Abstract
OBJECTIVE 1) Evaluate the efficacy of e-Counseling vs. Control to promote lifestyle behaviors at 4 and 12-month follow-ups, 2) examine whether these behaviors changes were associated with lower blood pressure (BP), and Framingham Risk Index (FRI) at 12-month. METHODS Hypertensive patients (n = 264) were randomized to the e-Counseling or the Control group. Primary trial outcome was BP and secondary outcomes included exercise and diet behaviors. This study presented the results of secondary outcomes. Linear mixed models evaluated treatment effects at 4 and 12-month. Treatment-by-sex exploratory analyses were conducted if no main treatment effect was observed. RESULTS Daily steps significantly improved in e-Counseling vs. Controls at 12-month. Urinary sodium at 12-month did not significantly differ between the groups, but treatment-by-sex analysis showed that e-Counseling females lowered urinary sodium relative to Controls at 12 months. Improvements in steps and dietary sodium were significantly associated with improvements in BP and FRI at 12-month. CONCLUSION This hypertension e-Counseling protocol can promote long-term lifestyle behavior changes. Adherence to the lifestyle behavior change was associated with BP and FRI reduction at 12-month. PRACTICE IMPLICATIONS The hypertension e-counseling protocol has the potential to improve hypertension care and intervention reach.

Abstract
BACKGROUND The efficacy of internet-based interventions to improve hypertension management is not established. We evaluated the therapeutic benefit of e-counseling by adapting best evidence guidelines for behavioral counseling. METHODS AND RESULTS This multicenter double-blind randomized controlled trial included assessments at baseline, 4 months, and 12 months. Participants were 35 to 74 years of age and diagnosed with hypertension: systolic/diastolic blood pressure (BP) 130 to 180/85 to 110 mm Hg. BP was assessed by automated office measurement. E-Counseling used multimedia and interactive tools to increase motivation and skill for self-care (exercise, diet, medication adherence, and smoking cessation). Control used self-care education. Frequency of contact by our e-platform was equal for both trial arms. Primary end points were change at 4 and 12 months in systolic BP, diastolic BP, pulse pressure, total lipoprotein cholesterol, low-density lipoprotein cholesterol, total lipoprotein cholesterol/high-density lipoprotein cholesterol ratio, non-high-density lipoprotein cholesterol, and Framingham 10-year cardiovascular risk index. Intention-to-treat analysis used generalized linear models adjusted for baseline measures, sex, and medications. Among 264 participants, mean age was 57.6 years (SE, 0.6), 58% were women, with 83% on antihypertensive medications. At 12 months, e-counseling versus control evoked greater reduction in systolic BP (-10.1 mm Hg [95% confidence interval (CI), -12.5, -7.6] versus -6.0 mm Hg [95% CI, -8.5, -3.5]; P=0.02); pulse pressure (-5.2 mm Hg [95% CI, -6.9, -3.5] versus -2.7 mm Hg [95% CI, -4.5, -0.9]; P=0.04), and Framingham risk index (-1.9% [95% CI, -3.3, -0.5] versus -0.02% [95% CI, -1.2, 1.7]; P=0.02), respectively. Among males in e-counseling versus control, 12-month end points included lower diastolic BP (P=0.01), non-high-density lipoprotein cholesterol (P=0.04), total lipoprotein cholesterol (P=0.03), and a trend for total lipoprotein cholesterol/high-density lipoprotein cholesterol ratio (P=0.07). CONCLUSIONS To our knowledge, this is the first double-blind randomized trial of e-counseling for hypertension. Added benefit for medical therapy was achieved by combining available technology with a clinically organized protocol of motivational and cognitive-behavioral counseling.
