The following are key points to remember from this American Heart Association Scientific Statement about sleep duration and quality and its impact on lifestyle behaviors and cardiometabolic health:
- Currently, 50-70 million Americans suffer from a sleep disorder or report insufficient sleep.
- The two most common conditions are insomnia, likely present in 5-15% of the population, and obstructive sleep apnea (OSA), estimated in 10% of men and 3% of women <50 years of age.
- Based on epidemiological data, both short sleep duration (<7 hours per night) and long sleep duration (>9 hours per night) disorders as well as OSA and insomnia are associated with poor cardiometabolic risk and outcomes.
- In general, compared to patients with normal sleep duration, sleep restriction studies report increased caloric intake.
- Data do not support major changes in energy expenditure in short duration sleep disorder, due to the multiple factors contributing to total energy expenditure.
- Overall, it is not clear whether treating sleep disorders has a positive impact on risk of obesity.
- The best evidence for lowering cardiovascular risk among populations with sleep-disordered breathing comes from improvement in blood pressure.
- Future observational and clinical studies will need longer follow-up and more detailed measurement of sleep architecture and behavior.
- Look for brief sleep behavior tools and intervention strategies to be used by busy clinicians in the future.
