Female students in Islamic boarding school are one of the vulnerable groups to experience nutritional problems caused by several factors, one of which is because there are traditions that can change eating patterns. Changes in eating patterns can be caused by fasting traditions, such as Daud and Ngrowot. Objectives: This study aims to analyze the differences in nutritional status and body composition among female students based on type of fasting habits. This research is an observational analytical study with a cross sectional design at API Asri Syubbanul Wathon Islamic Boarding School Tegalrejo, Magelang in female students aged 16-18 years who were selected using stratified random sampling techniques.
