The aim of the study was to evaluate the effectiveness of implementing multimodal nutrition education intervention (NEI) to improve dietary intake among university students. The design of study used was cluster randomised controlled design at four public universities in East Coast of Malaysia. A total of 417 university students participated in the study. They were randomly selected and assigned into two arms, that is, intervention group (IG) or control group (CG) according to their cluster. The IG received 10-week multimodal intervention using three modes (conventional lecture, brochures, and text messages) while CG did not receive any intervention. Dietary intake was assessed before and after intervention and outcomes reported as nutrient intakes as well as average daily servings of food intake. Analysis of covariance (ANCOVA) and adjusted effect size were used to determine difference in dietary changes between groups and time. Results showed that, compared to CG, participants in IG significantly improved their dietary intake by increasing their energy intake, carbohydrate, calcium, vitamin C and thiamine, fruits and 100% fruit juice, fish, egg, milk, and dairy products while at the same time significantly decreased their processed food intake. In conclusion, multimodal NEI focusing on healthy eating promotion is an effective approach to improve dietary intakes among university students.
本研究的目的是评估实施多模式营养教育干预(NEI)对改善大学生饮食摄入量的有效性。本研究采用的设计是在马来西亚东海岸的四所公立大学进行整群随机对照设计。共有417名大学生参与了该研究。他们被随机抽取并根据其所在群组分为两组,即干预组(IG)或对照组(CG)。干预组接受了为期10周的使用三种模式(传统讲座、宣传册和短信)的多模式干预,而对照组未接受任何干预。在干预前后评估饮食摄入量,并将结果报告为营养素摄入量以及食物摄入量的平均每日份数。使用协方差分析(ANCOVA)和调整后的效应量来确定两组之间以及不同时间饮食变化的差异。结果表明,与对照组相比,干预组的参与者通过增加能量摄入、碳水化合物、钙、维生素C和硫胺素、水果和100%果汁、鱼类、蛋类、牛奶和乳制品的摄入量,显著改善了他们的饮食摄入量,同时显著减少了加工食品的摄入量。总之,以促进健康饮食为重点的多模式营养教育干预是改善大学生饮食摄入量的有效方法。
