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

2,601 adults aged 40 and older from the U.S. National Health and Nutrition Examination Survey (NHANES) 2005-2008 cycles. This cross-sectional study by Jun Huang investigates the link between self-reported trouble sleeping and cataract surgery history, finding a significant adjusted odds ratio of 2.50. The dataset was last updated on figshare in April 2026.

Use Cases

• Assessing the association between sleep disorders and cataract risk based on self-reported health data.
• Conducting subgroup analyses of demographic and clinical characteristics mentioned in the study.
• Replicating or validating the logistic regression models adjusted for sociodemographic factors, lifestyle, and comorbidities.
• Informing public health strategies for cataract prevention that incorporate sleep health considerations.

Strengths

• Data is sourced from the authoritative, nationally representative NHANES survey.
• Analysis includes a specific sample size of 2,601 adults and reports a statistically significant odds ratio (OR=2.50).
• Study design adjusts for multiple covariates including sociodemographic factors, lifestyle variables, and comorbidities.

Limitations

• Row count and column-level documentation for the underlying data are unknown, requiring manual inspection after download.
• The cross-sectional design limits causal inference, as noted by the author.
• Data relies on self-reported measures for both sleep trouble and cataract status, which may introduce bias.
