[The Lyons Hypertension Control Program (1972-1978). Community analysis].

A Community Control Program of Hypertension was undertaken in Lyon, as part of a WHO program. It dealed with two occupational, Study (S) and Reference (R), communities, each amounting to about 12,500 subjects. Its goal was to improve the level of treatment of hypertension in S, by stimulating the usual health care system without modifying it. It began in 1972 by a baseline total survey of both communities. Its aim was to check that the percentage of treated hypertensive subjects (HT) was the same in S and R (respectively 10.9% and 11.7%, n.s.), and to detect all HT's (subject being given an antihypertensive drug treatment, and/or BP greater than or equal to 160 and/or 94, or greater than or equal to 150 and/or 90 before age 30). The S intervention involved: detection of "new HT's" during the whole program; information of HT's, and referral to the treating physician of their choice, who was informed about the aim of the program and received later periodic information about hypertension management; periodic follow-up reconvocations. A leaflet including advices for C-V prevention was distributed to the whole S community in 1976. Evaluation was performed by a terminal total survey of both communities, from 1977 to 6/1978 (examination rates: 94.4 and 91.6% in S and R). The evaluation involved two analysis of 1977 data. -Cohort analysis (reported before): the percentage of treated HT's in the cohorts of 1972 HT's, still present in the community and hypertensive, was higher in S (63.0) than in R (46.1) (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
