This study assessed sociodemographics, general health, personal and environmental factors associated with fruit and vegetable (F&V) and total fat intake in Belgian university students.
In total, 185 students completed a self-reported online questionnaire assessing daily F&V and fat intake, as well as sociodemographic, personal and environmental variables related to F&V and fat intake. Mean F&V and fat consumption were compared with Belgian recommendations. Multiple linear regression analyses were conducted to identify factors associated with F&V and fat intake.
Respectively, 90.3 and 50.8% of students failed to meet the recommendations for F&V and fat consumption. Agreeing more with the fact that one should eat F&V on most days of the week (individual subjective norm), finding it less difficult to eat F&V at home or at university (perceived behavioural control) and experiencing more modelling were associated with higher F&V consumption. Increasing age, higher educational level of the father and higher individual subjective norm about eating low-fat foods were associated with lower fat intake.
Future interventions aiming to improve dietary intake among university students should focus on younger students with lower socioeconomic status and should enhance students' subjective norm and behavioural control concerning healthy eating.
本研究评估了与比利时大学生水果和蔬菜（F&V）及总脂肪摄入相关的社会人口学、一般健康、个人和环境因素。
共有 185 名学生完成了一份自我报告的在线问卷，评估了他们的日常 F&V 和脂肪摄入量，以及与 F&V 和脂肪摄入量相关的社会人口学、个人和环境变量。将 F&V 和脂肪的平均摄入量与比利时的推荐摄入量进行了比较。采用多元线性回归分析来确定与 F&V 和脂肪摄入相关的因素。
分别有 90.3%和 50.8%的学生未能满足 F&V 和脂肪摄入的推荐量。更认同“人们应该在一周的大多数日子里吃 F&V”这一观点（个体主观规范）、认为在家里或在学校吃 F&V 较不难（感知行为控制）、并且受到更多榜样的影响，与更高的 F&V 摄入量有关。年龄增长、父亲的受教育程度较高以及个体对低脂肪食物的主观规范较低，与较低的脂肪摄入量有关。
未来旨在改善大学生饮食摄入的干预措施应针对社会经济地位较低的年轻学生，并应增强学生对健康饮食的主观规范和行为控制。
