Nocturnal Hypoglycemia Prediction in Diabetic Children Participating in a Sports Day Camp - First Results
Keywords: Biomedical signal processing, Digital Health, Hypoglycemia Prediction, Machine learning
TL;DR: Machine learning models are used to predict the risk of hypoglycemia in children with type 1 diabetes at bedtime for the upcoming night.
Abstract: Nocturnal hypoglycemia is frequent in children with type 1 diabetes (T1D), daytime physical activity being the most important risk factor.
The risk for late postexercise hypoglycemia depends on various factors and is difficult to anticipate. The availability of continuous glucose monitoring (CGM) enabled the development of various machine learning approaches for nocturnal hypoglycemia prediction for different prediction horizons.
Studies focusing on nocturnal hypoglycemia prediction in children are scarce, and none, to the authors' best knowledge, investigate the effect of previous physical activity.
In this work, continuous glucose and physiological data from a sports day camp for children with T1D were input for logistic regression, random forest, and deep neural network models. Results were evaluated using the F2 score, adding more weight to misclassifications as false negatives.
Data of 13 children (4 female, mean age 11.3 years) were analyzed. Nocturnal hypoglycemia occurred in 18 of a total included 66 nights. Random forest achieved best results for nocturnal hypoglycemia prediction.
Predicting the risk of nocturnal hypoglycemia for the upcoming night at bedtime is clinically highly relevant, as it allows appropriate actions to be taken - to lighten the burden for children with T1D and their families.
