Abstract
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 (p < 0.05). In the models stratified by sex, we observed significant associations between handgrip strength and cardiometabolic health in women (p < 0.001), but not in men. Thus, our findings suggest that replacing sedentary behavior with MVPA may contribute to improved cardiometabolic health.
Highlights
Cardiometabolic diseases are a public health problem worldwide [1]
In the isotemporal substitution (IS) models, replacing sedentary behavior (OR: 0.88, 95%confidence interval (CI): 0.80–0.97), light intensity activity (OR: 0.87, 95%CI: 0.79–0.96), and lifestyle activity (OR: 0.85, 95%CI: 0.75–0.97) with 30 min moderate-to-vigorous physical activity (MVPA) was significantly associated with a decreased risk of adverse cardiometabolic health (Table 3)
We found that time spent in MVPA was significantly associated with a reduced risk of adverse cardiometabolic health
Summary
Cardiometabolic diseases are a public health problem worldwide [1]. It represents a leading cause of disease burden and includes metabolic syndrome, ischemic heart disease, diabetes, and stroke [1]. The field of motor dynamics depicts daily activities during waking hours to be composed of sedentary behavior, light-intensity activity, and moderate-to-vigorous physical activity (MVPA) This is because there is a limited amount of time in a day at a person’s disposal, and individuals must reduce the time spent on one activity to devote some to others. Studies that examine the relationship between sitting behavior and the level of physical activity by applying the IS model to cardiometabolic disease are limited. If the results offer specific suggestions and a strategy to reduce sedentary behavior, a complex population approach that is practical and beneficial could be established This population-based cross-sectional study aimed to investigate the effect of behavioral transformations between sitting time and level of physical activity on cardiometabolic disease in Korean adults. We hypothesized that isotemporal substitution of sedentary behavior with any type of activity contributes to a decreased risk of cardiometabolic disease
