Подробное описание
We propose a randomized controlled trial to evaluate the effect of telephone-delivered interventions (SMI and HEI) to improve BP control.
Veterans with uncontrolled hypertension (n=533) will be randomized equally to 3 groups: 1) The SMI will use the Transtheoretical model (TTM) as the unifying framework. Veterans will receive TTM stage-matched counseling for exercise, diet, and medications via monthly counseling sessions. A social worker (SW) will assess each participant's behavior and deliver the appropriate tailored SMI based on their stage of change, decisional balance, self-efficacy and the skills model questions. 2) The HEI group receives monthly telephone calls by a SW during which they will receive education about hypertension management. 3) The UC group participates in all the in-person visits but does not receive monthly calls.
There will be an initial 6-month active intervention phase followed by a 6 month monitoring phase to assess sustainability. All participants will visit the VAMC's at baseline and at 3, 6, and 12 months. Outcomes of interest include BP; adherence (to diet, exercise and medications); quality of life; satisfaction; acceptability; cost and cost-effectiveness. Patients will be blinded to which of the intervention arms (SMI or HEI) they are in, SW's will be blinded to patient's BP and staff measuring outcomes will be blinded to study assignment. The study will be analyzed using longitudinal data analysis methods using an intention to treat strategy.

Diet Stage of Change
Временное ограничение: 6 months
|
The stages of change were: precontemplation, or no plans to adhere in <6 months; contemplation, or plans to adhere in 1-6 months; preparation, or plans to adhere within 1 month; action, or adherence for <6 months; and maintenance, or adherence for ≥ 6 months.
Patients were considered adherent to diet if they reported eating the appropriate diet for hypertension (low in salt and fat with fruits, vegetables, and low-or non-fat dairy products) at least 6 days per week.

Exercise Stage of Change
Временное ограничение: 6 months
|
The stages of change were: precontemplation, or no plans to adhere in <6 months; contemplation, or plans to adhere in 1-6 months; preparation, or plans to adhere within 1 month; action, or adherence for <6 months; and maintenance, or adherence for ≥ 6 months.
Exercise adherence was defined as self-reported aerobic exercise for at least 3 days per week for at least 20 minutes each time.
We used the lower threshold for exercise adherence due to our patient population with multiple comorbidities, consistent with Federal guidelines for older adults with chronic conditions.

Medication adherence was defined as self-report of taking BP medications as prescribed for at least 6 days per week.
