* SB: sedentary behavior; MVPA: moderate to vigorous physical activity
** ISM was adjusted for sex, age, marital status, year, sleep, and occupational physical activity and total behavior time. Single model was adjusted for sex, age, marital status, and year. Partition model was adjusted for sex, age, marital status, year, and other types of physical activity
(a) SB was replaced by physical activities
(b) Walking was replaced by SB and MVPA
(c) MVPA was replaced by SB and walking
*** This calculation involved multiplying the frequency (days), hours (per day), and minutes (per day), which were then divided by 7 days and converted into 5 min units
