Abstract 13315: The Effect of a Community-based Health Literacy-enhanced Behavioral Intervention in Korean American Seniors With High Blood Pressure
Background: Great strides have been made in improving the nation’s heart health during the last two decades, health disparities still exist within many ethnic minority populations. These individuals often suffer from insufficient health literacy, which severely limits their ability to make appropriate health decisions. In particular, as a member of first generation immigrant groups, Korean American seniors (KAS) with chronic disease such as hypertension encounter very stiff language and cultural barriers to accessing the complicated U.S health care system and have only limited personal resources.
Purposes/ methods: To address this unmet health need of this underserved group, we designed a community-based clinical trial to test the efficacy of a comprehensive HBP management program that focused on health literacy among Korean American senior (KAS). The health literacy self-help intervention program for HBP (HL-SHIP-HBP) was a community-based, prospective controlled trial targeting KAS with hypertension in the Baltimore-Washington metropolitan area. Using an adaptive stratified randomization method, we selected a total of 22 ethnic Korean churches and senior centers in the region for use as study sites on the basis of their size and location, then randomly assigned each of them as either an intervention group site or control group site. Eligible members from each site were then screened and enrolled in the study. Eligibility criteria: Participants were Korean Americans 60 years of age or older, with systolic BP (SBP) > 140 mm Hg and/or diastolic BP (DBP) > 90 mm Hg on two separate measurements or on antihypertensive medication.
Results: A total of 369 KAS (mean age, 70.9 ± 5.3 years) completed the program: 184 in the intervention and 185 in the control group. Main outcomes were measured at baseline, 6, 12, and 18 months. The findings indicate that the program (HL-SHIP-HBP) was effective in controlling BP in this ethnic/linguistic minority population. The BP control rates of the intervention and control groups were 49.5% vs. 43.2% at baseline, 58.5% vs. 42.4% at 6 months, 67.9 vs. 52.5 at 12 months, and 54.3% vs. 53.0% at 18 months.
The potential contribution of health literacy to the long-term sustainability of HBP control will be discussed.
