University science students who have taken a nutrition course possess greater knowledge of fats than do those who have not; whether students apply this knowledge to their diet is unknown. We measured and compared science students' total and saturated fat intake in the first and fourth years, and evaluated whether taking a nutrition course influenced fat consumption.
A sample of 269 first- and fourth-year science students at a small undergraduate university completed a survey with both demographic questions and a semi-quantitative food frequency questionnaire about fats in the diet. Data were analyzed using chi-square tests and independent-sample t-tests.
Fourth-year science students consumed fewer grams of total and saturated fat than did first-year science students (p<0.001). Science students who had taken a nutrition course consumed fewer grams of total and saturated fat than did those who had not (p<0.001).
Taking a nutrition course may decrease first-year students' fat consumption, which may improve diet quality and decrease the risk of chronic disease related to fat consumption.
修过营养课程的大学生比未修过的学生对脂肪有更多了解;但学生是否将这些知识应用到饮食中尚不清楚。我们测量并比较了理科学生一年级和四年级时的总脂肪摄入量和饱和脂肪摄入量,并评估修读营养课程是否会影响脂肪摄入。
一所小型本科院校的269名一年级和四年级理科学生样本完成了一项调查,其中包括人口统计学问题以及一份关于饮食中脂肪的半定量食物频率问卷。数据采用卡方检验和独立样本t检验进行分析。
四年级理科学生的总脂肪和饱和脂肪摄入量低于一年级理科学生(p<0.001)。修过营养课程的理科学生的总脂肪和饱和脂肪摄入量低于未修过的学生(p<0.001)。
修读营养课程可能会降低一年级学生的脂肪摄入量,这可能会改善饮食质量,并降低与脂肪摄入相关的慢性病风险。
