Prevalence and odds ratios of low antihypertensive medication adherence associated with depressive symptoms among participants taking and not taking antidepressant medication

	No use of antidepressant medication			Use of antidepressant medication^a
	No depressive symptoms (n=1,730)	Depressive symptoms present (n=218)	p value	No depressive symptoms (n=165)	Depressive symptoms present (n=66)	p value
Mean (SD) adherence score	7.28 (1.03)	6.87 (1.33)	<0.01	7.24 (0.97)	6.80 (1.30)	0.02

Mean adherence score was assessed with the Morisky Medication Adherence Scale-8 item

Depressive symptoms were defined as a score ≥16 on the Center for Epidemiologic Studies-Depression Scale

Using antidepressant medication—Participant filled at least one antidepressant medication within 60 days prior to the survey

Low antihypertensive medication adherence—Morisky Medication Adherence Scale score <6

Adjusted for age, gender, race, education, marital status and Charlson comorbidity score

OR Odds ratio, CI Confidence interval, SD Standard Deviation
