Childhood traumatic experiences in people with obesity with and without eating disorders who are seeking bariatric surgery: the role of attachment relationships and family functioning

PurposeThe present study examines the impact of traumatic childhood experiences in people with obesity seeking bariatric surgery. It considers the presence of eating disorders (ED) in the population with obesity and tests the role of attachment and family relationships as mediators of the relationship between traumatic events and ED.Method110 participants with severe obesity and 98 participants of a healthy weight (control group) filled out The Childhood Trauma Questionnaire (CTQ-SF), the Attachment Style Questionnaire (ASQ) and the Family Adaptability and Cohesion Evaluation Scale (FACES IV).ResultsComparing the two groups on psychological variables, higher scores in the CTQ Emotional neglect and ASQ insecure attachment scales emerged in the control group than the group with obesity. Considering the presence/absence of an ED only in the group with obesity, and comparing these subgroups, higher scores in traumatic experiences emerged in the individuals with obesity and with ED than the individuals with obesity without ED. Moreover, participants with ED scored higher in ASQ insecure attachment and had lower levels of flexibility in family functioning than the group without ED. Finally, Logistic Regression models showed that insecure anxious attachment and dysfunctional familial relationships affected the relationship between traumatic childhood experiences and the presence of ED in the group with obesity.ConclusionThese findings suggest the importance focusing on psychosocial factors linked to obesity, specifically on attachment styles and familial relationships as emotion regulation strategies, since the impact of traumatic childhood events on psychopathology could be ameliorated by an individual's ability to rely on a significant attachment figure.Level of evidenceLevel II, evidence obtained from well-designed controlled trials without randomization.
