Abstract
Iron deficiency anemia remains a significant public health problem among adolescent girls due to increased iron requirements during growth and menstruation. This study aimed to describe the level of knowledge about iron deficiency anemia among adolescent girls at SMP Negeri 1 Mamuju. This study used a descriptive design with a quantitative approach. The population consisted of all female students at SMP Negeri 1 Mamuju, totaling 156 students, with a sample of 108 respondents determined using the Slovin formula and proportional random sampling technique. Data were collected using a structured questionnaire covering the definition of anemia, causes, signs and symptoms, impacts, and prevention efforts of iron deficiency anemia. Data analysis was conducted descriptively using univariate analysis to determine frequency distribution and percentages. The results showed that most respondents were 14 years old (50.0%), and the majority were from grade VIII (54.6%). Based on the level of knowledge, most respondents had good knowledge about iron deficiency anemia, totaling 95 respondents (88.0%), while 13 respondents (12.0%) had poor knowledge. These findings indicate that most adolescent girls already have good knowledge about iron deficiency anemia. However, strengthening nutrition and health education in the school environment is still necessary to improve understanding and encourage preventive behaviors against anemia among adolescents.
