Abstract
OBJECTIVES Muscle dysmorphia (MD) is a disorder affecting mainly men and is characterized by significant dissatisfaction with muscles. The idea that MD could represent an addiction has been theoretically discussed, but no empirical data are available. Based on Foster et al. (2015) framework, the Addiction to Body Image Inventory (ABII) was developed. This study aims to validate the ABII and to evaluate its capacity to capture MD severity. METHODS A first community sample of 466 participants was recruited and completed the ABII and questionnaires on MD and body esteem. A second sample of 47 men at risk of MD was recruited mostly in gyms and completed the ABII and questionnaires on MD, eating and psychological symptoms. RESULTS With the community sample, the results showed that the ABII had a valid factorial structure, good internal consistency, and good convergent validity. With the sample of men at risk of MD, the results showed that the ABII had good convergent validity with MD and eating symptoms but not with psychological symptoms. The results of a regression model showed that the ABII explained 12% of the MD variance. CONCLUSIONS This study brings the first measure of addiction to body image and suggests that MD must be understood as a complex phenomenon including eating symptoms and addictive tendencies.

Food addiction and dietary restraint in postpartum women: The role of childhood trauma exposure and postpartum depression. Appetite 2023; 187:106589. [PMID: 37146651 PMCID: PMC11079996 DOI: 10.1016/j.appet.2023.106589] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 04/18/2023] [Accepted: 05/03/2023] [Indexed: 05/07/2023]
Abstract
The early postpartum period is a sensitive time for understanding women's high-risk eating (i.e., eating behavior associated with negative health outcomes) given potential long-term eating behavior implications for infants. Food addiction and dietary restraint are two high-risk eating phenotypes associated with long-term negative health outcomes that have been theoretically linked. Yet, no research has considered how much these constructs overlap during the early postpartum period. The present study sought to characterize these two high-risk eating phenotypes in postpartum women to examine whether these are distinct constructs with specific etiologies and to inform future targets of intervention. Women (N = 277) in the early postpartum period reported on high-risk eating, childhood trauma exposure, depression symptoms, and pre-pregnancy weight. Women's height was measured and pre-pregnancy BMI was calculated. We conducted bivariate correlations and path analysis to characterize the relationship between food addiction and dietary restraint, controlling for pre-pregnancy BMI. Results showed that food addiction and dietary restraint were not significantly associated and that women's childhood trauma exposure and postpartum depression were associated with food addiction but not dietary restraint. Sequential mediation revealed that higher levels of childhood trauma exposure were associated with worse postpartum depression and, in turn, greater food addiction during the early postpartum period. Findings suggest that food addiction and dietary restraint have distinct psychosocial predictors and etiological pathways, which suggests important construct validity differences between the two high-risk eating phenotypes. Interventions seeking to address food addiction in postpartum women and mitigate the impact of this high-risk eating phenotype on the next generation may benefit from treating postpartum depression, especially in women with histories of childhood trauma exposure.

Rios JM, Berg MK, Gearhardt AN. Evaluating Bidirectional Predictive Pathways between Dietary Restraint and Food Addiction in Adolescents. Nutrients 2023; 15:2977. [PMID: 37447303 DOI: 10.3390/nu15132977] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Revised: 06/14/2023] [Accepted: 06/15/2023] [Indexed: 07/15/2023] Open
Abstract
The relationship between food addiction, an important emerging construct of excessive eating pathology, and dietary restraint has yet to be fully understood. Eating disorder models commonly posit that dietary restraint exacerbates loss of control eating (e.g., binge episodes) and may also play a causal role in the development of food addiction. However, dietary restraint as a reaction to consequences of food addiction (e.g., uncontrollable eating or weight gain) represents another plausible pathway. Existing studies indicate that the association between food addiction and dietary restraint may be more significant during adolescence than adulthood, but are limited by cross-sectional study designs. A longitudinal study using an adolescent sample is ideal for investigating potential pathways underlying links between food addiction and dietary restraint. This study examined temporal pathways between food addiction and dietary restraint in a sample of one hundred twenty-seven adolescents (M = 14.8, SD = 1.1) at three timepoints spanning two years. This is the first study to examine longitudinal cross-lagged panel associations between food addiction and dietary restraint. In this adolescent sample, food addiction significantly predicted future dietary restraint (b = 0.25, SE = 0.06, p < 0.001), but dietary restraint did not significantly predict future food addiction (b = 0.06, SE = 0.05, p > 0.05). These findings support the theory that dietary restraint may be a reaction to deleterious effects of food addiction during adolescence.

Disordered Eating Behaviors Related to Food Addiction/Eating Addiction in Inpatients with Obesity and the General Population: The Italian Version of the Addiction-like Eating Behaviors Scale (AEBS-IT).

Abstract
PURPOSE The purpose of this research is to test the psychometric properties and factorial structure of the Addiction-like Eating Behaviors Scale (AEBS) in an Italian sample of adults with severe obesity seeking treatment for weight reduction and the general population, and to examine the measurement invariance of the tool by comparing a clinical and a nonclinical sample. METHODS A confirmatory factor analysis (CFA) was initially conducted to test the factorial structure of the Italian version of the AEBS (AEBS-IT) on a total of 953 participants. Following this, the measurement invariance and psychometric properties of the tool AEBS-IT were assessed on both inpatients with severe obesity (n = 502) and individuals from the general population (n = 451). Reliability and convergent validity analysis were also run. RESULTS CFA revealed a bi-factor structure for the AEBS-IT, which also showed good reliability and positive correlations with food addiction (through the mYFAS2.0 symptom count), binge-eating symptoms, compulsive eating behavior, and dysfunctional eating patterns and the individuals' body mass index (BMI). Moreover, the tool was invariant across populations. CONCLUSION This study provided evidence that the AEBS-IT is a valid and reliable measure of FA in both clinical and nonclinical samples.

Addiction-like Eating in Chinese Adults: An Assessment Tool and Its Associations with Modern Eating-Related Habits. Nutrients 2022; 14:nu14224836. [PMID: 36432524 PMCID: PMC9699218 DOI: 10.3390/nu14224836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 11/01/2022] [Accepted: 11/10/2022] [Indexed: 11/17/2022] Open
Abstract
OBJECTIVES The rapid increase in Chinese obesity rates has aroused research interest in addiction-like eating (AE); however, the unavailability of assessment tools is a major barrier to further investigation. To address the research gap, this study aimed to evaluate the psychometric properties of the Addiction-like Eating Behavior Scale (AEBS) and explore associations between AE and three modern eating-related habits (i.e., ordering delivery food, eating late-night meals and watching mukbang) among Chinese adults. METHODS The STROBE checklist was followed for reporting this cross-sectional study. We conducted a telephone survey with a two-stage cluster random sampling method and acquired a probability sample of 1010 community-dwelling Chinese adults (55.2% female; age: 18-88 years, M = 38.52, SD = 14.53). RESULTS Results confirmed the conceptualized two-factor structure of AEBS with satisfactory model fit, reliability and validity. Chinese adults reported higher levels of AE in the context of low dietary control rather than appetitive drive. These two AE factors showed significant and positive associations with modern eating-related habits. CONCLUSIONS The current study was the first to assess AE among Chinese adults and provided a reliable and valid assessment tool. Our correlational findings can also be utilized for designing interventions for weight management and healthy eating.
