Review of literature indicates that obesity is on the rise nationally and obese individuals are at inherent risk for a variety of comorbid physical, psychological, and social problems which often result in significant functional impairment due to sequelae. Previous research suggests a meaningful association between obesity and greater internalizing difficulties typically manifested by symptoms of depression and anxiety (Faith, Matz, & Jorge, 2002; Scott et al., 2008; Stunkard, Faith, & Allison, 2003; Zhao, Ford, Dhingra, Strine, & Mokdad, 2009). In recent years, there has been emerging interest in exploring the relationship between obesity and individuals with externalizing problems including aggression, …

Background—Earlier studies have established that a substantial percentage of variance in obesity-related phenotypes is explained by genetic components. However, only one study has used both virtual twins (VTs) and biological twins and was able to simultaneously estimate additive genetic, non-additive genetic, shared environmental and unshared environmental components in body mass index (BMI). Our current goal was to re-estimate four components of variance in BMI, applying a more rigorous model to biological and virtual multiples with additional data. Virtual multiples share the same family environment, offering unique opportunities to estimate common environmental influence on phenotypes that cannot be separated from …
