Adolescent Girls Anemia Animated Video Health Education Leaflet
Abstract
Background: Anemia is a nutritional issue frequently experienced by adolescent girls due to increased iron requirements during puberty, rapid growth, and inadequate nutritional intake. This condition can negatively impact learning concentration, academic performance, and future reproductive health. Despite various prevention programs, some adolescent girls still demonstrate low levels of knowledge and poor adherence to taking blood-supplementing tablets (iron supplements).
Purpose: To determine the influence and effectiveness of health education using animated videos combined with leaflets in improving knowledge regarding anemia prevention among adolescent girls.
Method: This study employed a quantitative approach with a quasi-experimental design and a two-group pretest-posttest structure. The research was conducted from April 13 to April 20, 2026, at State Junior High School 11 Samarinda. Purposive sampling was used to recruit 48 participants, who were divided into two groups: an intervention group (24 participants) and a control group (24 participants). The independent variable was health education using animated videos and leaflets, while the dependent variable was the level of knowledge regarding anemia prevention among the adolescent girls. The control group received education via lectures and leaflets, whereas the intervention group received education via lectures supported by leaflets and animated videos. The collected data were statistically analyzed to assess differences and the impact of the health education intervention on improving participants' knowledge.
Results: The study results showed that the majority of participants were 15 years old (58.3%) and in the 11th grade (54.2%). Most parents had a secondary education level (64.6%), and the majority worked as traders (50.0%). The majority of participants fell into the non-adherent category regarding the consumption of blood-supplementing tablets (70.8%). The intervention group experienced an increase in mean knowledge scores from 65.79 ± 12.70 points to 87.46 ± 9.67 points, with a p-value of < 0.000. The control group also showed an increase from 63.17 ± 15.61 points to 81.88 ± 10.14 points (p < 0.000). Meanwhile, the difference between the control group and the intervention group yielded a p-value of 0.057.
Conclusion: Health education utilizing animated video media combined with leaflets proved effective in increasing adolescent girls' knowledge regarding anemia prevention. Although both groups experienced a significant increase in knowledge, the intervention group demonstrated higher average scores.
Suggestion: Schools are advised to incorporate health education as a routine, integrated activity within the school program and to collaborate with healthcare professionals to conduct educational sessions using interactive, engaging learning media that are easier for students to understand.
