Prediction of blood glucose (BG) values in type 1 diabetes (T1D) remains an essential and challenging issue. Recently, machine learning methods have been used to solve this problem. We present a forecasting model based on extreme gradient boosting (XGBoost) regression to estimate the BG value of T1D patients in this study. We developed the models using clinical datasets from five T1D patients and forecasted the BG value for the following prediction horizons (PHs) of 10, and 20 minutes. Datasets are divided in two parts, around 60:40 for training and testing. We compared the performance of our proposed model to existing models using several performance metrics, including root mean square error (RMSE), mean absolute percentage error (MAPE), and coefficient of determination (R2). Our suggested XGBoost model outperformed existing models, with average RMSE, MAPE, and R2 of 12.57 mg/dL, 7.15%, 0.94, and 21.93 mg/dL, 13.72%, 0.84 for PH of 10 and 20 minutes, respectively. Finally, the findings of this study are intended to be applied to improve diabetes care.
