This study aimed to analyze the relationship between nutritional knowledge, dietary intake, physical activity, and nutritional status. A cross-sectional study was conducted from October to November 2025 involving 91 adolescents. Dietary intake was assessed using a non-consecutive 2×24-hour food recall, physical activity using PAQ-A, and nutritional status based on WHO 2007 BMI-for-age standards.
