Byrne ME, Shomaker LB, Brady SM, Kozlosky M, Yanovski JA, Tanofsky-Kraff M. Associations between latent trait negative affect and patterns of food-intake among girls with loss-of-control eating. Int J Eat Disord 2020; 53:618-624. [PMID: 32107799 PMCID: PMC8190819 DOI: 10.1002/eat.23253] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2020] [Revised: 02/13/2020] [Accepted: 02/14/2020] [Indexed: 01/06/2023]
Abstract
OBJECTIVE Momentary negative affect (NA) has been shown to predict eating patterns in the laboratory, yet, more stable mood states have not been studied in relation to eating patterns in the laboratory among youth at high risk for binge-eating disorder and obesity. METHOD One-hundred-eight adolescent girls (14.5 ± 1.7 years) with BMI between the 75th-97th percentile who reported loss-of-control (LOC)-eating completed measures of trait anxiety and depressive symptoms. Food-intake patterns were measured from a laboratory test meal (9,385 kcal). Latent factor analysis of depressive symptoms and trait anxiety was used to compute latent trait NA. Multivariate general linear models predicted total energy, snacks, and macronutrient intake from trait NA, adjusting for age, race, height, lean-mass, and percentage fat-mass. RESULTS Trait NA was significantly positively related to total energy-intake, and, specifically, snacks, sweet snacks, and percentage sweet fats (ps ≤ .03), and negatively related to percentage protein consumed (p = .04). DISCUSSION Expanding on affect theory, trait NA may relate to palatable food-intake among girls with LOC-eating. Further data are needed to determine whether those with LOC-eating and trait NA are at heightened risk for the development of binge-eating disorder and obesity.

Eating Disorders and Obesity: The Challenge for Our Times. Nutrients 2019; 11:nu11051055. [PMID: 31083490 PMCID: PMC6566376 DOI: 10.3390/nu11051055] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Accepted: 05/08/2019] [Indexed: 12/26/2022] Open
Abstract
Public health concerns largely have disregarded the important overlap between eating disorders and obesity. This Special Issue addresses this neglect and points to how progress can be made in preventing and treating both. Thirteen primary research papers, three reviews, and two commentaries comprise this Special Issue. Two commentaries set the scene, noting the need for an integrated approach to prevention and treatment. The empirical papers and reviews fall into four broad areas of research: first, an understanding of the neuroscience of eating behaviours and body weight; second, relationships between disordered eating and obesity risk; third, new and integrated approaches in treatment; and fourth, assessment. Collectively, the papers highlight progress in science, translational research, and future research directions.
