Constructing and testing a self-help intervention program for high blood pressure control in Korean American...

Area of Science:

• Cardiovascular Health
• Geriatric Medicine
• Health Disparities

Background:

• High blood pressure (HBP) remains a significant cardiovascular risk factor, particularly challenging for socially disadvantaged groups like Korean American immigrants.
• Ethnic minority and immigrant populations often face barriers to effective HBP management, leading to preventable complications.

Purpose of the Study:

• To evaluate the effectiveness of a culturally tailored, self-help intervention program for improving high blood pressure (HBP) control among first-generation Korean American seniors.
• To assess the impact of behavioral education, home blood pressure (BP) monitoring, and support groups on BP management in this underserved demographic.

Main Methods:

• A quasi-experimental study design was employed.
• The intervention included structured HBP management education, regular home BP monitoring, and monthly support group sessions facilitated by a bilingual nurse.
• Data were collected from 49 Korean American seniors (≥60 years) with HBP, with 31 completing a 6-month follow-up.

Main Results:

• The intervention significantly increased the proportion of participants achieving BP control (<140/90 mm Hg) from 29% at baseline to 69% at 6 months.
• Mean systolic blood pressure decreased from 142.7 mm Hg to 129.3 mm Hg.
• Mean diastolic blood pressure decreased from 87.1 mm Hg to 75.3 mm Hg.

Conclusions:

• The self-help intervention demonstrated clinical efficacy in improving HBP control rates within the Korean American senior population.
• This program offers a viable strategy for addressing HBP management in traditionally underserved immigrant communities.
• Culturally sensitive, community-based interventions are crucial for reducing cardiovascular health disparities.
