*All models were adjusted for enrollment age, sex, ethnicity, race, current smoking status, and enrollment site. The rationale for cut-offs for the above outcomes is as follows: a CAC score >0 suggests some coronary plaque; an hsCRP level of 3 or higher suggests a high risk for cardiovascular events; a mean PHQ-9 score of 5 or higher suggests depression; a mean GAD-7 score of 10 or higher suggests general anxiety disorder; and a mean step count of 4000 is the average step count for Americans. CAC, coronary artery calcium; CI, confidence interval; GAD-7, General Anxiety Disorder-7; hsCRP, high-sensitivity C-reactive protein; OR, odds ratio; PHQ-9, Patient Health Questionnaire-9.
