Abstract

Objective Establish the association between insomnia and various physical and mental health symptoms as well as objective measures of sleep disturbance while controlling for age, gender and BMI in a large random sample of the general public.Methods A subsample (N=1741) was selected for a single-night sleep laboratory evaluation from a larger random sample (N=16,583) of the general public (20-100 years old).Results The prevalence of insomnia was 7.5% and difficulty sleeping an additional 22.4%. The complaints were more frequent in women and in non-Caucasian minorities. A multivariate logistic regression analysis indicated that depression was the single strongest factor followed by female gender associated with either insomnia or difficulty sleeping. Minority status and a history of colitis, hypertension and anemia were also associated, but to a lesser degree. The final model did not include age, BMI as well as any of the sleep laboratory findings.Conclusion These findings support the conclusion that mental health variables have the primary independent association with a complaint of insomnia. Other factors including minorities and hypertension are also independently associated, though to a lesser degree. Other primary sleep disorders, e.g., sleep apnea, do not seem to play a major role in insomnia. These findings underscore the fact that insomnia is a symptom associated with a wide variety of mental and physical health problems requiring a proper psychiatric and medical management.

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.
