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

Condition or disease Intervention/treatment Phase
Pre-Hypertension Behavioral: Lifestyle modification Not Applicable

Detailed Description:

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.
