Diabetes Risk Prediction Exploration: Uncovering Patterns and Enhancing Predictive Accuracy through Ensemble Learning

Diabetes, recognized as a chronic noncommunicable condition, has become increasingly prevalent and now affects an estimated 425 million individuals worldwide as of 2020. This escalating global prevalence underscores the urgent need for comprehensive research initiatives to address this significant health challenge. Undiagnosed diabetes poses grave risks, including serious complications such as cardiac stroke and diabetic nephropathy, emphasizing the critical importance of early detection and intervention. Leveraging ensemble learning methods like Gradient Boosting, Random Forest, XGBoost, and AdaBoost, this study aims to construct a robust machine learning framework for precise diabetes classification, utilizing pertinent health indicators from the BRFSS dataset. Through rigorous evaluation, Gradient Boosting emerged as the most effective model, achieving an accuracy of 84.85%. This finding highlights the potential of ensemble learning techniques in refining predictive accuracy for diabetes risk assessment and ultimately improving patient outcomes, contributing significantly to the advancement of diagnostic tools in combating this global health challenge. The results underscore the importance of continued research in leveraging machine learning for enhancing diabetes management and public health strategies.
