Hypertension
Conditions
Brief summary
The aim of this study is to assess the efficacy of Telephone-Linked\_Care for Hypertension Regimen Adherence in an African American population (TLC-HTN-AA). TLC-HTN-AA is a computer-based telecommunication system that will monitor, educate and counsel African American adults with hypertension on adherence to medication, diet, and exercise. The primary hypotheses are: 1. TLC-HTN-AA use will improve medication regiment adherence 2. TLC-HTN-AA will improve adherence to 3 healthy diet recommendations 3. TLC-HTN-AA will improve levels of regular exercise 4. Patients receiving TLC-HTN-AA will be more likely to become adherent to all 3 target regiments than patients in the control group
Interventions
BEHAVIORALAutomated Telephone Program
The intervention incorporated principles of social cognitive theory, the transtheoretical model of behavioral change, and motivational interviewing, and was tailored to the user's values. Content was also adapted to cultural characteristics of culturally African-American adults (i.e., not Caribbean-American, Black-Hispanic, etc.). These participants also received the same health behavior education those in the control condition received.
BEHAVIORALHealth Behavior Education
Participants received a 75-page resource manual that described hypertension, listed dietary recommendations, heart healthy food recipes, and local resources for exercise, and provided information to support antihypertensive medication adherence. They received a 20-min education session based on the content of this manual, and were given a pedometer and a digital weight scale (Healthometer, model # HDR900KD01).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 1-proportion of study subjects who achieve adequate adherence (greater than or equal to 80% of doses taken) at the end of the intervention period | 8 months | Outcomes were assessed at baseline, 4 months, 8 months (the end of the study intervention) and 12 months. |
| 2-consumption of more than 5 servings of fruits and vegetables a day, less than 30% of calories from fat, and less than 2400 mg of sodium a day at the end of the intervention period | 8 months | Outcomes were assessed at baseline, 4 months, 8 months (the end of the study intervention) and 12 months. |
| 3-adherence to CDC-ACSM recommendations for moderate intensity physical activity at the end of the intervention period | 8 months | Outcomes were assessed at baseline, 4 months, 8 months (the end of the study intervention) and 12 months. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 1-TLC-HTN-AA use will reduce the mean blood pressure and the proportion of the treatment group having uncontrolled hypertension at the end of the intervention period | 8 months | Outcomes were assessed at baseline, 4 months, 8 months (the end of the study intervention) and 12 months. |
