Nutritional anemia results from deficiencies in nutrients essential for hemoglobin formation, either due to inadequate intake or impaired absorption

Abstract

Nutritional anemia results from deficiencies in nutrients essential for hemoglobin formation, either due to inadequate intake or impaired absorption. The impact of anemia on adolescents includes decreased work productivity, reduced academic performance due to poor concentration, lower physical activity, and diminished learning achievement. This study aimed to determine the effect of nutrition education on the knowledge of anemia before and after the intervention among female adolescents at State Senior High School 1 of Seputih Mataram of Central Lampung in 2025. This research employed a quantitative approach with a pre-experimental method using a one-group pretest–posttest design. The study population consisted of all female students in grades X and XI, totaling 407 students. A sample of 80 respondents was selected using cluster sampling. Data were collected using a structured questionnaire, and analysis was performed using a paired samples test. The results showed that the average knowledge score regarding anemia before the intervention was 60.81 (moderate knowledge), which increased to 82.70 (good knowledge) after the intervention. A significant effect of nutrition education on anemia-related knowledge was found, as indicated by a p-value of 0.000 (p < 0.05). It is recommended that female adolescents routinely consume iron supplementation tablets (one tablet per week) and eat a balanced, nutrient-rich diet high in iron from both animal sources (meat, liver, eggs) and plant sources (green vegetables, fruits). Additionally, iron absorption can be enhanced by consuming foods rich in vitamin C.
