The study found that short-term after-school nutrition education programs can effectively increase adolescents' nutrition knowledge, reduce snacking frequency and fried food intake, despite a decrease in fruit intake during the intervention.
Objective: To investigate whether an after-school nutrition education (ASNE) programme can improve the nutrition knowledge and healthy eating behaviour of adolescents from economically disadvantaged families. Design: One-group pretest and posttest design. Nutrition knowledge and dietary intake were collected using a questionnaire, and anthropometric measurements were measured before and after the intervention. Nine components of healthy eating behaviour were assessed with reference to the Dietary Guideline of Taiwan. Pretest and posttest differences were analysed using generalised estimating equations. Setting: Three after-school programmes in central and southern Taiwan. The ASNE programme comprised three monthly 1-h sessions (20-30-min lecture and 30-40-min interaction). Participants: A total of 153 adolescents aged 10-15 years from economically disadvantaged families (seventy-eight elementary students and seventy-five junior high school students). Results: Elementary and junior high school students' nutrition knowledge scores (range 0-6) increased by 0 center dot 28 (+ 5 center dot 7 %, P = 0 center dot 02) and 0 center dot 30 points (+ 6 center dot 18 %, P = 0 center dot 02), respectively, but their fruit intake decreased by 0 center dot 36 serving/d (-22 center dot 9 %, P = 0 center dot 02) and 0 center dot 29 serving/d (-18 center dot 9 %, P = 0 center dot 03), respectively. Junior high school students' mean snacking frequency and fried food intake dropped to 0 center dot 75 d/week (-21 center dot 3 %, P = 0 center dot 008) and 0 center dot 10 serving/d (-28 center dot 8 %, P = 0 center dot 01), respectively. Conclusions: Short-term ASNE programmes can increase nutrition knowledge and reduce snacking frequency and fried food intake despite a decrease in fruit intake among adolescents from economically disadvantaged families.
