Traumatic Life Events, Violence, and Obesity: A Cross-Sectional Study from 408 Patients Enrolled in a Bariatric...

Obesity is a chronic disease that increases cardiovascular and metabolic morbidity and mortality, decreases quality of life, and increases health care costs. While the role of lifestyle behavioral factors in the development of obesity is well established, the role of traumatic life events, including violence, is unclear. The purpose of this study was to describe situations of traumatic life events reported by patients undergoing a bariatric surgery program, with a particular focus on sexual violence and its clinical correlates.

In this cross-sectional study, patients with grade II or III obesity, admitted to our digestive surgery department for bariatric surgery from August 01, 2019, to December 31, 2020, underwent a structured interview by a trained psychologist to describe the history of traumatic life events self-reported by the patients. The primary endpoint was the presence of a history of sexual violence (SV). Multivariate logistic regressions were applied to identify independent risk factors for SV.

Of the 408 patients interviewed, 87.1% reported at least one traumatic life event and 33.1% reported having had an SV in the past. Female gender (aOR = 7.44, 95% confidence interval: 3.85-15.73; p < 0.001) and higher body mass index (1.05, 1.02-1.08; p = 0.002) were associated with an increased risk of SV. Male gender was associated with a higher risk of difficulties including sports cessation, depression, and work-related distress.

In the context of obesity, psychosocial trauma is characterized by a high frequency and several gender specificities that must be taken into account in the management of these patients.
