title: Design and baseline characteristics of a hypertension intervention program in a South African village.
abstract: The Mamre Hypertension Project was initiated in response to studies indicating that hypertension and cardiovascular disease were prevalent in a rural community of Mamre, located in the Western Cape, South Africa. A survey was done to collect baseline information on the prevalence of hypertension and other cardiovascular disease risk factors. The age-adjusted prevalence of hypertension in people aged 15 years or more was 13.9% in men and 16.3% in women. Of the hypertensive subjects, 27% were not aware of their hypertension, a further 14.4% were not on treatment, and only 16.8% had their blood pressure (BP) controlled at under 140/90 mm Hg. There was a high prevalence of smoking, heavy alcohol use (in men), obesity (in women) and physical inactivity. The survey results will be used to assess the impact of the intervention programme using a before and after design, and are being used to direct interventions. The intervention programme comprises a BP station catering primarily for people with hypertension, and a health education and promotion programme directed at the general community. The BP station screens for hypertension, monitors BP and compliance with medication in hypertensives, and encourages risk factor modification. Health promotion activities include a smoking cessation group and a weight reduction and exercise group. These are run by community volunteers with support from outside consultants. The effects of the programme will be assessed after 4-5 years.
