[Clinical effect of lifestyle modification on cardiovascular risk in prehypertensives: PREHIPER I study].

The objective was to determine the effect of lifestyle modification on cardiovascular risk in individuals with prehypertension, which is defined as a systolic blood pressure between 120 mmHg and 139 mmHg and a diastolic pressure between 80 mmHg and 89 mmHg. A randomized clinical trial was carried out in prehypertensives to compare those who took part in a program involving dietary modification, physical activity and educational sessions with those who followed normal recommendations. Cardiovascular risk was evaluated using the Framingham risk score and the chi-squared test, the Mann-Whitney U-test and the Friedman test.
