To examine fruit and vegetable intake and self-efficacy among U.S. college students in a rural, Southern location. Undergraduate students ( = 1503) enrolled in a university-wide health class at one large public institution during the spring 2017 semester. Cross-sectional survey data were collected online and analyzed using independent samples test, one-way ANOVA, and regression. On average, participants did not meet fruit or vegetable intake recommendations. Mean self-efficacy scores were 17.2 ( = 3.4) and 16.42 ( = 3.7) for fruit and vegetables, respectively, with statistically significant differences observed by sex and race ( < 0.05). Hierarchical multiple regression results indicated self-efficacy explained 20.9% (fruit) and 29.3% (vegetables) of the variance in consumption. Similar patterns were found for meeting daily fruit and vegetable intake recommendations. Health campaigns are needed to address sex and racial disparities in college student fruit and vegetable intake and self-efficacy.
调查美国南方农村地区大学生的水果和蔬菜摄入量及自我效能感。2017 年春季学期，在一所大型公立大学的全校健康课程中，对 1503 名本科生进行了横断面调查。在线收集调查数据，并采用独立样本 t 检验、单因素方差分析和回归分析进行分析。平均而言，参与者的水果和蔬菜摄入量未达到推荐量。水果和蔬菜自我效能感的平均得分分别为 17.2（=3.4）和 16.42（=3.7），性别和种族间存在统计学差异（<0.05）。分层多元回归结果表明，自我效能感解释了水果摄入量（20.9%）和蔬菜摄入量（29.3%）差异的 20.9%和 29.3%。对于达到每日水果和蔬菜摄入量建议的情况，也发现了类似的模式。需要开展健康宣传活动，以解决大学生水果和蔬菜摄入量及自我效能感方面的性别和种族差异。
