Abstract

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 0·28 (+ 5·7 %, P = 0·02) and 0·30 points (+ 6·18 %, P = 0·02), respectively, but their fruit intake decreased by 0·36 serving/d (-22·9 %, P = 0·02) and 0·29 serving/d (-18·9 %, P = 0·03), respectively. Junior high school students' mean snacking frequency and fried food intake dropped to 0·75 d/week (-21·3 %, P = 0·008) and 0·10 serving/d (-28·8 %, P = 0·01), 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.
