12 - Family history of cardiovascular disease is associated with self-reported cognitive function: the Emory Healthy Aging Study

Background: Family history of cardiovascular disease (FHxCVD) is a CVD risk indicator that captures the influence of genetic and shared familial factors and is readily available to individuals and clinicians. Though CVD risk factors associate with greater risk of cognitive impairment, less is known about the association between FHxCVD and self-reported cognitive function. Evaluating this association may further elucidate links between cardiovascular and cognitive health.


 



Methods:
The Emory Healthy Aging Study isa community-based prospective cohort study aimed at identifying predictors of healthy aging and age-related diseases. Participants are primarily residents of the Atlanta area, at least 18 years old, who completed an online baseline health survey. Information about demographic (age, self-reported race, gender), socioeconomic (education, household income), lifestyle (physical activity, smoking) and CVD risk factors (diabetes, hyperlipidemia, BMI, hypertension) and family health history were collected at enrollment. Family history of CVD was defined as self-reported history of coronary artery disease, myocardial infarction, or stroke for any biological parent or sibling. Self-reported cognitive function was measured using the validated Cognitive Function Instrument (CFI) and categorized into quartiles. Associations between FHxCVD and CFI score quartile were assessed using multinomial logistic regression, adjusting for demographic, socioeconomic, lifestyle and the participant’s own CVD risk factors, as well as family history of any diagnosed cognitive impairment.


 



Results:
We studied 6,115 participants (75% female, 84% white, 11% black, and 5% other self-reported race), without existing CVD, recruited between October 2015 and 2017. Mean age was 59±13 years and 61% reported a family history of CVD. Comparing extreme quartiles of CFI score, adjusted for demographic, socioeconomic, and lifestyle factors, plus family history of any diagnosed cognitive impairment, FHxCVD was associated with poorer self-reported cognitive function (OR=1.43; 95% CI (1.21, 1.70)). The OR after additional adjustment for CVD risk factors was not meaningfully different (OR=1.47; 95% CI (1.23, 1.76)). In the same fully adjusted model, the estimated OR for family history of any cognitive impairment was slightly larger: 1.54 (1.30, 1.83).


 



Conclusion:
In this cross-sectional community sample, family history of CVD was associated with poorer self-reported cognitive function, and this association was of a similar magnitude as having a family history of cognitive impairment. Although longitudinal studies are needed, these results underscore the link between cardiovascular and cognitive health. Twin studies are needed to estimate the contribution of genetic and shared familial factors.

She has over 20 years experience conducting large epidemiologic cohort studies. Dr. Marcus received her MPH and PhD in Epidemiology at Columbia University as well as completing a fellowship in Neuroepidemiology. As Assistant Director of the Center for Health Research for Kaiser Permanente Georgia, she established a biobank with 85% participation of African American and Caucasian women and served on the Leadership Team for Kaiser’s National Biobanking efforts. She has been invited to speak at national and regional IRB organization meetings concerning ethical issues of biobanking and studying genetic information. She has received continuous federal funding for nearly 20 years as PI of a long-term follow-up study of individuals exposed to toxicant-contaminated food. This cohort study now contains multiple generations and strong community involvement. She has published extensively on multi-generational health effects utilizing several cohorts including the Avon Longitudinal Study of Parents and Children. Dr. Marcus has conducted several federally-funded studies evaluating psychosocial stress and ergonomic stress as predictors of adverse musculoskeletal health outcomes and a randomized clinical trial of an ergonomic intervention. She has contributed to the scientific literature in multiple areas of cohort research from recruitment and community engagement to data collection and analyses.

Dr. Marcus has served on federal expert panels reviewing health effects of electromagnetic fields, bisphenol A, phthalates, gene/environment interactions and service in the Persian Gulf War. She served on the National Academy of Sciences Institute of Medicine Committee on dioxin exposure among Vietnam Veterans. She has studied the health consequences of various exposures including psychosocial stress, PCBs, PBBs, PFCs and electromagnetic fields.

Dr. Marcus has served in many additional leadership positions including Director of Graduate Studies and Interim Chair for the Department of Epidemiology and Co-Director of the Southeast Pediatric Environmental Health Specialty Unit. Her research on multi-generational health effects has been recognized with awards from the CDC and the EPA. She currently serves on the Leadership Team for the Emory Healthy Aging Study.
