Hypertension (HTN), a major health problem in the US, is the most prevalent modifiable risk factor for cardio-vascular disease (CVD), the leading killer of women. The incidence of HTN in women increases markedly after menopause, equaling or exceeding that in men. The prehypertension category of blood pressure (BP) -- systolic BP of 120-139 mm Hg or diastolic BP of 80-89 mm Hg -- designates individuals at high risk of developing HTN. Prehypertensive women are not candidates for drug therapy, but for lifestyle modifications to prevent progression to HTN and CVD. Recommended lifestyle modifications include adoption of the Dietary Approaches to Stop Hypertension (DASH) diet that is high in fruits, vegetables and low fat dairy products; dietary sodium reduction; regular endurance physical activity supplemented by resistance exercise; and weight reduction by those who are overweight or obese. A few studies of face-to-face individual and/or group interventions have demonstrated that these lifestyle modifications could lower BP over 6 months in pre-hypertensive individuals. There remains a need to develop distance delivery methods to target rural women with similar behavioral interventions to lower BP. This competitive renewal application will build upon our current work in which we demonstrated that computer-generated print (mailed) newsletters tailored to constructs in the Health Promotion Model (HPM) resulted in significant and clinically important changes in behavioral and biomarkers of healthy eating and physical activity in a general population of rural midlife/older women. The proposed randomized controlled trial will evaluate Internet versus mailed print delivery methods for delivering theory-based tailored newsletters to encourage lifestyle change for BP reduction. A sample of 275 prehypertensive rural women aged 50-69 will be randomly assigned 2:2:1 to receive a) tailored messages delivered via the Internet and brief telephone counseling, b) tailored print newsletters delivered via mail and brief telephone counseling, or c) initial standard advice only. Results of this study may lead to expanded access to lifestyle guidance via the Internet by other populations.
