Among EA participants, higher LS7 scores were consistently associated with lower risk of dementia across quintiles of GRS, including the highest quintile (HR per point 0.91, 95% CI 0.87, 0.96). Among AA participants, the associations between LS7 and incident dementia within stratum of GRS had the same direction as among EA participants, although wide CIs and smaller sample sizes limited reliable inferences.Discussion Across strata of GRS, higher midlife LS7 scores were associated with lower risk of dementia. Larger sample sizes from diverse populations are needed to obtain more reliable estimates of the effects of modifiable health factors on dementia risk within genetic risk strata in each ancestry group.AA=African American; AD=Alzheimer disease; AHA=American Heart Association; ARIC=Atherosclerosis Risk in Communities; BioLINCC=Biologic Specimen and Data Repository Information Coordinating Center; CVD=cardiovascular disease; DSM-5=Diagnostic and Statistical Manual of Mental Disorders, 5th Edition; EA=European American; FINGER=Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability; GRS=genetic risk scores; GWAS=genome-wide association studies; HR=hazard ratio; ICD-9=International Classification of Diseases–9; LS7=Life's Simple 7; PC=principal component; SBP=systolic blood pressure; SNP=single nucleotide polymorphism; TICS=Telephone Interview for Cognitive Status
