Nearly 13% of children in the United States have a confirmed case of physical abuse, sexual abuse, or neglect committed by a caregiver, and thousands of additional cases go unreported. Maltreated children have heightened risks for poor health outcomes later in life, including obesity. The significant between-person variability in BMI trajectories from adolescence to young adulthood indicates the presence of moderators that may explain susceptibility and resilience to the effects of child maltreatment on later BMI trajectories, and mediators may explain why the relationship exists. The objectives of this dissertation were to succinctly characterize BMI trajectories using a novel analytic method (Paper 1) and to understand how social support and stress responses influence the relationship between child maltreatment experiences and BMI trajectories from adolescence to adulthood (Papers 2 and 3). I addressed these objectives with structural equation modeling using the National Longitudinal Study of Adolescent to Adult Health. The analytic sample included 17,669 respondents, of which 32% experienced child maltreatment before age 13. I first developed and validated a parsimonious measure of BMI trajectories that captures an individual's average deviance above a healthy BMI over a specified period-average excess BMI. Next, I found maltreatment that began in childhood was not significantly associated with average excess BMI from adolescence to adulthood; adolescent-onset child maltreatment, however, was positively associated with average excess BMI (B = 0.28, s.e. = 0.11, p = 0.01). Lastly, I found no evidence of social supports (i.e., peer friendships and adult mentors) moderating, or stress responses (i.e., depressive symptoms and impulsivity) mediating, the relationship between childhood-onset child maltreatment experiences and BMI trajectories (ps > 0.05). Friendships were protective, however, against higher average excess BMI for all individuals (B = -0.082, s.e. = 0.02, p < 0.001). In addition to providing a new longitudinal BMI measure for use in clinical and research settings, this dissertation suggests that leveraging friendships may be an effective obesity prevention effort among youth.
