In plain language

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.

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.

Overview

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.

Research question

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

Objectives

  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.

Approach and data

  • Longitudinal Qatar Biobank data, with baseline records labelled by diabetes status at follow-up.
  • DXA study: 1,382 participants; feature engineering on 263 bone measurements and a tabular transformer fused with clinical data.
  • Retinal study (DiabEye-Q): 2,043 participants; fractal features from retinal images combined with clinical data using XGBoost and a Vision Transformer.
  • Interpretation of model predictions and analysis by age group and sex.
