Sexual violence, weight perception, and eating disorder indicators in college females

Sexual Assault Among College Women: The Role of Survivor Acknowledgment, Rape Myth Acceptance, Weight Bias, and Body Appreciation

Approximately one in five college women experience a sexual assault (SA), though a meaningful percentage of survivors do not acknowledge or label their experience as such. Research indicates that acknowledgment status is often influenced by how closely SA incidents align with the "real rape" script and degree of survivor rape myth acceptance (RMA). However, studies evaluating acknowledgment paired with other attitudes and health outcomes among survivors is sparse. The current study examined the relation between acknowledgment status, RMA, weight-related constructs, and psychological well-being among three groups of college women (N = 584): non-survivors, unacknowledged survivors, and acknowledged survivors. Findings indicate that, among survivors, acknowledged compared to unacknowledged SA is significantly associated with diminished body appreciation, self-esteem, and increased internalized weight bias, though no differences in psychological distress were found.

The role of sexual assault history and PTSD in responses to food intake among women with bulimic-spectrum eating disorders

Sexual abuse or assault (SA) history is associated with eating disorder severity and psychiatric comorbidity, including post-traumatic stress disorder (PTSD). Beyond persistent alterations in mood and cognitions characterizing PTSD, PTSD due to SA may contribute to greater increases in negative affect and body image concerns following food intake in bulimic syndromes (BN-S). To test this, participants (n = 172) with BN-S who reported PTSD due to SA, PTSD due to other forms of trauma, or neither completed clinical interviews and momentary reports of negative affect and shape/weight preoccupation before and after food intake. Participants with PTSD, regardless of trauma source, reported higher purging frequency whereas PTSD due to SA was associated with more frequent loss of control eating. For one task, changes in negative affect following food intake differed across the three groups. Negative affect decreased significantly in participants with PTSD without SA whereas nonsignificant increases were observed in those with PTSD with SA. Results of the present study suggest that source of trauma in PTSD may impact likelihood that eating regulates affect and provide insight into ways current treatments may be adapted to better target purging in BN-S comorbid with PTSD.

Factors Correlated With Sexual Assault Victimization Among College Students in the United States: A Meta-Analysis

Sexual assault (SA) continues to be a serious problem on college campuses in the United States. This meta-analysis sought to identify correlates for SA victimization on college campuses, as well as examine if there were any differences in correlates for men and women. Database searches utilizing Boolean search terms were used to identify studies to be included in the meta-analysis. Studies were included if they provided quantitative data on correlates for SA victimization among college students. A total of 118 studies yielding 405 unique effect sizes were included in this study. The strongest correlates for SA victimization among college students were physical intimate partner violence (IPV) perpetration, physical IPV victimization, emotional IPV victimization, and prior SA victimization. Other significant correlates were related to mental health (e.g., hopelessness, suicidal ideation, trauma symptoms, anxiety symptoms, depressive symptoms), and factors related to a campus party culture (e.g., binge drinking, alcohol use, drug use, Greek membership). We were able to compare seven correlates between men and women. Results of the meta-analysis also highlight the need for future research to examine additional correlates for SA victimization, as well as examine race/ethnicity and gender as separate categories when trying to further understand correlates for SA victimization.

The impact of trauma-related symptoms and neuroticism on compensatory behaviors in a sample of adults with eating disorders

INTRODUCTION

Inappropriate compensatory behaviors (ICBs), including purging, restricting, and excessive exercising, are key symptoms of several eating disorders (EDs). Studies have found positive associations between trauma and ICBs, although few studies have explored mechanisms that may explain these relationships. Emotion dysregulation has been posited as a mechanism that explains associations among ICBs and trauma. Given that individuals with high neuroticism may be particularly likely to use ICBs to regulate emotions following a trauma, the purpose of this study was to test whether neuroticism moderated the relationship between trauma-related symptoms and each type of ICB (purging, restricting, and excessive exercise).

METHOD

A community sample of adults with a DSM-5 ED (N = 263; 83.7 % female) completed measures of trauma-related symptoms, ED psychopathology, and personality.

RESULTS

Zero-inflated negative binomial models revealed that trauma-related symptoms alone predicted restricting and purging behavior. In addition, we found that neuroticism alone predicted the presence of excessive exercise. We found no significant interaction between trauma-symptoms and neuroticism.

CONCLUSION

Although past research has documented high rates of co-occurring ED and PTSD, the connections between trauma-related symptoms and ICBs are complex and may be unique to each type of ICB. Given that neuroticism may not influence the relationship between trauma-related symptoms and ICBs, more research should be done to establish an understanding of factors that could explain the relationship between ICBs and trauma-related symptoms. Novel interventions that simultaneously target restricting, purging, and trauma-related symptoms could be beneficial to explore.

What can my body do for me? Guided body-functionality mirror gazing task improved college women's body appreciation and body functionality orientation

Objective: Focusing on body functionality - what the body can do - may benefit women's body image. This pilot study examined the effects of focusing on body functionality appreciation during an audio-guided mirror gazing task (F-MGT). Participants: 101 college women, M(SD)_AGE = 19.49(1.31), were alternately assigned to F-MGT or a comparison with no guidance on how to examine the body, directed attention mirror gazing task (DA-MGT). Methods: Participants self-reported pre- and post-MGT body appreciation, state appearance satisfaction, and orientation to and satisfaction with physical functionality. Results: Group interactions were significant for body appreciation and functionality orientation. DA-MGT decreased body appreciation from pre- to post-MGT; F-MGT did not change. There were no significant interactions in post-MGT state appearance satisfaction or functionality satisfaction, though state appearance satisfaction increased significantly in F-MGT. Conclusions: Integrating body functionality may buffer against harmful effects of mirror gazing. Given F-MGT's brevity, additional work must assess its potential as an intervention technique.

Past-Year Abuse and Eating Disorder Symptoms Among U.S. College Students

Evidence consistently indicates associations between eating disorders (EDs) and childhood emotional, physical, and sexual abuse, but the relationship between EDs and abuse occurring later in development has largely been unexplored. Therefore, the objective of this study was to examine associations between past-year abuse and ED symptoms among college students. Participants represented 12 U.S. colleges and universities participating in the Healthy Bodies Study (HBS) between 2013 and 2015 (N = 10,204; M_age = 23.38 years). Students self-reported experiences of emotional, physical, and sexual abuse over the past year. Cognitive ED symptoms (i.e., dietary restraint, shape/weight overvaluation, body dissatisfaction) were measured via the Short-Eating Disorder Examination-Questionnaire (S-EDE-Q), and behavioral ED symptoms (i.e., binge eating, purging) were measured via items from the full EDE-Q. Regression models that adjusted for demographics and weight status were conducted to examine associations between past-year abuse and ED symptoms. Past-year emotional, physical, and sexual abuse each exhibited independent associations with ED symptoms. When mutually adjusting for emotional, physical, and sexual abuse, past-year emotional abuse was associated with higher levels of dietary restraint (b = 0.20, p = .02), shape/weight overvaluation (b = 0.85, p < .001), body dissatisfaction (b = 0.63, p < .001), binge eating (prevalence ratio [PR] = 1.23, p = .002), and purging (PR = 1.68, p < .001), and past-year sexual abuse was associated with shape/weight overvaluation (b = 0.35, p = .03) and purging (PR = 1.71, p = .009) but no other ED symptoms. No associations were observed for past-year physical abuse in mutually adjusted models. In summary, past-year emotional abuse emerged as a key correlate of all ED symptoms examined in this sample of U.S. college students, while past-year sexual abuse also emerged as a key correlate of shape/weight overvaluation and purging. Findings emphasize the need to screen for abuse and implement abuse prevention efforts on college campuses.

Disordered eating as a repercussion of sexual assault: a consequence to consider

PURPOSE

This study aims at clarifying the links between sexual violence and disordered eating (DE).

METHODS

In a sample of 12,638 victims of self-reported sexual violence, we analyzed the situation of 546 victims that declared having developed DE. We assessed the characteristics of the assault (age, type of aggression) and the medical consequences (PTSD, depression, suicide attempts, anxiety disorders, etc.).

RESULTS

DE prevalence was 4.3% in the victim sample. The age of the first assault in DE victims was significantly lower than that of the whole population (12 years vs 16 years for median; p < 0.001). A much higher prevalence of sexual assault consequences was present in victims developing DE with odd ratios (OR) for: self-mutilation (OR = 11.5 [8.29-15.95], p < 0.001); depression (OR = 5.7 [4.81-6.86], p < 0.001); self-medication (OR = 5.3 [3.86-7.19], p < 0.001); suicide attempts (OR = 4.5 [3.59-5.67], p < 0.001); post-traumatic stress disorder (OR = 3.8 [2.99-4.78], p < 0.001); anxiety troubles (OR = 5.2 [4.11-6.47], p < 0.001); alcoholism (OR = 4.0 [2.81-5.58], p < 0.001).

CONCLUSION

This study confirms the link between DE and sexual violence, especially in childhood, leading to severe psychological consequences. In this context, DE should be envisaged as a coping strategy accompanying emotional dysregulation due to traumatic events, and be treated as such.

LEVEL OF EVIDENCE

Level IV: Evidence obtained from multiple time series analysis such as case studies.

Sexual Victimization and Mental Health in Female University Students

Although sexual assaults on female university students are a public health concern, studies that have examined this issue have not used behaviorally specific definitions of the various types of sexual victimization. Furthermore, hardly any data exists on female Spanish university students. The objectives of this study were to analyze the prevalence of different forms of sexual assault against female Spanish university students, determine the risk factors associated with sexual assault, analyze the association between sexual victimization and mental health problems, and determine the differential risk of more serious types of sexual assault. A cross-sectional study was conducted among a random sample of 871 students from the University of Santiago de Compostela (Spain) (mean age 20.7 years, SD = 2.8). The current study assessed various types of sexual violence (i.e., unwanted sexual contact, attempted coercion, coercion, attempted rape, rape), as well as rates of depression, anxiety, stress, eating disorders, substance abuse, suicide risk, and suicide attempts. Of the female students surveyed, 28.5% had suffered some form of sexual violence during the previous year, 22.3% reported unwanted sexual contact, 8.8% attempted coercion, 6.5% coercion, 10.4% attempted rape, and 7.9% had been raped. Lower risk was associated with having a partner and being heterosexual. Being 18 years of age and prior experiences of sexual victimization were associated with higher risk. Being the victim of attempted coercion was associated with a higher risk of depression, while victims of attempted rape were at higher risk for substance use. Rape victims were at the highest risk for all mental health conditions studied, with the exception of suicide attempts. Due to the high rates at which Spanish female university students experience sexual violence, planning and resources are needed to address their mental health needs, especially those who are victims of rape.

Sex and racial/ethnic differences in the prevalence of overweight and obesity among U.S. college students, 2011-2015

To investigate sex and racial/ethnic differences in overweight and obesity in college students. Participants: A nationally representative sample of 319,342 U.S. college students (mean age = 20.4 years; 67.7% female) from Fall 2011 to Spring 2015. Methods: A secondary data analysis of multi-year cross-sectional data was performed. Multiple logistic regression was used to examine factors (e.g. cumulative grade average, year in school, and living place) associated with overweight and obesity determined from BMI calculated by self-reported height and weight. Results: The prevalence of overweight and obesity was significantly higher for both sexes in Spring 2015 than in Fall 2011. Significant differences were found in overweight and obesity by sex and race/ethnicity. Higher adjusted odds ratios for overweight and obesity were observed for men, blacks, and Hispanics (compared to whites). Asians had the lowest adjusted odds of overweight and obesity. Conclusions: Intervention strategies for the prevention and management of overweight and obesity in U.S. college students should consider sex and racial/ethnic inequalities.

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

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.

Racial/ethnic differences in body weight perception among U.S. college students

OBJECTIVE

To examine racial/ethnic differences in weight perception by sex among U.S. college students.

PARTICIPANTS

a national sample (N = 70,267) of college students selected from 2- and 4-year postsecondary institutions (N = 62) during the Fall semester from 2011 to 2014.

METHODS

This is a secondary data analysis using 4 years of American College Health Association-National College Health Assessment IIb data. Sex-stratified multinomial logistic regression was performed to investigate racial/ethnic differences in body weight perception.

RESULTS

Compared with non-Hispanic whites, non-Hispanic black men and women were more likely to underestimate their body weight (p < .01). Asian men and women were more likely to overestimate their body weight than non-Hispanic whites (p < .001).

CONCLUSIONS

Weight-related interventions should take into account racial/ethnic differences in body weight perception.

Update on Psychological Trauma, Other Severe Adverse Experiences and Eating Disorders: State of the Research and Future Research Directions

PURPOSE OF REVIEW

This paper provides an updated review of the literature on the relationship between psychological trauma exposure, other severe adverse experiences, and eating disorders.

RECENT FINDINGS

Trauma exposure and other severe adverse experiences (e.g., emotional abuse) in both childhood and adulthood are associated with eating disorders. The relationship between traumatic and other adverse experiences and eating disorders appears to be mediated by emotional and behavioral dysregulation, as well as by cognitive factors such as self-criticism. Biological vulnerabilities may also be relevant to this relationship. Overall, the literature is limited by predominantly cross-sectional designs. There is clear evidence of a correlational relationship between trauma exposure and other severe adverse events, and eating disorders. Both risk and maintenance factor hypotheses have been put forth; however, prospective research testing these hypotheses remains limited. Future research should use prospective designs and focus on trauma-related symptoms (rather than trauma exposure) in order to advance research on risk and maintaining factors for eating disorders and inform treatment directions.
