This study aimed to investigate the associations of physical activity (PA) and screen time (ST) with physiological, psychological, and social health-particularly regarding effects on sleep quality-among Chinese college freshmen. A cross-sectional survey was conducted at Renmin University of China, in Beijing. A total of 5,233 students were surveyed in September 2015. Participants completed a self-report questionnaire on their demographic characteristics, tobacco and alcohol use, PA, ST, sleep quality, and health status. Multivariate logistic regression was performed to examine the independent and interactive associations between PA and ST with sleep quality and suboptimal health status. In total, 10.43%, 13.18%, and 13.26% of the 5,233 students had physiological, psychological, and social suboptimal health status, respectively. The prevalence of poor sleep quality was 37.94%. High ST and high PA were significantly associated with physiological suboptimal health status (aOR = 1.39, 95% CI: 1.16-1.68, and aOR = 0.55, 95% CI: 0.45-0.71), psychological suboptimal health status (aOR = 1.43, 95% CI: 1.21-1.69, and aOR = 0.57, 95% CI: 0.47-0.69), social suboptimal health status (aOR = 1.27, 95% CI: 1.08-1.50, and aOR = 0.63, 95% CI: 0.52-0.77), and poor sleep quality (aOR = 1.20, 95% CI: 1.03-1.39, and aOR = 0.64, 95% CI: 0.55-0.76). Additionally, low ST and high PA were interactively negatively associated with poor sleep quality (aOR = 0.56, 95% CI: 0.45-0.70), physiological suboptimal health status (aOR = 0.49, 95% CI: 0.40-0.59), psychological suboptimal health status (aOR = 0.48, 95% CI: 0.39-0.58), and social suboptimal health status (aOR = 0.49, 95% CI: 0.40-0.59). These findings suggested there are independent and interactive associations of low ST and high PA with poor sleep quality and suboptimal health status among Chinese college freshmen.
这项研究旨在调查身体活动（PA）和屏幕时间（ST）与生理、心理和社会健康的关联，尤其是对睡眠质量的影响，研究对象为中国大学新生。该研究在北京的中国人民大学进行了一项横断面调查。2015 年 9 月，共有 5233 名学生参与了调查。参与者完成了一份关于人口统计学特征、烟草和酒精使用、PA、ST、睡眠质量和健康状况的自我报告问卷。采用多变量逻辑回归分析 PA 和 ST 与睡眠质量和亚健康状况之间的独立和交互关联。在 5233 名学生中，分别有 10.43%、13.18%和 13.26%的学生生理、心理和社会亚健康状况较差。睡眠质量差的患病率为 37.94%。高 ST 和高 PA 与生理亚健康状况显著相关（OR = 1.39，95%CI：1.16-1.68 和 OR = 0.55，95%CI：0.45-0.71），与心理亚健康状况显著相关（OR = 1.43，95%CI：1.21-1.69 和 OR = 0.57，95%CI：0.47-0.69），与社会亚健康状况显著相关（OR = 1.27，95%CI：1.08-1.50 和 OR = 0.63，95%CI：0.52-0.77），与睡眠质量差显著相关（OR = 1.20，95%CI：1.03-1.39 和 OR = 0.64，95%CI：0.55-0.76）。此外，低 ST 和高 PA 之间存在交互作用，与睡眠质量差（OR = 0.56，95%CI：0.45-0.70）、生理亚健康状况（OR = 0.49，95%CI：0.40-0.59）、心理亚健康状况（OR = 0.48，95%CI：0.39-0.58）和社会亚健康状况（OR = 0.49，95%CI：0.40-0.59）显著负相关。这些发现表明，低 ST 和高 PA 与中国大学新生的睡眠质量差和亚健康状况存在独立和交互关联。
