The main purpose of the present study was to explore the associations between sleep quality and insufficient physical activity.
Cross-sectional.
Faculties in Croatia.
2100 university students (1049 men and 1051 women) aged 18-24 years were recruited.
To assess the domains of sleep quality (independent variables) and 'insufficient' physical activity (dependent variable), we used previously validated Pittsburgh Sleep Quality Index and International Physical Activity questionnaires. Logistic regressions were used to calculate the associations between the sleep quality and 'insufficient' physical activity.
When sleep quality domains were entered separately into the model, very bad subjective sleep quality (OR 3.09; 95% CI 1.50 to 6.56), >60 min of sleep latency (OR 2.17; 95% CI 1.39 to 3.39), <7 hours of sleep (OR 1.56; 95% CI 1.24 to 1.96), <65% of habitual sleep efficiency (OR 2.26; 95% CI 1.26 to 4.05), sleep disturbances >1/week (OR 1.61; 95% CI 1.03 to 2.52), use of sleep medication >1/week (OR 3.35; 95% CI 1.83 to 6.10), very big daytime dysfunction problem (OR 2.78; 95% CI 1.57 to 4.93) and poor sleep quality (1.53; 95% CI 1.23 to 1.91) were associated with 'insufficient' physical activity. When all sleep quality domains were entered simultaneously into the model, the same significant associations remained, except for sleep disturbances. Both models were adjusted for gender, body mass index, self-rated health, life satisfaction, socioeconomic status, presence or absence of chronic diseases, smoking status, binge drinking and psychological distress.
Our results show that 'poor' sleep quality is associated with 'insufficient' physical activity in young adults. In order to improve, special strategies and policies that leverage 'good sleep' quality are warranted.
本研究的主要目的是探讨睡眠质量与身体活动不足之间的关联。
横断面研究。
克罗地亚的各院系。
招募了2100名年龄在18 - 24岁的大学生（1049名男性和1051名女性）。
为评估睡眠质量（自变量）和“不足的”身体活动（因变量）的各个领域，我们使用了先前经过验证的匹兹堡睡眠质量指数和国际身体活动问卷。采用逻辑回归分析来计算睡眠质量与“不足的”身体活动之间的关联。
当将睡眠质量的各个领域分别纳入模型时，主观睡眠质量非常差（比值比3.09；95%置信区间1.50至6.56）、入睡潜伏期>60分钟（比值比2.17；95%置信区间1.39至3.39）、睡眠时间<7小时（比值比1.56；95%置信区间1.24至1.96）、习惯性睡眠效率<65%（比值比2.26；95%置信区间1.26至4.05）、每周睡眠障碍>1次（比值比1.61；95%置信区间1.03至2.52）、每周使用睡眠药物>1次（比值比3.35；95%置信区间1.83至6.10）、白天功能障碍问题非常严重（比值比2.78；95%置信区间1.57至4.93）以及睡眠质量差（比值比1.53；95%置信区间1.23至1.91）均与“不足的”身体活动相关。当将所有睡眠质量领域同时纳入模型时，除睡眠障碍外，相同的显著关联仍然存在。两个模型均对性别、体重指数、自我评定的健康状况、生活满意度、社会经济地位、是否患有慢性病、吸烟状况、暴饮和心理困扰进行了校正。
我们的结果表明，“差的”睡眠质量与年轻人的“不足的”身体活动相关。为了改善这种情况，需要制定利用“良好睡眠”质量的特殊策略和政策。
