Participant Characteristics Based on Early Vascular Aging Status in a Chinese Cohort

2047 participants from a health management center in China were examined between May 2023 and May 2025. The dataset, shared by Jinpeng Cong, compares characteristics between an Early Vascular Aging group (687 individuals) and a control group (1360 individuals). It was used to analyze the association between serum vitamin D levels and vascular aging risk.

Use Cases

• Assessing the association between serum 25-hydroxyvitamin D levels and early vascular aging risk based on brachial-ankle pulse wave velocity.
• Conducting subgroup analyses for factors like sex, BMI, and age mentioned in the study description.
• Identifying threshold effects in biological markers, such as the 17.90 ng/mL inflection point for vitamin D described in the results.
• Comparing demographic and health characteristics between groups with and without early vascular aging.

Strengths

• Dataset includes 2047 participants, providing a substantial sample size for analysis.
• Clear group definitions with 687 individuals in the EVA group and 1360 in the control group.
• Study design includes subgroup analyses by multiple factors like age, sex, BMI, and smoking status.

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 may reflect geographic bias inherent to a single health management center in China.
