Relationships between eating disorder psychopathology, sexual hormones and sexual behaviours

Sexual self-concept, functioning, and practices of women with binge eating episodes

PURPOSE

Positive sexuality has received little empirical attention in relation to eating disorders. Two tendencies related to sexuality have been identified among women with anorexia nervosa (avoidance) and bulimia nervosa (disinhibition), but it is unclear if they also apply to women with binge eating episodes without compensatory behaviors. This study aimed at (1) exploring the sexual self-concept, functioning, and practices of women with binge eating episodes with or without comorbid restrictive and/or compensatory behaviors, considering past experiences of violence, and (2) verifying the presence of distinct profiles of sexual dispositions among this population.

METHODS

In total, 253 women reporting recurrent episodes of loss of control related to food intake in the past 5 years, completed a web-based questionnaire. Descriptive and correlational analyses were conducted to outline participants' sexual self-concept, functioning, and practices and to examine the relationship between these factors. A two-step cluster analysis was also performed to determine whether participants presented distinct profiles of sexual dispositions.

RESULTS

Participants were generally characterized by a negative sexual self-concept and poor sexual functioning. While a first subgroup of participants displayed a pattern of sexual difficulties and avoidance, a second subgroup had a positive sexual self-concept, better sexual functioning and a wider range of sexual practices. Subgroups did not differ relative to binge eating.

CONCLUSIONS

Sexuality offers a platform for positive embodiment, which can lead to the improvement of body image and mind-body connection and may thus constitute an essential clinical target to improve treatment related to binge eating episodes.

Efficacy of Yougui pill combined with Buzhong Yiqi decoction in alleviating the sexual dysfunction in female rats through modulation of the gut microbiota

CONTEXT

Yougui pill combined with Buzhong Yiqi decoction (YPBYD) is used to relieve sexual dysfunction in clinical practice.

OBJECTIVE

To investigate changes in microbial composition caused by sexual dysfunction and identify dominant bacteria related to YPBYD treatment.

MATERIALS AND METHODS

Female Sprague-Dawley rats were randomly divided into four groups (n = 6): one group underwent Sham operation (Sham group), while three groups underwent ovariectomy (one model and two treatment groups). The ovariectomized (OVX) rats received oestradiol benzoate (250 µg/kg/week) or YPBYD (3.6 mL/d) via oral gavage for 4 weeks. Vaginal smear assay was performed; the serum levels of cyclic adenosine monophosphate (cAMP) and oestradiol (E2) were measured, followed by collection of stool samples for 16S rRNA sequencing.

RESULTS

After YPBYD treatment, the levels of E2 and cAMP in OVX rats significantly increased (E2: from 20.45 ± 1.60 ng/L to 24.38 ± 1.70 ng/L; cAMP: from 261.41 ± 9.21 pg/mL to 373.75 ± 17.37 pg/mL). OVX treatment decreased diversity of gut microbiota and YPBYD treatment restored gut microbiota composition. Compared with Sham group, the abundance of Romboutsia significantly increased, while those of Proteobacteria and Staphylococcus markedly decreased in OVX group (all p < 0.05); meanwhile, the abundance of these microbes showed an opposite trend after YPBYD treatment. These microbiotas were involved in tyrosine and tryptophan biosynthesis and fatty acid metabolism.

DISCUSSION AND CONCLUSIONS

These findings are the first to indicate YPBYD can alleviate female sexual dysfunction by modulating gut microbiota in OVX rats, which will help enhance the understanding on potential mechanism of YPBYD against sexual dysfunction.

Exploring the link between eating disorders and persistent genital arousal disorder/genito-pelvic dysesthesia: first description and a systematic review of the literature

BACKGROUND

Persistent Genital Arousal Disorder/Genito-Pelvic Dysesthesia (PGAD/GPD) characterized by recurrent physiological genital without corresponding psychological arousal is a poorly understood and researched condition. Based on the first two case descriptions of eating disorders directly linked to PGAD/GPD the aim of this paper was to systematically review the literature on possible associations between eating disorders and PGAD/GPD.

METHOD

A systematic literature search on eating disorders and PGAD/GPD was conducted in PubMed, PsycINFO, and Scopus, complemented by Google Scholar. We included case reports, case series, cross-sectional studies and review articles published in peer-reviewed journals written in English or German-language.

RESULTS

The included original papers described a total of 2078 cases with PGAD/GPD symptomatology. Of these, 892 participants fulfilled all five PGAD/GPD core criteria. The aetiology of PGAD/GPD is unknown. Multifactorial genesis of PGAD/GPD is presumed including neurological, pharmacological, hormonal, vascular and psychological causes. A high degree of psychological comorbidity is reported. No study was found that drew a direct link between eating disorders and PGAD/GPD. Although PGAD/GPD symptoms also occur in adolescents, there are no findings in this regard. However, we found a gap in data collection: eating disorders as potential psychiatric comorbidities were systematically recorded in only a few studies.

CONCLUSION

The existing literature have not yet considered a possible link between eating disorders and PGAD/GPD so far. According to the authors' knowledge, this work is the first review to systematically explore the associations. We suspect underreporting of PGAD/GPD cases in eating disorders and particularly during adolescence. We argue that there are several common factors that appear to be important in the etiology, course, and treatment of both disorders (e.g. hormonal dysregulation or sensory sensitivity and avoidance), warranting future research on the possible comorbidity of these disorders.

Attachment insecurity predicts worse outcome in patients with eating disorders treated with enhanced cognitive behavior therapy: A one-year follow-up study

OBJECTIVE

This study aimed to explore the role of attachment insecurity in predicting a worse longitudinal trend of eating disorder (ED) psychopathology and body uneasiness in patients with Anorexia Nervosa (AN) or Bulimia Nervosa (BN) treated with Enhanced Cognitive Behavior Therapy, considering the longitudinal interplay between these dimensions.

METHOD

In total, 185 patients with AN or BN performed the baseline assessment, and 123 were re-evaluated after 1 year of treatment. Participants completed questionnaires evaluating ED psychopathology (Eating Disorders Examination Questionnaire) and body uneasiness (body uneasiness test). For the assessment of adult attachment, the Experiences in Close Relationships-Revised was administered at baseline. Bivariate latent change score analysis within the structural equation modeling framework was performed to investigate the evolution of ED psychopathology and body uneasiness, their longitudinal interplay, and the role of attachment style as an outcome predictor.

RESULTS

After treatment, all psychopathological features showed an overall improvement. Higher baseline levels of body uneasiness predicted a worse course of ED psychopathology. The change in body uneasiness over time depended on changes over time in ED psychopathology, but not vice versa. Insecure attachment predicted a worse longitudinal trend of ED psychopathology, and, through this impairment, it indirectly maintained higher levels of body uneasiness, as confirmed by mediation analyses.

DISCUSSION

The role of attachment insecurity as a predictor of treatment outcome suggests the need for an integration of the cognitive-behavioral conceptualization of EDs with a developmental perspective that considers attachment-related issues.

PUBLIC SIGNIFICANCE STATEMENT

Considering the burden of EDs in terms of public health and the unsatisfactory response to standard treatments, the identification of outcome predictors is of considerable clinical interest. This study demonstrated that attachment insecurity was associated with worse longitudinal trends of ED psychopathology and body uneasiness in patients with AN and BN treated with CBT-E, highlighting the importance of personalizing treatment programs taking into account a developmental perspective on these disorders.

Avoidant Attachment Style Moderates the Recovery of Healthy Sexuality in Women With Anorexia Nervosa Treated With Enhanced Cognitive Behavior Therapy (CBT-E): A 2-Year Follow-Up Study

BACKGROUND

Insecure Attachment style has been associated with interpersonal problems in persons with Anorexia Nervosa (AN), and it might moderate the recovery of healthy sexuality in these subjects.

AIM

The aim of the present 2-year follow-up study was to evaluate the role of insecure attachment style as a moderator of the recovery of healthy sexuality in women with AN.

METHODS

63 Italian women with AN treated with a multidisciplinary approach including Enhanced Cognitive Behavior Therapy were evaluated by means of a clinical interview and self-administered questionnaires. Individual psychotherapy sessions were administered by experienced psychotherapists over the course of at least 40 weeks (median number of sessions = 43, range: 38-50); trained dieticians provided personalized nutritional counselling to facilitate weight recovery. The assessment was performed at baseline (T0) and after 1 (T1) and 2 (T2) years.

OUTCOMES

The administered questionnaires investigated general psychopathology (SCL-90-R), eating disorder-specific psychopathology (EDE-Q), female sexuality (FSFI) and adult attachment style (ECR).

RESULTS

At baseline, avoidant attachment style was associated with all domains of sexual dysfunction. Longitudinal analysis showed a significant decrease in both eating disorder-specific psychopathology and sexual dysfunctions at follow-up evaluations. However, only 45% of remitted subjects also recovered healthy sexuality: these women reported significantly lower avoidance scores than those who only recovered from AN. Moderation analysis indicated that sexual desire did not increase in participants with higher levels of avoidant attachment.

CLINICAL IMPLICATIONS

These novel findings highlighted the importance of the assessment of adult attachment in the clinical setting, for better characterization and treatment of persons suffering from AN.

STRENGTHS & LIMITATIONS

The long follow-up duration, the multidisciplinary nature of the treatment, and the novelty of the topic were major strengths of the study, whereas the limited sample size and the absence of biological data were the main limitations.

CONCLUSION

This study highlighted the crucial role of avoidant attachment in the relationship between AN and sexual dysfunctions, underlining the importance of integrating treatments with attachment-focused interventions.

Cardiometabolic risk is unraveled by color Doppler ultrasound of the clitoral and uterine arteries in women consulting for sexual symptoms

Female sexual dysfunction (FSD) may be a mirror of a poor cardiometabolic state. In a small pilot study enrolling 71 women with FSD, we previously demonstrated that clitoral Pulsatility Index (PI) evaluated by using color Doppler ultrasound (CDU), reflecting vascular resistance, was associated with cardiometabolic risk factors. Data on uterine CDU in this context are lacking. First, to confirm previously reported data on the direct association between clitoral PI and cardiometabolic risk factors on a larger study population of women consulting for sexual symptoms; second, to investigate eventual similar correlations between cardiometabolic risk factors and CDU parameters of the uterine artery. We also ascertained whether uterine artery PI, similarly to what had previously been observed for clitoral artery PI, was directly related to body image uneasiness and psychopathological symptoms, assessed by validated questionnaires. N = 230 women consulting our clinic for sexual symptoms were examined with clitoral CDU and blood sampling and were asked to fill out the Female Sexual Function Index, the Middlesex Hospital Questionnaire (MHQ) and the Body Uneasiness Test (BUT). In a subgroup of women (n = 164), we also performed transvaginal CDU with measurement of uterine artery parameters. At multivariate analysis, we found a direct association between clitoral PI and body mass index (BMI) (p = 0.004), waist circumference (WC) (p = 0.004), triglycerides (p = 0.006), insulin (p = 0.029) and HOMA-IR (p = 0.009). Furthermore, a correlation between obesity and Metabolic Syndrome (MetS) and a higher clitoral PI was observed (p = 0.003 and p = 0.012, respectively). Clitoral PI was also correlated with MHQ-S (p = 0.010), a scale exploring somatized anxiety symptoms, and BUT-B Positive Symptom Distress Index (p = 0.010), a measure of body image concerns. Similarly, when investigating the uterine artery, we were able to demonstrate an association between its PI and BMI (p < 0.0001), WC (p = 0.001), insulin (p = 0.006), glycated haemoglobin (p =  < 0.0001), and HOMA-IR (p = 0.009). Women diagnosed with obesity and MetS showed significantly higher uterine PI values vs. those without obesity or MetS (p = 0.001 and p = 0.004, respectively). Finally, uterine PI was associated with BUT-A Global Severity Index (p < 0.0001) and with several other BUT-A subdomains. Vascular resistance of clitoral and uterine arteries is associated with cardiometabolic risk factors and body image concerns in women consulting for sexual symptoms. If further confirmed in different populations, our data could suggest CDU, a common examination method, as a useful tool for an identification—and possible correction—of cardiometabolic risk factors.

A seven-gene prognostic model related to immune checkpoint PD-1 revealing overall survival in patients with lung adenocarcinoma

BACKGROUND

We aimed to identify the immune checkpoint Programmed cell death 1 (PD-1)-related gene signatures to predict the overall survival of lung adenocarcinoma (LUAD).

METHODS

RNA-seq datasets associated with LUAD as well as clinical information were downloaded from the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) databases. Based on the expression level of PD-1, Kaplan-Meier (K-M) survival analysis was performed to divide samples into PD-1 high- and low- expression groups. Then, differentially expressed genes (DEGs) between high- and low- expression groups were identified. Meanwhile, samples were divided into the high and low immune infiltration groups according to score of immune cell, followed by screening of DEGs between these two groups. Subsequently, DEGs related to both PD-1 expression and immune infiltration was integrated to obtain the overlapping genes. Lasso COX regressions were implemented to construct prognostic signatures. The prognostic model was validated using an independent GEO dataset and TCGA cohorts. In addition, the predictive ability of the seven-gene prognostic model with other molecular biomarkers was compared.

RESULTS

A seven-gene signature (DPT, ITGAD, CLECL1, SYT13, DUSP26, AMPD1, and NELL2) related to PD-1 was developed through Lasso Cox regression. Univariate and multivariate regression analyses indicated that the constructed risk model was an independent prognostic factor. K-M survival analysis indicated that patients in the high risk group had significantly worse prognosis than those in the low risk group. Further, the results of validation analysis showed that this model was reliable and effective.

CONCLUSIONS

The constructed prognostic model can predict overall survival in LUAD patients with great predictive performance, and it may be applied for diagnosis and adjuvant treatment of LUAD in clinical trials.

Physical Activity and Female Sexual Dysfunction: A Lot Helps, But Not Too Much

BACKGROUND

Research on the relationship between physical activity (PA) and female sexual dysfunction (FSD) is lacking.

AIM

To investigate the clinical, psychological, and sexual correlates of PA in women with FSD.

METHODS

A non-selected series of n = 322 pre- and post-menopausal patients consulting for FSD was retrospectively studied. Regular involvement in PA and its frequency (<1 hour/week: sedentary, 1-3 hours/week: active, 4-6 hours/week: very active, >6 hours/week: extremely active) were investigated with a specific question.

OUTCOMES

FSDs, including HSDD (Hypoactive sexual desire disorder) and FGAD (Female genital arousal disorder), were diagnosed according to a structured and clinical interview. Participants underwent a physical examination and a clitoral Doppler ultrasound, and were asked to complete the Female Sexual Function Index, Female Sexual Distress Scale-Revised, Body Uneasiness Test, and Middlesex Hospital Questionnaire.

RESULTS

At multivariate analysis, women engaging in PA (67.4%, n = 217) scored significantly higher in several Female Sexual Function Index domains - including desire, arousal and lubrication - and showed lower sexual distress and lower resistance of clitoral arteries, as compared to sedentary women. A significant, inverse association between PA and HSDD was observed. Mediation analysis demonstrated that the negative association between PA and HSDD was partly mediated by body image concerns (Body Uneasiness Test Global severity index), psychopathological symptoms (Middlesex Hospital Questionnaire total score) and sexual distress (Female Sexual Distress Scale-Revised score). These latter 2 factors also partly mediated the association between PA and a reduced risk of FGAD, whilst a lower BMI was a full mediator in the relationship between PA and FGAD. Finally, extreme PA was associated with significantly worse scores in several psychosexual parameters (i,e, sexual satisfaction and histrionic/hysterical symptoms), even compared to a sedentary lifestyle.

CLINICAL IMPLICATIONS

Women consulting for FSD may gain benefits on desire, arousal, lubrication and sex-related distress from regular PA; however, physicians should remain alert to the downsides of excessive exercise.

STRENGTHS & LIMITATIONS

The main strength lies in the novelty of the findings. The main limitations are the cross-sectional nature, the clinical setting, the small sample size of the different PA groups, and the use of self-reported instruments for the evaluation of PA.

CONCLUSION

In women with FSD, PA was associated with better sexual function and clitoral vascularization, lower sexual distress and reduced odds of HSDD and FGAD; the benefits of PA on sexuality were mediated by both psychological and organic determinants; excessive PA was related with a poor overall sexual function and with a low sexual satisfaction.

Ghrelin as a possible biomarker and maintaining factor in patients with eating disorders reporting childhood traumatic experiences

OBJECTIVE

The recent conceptualization of ghrelin as a stress hormone suggested that its chronic alterations may have a role in maintaining overeating behaviors in subjects with eating disorders (EDs) reporting childhood traumatic experiences. The aim of this study was to investigate the alterations of ghrelin levels in patients with EDs, their associations with early trauma, binge and emotional eating, and possible moderation/mediation models.

METHOD

Sixty-four patients with EDs and 42 healthy controls (HCs) had their plasma ghrelin levels measured and completed questionnaires evaluating general and ED-specific psychopathology, emotional eating, and childhood traumatic experiences.

RESULTS

Participants with anorexia nervosa had higher ghrelin levels than HCs in body mass index (BMI)-adjusted comparisons. Moreover, patients reporting a history of childhood trauma had higher ghrelin levels. Childhood sexual abuse (CSA), BMI, and self-induced vomiting were independent predictors of ghrelin levels. Moderation analyses showed that ghrelin levels were associated with binge and emotional eating only for higher levels of childhood trauma. Elevated ghrelin was a significant mediator for the association of CSA with binge eating.

CONCLUSIONS

These results support the hypothesis that chronic alterations in ghrelin levels following childhood traumatic experiences could represent a neurobiological maintaining factor of pathological overeating behaviors in EDs.

Disordered Eating and Body Dissatisfaction Associated with Sexual Concerns in Undergraduate Women

While research has shown an association between eating disorders and sexual dysfunction, few studies have examined the association between disordered eating and sexuality in non-clinical samples. Here we measured self-reported symptoms of disordered eating, body dissatisfaction, and psychological features characteristic of eating disorders in relation to sexual difficulties among a sample of n = 656 (mean age = 20.59 years) undergraduate women. Disordered eating symptoms were associated with sexual distress, sexual function problems, more cognitive distractions during sexual activity, and poorer sexual self-efficacy. Psychological features characteristic of those with an eating disorder were found to mediate the association between disordered eating and sexual concerns. These findings suggest that eating concerns are associated with sexual difficulties even among women without an eating disorder diagnosis. Further, results highlight the importance of assessing eating disorder symptoms and body dissatisfaction among those seeking treatment for sexual concerns.

Trends in the prevalence and disability-adjusted life years of eating disorders from 1990 to 2017: results from the Global Burden of Disease Study 2017

AIM

Eating disorders have increasingly become a public health concern globally. This study aimed to reveal the burden of eating disorders at the global, regional and national levels using the Global Burden of Disease (GBD) Study 2017 data.

METHODS

We extracted the age-standardised rates (ASRs) of prevalence and disability-adjusted life years (DALYs) and their 95% uncertainty intervals (UIs) of eating disorders, including anorexia nervosa and bulimia nervosa, between 1990 and 2017 from the GBD 2017 data. The estimated annual percentage changes (EAPCs) were calculated to quantify the secular trends of the burden of eating disorders.

RESULTS

The ASRs of prevalence and the DALYs of eating disorders continuously increased worldwide from 1990 to 2017 by an average of 0.65 (95% UI: 0.59-0.71) and 0.66 (95% UI: 0.60-0.72), respectively. The burden of eating disorders was higher in females than in males, but the increment in ASRs was greater in males than in females over time. In 2017, the highest burden of eating disorders was observed in the high sociodemographic index (SDI) regions, especially Australasia (ASR of prevalence = 807.13, 95% UI: 664.20-982.30; ASR of DALYs = 170.74, 95% UI: 113.43-244.14, per 100 000 population), Western Europe and high-income North America. However, the most significant increment of the burden of eating disorders was observed in East Asia (EAPC for prevalence = 2.23, 95% UI: 2.14-2.32; EAPC for DALYs = 2.22, 95% UI: 2.13-2.31), followed by South Asia. An increasing trend in the burden of eating disorders at the national level was observed among most countries or territories. The countries with the top three highest increasing trends were Equatorial Guinea, Bosnia and Herzegovina and China. Positive associations were found between the burden estimates and the SDI levels in almost all geographic regions during the observed 28-year period. We also found that the human development indexes in 2017 were positively correlated with the EAPCs of the ASRs of prevalence (ρ = 0.222, P = 0.002) and DALYs (ρ = 0.208, P = 0.003).

CONCLUSION

The highest burden of eating disorders remains in the high-income western countries, but an increasing trend was observed globally and in all SDI-quintiles, especially in Asian regions that were highly populous. These results could help governments worldwide formulate suitable medical and health policies for the prevention and early intervention of eating disorders.

Sexuality, embodiment and attachment style in anorexia nervosa

PURPOSE

Recent studies hypothesized that sexual dysfunctions represent not just complications of eating disorders (EDs), rather they should be attributed to the core psychopathology of these disorders. Therefore, disorders of the embodiment and insecure attachment may play a role in maintaining an abnormal sexual functioning, given their known relations with core ED features. The aim of the study was to investigate the relationship between sexual dysfunctions and both disorders of the embodiment and attachment style in people with anorexia nervosa (AN).

METHODS

111 adult women with AN and 120 healthy subjects completed the Symptom Checklist-90, Eating Disorder Examination Questionnaire, Identity and Eating Disorders, Attachment Style Questionnaire and the Childhood Trauma Questionnaire-Short Form.

RESULTS

Patients reported worse scores than controls in all areas assessed. In patients, low sexual desire was found to be associated with general and ED-specific psychopathology, and with disorders of embodiment and attachment style. Sexual dysfunctions had no associations with traumatic experiences. Dietary restriction showed an association with low sexual desire through embodiment disorder and Discomfort with Closeness, as confirmed by the serial mediation model.

CONCLUSION

The present study suggests that disorders of embodiment maintained by pathological eating behaviours have a key role in the development of sexual dysfunctions in EDs, through the compromise of intimacy.

LEVEL OF EVIDENCE

Level III, cross-sectional study with comparisons between cases and controls.

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

PURPOSE OF REVIEW

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

RECENT FINDINGS

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

SUMMARY

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

Predictors of Resumption of Menses in Anorexia Nervosa: A 4-Year Longitudinal Study

OBJECTIVE

Amenorrhea is a disabling medical consequence of anorexia nervosa (AN); therefore, resumption of menses (ROM) represents an important goal in the treatment for these patients. The aim of the present study was to evaluate possible clinical, psychopathological, and biological predictors of ROM, including age, body mass index (BMI), AN subtype, childhood abuse, duration of illness, general and eating disorder (ED)-specific psychopathology, and sex hormones.

METHODS

Fifty amenorrheic patients with AN were enrolled. Baseline clinical data and information on childhood abuse were collected. Questionnaires to evaluate general and ED-specific psychopathology were administered, and blood samples were drawn. All patients received treatment as usual and underwent regular follow-up visits for 4 years or until ROM. Time to ROM, BMI at last evaluation, and data regarding diagnostic crossover into bulimia nervosa were collected.

RESULTS

Twenty-nine (58.0%) patients recovered menses. Diagnostic crossover was associated with a higher probability of ROM (odds ratio = 10.3, p = .030). Time-to-event analysis showed that a shorter duration of illness (χ(1) = 11.00, p = .001), binge-eating/purging subtype (χ(1) = 7.01, p = .008), and history of childhood abuse (χ(1) = 4.03, p = .045) were associated with an earlier ROM. Furthermore, higher baseline ED-specific psychopathology was associated with a reduced likelihood for ROM, whereas higher general psychopathology and follicle-stimulating hormone levels predicted an earlier ROM (all, p < .050). Age, BMI, luteinizing hormone, and estrogen hematic levels had no predictive value with respect to ROM.

CONCLUSIONS

The present study provides data in support of an integrated model, emphasizing the importance of duration of illness, childhood abuse, and psychopathological characteristics of amenorrheic patients with AN in predicting ROM.
