Abstract

Hemoglobin is a component of red blood cells in the form of a conjugated protein that functions to transport oxygen and carbon dioxide. Hemoglobin can be used to determine whether someone is anemic or not by measuring hemoglobin levels. Decreased hemoglobin levels indicate a condition of anemia, namely anemia. Adolescent girls are at risk of anemia because they menstruate every month, thus requiring a large intake of iron. Irregular menstruation can be caused by stress factors, food consumption, physical activity, and genetic factors. An abnormal menstrual cycle causes adolescent girls to experience excessive bleeding during menstruation. This type of research is descriptive in nature, which aims to determine the description of nutritional intake and hemoglobin levels in adolescents at MTs Al-Muhajirin Ambon. The study was conducted in January 2025, located at MTs Al-Mahjirin Ambon. The sample in this study was 53 people, with a sampling method using accidental sampling. The variables in this study were protein intake, vitamin C, iron, and hemoglobin levels. Protein intake is less than <55% of the requirement, good at 55-65% of the requirement, and more than 65% of the requirement. Vitamin C intake is less than 77% of the RDA and sufficient at ≥77% of the RDA. Iron intake is less than 77% of the RDA or sufficient at ≥77% of the RDA. Anemia if hemoglobin is <11 gr/dL and not anemic if hemoglobin is >11 gr/dL. Intake data was collected by interviewing each teenager. Hemoglobin level data was collected using a digital HB test tool. The data collection instrument was an FFQ-semi-quantitative questionnaire. The results showed that respondents' protein intake was in the excess category, namely 69%; vitamin C intake was 88%; iron intake was sufficient, namely 66%; and not anemic as many as 58%.
