Abstract

Background

The high prevalence of food insecurity in college students is a pressing issue. Increasing nutrition knowledge has potential to help improve factors related to food security. While a positive correlation between food literacy and food security status has been reported, little research has explored the impact of an existing college-level nutrition class.

Objective

To investigate how a college-level nutrition course impacts behaviors related to food-acquisition coping strategies.

Study Design, Settings, Participants

Students at the University of California, Davis were recruited from an introductory nutrition course taught both online and in-person (intervention) and other introductory courses (comparison). Students completed a pre-survey within the first two weeks of the quarter and a post-survey eight weeks later. Data were collected using a 65-item questionnaire that included several validated modules: the Money Expenditure Survey (MES), Coping Strategy Scale (CSS), Perceived Stress Scale, nutrition knowledge survey, and the USDA Adult Food Security Survey Module.

Measurable Outcome/Analysis

ANOVA with Tukey post-hoc corrections was used to assess differences across groups using STATA 13.0v. Significance was determined using p<0.05.

Results

Nutrition knowledge significantly increased within the in-person intervention group (n=282; 1.18 ± 5.24; p<0.01), and the online intervention group (n=373; 1.69 ± 5.12; p<0.01), while nutrition knowledge decreased in the comparison group (n=304; -1.41 ± 3.82 p<0.01). The CSS score significantly improved in the online intervention group (-2.62 ± 12.18; p<0.01), as compared to the other groups. In all groups, more students reported experiencing low or very low food security status from pre to post, with significant changes observed in the in-person intervention and comparison groups. Perceived stress also increased across all groups (p<0.05). There were no differences across groups in MES.

Conclusions

Although nutrition knowledge improved in the intervention groups and CSS improved in the online intervention group, food security status decreased and perceived stress increased. Further analyses will determine the importance of nutrition knowledge on MES and CSS and their relationship to temporal fluctuations in food security status.

了解大学营养课程如何影响粮食安全状况
背景大学生普遍存在食物不安全问题,这是一个亟待解决的问题。增加营养知识有可能有助于改善与食品安全相关的因素。研究设计、设置、参与者加利福尼亚大学戴维斯分校的学生是从一门在线和面对面授课的营养学入门课程(干预)和其他入门课程(对比)中招募的。学生们在本季度的前两周内完成了前调查,并在八周后完成了后调查。数据收集采用 65 项调查问卷,其中包括几个经过验证的模块:金钱支出调查 (MES)、应对策略量表 (CSS)、感知压力量表、营养知识调查和美国农业部成人食品安全调查模块。结果当面干预组(n=282;1.18 ± 5.24;p<0.01)和在线干预组(n=373;1.69 ± 5.12;p<0.01)的营养知识显著增加,而对比组(n=304;-1.41 ± 3.82 p<0.01)的营养知识有所减少。与其他组相比,在线干预组的 CSS 分数明显提高(-2.62 ± 12.18; p<0.01)。在所有组别中,有更多的学生报告说,从干预前到干预后,他们的食品安全状况处于较低或非常低的水平,在面对面干预组和对比组中观察到了明显的变化。所有组别中,感知到的压力也都有所增加(p<0.05)。结论虽然干预组的营养知识有所改善,在线干预组的 CSS 有所改善,但粮食安全状况有所下降,感知压力有所上升。进一步的分析将确定营养知识对 MES 和 CSS 的重要性,以及它们与粮食安全状况的时间波动之间的关系。

期刊介绍: The Journal of Nutrition Education and Behavior (JNEB), the official journal of the Society for Nutrition Education and Behavior, is a refereed, scientific periodical that serves as a global resource for all professionals with an interest in nutrition education; nutrition and physical activity behavior theories and intervention outcomes; complementary and alternative medicine related to nutrition behaviors; food environment; food, nutrition, and physical activity communication strategies including technology; nutrition-related economics; food safety education; and scholarship of learning related to these areas. The purpose of JNEB is to document and disseminate original research and emerging issues and practices relevant to these areas worldwide. The Journal of Nutrition Education and Behavior welcomes evidence-based manuscripts that provide new insights and useful findings related to nutrition education research, practice and policy. The content areas of JNEB reflect the diverse interests in nutrition and physical activity related to public health, nutritional sciences, education, behavioral economics, family and consumer sciences, and eHealth, including the interests of community-based nutrition-practitioners. As the Society''s official journal, JNEB also includes policy statements, issue perspectives, position papers, and member communications.
