Insufficient physical activity (PA) and excessive stationary behavior (SB) are contributors to pediatric obesity, though antecedents and consequences of these behaviors in this population are relatively unknown. This pilot study examined affect, loss of control eating (LOCE), overeating, and hunger surrounding PA and SB in 17 youth with overweight/obesity. Participants completed a 14-day ecological momentary assessment (EMA) wearing accelerometers. At the momentary level, higher negative affect and lower positive affect predicted SB increases and PA decreases following EMA prompts; higher PA and lower SB also predicted increases in positive affect. Higher LOCE predicted SB increases and PA decreases, while increases in PA and decreases in SB predicted short-term increases in LOCE and overeating. At the individual level, higher SB and lower PA were related to lower positive affect and higher negative affect, LOCE, overeating, and hunger. Findings suggest affect is a relevant antecedent and consequence of PA/SB, and dysregulated eating may acutely impact PA/SB.

Disordered eating behaviors consistently associated with emotion regulation difficulties. However, most studies have focused on affect intensity without considering dynamic affective patterns. We examined these patterns in relation to daily overeating, loss of control eating (LOCE), dietary restraint, and food craving in young adults using ecological momentary assessment (EMA).

Introduction: Few studies have explored the impact of the COVID-19 pandemic on the eating behaviors, dietary quality, and changes in weight of postoperative bariatric surgery patients.

Methods: A cross-sectional survey on eating behaviors and attitudes toward food was emailed or given to patients who had bariatric surgery before March 2020. Patient charts were reviewed for weight measures.

Introduction: Loss-of-control eating (LOCE), inability to refrain from or cease eating, may contribute to significant distress and dysfunction, yet research is lacking specificity on vulnerabilities contributing to LOCE as an independent construct. Preliminary evidence indicates potential roles of distress tolerance, emotion regulation, and affective lability, but the relationship between these variables and LOCE has been under-assessed.

Material And Methods: A sample (N = 3968) consisting of university students completed an assessment of pathological eating and affiliated affective vulnerabilities.

Objective: The link between dysregulated positive affect and binge-eating behavior in youth with obesity is poorly understood. In addition, it is unclear how putative associations differ across developmental periods of rapid biological and emotional change, such as puberty, and in racial and ethnic minority youth, who are more likely to be overweight but are underrepresented in the literature.

Method: This study used a 2-week ecological momentary assessment protocol to examine independent and interactive effects of positive affect intensity/instability, and pubertal stage on two components of binge-eating behavior, loss of control eating (LOCE), and overeating.
