Abstract


Anemia in adolescent girls remains a major nutritional problem and is influenced not only by inadequate iron intake but also by limited knowledge regarding foods that enhance (enhancer) and inhibit (inhibitor) iron absorption. This study aimed to determine the effectiveness of motion graphic video-based nutrition education on adolescents’ knowledge of iron absorption enhancer and inhibitor foods.A quasi-experimental study with a pretest–posttest with control group design was conducted at MTs Negeri 1 Kota Cirebon in July 2026. Thirty-four female students were selected using purposive sampling and divided into an intervention group (n=17) and a control group (n=17). The intervention group received a 30 minute nutrition education session using a motion graphic video containing information about anemia, iron absorption enhancers, and iron absorption inhibitors, while the control group did not receive the educational intervention. Knowledge data were collected using a structured questionnaire and analyzed using the Mann–Whitney and Wilcoxon tests with a significance level of p<0.05. The baseline knowledge scores of the control and intervention groups were similar (62.28±11.68 vs. 62.35±9.66; p=0.944). After the intervention, the mean knowledge score increased to 87.82±9.41 in the intervention group, whereas the control group increased to 68.12±11.53. The difference between groups at endline was statistically significant (p<0.001). In conclusion, motion graphic video-based nutrition education was effective in improving adolescents’ knowledge regarding anemia and foods that enhance and inhibit iron absorption, indicating its potential as an innovative educational medium to support anemia prevention programs among adolescent girls.
