Abstract

Purpose: Given the high prevalence of food insecurity among college students, there is an interest in identifying whether the use of a single item can adequately screen for food insecurity. The current study aimed to determine the validity of a single-item food insecurity screening question among college students.

Design: Cross-sectional study exploring food insecurity among racial and ethnic undergraduate college students.

Setting: Large urban U.S. research university.

Sample: Undergraduate students (n = 667) 18 years or older.

Measures: Food Insecurity screening was assessed via a single-item from the USDA Household Food Security Short Form (USDA FSSM-SF). Food security was assessed via the USDA FSSM-SF, a validated six-item scale that assesses food insecurity and hunger.

Analysis: Logistic regression assessed the validity of the single-item food insecurity question tested against the USDA FSSM-SF.

Results: The full model was statistically significant, χ2(1) = 161.44, P < .001 explaining 54.5% of the variance in food insecurity status correctly classifying 95.7% of cases. Sensitivity of the model was found to be 97.6%; specificity was found to be 69.6%. Positive predictive value was calculated to be 97.74%; negative predictive value was computed to be 68.09%.

Conclusion: Results support for the test validity of a single-item screening question that can be used to detect food insecurity among college students and inform secondary prevention programs aimed at food insecurity.

大学生单项食物不安全筛查评估的测试有效性。

目的：鉴于大学生中粮食不安全的发生率很高，人们有兴趣确定使用单一项目是否能够充分筛查粮食不安全。本研究旨在确定大学生中单项食物不安全筛查问题的有效性：设计：横断面研究，探讨不同种族和族裔本科大学生的食物不安全问题：地点：美国大型城市研究型大学：测量方法：食物不安全筛查是通过一个名为 "食物安全"（Food Insecurity）的问卷进行评估的：食物不安全筛查通过美国农业部家庭食物安全简表（USDA FSSM-SF）中的一个单项进行评估。食物安全通过 USDA FSSM-SF 进行评估，这是一个经过验证的六项目量表，用于评估食物不安全和饥饿情况：逻辑回归评估了根据 USDA FSSM-SF 测试的单项食品不安全问题的有效性：完整模型具有统计学意义，χ2(1) = 161.44，P < .001 解释了食物不安全状况 54.5% 的变异，正确分类了 95.7% 的案例。该模型的灵敏度为 97.6%，特异度为 69.6%。阳性预测值为 97.74%，阴性预测值为 68.09%：结果支持单项筛查问题的测试有效性，该问题可用于检测大学生的粮食不安全状况，并为针对粮食不安全状况的二级预防计划提供信息。
