Abstract

Excessive consumption of junk food among students has become a significant health issue that requires attention. This study aims to analyze the determinants of student motivation for consuming junk food at SMKS PGRI 17 Lohsari, Labuhan Batu Selatan. The research is observational-analytic with a cross-sectional design. It was conducted at SMKS PGRI 17 Lohsari, Labuhan Batu Selatan, from November 2023 to January 2024. The population consisted of all X and XI grade students, totaling 233 students. The sample size was calculated using Slovin's formula, resulting in a sample of 70 students. Data collection was performed using primary data obtained from respondents through questionnaires. Data analysis was conducted using SPSS software version 21. The data analysis involved three stages: univariate analysis using frequency, bivariate analysis using the chi-square test, and multivariate analysis using multiple logistic regression. The study results indicated that factors significantly related to student motivation for consuming junk food included pocket money (P-value = 0.034), physiological needs/hunger (P-value = 0.004), the need for acceptance (P-value = 0.001), esteem needs (P-value = 0.001), the delicious taste of junk food (P-value = 0.001), the influence of junk food advertisements (P-value = 0.001), and the availability of junk food (P-value = 0.001). The most dominant factors influencing student motivation for consuming junk food at SMKS PGRI 17 Lohsari, Labuhan Batu Selatan, were esteem needs (P-value = 0.016; Exp(B) = 1.439) and junk food advertisements (P-value = 0.001; Exp(B) = 37.90). It is recommended that a comprehensive intervention involving the school, family, and community is necessary to address this issue
