Study of Hispanics to Assess Risk Prevention in Prehypertension

Lifestyle Intervention in Multinational Hispanics With Prehypertension

The purpose of this study is to assess the efficacy of lifestyle modification in reducing blood pressure values in Hispanics at risk for hypertension.

In this study participants (who have prehypertension as defined as systolic blood pressure - the upper number- 130-139 mmHg and diastolic blood pressure 85-89mmHg- the lower number-) are randomly assigned to one of two groups:

the Minimal Intervention Group- participants receive advice and printed guidelines only but no counseling or personalized instruction, or the Enhanced Intervention Group- participants receive advice and the same printed guidelines as the minimal intervention group, together with dietary and physical activity counseling provided by a dietician and/or coordinator, periodic professional reviews of their progress and personalized instructions.

• Hispanic men and women age 18 or older
