Background: Increasing obesity sufferers every year, in a few decades becomes an impor­tant problem. Increased obesity can lead to an increa­s­­ed risk of degenerative diseases which can cause death. Several attempts have been made to prevent and treat obesity. The pur­­­pose of this study is to determine the effective­­ness of peer edu­­ca­tion on knowledge, attitudes, and con­sump­­tion of fast food in adolescents.

Subjects and Method: This study is a ran­do­m­ized controlled trial conducted at a Junior High School (SMP Ne­geri 6 Medan), North Su­matera. Samples taken were 60 stu­dents chosen random­ly. The sample was divided into 2 groups: a peer game edu­cation leaf­let group and a peer edu­cation modu­le group. The depen­dent va­r­i­­­able is know­ledge, attitudes, and habits of fast fo­od con­sumption. The indepen­dent vari­able is the pro­vision of leaflets and peer edu­ca­tion mo­du­­les. The data were obtained through in­­­ter­­­­­view, Food Frequency Question­naire (FFQ), and Food Re­call 24 hours. Data were analy­z­ed using t-test.

Results: The results showed that the value of nut­ritional knowledge and obesity in the control group (Mean= 12.07; SD= 1.44) was lower com­pared to the intervention group (Mean= 13.50; SD= 1.99), but not statistically significant (p= 0.523). Attitudes toward nutrition and obesity in the control group (Mean= 11.50; SD= 1.22) were low­er than those in the intervention group (Mean = 13.00; SD= 1.78) and were statistically proven sig­nifi­cant (p= 0.008). The score of fast food con­­sumption habits in the control group (Mean= 8.17; SD= 1.23) is lower than that of the inter­vention group (Mean= 9.50; SD= 1.17) and is statis­tically proven significant (p <0.001).

Conclusion: The nutrition peer education mo­dule has been shown to be effective in increas­­ing attitudes about nutrition and obesity and redu­cing fast food consumption habits and this has been statistically significant. The nutri­tion peer education module increases know­ledge scores, but is not statistically significant.
