Adverse Childhood Experiences Associated with Greater Internalization of Weight Stigma in Women with Excess Weight.

Adverse childhood experiences (ACEs) may be an early life factor associated with adult weight stigma via biological (e.g., stress response), cognitive (e.g., self-criticism/deprecation), and/or emotional (e.g., shame) mechanisms. This pilot study investigated relationships between ACEs and internalized and experienced weight stigma in adult women with overweight/obesity and explored differential relationships between weight stigma and ACE subtypes (i.e., abuse, neglect, household dysfunction). Adult women (68% white, M _age = 33 ± 10 years, M _BMI = 33.7 ± 7.2 kg/m²) completed measures of ACEs (ACE Questionnaire), internalized weight stigma (IWS; Weight Bias Internalization Scale-Modified; WBIS-M), and lifetime experiences of weight stigma (yes/no). Data were analyzed with linear and logistic regression (n = 46), adjusting for age, race, and body mass index (BMI). Linear regressions revealed a positive association between ACE and WBIS-M scores (β = 0.40, p = 0.006), which was driven by Abuse-type ACEs (β = 0.48, p = 0.009). Relationships between WBIS-M scores and Neglect- and Household-Dysfunction-type ACEs did not reach significance (β = 0.20, p = 0.173; β = -0.16, p = 0.273). Though descriptive statistics revealed greater rates of experienced weight stigma endorsement by those with high-3+ ACEs (81%) vs. medium-1-2 ACEs (67%) or low/no-0 ACEs (60%), ACE scores were not significantly associated with experienced weight stigma in logistic regression (Wald = 1.36, p = 0.244, OR = 1.324, 95%, CI = 0.825-2.125). ACEs may be an early life factor that increase the risk for internalizing weight stigma in adulthood. Larger studies should confirm this relationship and follow-up on descriptive findings suggesting a potential association between ACEs and experienced weight stigma.
