Disordered eating measures validated in pregnancy samples: a systematic review

Furthering development of the Eating Disorder Examination-Pregnancy Version (EDE-PV): Exploratory factor analysis and psychometric performance among a community sample of pregnant individuals with body mass index ≥ 25

Psychometrically sound measures of disordered eating during pregnancy are needed, particularly for pregnant individuals with body mass index (BMI) ≥ 25, who are at high risk for disordered eating attitudes/behaviors. We previously adapted the Eating Disorder Examination (EDE) for use among pregnant individuals with BMI ≥ 25. This study examined the factor structure of the EDE-Pregnancy Version (EDE-PV) in a community sample of pregnant individuals with BMI ≥ 25. The EDE-PV was administered to 257 pregnant individuals with pre-pregnancy BMI ≥ 25 between 12 and 20 weeks gestation. The EDE-PV factor structure was determined using an exploratory factor analysis with oblique geomin rotation, internal consistency coefficients were calculated, and convergent and discriminant validity of the EDE-PV factors were assessed. An 11-item, two-factor solution produced an acceptable model fit. The subscales did not replicate those of the EDE and were interpreted as Pregnancy Eating and Weight Change Concerns and Pregnancy Shape and Weight Concerns (αs=.67 and .85; ωs=.70 and .85, respectively). These subscales showed small-to-moderate, positive correlations with weight and psychosocial distress measures and differentiated between participants with and without lifetime histories of any eating disorder diagnosis, demonstrating adequate convergent and discriminant validity. The results indicate that the EDE-PV can more reliably identify factors associated with disordered eating attitudes/behaviors among pregnant individuals with BMI ≥ 25 compared to the EDE and support our call for the development and use of new and/or adapted measures to appropriately assess disordered eating during pregnancy.

The Unique and Moderating Role of Social and Self-Evaluative Factors on Perinatal Eating Disorder and Depression Symptoms

Pregnancy and postpartum represent a critical transition period for changes in eating disorder (ED) symptoms and depression. Past research has established a relationship between ED and depressive symptoms during pregnancy. However, changes in depression and ED symptom across stages of pregnancy and postpartum, and factors that influence this relationship, remain understudied. Social factors and self-evaluative factors may be important given rapidly changing social pressures and expectations during this transitional time. The current study (N = 454 pregnant women) examined (1) differences in ED and depressive symptoms across pregnancy and postpartum and (2) whether social factors (social appearance anxiety; social support) and self-evaluative factors (maladaptive perfectionism; self-compassion) moderate the relationship between depression and ED symptoms cross-sectionally and prospectively. Study aims, hypotheses, and data analysis were preregistered on the Open Science Foundation (osf.io). This study did not identify differences in ED or depression symptoms across women at different stages of pregnancy; however, depression symptoms significantly improved within individuals from pregnancy to postpartum. ED symptoms and all social and self-evaluative factors were uniquely associated with depression during pregnancy. ED symptoms, maladaptive perfectionism, social appearance anxiety, and self-compassion during pregnancy significantly predicted postpartum depression, when accounting for prenatal depression. During pregnancy, but not postpartum, when social support and self-compassion were low, and when maladaptive perfectionism was high, there was a stronger relationship between ED and depression symptoms. ED symptoms and social and self-evaluative factors could be targeted in routine medical care and stepped-care interventions to improve maternal mental healthcare and prevent postpartum depression.

Disordered eating during pregnancy among individuals participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC)

BACKGROUND

Food insecurity is associated with adverse psychosocial and health consequences in pregnancy. In non-pregnant populations, evidence suggests that food insecurity is linked to eating pathology, independent of depression or anxiety. Food assistance programs intended to reduce food insecurity, such as the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), may unintentionally contribute to eating pathology through a "feast-or-famine" cycle (i.e., cyclical periods of food deprivation and food access over the benefit month). Thus, the present study examined associations between WIC participation and disordered eating in pregnancy, covarying for depressive symptoms.

METHODS

The present study is a secondary analysis of the Pittsburgh Girls Study (PGS), a 21-year prospective longitudinal study that over-sampled households in low resourced neighborhoods. The present analysis included a subset of pregnant PGS participants (N = 210; 13-25 years of age) who reported on WIC participation, and disordered eating and depressive symptoms on validated measures.

RESULTS

Negative binomial regression models covarying for participant's age at conception and gestational age at assessment found that WIC participation was associated with higher scores on overall eating pathology as well as dieting and oral control subscales, but not bulimic or food preoccupation subscales, or a binge-eating item. Patterns of findings did not change when depressive symptom severity was included in models.

DISCUSSION

WIC participation was associated with eating pathology during pregnancy. Future research should clarify directional relationships among food insecurity, food assistance, and eating behavior in pregnancy to promote health equity.

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.

Social comparison, disordered eating, and body dissatisfaction among postpartum women

The postpartum period is a window of vulnerability for disordered eating. Postpartum women experience pressures to "bounce back" to their pre-pregnancy weight which may lead to social comparisons, however it is unknown what postpartum women compare (e.g., body, eating), and to whom they compare themselves (e.g., celebrities, peers). This study evaluated links between different types (what is compared) and sources (to whom do they compare) of social comparison that postpartum women engage in. Included was self-oriented comparison, a novel construct conceptualized as comparisons of one's current postpartum appearance to one's pre-pregnancy appearance. A total of 306 postpartum women who gave birth in the past year and 153 control women who had never been pregnant completed an online survey. Results demonstrated postpartum women engaged in more frequent self-oriented comparison than controls. Postpartum women compared their bodies more frequently to their pre-pregnant selves, than to other sources. Although all types and sources of comparison were positively correlated with each disordered eating construct, eating comparison and self-oriented body comparison emerged as the dominant types and sources of comparison explaining unique variance in a range of disordered eating. Results suggest social comparison factors may be critical in understanding postpartum disordered eating risk.

Prevention of eating disorders: 2021 in review

This review of 19 prevention-related publications in Eating Disorders during 2021 is framed by four models: (1) Mental Health Intervention Spectrum: health promotion → types of prevention → case identification/referral → treatment; (2) the prevention cycle: rationale and theory, shaped by critical reviews → clarifying risk and protective factors → program innovation and feasibility studies → efficacy and effectiveness research → program dissemination; (3) links between disordered eating (DE) and eating disorders (EDs); and (4) Kraemer and Jacobi's criteria for variable, causal risk factors (RFs). Twelve articles demonstrated the strengths and limitations of cross-sectional investigations of RFs for DE and EDs: five explored the role of trauma in activating genetic and psychological RFs (e.g., anxiety and experiential avoidance), while five suggest other variables meriting further evaluation: ergogenic supplement use, "feeling fat," internalized weight bias, food insecurity, and compulsive exercising. One article presents a pilot program that reduced risk factors in a high-risk group: professional ballerinas. Implications of the absence of efficacy, effectiveness, dissemination, and advocacy studies, along with the need to develop tailored programs for various high-risk groups, are discussed.

Development and validation across trimester of the Prenatal Eating Behaviors Screening tool

Rapid screening tools are useful for identifying at-risk patients and referring them for further assessment and treatment, but none exist that consider the unique medical needs of pregnant women with eating disorders (EDs). There is a need for a rapid, sensitive, and specific screening tool that can be used to identify a potential ED in pregnancy. We started with a set of 25 questions, developed from our qualitative work along with other ED screening tools, and tested on a development (n = 190) and validation sample (n = 167). Statistical analysis included factor analysis and logistic regressions with ROC curves. Development and validation samples were combined for trimester analysis (n = 357). Refining the tool to 12 items demonstrated strong internal reliability (development alpha = 0.95, validation alpha = 0.91). With correlated errors, questions demonstrated acceptable CFA fit (development: GFI: 0.91, RMSEA: 0.10, NNFI: 0.95; validation: GFI: 0.85, RMSEA: 0.14, NNFI: 0.86). Similar fits were seen by trimester: first trimester n = 127, GFI: 0.89, RMSEA: 0.12, NNFI: 0.94; second trimester n = 150, GFI: 0.83, RMSEA: 0.14, NNFI: 0.88; third trimester n = 80, GFI: 0.99, NNFI: 0.99. Validation against current ED diagnosis demonstrated acceptable sensitivity and specificity using a cutoff of 39 (development sensitivity = 80.7%, specificity = 79.7%, OR = 16.42, 95% CI: 7.51, 35.88; validation sensitivity = 69.2%, specificity = 86.5%, OR: 17.43, 95% CI: 6.46, 47.01). Findings suggest the PEBS tool can reliably and sensitively detect EDs across pregnancy trimesters with 12 questions. A further implication of this work is to reduce health and mental health treatment disparities through this standard and rapid screening measure to ensure early identification and treatment.

Differential Effects of Intuitive and Disordered Eating on Physical and Psychological Outcomes for Women with Young Children

OBJECTIVES

Pressure to lose weight can increase the risk of developing disordered eating behaviours, negative body image and depressive symptomatology. Eating intuitively may counteract these negative outcomes. This research examined the unique relationship between intuitive eating and disordered eating on body mass index (BMI), body image and depressive symptoms for women of young children.

METHODS

A survey of women with a child aged between six and 48 months, included the Intuitive Eating Scale, Eating Attitudes Test-26, Body Shape Questionnaire and Edinburgh Postnatal Depression Scale. Multivariate analysis of variance (MANOVA) was conducted as an omnibus test to estimate the effect of intuitive and disordered eating on BMI, negative body image and depressive symptoms.

RESULTS

Of the 419 sample (M age = 32.06), 32% were classified with disordered and 32% with intuitive eating. MANOVA and regression analysis found disordered eating positively associated with depressive symptoms, (β = 0.303) and negative body image (β = 0.318). Intuitive eating was associated with lower depressive symptoms (β =  - 0.183) and negative body image (β =  - 0.615). Disordered eating (β =  - 0.194) and intuitive eating (β =  - 0.586) both contributed to lower BMI, with the association stronger for intuitive eating.

CONCLUSION

The early parenting period involves a high risk for developing disordered eating behaviours. Eating patterns are modifiable factors, illustrating the potential for positive and preventive health outcomes through adopting intuitive eating behaviours. There is an opportunity for healthcare professionals to promote physical and psychological health including for women in the early parenting period.

Predicting the change in perinatal disordered eating symptoms: An examination of psychosocial factors

Disordered eating symptoms remain a largely unidentified and unsupported area in perinatal healthcare, particularly as they pertain to women without diagnosed eating disorders. In an Australian prospective cohort study, women aged 18-48, completed questionnaires between: 18-24 weeks gestation (n = 249, T1), 30-32 weeks gestation (n = 151, T2) and 8-10 weeks postpartum (n = 124, T3), measuring disordered eating symptoms, psychosocial factors (attitudes to pregnancy or motherhood, self-compassion, relationship satisfaction and perinatal social support) and mental health factors (depressive or anxiety symptoms). Multilevel linear models examined predictive associations between psychosocial factors at T1 and the change in disordered eating symptoms from T1 to T2 and from T1 to T3, in addition to the moderating effects of pre-pregnancy BMI and pregnancy depressive or anxiety symptoms. Whilst restraint and shape concerns decreased from T1 to T2, restraint, shape and weight concerns increased from T1 to T3. Psychosocial factors at T1 were able to predict the change in some disordered eating symptoms. Moreover, when pre-pregnancy BMI or pregnancy depressive or anxiety symptoms were elevated, the impact of psychosocial factors on disordered eating increased. The findings of this study provide a more complex understanding of disordered eating across the perinatal period, with implications for future interventions and research design.
