Significant levels of physical activity (PA) have benefit in reducing chronic diseases in the general adults, but little is known on the association between health-related quality of life (HRQoL) and PA levels among young population. This study aims to investigate the association between different levels of PA and HRQoL in a random sample of 155 Italian University students (age range: 18-30 years old).
We used the short version of IPAQ and SF-36 to assess PA levels and HRQoL, respectively. Differences in HRQoL scores between the three IPAQ categories (low, moderate and high) were evaluated by the analysis of covariance (with age and BMI as covariates). Forward stepwise multiple regression analysis was used to determine the most predictive variables for a good HRQoL.
A significant relationship between PA (Kcal/week and METs/week) and Physical Functioning, Role Physical, General Health, and Physical Summary Component scores was observed in women, while the Role Physical, and the Vitality were associated with PA in men. The amount of PA (day/week, Kcal/week and METs/week) significantly predicted the HRQoL scores and the variance explained by the function ranged from 5.75% to 14.24% for women and from 5.41% to 10.95% for men. The regular frequency of PA during the week was the most important positive predictors for the highest scores in most of HRQoL domains.
Our results confirm that the highest PA Levels were associated with more favorable scores in HRQoL dimensions, also among young Italian population.
大量的体育活动对降低普通成年人的慢性病风险有益，但对于年轻人群中健康相关生活质量（HRQoL）与体育活动水平之间的关联，我们却知之甚少。本研究旨在调查155名意大利大学生（年龄范围：18 - 30岁）的随机样本中，不同体育活动水平与HRQoL之间的关联。
我们分别使用国际体力活动问卷简版（IPAQ）和简明健康调查量表（SF - 36）来评估体育活动水平和HRQoL。通过协方差分析（以年龄和体重指数作为协变量）评估IPAQ三个类别（低、中、高）之间HRQoL得分的差异。采用向前逐步多元回归分析来确定HRQoL良好的最具预测性的变量。
在女性中，观察到体育活动（千卡/周和代谢当量/周）与身体功能、身体角色功能、总体健康和身体综合得分之间存在显著关系，而在男性中，身体角色功能和活力与体育活动相关。体育活动量（天/周、千卡/周和代谢当量/周）显著预测了HRQoL得分，该函数解释的方差在女性中为5.75%至14.24%，在男性中为5.41%至10.95%。一周内体育活动的规律频率是大多数HRQoL领域中得分最高的最重要的正向预测因素。
我们的结果证实，即使在年轻的意大利人群中，最高的体育活动水平也与HRQoL维度中更有利的得分相关。
