Do Nutritional Factors Influence Externalizing Behavior during Early Childhood? : A Genetically Informed Analysis

Moffitt's (1993) taxonomy of adolescence-limited and life-course-persistent offenders suggests, among other things, that an early onset of antisocial behavior a) increases the likelihood of a life-course persistent offending trajectory and b) is the product of neuropsychological deficits and familial risk factors working in concert. Over two decades of research has yielded a substantial amount of support for Moffitt's claims. Nevertheless, research has yet to significantly expand the repertoire of biosocial processes that might influence the onset of antisocial behavior during childhood. For instance, only a handful of criminologists have considered the role that infant and early childhood nutrition might play in the development of antisocial behavior. Moreover, studies employing genetically sensitive methods to examine the link between nutrition and child antisocial behavior are virtually nonexistent. Scholars have also neglected to consider the socioemotional mediators of the nutrition-externalizing relationship, as well as whether infants and children are differentially sensitive to nutritional intake depending on their level of genetic risk, perinatal risk, and security of attachment. Finally, researchers have yet to explore the ways in which nutritional factors across infancy and early childhood work together to influence externalizing behavior. This dissertation seeks to address these gaps in the literature by employing a large, nationally representative sample of twin pairs. The findings suggest that, even after accounting for the influence of genes and the shared environment, nutritional factors during infancy and early childhood have both direct and indirect effects on externalizing behavior during kindergarten. Furthermore, some significant interactions between genetic and nutritional factors, as well as nutritional factors across life stages, were detected. The limitations of the study are noted and recommendations for policy, theory, and future research are discussed. / A Dissertation submitted to the College of Criminology and Criminal Justice in partial fulfillment of the requirements for the degree of Doctor of Philosophy. / Summer Semester, 2015. / May 22, 2015. / Antisocial, Attachment, Breastfeeding, Diet, Genetics / Includes bibliographical references. / Kevin M.
