Abstract

STUDY OBJECTIVES: To assess the prevalence of sleep problems and their association with psychotic symptoms using a global database. DESIGN: Community-based cross-sectional study. SETTING: Data were analyzed from the World Health Organization's World Health Survey (WHS), a population-based survey conducted in 70 countries between 2002 and 2004. PATIENTS OR PARTICIPANTS: 261,547 individuals aged ≥ 18 years from 56 countries. INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: The presence of psychotic symptoms in the past 12 months was established using 4 questions pertaining to positive symptoms from the psychosis screening module of the Composite International Diagnostic Interview. Sleep problems referred to severe or extreme sleep problems in the past 30 days. Multivariable logistic regression was used to estimate the associations. The overall prevalence of sleep problems was 7.6% and ranged from 1.6% (China) to 18.6% (Morocco). Sleep problems were associated with significantly higher odds for at least one psychotic symptom in the vast majority of countries. In the pooled sample, after adjusting for demographic factors, alcohol consumption, smoking, and chronic medical conditions, having sleep problems resulted in an odds ratio (OR) for at least one psychotic symptom of 2.41 (95% confidence interval [CI] 2.18-2.65). This OR was 1.59 (1.40-1.81) when further adjusted for anxiety and depression. CONCLUSIONS: A strong association between sleep problems and psychotic symptoms was observed globally. These results have clinical implications and serve as a basis for future studies to elucidate the causal association between psychotic symptoms and sleep problems.

  • A large WHO study combining data from 56 countries (n = 267,692) corroborates a cross-sectional relationship between sleep problems and several psychotic experiences.

    “More broadly, a large WHO study combining data from 56 countries (n = 267,692) corroborates a cross-sectional relationship between sleep problems (indexed by a single self-report questionnaire item based on insomnia criteria) and several psychotic experiences.”
  • Self-reported sleep disruption significantly increased the likelihood of concomitant psychotic experiences (OR = 2.26-2.84 across different psychotic experiences), even after controlling for anxiety and depression (remaining ORs of 1.54-1.68).

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.
