Abstract |
Childhood maltreatment is consistently associated with adult obesity, leading to calls for tailored weight interventions for people with maltreatment histories. However, it is possible that the maltreatment-obesity association is spurious and driven by unmeasured confounding, in which case such interventions would be misplaced. The home food environment in childhood is a potential confounder, but its role in the association of maltreatment with obesity has not been examined. We used a longitudinal dataset (Project EAT) to examine the association of adult retrospective reports of maltreatment history in childhood (1+ types of maltreatment before age 18 years) with previously-collected prospective childhood reports of home food environment characteristics (availability of healthy foods, availability of sweet/salty snack food, family meal frequency, and food insufficiency). We then estimated the association between maltreatment and adult body mass index (BMI, kg/m2) with and without adjustment for these home food environment factors. After adjustment for sociodemographics, maltreatment had a 0.84 kg/m2 (95% CI: 0.28, 1.41) higher BMI at age 24-39 years, compared to those with no maltreatment, after adjustment for sociodemographics, parenting style, and BMI in childhood. Additional adjustment for home food environment factors had little effect on this association (β = 0.78 kg/m2; 95% CI: 0.21,1.35), suggesting limited confounding influence of the home food environment factors. Findings provide additional robust evidence that childhood maltreatment is a risk factor for obesity that may warrant tailored interventions. Language: en |
