Introduction: Public health efforts to curb the obesity epidemic in the United States have shifted focus towards obesity prevention strategies in early stages of life. While most studies examining the etiology of excess weight gain in childhood have focused on behavioral factors, like dietary intake and physical activity, recent literature suggests prevention strategies may benefit from targeting complex interactions between children, their caregivers, and the broader social and material context of family home environments. In response, obesity preventions researchers are considering the potential influence of chaos in childhood obesity risk, as well as the role of caregiver-child interactions in healthy weight development; very few studies have simultaneously considered chaos and caregiver-child interactions in the context of childhood obesity risk. Thus, the current dissertation aimed to examine risk pathways from chaos to childhood obesity directly, and through aspects of caregiver-child feeding interactions. All studies included in this dissertation use data from the Play & Grow study, a contemporary cohort of caregiver-toddler dyads (N = 299) from central Ohio. The cohort was constructed to examine children's weight trajectories in early childhood, with respect to caregiver-child mealtime and play time interactions, children's self-regulation, and children's gestational age.
Study 1: Chaos has implications for child health that may extend to childhood obesity. Yet, results from studies describing associations between chaos and childhood obesity are mixed. Challenges to studying chaos-obesity relationships may include inconsistencies in operationalizing chaos and reliance on caregiver perceptions. Furthermore, multiple pathways may link chaos to obesity, though few have been empirically examined. A concurrent mixed methods analysis was conducted to describe home and neighborhood chaos using a subsample 283 caregiver-toddlers dyads from the Play & Grow study.
