Diagnosis of Eating Disorders Among College Students: A Comparison of Military and Civilian Students

Prevalence and correlates of disordered eating at a large state university before and after the onset of the COVID-19 pandemic

BACKGROUND

Emerging adulthood is a transitory period in which disordered eating (DE) manifests; collecting data on the prevalence of DE among this population as well as demographic and behavioral correlates are important public health goals.

METHODS

Data from an annual survey of undergraduate students at a large state university from 2019 to 2022 were analyzed, allowing researchers to compare prevalence and correlates before and after the onset of the COVID-19 pandemic using two brief screeners: the SCOFF and Eating Disorder Screener for Primary Care (ESP). We hypothesized that rates of DE would be greater after the onset of COVID-19 as compared to before. We also hypothesized that those identifying as women, reporting higher alcohol or drug use, and contemplating suicide would have greater odds of reporting symptoms consistent with DE.

RESULTS

DE was significantly lower in pre-pandemic years compared to pandemic years: ESP pre = 38.01%(n = 704), pandemic = 48.79%(n = 645), p < 0.001; SCOFF pre = 22.82%(n = 422), pandemic = 31.46%(n = 414), p < 0.001. Logistic regressions showed women and students who contemplated suicide reported significantly greater DE, regardless of screener or time period. Inconsistent relationships were found between DE and current substance use.

CONCLUSION

These findings may inform targeted interventions for those most vulnerable to disordered eating.

Anorexia and Bulimia Nervosa in Spanish Middle-Aged Adults: Links to Sociodemographic Factors, Diet, and Lifestyle

AIM

This study examines the prevalence of eating disorders, particularly anorexia and bulimia nervosa, among middle-aged Spaniards, noting their rising incidence in men as well as women. It explores how these disorders relate to sociodemographic factors and lifestyle habits.

METHODS

A cross-sectional survey was conducted from August 2020 to November 2021 via online platforms. Participants were Spanish nationals aged 31-50 years residing in Spain.

RESULTS

Out of 9913 respondents, 96.66% reported no diagnosed eating disorders, while 3.34% reported one or more (0.36% anorexia nervosa; 0.53% bulimia nervosa; 1.97% other eating disorders; 0.48% multiple disorders). Concerns about body image and lack of control over food intake were reported by 50% and 28%, respectively, suggesting potential undiagnosed disorders. Significant BMI differences were noted between healthy individuals and those with anorexia or bulimia.

CONCLUSIONS

Anorexia and bulimia affect both adolescents and middle-aged individuals, challenging existing stereotypes. The high prevalence of undiagnosed eating disorder behaviors highlights the need for early detection. To address these issues in Spain, targeted awareness programs are essential to reduce stigma and improve service access through clinical, social, and political collaboration.

Incidence and prevalence of eating disorders among U.S. military service members, 2016-2021

OBJECTIVE

Despite unique experiences that may increase eating disorder risk, U.S. military service members are an understudied population. The current study examined incidence and prevalence of eating disorder diagnoses in U.S. military personnel.

METHOD

This retrospective cohort study utilized Military Health System Data Repository (MDR) data on eating disorder diagnoses (2016-2021). Active duty, Reserve, and National Guard U.S. military service members who received care via TRICARE Prime insurance were identified by ICD-10 eating disorder diagnostic codes.

RESULTS

During the 6-year surveillance period, 5189 Service members received incident eating disorders diagnoses, with a crude overall incidence rate of 6.2 cases per 10,000 person-years. The most common diagnosis was other/unspecified specified eating disorders, followed by binge-eating disorder, bulimia nervosa, and anorexia nervosa. There was an 18.5% overall rise in total incident cases across the surveillance period, but this trend was not statistically significant (p = 0.09). Point prevalence significantly increased across the 6-year timeframe for total eating disorders (p < 0.001). Period prevalence for 6-year surveillance period was 0.244% for total eating disorders, 0.149% for other/unspecified eating disorder, 0.043% for bulimia nervosa, 0.038% for binge-eating disorder, and 0.013% for anorexia nervosa.

DISCUSSION

Overall crude incidence estimates for total eating disorders were higher than reported in prior research that included only active duty Service members and required an eating disorder diagnosis code in the first or second diagnostic position of the medical record. Comprehensive and confidential studies are needed to more thoroughly characterize the nature and scope of eating disorder symptomatology within U.S. military personnel.

PUBLIC SIGNIFICANCE

U.S. military service members are a vulnerable population with regard to eating disorder symptoms. Previously reported incidence and prevalence estimates using data from the Military Health System may have been underestimated due to overly stringent case definitions. Given personal and occupational barriers (e.g., career consequences), confidential studies of military personnel may provide more complete data on the scope of eating disorders to inform screening and clinical practice guidelines for military populations.

Who gets treated for an eating disorder? Implications for inference based on clinical populations

BACKGROUND

The minority of people with an eating disorder receive treatment. Little is known about predictors of receiving treatment.

METHODS

Using data from the Growing Up Today Study we identified correlates of receiving treatment for an eating disorder among the 1237 U.S. women who answered questions on treatment history in 2013 and reported meeting criteria for subthreshold eating disorder in ≥ 1 year between 1996 and 2013. Logistic regression models using generalized estimating equations were used to estimate the relative odds of receiving treatment.

RESULTS

Approximately 11% of the women reported receiving treatment for an eating disorder. Independent of type of eating disorder, those who had received a diagnosis of depression or anxiety were more likely (odds ratio (OR) = 3.05 95% confidence interval (CI) 1.87-4.97) to receive treatment for an eating disorder. Women with obesity were approximately 85% less likely to receive treatment (OR = 0.13, 95% CI 0.04-0.46) regardless of their type of eating disorder or history of depression of anxiety diagnosis.

CONCLUSIONS

Most women meeting criteria for an eating disorder do not receive treatment. Women with BED or obesity are the least likely to receive treatment.

The use and misuse of the SCOFF screening measure over two decades: a systematic literature review

PURPOSE

The SCOFF questionnaire was designed as a simple, memorable screening tool to raise suspicion that a person might have an eating disorder. It is over 20 years since the creation of the SCOFF, during which time it has been widely used. Considering this, we wish to review the use of the SCOFF in peer-reviewed scientific journals, and to assess whether it is being used appropriately in the manner in which it was originally devised and tested.

METHODS

The Preferred Reporting Items for a Systematic Review and Meta-analysis (PRISMA) guidelines were followed, and all search strategies and methods were determined before the onset of the study. PubMed and Wiley Online Library were searched using the terms SCOFF and eating. Two reviewers were involved in the reviewing process. Criteria for appropriate use of the SCOFF were formalised with the tool's original authors.

RESULTS

180 articles were included in the final review. 48 articles had used the SCOFF appropriately, 117 articles inappropriately and 15 articles had been mixed in the appropriateness of their use.

CONCLUSION

This systematic review highlights the inappropriate use of the SCOFF in diverse languages and settings. When used correctly the SCOFF has made a significant contribution to the understanding of eating disorders and its simplicity has been applauded and led to widespread use. However in over two-thirds of studies, the use of the SCOFF was inappropriate and the paper highlights how and in what way it was misused, Guidelines for the appropriate use of the SCOFF are stated. Future validation and avenues of research are suggested.

Naturalistic symptom trajectories of atypical anorexia nervosa, anorexia nervosa, and bulimia nervosa in a prospective cohort study of United States college students

OBJECTIVE

Research on the natural course of symptoms of atypical anorexia nervosa (AN) relative to AN and bulimia nervosa (BN) is limited yet needed to inform nosology and improve understanding of atypical AN. This study aimed to 1) characterize trajectories of eating disorder and internalizing (anxiety, depression) symptoms in college students with and without a history of atypical AN, AN, and BN; and 2) compare sex and race/ethnicity distributions across groups.

METHOD

United States college students who participated in Spit for Science™, a prospective cohort study, were classified as having a history of atypical AN (n = 125), AN (n = 160), BN (n = 617), or as non-eating-disorder controls (NCs, n = 5876). Generalized and linear mixed-effects models assessed group differences in eating and internalizing symptom trajectories, and logistic regression compared groups on sex and race/ethnicity distributions.

RESULTS

Atypical AN participants demonstrated elevated eating disorder and internalizing symptoms compared to NCs during college, but less severe symptoms than AN and BN participants. Although all eating disorder groups showed signs of improvement in fasting and driven exercise, purging and depression remained elevated. Atypical AN participants showed increasing anxiety and stable binge-eating trajectories compared to AN and/or BN participants. The atypical AN group comprised significantly more people of color than the AN group.

DISCUSSION

Findings underscore that atypical AN is a severe psychiatric disorder. As atypical AN may present as less severe than AN and BN and disproportionately affects people of color, clinicians should be mindful of biases that could delay diagnosis and care.

PUBLIC SIGNIFICANCE

College students with histories of atypical AN, AN, and BN demonstrated improvements in fasting and driven exercise and stable purging and depression levels. Atypical AN students showed worsening anxiety and stable binge-eating trajectories compared to favorable changes among AN and BN students. A higher percentage of atypical AN (vs. AN) students were people of color. Findings may improve the detection of atypical AN in college students.

Intersectionality of demographic characteristics in self-reported anorexia nervosa, bulimia nervosa, and probable eating disorders among college students

OBJECTIVE

To investigate associations between identity intersectionality, with a primary focus on minority identity, and probable eating disorders (EDs) within the US college student population.

METHOD

Data consisting of n = 414,299 college students' responses to the American College Health Association's National College Health Assessment between fall 2015 and spring 2019 were utilized for this study. Overall and stratified adjusted odds ratios (aORs) were used to assess the association between different facets of identity (i.e., race/ethnicity, gender identity, and sexual orientation) and probable EDs.

RESULTS

Among all, in our analytic sample, 7.15% reported a probable ED. Interactions between all three identity variables were significant, and thus stratified odds ratios were evaluated. Transgender men were significantly more likely to report probable ED than cisgender male peers within the following racial/ethnic groups: non-Hispanic White (aOR: 3.33; 95% CI: 2.79, 3.96; p < .0001), non-Hispanic Black (aOR: 3.29; 95% CI: 1.72, 6.28; p = .0003), Hispanic (aOR: 2.31; 95% CI: 1.55, 3.43; p < .0001), Asian or Pacific Islander (aOR: 2.19; 95% CI: 1.45, 3.30; p = .0002), Biracial or Multicultural (aOR: 3.36; 95% CI: 2.17, 5.22; p < .0001), and other (aOR: 4.19; 95% CI: 2.25, 7.79; p < .0001).

CONCLUSIONS

This study underscores the importance of increasing our understanding of interactions between marginalized identities and the ways in which minority identity informs ED risk.

PUBLIC SIGNIFICANCE

The impact of multiple marginalized identities on ED outcomes is not well understood. Our study expands on previous ACHA-NCHA studies by addressing identity intersectionality, looking at more than one identity at a time (i.e., specifically race/ethnicity, gender identity, and sexual orientation). Our results contribute unique risk profiles for students who identify with multiple marginalized groups. Further, they indicate that that these associations vary based on the compounded effect of the demographic factors considered.

Sleep reactivity is associated with social anxiety and disordered-eating behaviors in college students

Objective: Investigate whether sleep reactivity was associated with social anxiety and disordered-eating behaviors in a college population. Participants: One hundred ninety-eight college-age men and women. Methods: Participants completed self-report measures of social anxiety, disordered-eating behaviors and sleep reactivity. Results: Sleep reactivity was associated with greater dietary restriction and purging, controlling for social anxiety but it was not associated with binge eating. Sleep reactivity was associated with elevated symptoms of social anxiety, controlling for disordered-eating behaviors. Conclusions: The results suggest that sleep reactivity represents a shared correlate of disordered-eating behaviors and social anxiety that may partially explain their co-occurrence. Interventions to help college students high in sleep reactivity effectively manage stress and regulate their sleep may aid in the prevention and treatment of social anxiety and disordered-eating behaviors.

Iatrogenic triggers for anorexia nervosa and bulimia nervosa: A WHO safety database disproportionality analysis

Eating disorders, characterized by abnormal eating, weight control behaviors or both include anorexia nervosa (AN) and bulimia nervosa (BN). We investigated their potential iatrogenic triggers, using real-world data from the WHO safety database (VigiBase®). VigiBase® was queried for all AN and BN reports. The reports were classified as `pediatric' or `adult' according to age. Disproportionality analyses relied on the Information Component (IC), in which a 95% confidence interval lower-end positivity was required to suspect a signal. Our queries yielded 309 AN and 499 BN reports. Isotretinoin was disproportionately reported in pediatric AN (IC 3.6; [2.6-4.3]), adult AN (IC 3.1; [1.7-4.0]), and pediatric BN (IC 3.9; [3.0-4.7]). Lamivudine (IC 4.2; [3.2-4.9]), nevirapine (IC 3.7; [2.6-4.6]), and zidovudine (IC 3.4; [2.0-4.3]) had the highest ICs in adult AN. AN was associated with isotretinoin, anticonvulsants in minors, and antiretroviral drugs in adults. In adults, BN was related to psychotropic and hormonally active drugs. Before treatment initiation, an anamnesis should seek out mental health conditions, allowing the identification of patients at risk of developing or relapsing into AN or BN. In addition to misuse, the hypothesis of iatrogenic triggers for AN and BN should also be considered.

The prevalence and risk factors of screen-based disordered eating among university students: a global systematic review, meta-analysis, and meta-regression

PURPOSE

The purpose of this review was to estimate the prevalence of screen-based disordered eating (SBDE) and several potential risk factors in university undergraduate students around the world.

METHODS

An electronic search of nine data bases was conducted from the inception of the databases until 1st October 2021. Disordered eating was defined as the percentage of students scoring at or above established cut-offs on validated screening measures. Global data were also analyzed by country, research measure, and culture. Other confounders in this review were age, BMI, and sex.

RESULTS

Using random-effects meta-analysis, the mean estimate of the distribution of effects for the prevalence of SBDE among university students (K = 105, N = 145,629) was [95% CI] = 19.7% [17.9%; 21.6%], I2 = 98.2%, Cochran's Q p value = 0.001. Bayesian meta-analysis produced an estimate of 0.24, 95% credible intervals [0.20, 0.30], τ = 92%. Whether the country in which the students were studying was Western or non-Western did not moderate these effects, but as either the mean BMI of the sample or the percentage of the sample that was female increased, the prevalence of SBDE increased.

CONCLUSIONS

These findings support previous studies indicating that many undergraduate students are struggling with disordered eating or a diagnosable eating disorder, but are neither receiver effective prevention nor accessing accurate diagnosis and available treatment. It is particularly important to develop ever more valid ways of identifying students with high levels of disordered eating and offering them original or culturally appropriate and effective prevention or early treatment.

Prevalence, correlates, and gender disparities related to eating disordered behaviors among health science students and healthcare practitioners in Lebanon: Findings of a national cross sectional study

Background

The raised prevalence of eating disorders (ED) amongst health science students and health professionals is of mounting concern. This study aims to determine the prevalence and correlates of eating disorders risk amongst a sample of Lebanese health science students and healthcare practitioners of both genders.

Methods

This cross-sectional study enrolled a convenient sample of 1,000 participants (mean age: 23 ± 5.4; females: 74.9%) from faculties of health sciences, clinics, pharmacies, and hospitals. The validated Eating Attitudes Test (EAT-26) was used to screen for eating disorders. Anthropometric data were self-reported by respondents to assess their nutritional status.

Results

The risk of eating disorders was prevalent in 22.5% of participants. Females were at higher risk of ED compared to males p = 0.03. Eating disorders risk did not differ between students and practitioners (p = 0.3). The highest proportion of high-risk participants were students studying nutrition and practitioners (40.9%), outracing their counterparts in nursing (18.7%), medicine (17.8%), pharmacy (17.7%), and midwifery (4.9%) sciences (p = 0.02). Most high-risk participants had normal body weight (60.4%), and 28.9% were overweight (p = 0.001). Female gender, nutrition profession, and dieting were associated with increasing the odd of ED. Particularly, dieting increased the risk around five times. Further, each 3 participants over 10 were facing binge eating behavior.

Conclusion

This study uncovers an undervalued profession-related-health-disorder in Lebanese health science students and healthcare practitioners. Specific attention should be given to EDs in professional educational programmes across healthcare disciplines.
