Residential mobility and long-term treatment of hypertension.

Maintenance of long-term care of populations with high mobility patterns poses problems for programs designed to prevent and treat cardiovascular and other chronic diseases. The Hypertension Detection and Follow-up Program (HDFP)--a community-based screening and treatment program implemented in 1973--provided an opportunity to examine residential mobility among adults under long-term treatment in 13 communities. Whereas 11% of hypertensives included in the HDFP changed residence in the first two years of the study, only 4% moved outside the service areas of the programs. Although a higher proportion of blacks (to whites) moved within the service areas, a similar proportion moved outside the service areas. This low residential mobility, especially the low rate of movement outside the service areas of the treatment centers, suggests that mobility of cohorts under long-term treatment and observation may present lesser problems to continuous, long-term community health care programs than do other factors affecting adherence.
