2019 年冠状病毒病 (COVID-19) 大流行导致世界许多地区采取了物理隔离措施。在澳大利亚，全国范围内的限制包括呆在家里，除非寻求医疗护理、提供护理、购买食物、进行锻炼或参加基本服务工作。所有本科大学课程都转向在线学习，大部分是在家学习。因此，我们研究了澳大利亚 COVID-19 大流行早期（3 月/4 月）隔离措施对生物医学三年级学生的饮食（24 小时回忆）和身体活动（活跃澳大利亚调查）模式的影响。研究结果与前两年就读同一课程的学生进行了比较。与 2018 年和 2019 年相比，女性（而非男性）的能量摄入量增加了约 20%，吃零食的频率和消耗零食的能量密度也有所增加。在大流行期间，男女的体育活动都受到了影响，与前两年相比，达到“足够”活动水平（定义为至少 5 节课中至少 150 分钟）的学生减少了约 30%。在六到八周后的一项后续研究中（回复率为 14-18%），在全国范围内逐渐放松限制的过程中，尽管健身房继续关闭和在线学习，但女性的能量摄入量较高，男女体力活动水平仍然较低。这些数据证明了隔离措施对健康的影响，并有可能影响长期的饮食和活动行为。
The coronavirus disease 2019 (COVID-19) pandemic resulted in physical isolation measures in many parts of the world. In Australia, nationwide restrictions included staying at home, unless seeking medical care, providing care, purchasing food, undertaking exercise, or attending work in an essential service. All undergraduate university classes transitioned to online, mostly home-based learning. We, therefore, examined the effect of isolation measures during the early phase of the COVID-19 pandemic in Australia (March/April) on diet (24-h recall) and physical activity (Active Australia Survey) patterns in third-year biomedical students. Findings were compared with students enrolled in the same course in the previous two years. In females, but not males, energy intake was similar to 20% greater during the pandemic, and snacking frequency and energy density of consumed snacks also increased compared with 2018 and 2019. Physical activity was impacted for both sexes during the pandemic with similar to 30% fewer students achieving "sufficient" levels of activity, defined by at least 150 min over at least five sessions, compared with the previous two years. In a follow-up study six to eight weeks later (14-18% response rate), during gradual easing of nationwide restrictions albeit continued gym closures and online learning, higher energy intake in females and reduced physical activity levels in both sexes persisted. These data demonstrate the health impacts of isolation measures, with the potential to affect long-term diet and activity behaviours.
