Trial Outcomes & Findings for Interactive Web Program and Health Coaching for Prehypertensive Adults (NCT NCT02637063)

NCT ID: NCT02637063

Last Updated: 2017-03-15

Results Overview

Blood pressure measurements were taken by participants using a validated, WIFI-enabled blood pressure cuff manufactured by BlipCare and provided to study subjects prior to the baseline assessment. Measurements were automatically uploaded over a WIFI connection to the BlipHub app and study outcomes database. Participants followed a standardized measurement protocol based on the American Heart Association protocol for home blood pressure measurement, involving three consecutive measurements, taken one minute apart after a five-minute seated resting period. Measurements were not observed.

PRIMARY outcome

Timeframe: Baseline, 12 weeks, 24 weeks

Body weight measurements were taken by participants using a validated, WIFI-enabled weight scale manufactured by BlipCare and provided to study subjects prior to the baseline assessment. Measurements were automatically uploaded over a WIFI connection to the BlipHub app and study outcomes database. Participants were instructed to take weight measurements at the same time of day each time, preferably first thing in the morning after using the bathroom and before eating or drinking. The weight measurement taken on the date and time closest to the completion date and time of each individual's online survey for that assessment point was analyzed. If no measurements were available within two weeks on either side of that date, weight measurements were considered missing for that assessment period.

PRIMARY outcome

Timeframe: Baseline, 12 weeks, 24 weeks

Participants were asked about their diet during the past month, using DASH-diet related items adapted from several validated food frequency questionnaires. Participants reported on servings consumed (e.g., never, 1-3 times last month, up to 5 or more times a day) of the following foods: fruits, vegetables, dairy, fats and meat. Number of servings was computed for heart-healthy foods (fruits, vegetables and lean meats).

SECONDARY outcome

Timeframe: Baseline, 12 weeks, 24 weeks

Participants were asked to self-report on days in the past two weeks in which they engaged in specific behaviors to prepare for or support healthy eating and physical activity (i.e., "preparation behaviors"). The scale comprised 15 items (e.g., thought about what you might do to try to lose weight) assessed on a 5-point scale (1=none (min), 5=12-14 days (max)). Mean score is reported, with higher scores indicating more frequent preparation behaviors. The scale showed good reliability (alpha=.91).

Five items assessed participants' confidence to engage in JNC-recommended healthy behaviors using a 5-item response option (1=not at all confident (min), 5=very confident (max)). Mean score is reported, with higher scores indicating higher self-efficacy. The scale showed good reliability (alpha=.79).
