Nutritional status is a fundamental indicator of health, reflecting the physiological balance between nutrient intake from food and the body's metabolic requirements. Adolescence represents a critical window of vulnerability for nutritional issues due to rapid physical growth, autonomy in food choices, and shifting lifestyle behaviors. In this demographic, snacking habits often contribute significantly to daily caloric intake but may lack nutritional quality. This study aimed to determine the specific relationships between energy, macronutrient intake, and the glycemic index of snack foods with the nutritional status of adolescents at SMAN 07 Bengkulu City in 2025. Employing a quantitative descriptive-analytic design with a cross-sectional approach, the research assessed these variables comprehensively. The sample consisted of 60 students selected through simple random sampling to ensure representativeness. Data were rigorously collected using the Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ) for dietary assessment, alongside digital body weight scales and microtoise for anthropometric measurements. Bivariate analysis using the Chi-square test revealed that the intake of energy, proteins, fats, and carbohydrates from snacks had a statistically significant relationship with nutritional status (p-value < 0.05). Interestingly, the glycemic index of snacks showed no significant correlation (p-value = 0.176). These findings suggest that for this population, the macronutrient composition and caloric density of snacks are more critical determinants of health than glycemic index, necessitating targeted nutritional education to improve adolescent snacking behaviors.
