Subtyping youngsters with obesity: A theory-based cluster analysis. Appetite 2022; 168:105723. [PMID: 34606939 DOI: 10.1016/j.appet.2021.105723] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 09/15/2021] [Accepted: 09/28/2021] [Indexed: 11/24/2022]
Abstract
Psychological mechanisms play a crucial role in explaining weight gain. Aim of the present study was to identify subtypes in youngsters with obesity in line with these mechanisms. Defining homogeneous clusters within this heterogeneous group provides relevant information for personalized treatments. Data were collected in N = 572 participants (51% boys, aged 7-19) with extreme obesity (%BMI M = 187.8; SD = 30.9) recruited in an inpatient treatment centre. Based on psychological models of overweight/obesity, the Affect Regulation Model, the Reward Deficiency Model and The Dual Pathway Model, cluster variables were selected assessing emotional eating, reward reactivity and regulative capacities. Youngsters reported on emotional eating (DEBQ Emotional Eating) and reward sensitivity (BAS), while parents reported on children's regulative Executive Functions (BRIEF). Characteristics of the different clusters were examined concerning weight variables (pre and post treatment) and variables indexing problematic eating (DEBQ External Eating, Ch-EDE), affect regulation (FEEL-KJ) and depressive symptoms (CDI). Hierarchical cluster analyses supported the presence of three clusters, further evaluated by K-means cluster analyses. The cluster solutions differed according to age and sex (boys 7-13, boys 14-19, girls 7-13, girls 14-19). In all four age and gender subsamples, an "Emotional Eating" cluster displaying a vulnerable profile (high depression, maladaptive emotion regulation, problematic eating) and a "Reward Deficiency" cluster displaying a more resilient profile were detected. In girls 7-13, a "Weak Executive Functioning" indicative of insufficient self-regulative capacities, showed moderate to high emotional problems and problematic eating. In the other subgroups, the "Mean Level Functioning" cluster also showed elevated emotional problems and problematic eating. Given that different clusters can be identified, and given that these clusters have different profiles on emotional problems and problematic eating, subtyping youngsters with severe obesity is indicated, setting the stage for personalized treatments.

Verbiest I, Blechert J, Debeuf T, Verbeken S, Klosowska JC, Michels N, De Henauw S, Braet C. Is there stress eating in children and adolescents? A first validation of the Dutch version of the Salzburg Stress Eating Scale. Appetite 2021; 167:105657. [PMID: 34419515 DOI: 10.1016/j.appet.2021.105657] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 08/17/2021] [Accepted: 08/18/2021] [Indexed: 12/24/2022]
Abstract
The recently developed Salzburg Stress Eating Scale (SSES) is the first to specifically address the relationship of stress experiences and coping failure on the one hand and increases or decreases in food intake on the other hand. The SSES demonstrated good psychometric properties in English and German speaking adult samples. However, it has not been applied to younger age groups, which may differ in their expression and reporting of stress related eating behavior. Therefore, the current study evaluated the psychometric properties and correlates of the SSES in a Dutch speaking community sample of adolescents (study 1; N = 244, 9-18 years, adjusted BMI range = 71-189%, M = 103%) and in an inpatient sample of adolescents with obesity (study 2; N = 100, 9-16 years, adjusted BMI range = 151-310%, M = 194.5%). Factor analysis confirmed the original one factor structure in both studies. Internal consistency was 0.85 in study 1 and 0.90 in study 2 (Cronbach's alpha). In both the obesity and community sample, SSES scores were positively correlated with other eating-related measures (e.g., emotional eating, external eating), and uncorrelated with non-eating-related wellbeing measures (e.g., perceived stress, depressive symptoms). Unexpectedly, however, no association with adjusted BMI was found in the community sample, obesity sample, or combined sample. The scores of the obesity sample were also compared to the community sample in an age and sex-matched subsample of study 1. Against our hypothesis, the obesity sample did not report higher SSES scores than the community sample. The good internal consistency and the evidence for convergent and discriminant validity indicate that the Dutch version of the SSES seems useful in examining this clinically important eating behavior in adolescents. However, validity with regard to stress eating and BMI remains to be further explored.

Emotional Eating After Manipulating Emotion Regulation: A Laboratory Study in Adolescents. BEHAVIOUR CHANGE 2021.

Abstract
Abstract
It is often assumed that emotional eating occurs when an individual is unable to utilise emotion regulation (ER) to cope with stress. In this stress exposure study, we explored whether manipulating participants’ ER strategies (rumination or self-compassion) influenced their stress-related affect and food consumption. Fifty-three adolescents (Mage = 14.72) were included; half of the participants were instructed to use rumination as their ER strategy, and half were instructed to use self-compassion. We could not demonstrate that the ER strategies differently affected stress-related affect. However, we did find that increased Happiness following ER self-compassion predicted reduced High-Fat Sweet food consumption, whereas increased Happiness following ER rumination instead led to greater High-Fat Sweet food consumption. In participants who ruminated, food consumption reduced feelings of Frustration, but not Boredom or Happiness. Post-hoc exploration revealed that only ER self-compassion, not ER rumination, normalised levels of stress-related affect. The results highlight the need for more research into the complex relationship between ER strategies, affect states, and food types in their effect on emotional eating.

Abstract
Background: Overweight and obesity are growing problems, with more attention recently, to the role of stress in the starting and maintaining process of these clinical problems. However, the mechanisms are not yet known and well-understood; and ecological momentary analyses like the daily variations between stress and eating are far less studied. Emotional eating is highly prevalent and is assumed to be an important mechanism, as a maladaptive emotion regulation (ER) strategy, in starting and maintaining the vicious cycle of (pediatric) obesity. Objectives: The present study aims to investigate in youngsters (10 - 17 years) the daily relationship between stress and the trajectories of self-reported eating behavior (desire to eat motives; hunger eating motives and snacking) throughout 1 week; as well as the moderating role of emotion regulation and emotional eating in an average weight population. Methods: Participants were 109 average weighted youngsters between the age of 10 and 17 years (M age = 13.49; SD = 1.64). The youngsters filled in a trait-questionnaire on emotion regulation and emotional eating at home before starting the study, and answered an online diary after school time, during seven consecutive days. Desire to eat motives, hunger eating motives and snacking were assessed daily for seven consecutive days. Results: Using multilevel analyses results revealed that daily stress is significantly associated with trajectories of desire to eat motives and hunger eating motives. No evidence was found for the moderating role of maladaptive ER in these relationships; marginally significant evidence was found for the moderating role of emotional eating in the trajectories of desire to eat and snacking. Discussion: These results stress the importance of looking into the daily relationship between stress and eating behavior parameters, as both are related with change over and within days. More research is needed to draw firm conclusion on the moderating role of ER strategies and emotional eating.

Parent-Reported BIS/BAS Scales for Children: Factor Structure and Measurement Invariance Across Age and Gender. Assessment 2017; 26:1282-1295.

Abstract
The present study examined the factor structure and measurement invariance of the Behavioral Inhibition System/Behavioral Approach System (BIS/BAS) scales parent-report in children and adolescents ( N = 1,444, 58% girls) across age (Group 1, 2-5 years; Group 2, 6-9 years; Group 3, 10-13 years; Group 4, 14-18 years old) and gender. The results consistently underscored a four-factor structure, resembling the original factor structure, with one BIS-factor and three BAS-factors. Multigroup confirmatory factor analysis showed full measurement invariance across gender as well as across Group 1 and 2, and Group 2 and 3. Strong measurement invariance was found across Group 3 and 4, Group 1 and 3, and Group 2 and 4. Configural and metric invariance was found across Group 1 and 4. Hence, mean-level BIS/BAS scores can be compared across gender and age although comparison between preschool children (Group 1) and late secondary school children (Group 4) should be done with caution.
