Objective: Traumatic events, including abuse, neglect, and other dangerous/shocking experiences, are commonly observed in adolescents with T2D. Research has shown there is a link between trauma and poorer health outcomes, yet, the extent to which trauma increases risk for developing T2D is not well understood. Trauma may heighten T2D risk through LOC eating, which can arise to cope with negative emotions. Our aim was to evaluate the links of trauma and LOC eating with T2D risk in adolescent girls with obesity.

Methods: Participants (n=65, mean±SD 15.2±1.6y) were girls at-risk for T2D based on BMI ≥85%ile, ≥1 family member with T2D, and elevated depression (Center for Epidemiologic Studies Depression [CES-D] score ≥21). Trauma history (presence vs. absence) was assessed with the Schedule for Affective Disorders and Schizophrenia for School-Aged Children, and LOC eating (presence vs. absence) with the Eating Disorder Examination. T2D risk was assessed as HbA1c and Matsuda Whole Body Insulin Sensitivity Index (WBISI), derived from a 7-sample 2-hr OGTT. ANCOVA tested differences in HbA1c and WBISI by trauma and LOC, controlling for age, BMIz, race/ethnicity, and depression.

Results: Trauma history was endorsed in 40.6% and LOC eating in 36.4% of girls. Girls with and without a trauma history reported similar rates of LOC (36.4% vs. 37.5%, p=.93). Girls with trauma had higher HbA1c (5.7±0.06%) vs. those with no trauma (5.5±0.05%, p=0.04), with no difference in WBISI (p=0.32). Girls with LOC had worse WBISI vs. those with no LOC (3.0±0.53 vs. 4.8±0.40, p<0.01), with no difference in HbA1c (p=0.21).

Conclusions: Trauma history and LOC eating were unrelated to each other, but each related to different aspects of elevated T2D risk. Attention to both factors may warrant consideration in intervening to lessen T2D risk in teens with obesity and elevated depression.
