Abnormal eating behavior in video-recorded meals in anorexia nervosa.

ABSTRACT: Eating behavior during meals in anorexia nervosa (AN) has long been noted to be abnormal, but little research has been done carefully characterizing these behaviors. These eating behaviors have been considered pathological, but are not well understood. The current study sought to quantify ingestive and non-ingestive behaviors during a laboratory lunch meal, compare them to the behaviors of healthy controls (HC), and examine their relationships with caloric intake and anxiety during the meal.A standardized lunch meal was video-recorded for 26 individuals with AN and 10 HC. Duration, frequency, and latency of 16 mealtime behaviors were coded using computer software. Caloric intake, dietary energy density (DEDS), and anxiety were also measured.Nine mealtime behaviors were identified that distinguished AN from HC: staring at food, tearing food, nibbling/picking, dissecting food, napkin use, inappropriate utensil use, hand fidgeting, eating latency, and nibbling/picking latency. Among AN, a subset of these behaviors was related to caloric intake and anxiety.These data demonstrate that the mealtime behaviors of patients with AN and HC differ significantly, and some of these behaviors may be associated with food intake and anxiety. These mealtime behaviors may be important treatment targets to improve eating behavior in individuals with AN.

Project description:ObjectivesRecovery from anorexia nervosa (AN) is difficult to define, and efforts to establish recovery criteria have led to several versions being proposed. Using the perspectives of people with histories of AN and therapists working in the field, we sought to explore the face validity of Khalsa et al (2017) as one of the most recent examples of proposed systematic recovery criteria.DesignWe interviewed 11 health service users (SUs) with histories of AN who had previously received treatment alongside 8 eating disorder therapists (EDTs), exploring their views on the proposed AN recovery criteria.MethodsData from verbal and written interviews were analysed thematically. Separate thematic analyses of SU and EDT interviews highlighted where concerns converged and diverged across participants.ResultsBoth groups saw some merits of having universally recognized recovery criteria, and the multidimensional approach was welcomed, but EDTs were uncomfortable with considering their use in therapy and SUs felt key components were missing around emotional coping and life quality. SUs disliked the prominence of body mass index (BMI) in the criteria, and all struggled with the proposed duration for recovery. Conceptually, the notion of recovery as an endpoint rather than a journey was contested.ConclusionsOur findings indicate disparities between academically derived recovery criteria and lived experiences and indicate perceived challenges in using such criteria in therapeutic settings. Including SUs and EDTs in the development of criteria may improve the likelihood of consolidating AN recovery criteria, but conceptual challenges remain.Practitioner pointsAN recovery is complex, and the use of research-based AN recovery criteria in therapeutic settings could have a detrimental effect on SUs' outcomes. EDTs should be aware of efforts to define AN recovery criteria. EDTs should engage with debates on defining AN recovery and seek to promote participation in such debates to SUs.
