Health Literacy-Focused Program to Improve Blood Pressure Control in Korean Americans
Summary
Many Korean Americans are at risk for developing high blood pressure. Low health literacy levels may play a role in this risk. The purpose of this study is to evaluate a literacy-focused program aimed at reducing blood pressure levels in older Korean Americans.
Description
In the last decade, significant progress has been made in improving the heart health of individuals in the United States. However, despite these advances, many racial and ethnic minority groups still have high rates of cardiovascular disease. Korean Americans, in particular, are more prone to developing high blood pressure than other Americans or individuals living in Korea. Possible reasons for this may include stress, diet, or lifestyle changes that occur as a result of immigration. Because many Korean Americans have low health literacy skills, it may be harder for them to understand medication dosing instructions, keep track of medical appointments, or comprehend written medical information. Korean Americans have traditionally been identified as a "hard to reach" group, and few programs have specifically targeted these individuals with regards to improving blood pressure control. The purpose of this study is to evaluate a health literacy-focused intervention that aims to improve blood pressure control among older Korean Americans. The results from this study may be helpful in developing future literacy-focused blood pressure programs targeted to minority groups in the United States.
In this study, participants will be randomly assigned to either a literacy-focused high blood pressure intervention or a wait-list control group, which will initially involve usual care from a regular medical provider. Participants in the intervention group will attend a weekly 2-hour educational session for 6 weeks. Bilingual research nurses and other professionals will facilitate these sessions, and each participant will receive a Korean language workbook with examples of medical terminology, prescription and appointment slips, and blood pressure management strategies. For 12 months, participants will self-monitor their blood pressure and record these measurements through a telephone management system. Community health workers will conduct telephone counseling on a monthly basis and those participants with uncontrolled blood pressure will receive more intensive support and follow-up counseling. Study visits will occur at Week 6 and Months 6, 12, 18, and 24, at which time blood pressure, height, and weight will be measured. In addition, participants will complete questionnaires that assess health literacy, high blood pressure knowledge, problem solving and communication skills, treatment adherence, health care utilization, and quality of life. Participants in the control group will take part in the intervention once the study has been completed.

Medical and Biotech [MESH] Definitions
Hypertension
Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.
Blood Pressure Monitoring, Ambulatory
Method in which repeated blood pressure readings are made while the patient undergoes normal daily activities. It allows quantitative analysis of the high blood pressure load over time, can help distinguish between types of HYPERTENSION, and can assess the effectiveness of antihypertensive therapy.
High-intensity Focused Ultrasound Ablation
The use of focused, high-frequency sound waves to destroy tissue. It is sometimes used in conjunction with but is distinct from INTERVENTIONAL ULTRASONOGRAPHY.
Hypertension, Malignant
A condition of markedly elevated BLOOD PRESSURE with DIASTOLIC PRESSURE usually greater than 120 mm Hg. Malignant hypertension is characterized by widespread vascular damage, PAPILLEDEMA, retinopathy, HYPERTENSIVE ENCEPHALOPATHY, and renal dysfunction.
Hypertension, Pregnancy-induced
A condition in pregnant women with elevated systolic (>140 mm Hg) and diastolic (>90 mm Hg) blood pressure on at least two occasions 6 h apart. HYPERTENSION complicates 8-10% of all pregnancies, generally after 20 weeks of gestation. Gestational hypertension can be divided into several broad categories according to the complexity and associated symptoms, such as EDEMA; PROTEINURIA; SEIZURES; abnormalities in BLOOD COAGULATION and liver functions.
