A Cosmetic Content-Based Nutrition Education Program Improves Fruit and Vegetable Consumption Among Grade 11 Thai Students.

OBJECTIVE To examine and compare the effectiveness of a cosmetic content-based nutrition education (CCBNEd) program and a health content-based nutrition education (HCBNEd) program on the promotion of fruit and vegetable (F&V) consumption. DESIGN Quasi-experimental. SETTING Three secondary schools in Nonthaburi, Thailand. PARTICIPANTS/INTERVENTIONS Three classes of students were randomly assigned to 3 study groups: experimental group 1 (n = 41) participated in the CCBNEd program, experimental group 2 (n = 35) experienced the HCBNEd program, and a comparison group (n = 37) did not participate in a program. All groups received F&V information. Data were collected between July and September, 2013. MAIN OUTCOME MEASURES Knowledge about F&V, attitude toward F&V consumption, and the amount and variety of F&V consumed were measured at baseline, posttest, and follow-up. ANALYSIS Nonparametric statistics were used to compare the programs' effectiveness. RESULTS After the test, experimental group 1 had significantly increased knowledge scores, attitude scores, and the amount and variety of F&V consumed compared with those at baseline (P < .001). These positive changes were maintained until follow-up. In experimental group 2, knowledge and attitude scores increased (P < .001) at posttest and then decreased at follow-up whereas the comparison group positively changed only in knowledge. CONCLUSIONS AND IMPLICATIONS The CCBNEd program was most effective at increasing F&V consumption.
