Abstract
We estimated the proportion of subSaharan African AFR Amerindian AMI and European admixture using 92 ancestryinformative marker genotypes in 16476 AFA and HA women from the Women’s Health Initiative Cox regression models were used to examine the association between admixture and diabetes risk with and without accounting for socioeconomic status SES and adiposity measurementsAFR admixture was significantly associated with diabetes risk in AFA women when adjusting for entry age neighbourhood SES and BMI or waist/hip ratio WHR all p 00001 In HA women AMI admixture had significant associations with diabetes risk that remained significant after adjustment for SES and BMI all p 00005 In both AFAs and HAs SES showed significant negative associations while BMI or WHR had significant positive associations with diabetes risk with and without adjustment for genetic admixtureIn AFAs admixture SES and BMI/WHR each independently contribute to diabetes risk after accounting for each of the other factors in HAs admixture SES and BMI each independently contribute to diabetes risk after accounting for each of the other factors whereas admixture is not significantly associated with diabetes risk after accounting for SES and WHR The findings emphasise the importance of considering both genetic and environmental causes in the aetiology of type 2 diabetes
