Objective: To analyze the possible dose-response association between components of sports participation (intensity, volume and previous engagement) and 4-year mortality rates among Brazilian adults.
Methods: 679 males and females (mean age among men = 66.7 ± 9.3 years old and mean age among women = 64.8 ± 8.9 years old) composed the study sample. Sports participation was assessed using Baecke’s questionnaire, which considers intensity, duration and previous engagement. Medical records were used to identify the cause of the death. Cox regression analysis was performed to determine the independent associations of exercise components and mortality.
Results: Participants that reported exercising at moderate-vigorous intensity (Moderate/vigorous: 4.1% versus None/light: 10.3% [p-value = 0.012]; HR = 0.42 [0.1 to 0.94)] and for more than four months (≥4 months: 5.3% versus <4 months: 10.2% [p-value = 0.038]; HR = 0.47 [0.24 to 0.94]) had lower mortality risk. The percentage of survival according to all-cause mortality was significantly higher for participants engaged in sports at moderate-vigorous intensity (p-value = 0.014), as well as for those engaged in sports for periods superior than four months (p-value = 0.036).
Conclusion: We found higher percentage of survival among adults engaged in sports at moderate-vigorous intensity and with at least four months of previous engagement. 相似文献
摘要：慢性疾病成为新世纪重要的致死风险因素，而身体活动不足成为引发慢性疾病的重要原因。2007年，由ACSM（American College of Sports Medicine）、AMA（American Medical Association）发起“运动是良医”的全球行动至今已有39个国家加入。主要采用文献资料法，梳理古典医学文化时期中“运动是良医”思想的源起。研究发现，早在公元前的古希腊、古代罗马、古代印度以及古代中国古典医学文化时期的医学典籍中就出现了“运动是良医”的思想和实践，Herodicus、Hippocrates、Galen、Susruta、华佗等对这一思想的发展做出了重要的贡献。虽然东西方医学与锻炼的结合具有同源异流、动静相宜等差异，但对于锻炼对疾病的预防和治疗的价值认识是一致的。甚至于早在古典医学文化时期就开始了身体锻炼与肥胖、糖尿病等疾病治疗的实践，并从自然、人体、锻炼、饮食等因素对疾病和健康有了整体的认识。文艺复兴后，由于医学技术的高速发展，“体”“医”开始分道扬镳，今天，体医结合重新受到医学和体育领域的重视，通过文献分析使我们对“运动是良医”这一古老的思想有更加深刻的认识。 相似文献
