Abstract

This study aims to analyze the nutritional status on Body Mass Index and macronutrient requirements of students aged 13-14 years at SMP Negeri 4 Bangli. This research is a quantitative descriptive research with a survey method. The population consisted of 110 eighth-grade students, with 54 students selected through stratified cluster random sampling. Anthropometric measurements were conducted to determine BMI, while daily energy requirements were calculated based on Basal Metabolic Rate (BMR), Specific Dynamic Action (SDA), physical activity level, and growth factors. The results showed that of the 54 students of SMP Negeri 4 Bangli who were studied, there were 12 students (22%) who were mildly thin, there were 7 students (13%) who were severely thin, 26 students (48%) had ideal/normal nutritional status, 3 students (6%) were mildly obese, and 6 students (11%) were severely obese. The average daily energy requirement is 1538.14 kcal, consisting of a carbohydrate requirement of 1758.74 kcal or 439.68 grams per day. The average fat requirement is 732.81 kcal or 81.42 grams per day. The average protein requirement is 439.68 kcal or 109.92 grams per day. egular monitoring of nutritional status and nutrition education in the school environment are important to support optimal growth and prevent nutritional problems among adolescents.
