Model 1: adjusted for age, sex, and race. Model 2: Model 1 + income:poverty ratio, education, marital status, current smoking, BMI category, insurance, having a regular healthcare site, self-reported health, diagnosed diabetes, diagnosed hypertension, stage 3–5 chronic kidney disease, and hypertension duration. Abbreviations: BMI, body mass index; CI, confidence interval; DBP, diastolic blood pressure; HBPM, home blood pressure monitoring; SBP, systolic blood pressure.
