Covariables were age, sex, race/ethnicity, education, body mass index, diabetes, smoking history, antihypertensive medication use, social support, and social isolation.

Abbreviations: DBP, diastolic blood pressure; SBP, systolic blood pressure.

^a P value for the overall test.

*P < 0.05 and **P ≤ 0.01 for the comparison vs. reference group.
