The nutritional status of adolescents was influenced by chrononutrition. Chrononutrition has a significant relationship with nutritional status. However, there are no studies in Indonesia that specifically examine the relationship between chrononutrition and nutritional status, Mid Upper Arm Circumference (MUAC), and anemia in adolescent girls. Objectives: This study aimed to analyze the relationship between chrononutrition and nutritional status in adolescents. Methods: This study was cross-sectional, that was conducted in Senior High School in Widodaren, Ngawi, in August until september 2024.

There was relationship between chrononutrition namely breakfast skipping (p-value=0.003), night eating (p-value=0.001) and evening eating (p-value=0.03) with Anemia in Adolescent Girl.
