Background/Objectives: This study examined differences in physical activity (PA) and sedentary behavior among Korean cancer survivors compared to cancer-free individuals from 2017 to 2021 and identified differences based on their cancer treatment status.Methods: We used data for 28,528 adults (1585 cancer survivors and 26,943 cancer-free individuals) from the 2017–2021 Korea National Health and Nutrition Examination Survey. PA and sedentary behavior were assessed using the Korean version of the Global Physical Activity Questionnaire. We examined adherence to aerobic and resistance training guidelines, domain-specific activity, and sedentary time. We also analyzed the descriptive statistics and conducted chi-square tests, the Mann–Whitney U test, and the non-parametric Kruskal–Wallis test, stratified by demographic and clinical subgroups.Results: Compared with cancer-free individuals, cancer survivors showed significantly lower adherence to aerobic PA guidelines in 2017 (p< 0.01), 2018 (p< 0.05), and 2021 (p< 0.01). Transportation-related activity accounted for the highest share of the total PA (mean: 59.1%). Sedentary time increased among survivors from 8.1 h/day (2017) to 9.0 h/day (2021). In 2021, resistance training adherence was higher among survivors (24.7%) than among non-cancer individuals (22.9%). In the subgroup analyses, male sex, younger age, recent diagnosis, higher income, and living with a spouse were associated with higher adherence.Conclusions: The findings underscore a clear need to address both PA and sedentary behavior in cancer survivors, irrespective of treatment phase.
背景/目的：本研究旨在探讨2017年至2021年间韩国癌症幸存者与无癌人群在体力活动（PA）和久坐行为方面的差异，并根据癌症治疗状态分析其差异。方法：我们使用了2017-2021年韩国国家健康与营养调查中28,528名成年人（1585名癌症幸存者和26,943名无癌个体）的数据。采用韩文版全球体力活动问卷评估体力活动和久坐行为。我们考察了有氧运动和抗阻训练指南的依从性、特定领域活动量以及久坐时间。同时，我们分析了描述性统计数据，并进行了卡方检验、曼-惠特尼U检验和非参数克鲁斯卡尔-沃利斯检验，按人口学和临床亚组分层。结果：与无癌人群相比，癌症幸存者在2017年（p<0.01）、2018年（p<0.05）和2021年（p<0.01）对有氧运动指南的依从性显著较低。交通相关活动在总体力活动中占比最高（平均值：59.1%）。幸存者的久坐时间从8.1小时/天（2017年）增加至9.0小时/天（2021年）。2021年，幸存者的抗阻训练依从性（24.7%）高于无癌人群（22.9%）。亚组分析显示，男性、较年轻、近期确诊、较高收入以及与配偶同住等因素与较高的指南依从性相关。结论：研究结果强调，无论处于何种治疗阶段，癌症幸存者的体力活动和久坐行为均需得到充分关注。
