Objective:
The Framingham risk score is a well-established tool used to estimate the 10-year cardiovascular disease (CVD) risk of an individual. Cross-sectional studies have established that higher risk scores are associated with poorer cognitive functioning, though there are fewer longitudinal studies to determine impact on this study is to investigate the association between the Framingham CVD risk score and cognitive functioning 10 years later among a community-dwelling sample of older adults.
Participants and Methods:
Participants (N= 588; Age M̄ =1.7, Female= 59.6%, Non-Hispanic Black 40.0%, Hispanic/Latinx=10.4%, Education M=14.7) completed Phase 2 of the Dallas Heart Study (DHS-2; Time 1) and returned approximately 10 years later for Phase 3 (Time 2). At Time 1, a (Range: 1-25; M̄= 3.4. SD=4.5) was calculated based on age, sex, cholesterol, glucose, and hemoglobin levels (obtained from a lab sequence), history of hypertension, blood pressure readings, presence/absence of diabetes, and smoking status. Participants were administered the Montreal Cognitive Assessment (MoCA) at baseline. At Time 2, a cognitive battery that included the MoCA, Wechsler Test of Adult Reading (WTAR), CERAD list-learning task, Trails A&B, Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV) , and Animal Fluency was conducted. were calculated for each test. MoCA was calculated as the ratio of change in MoCA total score over baseline total score. A series of multiple linear were conducted to determine if baseline CVD risk scores were associated with cognitive performance at Time 2.
Results:
Of the total sample at Time 1, were hypertensive, and 28.1% were hypercholesterolemic Eighty-eight percent of participants were classified as low (<10% chance of developing CVD), 7.3% were moderate risk (10-20%), and 1.6% were high risk (>20%). Regression analyses revealed that higher Framingham CVD risk scores were associated with performance on CERAD total words (β=-0.29, p<.001) and Trails-B (β=0.11, p<.05), and predicted a larger reduction in MoCA total scores (β=0.14, p<.05) from Time 1 to Time 2 controlling for age, sex, ethnoracial group, estimated intelligence, and .
Conclusions:
This study evaluated the association of Framingham risk scores with cognitive performance 10 years later in a probabilistic community sample. previous literature, significant associations were found between. This is particularly noteworthy given that the sample contained predominantly low risk individuals. Future research may benefit from examining trajectories of cognitive decline by baseline level of CVD risk (i.e., low, medium, high) to better understand what threshold of CVD risk is most likely to be associated with future cognitive decline.
