To evaluate the efficacy of a school-based education intervention on the consumption of fruit, vegetables and carbonated soft drinks among adolescents.
Cluster-randomised controlled trial.
Eight secondary schools from Dhaka, Bangladesh, participated in this trial and were randomly allocated to intervention ( 160) and control groups ( 160).
A total of 320 students from 8th to 9th grades participated and completed the self-reported questionnaires at baseline, and at 8 and 12 weeks. The intervention included weekly classroom-based nutrition education sessions for students and healthy eating materials for students and parents. Repeated measures ANCOVA was used to assess the effects of the intervention.
Daily fresh fruit intake was more frequent in the intervention (26 %) compared to the control group (3 %) at 12 weeks ( = 0·006). Participants from the intervention group also reported a significantly ( < 0·001) higher (49 %) proportion of fresh vegetable intake compared to the control group (2 %) at 12 weeks. Frequency of daily carbonated soft drinks intake decreased (25 %) in the intervention group at 12 weeks compared to baseline, while it remained unchanged in the control group; the interaction effect was observed significant ( = 0·002).
Our school-based education intervention increased the daily frequency of fresh vegetables and fruit intake and decreased carbonated soft drink consumption among adolescents in the intervention group. There is a need for scaling up the intervention to engage students and empower them to develop healthy dietary habits.
评估基于学校的教育干预对青少年水果、蔬菜和碳酸软饮料消费的效果。
整群随机对照试验。
孟加拉国达卡的 8 所中学参与了这项试验，并被随机分为干预组（160 人）和对照组（160 人）。
共有 320 名 8 至 9 年级的学生参与并在基线、8 周和 12 周完成了自我报告的问卷。干预措施包括每周为学生提供课堂营养教育课程以及为学生和家长提供健康饮食材料。采用重复测量方差分析评估干预的效果。
在 12 周时，干预组（26%）比对照组（3%）更频繁地摄入新鲜水果（ = 0·006）。干预组的参与者还报告说，与对照组（2%）相比，12 周时新鲜蔬菜的摄入量明显更高（49%）（ < 0·001）。在 12 周时，干预组的碳酸软饮料日摄入量下降（25%），而对照组则保持不变；观察到交互作用有统计学意义（ = 0·002）。
我们的基于学校的教育干预增加了青少年每日新鲜蔬菜和水果的摄入量，并减少了碳酸软饮料的消费。需要扩大干预范围，让学生参与其中，增强他们养成健康饮食习惯的能力。
