简要总结

Hypertension (HTN) has a greater impact on African Americans (AA) than any other U.S. racial group. Uncontrolled blood pressure (BP) contributes to higher rates of disability, death, and health resource use among AA. HTN is the single most influential risk factor for cardiovascular disease (CVD), as well as a risk factor for the incidence of stroke, diabetes, chronic kidney disease, and dementia. Importantly, older adults account for 15% of the U.S. population, and two-thirds of older adults over age 60 have HTN, with higher rates observed in AA older adults. Strategies to support self-managing HTN and BP control are crucial as the older population is projected to age considerably and become more racially and ethnically diverse. Research has documented the negative effects on health and health outcomes of poorly controlled BP and is one of the most important modifiable CVD risk factors. Lower BP targets will require aggressive management and an increase in antihypertensive medications. Therefore, to achieve lower targets in this population, greater efforts, including patient-centered methods will be needed to support self-managing HTN, especially in terms of medication adherence.

As we shifted into the digital age, the use of mHealth technologies (smart phones, applications, SMS or text messaging) has been a powerful approach and mechanism for the treatment and management of chronic diseases. However, behavioral interventions that incorporate technology do not reach minorities or disadvantaged AA older adults with HTN. OPtimizing Technology to Improve Medication Adherence and BP Control (OPTIMA-BP) will leverage existing knowledge of effective technology-based components for HTN self-management to support and improve BP control using unique aspects of mHealth platforms in AA older adults. Findings from this study, if confirmed, will improve BP control and support self-managing HTN, as well as has the potential to close the health disparity gap between AA and non-AA older adults with HTN.

详细描述

OPTIMA-BP investigates the effectiveness of a technology-based intervention (TBI) for hypertension self-management and to improve blood pressure (BP) control.

The investigators aims to:

  1. To test the effects of OPTIMA-BP over a 12-month period vs. a 6 month waitlist control (WL) on systolic BP and health-related quality of life (HRQOL) in African American older adults with HTN in a prospective, randomized control trial.
  2. To test if the attitudinal/knowledge mechanisms of self-management (HTN knowledge, self-efficacy, perceived social support) and proximal behavioral target mechanisms (taking medications to reduce systolic BP, diet, exercise) mediate OPTIMA-BP vs. WL's impact on the primary and secondary outcomes (systolic BP, diastolic BP, HRQOL, serum lipids, and at least 62% of the sample with BP <130/80 mmHg) over a 12-month period.

The investigator also aims to:

3. Utilize qualitative evaluation to confirm self-management barriers and perceived strengths or limitations of the intervention, which will inform future refinements should these randomized controlled trial (RCT) findings be positive

结局指标

主要结局

Health Related Quality of Life (HRQOL)

时间窗: Baseline - 6 months

Assess HRQOL using PROMIS Global Health-10. (Raw score range from 4-20, higher score represents better health

Blood Pressure Control

时间窗: Baseline - 6 months

Systolic BP \< 130 mmHg or Diastolic BP \< 80 mmHg, represents improved blood pressure control, measured digitally using a standard automatic BP device (Omron HEM-907 XL).

次要结局

  • Controlled BP (<130/80 mmHg)(Baseline - 6 months)
  • Biological risk markers(Baseline - 6 months)
