Extract

To the Editor We read with great interest the article “Genetic Differential Susceptibility to Socioeconomic Status and Childhood Obesogenic Behavior: Why Targeted Prevention May Be the Best Societal Investment,” by Silveira et al.1 In this study, the authors found that girls carrying the 7-repeat allele of DRD4 who were from a low-income bracket had increased fat intake compared with noncarriers. Similarly, girls carrying the 7-repeat allele of DRD4 who were from families with a higher income bracket had decreased fat intake compared with noncarriers. The authors postulated that the 7-repeat allele of DRD4 might not simply indicate increased susceptibility to obesity but actually be a plasticity allele that might be advantageous in more favorable settings but obesogenic in adversity.
