Predicting Adolescent Concern Over Unhealthy Food Ads Using Explainable AI

Year: 2025

Type: article

Abstract: Machine learning and explainable AI techniques are powerful tools to analyze the influence of unhealthy food ads on health awareness and concern levels. This research aims to predict levels of concern about unhealthy food advertisements and ascertain significant demographic and behavioral variables that modify the need for these concerns. A survey was conducted, and responses from 1030 adolescents were gathered on their knowledge about food advertisements and what affects their perceptions toward health. Stacking Ensemble, Random Forest, and XGBoost with hyperparameter optimization and synthetic oversampling techniques were applied to predict three categories of concern levels in unhealthy food advertisements. Stacking Ensemble, utilizing Random Forest, K-Nearest Neighbors, and Support Vector Machines as base learners and Logistic Regression as the meta-learner, yielded the highest prediction accuracy of 98.54% and an F1 score of 0.99. The most relevant features for predicting the food advertisement concern levels were age, parental education and advertisement types, such as free toys and celebrity endorsement. LIME, an interpretation protocol, has been used to enable a proper understanding of how advertisement strategies influence adolescent health awareness. The developments resulted from growing research efforts in which predictive analytics is connected to explainability in understanding and mitigating the adverse influence of unhealthy food advertisements. The results bear implications at the onset of public health policy, advertising regulation, and educational campaigns against improved adolescent dietary behaviors and awareness.
