To examine the independent associations of leisure-time aerobic physical activity (PA) and resistance exercise (RE) on all-cause mortality in cancer survivors.
Patients included 2863 male and female cancer survivors, aged 18 to 81 years, who received a preventive medical examination between April 8, 1987, and December 27, 2002, while enrolled in the Aerobics Center Longitudinal Study in Dallas, Texas. Physical activity and RE were assessed by self-report at the baseline medical examination. Cox proportional hazards regression analysis was performed to determine the independent associations of PA and RE with all-cause mortality in participants who had a history of cancer.
Physical activity in cancer survivors was not associated with a lower risk of all-cause mortality. In contrast, RE was associated with a 33% lower risk of all-cause mortality (95% CI, 0.45-0.99) after adjusting for potential confounders, including PA.
Individuals who participated in RE during cancer survival had a lower risk for all-cause mortality. The present findings provide preliminary evidence for benefits of RE during cancer survival. Future randomized controlled trials examining RE and its effect on lean body mass, muscular strength, and all-cause mortality in cancer survivors are warranted.
研究休闲时间有氧运动 (PA) 和抗阻运动 (RE) 对癌症幸存者全因死亡率的独立相关性。
患者包括 2863 名年龄在 18 至 81 岁之间的男性和女性癌症幸存者,他们于 1987 年 4 月 8 日至 2002 年 12 月 27 日在德克萨斯州达拉斯的有氧运动中心纵向研究中接受了预防性体检。在基线体检时通过自我报告评估身体活动和 RE。采用 Cox 比例风险回归分析确定在有癌症病史的参与者中,PA 和 RE 与全因死亡率的独立相关性。
癌症幸存者的身体活动与全因死亡率降低无关。相比之下,在调整了潜在混杂因素(包括 PA)后,RE 与全因死亡率降低 33%相关(95%CI,0.45-0.99)。
在癌症存活期间进行 RE 的个体全因死亡率较低。目前的研究结果为癌症存活期间进行 RE 的益处提供了初步证据。未来需要进行随机对照试验,以研究 RE 及其对癌症幸存者瘦体重、肌肉力量和全因死亡率的影响。
