Adolesence is an important life period and has crucial importance for the development of
appropriate eating habits and a healthy diet. Dietary and educational interventions may help
improving diet and thus may provide prevention from the development of lifestyle related
diseases during both adolescence and in the future adulthood. Peer-led-nutritional-education
(PLNE) (n=36); video-mediated-nutrition-education (VMNE) (n=36); nutrition-education-withvisual-
tools (NEGVT) (n=36); and traditional-nutrition-education (TNE) (n=108) were
performed.The aim of this population based educational intervention study with a pretest-posttest
design study was to evaluate the effectiveness of different nutrition education methods on
nutrition knowledge level in vocational high school students in Istanbul, Turkey. A total of 216
students from 3 high schools in Usküdar, Istanbul were randomly assigned to three different
educational intervention method groups (video-mediated, peer-directed and visual aids), each
consisting of 72 students to compare the effectiveness with the traditional education method.
Before and after each training, nutrition knowledge level of adolescents were evaluated with
Adolescent-Nutrition-Knowledge-Level (ABBID) questionnaire which includes subunits of
adequate and balanced nutrition; essential nutrients, and malnutrition related diseases with a total
score between 0 to 38. Shapiro-Wilk test, Mann Whitney U test, Wilcoxon Signed test and
Spearman rho correlation analysis were applied for statistical analyses. All methods provided
significantly increased post-test total scores compared to pre-test scores(p<0.05). Participants in
PLNE had significantly higher post-test scores in all subunits of questionnaire than the
participants of TNE(p<0.05). This study provides the efficacy and superiority in the success of
peer led nutrition education method among adolescence. Further educational studies are required
for the determination of the long-term effects of selected education on nutrition knowledge
levels, habits, and behaviors of adolescents.
