptake is less clear.
