BACKGROUND/AIM: We evaluated the association between leisure time physical activity (PA) and quality of life (QoL) in medical students. Our hypothesis was that there was a positive association between volume of PA and various domains of perception of QoL.
Data were evaluated from a random sample of 1350 medical students from 22 Brazilian medical schools. Information from participants included the WHO Quality of Life questionnaire-short form (WHOQOL-BREF), a questionnaire specifically designed to evaluate QoL in medical students (VERAS-Q) and questions for both global QoL self-assessment and leisure time PA. According to the amount of metabolic equivalents (METs) spend during PA, volunteers were divided into four groups, according to the volume of PA: (a) no PA; (b) low PA, ≤540 MET min/week; (c) moderate PA, from 541 to 1260 MET min/week and (d) high PA, > 1261 MET min/week.
Forty per cent of the medical students reported no leisure time PA (46.0% of females and 32.3% of males). In contrast, 27.2% were classified in the group of high PA (21.0% of females and 34.2% of males). We found significant associations between moderate and high levels of PA and better QoL for all measurements. For low levels of PA, this association was also significant for most QoL measurements, with the exceptions of WHOQOL physical health (p=0.08) and social relationships (p=0.26) domains.
We observed a strong dose-effect relationship between the volume of leisure time PA and QoL in both male and female medical students.
背景/目的：我们评估了医学生休闲时间身体活动（PA）与生活质量（QoL）之间的关联。我们的假设是，PA量与QoL感知的各个领域之间存在正相关。
对来自巴西22所医学院的1350名医学生的随机样本数据进行评估。参与者的信息包括世界卫生组织生活质量简表（WHOQOL-BREF）、专门设计用于评估医学生生活质量的问卷（VERAS-Q）以及关于整体生活质量自我评估和休闲时间PA的问题。根据PA期间消耗的代谢当量（METs）量，志愿者根据PA量分为四组：（a）无PA；（b）低PA，≤540 MET分钟/周；（c）中等PA，541至1260 MET分钟/周；（d）高PA，>1261 MET分钟/周。
40%的医学生报告没有休闲时间PA（女性为46.0%，男性为32.3%）。相比之下，27.2%被归类为高PA组（女性为21.0%，男性为34.2%）。我们发现，中等和高水平的PA与所有测量的更好生活质量之间存在显著关联。对于低水平的PA，除了WHOQOL身体健康（p=0.08）和社会关系（p=0.26）领域外，这种关联在大多数生活质量测量中也很显著。
我们观察到，男性和女性医学生休闲时间PA量与生活质量之间存在很强的剂量效应关系。
