University students are a vulnerable group for poor dietary intake, insufficient physical activity and sedentary behaviour. The purpose of this study was to examine the impact of coronavirus disease (COVID-19) on university students' dietary intake, physical activity, and sedentary behaviour. Participants were students ( = 125) from the Universities of Saskatchewan and Regina. An online questionnaire was administered retrospectively (for prepandemic) and prospectively (during the pandemic) to examine students' dietary intake, physical activity, and sedentary behaviour. Overall, nutrient and caloric intakes were significantly reduced ( < 0.05) during the pandemic, and alcohol intake increased ( = 0.03). Before the pandemic, 16% and 54% of the participants were meeting the Canadian 24-Hour Movement Guidelines for Adults (18-64 years) of 150 min of moderate-vigorous physical activity and 8 h or less of sedentary activity, respectively. Only 10% met the guidelines for physical activity while 30% met the guidelines for sedentary behaviour during the pandemic. The minutes per week spent engaging in moderate to vigorous physical activity during the pandemic decreased by approximately 20% ( < 0.001). The hours spent in sedentary activities increased by 3 h per day ( < 0.001). Our findings confirm that during the pandemic, students' inadequate dietary intake, high alcohol consumption, low physical activity, and high sedentary behaviour were significantly compounded. During COVID-19, the nutrient and caloric intakes of university students decreased, and alcohol intake increased significantly. University students' physical activity levels decreased, and sedentary activity increased significantly during COVID-19. During COVID-19 students did not engage in sufficient physical activity to offset the increased sedentary behaviour.
大学生群体存在不良饮食摄入、身体活动不足和久坐行为等问题。本研究旨在探讨 2019 冠状病毒病（COVID-19）对大学生饮食摄入、身体活动和久坐行为的影响。参与者为萨斯喀彻温大学和里贾纳大学的学生（n = 125）。采用在线问卷对学生进行回溯性（疫情前）和前瞻性（疫情期间）调查，以评估其饮食摄入、身体活动和久坐行为。总体而言，疫情期间大学生的营养素和热量摄入显著减少（<0.05），而酒精摄入量增加（=0.03）。疫情前，16%和 54%的参与者分别符合加拿大成年人（18-64 岁）24 小时身体活动指南，即中高强度身体活动 150 分钟，久坐行为 8 小时或更少。仅 10%的参与者符合身体活动指南，而 30%的参与者符合疫情期间久坐行为指南。疫情期间，每周中高强度身体活动时间减少了约 20%（<0.001），每天久坐时间增加了 3 小时（<0.001）。研究结果证实，疫情期间学生饮食摄入不足、高酒精摄入、身体活动水平低和久坐行为高的问题进一步恶化。COVID-19 期间，大学生的营养和热量摄入减少，酒精摄入量显著增加。大学生的身体活动水平降低，而 COVID-19 期间久坐行为显著增加。疫情期间学生没有进行足够的身体活动来抵消增加的久坐行为。
