Probability of Having Obstructive Sleep Apnea
12% (up to 30% in men)
Lifetime probability in US
About 12% of all US adults have obstructive sleep apnea, with up to 80% of moderate-to-severe cases undiagnosed.
Obstructive sleep apnea (OSA) affects an estimated 30 million Americans (about 12% of adults), with significantly higher rates in men (about 25-30%) compared to women (about 9-17%). Up to 80% of moderate-to-severe cases remain undiagnosed, making it one of the most underrecognized health conditions.
Risk factors include obesity (the strongest modifiable risk factor; a 10% weight gain increases OSA risk 6-fold), male sex, age over 40, large neck circumference (>17 inches for men, >16 inches for women), family history, alcohol use, smoking, and nasal congestion. Anatomical factors like a recessed jaw, enlarged tonsils, and a thick tongue also contribute.
Untreated OSA significantly increases the risk of hypertension (2-3x), heart attack (3x), stroke (4x), atrial fibrillation, type 2 diabetes, motor vehicle accidents (2-7x), and depression. Treatment with continuous positive airway pressure (CPAP) is the gold standard and reduces cardiovascular risk and improves quality of life. Alternatives include oral appliances, positional therapy, weight loss (which can cure mild OSA), and surgical options like uvulopalatopharyngoplasty (UPPP) or hypoglossal nerve stimulation (Inspire).
