The Effectivity of Nutrition Education Booklet on Knowledge, Fast-food Consumption, Calorie Intake, and Body Mass Index in Adolescents

Abstract

Background: The prevalence of adolescent obesity is increasing worldwide with proportions varying from country to country or between geo­graphical regions within a country. The purpose of this study was to determine the effect of nutri­tion education with booklet media on know­ledge, fast food consumption, calorie intake, and body mass index (BMI) in adolescents. Subjects and Method: This was a quasy experiment with no control group. The study was conducted in Junior high school in Medan, North Sumatera. A sample of 31 adoles­cents was selec­ted by purpo­sive sampling. The depen­­dent vari­ables were know­l­edge, fast-food consumption, ca­lorie intake, and BMI. The independent vari­ables were booklet media. Means of knowledge, fast food consumption, calorie intake, and BMI before and after intervention was examined by t-test. Results: Mean of knowledge after intervention (Mean= 12.90; SD= 2.71) was higher than before (Mean= 8.77; SD= 1.54) and it was statisticaly significant (p<0.001). Mean of fast food con­sump­tion after intervention (Mean= 9.48; SD= 1.38) was lower than before (Mean= 10.03; SD= 1.16) and it was statistically significant (p= 0.007). Mean of calorie intake after intervention (Mean= 2735.12; SD= 1999.9) was lower than before (Mean= 2821.09; SD= 216.13) and it was statistically significant (p= 0.003). BMI after intervention (Mean= 26.58; SD= 2.49) was equal with before intervention (Mean= 26.81; SD= 2.49). Conclusion: Nutrition education with booklet improves knowledge, reduces fast food con­sump­tion, and reduce calorie intake.
