The Relationship between Binge Eating Disorder and Suicidality: A Systematic Review

Suicidal thoughts and attempts in a transdiagnostic eating disorder sample: Do diagnostic severity criteria predict risk?

OBJECTIVE

Eating disorders (EDs) are associated with elevated suicide. Low body mass index (BMI) and frequency of purging and binge eating represent severity criteria for EDs and distinguish full-threshold EDs from other specified feeding and eating disorders (OSFED). However, no work has taken a transdiagnostic approach to studying whether severity of these or other features is associated with suicidal ideation (SI) and attempts.

METHOD

We examined diagnostic status, ED features, and SI and attempts in a large, transdiagnostic, community sample of 257 women with EDs and 45 controls without a current or past ED in the United States using the EDs Examination interview and the Structured Clinical Interview for the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders).

RESULTS

SI and suicide attempts (SA) were elevated in OSFED compared to controls but did not differ between OSFED and full-threshold EDs. Higher BMI predicted increased SI. Number of purging methods, but not frequency, was related to history of SA. Binge episode frequency and size were not significant predictors.

CONCLUSIONS

OSFED presents with elevated SI and SA, and ED severity criteria that distinguish OSFED from full-threshold EDs do not predict SI or SA. Suicide risk assessments should be implemented universally across EDs in clinical practice.

What medical providers need to elevate outpatient care for adolescents and young adults with binge-eating disorder: A novel protocol

PURPOSE

Binge-eating disorder (BED) in adolescents and young adults is underrecognized and understudied and no standardized guidelines exist for medical providers caring for this population. To highlight the lack of extant evidence, we examine the demographic characteristics of youth with BED in an academic eating disorders (EDs) program and primary care clinic and describe the needs of their medical care providers.

METHOD

A retrospective chart review was conducted for patients who met criteria for BED from July 2021 to June 2022. We surveyed their medical providers to understand their needs in caring for this population. A multidisciplinary team with expertise in the care of youth with EDs amalgamated current evidence in caring for youth with BED into a protocolized care schema designed for implementation in the outpatient medical setting.

RESULTS

Eighteen youth with BED were reviewed, 14 identified as female, 3 as male, and 1 as "Other." Average age was 15.4 (2.7) years old, and mean body mass index was 35.90 (8.25). 33.3% (6) patients identified as White/Caucasian, followed by 22.2% (4) Hispanic/Latinx. Eleven of 18 were privately insured. The most common medical recommendations were for regular meals and snacks and for individual psychotherapy. Medical providers desired more education about identification and management of youth with BED.

CONCLUSIONS

To address the lack of medical care guidelines for youth with BED, recommendations in this Forum include: increased education for medical providers, standardized medical monitoring, an emphasis on psychotherapy, and a weight-inclusive orientation.

PUBLIC SIGNIFICANCE

Adolescents and young adults with BED are underrecognized and undertreated. Little is known about the characteristics of these patients and the medical care these patients receive within academic EDs program. For the first time, preliminary recommendations for medical care are provided.

Risk and protective factors for self-harm in adolescents and young adults: An umbrella review of systematic reviews

We conducted an umbrella review to synthesise the evidence from systematic reviews and meta-analyses that examined the risk and protective factors for self-harm in young people. We searched six different databases and used the AMSTAR-2 checklist for quality assessment. The importance of each risk and protective factor was determined based on (1) the number of times it was identified by general reviews examining any risk or protective factor, and (2) the effect sizes from meta-analyses. There were 61 systematic reviews included in this review. The most frequently identified risk factors for self-harm in young people included childhood abuse, depression/anxiety, bullying, trauma, psychiatric illnesses, substance use/abuse, parental divorce, poor family relationships, lack of friends, and exposure to self-harm behaviour in others. The risk factors with the strongest evidence for an association with self-harm were behavioural disorders, personality disorders and depression or anxiety. There was a dearth of systematic reviews examining protective factors but good family/friend relationships were most frequently identified. There was also evidence to show that non-suicidal and suicidal self-harm shared many of the same risk factors. Clinicians and other professionals who work with young people should be particularly cognisant of the psychiatric and adverse life event risk factors as well as the substance use, education-related and individual-level (e.g. being LGB) risk factors for self-harm. Knowledge of risk factors for self-harm can potentially be used to inform the design and implementation of prevention measures and further research is needed on the protective factors for self-harm.

Prevalence and predictors of binge eating disorder symptoms among a sample of university students in Bangladesh: A cross-sectional survey

Background and Aims

There is a dearth of information about binge eating disorder (BED) among Bangladeshi university students, who may be more susceptible to BED due to the rise in unhealthy lifestyles and food habits. Therefore, the purpose of this study was to assess the prevalence and associated factors of BED symptoms among Bangladeshi university students.

Methods

Students (N = 525) from three public universities in Bangladesh participated in this cross-sectional study between November 2022 and March 2023. Face-to-face interviews were conducted using a structured paper-based questionnaire that included two validated survey tools; the binge eating disorder screener and the patient health questionnaire-9. To identify the factors associated with BED symptoms, multiple logistic regression analysis was conducted, with sociodemographic and behavioral information (e.g., age, sex, smoking status, etc.) considered as covariates.

Results

The prevalence of BED symptoms among participants (mean age 21.28 years, 50.3% male and 49.7% female) was 20.6%. Male students had a 2.28 times higher likelihood of having BED symptoms compared to female counterparts (adjusted odds ratio [AOR] = 2.28; 95% CI: 1.33-3.89). Older students (AOR = 3.56, 95% CI: 1.80-7.05), students who were overweight or obese (AOR = 3.32, 95% CI: 1.87-5.89), and students reporting higher depressive symptoms (AOR = 2.69, 95% CI: 1.66-4.35) were at greater risk for developing BED compared to their respective counterparts.

Conclusions

This study provides new insights into the prevalence of BED symptoms and its contributing factors among Bangladeshi students. Approximately 1-in-5 university students reported having BED symptoms. University students who are older, overweight, or obese, and who report depressive symptoms may be at greatest risk. Future longitudinal studies are needed to determine the causal factors underlying BED. Findings from this study can assist policymakers and public health professionals in developing effective and targeted strategies to mitigate the risks associated with BED among Bangladeshi university students.

Effects of Geography on Risk for Future Suicidal Ideation and Attempts Among Children and Youth

Objective

Geography may influence the relationships of predictors for suicidal ideation (SI) and suicide attempts (SA) in children and youth.

Method

This is a nationwide retrospective cohort study of 124,424 individuals less than 25 years of age using commercial claims data (2011-2015) from the Health Care Cost Institute. Outcomes were time to SI or SA within 3 months after the indexed mental health or substance use disorder (MH/SUD) outpatient visit. Predictors included sociodemographic and clinical characteristics up to 3 years before the index event.

Results

At each follow-up time period, rates of SI and SA varied by the US geographic division (p < .001), and the Mountain Division consistently had the highest rates for both SI and SA (5.44%-10.26% for SI; 0.70%-2.82% for SA). Having MH emergency department (ED) visits in the past year increased the risk of SI by 28% to 65% for individuals residing in the New England, Mid-Atlantic, East North Central, West North Central, and East South Central Divisions. The main effects of geographic divisions were significant for SA (p<0.001). Risk of SA was lower in New England, Mid-Atlantic, South Atlantic, and Pacific (hazard ratios = 0.57, 0.51, 0.67, and 0.79, respectively) and higher in the Mountain Division (hazard ratio = 1.46).

Conclusion

To understand the underlying mechanisms driving the high prevalence of SI and SA in the Mountain Division and the elevated risk of SI after having MH ED visits, future research examining regional differences in risks for SI and SA should include indicators of access to MH ED care and other social determinants of health.

Obtaining long-term recovery: advances in optimizing treatment outcomes in patients with binge-eating disorder

INTRODUCTION

Binge-eating disorder (BED) is a complex and disabling eating disorder (ED) associated with considerable burden and impairments in quality of life and physical/mental health. It has been recognized as a formal ED category since 2013, however BED is still underdetected and undertreated.

AREAS COVERED

This review summarizes the advances in the understanding of the pathophysiology of BED as well as the evidence on the efficacy of the existing treatments. The authors searched Scopus, PubMed, ClinicalTrials.Gov, and ANZCTR with terms including 'assessment' OR 'treatment' OR 'diagnosis' OR 'mechanisms' AND 'binge eating' OR 'binge-eating disorder' for manuscripts published between January 2013 and April 2023.

EXPERT OPINION

Most of the trials on treatments of BED have been in people of high weight with weight loss as an outcome. Nevertheless, less is known about the treatment of this condition in people with body mass index (BMI) within the normal range where weight stabilization may be a more appropriate goal. Moreover, there is a need for an enhanced appreciation of the role of combination treatment to improve overall outcomes. Also, there are important opportunities for future research in understanding the mechanisms of action and effectiveness of BED treatments.

Suicidal behavior across a broad range of psychiatric disorders

Suicide is a leading cause of death worldwide. In 2020, some 12.2 million Americans seriously contemplated suicide, 3.2 million planned suicide attempts, and 1.2 million attempted suicide. Traditionally, the approach to treating suicidal behavior (SB) has been to treat the "underlying" psychiatric disorder. However, the number of diagnoses associated with SB is considerable. We could find no studies describing the range of disorders reported to be comorbid with SB. This narrative review summarizes literature documenting the occurrence of SB across the lifespan and the full range of psychiatric diagnoses, not only BPD and those that comprise MDE, It also describes the relevance of these observations to clinical practice, research, and nosology. The literature searches contained the terms "suicid*" and each individual psychiatric diagnosis and identified 587 studies. We did not include case reports, case series, studies only addressing suicidal ideation or non-suicidal self-injury (NSSI), studies on self-harm, not distinguishing between SB and NSSI and studies that did not include any individuals that met criteria for a specific DSM-5 diagnosis (n = 366). We found that SB (suicide and/or suicide attempt) was reported to be associated with 72 out of 145 diagnoses, although data quality varied. Thus, SB is not exclusively germane to Major Depressive Episode (MDE) and Borderline Personality Disorder (BPD), the only conditions for which it is a diagnostic criterion. That SB co-occurs with so many diagnoses reinforces the need to assess current and past SB regardless of diagnosis, and supports the addition of charting codes to the DSM-5 to indicate current or past SB. It also comports with new data that specific genes are associated with SB independent of psychiatric diagnoses, and suggests that SB should be managed with specific suicide prevention interventions in addition to treatments indicated for co-occurring diagnoses. SB diagnostic codes would help researchers and clinicians document and measure SB's trajectory and response to treatment over time, and, ultimately, help develop secondary and tertiary prevention strategies. As a separate diagnosis, SB would preclude situations in which a potentially life-threatening behavior is not accounted for by a diagnosis, a problem that is particularly salient when no mental disorder is present, as is sometimes the case.

Predictors of current suicidal ideation in a multi-diagnostic sample of individuals with eating disorders

BACKGROUND

Individuals with eating disorders (EDs) have high rates of suicidal ideation (SI) and attempts (SA). Fasting, body dissatisfaction, binge eating and purging have been associated with SI in non-clinical samples, individuals with anorexia nervosa or low-weight EDs, and a multi-diagnostic sample. However, few studies have examined how ED symptoms contribute to risk for SI in conjunction with other well-established risk factors, such as nonsuicidal self-injury (NSSI) and past SA. The aim of this study was to examine which ED symptoms contribute unique risk for current SI in a multi-diagnostic, clinical sample when statistically adjusting for gender, NSSI, past SA, and past SI.

METHODS

We conducted a chart review of 166 individuals who presented for ED treatment at an outpatient facility and signed informed consent. Initial intake interviews were coded for the presence versus absence of fasting, fear of weight gain, binge eating, purging, excessive exercise, restriction, body checking, self-weighing, and body dissatisfaction, as well as NSSI, past SA, past SI, and current SI.

RESULTS

A total of 26.5% of the sample endorsed current SI. In a logistic regression analysis, identifying as male (n = 17) or having a non-binary gender identity (n = 1), the presence of fasting, and past SI were all significantly associated with increased odds of current SI, whereas excessive exercise significantly decreased odds of current SI. Fasting was equally common across all diagnostic groups.

CONCLUSIONS

Future research should establish the temporal relationship between fasting and SI to better inform intervention.

Corticostriatal dynamics underlying components of binge-like consumption of palatable food in mice

Binge eating (BE) is a maladaptive repetitive feeding behavior present across nearly all eating disorder diagnoses. Despite the substantial negative impact of BE on psychological and physiological health, its underlying neural mechanisms are largely unknown. Other repetitive behavior disorders (e.g., obsessive compulsive disorder) show dysfunction within corticostriatal circuitry. However, to date, no work has investigated the in vivo neural dynamics underlying corticostriatal activity during BE episodes. The aim of the current study was to longitudinally examine in vivo neural activity within corticostriatal regions - the infralimbic cortex (IL) and dorsolateral striatum (DLS)- in a robust pre-clinical model for BE. Female C57BL6/J mice (N = 32) were randomized to receive: 1) intermittent (daily, 2-h) binge-like access to palatable food (sweetened condensed milk) (BE), or 2) continuous, non-intermittent (24-h) access to palatable food (control). In vivo calcium imaging was performed via fiber photometry at baseline and after chronic (4 weeks) engagement in the model for BE. Specific consummatory behaviors (feeding bout onset/offset) during recordings were captured using lickometers which generated TTL outputs for precise alignment of behavior to neural data. IL showed no specific changes in neural activity related to BE. However, BE animals showed decreased DLS activity at feeding onset and offset at the chronic timepoint when compared to activity at the baseline timepoint. Additionally, BE mice had significantly lower DLS activity at feeding onset and offset at the chronic timepoint compared to control mice. These results point to a role for DLS hypofunction in chronic BE, highlighting a potential target for future treatment intervention.

The association between eating disorders and mental health: an umbrella review

OBJECTIVE

There have been an increasing number of systematic reviews indicating the association between eating disorders (ED), including its risk factors, with mental health problems such as depression, suicide and anxiety. The objective of this study was to conduct an umbrella review of these reviews and provide a top-level synthesis of the current evidence in this area.

METHOD

A systematic search was performed using four databases (MEDLINE Complete, APA PyscInfo, CINAHL Complete and EMBASE). The inclusion criteria were systematic reviews (with or without meta-analysis), published in the English language between January 2015 and November 2022. The quality of the studies was assessed using the Joanna Briggs Institute Critical Appraisal tools for use of JBI Systematic reviews.

RESULTS

A total of 6,537 reviews were identified, of which 18 reviews met the inclusion criteria, including 10 reviews with meta-analysis. The average quality assessment score for the included reviews was moderate. Six reviews investigated the association between ED and three specific mental health problems: (a) depression and anxiety, (b) obsessive-compulsive symptoms and (c) social anxiety. A further 3 reviews focused on the relationship between ED and attention deficit hyperactivity disorder (ADHD) while 2 reviews focused on ED and suicidal-related outcomes. The remaining 7 reviews explored the association between ED and bipolar disorders, personality disorders, and non-suicidal self-injury. Depression, social anxiety and ADHD are likely to have a stronger strength of association with ED relative to other mental health problems.

DISCUSSION

Mental health problems such as depression, social anxiety and ADHD were found to be more prevalent among people suffering from eating disorders. Further research is necessary to understand the mechanism and health impacts of potential comorbidities of ED.

The association of weight control attempts with suicidality: The role of objective weight status and weight perception among adolescents of United States

BACKGROUND

The evidence for the association of weight control attempts with suicidality by objective weight status, subjective weight perception, and distorted weight perception among adolescents was limited.

METHODS

Data were extracted from a national representative sample of Youth Risk Behavior Surveys in the United States from 2011 to 2019. Binary logistic regression models with complex sampling designs were used to explore the association of weight control attempts, objective weight status, and weight perception with suicidality.

FINDINGS

The adolescents attempting to lose weight had higher weighted prevalence of suicidal ideation, suicide plan, suicide attempt, and suicide attempt with medical treatment compared with other attempts of weight control. Totally, attempting to lose weight was significantly associated with increased risk of suicidal ideation (OR: 1.17, 95%CI: 1.05-1.30) and suicide attempt (OR: 1.26, 95%CI: 1.10-1.46) when adjusting objective weight status, weight perception and all other covariates. In the subgroup analyses, attempting to lose weight was significantly associated with increased risk of suicidality in the adolescents of normal weight, underweight, perceived normal weight, perceived underweight, right estimation of objective weight status.

LIMITATIONS

Uncertain causal relationship existed because of cross-sectional design.

CONCLUSIONS

The risk of suicidality associated with weight control attempts varied among different subgroups. The findings in this study suggest that not only objective weight status but also weight perception should be with consideration when performing weight control attempts.

Identification of Risk Factors for Suicide and Insights for Developing Suicide Prevention Technologies: A Systematic Review and Meta-Analysis

Suicide is a termite that engulfs close to seven hundred thousand people worldwide each year. Existing work on risk factors that predict suicide lacks statistical associations, does not consider most countries, and has a wide range of risk factor domains. The goal of this systematic review and meta-analysis is to enhance our current understanding of suicidality by identifying risk factors that are most strongly associated with suicide and their impact on developing technological interventions for suicide prevention. A search strategy was carried out on four databases: (1) PsycINFO, (2) IEEE Xplore, (3) the ACM Digital Library, and (4) PubMed, and twenty-five studies were included based on the inclusion criteria. Factors statistically associated with suicide are any diagnosed mental disorder, adverse life events, past suicide attempts, low education level, loneliness or high levels of isolation, bipolar disorder, depression, multiple chronic health conditions, family history of suicide, sexual trauma, and being female. Domain-wise, comorbid disorders, and behavior-related risk factors are most strongly associated with suicide. We present a new hierarchical model of risk factors for suicide that advances our understanding of suicide and its causes. Finally, we present open research directions and considerations for developing suicide prevention technologies.

A school-based health centre partnership: Faculty practice, nursing student learning and wellness in youth, families and community

AIMS AND OBJECTIVES

This paper describes the development of a SBHC with an innovative model of care that grew out of a partnership between a public-school district and a university nursing programme in the midwestern region of the United States.

BACKGROUND AND PURPOSE

Persistent barriers to health and health care experienced by youth are well documented. School-based health centres (SBHCs) can improve educational and health outcomes, positively impacting health equity. Academic systems are positioned to address health care needs of the school-aged population, yet educators face challenges of accessing quality learning placements for students and faculty practice sites.

METHODS

A community-based collaborative methodology guided the planning phases that were driven by priority needs identified by families and stakeholders. With the mission of "partnering with students, families, and communities in the promotion of health and wellness through engagement in practice, education, and research," an ongoing dialogue over a two-year period led to articulating a vision, designing a plan and implementing a nurse-managed SBHC. The Standards for Reporting Qualitative Research (SRQR) checklist was considered in the preparation of this paper.

RESULTS

In three years, this SBHC has addressed and identified priority needs and served individual youth and families. The SBHC provides opportunities for the faculty to fulfil a practice requirement for certification and accreditation. Nursing students engage with youth and families in health education and health promotion while strengthening their technical and relational skills. Family nurse practitioner students gain valuable clinical experience. Faculty with expertise in family nursing guide family assessments, support family resiliency and direct therapeutic conversations with family units.

CONCLUSION

SBHCs serve youth, families, and community. This academic-practice partnership has the added benefit of providing faculty practice opportunities and nursing student experiential learning.

RELEVANCE TO CLINICAL PRACTICE

SHBCs provide practice opportunities that address needs in individuals, families, and communities. Partnerships should be considered at academic nursing programmes to support their needs and fulfil commitments to address health equity gaps.

Lived experience perspectives on a definition of eating disorder recovery in a sample of predominantly white women: a mixed method study

BACKGROUND

There has recently been a push for recovery-focused research in the eating disorder (ED) field, starting with a consensus definition of recovery. One definition, in particular, proposed by Bardone-Cone et al. [21] has received considerable attention given its transdiagnostic nature and validation studies. However, no studies to date have elicited lived experience views of this definition. The goal of the current study was to examine perspectives on this definition of recovery from individuals with a past or present ED and to determine whether participant agreement with the model differed based on diagnostic history or current symptom severity.

METHODS

Sixty-two individuals (95.2% women; 91.9% White/European) participated in a 1-2 h interview aimed at capturing their perspectives on ED recovery. Transcripts were analyzed using qualitative content analysis and codebook thematic analysis to examine agreement with and thoughts on Bardone-Cone's definition of recovery, respectively. Chi-squared tests of independence and binary logistic regression were computed to determine whether agreement with the definition differed across diagnostic history and self-reported symptoms.

RESULTS

Although some participants indicated acceptance of the definition, the majority expressed concerns related to its categorical nature, proposed criteria, feasibility, language, and applications. There were no differences in acceptance based on diagnostic history or current symptom severity.

CONCLUSION

A single definition of recovery does not seem to fit individuals' lived ED experience. Future research may benefit from distinguishing between recovery as an individually-defined phenomenon and related constructs such as remission (i.e., loss of diagnosis or absence of clinical symptoms). A more comprehensive multi-faceted, and person-centered model of recovery may have merit in clinical settings.

Examining associations between symptoms of eating disorders and symptoms of anxiety, depression, suicidal ideation, and perceived family functioning in university students: A brief report

OBJECTIVE

We examined the relationships between eating disorders symptoms (EDs), suicidal ideation, depressive and anxiety symptoms, and perceived family functioning in a sample of university students aged 18-25 years (N = 397).

METHOD

Assessment of symptoms was carried out with the Eating Disorder Diagnostic Scale, Beck Anxiety Inventory and Beck Depression Inventory, among others. We explored the associations between the domains using network analysis.

RESULTS

We found that physical anxiety symptoms, followed by cognitive and physical depressive symptoms showed the greatest centrality in the current network. Perceived family functioning was negatively related to eating disorder symptoms.

DISCUSSION

We provide evidence regarding the relevant role of anxiety and depression symptoms in the presentation of ED symptoms in university students. These findings provide new insights to improve preventive interventions to timely reduce symptoms and risk factors associated with EDs.

PUBLIC SIGNIFICANCE

Using a network approach, we found specific associations between physical anxiety symptoms, cognitive and physical depressive symptoms, eating disorders symptoms, suicidal ideation and perceived family functioning in university students. These variables can be potential targets to develop evidence-based preventive strategies in this population. A better understanding of these complex associations and the role of family variables could enhance the effectiveness of interventions in both clinical and educational settings.

Breaking It Down: Investigation of Binge Eating Components in Animal Models to Enhance Translation

Binge eating (BE) is a core eating disorder behavior that is present across nearly all eating disorder diagnoses (e. g., bulimia nervosa, binge eating disorder, anorexia nervosa binge/purge subtype), and is also widely present in the general population. Despite the prevalence of BE, limited treatment options exist and there are often high rates of relapse after treatment. There is evidence showing that genetic factors contribute to the heritability of BE and support for biological contributions to BE. However, more work is needed to fully understand neurobiological mechanisms underlying BE. One approach to target this problem is to separate BE into its distinct clinical components that can be more easily modeled using pre-clinical approaches. To date, a variety of animal models for BE have been used in pre-clinical studies; but there have been challenges translating this work to human BE. Here, we review these pre-clinical approaches by breaking them down into three clinically-significant component parts (1) consumption of a large amount of food; (2) food consumption within a short period of time; and (3) loss of control over eating. We propose that this rubric identifies the most frequently used and effective ways to model components of BE behavior using pre-clinical approaches with the strongest clinical relevance. Finally, we discuss how current pre-clinical models have been integrated with techniques using targeted neurobiological approaches and propose ways to improve translation of pre-clinical work to human investigations of BE that could enhance our understanding of BE behavior.

Presence and severity of suicidal thoughts and behaviors across the eating disorder diagnostic spectrum: A pilot study

OBJECTIVES

There is a dearth of research on suicidal thoughts and behaviors among eating disorder patients diagnosed with binge eating disorder (BED) or other specified feeding or eating disorder (OSFED). This pilot study evaluated presence and severity of suicidal thoughts and behaviors by eating disorder diagnosis in a transdiagnostic clinical eating disorder sample.

METHODS

Participants were individuals (N = 257; 91.1% female; 94.6% Caucasian) currently receiving eating disorder treatment for anorexia nervosa (AN), bulimia nervosa (BN), BED, or OSFED. Participants completed online measures of variables.

RESULTS

Lifetime and current presence and severity of suicidal ideation and suicide attempts were statistically similar among diagnostic groups.

CONCLUSION

Though largely overlooked, treatment-utilizing individuals with BED and OSFED may experience elevated rates and severity of suicidal thoughts and behaviors, like those with AN and BN. Attention to suicide-related risk assessment and management is needed when treating individuals with eating disorders, regardless of diagnosis.

"I am the embodiment of an anorexic patient's worst fear": Severe obesity and binge eating disorder on a restrictive eating disorder ward

Adolescents who have been diagnosed with an eating disorder commonly have comorbid mental health conditions which have a significant impact on illness trajectory and may even limit access to effective treatment. Current models of eating disorder care focus mainly on treatment for patients diagnosed with restrictive eating disorders with fewer options available for those with binge eating disorder. We describe a case of an adolescent living with severe, complex obesity and binge eating disorder, presenting in a mental health crisis, admitted to an in-patient unit primarily for patients being treated for restrictive eating disorders such as anorexia nervosa. This case report describes multiple challenges that arose in admitting such a patient on a ward specializing in the treatment of restrictive eating disorders and highlights the need for equitable and more accessible care for patients living with all types of eating disorders.

School health class associated with reduced odds of eating disorder symptoms in American adolescents

OBJECTIVE

Eating disorder symptoms, including eating disorder diagnosis, binge eating, and unhealthy weight loss, are associated with health risks, and adolescence may be an optimal time to provide education on healthy alternatives. This research explored whether in-school health information during adolescence is associated with eating disorder symptoms in young adulthood.

METHOD

Data were used from the National Longitudinal Study of Adolescent to Adult Health, a nationally representative study of American youth, including information from Wave I, when participants were in Grades 7-12, and from Wave III, when participants were aged 18-26. Logistic regression analyses predicted eating disorder symptoms from in-school health information, adjusting for demographic and educational covariates. In-school health information and eating disorder symptoms were based on participant self-report.

RESULTS

In-school health information about both diet (the foods you should and should not eat) and the importance of exercise compared to no health information reduced the odds of youth-reported eating disorder history odds ratio ((OR) = 0.23, 95% CI = 0.11-0.48). Individuals who received information on exercise alone compared to no health information were also less likely to use weight pills to control weight (OR = 0.26, 95% CI = 0.11-0.61). There was no difference in binge-eating symptoms based on school health class.

DISCUSSION

Findings from this exploratory research study indicate that in-school receipt of information on diet and exercise has modest associations with eating disorder symptoms, including lower odds of a self-reported eating disorder and lower odds of using weight loss pills. Further research is needed to definitely test the role of school health class on eating disorder symptoms.

Understanding suicide risk and eating disorders in college student populations: Results from a National Study

OBJECTIVE

To examine suicide risk by eating disorder severity and symptom presentation in a nationwide sample of college students.

METHOD

The Healthy Minds Study is the largest mental health survey of college populations in the United States. We analyzed the most recent available data (2015-2017) with 71,712 randomly selected students from 77 campuses. We estimated associations between two measures of suicidality (ideation and attempts) and three validated measures of eating disorder symptoms (the SCOFF, weight concerns scale, and the eating disorder examination questionnaire binge and purge items). Importantly, we also controlled for co-occurring symptoms of depression and anxiety, based on validated screening tools. The large, diverse sample provided a unique opportunity to assess whether certain individual characteristics were associated with increased risk.

RESULTS

Eating disorder symptoms, even at subthreshold levels, were highly predictive of suicidality. Relative to students with no apparent eating disorder symptoms, students with the highest symptom levels (a SCOFF score of 5) had 11 times higher odds of attempting suicide, while those with subthreshold symptoms had two times higher odds. We also observed a strong association between suicide attempts and eating disorder presentations that included purging. Students from marginalized backgrounds, particularly gender and sexual minorities, were at increased risk for suicide and eating disorders.

DISCUSSION

In the largest known study to date, findings suggest that eating disorders should be a priority within broader campus suicide prevention efforts, should be assessed along a continuum of severity and symptom presentation, and should focus on reaching vulnerable students.

Suicide attempts in US adults with lifetime DSM-5 eating disorders

BACKGROUND

Rates of suicide are increasing in the US. Although psychiatric disorders are associated with suicide risk, there is a dearth of epidemiological research on the relationship between suicide attempts (SAs) and eating disorders (EDs). The study therefore aimed to examine prevalence and correlates of SAs in DSM-5 EDs-anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED)-in a nationally representative sample of US adults. In addition, prevalence and correlates of SAs were examined in the two subtypes of AN-restricting (AN-R) and binge/purge (AN-BP) types.

METHODS

The study included 36,171 respondents in the Third National Epidemiological Survey on Alcohol and Related Conditions (NESARC-III) who completed structured diagnostic interviews (AUDADIS-5) and answered questions regarding SA histories and psychosocial impairment associated with EDs. We evaluated lifetime prevalence of SA, psychosocial impairment, clinical profiles, and psychiatric comorbidity in adults with EDs with and without SA histories, and temporal relationships between age onset of SA and EDs.

RESULTS

Prevalence estimates of suicide attempts were 24.9% (for AN), 15.7% (for AN-R), 44.1% (for AN-BP), 31.4% (for BN), and 22.9% (for BED). Relative to respondents without specific EDs, adjusted odds ratios (AORs) of SAs were significantly greater in all EDs: AN = 5.40 (95% confidence intervals [CIs] = 3.80-7.67), AN-R = 3.16 (95% CIs = 1.82-5.42), AN-BP = 12.09 (95% CIs = 6.29-23.24), BN = 6.33 (95% CIs = 3.39-11.81), and BED = 4.83 (95% CIs = 3.54-6.60). Among those with SA history, mean age at first SA and number of SAs were not significantly different across the specific EDs. SA was associated with significantly earlier ED onset in BN and BED, longer duration of AN but shorter duration of BN, greater psychosocial impairment in AN and BN, and with significantly increased risk for psychiatric disorder comorbidity across EDs. Onset of BED was significantly more likely to precede SA (71.2%) but onsets of AN (50.4%) and BN (47.6%) were not.

CONCLUSIONS

US adults with lifetime DSM-5 EDs have significantly elevated risk of SA history. Even after adjusting for sociodemographic factors, those with lifetime EDs had a roughly 5-to-6-fold risk of SAs relative to those without specific EDs; the AN binge/purge type had an especially elevated risk of SAs. SA history was associated with distinctively different clinical profiles including greater risk for psychosocial impairment and psychiatric comorbidity. These findings highlight the importance of improving screening for EDs and for suicide histories.

Suicide attempts in eating disorder subtypes: a meta-analysis of the literature employing DSM-IV, DSM-5, or ICD-10 diagnostic criteria

BACKGROUND

Quantification of suicidal risk in specific populations is important for the adoption of targeted prevention and harm reduction measures. Though there remains little systematic evidence, risk of suicide attempts for bulimia nervosa (BN) and binge-purging anorexia nervosa (AN-bp) appears higher than restrictive AN (AN-r); risk in binge eating disorder (BED) is still unclear. The aim of this meta-analysis was to compare proportions of suicide attempts in eating disorder (ED) subgroups.

METHODS

A literature search using combinations of key-words for ED and suicide attempts was performed. Studies reporting proportions of suicide attempters in at least two ED groups, diagnosed according to DSM-IV or -5 and ICD-10 diagnostic criteria were considered. ED subgroups were analyzed in pairs using a binary random effect model for proportions. Publication bias, meta-regression, and sensitivity analyses were performed.

RESULTS

In BN, attempted suicide was more frequent (21%) than in AN (12.5%), but the difference was statistically significant only when BN was compared with AN-r (9-10%). In BED, the proportion of suicide attempts was as high as in AN (10-12%).

CONCLUSIONS

Though limited by heterogeneity across the studies in terms of methodology and aims, inability to control for relevant confounding variables, exclusion of ED not otherwise specified, this study supports suicide attempts as a major issue in EDs, especially in binge-purging subtypes, i.e. BN and AN-bp. Similar suicidal proportions were observed in AN and BED. The reasons for a greater proportion of attempted suicide in binge/purging subtypes need to be explored in future studies.

Lifestyle Interventions and Prevention of Suicide

Over the past years, there has been a growing interest in the association between lifestyle psychosocial interventions, severe mental illness, and suicide risk. Patients with severe mental disorders have higher mortality rates, poor health states, and higher suicide risk compared to the general population. Lifestyle behaviors are amenable to change through the adoption of specific psychosocial interventions, and several approaches have been promoted. The current article provides a comprehensive review of the literature on lifestyle interventions, mental health, and suicide risk in the general population and in patients with psychiatric disorders. For this purpose, we investigated lifestyle behaviors and lifestyle interventions in three different age groups: adolescents, young adults, and the elderly. Several lifestyle behaviors including cigarette smoking, alcohol use, and sedentary lifestyle are associated with suicide risk in all age groups. In adolescents, growing attention has emerged on the association between suicide risk and internet addiction, cyberbullying and scholastic and family difficulties. In adults, psychiatric symptoms, substance and alcohol abuse, weight, and occupational difficulties seems to have a significant role in suicide risk. Finally, in the elderly, the presence of an organic disease and poor social support are associated with an increased risk of suicide attempt. Several factors may explain the association between lifestyle behaviors and suicide. First, many studies have reported that some lifestyle behaviors and its consequences (sedentary lifestyle, cigarette smoking underweight, obesity) are associated with cardiometabolic risk factors and with poor mental health. Second, several lifestyle behaviors may encourage social isolation, limiting the development of social networks, and remove individuals from social interactions; increasing their risk of mental health problems and suicide.
