title: Panic attacks and panic disorder in a population-based sample of active Canadian military personnel.
abstract: BACKGROUND
  The factors contributing to psychiatric problems among military personnel, particularly for panic, are unclear. The objective of this study was to examine the prevalence and correlates of panic disorder and panic attacks in the Canadian military.
  
  
  METHODS
  Statistics Canada and the Department of National Defense conducted the Canadian Community Health Survey-Canadian Forces Supplement in 2002 (May to December) with a representative sample of active Canadian military personnel (aged 16-54 years; N = 8,441; response rate, 81.5%). Comparisons were made between respondents with no past-year panic attacks, panic attacks without panic disorder, and panic disorder on measures of DSM-IV mental disorders, as well as validated measures of disability, distress, suicidal ideation, perceived need for mental health treatment, and mental health service use. Lifetime exposure to combat operations, witnessing of atrocities, and deployments were also assessed.
  
  
  RESULTS
  Panic disorder and panic attacks were common in the military population, with past-year prevalence estimates of 1.8% and 7.0%, respectively. Both panic disorder and panic attacks were associated with increased odds of all mental disorders assessed, suicidal ideation, 2-week disability, and distress. Perceived need for mental health treatment and service use were common in individuals with panic attacks and panic disorder (perceived need: 46.3% for panic attacks, 89.6% for panic disorder; service use: 32.5% for panic attacks, 74.5% for panic disorder).
  
  
  CONCLUSIONS
  Panic attacks and panic disorder in the military are associated with outcomes that could be detrimental to well-being and work performance, and early detection of panic in this population could help reduce these negative outcomes.
