Vitamin D and Early Vascular Aging Study Data from Qingdao, 2023-2025

Data from a 2023-2025 cross-sectional study of 2,047 participants at the Health Management Center of the Affiliated Hospital of Qingdao University. The dataset likely contains measurements of serum 25-hydroxyvitamin D levels, brachial-ankle pulse wave velocity (baPWV), and demographic/health variables used to investigate the association between vitamin D and early vascular aging. The study was authored by Jinpeng Cong and shared on figshare under a CC-BY-4.0 license.

Use Cases

• Analyzing the nonlinear association between serum vitamin D levels and early vascular aging risk based on the identified 17.90 ng/mL threshold.
• Conducting subgroup analyses on the interaction between vitamin D and factors like sex, BMI, and age as described in the study results.
• Validating the logistic regression and restricted cubic spline models used to assess the odds ratio of early vascular aging.
• Investigating the prevalence of early vascular aging in a young and middle-aged adult cohort from a specific geographic region.

Strengths

• Includes data from 2,047 participants, providing a substantial sample size for analysis.
• Study design includes detailed subgroup analyses by age, sex, BMI, and other health factors.
• Results are based on specific statistical methods (logistic regression, restricted cubic splines) with reported odds ratios and confidence intervals.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• Data reflects a specific geographic and temporal context (Qingdao, 2023-2025), which may limit generalizability.
