Vitamin D Status and Fracture Site Associations in 2,543 Elderly Patients

A cross-sectional analysis of 2,543 hospitalized patients aged 60 years and older with fragility fractures. The dataset, authored by Weifeng Lv and last updated in April 2026, measures serum 25(OH)D concentrations and analyzes associations with demographic factors, comorbidities, and specific fracture sites.

Use Cases

• Modeling risk factors for vitamin D deficiency based on age, sex, season, and medical history.
• Analyzing differences in vitamin D levels across specific fracture sites like hip, vertebral, and multiple fractures.
• Investigating the prevalence of vitamin D deficiency and insufficiency within a hospitalized elderly population.

Strengths

• Includes 2,543 patient records, providing a substantial sample size for analysis.
• Reports specific prevalence statistics: 35.9% deficient, 44.2% insufficient, and 19.9% sufficient.
• Contains detailed clinical measurements, including median serum 25(OH)D concentration of 22.60 ng/mL.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown for the underlying data table, which may limit suitability assessment.
• Data may reflect geographic or hospital-specific bias inherent to the single-study source.
