Association between time spent in each intensity category (SB, LLPA, HLPA and MVPA) and BMI, blood glucose, and HDL cholesterol for OPACH Study (N=4,655). Each model was adjusted for average awake wear time (minutes), age, BMI (except when BMI was the outcome), race/ethnicity, and education. Separate linear regression analyses were conducted based on PA metrics derived from AAI and count cutpoints.
