Perimenopausal Women Clinical Data on Insomnia, Hormones, and Amino Acids

Shizhuo Yang's cross-sectional study includes data from 187 perimenopausal women aged 45–55 years. The dataset contains clinical assessments for insomnia, anxiety, and depression severity, alongside measured serum levels of amino acids and hormones like prolactin and tryptophan. It was last updated on May 1, 2026.

Use Cases

• Analyzing the association between serum prolactin levels and insomnia severity based on Insomnia Severity Index scores.
• Investigating the moderating role of tryptophan on the relationship between prolactin and insomnia as described in the moderation analysis.
• Exploring correlations between hormone/amino acid levels and co-occurring anxiety and depression using GAD-7 and PHQ-9 scores.

Strengths

• Includes data from 187 perimenopausal women, a defined clinical cohort.
• Contains multiple validated clinical assessment scores (ISI, GAD-7, PHQ-9) alongside biochemical measurements.
• The study design and analysis methods, including moderation analysis, are clearly described.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data file is a DOCX document (88.8 KB), suggesting the primary data may be embedded in tables or text rather than a dedicated structured format.
