title: Association between wearing a personal floatation device and death by drowning among recreational boaters: a matched cohort analysis of United States Coast Guard data.
abstract: OBJECTIVE
  To estimate the association between wearing a personal floatation device (PFD) and death by drowning among recreational boaters.
  
  
  METHODS
  Matched cohort study analysis of Coast Guard data.
  
  
  METHODS
  United States.
  
  
  METHODS
  Recreational boaters during 2000-2006.
  
  
  METHODS
  Risk ratio (RR) for drowning death comparing boaters wearing a PFD with boaters not wearing a PFD.
  
  
  RESULTS
  Approximately 4915 boater records from 1809 vessels may have been eligible for our study, but because of missing records and other problems, the analysis was restricted to 1597 boaters in 625 vessels with 878 drowning deaths. The adjusted RR was 0.51 (95% CI 0.35 to 0.74).
  
  
  CONCLUSIONS
  If the estimated association is causal, wearing a PFD may potentially prevent one in two drowning deaths among recreational boaters. However, this estimate may be biased because many vessels had to be excluded from the analysis.
