From the abstract:
Context: Sleep disorders often remain undiagnosed. Untreated sleep disorders among police officers may adversely affect their health and safety and pose a risk to the public.
Objective: To quantify associations between sleep disorder risk and self-reported health, safety, and performance outcomes in police officers.
Conclusion: Among a group of North American police officers, sleep disorders were common and were significantly associated with increased risk of self-reported adverse health, performance, and safety outcomes.
