Abstract

BACKGROUND: Limited data have suggested that sleep-disordered breathing, a condition of repeated episodes of apnea and hypopnea during sleep, is prevalent among adults. Data from the Wisconsin Sleep Cohort Study, a longitudinal study of the natural history of cardiopulmonary disorders of sleep, were used to estimate the prevalence of undiagnosed sleep-disordered breathing among adults and address its importance to the public health. METHODS: A random sample of 602 employed men and women 30 to 60 years old were studied by overnight polysomnography to determine the frequency of episodes of apnea and hypopnea per hour of sleep (the apnea-hypopnea score). We measured the age- and sex-specific prevalence of sleep-disordered breathing in this group using three cutoff points for the apnea-hypopnea score (> or = 5, > or = 10, and > or = 15); we used logistic regression to investigate risk factors. RESULTS: The estimated prevalence of sleep-disordered breathing, defined as an apnea-hypopnea score of 5 or higher, was 9 percent for women and 24 percent for men. We estimated that 2 percent of women and 4 percent of men in the middle-aged work force meet the minimal diagnostic criteria for the sleep apnea syndrome (an apnea-hypopnea score of 5 or higher and daytime hypersomnolence). Male sex and obesity were strongly associated with the presence of sleep-disordered breathing. Habitual snorers, both men and women, tended to have a higher prevalence of apnea-hypopnea scores of 15 or higher. CONCLUSIONS: The prevalence of undiagnosed sleep-disordered breathing is high among men and is much higher than previously suspected among women. Undiagnosed sleep-disordered breathing is associated with daytime hypersomnolence.

  • The Wisconsin Sleep Cohort and SHHS found a general prevalence of 24% in men and 9% in women using the alternative hypopnea definition of ≥4% oxygen desaturation.

    “These studies found a general prevalence of 24% in men, 9% in women using the alternative definition of hypopnea (≥4% oxygen desaturation).”

    From International Consensus Statement on Obstructive Sleep Apnea (2023) · cites this paper as [90]

    The Occurrence of Hypersomnolence (p. 3) gives prevalence estimates of 24% for men and 9% for women with an apnea-hypopnea score of at least 5. Interpretation of Polysomnographic Data (p. 2) defines hypopnea using a decrease of at least 4% in oxyhemoglobin saturation. These are estimates for middle-aged adults from the Wisconsin Sleep Cohort; this paper does not report an SHHS finding or establish prevalence for the general population. (LLM, conf=0.87)

  • A smaller subset, 3%-7% in men and 2%-5% in women, had OSAS based on AHI ≥5 with excessive daytime sleepiness.

    “A smaller subset, 3%–7% in men and 2%–5% in women, had OSAS based on AHI ≥ 5 with excessive daytime sleepiness.88,90,92”

    From International Consensus Statement on Obstructive Sleep Apnea (2023) · cites this paper as [90]

    The Occurrence of Hypersomnolence section (p. 3) estimates that 4% of men and 2% of women had both an apnea-hypopnea score of at least 5 and self-reported hypersomnolence. The paper supports the criterion and estimates within the quoted ranges, but it does not report the ranges of 3%–7% for men and 2%–5% for women. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • An increase in BMI by 1 standard deviation was associated with a threefold increase in risk of OSA.

    “Another study showed an increase in BMI by 1 standard deviation (SD) was associated with a threefold increase in risk of OSA.90”

    From International Consensus Statement on Obstructive Sleep Apnea (2023) · cites this paper as [90]

    The Risk Factors discussion (p. 5) describes a threefold increase for a one-SD increment in any measure of body habitus. But Table 5 (p. 5) gives the BMI-specific odds ratio as 4.17, not threefold, for sleep-disordered breathing defined by an apnea-hypopnea score of at least 5. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • OSA is a heterogeneous disorder with different pathways to disease.

    “There are different pathways to disease, such that OSA is a heterogeneous disorder.”

    From International Consensus Statement on Obstructive Sleep Apnea (2023) · cites this paper as [90]

    The Discussion (p. 4) describes a wide spectrum of sleep-disordered breathing severity, and Risk Factors (p. 5) identifies sex and obesity as risk factors. These findings support variation in the disorder, but the paper does not establish different pathways to disease. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Men are more likely than women to report snoring (34% vs. 19%).

    “Sex differences in reported sleep symptoms have been reported, with men being more likely to report snoring (34% vs. 19%) and women being more likely to report hypersomnolence (22.6% vs. 15.5%).90”

    From International Consensus Statement on Obstructive Sleep Apnea (2023) · cites this paper as [90]

    Table 1 (Collection of Polysomnographic Data, p. 2) supports the direction of the sex difference: 44% of men and 28% of women were classified as habitual snorers. It does not support the attributed 34% versus 19% figures; its definition of habitual snoring also includes reported snorting or breathing pauses. (LLM, conf=0.87)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
