BACKGROUND
College life represents a key transitional period in the life of young adults that is marked by increased social engagement; living habits acquired during this period have implications on the future life of college students. Therefore, investigation of the determinants of health status of college students is a key imperative; however, there is limited evidence on the study of concomitant effects of physical activity (PA), sedentary time (ST), and sleep duration on the health-related quality of life (HRQOL) of college students.
METHODS
This cross-sectional survey was conducted at a medical university in Shenyang in Northeast China in 2017. The study group comprised 926 undergraduate students. Data were collected by a self-administered questionnaire. PA, ST, sleep duration, and HRQOL were measured using the international physical activity questionnaire (IPAQ)-Long Form and the Chinese version of the 12-Item Short-Form Health Survey (SF-12). The association of PA, ST, and sleep duration with the HRQOL was examined using independent t-test, Pearson Chi-squared test, and multivariate linear regression analysis.
RESULTS
After adjusting for potential confounding factors, students who reported high PA had significantly higher physical component summary (PCS) score in the total study population and among female students than those who reported low PA, whereas students who reported moderate PA had significantly higher PCS score only among female students (P < 0.05). In the total study population and among male students, students who slept for ≥9 h/day had significantly higher mental component summary (MCS) score than those who slept for 7-< 8 h/day, whereas among only male students, those who slept for 8-< 9 h/day had significantly higher MCS score (P < 0.05). The interaction term between ST and PA was not statistically significant.
CONCLUSIONS
PA and sufficient sleep duration had a positive impact on the HRQOL of college students; however, ST was not associated with HRQOL and there was no interaction between the impact of ST and PA on the HRQOL of college students. Increasing PA and promoting adequate sleep duration are key health promotion strategies for college students.
背景
大学生活是年轻人生活中的一个关键过渡期，这个时期社交活动增多；在此期间养成的生活习惯对大学生未来的生活有影响。因此，调查大学生健康状况的决定因素是当务之急；然而，关于身体活动（PA）、久坐时间（ST）和睡眠时间对大学生健康相关生活质量（HRQOL）的综合影响的研究证据有限。
方法
本横断面研究于 2017 年在中国东北沈阳的一所医科大学进行。研究组包括 926 名本科学生。数据通过自填式问卷收集。PA、ST、睡眠时间和 HRQOL 通过国际体力活动问卷（IPAQ）-长表和中文版 12 项简明健康调查问卷（SF-12）进行测量。使用独立 t 检验、Pearson 卡方检验和多元线性回归分析评估 PA、ST 和睡眠时间与 HRQOL 的相关性。
结果
在校正了潜在混杂因素后，报告高 PA 的学生在总研究人群和女性学生中，其生理成分综合评分（PCS）显著高于报告低 PA 的学生，而报告中度 PA 的学生仅在女性学生中，其 PCS 评分显著更高（P<0.05）。在总研究人群和男性学生中，每天睡眠时间≥9 小时的学生，其心理成分综合评分（MCS）显著高于每天睡眠时间 7-<8 小时的学生，而仅在男性学生中，每天睡眠时间 8-<9 小时的学生 MCS 评分显著更高（P<0.05）。ST 和 PA 之间的交互项无统计学意义。
结论
PA 和充足的睡眠时间对大学生的 HRQOL 有积极影响；然而，ST 与 HRQOL 无关，ST 和 PA 对大学生 HRQOL 的影响之间没有交互作用。增加 PA 和促进充足的睡眠时间是大学生健康促进的关键策略。
