Beta (β) represents increase in blood pressure (mmHg) for each additional hour of ST per day.
a Median MVPA minutes per week was 262.9 minutes.
b Model 1 adjusts for age, race, education level, current smoking, and anti-hypertensive medication.
c Model 3 adjusts for Model 1 + log-transformed MVPA and BMI.
