Demographic factors included age (continuous), sex, and education level.
bLifestyle factors included any physical activity participation, alcohol consumption (within the past year—yes/no), cigarette smoking (never, former, or current), and use of energy drinks (yes/no).
cContinuous blood pressure variables.
dSelf-rated health (SRH) was evaluated by asking, “how would you say your health compares to others your age.” Poor SRH = worse than others my age. Good SRH = better or same as others my age.
