Association Between Trouble Sleeping and Cataracts in U.S. Adults, 2005-2008

A 2005-2008 cross-sectional study of 2,601 U.S. adults aged 40 and older from the National Health and Nutrition Examination Survey (NHANES). The dataset, authored by Jun Huang and shared under a CC-BY-4.0 license, analyzes the association between self-reported trouble sleeping and cataract history. It was last updated on figshare in April 2026.

Use Cases

• Conducting secondary analysis on the sleep-cataract association based on the described logistic regression models.
• Examining subgroup interactions across demographic and clinical characteristics as mentioned in the results.
• Informing hypothesis generation for longitudinal studies on sleep interventions and cataract risk as suggested in the conclusion.

Strengths

• Dataset is derived from the authoritative National Health and Nutrition Examination Survey (NHANES).
• Analysis includes 2,601 adult participants and reports a specific odds ratio (OR=2.50) with confidence intervals.
• Models were adjusted for multiple covariates including sociodemographic factors, lifestyle variables, and comorbidities.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• Data is cross-sectional, preventing causal inference as noted in the description.
• The primary data file is a 48.0 KB DOC document, which may require format conversion for analysis.
