In recent years, researchers and policymakers have recognized that
obesity in childhood is not simply a medical problem, but is a complex social
and psychological phenomenon. Our research team used an interpersonal and
intrapersonal risk model to examine the psychosocial aspects of obesity among
rural children. In this article, we describe how the global study of
children’s obesity has broadened over the last 10 to 15 years, and we
present our model of interpersonal and intrapersonal risk factors, which
includes complex pathways with many psychosocial variables. We then describe a
large prospective longitudinal study of children in grades 1 through 4, and
highlight findings from five studies guided by this model. This work illustrates
opportunities for developmental scientists and practitioners to join
transdisciplinary teams to develop more effective prevention and intervention
programs for children.
