Abstract：
UNASSIGNED: Food insecurity is a pivotal determinant of health outcomes. Little evidence exists on the association between food insecurity and health behaviors and outcomes, including diet quality, among graduate students or postdoctoral trainees.
UNASSIGNED: This study aimed to examine the association between food insecurity and diet quality among graduate students and postdoctoral trainees at 3 health-focused graduate schools (public health, medical, and dental medicine) within Harvard University.
UNASSIGNED: Between April and June 2023, 1287 graduate students and 458 postdoctoral trainees at the health-focused schools within Harvard University completed a web-based survey. The primary exposure was food security status, assessed using the United States Household Food Security Survey Module. The primary outcome was diet quality, measured using the 30-day Prime Diet Quality Score screener (ranges from 0 to 126, with higher scores indicating healthier diets). The associations between food insecurity and diet quality were examined using multivariable regression models, adjusting for sociodemographic covariates.
UNASSIGNED: Among graduate students, compared with those with high food security, diet quality was significantly lower among those experiencing marginal food security [β: -4.7; 95% confidence interval (CI): -6.5, -2.9], low food security (β: -5.4; 95% CI: -7.6, -3.3), and very low food security (β: -4.4; 95% CI: -7.4, -1.4). Poor diet quality included lower intake frequencies of vegetables, fruits, beans/peas/soy products, nuts/seeds, poultry, fish, low-fat dairy, and liquid oils, and higher intake frequencies of refined grains/baked products, sugar-sweetened beverages, and fried foods. Among postdoctoral trainees, compared with those with high food security, diet quality was significantly lower among those experiencing low food security (β: -5.1; 95% CI: -8.8, -1.4), and very low food security (β: -5.2; 95% CI: -10.2, -0.2). Poor diet quality included lower intake frequencies of dark green leafy vegetables, other fruits, and whole grains.
UNASSIGNED: Graduate students and postdoctoral trainees who experienced degrees of food insecurity reported lower diet quality. These observations underscore the need for policies and interventions to simultaneously reduce food insecurity and improve diet quality.

摘要：
■粮食不安全是健康结果的关键决定因素。关于粮食不安全与健康行为和结果之间的关联的证据很少，包括饮食质量，在研究生或博士后学员中。
■本研究旨在研究3所以健康为重点的研究生院（公共卫生，medical,和牙科医学）在哈佛大学内。
在2023年4月至6月之间，哈佛大学以健康为重点的学校的1287名研究生和458名博士后学员完成了一项基于网络的调查。主要暴露于食品安全状况,使用美国家庭食品安全调查模块进行评估。主要结果是饮食质量，使用30天主要饮食质量评分筛选器测量（范围从0到126，较高的分数表明更健康的饮食）。使用多变量回归模型检查了粮食不安全与饮食质量之间的关联，调整社会人口统计学协变量。
■在研究生中，与那些具有高粮食安全的人相比，在经历边际粮食安全的人群中，饮食质量明显较低[β：-4.7；95%置信区间（CI）：-6.5，-2.9]，低粮食安全(β：-5.4；95%CI：-7.6，-3.3)，和非常低的粮食安全（β：-4.4；95%CI：-7.4，-1.4）。饮食质量差包括蔬菜的摄入频率较低，水果,豆类/豌豆/豆制品，坚果/种子，家禽,鱼,低脂乳制品，和液体油，以及更高的精制谷物/烘焙产品的摄入频率，含糖饮料,和油炸食品。在博士后学员中，与那些具有高粮食安全的人相比，饮食质量在食品安全低的人群中明显较低(β：-5.1；95%CI：-8.8，-1.4)，和非常低的粮食安全(β：-5.2；95%CI：-10.2，-0.2)。饮食质量差包括深绿色叶类蔬菜的摄入频率较低，其他水果,和全谷物。
■经历过粮食不安全程度的研究生和博士后学员报告说饮食质量较低。这些观察结果强调，需要采取政策和干预措施，同时减少粮食不安全和提高饮食质量。
