Abstract

Nutritional anemia, particularly iron deficiency anemia, is a significant public health problem among adolescent girls, with a prevalence of 45.9% in Bali. One contributing factor to this high rate is the low adherence to iron supplement consumption, which is influenced by limited understanding of its benefits. Visual education, such as banners, is considered potentially effective in improving knowledge and adherence to iron supplement consumption. Methods: This study employed a pre-experimental one-group pretest-posttest design involving 33 adolescent girls at SMP Dwi Jendra Denpasar who received nutrition education about anemia using banners. Students' knowledge was measured using a multiple-choice questionnaire administered before and after the education session. The data were analyzed descriptively and quantitatively using paired t-test to determine the significance of score changes. Results: Knowledge scores significantly increased from a mean pretest score of 58.2 (SD=7.3) to a posttest score of 96.0 (SD=5.0), with p < 0.001. The increase in scores indicates that the educational intervention using banners was effective in improving nutrition literacy about anemia. Conclusion: Nutrition education using banners was proven effective in increasing students' knowledge about anemia and the importance of iron supplement consumption. Visual media like banners can be used as a simple yet meaningful educational approach in school-based anemia prevention programs. This study supports the integration of visual media in School Health Units (SHU) as a preventive nutrition promotion effort with direct impact.
