Physical activity, sufficient sleep, and limiting sedentary time may improve cancer survivorship.
Utilizing US nationally representative samples from the National Health Interview Survey 1997-2018 and the National Health and Nutrition Examination Survey 2007-2018, this study investigated the trends of meeting physical activity guidelines, insufficient sleep duration, and sitting time in US cancer survivors (n = 58 527) and noncancer adults (n = 640 109).
From 1997 to 2018, the prevalence of meeting physical activity guidelines was consistently lower in cancer survivors than in noncancer adults. Among cancer survivors, the prevalence of meeting physical activity guidelines increased from 34.9% (95% confidence interval [CI] = 33.1% to 36.8%) to 46.5% (95% CI = 45.0% to 48.1%) for aerobic (≥150 minutes per week at moderate intensity or 75 minutes per week at vigorous intensity), from 13.9% (95% CI = 12.8% to 15.1%) to 23.1% (95% CI = 21.8% to 24.4%) for muscle strengthening (≥2 days per week) activities, and from 9.5% (95% CI = 8.4% to 10.7%) to 17.9% (95% CI = 16.7% to 19.1%) for both combined (all Ptrend < .001). From 2004 to 2018, the prevalence of insufficient sleep duration (<7 hours per day) increased from 28.4% (95% CI = 26.3% to 30.5%) to 30.8% (95% CI = 29.3% to 32.2%) (Ptrend = .004). Daily sitting time increased from 6.09 hours per day (95% CI = 5.71 to 6.46 hours per day) in 2007-2008 to 7.36 hours per day (95% CI = 7.05 to 7.68 hours per day) in 2013-2014 and attenuated to 6.20 hours per day (95% CI = 5.74 to 6.65 hours per day) in 2017-2018. The pattern of physical activity, sleep, and sitting time varied by sex, race and ethnicity, body mass index, cancer type, and time since cancer diagnosis.
More than half of US cancer survivors did not meet physical activity guidelines, and a large proportion had insufficient sleep duration and prolonged sitting time.
身体活动、充足的睡眠和限制久坐时间可能会改善癌症患者的生存状况。
本研究利用了美国国家健康访谈调查 1997-2018 年和国家健康与营养检查调查 2007-2018 年的全国代表性样本，调查了美国癌症幸存者（n=58527）和非癌症成年人（n=640109）中符合身体活动指南、睡眠不足和久坐时间的趋势。
1997 年至 2018 年，癌症幸存者符合身体活动指南的比例始终低于非癌症成年人。在癌症幸存者中，符合身体活动指南的比例从 34.9%（95%置信区间[CI]：33.1%至 36.8%）增加到 46.5%（95%CI：45.0%至 48.1%），用于有氧运动（每周至少 150 分钟中等强度或每周 75 分钟剧烈强度），从 13.9%（95%CI：12.8%至 15.1%）增加到 23.1%（95%CI：21.8%至 24.4%）用于肌肉强化（每周至少 2 天）活动，从 9.5%（95%CI：8.4%至 10.7%）增加到 17.9%（95%CI：16.7%至 19.1%）用于两者结合（所有 Ptrend<.001）。从 2004 年到 2018 年，睡眠不足（每天<7 小时）的比例从 28.4%（95%CI：26.3%至 30.5%）增加到 30.8%（95%CI：29.3%至 32.2%）（Ptrend=0.004）。每天的久坐时间从 2007-2008 年的 6.09 小时（95%CI：5.71 至 6.46 小时/天）增加到 2013-2014 年的 7.36 小时（95%CI：7.05 至 7.68 小时/天），并在 2017-2018 年减少到 6.20 小时（95%CI：5.74 至 6.65 小时/天）。活动、睡眠和久坐时间的模式因性别、种族和民族、体重指数、癌症类型和癌症诊断后时间而异。
超过一半的美国癌症幸存者不符合身体活动指南，相当大比例的人睡眠不足且久坐时间过长。
