Evaluating Machine Learning Approaches for Predicting Metabolic Syndrome Risk in Quebec
In the ever-evolving landscape of healthcare, the integration of machine learning offers promising advances in predictive diagnostics, particularly for conditions such as metabolic syndrome (MetS). This condition, characterized by a cluster of risk factors including high blood pressure, elevated blood sugar, and abnormal cholesterol levels, is a significant public health concern due to its association with increased risk of cardiovascular diseases and type 2 diabetes. A recent study has focused on employing machine learning techniques to predict the risk of MetS within the population of Quebec, Canada, using self-reported health data from the Canadian Community Health Survey (2015–2018).
Methods and Analysis
The study adhered to the Minimum Information about Clinical Artificial Intelligence Modeling (MI-CLAIM) guideline for transparent and rigorous reporting. The dataset comprised 42,279 participants from Quebec, and a balanced dataset was created through partial sampling to enhance the reliability of model development. Seven machine learning models were evaluated: Logistic Regression, XGBoost, LightGBM, TabNet, NODE, 1D-CNN, and Regularization Cocktails. These models were assessed using various metrics such as accuracy, precision, recall, F1 score, AUROC, and AUPRC. To add another layer of insight, SHAP (SHapley Additive exPlanations) was utilized to elucidate the influence of different features on MetS risk predictions.
Results
Following subsampling, the analysis included 7,866 participants, with 4,856 classified as high-risk MetS cases and 3,010 as low-risk. Among the machine learning models, XGBoost and NODE stood out due to their superior performance. XGBoost achieved the highest accuracy at 80.4% and an AUROC of 84.1%, while NODE excelled in precision with 80.1% and an AUPRC of 86.0%. The explainability analysis identified age, perceived health, and gender as crucial predictors, aligning with established clinical findings regarding MetS risk factors.
Diploma
This study underscores the potential of machine learning to accurately forecast MetS risk by leveraging self-reported health data from the Quebec population. By comparing traditional machine learning models with deep learning approaches, researchers were able to pinpoint the most effective prediction model, supported by an explainability analysis that highlighted key risk factors consistent with existing clinical evidence. The findings advocate for a machine learning-driven initial screening framework that can facilitate the early identification of high-risk individuals, thereby enabling targeted interventions and optimizing healthcare resource allocation.
