Effectiveness of Nutrition Booklets in Improving Nutritional Understanding Among High School Students

Abstract

Nutritional issues among adolescents, particularly high school students, pose a significant challenge in public health improvement efforts. A lack of nutritional understanding can
lead to poor dietary habits and long-term health impacts. This study aims to examine the effectiveness of booklets as a medium for nutrition education in enhancing high school students’
knowledge, attitudes, and behaviors regarding nutrition. A review was conducted on 10 relevant scientific articles published between 2021 and 2025, employing quasi-experimental, preexperimental, pre-posttest, and R&D methods. The findings indicate that booklets, whether in
print or digital form, significantly improve students’ nutritional knowledge and attitudes. Several
studies also highlight positive impacts on dietary behaviors and the prevention of health issues
such as anemia, chronic energy deficiency (CED), and dyspepsia. The highest effectiveness was
observed in interventions combining booklets with audiovisual media. This study confirms that
booklets are an effective, affordable, and flexible educational tool for adolescent nutrition education, supporting the achievement of Sustainable Development Goals (SDGs) in health and
nutrition.
