ALL consists of all self– identified African American (AFA) and Hispanic Americans (HA) participants; AFA consists of self– identified AFA participants; AFA subgroup consists of the self– identified AFA with >0.2 AFR and <0.05 AMI admixture; HA consists of self– identified HA participants; HA subgroup consists of the self– identified HA with >0.1 AMI and <0.1 AFR admixture.
The odds ratio (OR) attributed to a unit (0 to 100%) increase in admixture. For these analyses the top and bottom quartiles were compared and the OR reflects the increased or decreased risk for higher adiposity measurement attributed to admixture of the indicated continental contribution. Analysis was performed using the following covariates: age at entry, smoking, education, income, parity and physical activity.
