<![CDATA[Type 2 diabetes is increasingly common in children and adolescents. Lifestyle choices such as obesity, lack of physical activity, and unhealthy diets are becoming increasingly popular among adolescents. An unhealthy lifestyle is influenced by many factors, including inadequate knowledge and attitudes regarding diabetes mellitus prevention. Good knowledge will foster positive attitudes regarding diabetes mellitus prevention. Through booklets, a person's knowledge and attitudes can be improved. The objective was to determine the effect of booklets on knowledge and attitudes regarding diabetes mellitus prevention in adolescent girls. The method used was a quasi-experimental study with a pretest-posttest design with a control group. This study was conducted at SMAN 1 Jasinga and SMK Giri Taruna. A sample of 70 students was used using a stratified random sampling technique. Data collection used a questionnaire as the research instrument. The data analysis techniques used were the Independent T-test and Chi-square test. The results showed an effect of booklets on knowledge regarding diabetes mellitus prevention in adolescent girls (p-value 0.003). There was a correlation between knowledge and attitudes regarding diabetes mellitus prevention in adolescent girls (p-value 0.016). The booklet can be used as an educational tool for adolescents, and educators can be more active in providing education about diabetes mellitus prevention to students, especially adolescent girls.]]>
