Tertiary education institutions have been linked with excessive weight in young adults. However, few data are available on the effect of foods from the university food environment on the diet quality of young adults. The aim of this study was to describe the association of a number of foods and beverages consumed at university food outlets with the diet quality of young adults.
This was a cross-sectional survey in which the 103 university student participants, aged 19 to 24 y, contributed 5 d of dietary data. A purposely designed, validated smartphone application was used to collect the data. Diet quality was assessed by adherence to the 2013 dietary guidelines for food groups and nutrients, and the validated Healthy Eating Index for Australians (HEIFA-2013) was applied. Individual HEIFA-2013 scores were compared with the frequency of food purchase and consumption from university outlets to assess a dose-response effect of the food environment. Comparisons by tertiles of diet quality for body mass index, waist circumference, and takeaway food consumption (university and other) were computed using a one-way analysis of variance and post hoc Tukey test.
There was a statistically significant difference between the number of university foods and beverages consumed in 5 d and the HEIFA-2013 scores: More on-campus purchases resulted in a poor-quality diet (P = 0.001). As the HEIFA-2013 tertile scores increased, there was a significant decrease in the number of university campus and other takeaway foods consumed; body mass index and waist circumference showed a decrease in trend.
Efforts to improve the diet quality of young adults attending university may benefit from approaches to improve the campus food environment.
高等教育机构与年轻人超重问题有关联。然而，关于大学饮食环境中的食物对年轻人饮食质量影响的数据却很少。本研究的目的是描述在大学食品店消费的多种食品和饮料与年轻人饮食质量之间的关联。
这是一项横断面调查，103名年龄在19至24岁的大学生参与者提供了5天的饮食数据。使用专门设计并经验证的智能手机应用程序收集数据。通过遵循2013年食物组和营养素膳食指南来评估饮食质量，并应用经过验证的澳大利亚健康饮食指数（HEIFA - 2013）。将个体的HEIFA - 2013得分与从大学食品店购买和消费食物的频率进行比较，以评估饮食环境的剂量反应效应。使用单因素方差分析和事后Tukey检验，按饮食质量三分位数对体重指数、腰围和外卖食品消费（大学及其他）进行比较。
5天内消费的大学食品和饮料数量与HEIFA - 2013得分之间存在统计学显著差异：更多的校内购买导致饮食质量较差（P = 0.001）。随着HEIFA - 2013三分位数得分增加，大学食堂和其他外卖食品的消费数量显著减少；体重指数和腰围呈下降趋势。
改善上大学的年轻人的饮食质量，可通过改善校园饮食环境的方法来实现。
