title: The association of perceived and objectively measured crime with physical activity: a cross-sectional analysis.
abstract: BACKGROUND
  Crime is one aspect of the environment that can act as a barrier to physical activity. The goals of this study were to (1) compare measures of perceived crime with observed crime and (2) examine the association between the independent and combined effects of objective and perceived crime on physical activity.
  
  
  METHODS
  Perceived crime and physical activity were assessed in 1659 persons via telephone survey. Crime was objectively measured in a subset of 303 survey participants.
  
  
  RESULTS
  For all types of crime, there was low agreement between objective and perceived measures. Both perceived and objectively measured crime were independently associated with leisure activities.
  
  
  CONCLUSIONS
  This study suggests that perceptions and objective measures of crime are both important correlates of leisure physical activity. Evaluating both measures is necessary when examining the relationship between crime and physical activity to develop interventions that will most influence leisure physical activity levels.
