To examine the independent, joint, and fully combined associations of sedentary behavior (SB), moderate-to-vigorous physical activity (MVPA), and cardiorespiratory fitness (CRF) with the odds of poor sleep quality (SQ).
We performed a secondary data analysis on 757 working adults (male = 345) in Singapore, with an average age of 35.2 years. The Pittsburgh Sleep Quality Index was used to assess SQ. Objectively measured MVPA and SB were each obtained using an accelerometer. A non-exercise prediction equation was used to estimate CRF. Logistic regression models were used to determine associations.
In total, 13.2% of the sample (n = 100) was identified as having poor SQ. After adjusting for study covariates, independent analyses revealed a clear inverse association for higher CRF and lower odds of poor SQ (OR = 0.50; 95% CI = 0.28-0.91). SB and MVPA demonstrated no independent associations. Joint associations revealed that odds of having poor SQ for those with low CRF was higher regardless of SB level and was further deteriorated by lower MVPA in the fully combined model. The fully combined model also demonstrated that those with lower SB, higher MVPA, and higher CRF had the lowest odds of having poor SQ (OR = 0.28; 95% CI = 0.10-0.78).
Physical activity/exercise training programs that aim to improve CRF may be useful in lowering the odds or poor SQ in working adults.
研究久坐行为（SB）、中等至剧烈体力活动（MVPA）和心肺适能（CRF）与睡眠质量差（SQ）的几率之间独立、联合和完全联合的关联。
我们对新加坡 757 名在职成年人（男性=345）进行了二次数据分析，平均年龄为 35.2 岁。使用匹兹堡睡眠质量指数评估 SQ。使用加速度计分别测量客观测量的 MVPA 和 SB。使用非运动预测方程估计 CRF。使用逻辑回归模型确定关联。
在总样本中，有 13.2%（n=100）的人被确定为睡眠质量差。在调整研究协变量后，独立分析显示，CRF 较高与睡眠质量差的几率较低呈明显负相关（OR=0.50；95%CI=0.28-0.91）。SB 和 MVPA 没有独立的关联。联合分析显示，无论 SB 水平如何，CRF 较低的人睡眠质量差的几率较高，在完全联合模型中，MVPA 较低会进一步恶化。完全联合模型还表明，那些 SB 水平较低、MVPA 水平较高、CRF 水平较高的人睡眠质量差的几率最低（OR=0.28；95%CI=0.10-0.78）。
旨在提高 CRF 的体育活动/锻炼训练计划可能有助于降低在职成年人睡眠质量差的几率。
