The Effect of Video and Leaflet Media on Obesity Prevention Behavior and Diabetes Mellitus Risk among Junior High School Students

Abstract

Obesity is a serious public health problem that contributes to an increased risk of diabetes mellitus (DM) and other non-communicable diseases. Adolescents are a vulnerable group due to unhealthy diets and low physical activity. This study aimed to determine the effect of video media and leaflets on obesity prevention behaviors related to diabetes risk among students at SMP Negeri 10 Manado and SMP Negeri 1 Talawaan. The study used a quasi-experimental design with a two-group pretest-posttest design. A sample of 60 students was randomly selected and divided into two groups: video (30 students) and leaflet (30 students). The research instrument was a questionnaire that had been tested for validity and reliability. Data analysis was performed using an independent sample t-test with a significance level of α = 0.05. The results showed a significant difference in obesity prevention behaviors before and after the intervention in both media groups (p = 0.000 < 0.05). Video media utilized visual-audio stimuli that captured participants' attention and increased engagement. Meanwhile, leaflets had the advantage of being easy to reread, could be stored, and served as a practical source of information for students.
