Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

1

Literacy-focused high blood pressure intervention. The intervention group will receive the health literacy -focused hypertension management intervention that will be delivered through 6 weeks of highly interactive group sessions in a classroom setting, followed by telephone counseling once a month for 12 months. Also, the intervention group will concurrently use home blood pressure monitoring with telephone transmission for 12 months.

Group Type EXPERIMENTAL

Health Literacy-Focused High Blood Pressure Intervention

Intervention Type BEHAVIORAL

Participants assigned to the intervention group will attend a weekly 2-hour educational session for 6 weeks that will cover topics such as learning medical terminology, understanding the content of prescription and appointment slips, and blood pressure (BP) management strategies. Upon completion of the educational sessions, participants will submit BP measurements via telephone monitoring system for 12 months and Community Health Worker (CHW) will conduct telephone counseling once every month during the same 12-month period for support and follow-up counseling. Participants will continue to monitor BP measurement by logging BP data on BP diary book for another 12 months. Control group participants will receive the same intervention education following the completion of the study.

2

Wait-list control group will initially receive usual care from a regular medical provider. Participants in the control group will take part in the intervention once the study has been completed.
