Genetic associations with body-mass index and obesity among black young adults in the Add Health Sibling Pairs Sample estimated using the genetic risk scores for Europeans (GRS-E), African Americans (GRS-A), and the composite genetic risk score (GRS-Omni).

<p>* p<.05; ** p<.01; *** p<.001.</p><p>Note: All data come from the National Longitudinal Study of Adolescent Health Sibling Pairs <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0101596#pone.0101596-Harris1" target="_blank">[17]</a>. Regressions were estimated using multi-level models <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0101596#pone.0101596-Raudenbush1" target="_blank">[20]</a> to account for the clustering of observations within families and adjusted for age and sex. Change models were estimated by including Wave 3 outcomes as covariates in regression models predicting Wave 4 outcomes.
