Abstract：
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.
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.
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).
A total of 153 adolescents aged 10-15 years from economically disadvantaged families (seventy-eight elementary students and seventy-five junior high school students).
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.
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.

摘要：
目的探讨课后营养教育(ASNE)计划是否能改善经济困难家庭青少年的营养知识和健康饮食行为。
一组前测和后测设计。使用问卷收集营养知识和饮食摄入量，并在干预前后测量人体测量值。参考台湾的饮食指南，评估了健康饮食行为的9个组成部分。使用广义估计方程分析了前测和后测差异。
台湾中部和南部的三个课余课程。ASNE计划包括三个每月1小时的课程（20-30分钟的讲座和30-40分钟的互动）。
共有153名10-15岁的青少年来自经济困难家庭（78名小学生和75名初中生）。
中小学生的营养知识得分（0-6）增加了0·28（5·7％，P=0·02)和0·30分(+6·18%，P=0·02)，分别,但他们的水果摄入量减少了0·36份/天(-22·9%，P=0·02)和0·29份/天(-18·9%，P=0·03)，分别。初中生平均吃零食频率和油炸食物摄入量降至0·75d/周(-21·3%，P=0·008)和0·10份/天(-28·8%，P=0·01)，分别。
短期ASNE计划可以增加营养知识，减少吃零食频率和油炸食品的摄入量，尽管来自经济弱势家庭的青少年的水果摄入量减少。
