Siti Nurhaliza
Abstract
Anemia among adolescent females represents a health issue that can affect learning
concentration, productivity, and adolescent health. Inadequate knowledge regarding
anemia prevention can increase the risk of anemia occurrence. This study aimed to
determine the effect of anemia prevention education through leaflet and poster media
on adolescent female knowledge at State Junior High School 5 Jambi City. This study
was conducted from March to August 2026 using a true experiment design with a
pretest posttest control group design. The sample in this study comprised seventh grade
female students of State Junior High School 5 Jambi City divided into two groups,
namely an experimental group of 30 samples provided education using leaflet media
and a control group of 30 samples provided poster media as information without direct
education. Data were collected using anemia knowledge questionnaires before and
after intervention, then analyzed using paired samples t test and independent samples t
test. The research results demonstrated that the experimental group utilizing leaflets
experienced an average knowledge increase from 28.66 to 83.10 with a p value of 0.000,
where p is less than 0.05, whereas the control group utilizing posters increased from
30.22 to 34.88 with a p value of 0.226, where p is greater than 0.05. The independent
samples t test results revealed a difference in effectiveness between leaflet and poster
media with a p value of 0.000, where p is less than 0.05. Based on the research results,
it can be concluded that anemia prevention education using leaflet media affects
knowledge enhancement among adolescent females and is more effective compared to
poster media at State Junior High School 5 Jambi City.
