PENGARUH EDUKASI GIZI BERBASIS WEBSITE TERHADAP PERILAKU PENCEGAHAN ANEMIA PADA REMAJA PUTRI DI SMP NEGERI 4 PONTIANAK

Background: Anemia remains a nutritional problem commonly experienced by adolescent girls, primarily due to increased iron requirements during growth and blood loss during menstruation. Suboptimal anemia prevention behavior is one of the contributing factors to the high prevalence of anemia among adolescent girls. Website-based nutrition education is a medium that can be used to encourage changes in anemia prevention behavior because it is easily accessible and flexible.
Objective: This study aimed to determine the effect of website-based nutrition education on anemia prevention behavior among adolescent girls at SMP Negeri 4 Pontianak.
Methods: This study employed a quasi-experimental design with a one-group pretest–posttest approach. A total of 173 adolescent girls were selected using stratified random sampling. Anemia prevention behavior was measured using a questionnaire. Data analysis was conducted using univariate and bivariate analyses. Normality testing was performed using the Kolmogorov–Smirnov test, and bivariate analysis was conducted using the Wilcoxon test.
Results: The results showed that anemia prevention behavior among adolescent girls increased after receiving website-based nutrition education. The Wilcoxon test results showed a p-value of 0.000 (p < 0.05), indicating a significant effect of website-based nutrition education on anemia prevention behavior among adolescent girls.
Conclusion: Website-based nutrition education has a significant effect on improving anemia prevention behavior among adolescent girls at SMP Negeri 4 Pontianak.
