Self-Management and Resilience Trajectories in African American Adults With Hypertension

Overview

Hypertension (HTN) rates have increased worldwide, but the most significant increase in the incidence of morbidity and mortality has been in African Americans (AA)1,2 (43% vs 27% for other U.S. population groups). Despite evidence of positive benefits from lifestyle modification (healthy diet, reduced sodium intake, increased physical activity, smoking cessation) and prescribed antihypertensive therapy (AHT) many AA with HTN do not adhere to their treatment regimens. Consistent, effective lifelong self-management is required to sustain optimal BP control and thus reduce morbidity and mortality. Self-managing HTN to a blood pressure (BP) \<130/80 mm Hg presents challenges such as juggling multiple medications and health care providers, dealing with complex recommendations and treatment regimens, and coping with negative emotional states. Few studies have examined the biopsychosocial mechanisms that foster effective HTN self-management and resilience among AA living with HTN. Understanding the mechanisms that influence HTN self-management and resilience in AA holds the promise of new modifiable targets for behavior-change interventions. This study explores the relationship among resilience precursors on hypertension (HTN) self-management behaviors, stress response, and the effects that these relationships have on health outcomes-health-related quality of life (HRQOL) and blood pressure (BP) in African Americans (AA) with HTN over a 6-month period.

This study identifies profiles of self-management and the resilience trajectories in AA with HTN can lead to culturally appropriate, patient-centered interventions that improve their HTN self-management, quality of life, and long-term compliance. This study aims to: 1. Assess the association among resilience precursors (dispositional optimism and resilience, emotion regulation); stress response (physiological: cortisol, interleukins \[IL-6\] and psychological: depression cognitions, perceived stress); hypertension self management behaviors (self-efficacy for chronic disease management, medication adherence to antihypertensives); and health outcomes (HQROL and BP) in AA with HTN at baseline and months 3 and 6. 2. Determine if stress response mediates the relationship between resilience precursors and health outcomes over time when controlling for risk regulators. 3. Determine if self-management behaviors mediates the relationship between resilience precursors and health outcomes over time when controlling for risk regulators. 4. Identify resilience trajectory patterns and factors that influence HTN self-management behaviors over time.
