Association Between Sleep Trouble and Cataracts in US Adults, 2005-2008

United States adults aged 40 and older were analyzed for an association between self-reported trouble sleeping and cataract history. The dataset contains results from a cross-sectional study of 2,601 participants from the National Health and Nutrition Examination Survey (NHANES). The research was authored by Jun Huang and last updated on the platform in April 2026.

Use Cases

• Conducting secondary analysis of the sleep-cataract association based on the described logistic regression models.
• Replicating subgroup analyses across demographic and clinical characteristics as mentioned in the results.
• Designing longitudinal study protocols based on the causal mechanisms suggested in the conclusion.

Strengths

• Analysis is based on a nationally representative sample of 2,601 US adults.
• Results include a specific odds ratio (OR=2.50) with confidence intervals and p-value.
• Study adjusted for sociodemographic factors, lifestyle variables, and comorbidities.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a cross-sectional study, limiting causal inference as noted in the description.
