To investigate the independent and combined associations between physical activity and sedentary time with sleep quality among Chinese college students.
A cross-sectional study was conducted among Chinese college students (N = 2347; M age = 20 years; 67.1% students were female). We used the International Physical Activity Questionnaire-Short Form, the Adolescent Sedentary Activity Questionnaire, and the Pittsburgh Sleep Quality Index to assess the subjects' physical activity level, sedentary time, and sleep quality, respectively. Analyses were conducted using a multivariate logistic regression model.
Of the total participants, 48.6% had poor sleep quality and 10% were at low physical activity levels, and the mean (±SD) sedentary time was 5.33 ± 2.34 h/day. No significant association was found between physical activity and sleep quality (OR = 1.27, 95% CI: 0.951.70) among Chinese college students after adjustment for potential confounders. Sedentary time was significantly positively associated with poor sleep quality (OR = 1.37, 95% CI: 1.141.65). The risks for those with a low physical activity level and high sedentary time, and a moderate physical activity level and high sedentary time were 2.78 (OR = 2.78, 95% CI: 1.614.80) and 1.49 (OR = 1.49, 95% CI: 1.131.95) times higher, respectively, than those with a high physical activity level and low sedentary time.
Among Chinese college students, high sedentary time was significantly negatively associated with sleep quality. A low physical activity level was insignificantly associated with sleep quality. A moderate physical activity level and high sedentary time, and a low physical activity level and high sedentary time were interactively associated with increased risks of poor sleep quality, respectively.
探讨中国大学生身体活动和久坐时间与睡眠质量的独立和联合关联。
采用横断面研究，对 2347 名中国大学生（M 年龄=20 岁，67.1%为女生）进行调查。使用国际体力活动问卷-短表、青少年久坐活动问卷和匹兹堡睡眠质量指数分别评估研究对象的体力活动水平、久坐时间和睡眠质量。采用多变量 logistic 回归模型进行分析。
在所有参与者中，48.6%的人睡眠质量较差，10%的人身体活动水平较低，平均（±SD）久坐时间为 5.33±2.34 h/d。在调整潜在混杂因素后，中国大学生的身体活动与睡眠质量之间无显著关联（OR=1.27，95%CI：0.951.70）。久坐时间与睡眠质量差呈显著正相关（OR=1.37，95%CI：1.141.65）。低身体活动水平和高久坐时间，以及中身体活动水平和高久坐时间的个体发生睡眠质量差的风险分别是高身体活动水平和低久坐时间个体的 2.78 倍（OR=2.78，95%CI：1.614.80）和 1.49 倍（OR=1.49，95%CI：1.131.95）。
在中国大学生中，高久坐时间与睡眠质量显著负相关。低身体活动水平与睡眠质量无显著关联。中身体活动水平和高久坐时间，以及低身体活动水平和高久坐时间分别与睡眠质量差的风险增加呈交互关联。
