<![CDATA[Anemia in adolescent girls remains a significant public health problem in Indonesia, particularly in island regions with limited access to health information and services. One of the main factors contributing to the high incidence of anemia is the low level of knowledge and attitudes among adolescent girls regarding the importance of consuming iron (Fe) tablets. Nutrition education is seen as a promotive-preventive strategy that has the potential to improve the determinants of anemia prevention behavior. This study aims to analyze the effect of nutrition education on the knowledge and attitudes of adolescent girls regarding the importance of consuming iron tablets in community health centers in the Morotai Islands. This study used a quasi-experimental design with a one-group pretest-posttest approach. The study sample consisted of 30 adolescent girls selected using a total sampling technique. Data were collected using a structured questionnaire to measure knowledge and attitudes before and after the nutrition education intervention. Data analysis was conducted descriptively and inferentially using paired statistical tests appropriate to the data distribution. The results showed an increase in the level of knowledge and attitudes of adolescent girls towards consuming iron tablets after being provided with nutrition education. Statistical tests showed a statistically significant difference between the conditions before and after the intervention in both knowledge and attitude variables. In conclusion, nutrition education significantly impacts adolescent girls' knowledge and positive attitudes toward iron tablet consumption. Structured and sustainable integration of nutrition education into primary healthcare services, particularly in island regions, is crucial to support anemia prevention efforts from adolescence onward.]]>
