Avaliação da influência da pandemia de Covid-19 no risco de desenvolvimento de transtornos alimentares em mulheres / Assessment of the influence of the Covid-19 pandemicon the risk of developing eating disorders in women

Objetivo: verificar a influência da pandemia de Covid-19 no risco de desenvolvimento de transtornos alimentares em mulheres. Metodologia: pesquisa quantitativa, com mulheres com acesso ao computador, a celular e à internet. A coleta de dados foi realizada a partir de um questionário on-line contendo 60 perguntas, com respostas fechadas, que visavam conhecer a sua relação com a alimentação. Foram verificados o consumo alimentar e o risco de desenvolvimento de anorexia nervosa (Eating Attitudes Test - EAT-26) e bulimia nervosa (Bulimic Investigatory Test, Edinburgh- BITE). Resultados: participaram da pesquisa 92 mulheres, sendo que 81,50% (n=75) referiram que ficaram em casa durante a pandemia. Sobre a ingestão de alimentos, 45,70% (n=42) relataram que consumiram diariamente frutas e hortaliças, 55,40% (n=51) ingeriram de 1 a 2 vezes/semana bolachas, salgadinhos, doces e guloseimas e 62,00% (n=57) consumiam embutidos pelo menos 1 vez/semana. Ainda, 18,50% (n=17) apresentaram risco para o desenvolvimento de anorexia nervosa e 83,60% (n=73) risco de bulimia nervosa. Entretanto, analisando se esse risco estava associado à pandemia, verificou-se que não houve diferença significativa entre o grupo que permaneceu em casa e o grupo que saiu para trabalhar (p > 0,05). Conclusão: portanto, grande parte das voluntárias apresentaram um risco de desenvolver algum transtorno alimentar, entretanto, não houve uma relação entre o possível risco de desenvolver transtornos alimentares influenciado pela pandemia.

Objective: to verify the influence of the Covid-19 pandemic on the risk of developing eating disorders in women. Methodology: quantitative research, with women with access to a computer, cell phone and internet. Data collection was carried out using an online questionnaire containing 60 questions, with closed answers, which aimed to understand their relationship with food. Food consumption Abstract and the risk of developing nervous anorexia (Eating Attitudes Test - EAT-26) and nervous bulimia (Bulimic Investigatory Test, Edinburgh - BITE) were verified. Results: 92 women participated in the research, with 81.50% (n=75) reporting that they stayed at home during the pandemic. Regarding food intake, 45.70% (n=42) reported that they consumed fruits and vegetables daily, 55.40% (n=51) ate cookies, snacks, sweets and sweets 1 to 2 times/week and 62, 00% (n=57) consumed sausages at least once/week. Furthermore, 18.50% (n=17) were at risk for developing nervous anorexia and 83.60% (n=73) were at risk for nervous bulimia. However, analyzing whether this risk was associated with the pandemic, it was found that there was no significant difference between the group that remained at home and the group that went out to work (p > 0.05). Conclusion: therefore, most of the volunteers presented a risk of developing an eating disorder, however, there was no relationship between the possible risk of developing eating disorders influenced by the pandemic.

Longitudinal Impact of Disordered Eating Attitudes on Depression, Anxiety, and Somatization in Young Women with Anorexia and Bulimia.

Background/Objectives: Eating disorders, characterized by severe disturbances in eating behavior, are a public health concern, particularly among young women. This longitudinal study aimed to investigate the relationship between disordered eating attitudes and mental health outcomes, including depression, anxiety, and somatization, among individuals with eating disorders. Methods: A total of 471 young German women hospitalized with anorexia nervosa or bulimia nervosa participated in this study. Assessments were conducted at two points over a two-month interval using the Eating Disorder Inventory-2 (EDI-2) and the Patient Health Questionnaire. Regression analyses were performed to determine predictors of depression, anxiety, and somatization. The study controlled for socio-demographic segmentation using Sinus-Milieus, a social classification system, as a covariate. Results: Regression analyses revealed that interpersonal distrust and impulse regulation were significant predictors of subsequent depression. Impulse regulation strongly predicted subsequent anxiety, while both impulse regulation and social insecurity were strong predictors of subsequent somatization. The Neo-Ecological Milieu emerged as the most prevalent socio-demographic group (34.4% of participants). The Sinus-Milieus segmentation, however, did not significantly impact the health outcomes, suggesting consistent mental health issues across socio-demographic groups. Conclusions: This study's findings underscored the role of disordered eating attitudes in predicting mental health outcomes among young women with eating disorders. Addressing these attitudes in therapeutic settings may help mitigate symptoms of not only the primary condition but also depression, anxiety, and somatization.

Association of OPRD1 Gene Variants with Changes in Body Weight and Psychometric Indicators in Patients with Eating Disorders.

Objectives: This study aimed to investigate whether genetic variations in the OPRD1 gene affect psychopathological symptoms and personality dimensions in eating disorders (ED) patients and/or contribute to ED risk. Methods: The study involved 221 female patients with anorexia nervosa (AN), 88 with bulimia nervosa (BN), and 396 controls. Sixteen tag-single nucleotide polymorphisms (SNPs) in OPRD1 were identified. Psychometric evaluations were conducted using the Symptom Checklist 90 Revised (SCL-90R) and the Eating Disorders Inventory Test-2 (EDI-2). p-values obtained by regression models were corrected for multiple testing by the False Discovery Rate (FDR) method. Results: In AN patients, genotypes rs204077TT and rs169450TT were linked to lower body-mass index (BMI) values (FDR-q = 0.035 and 0.017, respectively), as was rs2234918 in a log-additive model (BMI: 18.0 ± 0.28, 17.22 ± 0.18 and 16.59 ± 0.39 for TT, TC and CC carriers, FDR-q = 0.012). Additionally, AN patients carrying the rs72665504AA genotype had higher scores in interpersonal distrust (FDR-q = 0.030), whilst BN carriers of rs513269TT and rs2873795TT showed lower scores in ineffectiveness (FDR-q = 0.041 and FDR-q = 0.021). In the AN group, BMI correlated with variability in a distal haplotype (rs508448/rs204077/rs223491, FDR-q = 0.028), which was also associated with the global positive symptom total (PST) index of SCL-90R (FDR-q = 0.048). Associations were more noticeable in BN patients; again, the distal region of the gene was linked to EDI-2 total scores (FDR-q = 0.004-0.048 for the four last haplotypes) and two global SCL-90R indices (GSI: FDR-q = 0.011 and positive symptom distress index (PSDI): FDR-q = 0.003 for the last s204077/rs2234918/rs169450 combination). No associations with ED risk were observed. Conclusions: Genetic variation in the OPRD1 gene, particularly in its distal region, is associated with BMI and psychopathological comorbidities in ED patients.

How Do Patients and Their Supports Experience Temperament Based Therapy With Support (TBT-S)? A Qualitative Study.

BACKGROUND: Temperament Based Therapy with Support (TBT-S) is an emerging intervention based on empirically supported neurobiological models. Due to its novelty, only a handful of studies to date have examined TBT-S, and none of these previous studies have provided a qualitative evaluation of how TBT-S is perceived by the target population. Therefore, the aim of the current study was to provide an increased understanding of how TBT-S is experienced by patients with an eating disorder and their supports. METHOD: Forty-six patients with an eating disorder and 63 supports consented to be included in the study. The participants provided written responses to six open-ended questions during the post-treatment assessment, detailing their treatment experiences and offering additional feedback. Thematic analysis (TA) was used to analyze their written responses, aiming for a combination of latent and semantic themes. RESULTS: The results reveal a substantial overlap between patients' and supports' experiences with TBT-S. In both groups, identified themes suggest increased knowledge and hopefulness as key benefits of the intervention. While both patients and support persons considered TBT-S to be worthwhile, patients also reported finding the intervention quite challenging. Additionally, both groups emphasized the neurobiological rationale as an essential component of TBT-S. CONCLUSIONS: The qualitative evaluations from this study offer new insights into how TBT-S is experienced by the target population. The findings provide an opportunity to incorporate participant suggestions for improving the treatment, and serve as an important building block for future studies aimed at assessing the effectiveness of TBT-S as an augmentation to treatment-as-usual.

Maternal sex-hormone exposure and the risk of eating disorders in daughters.

Potential effects of prenatal sex hormones on later eating disorders in offspring have been investigated with two indirect methods (finger length ratio, opposite- versus same-sex twins). We utilized a direct, prospective method, examining the association between prenatal sex-hormones in maternal sera and the risk of bulimia nervosa (BN) and anorexia nervosa (AN) among daughters. Females with BN (55), AN (150), sister controls without eating disorders (one per case), and population controls (one per case) were derived from Finnish registers. Maternal gestational testosterone and estradiol levels were assayed from archived specimens stored in a national serum biobank. When females with BN were compared to their sister controls, those with higher gestational testosterone levels were at an increased risk of BN. No significant associations with BN were found when the comparison was made to population controls, and when estradiol levels and testosterone/estrogen ratio were assessed. We neither found associations between gestational sex-hormone levels and the risk of AN. Among females with familial liability for BN, higher gestational testosterone exposure may have a role in later development of BN, whereas lower testosterone exposure may have a protective effect. We found no evidence for the involvement of gestational sex-hormones in the etiology of AN.

Relationship between nonexercise activity and mood in patients with eating disorders.

INTRODUCTION: Many patients with eating disorders (EDs) engage in excessive and compulsive physical activity (pathological exercise, PE) to regulate negative mood or to "burn calories." PE can lead to negative health consequences. Non-exercise activity (NEA) bears the potential to serve as intervention target to counteract PE and problematic eating behaviors since it has been associated with positive mood effects. However, to date, there is no investigation on whether the positive link between NEA and mood seen in the healthy translates to patients with ED. MATERIAL AND METHODS: To study potential associations of NEA and mood in ED, we subjected 29 ED-patients and 35 healthy controls (HCs) to an ambulatory assessment study across 7 days. We measured NEA via accelerometers and repeatedly assessed mood on electronic smartphone diaries via a mixed sampling strategy based on events, activity and time. Within- and between-subject effects of NEA on mood, PE as moderator, and the temporal course of effects were analyzed via multilevel modeling. RESULTS: NEA increased valence (ß = 2.12, p < 0.001) and energetic arousal (ß = 4.02, p < 0.001) but showed no significant effect on calmness. The effects of NEA on energetic arousal where significantly stronger for HCs (ßHC = 6.26, p < 0.001) than for EDs (ßED = 4.02, p < 0.001; ßinteraction = 2.24, p = 0.0135). Effects of NEA were robust across most timeframes of NEA and significantly moderated by PE, that is, Lower PE levels exhibited stronger NEA effects on energetic arousal. CONCLUSION: Patients with ED and HC show an affective benefit from NEA, partly depending on the level of PE. If replicated in experimental daily life studies, this evidence may pave the way towards expedient NEA interventions to cope with negative mood. Interventions could be especially promising if delivered as Just-in-time adaptive interventions (JITAIs) and should be tailored according to the PE level.

Enhanced cognitive behaviour therapy for adolescents with eating disorders: development, effectiveness, and future challenges.

Eating disorders can significantly impact the psychosocial functioning and physical health of adolescents. Early and effective treatment is crucial to prevent long-lasting and potentially devastating adverse effects. The National Institute for Health and Care Excellence has recommended cognitive behaviour therapy (CBT) for eating disorders in adolescents when family therapy is unacceptable, contraindicated, or ineffective. This recommendation was primarily based on the review of promising results from the enhanced version of CBT (CBT-E) adapted for adolescents with eating disorders aged between 12 and 19 years. A non-randomized effectiveness trial has also shown that CBT-E achieved a similar outcome to family-based treatment (FBT) at 6- and 12-months. CBT-E has several advantages. It is acceptable to young people, and its collaborative nature suits ambivalent young patients who may be particularly concerned about control issues. The transdiagnostic scope of the treatment is an advantage as it can treat the full range of disorders that occur in adolescent patients. It is an individual one-on-one treatment that does not necessitate the full involvement of the family. This approach is particularly beneficial for families that can only provide limited support. Future challenges include clarifying the relative efficacy of CBT-E and family therapy for the treatment of adolescent patients with eating disorders in a randomized control trial and increasing its effectiveness, identifying the reasons for the lack of response, and modifying the treatment accordingly.

Difficulties in Emotion Regulation in Avoidant/Restrictive Food Intake Disorder.

OBJECTIVE: Despite substantial research indicating difficulties with emotion regulation across eating disorder presentations, emotion regulation has yet to be studied in adults with avoidant/restrictive food intake disorder (ARFID). We hypothesized that (1) those with ARFID would report greater overall emotion regulation difficulties than nonclinical participants, and (2) those with ARFID would not differ from those with other eating disorders on the level of emotion regulation difficulty. METHODS: One hundred and thirty-seven adults (age 18-30) from an outpatient clinic with ARFID (n = 27), with other primarily restrictive eating disorders (e.g., anorexia nervosa; n = 34), and with binge/purge eating disorders (e.g., bulimia nervosa; n = 51), as well as nonclinical participants (n = 25) recruited via Amazon Mechanical Turk (MTurk) completed the Difficulties in Emotion Regulation Scale (DERS). We compared DERS scores across groups. RESULTS: In line with expectations, patients with ARFID scored significantly higher than nonclinical participants on the DERS Total (p = 0.01) with a large effect size (d = 0.87). Also as hypothesized, those with ARFID did not differ from those with other primarily restrictive (p = 0.99) or binge/purge disorders (p = 0.29) on DERS Total. DISCUSSION: Adults with ARFID appear to exhibit emotion regulation difficulties which are greater than nonclinical participants, and commensurate with other eating disorders. These findings highlight the possibility of emotion regulation difficulties as a maintenance mechanism for ARFID.

Parental Binge Eating and Child Binge Eating and Weight-Control Behaviors: Cross-Sectional and Longitudinal Findings From the EAT 2010-2018 Study.

OBJECTIVE: In cross-sectional and retrospective research, parental binge eating is associated with their children's eating psychopathology. The current study extended the evidence by cross-sectionally and longitudinally examining the relation between parental binge eating and binge eating and weight-control behaviors in the next generation of their adolescent children and young adult children in a population-based sample. METHODS: Adolescents (Time 1: M = 14.5, SD = 2.0 years) (n = 2367), followed into adulthood (Time 2: M = 22.1, SD = 2.0 years), and their parents (n = 3664) were enrolled in EAT 2010-2018 and Project F-EAT 2010. The current study examined parental binge eating, and child binge eating and weight-control behaviors. Adjusted models covaried for child gender, age, and race/ethnicity. RESULTS: Approximately 7% of adolescents at Time 1 had at least one parent who reported binge eating with no differences by child's age, gender, or race/ethnicity. Having at least one parent experiencing binge eating at Time 1 (vs. not) was associated cross-sectionally with adolescent children's use of extreme weight-control behaviors (9.6% vs. 4.8%; Risk Difference [RD] = 4.9%) and associated longitudinally with binge eating during young adulthood (21.1% vs. 11.6%; RD = 9.5%). Other associations did not reach statistical significance. CONCLUSIONS: Children of parents with binge eating appear to have elevated risk of extreme weight-control behaviors during adolescence and binge eating in young adulthood. Clinicians should assess whether eating psychopathology extends to other family members, and offer additional support to parents with binge eating. Further research is needed to identify risk factors in the children of parents with binge eating and to assess strategies for prevention.

Caregivers' depressive symptoms and eating disorder severity in adults with anorexia and bulimia nervosa.

BACKGROUND: Negative affectivity of caregivers has been linked to difficulties in the caregiver-patient relationship and it is assumed to contribute to the maintenance of eating disorder (ED) symptoms. AIMS: The present study investigated the relationship of patients' ED symptom severity to patients' and caregivers' depressive symptoms, and caregivers' involvement in a mixed sample of adult inpatients with anorexia (AN) and bulimia nervosa (BN), as well as their caregivers. METHOD: The Eating Disorder Examination and Beck Depression Inventory (BDI) were administered to 55 adult ED patients (26 AN and 29 BN), and the BDI as well as the Involvement Evaluation Questionnaire were filled in by one caregiver of each patient. RESULTS: Our results showed caregivers' depressive symptoms to be significantly related to patients' ED symptom severity, however depressive symptoms and ED symptoms of patients were not related. No connection of involvement of caregivers and ED severity of patients was found. AN and BN patients did not significantly differ on ED severity or depressive symptoms. Caregivers of AN and BN patients did not differ significantly on depressive symptoms and involvement. CONCLUSIONS: Our results support the importance of mental health support for caregivers of adults with AN and BN.

Increased Prevalence of Binge Eating Disorder and Bulimia Nervosa in Women With Polycystic Ovary Syndrome: A Systematic Review and Meta-Analysis.

CONTEXT: Polycystic ovary syndrome (PCOS) is associated with disordered eating/eating disorders, but prior meta-analyses are limited by small numbers. OBJECTIVE: To inform the 2023 International PCOS Guideline, we performed a systematic review and meta-analysis evaluating the prevalence of disordered eating/eating disorders among women with and without PCOS. METHODS: Ovid MEDLINE, EMBASE, PsycInfo, and All EMB were searched from inception through February 1, 2024, for studies that compared prevalences of eating disordered/disordered eating in adolescent or adult women. Random effects meta-analyses were used to estimate the pooled odds ratios (OR) or standardized mean differences (SMD) of outcomes in women with PCOS compared to controls. Methodological quality was assessed by the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system, and included studies were assessed for risk of bias. RESULTS: Of 1352 articles identified, 20 were included, with a total of 28 922 women with PCOS and 258 619 controls. Individuals with PCOS had higher odds of any eating disorder (OR: 1.53 [1.29, 1.82], 8 studies), which persisted in studies where PCOS was diagnosed by Rotterdam criteria (OR: 2.88 [1.55, 5.34], 4 studies). Odds of bulimia nervosa, binge eating disorder, and disordered eating, but not anorexia nervosa, were increased in PCOS. Mean disordered eating scores were higher in PCOS (SMD: 0.52 [0.28, 0.77], 13 studies), including when stratified by normal and higher weight body mass index. Most included studies were of moderate quality, with no evidence of publication bias. CONCLUSION: Our study informs the 2023 PCOS Guideline recommendations for consideration of the risk of disordered eating/ eating disorders in care of women with PCOS, regardless of weight, especially during providing lifestyle counseling.

Evaluation of Subjective and Objective Voice Characteristics in Patients With Bulimia Nervosa.

OBJECTIVE: The present study aims to examine subjectively and objectively the voice changes in bulimia nervosa (BN) patients at different stages of treatment. METHOD: The study was conducted with a study group including 10 patients followed up with a diagnosis of BN and a control group consisting of 10 healthy participants of a similar age group without eating disorders. The Reflux Symptom Index (RFS) was used for stroboscopic evaluation. The fundamental frequency (F0), jitter, shimmer, and noise-to-harmonics ratio were determined during acoustic voice analysis. Maximum phonation time was analyzed. A subjective evaluation was performed using the Voice Handicap Index-10 (VHI-10). RESULTS: Jitter, shimmer, VHI-10 score, and RFS values showed a statistically significant difference in the patient and control groups (P < 0.05). The mean values of jitter, shimmer, VHI-10 score, and RFS were higher in the patient group than in the control group. Maximum phonation time did not differ between groups (P > 0.05) Age and F0 (Hz) values showed no statistically significant difference in the patient and control groups (P > 0.05). CONCLUSIONS: In BN patients, the laryngopharyngeal reflux mechanism causes negative effects on vocal cord examination and acoustic sound analysis parameters, leading to subjective dissatisfaction.

Oculomotor behaviors in youth with an eating disorder: findings from a video-based eye tracking task.

BACKGROUND: The oculomotor circuit spans many cortical and subcortical areas that have been implicated in psychiatric disease. This, combined with previous findings, suggests that eye tracking may be a useful method to investigate eating disorders. Therefore, this study aimed to assess oculomotor behaviors in youth with and without an eating disorder. METHODS: Female youth with and without an eating disorder completed a structured task involving randomly interleaved pro-saccade (toward at a stimulus) and anti-saccade (away from stimulus) trials with video-based eye tracking. Differences in saccades (rapid eye movements between two points), eye blinks and pupil were examined. RESULTS: Youth with an eating disorder (n = 65, Mage = 17.16 ± 3.5 years) were compared to healthy controls (HC; n = 65, Mage = 17.88 ± 4.3 years). The eating disorder group was composed of individuals with anorexia nervosa (n = 49), bulimia nervosa (n = 7) and other specified feeding or eating disorder (n = 9). The eating disorder group was further divided into two subgroups: individuals with a restrictive spectrum eating disorder (ED-R; n = 43) or a bulimic spectrum eating disorder (ED-BP; n = 22). In pro-saccade trials, the eating disorder group made significantly more fixation breaks than HCs (F(1,128) = 5.33, p = 0.023). The ED-BP group made the most anticipatory pro-saccades, followed by ED-R, then HCs (F(2,127) = 3.38, p = 0.037). Groups did not differ on rate of correct express or regular latency pro-saccades. In anti-saccade trials, groups only significantly differed on percentage of direction errors corrected (F(2, 127) = 4.554, p = 0.012). The eating disorder group had a significantly smaller baseline pupil size (F(2,127) = 3.60, p = 0.030) and slower pro-saccade dilation velocity (F(2,127) = 3.30, p = 0.040) compared to HCs. The ED-R group had the lowest blink probability during the intertrial interval (ITI), followed by ED-BP, with HCs having the highest ITI blink probability (F(2,125) = 3.63, p = 0.029). CONCLUSIONS: These results suggest that youth with an eating disorder may have different oculomotor behaviors during a structured eye tracking task. The oculomotor behavioral differences observed in this study presents an important step towards identifying neurobiological and cognitive contributions towards eating disorders.

Video based eye tracking is a promising method for studying differences between individuals with and without a psychiatric disease of interest. While some studies have explored oculomotor behaviors in individuals with an eating disorder, much remains unknown. The present study investigated saccades (fast eye movements between two points), eye blinks and pupil responses between female youth (aged 10­25 years) with and without an eating disorder during a pro-saccade (looking at a point) and anti-saccade (looking away from a point) eye tracking task. Individuals with an eating disorder made more pro-saccade guesses, had a smaller pupil size and blinked less before a trial started. In individuals with a restrictive type eating disorder (e.g., anorexia nervosa restrictive type), pupil responses may have a relationship with emotional dysregulation (poorly regulated emotional responses). Overall, this study represents an important step towards identifying oculomotor behavior differences in individuals with an eating disorder compared to controls.

Latent Change Trajectories in Mood During Focused CBT Enhanced for Eating Disorders Are Associated With Global Eating Pathology at Posttreatment and Follow-Up Among Individuals With Bulimia Nervosa Spectrum Disorders: A Preliminary Examination.

Bulimia nervosa (BN) is characterized by recurrent loss of control over eating (LOC) and inappropriate compensatory behaviors. Although cognitive-behavioral therapy (CBT) is efficacious for BN, many patients continue to experience symptoms at posttreatment. One potential driver of this low treatment response may be low mood, which maintains BN symptoms through negative reinforcement. Thus, it is important to understand how mood changes over enhanced cognitive-behavioral therapy (CBT-E) and whether these changes are associated with improved treatment outcomes. Participants (N = 56) with BN-spectrum eating disorders (EDs) received 16 sessions of the focused version of CBT-E. The Eating Disorder Examination (EDE) was used to measure ED symptoms (global ED pathology, frequency of binge episodes, and compensatory behaviors) at pre- and posttreatment. Latent growth mixture modeling (LGMM) of affective ratings via digital self-monitoring identified latent growth classes. Kruskal-Wallis H tests examined the effect of trajectory of change in mood on pre- to posttreatment symptom change. LGMM yielded a four-class model that best fit the data representing distinct mood trajectories over the course of treatment: (a) highest baseline mood, linear improving; (b) moderate baseline mood, stable; (c) moderate baseline mood, quadratic worsening; and (d) lowest baseline mood, quadratic improving. Participants who demonstrated worsening mood over treatment (i.e., individuals in the "moderate baseline mood, quadratic worsening" class) had significantly higher EDE global scores at posttreatment and follow-up compared to participants with stable mood across treatment. Change in LOC eating frequency and compensatory behaviors across treatment did not significantly differ by mood class. The main effect of mood class or interaction effect between time and mood class on objective binge episodes, subjective binge episodes, and compensatory behaviors was not significant. There were no significant differences in global ED pathology at either posttreatment or follow-up for any other class comparisons. These results suggest that certain trajectories of change in mood during treatment are particularly associated with change in pre- to posttreatment EDE global score. If replicated, our findings could suggest that future iterations of CBT-E should target mood early in treatment in order to maximize reductions in global eating pathology.

Infant feeding for women with an eating disorder: An interpretative phenomenological analysis.

Mothers with eating disorders can face additional challenges with infant feeding, and there is evidence they are likely to cease breastfeeding earlier than intended. However, there is little research exploring this. The present study used interpretative phenomenological analysis to explore the lived experience of infant feeding for mothers suffering from or recovering from an eating disorder. Semistructured interviews were conducted with six women-five who had breastfed and one who formula-fed. The women experienced two incompatible worlds-motherhood and an eating disorder. Tensions were sometimes resolved by reducing eating disordered behaviour alongside immersion in motherhood. Two participants did not find infant feeding particularly important for their journey into motherhood. Four recounted a positive shift in their relationship to their body through breastfeeding and felt their embodied experience of mothering provided a route out of eating disordered behaviour. However, doubts about their mothering and infant feeding capabilities could be amplified by feeling mistrusted by others and by the relative silence around eating disorders within maternity care services. Respectful dialogue with health care professionals was particularly valued where this occurred. Although long-term outcomes for the participants are unknown, the study suggests women with a history of eating disorders can form successful breastfeeding relationships and may be motivated to engage in collaborative risk assessment. However, they need support in managing emotional challenges. Training around eating disorders for maternity care professionals is likely to be useful for enhancing confidence in engaging mothers proactively to share concerns about eating, weight and body shape.

Experiences of intensive treatment for people with eating disorders: a systematic review and thematic synthesis.

BACKGROUND: Eating disorders are complex difficulties that impact the individual, their supporters and society. Increasing numbers are being admitted to intensive treatment settings (e.g., for inpatient treatment, day-patient treatment or acute medical treatment). The lived experience perspectives of what helps and hinders eating disorder recovery during intensive treatment is an emerging area of interest. This review aims to explore patients' perspectives of what helps and hinders recovery in these contexts. METHODS: A systematic review was conducted to identify studies using qualitative methods to explore patients' experiences of intensive treatment for an eating disorder. Article quality was assessed using the Critical Appraisal Skill Programme (CASP) checklist and thematic synthesis was used to analyse the primary research and develop overarching analytical themes. RESULTS: Thirty articles met inclusion criteria and were included in this review. The methodological quality was mostly good. Thematic synthesis generated six main themes; collaborative care supports recovery; a safe and terrifying environment; negotiating identity; supporting mind and body; the need for specialist support; and the value of close others. The included articles focused predominantly on specialist inpatient care and were from eight different countries. One clear limitation was that ethnicity data were not reported in 22 out of the 30 studies. When ethnicity data were reported, participants predominantly identified as white. CONCLUSIONS: This review identifies that a person-centred, biopsychosocial approach is necessary throughout all stages of eating disorder treatment, with support from a sufficiently resourced and adequately trained multidisciplinary team. Improving physical health remains fundamental to eating disorder recovery, though psychological support is also essential to understand what causes and maintains the eating disorder and to facilitate a shift away from an eating disorder dominated identity. Carers and peers who instil hope and offer empathy and validation are valuable additional sources of support. Future research should explore what works best for whom and why, evaluating patient and carer focused psychological interventions and dietetic support during intensive treatment. Future research should also explore the long-term effects of, at times, coercive and distressing treatment practices and determine how to mitigate against potential iatrogenic harm.

Some people with eating disorders will need intensive treatment (e.g., inpatient treatment, day-patient treatment or acute medical treatment) during the course of their illness. Understanding what helps and hinders eating disorder recovery during intensive treatment is an important part of developing effective interventions. This review summarises research exploring people with eating disorders' perspectives of intensive treatment, with the aim of identifying what helps and hinders eating disorder recovery. We searched in scientific databases for all published qualitative studies that explored people with eating disorders' perspectives of intensive treatment. Thirty studies meet the inclusion criteria of this literature review. The results sections of these studies were analysed by extracting relevant findings relating to eating disorder recovery. We found that a person-centred, holistic approach is necessary throughout all stages of eating disorder treatment, with support from healthcare professionals and carers with specialist knowledge of how to support people with eating disorders. Improving physical health is fundamental to eating disorder recovery. However, psychological support is also essential to help people with eating disorders to understand what causes and maintains the eating disorder and support them to move away from an eating disorder dominated identity. Areas for future research are outlined.

Behavior Change Techniques Within Digital Interventions for the Treatment of Eating Disorders: Systematic Review and Meta-Analysis.

BACKGROUND: Previous systematic reviews of digital eating disorder interventions have demonstrated effectiveness at improving symptoms of eating disorders; however, our understanding of how these interventions work and what contributes to their effectiveness is limited. Understanding the behavior change techniques (BCTs) that are most commonly included within effective interventions may provide valuable information for researchers and developers. Establishing whether these techniques have been informed by theory will identify whether they target those mechanisms of action that have been identified as core to changing eating disorder behaviors. It will also evaluate the importance of a theoretical approach to digital intervention design. OBJECTIVE: This study aims to define the BCTs within digital self-management interventions or minimally guided self-help interventions for adults with eating disorders that have been evaluated within randomized controlled trials. It also assessed which of the digital interventions were grounded in theory and the range of modes of delivery included. METHODS: A literature search identified randomized controlled trials of digital intervention for the treatment of adults with eating disorders with minimal therapist support. Each digital intervention was coded for BCTs using the established BCT Taxonomy v1; for the application of theory using an adapted version of the theory coding scheme (TCS); and for modes of delivery using the Mode of Delivery Ontology. A meta-analysis evaluated the evidence that any individual BCT moderated effect size or that other potential factors such as the application of theory or number of modes of delivery had an effect on eating disorder outcomes. RESULTS: Digital interventions included an average of 14 (SD 2.6; range 9-18) BCTs. Self-monitoring of behavior was included in all effective interventions, with Problem-solving, Information about antecedents, Feedback on behavior, Self-monitoring of outcomes of behavior, and Action planning identified in >75% (13/17) of effective interventions. Social support and Information about health consequences were more evident in effective interventions at follow-up compared with postintervention measurement. The mean number of modes of delivery was 4 (SD 1.6; range 2-7) out of 12 possible modes, with most interventions (15/17, 88%) being web based. Digital interventions that had a higher score on the TCS had a greater effect size than those with a lower TCS score (subgroup differences: χ21=9.7; P=.002; I²=89.7%) within the meta-analysis. No other subgroup analyses had statistically significant results. CONCLUSIONS: There was a high level of consistency in terms of the most common BCTs within effective interventions; however, there was no evidence that any specific BCT contributed to intervention efficacy. The interventions that were more strongly informed by theory demonstrated greater improvements in eating disorder outcomes compared to waitlist or treatment-as-usual controls. These results can be used to inform the development of future digital eating disorder interventions.

Assessing Avoidant/Restrictive Food Intake Disorder (ARFID) Symptoms Using the Nine Item ARFID Screen in >9000 Swedish Adults With and Without Eating Disorders.

OBJECTIVE: The Nine Item ARFID Scale (NIAS) is a widely used measure assessing symptoms of avoidant/restrictive food intake disorder (ARFID). Previous studies suggest that individuals with eating disorders driven by shape/weight concerns also have elevated scores on the NIAS. To further describe NIAS scores among individuals with diverse current and previous eating disorders, we characterized NIAS scores in a large sample of individuals with eating disorders and evaluated overlap in symptoms measured by the NIAS and the Eating Disorder Examination-Questionnaire (EDE-Q) version 6.0. METHOD: Our sample comprised 9148 participants from the Eating Disorders Genetics Initiative Sweden (EDGI-SE), who completed surveys including NIAS and EDE-Q. NIAS scores were calculated and compared by eating disorder diagnostic group using descriptive statistics and linear models. RESULTS: Participants with current anorexia nervosa demonstrated the highest mean NIAS scores and had the greatest proportion (57.0%) of individuals scoring above a clinical cutoff on at least one of the NIAS subscales. Individuals with bulimia nervosa, binge-eating disorder, and other specified feeding or eating disorder also demonstrated elevated NIAS scores compared to individuals with no lifetime history of an eating disorder (ps < 0.05). All subscales of the NIAS showed small to moderate correlations with all subscales of the EDE-Q (rs = 0.26-0.40). DISCUSSION: Our results substantiate that individuals with eating disorders other than ARFID demonstrate elevated scores on the NIAS, suggesting that this tool is inadequate on its own for differentiating ARFID from shape/weight-motivated eating disorders. Further research is needed to inform clinical interventions addressing the co-occurrence of ARFID-related drivers and shape/weight-related motivation for dietary restriction.

Non-Suicidal Self-Injury in Eating and Feeding Disorder Patients: Characteristics and Clinical Implications in a Group of Referred Female Adolescents.

BACKGROUND: Non-suicidal self-injury (NSSI) and Feeding or Eating Disorders (FEDs) often coexist during adolescence with reciprocal influences on their clinical picture. The present study aimed to identify differences and similarities in the clinical presentation of young patients with both conditions compared to those with the two non-comorbid disorders. METHODS: We consecutively recruited forty-five female patients aged between 11 and 18 at our third-level hospital and subdivided them into three groups (NSSI: n = 15; FED: n = 15; NSSI + FED: n = 15). Patients underwent a full clinical assessment. RESULTS: Based on our results, the NSSI + FED group was characterized by higher rates of binging/purging behaviors, greater prevalence of Cyclothymic Disorder, and a more severe clinical presentation compared to the non-comorbid groups. Moreover, higher levels of suicidal ideation were found in the NSSI + FED group. Pharmacological treatment patterns also differed, with SSRI being prescribed more frequently to NSSI + FED patients while mood stabilizers were prescribed more frequently to NSSI ones. A Principal Component Analysis identified four main dimensions: "Body Image" impairment was more pronounced in NSSI + FED patients, indicating negative attitudes towards their own body; "Metacognition" deficits were higher in NSSI than FED. CONCLUSIONS: The present study underscores distinctive clinical features in patients with comorbid NSSI and FED, emphasizing the urgent need for tailored intervention strategies focusing on specific symptom domains.

Stimulant medications in the management of bulimia nervosa and anorexia nervosa in patients with and without comorbid attention deficit hyperactivity disorder: A systematic review.

OBJECTIVE: People with attentional problems are at increased risk of eating disorders. This paper aimed to systematically review and synthesize the existing evidence on stimulant medication in the management of patients with bulimia nervosa (BN) or anorexia nervosa (AN) with or without comorbid attention deficit hyperactivity disorder (ADHD). METHOD: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A protocol for the review was registered with Open Science Framework (OSF) Registry and critical appraisal of the literature was conducted using Joanna Briggs Institute (JBI) Critical Appraisal Tools. RESULTS: Thirteen articles met inclusion criteria including two quasi-experimental studies, one randomized controlled trial, four case series, and six case reports. 26 cases were included from studies and 32 from case series/reports. Only two cases from a single case report had a diagnosis of AN, while the remainder had BN. Stimulants included methylamphetamine, lisdexamfetamine, methylphenidate, dextroamphetamine sulphate and mixed amphetamine salt. In nearly all cases of BN there were reported reductions in eating disorder symptoms. The rates of adverse effects were high and included weight loss, decreased appetite, tachycardia, dry mouth, fatigue, insomnia, restlessness, nausea, bruxism, headache, palpitations, blood pressure changes, irritability, anxiety, depressed mood, and diaphoresis. CONCLUSION: There is currently insufficient evidence to support the use of stimulant medications to treat symptoms of BN or AN. The authors recommend considering screening patients with BN for ADHD.
