This study aimed to reveal the key lifestyle elements that improve physical and mental health in university students by focusing on physical activity, nutrition, and sleep. This cross-sectional study was conducted between October 2021 and December 2021. The participants were 290 first-year students (mean age, 18.63 ± .63 years; age range, 18 to 23; 198 female). The outcomes were daily step counts measured using accelerometers, dietary intake by nutrient category, sleep duration, subjective sleep quality, exercise frequency and duration by exercise type, screen time, depression level, and subjective fatigue by body part. Depression and subjective eye fatigue represent mental and physical health outcomes. Subjective sleep quality predicted depression (β = -1.22, < .001) and eye fatigue (β = -.23, < .01) in the path analysis. Participants with higher subjective sleep quality performed more frequent aerobic exercise ( < .01), longer session times of physical relaxation exercise ( < .05), and shorter screen time ( < .05). Subjective sleep quality could be a key factor for high mental and physical health. Furthermore, performing aerobic and relaxation exercises and reducing screen time are important for improving the subjective sleep quality.
本研究旨在通过关注体育活动、营养和睡眠，揭示改善大学生身心健康的关键生活方式要素。这项横断面研究于2021年10月至2021年12月进行。参与者为290名一年级学生（平均年龄18.63±0.63岁；年龄范围18至23岁；198名女性）。研究结果包括使用加速度计测量的每日步数、按营养类别划分的饮食摄入量、睡眠时间、主观睡眠质量、按运动类型划分的运动频率和时长、屏幕使用时间、抑郁水平以及身体各部位的主观疲劳程度。抑郁和主观眼部疲劳代表身心健康结果。在路径分析中，主观睡眠质量可预测抑郁（β=-1.22，P<0.001）和眼部疲劳（β=-0.23，P<0.01）。主观睡眠质量较高的参与者进行有氧运动的频率更高（P<0.01）、身体放松运动的时长更长（P<0.05）且屏幕使用时间更短（P<0.05）。主观睡眠质量可能是身心健康的关键因素。此外，进行有氧运动和放松运动以及减少屏幕使用时间对于提高主观睡眠质量很重要。
