The objectives of this study were to examine in university students: (a) the mean differences in the HRQoL among fat mass percentage, cardiorespiratory fitness (CRF) and sleep quality categories; and (b) the independent associations among fat mass percentage, CRF, and sleep quality with HRQoL.
376 students, 18-30 years old, from the University of Castilla-La Mancha in Cuenca, Spain (during 2009-2010).
Cross-sectional study measuring % fat mass (DXA), CRF (20-m shuttle run test), sleep quality (Pittsburgh Sleep Quality Index), and HRQoL (SF-12 questionnaire).
The mean in Mental Component Summary (MCS) in men (p = .029) was lower in students in upper quartiles of % fat mass than in peers in other categories of % fat mass. Among men, MCS was significantly lower among those in the lowest quartile of CRF (p = .015), and among women, Physical Component Summary (PCS) was significantly lower among those in the lowest quartile of CRF (p = .047). MCS dimension of the HRQoL was lower in both men (p = .001) and women (p < .001) in upper quartiles of sleep quality. Multiple linear regression models showed that in men, CRF was associated with MCS (β = 0.25, p = .031), and sleep quality was associated with PCS (β = -0.24, p = .027) and MCS (β = -0.38, p < .001). In women, CRF was associated with PCS (β = 0.17, p = .018) and sleep quality with MCS (β= -0.44, p < .001).
Finally, our findings suggest that, regardless of adiposity and fitness, having good sleep habits may positively influence the quality of life in young adults.
本研究旨在考察大学生群体中：（a）体脂百分比、心肺适能（CRF）和睡眠质量类别之间的 HRQoL 的平均差异；（b）体脂百分比、CRF 和睡眠质量与 HRQoL 之间的独立关联。
376 名 18-30 岁的学生，来自西班牙卡斯蒂利亚-拉曼恰大学昆卡分校（2009-2010 年）。
横断面研究测量体脂百分比（DXA）、CRF（20 米穿梭跑测试）、睡眠质量（匹兹堡睡眠质量指数）和 HRQoL（SF-12 问卷）。
男性的心理成分综合得分（MCS）平均值（p =.029）在体脂百分比处于较高四分位的学生中低于其他体脂百分比类别的同龄人。在男性中，CRF 处于最低四分位的 MCS 显著降低（p =.015），而在女性中，CRF 处于最低四分位的 PCS 显著降低（p =.047）。在男性（p =.001）和女性（p <.001）中，HRQoL 的 MCS 维度在睡眠质量处于较高四分位的人群中较低。多元线性回归模型显示，在男性中，CRF 与 MCS 相关（β=0.25，p =.031），而睡眠质量与 PCS（β= -0.24，p =.027）和 MCS（β= -0.38，p <.001）相关。在女性中，CRF 与 PCS 相关（β=0.17，p =.018），而睡眠质量与 MCS 相关（β= -0.44，p <.001）。
最后，我们的研究结果表明，无论肥胖和体能如何，良好的睡眠习惯可能会对年轻人的生活质量产生积极影响。
