Abbreviations: MVPA=moderate-to-vigorous physical activity; %MVPA=percent of wear time in moderate-to-vigorous physical activity per day; WC=Waist circumference; SBP=systolic blood pressure; DBP=diastolic blood pressure; HDL-C=high-density lipoprotein cholesterol; LDL-C=low-density lipoprotein cholesterol.

Adjusted for age, sex, race/ethnicity, and poverty-to-income ratio.

Model 1 are associations between the continuous measure of %MVPA and the cvd risk factors. Beta estimate and 95% CI of linear term is shown.

Model 2 are associations between %MVPA latent classes and the cvd risk factors. Class 2, 3 and 4 are compared to Class 1 (least active class).

⁴

Model 1 also includes the quadratic term for %MVPA.

Note: Bolded associations have a p-value <0.05
