Consensus on the assessment of disordered eating in pregnancy: an international Delphi study

Taking Steps Toward a Consensus on Night Eating Syndrome Diagnostic Criteria

BACKGROUND

Night eating syndrome (NES) is included in the Diagnostic and Statistical Manual for Mental Disorders, 5th edition, as an example of "Other Specified Feeding or Eating Disorders" with minimal guidance about how to define and operationalize NES. The literature suggests that research practices vary widely, making it difficult to draw conclusions about the public health burden of, effective interventions for, or policy implications relevant to NES. This Forum article seeks to illustrate the lack of definitional agreement to underscore the need for a consensus about NES diagnostic criteria, and to propose steps toward closing knowledge gaps and achieving consensus.

METHOD

We searched PubMed and PsycINFO titles and abstracts, using "NES" as the search term, for research articles published in English between January 1, 2013 to August 12, 2024 with sample sizes of NES > 10 and ages 18 or older. Eligible articles were coded for NES definitions and assessment method used to diagnose participants with NES and for information about comorbidity of NES and any other eating disorder (ED).

RESULTS

Seventy-three articles met inclusion criteria. Most commonly, NES was diagnosed using a diagnostic criteria set (35/73) or a symptom score threshold (34/73); among the former, only eight studies employed DSM-5 NES criteria. Thirteen studies, varying widely in methodology, examined comorbidity with other EDs, most commonly binge-eating disorder where comorbidity was high.

CONCLUSION

Heterogeneity of definitions and assessment impede progress in the study of NES. We propose strategies for developing a consensus definition and addressing research gaps.

Disordered eating instruments in the pregnancy cohort: a systematic review update

Pregnancy represents a crucial timepoint to screen for disordered eating due to the significant adverse impact on the woman and her infant. There has been an increased interest in disordered eating in pregnancy since the COVID-19 pandemic, which has disproportionately affected the mental health of pregnant women compared to the general population. This systematic review is an update to a previous review aiming to explore current psychometric evidence for any new pregnancy-specific instruments and other measures of disordered eating developed for non-pregnant populations. Systematic searches were conducted in PubMed, ProQuest, PsycInfo, CINAHL, Scopus, MEDLINE, and Embase from April 2019 to February 2024. A total of 20 citations met criteria for inclusion, with most studies of reasonable quality. Fourteen psychometric instruments were identified, including two new pregnancy-specific screening instruments. Overall, preliminary psychometric evidence for the PEBS, DEAPS, and EDE-PV was promising. There is an ongoing need for validation in different samples, study designs, settings, and administration methods are required. Similar to the original review on this topic, we did not find evidence to support a gold standard recommendation.

Management of eating disorders during pregnancy: A survey of Australian dietitians in clinical practice

BACKGROUND

Eating disorders (EDs) are estimated to affect 5.2%-7.5% of pregnant women, equating to 15,800-23,000 births in Australia annually. In pregnancy, an ED increases the risk of complications for both mother and child. Heightened motivation and increased utilisation of healthcare services during pregnancy present an opportunity to identify and commence ED treatment. Dietetic management of EDs differs from nutrition guidelines for pregnancy. This study aimed to assess current practice, confidence and training needs of dietitians to manage EDs in pregnancy.

METHODS

A cross-sectional survey of Australian dietitians with past year exposure to ED and/or antenatal fields was completed using Microsoft Forms between November 2022 and January 2023.

RESULTS

One hundred and seventeen responses were analysed. Confidence was less for assessment of a woman with an active ED in pregnancy than a pregnant woman with a history of an ED, pregnancy or an ED alone (p < 0.001). Greater than 5 years of experience as a dietitian, but without recent exposure to the patient population, was associated with increased confidence (p < 0.01). Almost half provided descriptions of treatments and interventions used to treat a pregnant woman with an ED, some of which conflict with ED or antenatal guidelines. Dietitians were more likely to weigh a person with an ED in pregnancy. Most respondents indicated further training (93%) and guidelines (98%) would be helpful.

CONCLUSION

This is the first investigation into the dietetic management of EDs in pregnancy, and it highlights a need for guidelines and training for dietitians.

Initial psychometric properties of an Arabic version of the disordered eating attitudes in pregnancy scale (A-DEAPS) among Lebanese pregnant women

BACKGROUND

Pregorexia refers to the excessive fear of pregnancy-induced weight gain and the drive to control it through various measures (e.g., extreme restriction of calorie intake, excessive exercising, or diuretics and/or laxatives consumption). The Disordered Eating Attitudes in Pregnancy Scale (DEAPS, Bannatyne et al., in: Disordered eating in pregnancy: the development and validation of a pregnancy-specific screening instrument. Bond University, 2018) is a brief pregnancy-specific instrument developed to screen for antenatal eating disorders. Our study's objective was to examine the reliability and psychometric properties of the Arabic version of this pregnancy-specific scale among Lebanese pregnant women.

METHODS

We conceived and implemented a cross-sectional survey between June and July 2021 (N = 433). The sample was randomly divided in two as per the SPSS data selection option; the first subsample was used to conduct the DEAPS items' exploratory factor analysis (EFA), whereas the second was used for the confirmatory factor analysis (CFA). Within this study, we described multiple indices of goodness-of-fit: the Relative Chi-square (χ²/df), Root Mean Square Error of Approximation (RMSEA), Tucker Lewis Index (TLI), and Comparative Fit Index (CFI).

RESULTS

An EFA was conducted on subsample 1 (N = 207), chosen randomly from the original sample. With the exception of item 8, all other 13 items converged over a two-factor solution [Factor 1 (3 items): Body Image Concerns during Pregnancy, and Factor 2 (10 items): Disordered Eating Attitudes during Pregnancy]. In subsample 2 (N = 226), the CFA results showed that the one-factor model (Factor 2: 10 items), which derived from the EFA conducted on subsample 1, fitted well accordingly to CFI, TLI, and χ²/df values, and fitted modestly according to RMSEA. The CFA estimates obtained for model 1 (original scale of 14 items) and model 2 (according to the two-factor solution obtained from the EFA in subsample 1) fitted less than the third model (Factor 2). The analysis thus suggested retaining only Factor 2 with 10 items in the Arabic version of the scale.

CONCLUSION

Our study was able to provide preliminary evidence that the Arabic 10-item version of the DEAPS seems to be a good and reliable tool for the assessment of disordered eating attitudes among Lebanese pregnant women.

Screening instruments for eating disorders in pregnancy: Current evidence, challenges, and future directions

Pregnancy is a vulnerable period for eating disorder (ED) occurrence and maternal EDs are associated with heightened risk of adverse pregnancy and infant outcomes. This highlights the need to identify pregnant women with past or current EDs in order to offer appropriate support. However, there is a knowledge and practice gap on screening pregnant women for EDs. Clinical guidance is lacking in international treatment guidelines, which is unsurprising given that no validated ED screening tool specifically designed for use in antenatal populations exists. Moreover, data on the effectiveness of general population screening tools for identifying EDs in pregnant women are scarce. This article provides a synthesis of current evidence, treatment guidelines, and data on the diagnostic accuracy for screening for EDs in antenatal samples from three studies with different screening approaches. We outline recommendations for future steps to tackle the knowledge and practice gap on screening for EDs in pregnant women, including next steps for the development of a pregnancy-specific ED screener and the use of general mental health screeners to detect EDs during pregnancy. Up-to-date, the jury is still out as how to best identify current or past EDs in pregnancy. More research is needed to assess the efficacy of using general mental health screeners versus ED-specific screening instruments to detect ED in pregnancy. Additionally, clinicians have to be trained on how to assess and manage EDs during pregnancy. PUBLIC SIGNIFICANCE: Identifying pregnant women with eating disorders (EDs) is a public health concern which can be addressed using multiple approaches, including implementation of general and specific assessments within routine antenatal care, and training of healthcare professionals.

Systematic Review of Literature on Eating Disorders During Pregnancy-Risk and Consequences for Mother and Child

Background: Eating disorders (ED) are a diagnostic category that includes several nosological units such as anorexia nervosa (AN), bulimia nervosa (BN), or binge eating disorder (BED). This category most often concerns women, while the peak incidence falls on the reproductive age. Therefore the issue of ED during pregnancy is an interesting topic. Due to the creation of unrealistic ideal of "desired," slim figure both by the mass media and social media even during and right after gestation, more and more pregnant women introduce behaviours aimed at maintaining the "perfect" appearance. However in some cases it may have serious consequences for the health of both mother and child leading to the creation of the term "pregorexia" by the media to describe this issue. Aim: The aim of this paper was to conduct a systematic review of the literature dealing with eating disorders in pregnant women, with particular emphasis on pregorexia. Method: A systematic review of literature published within the last 5 years (2016-2021) in English or Polish and available through MEDLINE / PubMed, Google Scholar and Cochrane Library databases was conducted based on the previously assumed inclusion and exclusion criteria. Results: Initially, 634 publications were obtained during the review, of which 55 papers were selected in the course of the title analysis. After further evaluation of abstracts, 28 papers were qualified for full text analysis. Ultimately, 10 papers were selected for the final analysis. Conclusions: The issue of ED in pregnant women is a broad topic covering a heterogeneous group of women-both those with a previous history and those with the onset during pregnancy. The occurrence of ED symptoms during this period is associated with a high likelihood of negative consequences for both the mother and the child. The course of pregnancies and deliveries in these patients is more complicated. Therefore, it seems reasonable to develop a multidisciplinary screening strategy and standards of management and supervision over this group of patients.

Development of consensus-based guidelines for outpatient dietetic treatment of eating disorders: A Delphi study

OBJECTIVE

To generate consensus-based guidelines for outpatient dietetic treatment of patients with an eating disorder (ED) using Delphi methodology.

METHOD

A modified Delphi method was used to develop consensus-based guidelines in several categories: referral to a dietitian; essential components of outpatient dietetic treatment; strategies to promote collaboration between dietitians and other healthcare professionals; and skills dietitians should possess if treating patients with an ED. Participants (n = 162) were coded into three panels: ED specialists (n = 79), non-ED specialists (n = 28), and consumers and carers with lived experience of an ED (n = 55). A total of 122 statements were rated across three rounds.

RESULTS

Eighty-one statements reached consensus level (66.4%). A high proportion of endorsed statements were consistent with current guidelines for ED treatment, though some statements for which evidence exists were not endorsed as essential components of dietetic treatment. Compared to consumers and carers, ED specialists were less likely to endorse assessment or involvement by a dietitian as a standard component of treatment, and a number of discrepancies between ED specialists and consumers and carers were observed regarding essential components of dietetic treatment.

DISCUSSION

This study provides consensus-based guidelines in the current absence of clinical practice guidelines for dietetic treatment of EDs. It also highlights the importance of further research into: (a) the effectiveness of different components of dietetic intervention in this population and (b) how dietetic assessment and intervention is best incorporated into outpatient treatment.

Signs and symptoms of disordered eating in pregnancy: a Delphi consensus study

BACKGROUND

This study aimed to establish consensus on the expression and distinction of disordered eating in pregnancy to improve awareness across various health professions and inform the development of a pregnancy-specific assessment instrument.

METHODS

A three-round modified Delphi method was used with two independent panels. International clinicians and researchers with extensive knowledge on and/or clinical experience with eating disorders formed the first panel and were recruited using structured selection criteria. Women who identified with a lived experience of disordered eating in pregnancy formed the second panel and were recruited via expressions of interest from study advertising on pregnancy forums and social media platforms. A systematic search of academic and grey literature produced 200 sources which were used to pre-populate the Round I questionnaire. Additional items were included in Round II based on panel feedback in Round I. Consensus was defined as 75% agreement on an item.

RESULTS

Of the 102 items presented to the 26 professional panel members and 15 consumer panel members, 75 reached consensus across both panels. Both panels clearly identified signs and symptoms of disordered eating in pregnancy and endorsed a number of clinical features practitioners should consider when delineating disordered eating symptomatically from normative pregnancy experiences.

CONCLUSION

A list of signs and symptoms in consensus was identified. The areas of collective agreement may be used to guide clinicians in clinical practice, aid the development of psychometric tools to detect/assess pregnancy-specific disordered eating, in addition to serving as starting point for the development of a core outcome set to measure disordered eating in pregnancy.
