Background:
Obstructive sleep apnea (OSA) often goes undiagnosed, hindering timely intervention. This condition is associated with adverse cardiovascular and metabolic outcomes.
Objectives:
To investigate the prevalence of OSA in a large real-world U.S. sample, as well as night-to-night variability in OSA detection using home under-mattress sleep monitoring devices.
Methods:
We analyzed de-identified sleep and respiratory data from over 47 million nights recorded by the Sleeptracker-AI Monitor in 151,013 individual-years between September 1, 2021, and August 31, 2023. Individuals with at least 300 recorded nights in one of two one-year study periods (September to August) were included on the first year they met this criterion. Each one-year study period for each individual was analyzed, with mean AHI for the one-year period used to determine OSA categories.
Results:
A total of 12,400,521 recorded nights from 38,084 participants across the two one-year cohorts (17,516 men, 15,360 women, and 5208 undisclosed gender) were analyzed. OSA (AHI ≥5) prevalence [95 % CI] among individuals with normal BMIs (<25kg/m2) increased with age: women <50 years, 2.8 % [2.2 %, 3.5 %]; women ≥50 years, 16.1 % [14.6 %, 17.8 %] (OR: 6.8 [5.2, 8.7]); men <50 years, 11.2 % [9.7 %, 12.7 %]; and men ≥50 years, 37.5 % [34.8 %, 40.2 %] (OR: 4.8 [4.0, 5.7]). Moderate-to-severe and severe OSA subjects showed a ≥2-category severity reduction (moderate to normal or severe to mild/normal) on 5.1 ± 7.6 % and 5.3 ± 6.9 % of nights (mean ± SD), respectively. Maximum AHI values from 3 randomly selected nights demonstrated sensitivities/specificities [95 % CIs] of 95.2 % [94.2, 96.1]/94.4 % [94.2, 94.7] (moderate-to-severe OSA), and 95.6 % [93.7, 97.2]/98.0 % [97.9, 98.1] (severe OSA), categorized by mean AHI over 1 year.
Conclusion:
OSA prevalence increased with age in both genders, with higher rates in men and women≥ 50 years. Meanwhile, 5.1 % and 5.3 % of nights in moderate-to-severe and severe OSA cases had a 2-category lower OSA classification than their mean AHI category for that year.
