Blood Pressure Studies in 14 Communities

the Hypertension Detection and Follow-up Program (HDFP) is a community-based national trial to determine whether special programs can improve the treatment for persons with uncontrolled hypertension and reduce morbidity and mortality in wide strata of these patients. A total of 158,906 persons, aged 30 to 69 years, were screened to identify those with a diastolic blood pressure (DBP) of 95 mm Hg or higher. Age-sex-race means and distributions of DBP at a first and a second screen and prevalence rates or actual hypertension by sex, race, and level of control suggest a recently increased awareness of hypertension with more widespread and effective treatment, especially among women, although blacks under treatment had their DBP controlled less frequently. The response to this program of screening and initial follow-up offers encouragement for improved community control of high blood pressure.
