Summary

Many people develop type 2 diabetes years after their first health check. This research used data that people in Qatar had already given in routine health checks, such as bone scans and eye photographs, to predict who is likely to develop diabetes years ahead.

Using longitudinal data from Qatar Biobank, this doctoral research linked each participant’s baseline health check with their status at follow-up, and trained AI models to predict future type 2 diabetes from the baseline data alone.

Separate studies examined DXA bone measurements, retinal (ophthalmoscopic) images, and respiratory and lung-function data, each fused with clinical records. The models were interpreted to find risk factors specific to the Qatari population, and to probe complication pathways such as respiratory health.

Key findings

AUROC for predicting future type 2 diabetes from longitudinal DXA bone scans, with accuracy above 91% (Scientific Reports, 2025)
0.96
AUROC for DiabEye-Q, combining retinal-image features with clinical data, with 88% accuracy (AIiH 2025)

OverviewWhy it matters · Research question and aims · Impact · Next steps

Why it matters

  • Diabetes can already be diagnosed cheaply with blood tests such as HbA1c. The real challenge is knowing who will develop it next, so prevention can start early.
  • Most AI studies look at one type of data at one point in time. This work followed the same people over time and combined many kinds of data.

Research question and aims

Can routine multimodal health-check data from Qatar Biobank predict who will develop type 2 diabetes years later, and which factors drive that risk?

  1. Predict incident type 2 diabetes in Qatari adults from longitudinal multimodal data.
  2. Combine imaging, bone, ECG, genetic, laboratory and lifestyle data and test which add predictive value.
  3. Compare deep learning, tabular transformers, classical machine learning and large language models on the same tasks.
  4. Identify and explain population-specific risk factors, including differences by age and sex.

Impact

To be added

Who benefits and how: patients, clinicians, health services, policy, training (e.g. "Model shared with HMC diabetes clinic")

Next steps

  • Extend to wearable sensors, continuous glucose monitoring and electronic health records.
  • Validate the models in other Gulf cohorts.
