Reducing sedentary behavior and increasing physical activity may be important for maintaining good cardiometabolic health. However, many studies have focused on the independent effect of sedentary behavior and physical activity, but it is unclear whether replacing time spent in sedentary behavior with physical activity is beneficial for cardiometabolic health. Therefore, this population-based cross-sectional study aimed to investigate the effect of behavioral transformations between sedentary behavior and level of physical activity on cardiometabolic health in Korean adults using data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2014-2017. The study participants included 2197 adults from the KNHANES. In the partition model, moderate-to-vigorous physical activity (MVPA) was significantly associated with adverse cardiometabolic health, adjusted for potential confounding factors. The odds ratio for adverse cardiometabolic health significantly decreased with the replacement of sedentary behavior and light intensity activity with MVPA in the isotemporal substitution model ( < 0.05). In the models stratified by sex, we observed significant associations between handgrip strength and cardiometabolic health in women ( < 0.001), but not in men. Thus, our findings suggest that replacing sedentary behavior with MVPA may contribute to improved cardiometabolic health.
减少久坐行为和增加身体活动可能对维持良好的心血管代谢健康很重要。然而，许多研究都集中在久坐行为和身体活动的独立影响上，但尚不清楚用身体活动替代久坐时间是否有益于心血管代谢健康。因此，本项基于人群的横断面研究使用 2014-2017 年韩国国家健康和营养调查（KNHANES）的数据，旨在探讨韩国成年人中久坐行为和身体活动水平之间的行为转换对心血管代谢健康的影响。研究参与者包括来自 KNHANES 的 2197 名成年人。在分区模型中，经过潜在混杂因素调整后，中等到剧烈的身体活动（MVPA）与不良的心血管代谢健康显著相关。在等时替代模型中，随着 MVPA 替代久坐行为和低强度活动，不良心血管代谢健康的比值比显著降低（<0.05）。在按性别分层的模型中，我们观察到手握力与女性心血管代谢健康之间存在显著关联（<0.001），但在男性中则没有。因此，我们的研究结果表明，用 MVPA 替代久坐行为可能有助于改善心血管代谢健康。
