Serum Vitamin D and Islet Function in Postmenopausal Women with Diabetes and Osteoporosis

A clinical study of 343 consecutively hospitalized postmenopausal women with type 2 diabetes and osteoporosis between December 2024 and December 2025. The dataset, authored by Xiuping Yin and shared on figshare, analyzes associations between serum 25-hydroxyvitamin D levels and islet function, bone mineral density, and insulin resistance.

Use Cases

• Analyze the correlation between vitamin D levels and insulin resistance based on HOMA-IR values.
• Investigate the relationship between vitamin D sufficiency and bone mineral density based on T-scores.
• Model β-cell function based on HOMA-β and its association with serum 25(OH)D levels.
• Compare clinical characteristics like BMI and HbA1c across groups with different vitamin D statuses.

Strengths

• Dataset includes 343 patient records.
• Analysis includes multivariable linear regression adjusting for age, BMI, HbA1c, and T2DM duration.
• Data is licensed under CC-BY-4.0 for open reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small at 71.4 KB, indicating limited scope.
