摘要

目的：糖尿病视网膜病变（DR）是糖尿病常见的微血管并发症，与痴呆风险增加有关。本研究旨在开发机器学习（ML）模型来预测DR的发生，并评估其作为痴呆症预后生物标志物的潜力。方法：我们纳入27,929例年龄 ≥ 50 岁的新诊断为2型糖尿病且既往无痴呆或眼病的患者。使用三种ML算法开发了一年内DR的预测模型：极端梯度增强（XGBoost），随机森林和最小绝对收缩和选择算子。表现最好的模型在8个机构中进行了外部验证。研究人员对患者进行了为期三年的随访，以评估痴呆症的发病率。使用Kaplan-Meier和Cox回归比较ml预测的DR组和非DR组的痴呆风险，并通过荟萃分析汇总结果。结果：XGBoost效果最佳（AUROC: 0.746），外部验证AUROC范围为0.555 ~ 0.620。预测DR与全因痴呆风险增加（HR: 1.32, 95%可信区间[CI] 1.12-1.56）、阿尔茨海默病（HR: 1.30, 95% CI 1.07-1.58）和血管性痴呆（HR: 1.38, 95% CI 1.12-1.69）显著相关。结论：ml预测的DR与未来痴呆显著相关，突出了其在糖尿病患者早期风险分层中的价值。

Prediction of diabetic retinopathy using machine learning and its association with dementia risk in older adults with type 2 diabetes mellitus

Aims

Diabetic Retinopathy (DR), a common microvascular complication of diabetes, has been associated with an increased risk of dementia. This study aimed to develop Machine Learning (ML) models to predict DR occurrence and evaluate its potential as a prognostic biomarker for dementia.

Methods

We included 27,929 patients aged ≥ 50 years newly diagnosed with type 2 diabetes mellitus without prior dementia or eye disease. Prediction models for DR within one year were developed using three ML algorithms: extreme gradient boosting (XGBoost), random forest, and least absolute shrinkage and selection operator. The best-performing model was externally validated across eight institutions. Patients were followed for three years to assess dementia incidence. Dementia risk between ML-predicted DR and non-DR groups was compared using Kaplan-Meier and Cox regression, with results pooled via meta-analysis.

Results

XGBoost demonstrated the best performance (AUROC: 0.746), with external validation AUROCs ranging from 0.555 to 0.620. Predicted DR was significantly associated with increased all-cause dementia risk (HR: 1.32, 95% confidence interval [CI] 1.12–1.56), Alzheimer’s disease (HR: 1.30, 95% CI 1.07–1.58), and vascular dementia (HR: 1.38, 95% CI 1.12–1.69).

Conclusions

ML-predicted DR was significantly associated with future dementia, highlighting its value in early risk stratification among patients with diabetes.
