HYPERTENSION
Intervention participants received up to 12 coaching calls (20 min/call), scheduled every 2 weeks for the first 6 months. Coaches were trained on self-determination theory and motivational interviewing. A random sampling of coaches’ calls was assessed with a fidelity checklist, and coaches were given feedback monthly with a behavioral scientist.Intervention participants received an upper arm BP monitor (Omron, 7 Series) and were instructed to take 2 BP measurements separated by 1 minute, 3 days per week that were shared with the health coach during calls. Detailed instructions on conducting home BP monitoring were provided.Control participants received a handout providing an overview on the diagnosis of hypertension at enrollment, and it was recommended to continue receiving usual clinical careAll study participants returned for 6-month (visit 3 and 4) and 12-month (visit 5 and 6) follow-up. These visits included in-office BP measurement; height, weight, and waist circumference measurement; participant-level data collection; and completion of surveys referenced previously. At the end of each visit, participants were fitted with the AMBP monitor to return the following day for interpretation.
