BackgroundNo study has evaluated whether genetic factors are associated with longevity in African Americans or Hispanics, and it is unclear whether genetic factors are associated with healthy aging.
MethodsIn this prospective study, we determined whether 14 genetic variants previously associated with longevity in genome-wide association studies were associated with survival to ages 85 and 90 in 11,053 postmenopausal white, African American, and Hispanic women from the Women's Health Initiative. The associations of these variants with healthy aging, defined as survival to age 85 without chronic diseases or disability, were also determined.
ResultsAmong white women, three single nucleotide polymorphisms (SNPs) (rs2075650 [TOMM40], rs4420638 [APOC1], and rs429358 [APOE]) were significantly associated with survival to 90 years after correction for multiple testing (p < .001); rs4420638 and rs429358 were also significantly associated with healthy aging (p = .02). In African American women, no SNP was associated with longevity. In Hispanic women, 7 SNPs in linkage disequilibrium with a novel SNP, rs2149954, recently identified as being associated with increased longevity in a European population, were significantly associated with decreased survival to age 85 for carriers of the T versus C allele (p = .04). The association with decreased longevity was explained by higher risk of coronary heart disease in carriers of the T allele. There were no associations between FOXO3A SNPs and longevity in the analyses. In a meta-analysis, rs2075650 and rs429358 were significantly associated with longevity.
ConclusionsFuture studies are needed to identify novel loci associated with longevity in African American and Hispanic women to determine biologic pathways regulating life span in these groups.
