Nutritional status is a state of the body that is influenced by consumption, and eating habits. One of the most important factors in determining a person's health status is their nutritional status. Studies show that adolescents, especially in Islamic boarding schools, are at risk of experiencing nutritional problems due to unbalanced diets, lack of physical activity, and minimal awareness of the importance of monitoring nutritional status. In addition, the culture of eating together, lack of access to health information, and limited health facilities in Islamic boarding schools also worsen this situation. The lack of monitoring of adolescent nutritional status in the long term can have an impact on learning productivity, decreased immunity, and the risk of non-communicable diseases at an early age.
