Abstract 186: Longer Term Effect of Lifestyle Intervention on Blood Pressure Control Among African Americans: One Year Follow-up of Shake, Rattle & Roll Trial

Background: In Kaiser Permanente Northern California (KPNC), an integrated healthcare system with a high overall hypertension (HTN) control rate, blacks still had poorer blood pressure (BP) control than whites. The “Shake, Rattle and Roll” (SRR) trial is named for: 1) “shake” the salt habit; 2) “rattle” the intensity of current BP management; and 3) adapt and “roll” out the interventions to other communities. Successful lifestyle (LS) interventions tend to be short-lived. We evaluated the effect of LS intervention in SRR on BP control at 12 months after the trial ended. Methods: SRR is a pragmatic cluster-randomized controlled trial conducted at Kaiser Oakland. All PCPs and their panels of black patients were randomized, stratified by panel size, to one of 3 arms: 1) usual care (UC); or 2) enhanced monitoring (EM) of KPNC BP management protocol; or 3) culturally tailored LS coaching focused on the DASH eating plan. Black patients from KPNC HTN Registry with a persistent high BP reading ≥ 140/90 qualified ...
