Abstract

In this study, we estimated the impact of COVID-19 on physical activity (PA) for Chinese university students during the pandemic period. The International Physical Activity Questionnaire was completed online by 1487 students (947 males and 513 females; age 19.72 ± 1.32 years, BMI = 21.12 ± 4.50) from one university in China during the pandemic period, and students retrospectively recalled pre-pandemic PA levels (March 29- April 15, 2020). We analyzed the data using a paired-samples t-test. Overall, COVID-19 produced a 27.89% reduction in total weekly minutes (40.62) of vigorous PA, a 43.38% reduction in total weekly minutes (73.92) of moderate PA, and a 24.36% reduction in total weekly minutes of walking (44.69). Results by sex showed that moderate PA decreased the most, by 47.15% (males) and 37.13% (females), and total PA decreased by 48.29% (males) and 40.18% (females). COVID-19 led to a reduction in PA among Chinese university students. PA decreased more for male than female students. Public policy action might be needed to increase the level of PA of Chinese university students.

摘要

在这项研究中，我们估计了 COVID-19 对中国大学生在疫情期间的身体活动（PA）的影响。共有 1487 名学生（947 名男性和 513 名女性；年龄 19.72±1.32 岁，BMI=21.12±4.50）通过在线填写了国际身体活动问卷，这些学生来自中国的一所大学，调查时间是在疫情期间，学生们回顾了疫情前的 PA 水平（2020 年 3 月 29 日至 4 月 15 日）。我们使用配对样本 t 检验分析了数据。总的来说，COVID-19 导致大学生每周剧烈 PA 总分钟数减少了 27.89%（40.62 分钟），每周中等强度 PA 总分钟数减少了 43.38%（73.92 分钟），每周步行总分钟数减少了 24.36%（44.69 分钟）。按性别分析的结果显示，中等强度 PA 减少最多，男性减少 47.15%，女性减少 37.13%，总 PA 减少 48.29%（男性）和 40.18%（女性）。 COVID-19 导致中国大学生 PA 减少。男性学生的 PA 减少比女性学生更多。可能需要采取公共政策行动来提高中国大学生的 PA 水平。
