GAD, generalized anxiety disorder; MDD, major depressive disorder; PD, panic disorder; EF, executive function; EM, episodic memory; HTN, hypertension; DM, diabetes mellitus; BMI, body mass index; SOC, sense of control; GC, global cognition; Min, minimum; Max, maximum
Note: Gender was coded as 1 = male and 2 = female. EF and EM reflect composite z-scores. Education level ranged from 1 = no school/ some grade school to 12 = medical, law, or doctoral degree. HTN and DM medication use were coded as 1 = yes and 2 = no. Exercise status was coded as 1 = yes and 2 = no. Sense of control was coded from 1 = strongly disagree to 7 = strongly agree.
