*Model 1: unadjusted; Model 2, adjusted for demographic characteristics (age, race, education, marital status, poverty-income ratio) and lifestyle-related behaviors (current smoking, excessive drinking, and physical activity); Model 3: further adjusted for the number of chronic conditions (including diabetes, hypertension, congestive heart failure, coronary artery disease, stroke, arthritis, asthma, chronic bronchitis, emphysema, liver disease, thyroid disease, renal diseases, sleep disorders, cancer, and disability); Model 4: further adjusted for current depression; Model 5: further adjusted for both the number of chronic conditions and current depression.
