Overview
Brief Summary
The largest epidemiologic study of Hispanic/Latino participants thus far, i.e., the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) documented that 80% of men and 71% of women have at least one major cardiovascular disease (CVD) risk factor. The American Heart Association emphasizes that current CVD prevention efforts are sparse and ineffectual in minority populations and acknowledges the need for new and more effective disease prevention strategies. This proof-of-concept study and pilot randomized clinical trial seeks to implement and evaluate a novel internet-based 5-week Positive Psychology (PP) Intervention (compared to an attention control condition) in Hispanic/Latino adults with uncontrolled hypertension, i.e., elevated 24-hour ambulatory blood pressure, with primary interest in testing efficacy for clinically meaningful improvements in cardiovascular function.
Detailed Description
The study features piloting of a randomized trial to determine whether an internet-based positive psychology (PP) intervention is associated with greater improvements in blood pressure compared to an attention control condition. The pilot trial additionally evaluates the efficacy of the internet-based PP intervention with respect to psychological well-being, hypertension-related health behaviors, autonomic cardiac control, and high-sensitivity C-reactive protein. Serum blood assays will facilitate exploration of mechanistic indicators linking psychological well-being to cardiac functioning.

Outcomes
Primary Outcomes
Change from Baseline Ambulatory Blood Pressure at 5- and 12-weeks
Time Frame: Baseline, 5-, and 12-weeks
The ambulatory blood pressure monitor (the Spacelabs Healthcare 90217A ABPM) will capture 24-hour daytime and nighttime systolic and diastolic blood pressure reading in the natural environment and will capture heart rate variability. The ambulatory blood pressure monitor will record the subject's systolic and diastolic blood pressure periodically every 30 minutes to one hour and the data will be stored in the internal memory until uploaded to a companion application for visualization and analysis. In addition to ambulatory blood pressure the wearable device will record pulse waves on a beat to beat basis from which heart rate variability will be calculated and analyzed.
