Associations between Minutes spent in Sedentary Behavior and at Very Light, Light, and Moderate Intensity Physical Activity (PA), and Cardiovascular Risk Factors, Disability and Disease Activity from the Regression Analysis. Values represent standardized coefficients (β), R² change (R²Δ), and p values from adjusted linear regression models of each category of physical activity on each variable. Models are adjusted for age, gender, and cohort.
