Studies of the association between various factors and blood pressure in different populations have shown the occurrence of specific dietary factors associated with elevated blood pressures. The factors include overweight, alcohol consumption and high sodium intake. Heart rate is also an independent predictor of risk of hypertension. Diet and exercise are amenable to intervention to influence blood pressure with the aim of reducing the risk of developing hypertension.\n\nDESIGN NARRATIVE:\n\nIn the first phase of the trial participants were randomized to a Monitored (Control) Group or to an Intervention Group receiving individualized intervention to achieve changes in diet and physical activity. The goals of the Intervention Group were: a reduction of at least 10 pounds or 5 percent of body weight for those above desirable weight; a reduction in daily sodium intake to 1800 mg; a modification of alcohol intake to no more than two drinks per day; and an increase in regular, moderate physical activity. The primary endpoint in the first phase of the trial was the comparison of mean blood pressure in the Intervention Group versus the Monitored Group. In the second phase of the trial, all randomized participants were followed for a minimum of five years. The primary endpoints in the second phase were the incidence of high blood pressure and/or hypertension."}, "EligibilityModule"=>{"Gender"=>"All", "MaximumAge"=>"44 years", "MinimumAge"=>"30 years", "StdAgeList"=>{"StdAge"=>["Adult"]}, "HealthyVolunteers"=>"No", "EligibilityCriteria"=>"Men and women, ages 30 to 44.
