The effect of a community hypertension control program.
A hypertension detection and control program sponsored by the Pan-American Health Organization and the World Health Organization (PAHO/WHO) was carried out in an urban health district of Havana City, Cuba. A baseline (initial) survey was conducted on a random sample of the population (greater than or equal to 15 years of age) to assess the problem of hypertension in that community. Subsequently, we extended the program in the same area by taking the blood pressure of as many people as we could, and a health education program on hypertension was developed and implemented. All hypertensive persons were treated. We surveyed about 90% of the adult population (29,640) over a 5-year period. We then conducted a final survey on a second random sample of the population to assess the effect of the program. The response rate to the letter of invitation to visit the hypertension clinic was 50%; 30% of the recall appointments were missed, and the dropout rate was 18.6%. Seventy percent of the hypertensive persons had Stage I disease (PAHO/WHO) with normal electrocardiograms. Before the program, 15.7% of the total number of hypertensive persons surveyed in the area had the disease under good control, and this increased to 31% after the program. Mortality due to cerebrovascular disease was reduced from 11/10,000/yr to 7/10,000/yr, whereas mortality caused by myocardial infarction did not change.
