Abstract MP12: Residential Relocation by Older Adults in Response to Incident Cardiovascular Health Events
Background: Despite the potential public health importance of local infrastructure to support healthy aging, our understanding of causal relationships between place of residence and health is complicated by the potential for health changes to precipitate relocation to a new home.
Objectives: Quantify the effect of health on residential mobility to create a foundation for studying local resources supporting aging in place, as well as assess the potential for reverse causation bias in studies of neighborhood or household features and the health of older adults.
Methods: We conducted an ambidirectional case-crossover analysis of data form the Cardiovascular Health Study (CHS), a community-based prospective cohort study of 5,888 older adults from four U.S. sites beginning in 1989. Adjudicated cardiovascular disease events and procedures were considered as potential triggers for residential relocation, defined as a move from the participant’s previous residence. Participant relocation in the past 6 months (or 1 month) was assessed at baseline and then twice a year during most of the follow-up period through 2006. Event occurrences were classified as present or absent for the 12-month (or 2 month) period preceding the first report of the first move, as compared with an equal length of time immediately prior to and following this period.
Results: Older adults (65+) that experience incident cardiovascular disease had an increased probability of subsequently changing their residence during the following year (OR 1.5, 95% confidence interval (CI) = 1.1-1.9). Clinical conditions associated with relocation included stroke (OR: 2.0, 95% CI: 1.2-3.3), angina (OR 1.6, 95% CI=1.0-2.6) and congestive heart failure (OR 1.5, 95% CI=1.0-2.1).
Conclusions: Major incident cardiovascular disease increased the probability of residential relocation in older adults.
