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. LEVEL OF EVIDENCE: Level I-Evidence obtained from: systematic reviews and meta-analyses.

Online content on eating disorders: a natural language processing study.

BACKGROUND: Online content can inform the personal risk of developing an eating disorder, and it can influence the time and motivation to seek treatment. Patients routinely seek information online, and access to information is crucial for both prevention and treatment. The primary aim of the current study was to quantify the readability scores of online content on eating disorders using natural language processing algorithms, across two languages: English and Italian. METHODS: Unique terms related to single diagnoses were searched using Google®. The content available on Wikipedia was also assessed. Readability was defined according to the Flesch Readability Ease (FRE) and the Rate Readability Index (RIX). The scientific support of retrieved content and the authoritativeness of sources were measured through standardized variables. RESULTS: In Italian, online content was more likely published by private psychotherapy institutes or by websites that promote diet-advice or weight-loss. In both languages, the most readable content was on Anorexia Nervosa (RIX 4.18, FRE-en 59.6, FRE-it 41.69), Bulimia Nervosa (RIX 3.99, FRE-en 66.27, FRE-it 39.66) or Binge Eating (RIX 4.01, FRE-en 68.10, FRE-it 38.62). English sources consistently had more references than Italian pages (range 35-182, vs 1-163, respectively). and had a higher percentage of citations available in the target language. The content of these references was mainly reflective of peer-reviewed or clinical manuals. CONCLUSION: Attention should be given to developing online content for Muscle Dysmorphia and Orthorexia Nervosa, as well as improving the overall readability of online content on eating disorders, especially for languages other than English.
