MVPA, moderate‐vigorous physical activity; SB, sedentary bout; ST, sedentary time.
Estimates of the regression coefficient are provided, with SEs.
All models are adjusted for age, ethnicity, education, annual household income, marital status, smoking status, alcohol consumption, body mass index, total ST, and accelerometer wear time. Models are also adjusted for variables within the specific models presented.
Model 1: All physical activity and SB/break variables.
Model 2: Sex comparison of estimates with all physical activity and SB/break variables.
Model 3: Sex comparison of estimates with bouted physical activity and all SB/break variables.
Bold indicates P‐values < 0.05.
Indicates statistically significant CVD interaction (P < 0.05).
