Prepregnancy Body Mass Index shift across gestation: primary evidence of an association with eating disorders

Prevalence and related factors of eating disorders in pregnancy: a systematic review and meta-analysis

PURPOSE

To reveal the prevalence of eating disorders (EDs) and related factors in pregnancy.

METHODS

The search was performed in PubMed, EBSCOhost, Web of Science, Scopus, Google Scholar, and Ovid databases search up to April 3, 2022, using the keywords combination of "(eating disorders OR anorexia nervosa OR bulimia nervosa OR binge eating disorder) AND (pregnancy OR pregnant)". Two researchers independently extracted data from the articles using a standard form. We evaluated the quality of the studies according to the Joanna Briggs Institute assessment tools.

RESULTS

The prevalence of EDs in pregnant women in the 11 studies involving 2,369,520 pregnant women was ranging between 0.5 and 10.6%. The prevalence of EDs in pregnant women was 4.3% (95% confidence interval 2%-9%; I2 = 99.5%). The prevalence of anorexia nervosa and binge eating disorder during pregnancy shows a statistically significant increase compared to pre-pregnancy, and the prevalence of bulimia nervosa during pregnancy decreases. The prevalence of EDs is higher in pregnant women under 30 years of age, secondary school graduates, married, and with normal BMI. Half of the pregnant women with EDs had anxiety and about one-third of pregnant women had depression. Excessive exercise is observed in 0.7% of pregnant women, fasting in 0.3%, laxative or diuretic use in 0.1%, and self-induced vomiting in 0.6%.

CONCLUSIONS

This study is important as it is the first systematic review and meta-analysis to reveal the global prevalence of EDs in pregnant women and related factors. Continuing routine screening tests to detect EDs during pregnancy may contribute to taking special preventive measures for risk groups and protecting mother-child health.

Pregorexia: a systematic review and meta-analysis on the constructs of body image dissatisfaction and eating disturbances by gestational age in the peripartum

PURPOSE

Pregorexia is a phenomenon posited to occur in the peripartum, characterized by an attempt to counter pregnancy's physiological changes in body shape through reduced calorie intake or increased physical activity.

METHODS

In this pre-registered systematic review and meta-analysis, body image dissatisfaction and eating psychopathology in the peripartum according to gestational age were formally assessed. PubMed was searched up to May 2023. Selection criteria were represented by studies on body image concerns or eating psychopathology in the peripartum (up to 1 year after delivery). The population needed to include women from the general population or among patients with a history of (or current) eating disorder. For the meta-analysis, 17 studies were included: 10 for body image dissatisfaction (2625 individuals overall), 7 for eating behaviors (2551 individuals overall). The interplay between body image and the following themes was examined in depth: the adoption of breastfeeding, peripartum depression, sociocultural influences on body image, sexual disturbances, experiencing or reporting an altered food intake.

RESULTS

Progressive dissatisfaction with body image during pregnancy by gestational age was observed, stably elevated for at least 12 months postpartum. Eating psychopathology was observed as elevated only at 12 months in the postpartum, but not during pregnancy.

DISCUSSION

The current work offers normative values of body image satisfaction and eating psychopathology in the peripartum by gestational age. The relevance of current results was discussed, in order to inform both current clinical practice and future public policies.

Perception of the Body Image in Women after Childbirth and the Specific Determinants of Their Eating Behavior: Cross-Sectional Study (Silesia, Poland)

Background: Episodes of loss of control over eating during pregnancy affect up to 36% of women during this period. Many women experience natural concerns about weight gain and body-shape changes during pregnancy and the postpartum period, and food cravings and fluctuations in eating patterns during these periods are physiological phenomena. However, pregnancy and the postpartum period may be an additional determinant of eating disorders. Women who perceive their own bodies as significantly deviating from the presented ideal are more likely to experience anxiety/anxiety related to it and also tend to exhibit abnormal eating behaviors. The perception of one’s body figure also plays an important role in maintaining psychological balance Aim: The aim of this study was to assess the perception of body image by postpartum women. The essence of the study was to see if there were psychomarkers associated with lack of control over eating, food restriction, and emotionally motivated eating in the study population. Material and methods: The study was conducted during the fall and winter of 2021. A total of 288 women participated in the study. The age of the subjects ranged from 21 to 45 years. Results: It was found that 198 women (68.8%) were dissatisfied with their current body weight and figure. Respondents with higher post-pregnancy body mass index showed dissatisfaction with their body shape (49.8%; H = 13.042; p = 0.001). Both body satisfaction and BMI level were significant components of the occurrence of pathological phenomena associated with the TFEQ-13 subscales (p < 0.05). Conclusions: Excessive focus on food restriction as well as lack of control over eating had some association with negative self-perception of body image, mainly in the form of body weight dissatisfaction. Eating behaviors showed an association with BMI level and weight satisfaction after pregnancy.

Eating disorders, pregnancy and the postnatal period: a review of the recent literature

PURPOSE OF REVIEW

Eating disorders (ED) are severe psychiatric disorders that affect women in reproductive age. The purpose of this review is to provide an up-to-date overview of the impact of maternal ED on pregnancy and the postnatal period. The clinical implications for identification and management of maternal ED are also discussed.

RECENT FINDINGS

In the last 2 years, 15 articles focused on the impact of maternal ED in pregnancy and postpartum. Findings from this review indicate that around 15% of pregnant women are likely to have had an ED at some point in their lifetime, and about 5% have an ED in pregnancy. Although ED symptoms tend to decrease during pregnancy, remission is often only temporary with symptoms typically resurfacing in the postnatal period. Women with ED are prone to psychiatric comorbidities such as depression and anxiety during the perinatal period, with up to a third of women with ED reporting postnatal depression in clinical studies and prevalence ranging between 40% and 66% in general population samples. Furthermore, recent findings continue to highlight that current and prior history of maternal ED are associated with a heightened risk of adverse pregnancy and birth outcomes, most notably preterm birth and adverse birth weight outcomes.

SUMMARY

These findings continue to emphasise the clinical importance of early identification and response to maternal ED to mitigate potentially adverse maternal and infant outcomes.

Urinary metabolic variation analysis during pregnancy and application in Gestational Diabetes Mellitus and spontaneous abortion biomarker discovery

Pregnancy is associated with the onset of many adaptation processes that are likely to change over the course of gestation. Understanding normal metabolites’ variation with pregnancy progression is crucial for gaining insights of the key nutrients for normal fetal growth, and for comparative research of pregnancy-related complications. This work presents liquid chromatography-mass spectrum-based urine metabolomics study of 50 health pregnant women at three time points during pregnancy. The influence of maternal physiological factors, including age, BMI, parity and gravity to urine metabolome was explored. Additionally, urine metabolomics was applied for early prediction of two pregnancy complications, gestational diabetes mellitus and spontaneous abortion. Our results suggested that during normal pregnancy progression, pathways of steroid hormone biosynthesis and tyrosine metabolism were significantly regulated. BMI is a factor that should be considered during cross-section analysis. Application analysis discovered potential biomarkers for GDM in the first trimester with AUC of 0.89, and potential biomarkers for SA in the first trimester with AUC of 0.90. In conclusion, our study indicated that urine metabolome could reflect variations during pregnancy progression, and has potential value for pregnancy complications early prediction. The clinical trial number for this study is NCT03246295.
