Hospitalized Latent Autoimmune Diabetes in Adults (LADA) patients in Southwest China face 47.4% hypoglycemia risk, linked to insulin pump use and glycemic excursions.
Background
Latent Autoimmune Diabetes in Adults (LADA) is a form of diabetes characterized by progressive β-cell dysfunction and significant glycemic lability, which inherently increases the risk of hypoglycemia, especially in a hospital setting. Despite this known susceptibility, comprehensive real-world data on the epidemiology and specific risk factors for in-hospital hypoglycemia among LADA patients remain scarce. This gap is particularly pronounced in diverse multiethnic populations, such as those found in Southwest China, hindering the development of targeted prevention strategies.
Study Design
Researchers conducted a multicenter retrospective cohort study, enrolling 709 hospitalized patients with LADA from five tertiary hospitals across Southwest China. Data were collected from January 2019 to September 2025, following STROBE guidelines. Missing data were handled using multiple imputation by chained equations. Univariate logistic regression was used for initial factor screening, followed by multivariate logistic regression to identify independent associated factors. Model performance was evaluated using AUC for discrimination and Nagelkerke's R2 for goodness of fit, with sensitivity analyses ensuring robustness.
Results
The study identified a high overall in-hospital hypoglycemia incidence of 47.39% among LADA patients, with notable regional variations across Southwest China. After pooling results from 20 imputed datasets, seven factors were independently associated with hypoglycemia risk. The strongest predictor was insulin pump therapy, increasing risk by over eight-fold:
Insulin pump therapy was associated with an OR = 8.233 (95% CI: 3.914-17.274). Other significant factors included the largest amplitude of glycemic excursions (OR = 1.136, 95% CI: 1.081-1.193), length of hospital stay (OR = 1.134, 95% CI: 1.074-1.197), and a prior history of hypoglycemia (OR = 2.447, 95% CI: 1.448-4.024). Sex (OR = 1.655, 95% CI: 1.065-2.574) and geographic origin (OR = 0.369, 95% CI: 0.225-0.605) also played roles, alongside glycated hemoglobin (OR = 0.902, 95% CI: 0.837-0.973), where lower
HbA1cwas associated with higher risk. The final model demonstrated satisfactory discriminative ability and calibration.
Key Findings
- In-hospital hypoglycemia incidence among LADA patients was 47.39%.
- Insulin pump therapy increased hypoglycemia risk by 8.233 times (OR = 8.233).
- Largest amplitude of glycemic excursions raised risk by 13.6% per unit increase (OR = 1.136).
- Prior hypoglycemia history increased risk by 2.447 times (OR = 2.447).
- Lower glycated hemoglobin (
HbA1c) was associated with increased hypoglycemia risk (OR = 0.902).
Why It Matters
This study highlights the substantial burden of in-hospital hypoglycemia in LADA patients, emphasizing the need for enhanced vigilance and proactive management. Clinicians should prioritize intensive monitoring and personalized insulin titration for LADA patients on insulin pump therapy, those with a history of hypoglycemia, and individuals exhibiting high glycemic variability. The findings underscore the importance of considering patient-specific factors, including sex and geographic origin, in risk stratification. While this provides crucial insights for inpatient care, further prospective studies are needed to validate these risk factors and develop predictive models for real-time clinical application, moving towards more precise hypoglycemia prevention protocols.
