Self-report of eating disorder symptoms among women with and without infertility

Screening, assessment and diagnosis in the eating disorders: findings from a rapid review

BACKGROUND

Limited screening practices, minimal eating disorder training in the healthcare professions, and barriers related to help-seeking contribute to persistent low rates of eating disorder detection, significant unmet treatment need, and appreciable associated disease burden. The current review sought to broadly summarise the literature and identify gaps relating to the screening, assessment, and diagnosis of eating disorders within Western healthcare systems.

METHODS

This paper forms part of a Rapid Review series scoping the evidence base for the field of eating disorders, conducted to inform the Australian National Eating Disorders Research and Translation Strategy 2021-2031, funded and released by the Australian Government. ScienceDirect, PubMed and Ovid/Medline were searched for studies published between 2009 and mid 2021 in English. High-level evidence such as meta-analyses, large population studies and Randomised Control Trials were prioritised through purposive sampling. Data from selected studies relating to Screening, Assessment and Diagnosis of eating disorders were synthesised and are disseminated in the current review.

RESULTS

Eighty seven studies were identified, 38% relating to screening and 62% to assessment and diagnosis. The majority of screening studies were conducted in university student samples, showing high prevalence but only modest improvements in help-seeking in those studies that followed up post-screen. In healthcare settings, clinicians continue to have difficulty identifying eating disorder presentations, particularly Binge Eating Disorder, Other Specified Feeding or Eating Disorders, and sub-threshold eating disorders. This is preceded by inadequate and frequently homogenous screening mechanisms and exacerbated by considerable personal and health-system barriers, including self-stigma and lack of resourcing. While all groups are at risk of delayed or no diagnosis, those at particular risk include LGBTQ+ and gender diverse individuals, individuals living in larger bodies, and males.

CONCLUSIONS

A majority of individuals with eating disorders remain undiagnosed and untreated despite a high prevalence of these conditions and increased advocacy in recent years. Research into improving detection and clinician diagnostic skill is extremely limited. Innovative empirical research is strongly recommended to address significant individual and health-system barriers currently preventing appropriate and timely intervention for many. Limited screening in healthcare settings and low rates of eating disorder training in the healthcare professions are just some of the barriers to help-seeking which may contribute to delayed intervention and diagnosis in the eating disorders. This has significant impacts, prolonging treatment when it is finally received, and increasing healthcare costs for both the individual and the healthcare system. The current review is part of a larger Rapid Review series conducted to inform the development of Australia's National Eating Disorders Research and Translation Strategy 2021-2031. A Rapid Review is designed to comprehensively summarise a body of literature in a short timeframe, often to guide policy-making and address urgent health concerns. The Rapid Review synthesises the current evidence-base and identifies gaps in eating disorder research and care, in order to guide decision making and address urgent health concerns. This paper gives a critical overview of the scientific literature relating to the current state of screening, assessment, and diagnosis of eating disorders within Western healthcare systems that may inform health policy and research in an Australian context. It covers screening initiatives in both general and high-risk populations; personal, clinician and healthcare system challenges relating to help-seeking; and obstacles to accurate and timely clinical diagnosis across the eating disorders.

Prevalence and phenotype of eating disorders in assisted reproduction: a systematic review

Background

Eating disorders (EDs) are common conditions that mainly affect women of reproductive age and have a major impact on fertility. Our systematic review focuses on the prevalence of EDs in patients in the process of assisted reproductive technique (ART) and describes the phenotypes of EDs identified.

Methods

Our systematic review is based on the PRISMA criteria. Articles were collected using the Medline/Pubmed, Web Of Science and Cochrane databases. The articles chosen had to mention the prevalence of ED in infertile patients undergoing ART and be cohort or case–control studies assessing the prevalence of ED during fertility treatment.

Main findings

Fifteen articles were included in this review. The prevalence of active ED varied between 0.13 and 44% depending on the types considered in each study. The main phenotypes described were EDNOS (eating disorder not otherwise specified) and binge eating disorders (BED) occurring in women with a normal body mass index (BMI) and a history of ED. Mainly subthreshold forms with cognitive distortions were described.

Conclusion

This review highlights a 6 times higher prevalence of EDs in infertile patients undergoing fertility treatment compared to regular pregnant women. However, diagnosing these conditions is complex. As a result, it is essential that professionals in contact with this population are alert to symptoms consistent with these conditions in order to refer them to specialized psychiatric care.

Eating disorders are frequent pathologies that primarily affect women of childbearing age. Numerous articles reveal an increased risk for the mother and the child in case of an active disorder during pregnancy.

We conducted a systematic review to determine the prevalence and phenotypes of eating disorders in infertile subjects undergoing fertility treatment.

The results of the fifteen articles included show a prevalence six times higher than in pregnant women in the general population. Subjects with eating disorders have normal body mass indexes. The active forms are mainly characterized by episodes of binge eating disorders or other unspecified forms. Studies also describe incomplete forms characterized by the presence of dysfunctional thoughts around shape and weight without associated compensatory behavior.

Professionals working in the field of reproductive medicine and providing fertility treatment have a major role to play in identifying and referring these subjects at risk to specialized care.

Disordered eating and eating disorders among women seeking fertility treatment: A systematic review

The purpose of this systematic review is to evaluate the prevalence of disordered eating and eating disorders among women seeking fertility treatment.Observational studies were searched in Ovid MEDLINE, Web of Science, Embase, and PsycInfo. Studies published prior to September 2020 when the search was conducted were considered. Inclusion criteria included (1) original and empirical research, (2) published in a peer-reviewed journal, and (3) reported on disordered eating among women seeking fertility treatment in the sample or reported on prevalence of eating disorders among women seeking fertility treatment in the sample. Independent screening of abstracts was conducted by two authors (LH and AH). Ten studies met the inclusion criteria. Sample size, study location, measures, and results for each study in this review were reported.Among women pursuing fertility treatment, rates of current eating disorders ranged from 0.5 to 16.7%, while past eating disorder prevalence rates ranged from 1.4 to 27.5%. Current anorexia nervosa or bulimia nervosa was reported by up to 2% and 10.3% of women, respectively, while history of anorexia nervosa or bulimia nervosa was reported by up to 8.5% and 3.3% of women, respectively. Binge eating disorder or other eating disorders were reported by up to 18.5% and 9.1% of women, respectively. Disordered eating pathology was endorsed by 1.6 to 48% of women seeking fertility treatment. Endorsement of pathological eating attitudes was generally higher among women seeking fertility treatment with current or past eating disorders as compared to community samples, with the exception of dietary restraint. Rates of current and past eating disorders are higher among women seeking fertility treatment than in the general population. Providers treating women with infertility should be cognizant of these prevalence rates and consider screening for eating pathology in their patients as this may contribute to their likelihood of successful conception and/or subsequent pregnancy outcomes.

Female dietary patterns and outcomes of in vitro fertilization (IVF): a systematic literature review

Background

Infertility affects up to 15% of couples. In vitro fertilization (IVF) treatment has modest success rates and some factors associated with infertility and poor treatment outcomes are not modifiable. Several studies have assessed the association between female dietary patterns, a modifiable factor, and IVF outcomes with conflicting results. We performed a systematic literature review to identify female dietary patterns associated with IVF outcomes, evaluate the body of evidence for potential sources of heterogeneity and methodological challenges, and offer suggestions to minimize heterogeneity and bias in future studies.

Methods

We performed systematic literature searches in EMBASE, PubMed, CINAHL, and Cochrane Central Register of Controlled Trials for studies with a publication date up to March 2020. We excluded studies limited to women who were overweight or diagnosed with PCOS. We included studies that evaluated the outcome of pregnancy or live birth. We conducted an initial bias assessment using the SIGN 50 Methodology Checklist 3.

Results

We reviewed 3280 titles and/or titles and abstracts. Seven prospective cohort studies investigating nine dietary patterns fit the inclusion criteria. Higher adherence to the Mediterranean diet, a ‘profertility’ diet, or a Dutch ‘preconception’ diet was associated with pregnancy or live birth after IVF treatment in at least one study. However, causation cannot be assumed. Studies were potentially hindered by methodological challenges (misclassification of the exposure, left truncation, and lack of comprehensive control for confounding) with an associated risk of bias. Studies of the Mediterranean diet were highly heterogenous in findings, study population, and methods. Remaining dietary patterns have only been examined in single and relatively small studies.

Conclusions

Future studies with rigorous and more uniform methodologies are needed to assess the association between female dietary patterns and IVF outcomes. At the clinical level, findings from this review do not support recommending any single dietary pattern for the purpose of improving pregnancy or live birth rates in women undergoing IVF treatment.

Menstrual Disorders Related to Eating Disorders

Eating disorders (ED) are associated with multiple physical complications that strongly affect the physical health of these young and fragile patients and can also cause significant mortality, the highest among psychiatric pathologies. Among the various organic complications, albeit still little known, the gynecological implications, up to infertility, are very widespread. Among adolescent and adult patients, gynecological symptoms can be very widespread and range from menstrual irregularities to amenorrhea, from vaginitis to ovarian polycystosis, up to complications during the gestational phase and postpartum, in addition to the possible consequences on the unborn child. Among the most frequent and significant gynecological disorders in women with ED, there are menstrual irregularities that may occur with oligomenorrhea or even amenorrhea. , Although no longer part of the DSM-5 diagnostic criteria for defining anorexia nervosa (AN), this symptom must be considered a very relevant event in the overall evaluation of young women and adolescents with eating disorders. Functional hypothalamic amenorrhea in ED patients is related to psychological distress, excessive exercise, disordered eating, or a combination of these factors, which results in suppression of the hypothalamic-pituitary-ovarian axis, and consequently, hypoestrogenism. This paper has the objective to summarize the causes and the mechanism underlying menstrual disorders and provide a better understanding of the correlation between the reproductive system and the mechanisms that regulate food intake and eating habits. In addition, early recognition of risk factors for eating disorders for gynecological implications can help put more accurate assessments of patients to prevent potentially fatal complications. The importance of the involvement of specialist gynecologists in the multidisciplinary team that has to follow patients with eating disorders is also discussed.

Hospitalization following eating disorder diagnosis: The buffering effect of marriage and childbearing events

Eating Disorders (ED) are defined as abnormal eating behaviors, stemming from an obsession with food, body weight, or body shape. EDs affect 10 million men and 20 million women in the US, with an estimated 15% lifetime prevalence among women. An ED diagnosis is often accompanied with a host of adverse physical and mental health outcomes, including a heightened risk for suicidality. Given the complex comorbidities associated with EDs, treatment occurs in inpatient and outpatient settings. This study used linked administrative and health records from the Utah Population Database to create a cohort of women n = 4183 and men n = 423 who had a known diagnosis of ED between 1995 and 2015. Cox proportional hazard regression was used to model ED-related hospitalization trajectories, including subsequent risk for suicidality/self-injurious behavior-related hospitalization. To better estimate the risk profiles associated with different health care utilization patterns, models explored how family-related life course events (childbirth, marriage transitions) and sociodemographic characteristics (race, sex, and median income at census-block) modify hospitalization trajectories following initial diagnosis. Results suggested that increased outpatient treatment was associated with reduced risk of initial ED-related hospitalization, but higher risk for subsequent ED-related hospital readmission. In addition, transition to marriage (i.e., getting married) was associated with reduced risk of ED-related and suicidality/self-injurious behavior-related hospitalizations (initial hospitalization and subsequent readmission). Increased number of children was only associated with reduced risk of initial ED-hospitalization, but not readmission. When assessing individuals' risk for ED-related hospitalizations, social and health services researchers should contextualize treatment trajectories within the individual's life experiences, particularly marital transitions, while simultaneously considering sociodemographic characteristics and utilization of outpatient care. Future research should further examine whether marriage represents an important turning point in the health trajectories of individuals with EDs.

•

Childbearing reduces risk of initial eating disorder hospitalization.

•

Marriage reduces risk of eating disorder hospitalization and readmission.

•

Marriage reduces risk of suicidality hospitalization for persons with prior eating disorder.

•

Higher outpatient treatment reduces risk of initial eating disorder hospitalization.

•

Higher outpatient treatment increases risk of eating disorder hospital readmission.

To be thin but not healthy - The body-image dilemma may affect health among female university students in China

An increasing number of young girls have attached great importance to their body-image in China. Body-image dissatisfaction has resulted in increased weight loss behavior. The aim of this study was to investigate the factors that were associated with underweight body-image in female college students. Self-administered questionnaires were completed by 2,023 young female participants from eight Chinese universities. In addition, 160 participants were involved in a qualitative study. The ideal body-image and the factors that influence weight were determined using descriptive and analytical statistics. We found that 1,484 out of 2,023 participants (73.36%) had taken action to lose weight in the past six months. Among these participants, 618 (30.55%, out of 2023) participants were already underweight, and 1,161 (57.39%, out of 2023) would like to be much thinner, which would lead to more underweight individuals. Moreover, non-scientific physical activity and diets were found to lead participants to the underweight subgroup. The participants’ Body Mass Index (BMI), peer advice and western culture influenced the problematic thin-ideal (ideal BMI < 18.5 was considered as the problematic thin-ideal) (P<0.05). Together, western influences leading to the “problematic thin-ideal” and “unhealthy weight-control behavior” have brought about an increased prevalence of desired underweight body-image among female college students in China, which might be harmful for their health.

Stress has a direct and indirect effect on eating pathology in infertile women: avoidant coping style as a mediator

Patient-perceived stress and avoidance-oriented coping strategies are mental health risk factors well documented within the infertility literature. Relatedly, these factors are associated with maladaptive eating behaviours known to influence reproductive functioning. This study aims to investigate the interconnection between perceived stress, avoidant coping style and eating pathology in infertile women, and to determine whether avoidant coping style mediates the relationship between stress and eating pathology. A multicentre cross-sectional study of 416 women (aged 20-47 years) was completed. Women were assessed on the Eating Disorder Examination Questionnaire, the Perceived Stress Scale and the Brief COPE. Correlational matrices, principal components analysis and structural equation modelling were used to develop a measurement model to test the avoidant coping style mediation hypothesis. Results showed that perceived stress had a direct effect on maladaptive eating behaviours [β = 0.21; 95% confidence interval (CI) 0.065-0.346; P = 0.005]. Furthermore, a statistically significant indirect effect between perceived stress and maladaptive eating via avoidant coping style was also observed (β = 0.14; 95% CI = 0.017-0.267; P = 0.018), indicating partial mediation. These findings highlight that both perceived stress and avoidant coping style are important psychotherapy targets to consider in infertile women presenting with eating pathology.

Variation in reproductive outcomes of women with histories of bulimia nervosa, anorexia nervosa, or eating disorder not otherwise specified relative to the general population and closest-aged sisters

OBJECTIVE

This study seeks to examine the long-term reproductive consequences of eating disorders (ED), to assess variation in reproductive outcomes by ED type, and to examine reproductive differences between women with previous ED diagnosis and their discordant sisters.

METHOD

Using a sample of women with previous ED diagnosis generated by the Utah Population Database, this study compares the fecundity (parity) and age at first birth of women by ED subtype (bulimia nervosa [BN], anorexia nervosa [AN], and ED not otherwise specified [EDNOS]) (n = 1,579). We also employed general population match case-control, and discordant sibling pair analyses, to estimate the magnitude of association between EDs and reproductive outcomes.

RESULTS

Women previously diagnosed with AN or EDNOS experienced delayed first birth (HRR = 0.33, HRR = 0.34, respectively) and lower parity (IRR = 0.19, IRR = 0.22, respectively) relative to BN (p < .05), the general population (p < .05), and closest-aged sisters (p < .05). Women previously diagnosed with BN experienced more moderate reductions and delays to their reproduction, and had similar reproductive outcomes as their discordant sisters.

DISCUSSION

Clinicians should consider ED type and family fertility histories when addressing the long-term reproductive health needs of women with prior AN, BN, or EDNOS diagnosis. Women previously diagnosed with AN or EDNOS likely experience the greatest reductions and delays in reproduction across their lifespan. Reproductive health screenings may be especially critical for the wellbeing of women with a history of AN or EDNOS.

Obstetric and gynecologic problems associated with eating disorders

OBJECTIVE

This article summarizes the literature on obstetric and gynecologic complications associated with eating disorders.

METHOD

We performed a comprehensive search of the current literature on obstetric and gynecologic complications associated with eating disorders using PubMed. More recent randomized-controlled trials and larger data sets received priority. We also chose those that we felt would be the most relevant to providers.

RESULTS

Common obstetric and gynecologic complications for women with eating disorders include infertility, unplanned pregnancy, miscarriage, poor nutrition during pregnancy, having a baby with small head circumference, postpartum depression and anxiety, sexual dysfunction and complications in the treatment for gynecologic cancers. There are also unique associations by eating disorder diagnosis, such as earlier cessation of breastfeeding in anorexia nervosa; increased polycystic ovarian syndrome in bulimia nervosa; and complications of obesity as a result of binge eating disorder.

DISCUSSION

We focus on possible biological and psychosocial factors underpinning risk for poor obstetric and gynecological outcomes in eating disorders. Understanding these factors may improve both our understanding of the reproductive needs of women with eating disorders and their medical outcomes. We also highlight the importance of building multidisciplinary teams to provide comprehensive care to women with eating disorders during the reproductive years.

The Deep Correlation between Energy Metabolism and Reproduction: A View on the Effects of Nutrition for Women Fertility

In female mammals, mechanisms have been developed, throughout evolution, to integrate environmental, nutritional and hormonal cues in order to guarantee reproduction in favorable energetic conditions and to inhibit it in case of food scarcity. This metabolic strategy could be an advantage in nutritionally poor environments, but nowadays is affecting women's health. The unlimited availability of nutrients, in association with reduced energy expenditure, leads to alterations in many metabolic pathways and to impairments in the finely tuned inter-relation between energy metabolism and reproduction, thereby affecting female fertility. Many energetic states could influence female reproductive health being under- and over-weight, obesity and strenuous physical activity are all conditions that alter the profiles of specific hormones, such as insulin and adipokines, thus impairing women fertility. Furthermore, specific classes of nutrients might affect female fertility by acting on particular signaling pathways. Dietary fatty acids, carbohydrates, proteins and food-associated components (such as endocrine disruptors) have per se physiological activities and their unbalanced intake, both in quantitative and qualitative terms, might impair metabolic homeostasis and fertility in premenopausal women. Even though we are far from identifying a "fertility diet", lifestyle and dietary interventions might represent a promising and invaluable strategy to manage infertility in premenopausal women.
