Disordered Eating Behaviors and Sexual Harassment in Italian Male and Female University Students

Examining an integrated sociocultural and objectification model of thinness- and muscularity-oriented disordered eating in Chinese older men and women

OBJECTIVE

We tested an integrated model of three prominent theories of disordered eating (tripartite influence theory, objectification theory, and social comparison theory) in a sample of older Chinese men and women.

METHOD

Chinese older men (n = 270) and women (n = 160) completed questionnaires assessing the tripartite influence, objectification, and social comparison theories and thinness- and muscularity-oriented disordered eating. Two structural equation models were tested in Chinese older men and women.

RESULTS

The integrated model showed good model fit and described meaningful variance in thinness- and muscularity-oriented disordered eating in Chinese older men and women. Higher appearance pressures were uniquely related to higher muscularity-oriented disordered eating in men. Across both gender groups, higher thinness internalization was uniquely related to higher thinness- and muscularity-oriented disordered eating, and in women only, higher muscularity internalization was uniquely related to lower thinness-oriented disordered eating. In men, higher upward and downward body image comparisons were uniquely related to higher and lower, respectively, muscularity-oriented disordered eating. In women, higher upward body image comparisons were only uniquely related to higher muscularity-oriented disordered eating while higher downward body image comparisons were uniquely related to both outcomes. Higher body shame was uniquely related to higher thinness-oriented disordered eating across both groups and in men alone, higher body shame was also uniquely related to higher muscularity-oriented disordered eating.

DISCUSSION

Findings, which tested the integration of tripartite influence, objectification, and social comparison theories, inform the prevention and treatment of disordered eating in Chinese older populations.

PUBLIC SIGNIFICANCE

The present study is the first to describe theories of disordered eating (tripartite influence, objectification, and social comparison) in Chinese older adults. Findings suggested good model fit and the integrated models described meaningful variance in thinness- and muscularity-oriented disordered eating in Chinese older women and men. Findings extend existing theories of disordered eating and, pending further study, may inform theory-driven prevention and treatment approaches in Chinese older adults.

A specific association between laxative misuse and suicidal behaviours in patients with anorexia nervosa and bulimia nervosa

OBJECTIVE

Eating disorders (ED) are associated with an in increased risk of suicidal behaviours. Laxative abuse might alter the gut-brain axis signaling, that might be implicated in the pathophysiology of suicide. This study aims to determine the association between laxative misuse and suicide attempt (SA) and suicidal ideation (SI) in patients with ED.

METHODS

277 patients with ED were recruited from an Eating Disorder Unit of Lapeyronie Academic Hospital, Montpellier, France. Sociodemographic and clinical data were collected. Chi-square and t test were used, with Bonferroni corrections where required. Multiple regression models assessed the relationships between laxative misuse, SA, and SI.

RESULTS

62 (22.4%) patients reported lifetime laxative misuse. They were more likely to have a history of SA than non-misusers [43.83 vs 19.9%, p < 0.001, odds ratio (OR) 3.68]. In the multivariate model, adjusted for other confounders, lifetime laxative misuse remained associated with SA (adjusted OR 3.79, p = 0.041). In past 28 days, patients with SA history reported misusing laxatives for more days than patients without SA history (6 vs 1.5 days, p = 0.01, adjusted for vomiting and ED severity). Laxative use days during past 28 days was associated with current SI, adjusted for vomiting in the same period (p = 0.017).

CONCLUSIONS

Current and lifetime laxative misuse were associated with SA history and current SI in patients with ED, at least in part independently of other suicide-related factors.

Stressful life events among individuals with a history of eating disorders: a case-control comparison

BACKGROUND

Experiencing stressful life events (SLEs) can negatively impact mental health and increase risk for psychiatric disorders including eating disorders (EDs). Previous research has shown that childhood sexual abuse is associated with some EDs, but less is known about the association between other non-sexual SLEs and EDs.

METHOD

A case-control study of individuals with (n = 495, age mean ± SD = 29.1 ± 9.8 years) and without (n = 395, age = 30.2 ± 11.7) self-reported lifetime history of EDs was conducted to compare history of self-reported SLEs. Participants reported history of sexual (e.g., rape, other sexual assault) and non-sexual (e.g., emotional abuse, assault, bereavement) life events using an adaptation of the Stressful Life Events Screening Questionnaire. Individuals with EDs were divided into ED subtypes along the restricting - binge eating/purging spectrum to examine subtype differences. Logistic regressions were conducted for each SLE and ED subtype to obtain odds ratios (ORs). We report p-values corrected for multiple comparisons.

RESULTS

Exposure to any SLE was significantly more common in individuals with EDs than in controls (OR = 2.47, p < .001). Specifically, rape, other sexual assault, and emotional abuse were significantly more common among individuals with a history of binge-eating/purging ED subtypes (ORs = 2.15-3.58, p's < .01) compared with controls. Furthermore, history of life-threatening disease and loss of a close relative/partner/friend were associated with some ED subtypes. The association between SLEs and EDs was stronger for individuals who had experienced multiple SLEs.

CONCLUSION

By investigating a range of different SLEs, we showed that both sexual and non-sexual SLEs were more common in individuals with a history of EDs (binge-eating/purging subtypes) than controls. Results highlight the importance of assessing a variety of past SLEs in risk assessment for different EDs.

Understanding the relationship between sexual harassment and eating disorder psychopathology: A systematic review and meta-analysis

OBJECTIVE

The experience of sexual harassment (SH) may exacerbate the drive toward an ideal and often unattainable physical appearance, creating the foundation of unhealthy eating, and greater shape and weight concerns. This systematic review aimed to synthesize evidence on the relationship between SH and eating disorder psychopathology, as well as mediating and moderating factors that contribute to this relationship.

METHOD

Six key databases were searched from inception to August 2020; including CINAHL, PsycInfo, PubMed, Medline, Scopus, and Web of Science.

RESULTS

Overall, 15 studies meeting inclusion criteria were found, with 14 reporting a statistically significant relationship between SH and eating disorder psychopathology. A meta-analysis with 12 cross-sectional studies confirmed a small but significant effect for this concurrent association. Moderators of this relationship included gender, posttraumatic stress, and anxiety. No studies in this review conducted true mediation.

DISCUSSION

Conclusions about causal and mediating relationship between SH and eating disorder psychopathology are constrained by the preponderance of cross-sectional design (14 of the 15 studies). Therefore, it is recommended that future studies focus on the use of longitudinal design, and also on adolescent populations, where first experiences of SH are usually reported, and which is also the peak age of onset for eating disorders.

The relationship between eating disorder psychopathology and sexuality: etiological factors and implications for treatment

PURPOSE OF REVIEW

There is a remarkable overlap between eating disorders and sexual problems, both in terms of sexual dysfunctions and risky sexual behaviors. This systematic review of the recent literature aimed at clarifying the nature of this relationship in terms of psychopathological meaning.

RECENT FINDINGS

Body image disturbance, and particularly body dissatisfaction and embodiment disorder, emerged as shared psychopathological dimensions between eating disorder symptoms and sexual dysfunctions. Interpersonal difficulties, a disturbed intimacy and insecure attachment style, but not a history of sexual abuse per se, resulted to play a pivotal role in the interconnection between eating disorder psychopathology and sexual dysfunctions. On the other hand, several studies confirmed the association between eating disorder symptoms and risky sexual behaviors, which has been explained in terms of several common psychopathological dimensions, including impulsivity and addiction.

SUMMARY

Sexuality is deeply interconnected with eating disorder psychopathology, and it should be considered a fundamental aspect in managing these disorders. An accurate assessment of sexual function might allow to characterize etiological information (e.g., sexual abuse) and maintaining factors (embodiment disorder and emotion dysregulation). Accordingly, the recovery of a good sexuality should be considered a crucial signal of recovery.

Mental distress and sexual harassment in Italian university students

Only a few studies have analyzed the association between sexual harassment (SH) and mental health controlling for other types of violence. The aim of this study was to describe SH among male and female university students and analyze the association between harassment and mental distress controlling for sexual violence. An observational survey was conducted at Trieste University (Italy). Students answered an anonymous questionnaire about harassment that included three domains-sexual harassment, gender harassment, cyber harassment-and three psychological health indicators. The global harassment index was computed, with three levels: 0, no harassment; level 1, harassment in at least one of the three domains; and level 2, harassment in two or three domains. The symptoms of mental distress were measured by the 12-item General Health Questionnaire (GHQ) for depressive symptoms; a question about panic symptoms; and a question about general health. The sample included 759 students (412 women; 18 to 29 years old). After adjustment for age, birth country, couple relationship, employment status, mother's education, and previous sexual violence, the risk of mental distress was increased with harassment exposure. Men were affected in perceived health and depressive symptoms (GHQ score ≥ 6); women were affected in panic symptoms. Harassment has a strong negative impact on the mental health of victims; in some cases, men may be more affected than women. Clinicians should be aware of the negative impact of SH also on men.

Sexual harassment and menstrual disorders among Italian university women: A cross-sectional observational study

AIMS

Menstrual disorders and sexual harassment are common among young women and interfere with their life and activities. We aimed to describe the association of sexual harassment and menstrual disorders among female university students.

METHODS

This cross-sectional, observational study examined the association between sexual harassment and menstrual disorders in a sample of 349 university students in Italy. Students answered an anonymous self-administered questionnaire. Descriptive bivariate analyses and logistic regression analyses were performed. Main outcome measures were associations between levels of exposure to sexual harassment (none, levels 1 and 2) and five menstrual disorders (premenstrual symptoms, heavy bleeding, pain, irregular cycles, and amenorrhea).

RESULTS

Among the women interviewed (mean age 20.4 ± 1.45 years), 146 (41.8%) had experienced sexual harassment in the previous 12 months: 91 (26.1%) level 1 and 55 (15.7%) level 2. The frequency of premenstrual symptoms was 31.9% ( n=110); heavy bleeding, 35.3% ( n=124); pain, 51.4% ( n=181); irregular cycles, 55.5% ( n=195); and amenorrhea, 6.7% ( n=23). After adjustment for age, place of birth, being in a couple relationship and receiving hormone therapy, the frequency of menstrual disorders, except for amenorrhea, was increased with sexual harassment, with a regular gradient from no harassment to level 2 harassment. Introducing factors of depression, specific gynaecological problems and lifetime sexual violence did not change the results. For instance, the adjusted odds ratios of premenstrual symptoms were 2.10 [1.19-3.68] for women with level 1 harassment and 3.58 [1.83-7.03] for women with level 2 compared with women without harassment exposure.

CONCLUSIONS

Sexual harassment is related to the prevalence of menstrual disorders. Healthcare providers should encourage dialogue with patients and address the issue of sexual violence or harassment.

Body dissatisfaction, excessive exercise, and weight change strategies used by first-year undergraduate students: comparing health and physical education and other education students

BACKGROUND

Health and Physical Education (HPE) teachers are known to be under social-, personal-, and employment-related pressure to be and appear physically fit, and to use dangerous dieting and weight control practices. This is problematic due to the influence this may have on their own health and the potential to model these attitudes and behaviours to their future students.

METHODS

In this paper, we compare the body image, dieting, disordered eating, and exercise behaviours of first year, HPE, and non-HPE, teacher education students. Participants were 596 first-year university student pre-service teachers (n = 249 HPE and n = 347 non-HPE) from three universities in Australia who completed self-report questionnaires. Analysis of covariance and logistic regression analyses were used to determine differences in attitudes and behaviours between these two groups for males and females separately.

RESULTS

We found that male HPE participants had significantly higher levels of drive for muscularity and obligatory exercise, and were more likely to be classified as having an exercise disorder, dieting, and using steroids than non-HPE students were. Female HPE students were more likely to engage in self-reported excessive exercise, to have higher scores on the Obligatory Exercise Questionnaire, and be classified as having an exercise disorder.

CONCLUSION

These findings are important as they confirm the presence of dieting and disordered eating attitudes and behaviours among all teacher education students, and highlight male HPE teachers as a potentially vulnerable group. These results may inform the implementation of intervention programs for teacher education students to ensure their personal wellbeing and professional capacity in promoting positive body image, nutrition, and physical activity among young people.
