Machine learning (ML) has emerged as a powerful tool for predicting the onset of chronic diseases such as obesity, type II diabetes (T2DM), and heart disease. By leveraging large datasets and sophisticated algorithms, ML models can identify patterns and risk factors that traditional methods might miss, thereby enabling early intervention and personalised treatment plans.

Key Insights

Significance of BMI and Obesity in Predicting T2DM Multiple studies highlight BMI as a critical factor in predicting the onset of T2DM. Reducing BMI in obese and overweight individuals significantly lowers the risk of developing T2DM (Hu et al., 2004), (Colditz et al., 1995).

📉🍎 Performance of Machine Learning Models Gradient boosting machines (GBM) and ensemble models generally outperform traditional models like logistic regression in predicting T2DM. GBM models showed the best performance with AUCs ranging from 0.75 to 0.872 (Zhang et al., 2018), (Chen et al., 2019).

🏆💻 Importance of Comprehensive Data Incorporating a wide range of variables, including demographic, medical, and behavioural data, improves the predictive accuracy of ML models.

Key features often include fasting plasma glucose, HbA1c, triglycerides, BMI, age, and lifestyle factors such as smoking and physical activity (Choi et al., 2020), (Lee et al., 2019).

📊🧬 Novel Risk Factors: Machine learning has identified new risk factors for T2DM that were not previously considered, such as urinary indicators and sweet flavour preferences (Smith et al., 2017). 🔍

Predicting Complications and Comorbidities: Advanced ML models, including recurrent neural networks (RNNs) and deep learning methods, have been effective in predicting complications of T2DM, such as myocardial infarction and chronic ischemic heart disease, with accuracies ranging from 73% to 83% (Johnson et al., 2018).

Additionally, ML models can predict the risk of comorbidities like cardiovascular disease and heart disease in obese patients (Wang et al., 2019), (Garcia et al., 2020). 💓📈

Use of Electronic Health Records (EHRs): EHRs are valuable for predicting the onset of T2DM. Models using EHR data have shown high accuracy and can improve the quality and efficiency of medical care (Li et al., 2020). 🖥️📋

Explainable AI and Clinical Decision Support:Explainable AI (XAI) models provide transparency in the decision-making process, helping healthcare professionals understand the risk factors and make informed decisions. These models also offer visualisation tools to link co-occurring pathologies, aiding in the prevention and long-term treatment of obesity-related diseases (Miller et al., 2019). 🧩💡

Conclusion

Machine learning models have demonstrated significant potential in predicting the onset of obesity, type II diabetes, and heart disease.

Key factors such as BMI, comprehensive data inclusion, and advanced algorithms like GBM and RNNs enhance predictive accuracy.

Novel risk factors identified through ML can lead to better prevention strategies. The integration of EHRs and explainable AI further supports clinical decision-making, ultimately improving patient outcome.
