Objective: This study tested the association between food insecurity and eating disorder (ED) pathology, including probable ED diagnosis, among two cohorts of university students before and during the beginning of the COVID-19 pandemic.

Method: Students (n = 579) from a large Midwestern American university completed self-report questionnaires assessing frequency of ED behaviors, ED-related impairment, and individual food insecurity as measured by the Eating Disorder Diagnostic Scale 5, Clinical Impairment Assessment, and Radimer/Cornell, respectively. Chi-square tests and MANOVA with post-hoc corrections were conducted to compare demographic characteristics, ED pathology, and probable ED diagnosis prevalence between students with and without individual food insecurity.

Results: Partially supporting hypotheses, MANOVA indicated significantly greater frequency of objective binge eating, compensatory fasting, and ED-related impairment for students with food insecurity compared with individuals without food insecurity. Chi-squared tests showed higher prevalence of ED diagnoses among individuals with food insecurity compared with those without food security (47.6 vs. 31.1%, respectively, p < .01, NNT = 6.06), specifically bulimia nervosa and other specified feeding and eating disorder. There were no differences in food insecurity before or during the beginning of the COVID-19 pandemic.

Discussion: Consistent with prior literature, food insecurity was associated with elevated ED psychopathology in this sample. Findings emphasize the importance of proper ED screening for college students vulnerable to food insecurity and EDs.

Impact of trauma in childhood and adulthood on eating-disorder symptoms.

Eat Behav 2020 12 27;39:101426. Epub 2020 Aug 27.

Exposure to a traumatic event is concurrently and prospectively associated with disordered-eating behaviors such as binge eating, restricting, and purging. Specifically, purging has been found to be elevated in individuals with trauma histories, suggesting that purging may be a method for coping with trauma-related distress. However, there has been limited research investigating whether the time at which trauma occurs during development is differentially associated with disordered-eating behaviors and internalizing psychopathology. The purpose of this study was to examine the effect of trauma that occurred in childhood, adulthood, or childhood and adulthood on eating disorder (ED) and internalizing psychopathology. Participants were community-recruited adults with a current DSM-5 ED (N = 225) and were subsequently grouped into categories based on the time at which trauma occurred. Groups included: no trauma exposure ED controls (n = 54), child trauma group (n = 53), adult trauma group (n = 53), and child+adult trauma group (n = 65). We compared groups on their level of disordered-eating symptoms. Participants were administered the Structured Clinical Interview for DSM-IV, the Eating Pathology Symptoms Inventory (EPSI), and the Inventory of Depression and Anxiety Symptoms-II (IDAS-II). Univariate analyses revealed significantly higher levels of purging symptomatology in the child+adult trauma group compared to the no trauma, child trauma, and adult trauma groups. The current study highlights the importance of assessing the timing of trauma among individuals with EDs. In particular, our study indicates a need for further investigation to explain why individuals with ED and trauma histories engage in greater purging.
