HbA1c Trends in Pediatric Type 1 Diabetes Patients in Taiwan, 2000-2023

688 patients with type 1 diabetes from two hospitals in Taiwan were analyzed over a 23-year period from 2000 to 2023. The dataset contains repeated measures of HbA1c levels and achievement rates for optimal glycemic control. Author Jung Chou published the study on figshare under a CC-BY-4.0 license.

Use Cases

• Analyze secular trends in HbA1c levels based on repeated measurements over 23 years.
• Model the impact of sociodemographic factors like sex, DKA status, and age at diagnosis on glycemic control.
• Evaluate the achievement rate of optimal HbA1c levels (<7.0%) over time.
• Train predictive models for glycemic outcomes using patient characteristics and calendar year.

Strengths

• Data spans 23 years (2000-2023), providing a long-term longitudinal perspective.
• Analysis includes 688 patients with repeated measures, allowing for individual trend tracking.
• Study uses advanced statistical models (linear mixed-effects, GEE) to adjust for covariates and test interactions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is limited to two hospitals in Taiwan, which may reflect geographic bias.
