Physical activity and life quality of university professors

Abstract Background The quality of life is a subject that has been investigated in several areas of knowledge and under many approaches. Objective To investigate the practice of leisure time physical activity among university professors and to analyze its association with quality of life. Method The target population was professors of the Federal University of the Rio Grande, Brazil, who were active and worked on campus in the city of the Rio Grande in the second half of 2015. The collection was carried out by completing an electronic questionnaire. The quality of life was assessed by the instrument The Medical Outcomes Study 36- item Short Form Health Survey (SF-36). Data were analyzed by analysis of variance test or nonparametric Kruskal-Wallis test. Results The sample included 270 participants, representing 40% of eligible professors. There were 70.4% that reported performing some physical activity in leisure time, and 43.0% (95%CI 37.0 to 48.9) were considered physically active (≥150 min/week). This group obtained the highest score for quality of life, suggesting a linear positive association between physical activity and the score of quality of life (p摘要 背景：生活质量是多学科领域中经多种研究范式开展探讨的研究主题。目的：探究巴西大学教师的闲暇体育锻炼实践情况，并分析其与生活质量的关联性。方法：本研究的目标人群为2015年下半年，于巴西南里奥格兰德联邦大学里奥格兰德市校本部在职在岗的教师。数据采集通过电子问卷形式完成；生活质量评估采用医学结局研究36条目简明健康量表（Medical Outcomes Study 36-item Short Form Health Survey，SF-36）。数据分析采用方差分析或非参数Kruskal-Wallis检验。结果：本次研究共纳入270名研究对象，占符合纳入标准教师总数的40%。其中70.4%的受访者报告在闲暇时间开展了体育锻炼，43.0%（95%置信区间：37.0至48.9）被归类为体育活动活跃人群（每周锻炼时长≥150分钟）。该人群的生活质量评分最高，提示闲暇体育锻炼与生活质量评分存在线性正相关关系（p
