Eat Behav 2024; 53:101871. [PMID: 38518632 PMCID: PMC11144099 DOI: 10.1016/j.eatbeh.2024.101871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 03/09/2024] [Accepted: 03/13/2024] [Indexed: 03/24/2024]
Abstract
Binge eating (BE) is a significant public health concern due to its prevalence and impact on mental and physical health. While research has suggested both negative affect and appetitive traits are associated with BE, few studies have investigated these constructs concurrently. Structural equation modeling (SEM) evaluated relationships between negative affect, reward-related appetitive traits, and BE among 293 adults with overweight or obesity (OW/OB) seeking treatment for BE, overeating, and weight management (m age = 46.6; m body mass index[BMI] = 34.5; 81.2 % female; 20.1 % Latinx, 60.8 % White non-Latinx). BE was related to negative affect (β = 0.53; p < 0.01) and appetitive traits (β = 1.53; p < 0.001). Negative affect and appetitive traits were related to one another (r = 0.42; p < 0.001), and the full model accounted for 77 % of the variance in BE. In an exploratory follow-up analysis, multigroup SEM evaluated the above relationships in models stratified by sex. Exploratory findings demonstrated both negative affect and appetitive traits were related to BE across sex, particularly when examining BE cognitions and behaviors. However, relationships in men depended upon BE assessment tool. These findings highlight that both negative affect and appetitive traits are related to BE, and jointly may represent significant risk and maintenance factors, particularly in adults with OW/OB. Our findings also highlight the importance of future investigation of sex differences in BE and the potential impact of assessment method.

Huryk KM, Drury CR, Loeb KL. Diseases of affluence? A systematic review of the literature on socioeconomic diversity in eating disorders. Eat Behav 2021; 43:101548. [PMID: 34425457 DOI: 10.1016/j.eatbeh.2021.101548] [Citation(s) in RCA: 35] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Revised: 06/01/2021] [Accepted: 08/07/2021] [Indexed: 10/20/2022]
Abstract
The stereotype that eating disorders (ED) primarily present among individuals of higher socioeconomic status (SES) has long persisted in popular and professional perception. This belief has likely contributed to disparities in ED identification and treatment, particularly among those of lower SES backgrounds. The objective of this article was to systematically review the literature investigating socioeconomic diversity in distinct ED diagnoses. A PRISMA search was conducted to identify studies that empirically assessed the association between ED pathology and indicators of SES via PubMed and PsycINFO. This search generated 13,538 articles, of which 62 articles published between 1973 and August 2020 met criteria for inclusion in the review. Included studies were primarily cross-sectional and covered diagnoses of anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED), with quality ratings of poor, fair, and good. Results are examined in the context of studies' sampling methods, operationalization of SES, and statistical analyses. There is no consistent pattern of evidence to suggest a relationship between high SES and ED. Instead, all ED present across a wide range of socioeconomic backgrounds. Limitations included the predominance of cross-sectional study designs and poor to fair quality ratings. Future research should include adequately powered, community-based longitudinal studies that examine how sociocultural factors, including SES, intersect to influence ED risk and treatment outcome. The existing data suggest an urgent need to prioritize affordable and accessible ED treatment.

Abstract
Binge-eating disorder is a common psychiatric disorder affecting ~2% of adults. Binge-eating was initiated in freely-fed, lean, adult, female rats by giving unpredictable, intermittent access to ground, milk chocolate over four weeks. The rats avidly consumed chocolate during 2 hr binge sessions, with compensatory reductions of normal chow intake in these sessions and the days thereafter. Bodyweights of binge-eating rats were normal. The model's predictive validity was explored using nalmefene (0.1-1.0mg/kg), R-baclofen (1.0-10mg/kg) and SB-334867 (3.0-30 mg/kg) (orexin-1 antagonist), which all selectively decreased chocolate bingeing without reducing chow intake. Sibutramine (0.3-5.0mg/kg) non-selectively reduced chocolate and chow consumption. Olanzapine (0.3-3.0mg/kg) was without effect and rolipram (1.0-10mg/kg) abolished all ingestive behaviour. The pro-drug, lisdexamfetamine (LDX; 0.1-1.5mg/kg), dose-dependently reduced chocolate bingeing by ⩽ 71% without significantly decreasing normal chow intake. Its metabolite, D-amphetamine (0.1-1.0mg/kg), dose-dependently and preferentially decreased chocolate bingeing ⩽ 56%. Using selective antagonists to characterize LDX's actions revealed the reduction of chocolate bingeing was partially blocked by prazosin (α1-adrenoceptor; 0.3 and 1.0mg/kg) and possibly by SCH-23390 (D1; 0.1mg/kg). RX821002 (α2-adrenoceptor; 0.1 and 0.3mg/kg) and raclopride (D2; 0.3 and 0.5mg/kg) were without effect. The results indicate that LDX, via its metabolite, d-amphetamine, reduces chocolate bingeing, partly by indirect activation of α1-adrenoceptors and perhaps D1 receptors.

Abstract
BACKGROUND Binge eating (BE) is a disordered eating behavior that has been linked to the development of eating disorders and obesity, with the latter being a condition with higher prevalence rates among some racial minority groups. Although researchers have begun to examine characteristics of BE among racial minority groups, it is unclear how these differ from White populations. OBJECTIVE This article provides an integrative review of published literature within the past decade reporting on the characteristics of BE in minority compared with White racial groups. METHOD Health care computerized databases were searched using key terms. RESULTS Eighteen research studies met the inclusion criteria. More than half of the studies reviewed reported racial differences in some aspect of BE; however, heterogeneity in the definition and measurement of BE limits the ability to compare findings across studies. CONCLUSIONS BE is reported across racial groups. To determine whether meaningful differences in BE exist by race, further studies using the same conceptual and operational definitions of BE are needed.
