INTRODUCTIONVascular risk factors contribute to cognitive decline and dementia; however, research across populations remains scarce. METHODSWe included 402 participants (mean age 57.9{+/-}3.8, 58.5% female, 52% Mexican American). Midlife cardiovascular health was assessed using the AHA Lifes Simple 7 (LS7). General cognition was measured four times over a period of 9.5 years. We used generalized estimating equations to assess the association of LS7 scores and its factors with cognitive change, overall and by ethnicity. RESULTSMeeting intermediate or ideal physical activity goals mitigated cognitive decline, particularly in Mexican Americans, and maintaining blood glucose below 125 mg/dL was associated with slower cognitive decline among non-Hispanic Whites. Additionally, Mexican Americans with a BMI <30 kg/m2 showed an accelerated cognitive decline. No associations were observed between total LS7 scores and cognitive decline. DISCUSSIONPhysical activity, blood glucose, and BMI have distinct contributions to cognitive change across different ethnicities.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
