Social support for young people with eating disorders-An integrative review.

Eating disorder treatment should be underpinned by a recovery-oriented approach, be therapeutic, personalised and trauma informed. Within such models of care, social support is an important factor to explore in terms of its influence in supporting hope for recovery, reducing stigma, and mitigating life stressors. Limited research has been conducted to understand the types of social support that are available to young people formally diagnosed with an eating disorder, their feasibility and acceptability and the positive outcomes. This integrative review sought to explore the positive outcomes of social support or social support programs for young people with eating disorders. An integrative review was conducted based on a search of five electronic databases from inception to 31 March 2023. Methodological quality was assessed using the Joanna Briggs Institute Critical Appraisal Tools and findings have been narratively synthesised and presented in accordance with the review's aims and questions. Seven studies (total 429 individuals, range 3-160) published between 2001 and 2023 were included in the final synthesis. Overall social support interventions showed promising preliminary evidence as a feasible and acceptable adjunct to treatment for young people with an eating disorder motivated to change, with some clinical improvements in psychopathology. Social support augmented existing relationships, providing a human element of open dialogue, friendship and a sense of hope for recovery. Despite the small number and heterogeneity of the studies, this review has highlighted some promising preliminary benefits. Future treatment for eating disorders should embrace adjunct modalities that enhance psychosocial recovery for young people with eating disorders.

Functional Connectivity Mechanisms Underlying Symptom Reduction Following Lisdexamfetamine Treatment in Binge-Eating Disorder: A Clinical Trial.

Background: Speculation exists as to whether lisdexamfetamine dimesylate (LDX) acts on the functional connectivity (FC) of brain networks that modulate appetite, reward, or inhibitory control in binge-eating disorder (BED). Better insights into its action may help guide the development of more targeted therapeutics and identify who will benefit most from this medication. Here, we use a comprehensive data-driven approach to investigate the brain FC changes that underlie the therapeutic action of LDX in patients with BED. Methods: Forty-six participants with moderate to severe BED received LDX titrated to 50 or 70 mg for an 8-week period. Twenty age-matched healthy control participants were also recruited. Resting-state functional magnetic resonance imaging was used to probe changes in brain FC pre- and post treatment and correlated with change in clinical measures. Results: Ninety-seven percent of trial completers (n = 31) experienced remission or a reduction to mild BED during the 8-week LDX trial. Widespread neural FC changes occurred, with changes in default mode to limbic, executive control to subcortical, and default mode to executive control networks associated with improvements in clinical outcomes. These connections were not distinct from control participants at pretreatment but were different from control participants following LDX treatment. Pretreatment connectivity did not predict treatment response. Conclusions: FC between networks associated with self-referential processing, executive function, and reward seem to underlie the therapeutic effect of LDX in BED. This suggests that LDX activates change via multiple systems, with most changes in compensatory networks rather than in those characterizing the BED diagnosis.

A three-arm randomised controlled trial of a telehealth intervention targeting improvement in addictive eating for Australian adults (the TRACE program).

There is a substantial research base for addictive eating with development of interventions. The current 3-arm RCT aimed to investigate the efficacy of the TRACE (Targeted Research for Addictive and Compulsive Eating) program to decrease addictive eating symptoms and improve mental health. Participants (18-85 yrs) endorsing ≥3 addictive eating symptoms were randomly allocated to 1) active intervention, 2) passive intervention, or 3) control group. Primary outcome was change in addictive eating symptoms 3-months post-baseline measured by the Yale Food Addiction Scale. Depression, anxiety and stress were also assessed. A total of 175 individuals were randomised. Using Linear Mixed Models, from baseline to 3-months, there was significant improvement in symptom scores in all groups with mean decrease of 4.7 (95% CI: -5.8, -3.6; p < 0.001), 3.8 (95% CI: -5.2, -2.4; p < 0.001) and 1.5 (95% CI: -2.6, -0.4; p = 0.01) respectively. Compared with the control group, participants in the active intervention were five times more likely to achieve a clinically significant change in symptom scores. There was a significant reduction in depression scores in the active and passive intervention groups, but not control group [-2.9 (95% CI: -4.5, -1.3); -2.3 (95% CI: -4.3, -0.3); 0.5 (95% CI: -1.1, 2.1), respectively]; a significant reduction in stress scores within the active group, but not passive intervention or control groups [-1.3 (95% CI: -2.2, -0.5); -1.0 (95% CI: -2.1, 0.1); 0.4 (95% CI: -0.5, 1.2), respectively]; and the reduction in anxiety scores over time was similar for all groups. A dietitian-led telehealth intervention for addictive eating in adults was more effective than a passive or control condition in reducing addictive eating scores from baseline to 6 months.

Epidemiologia dos transtornos alimentares: estado atual e desenvolvimentos futuros / Epidemiology of eating disorders: current status and future developments

Os objetivos do presente trabalho foram: fornecer uma avaliaçäo do progresso da epidemiologia na área de transtornos alimentares, desde estudos sobre incidência e prevalência até os estudos comunitários prospectivos, bem como estudos caso-controle; sintetizar o atual estado da incidência e prevalência dos transtornos alimentares; discutir os estudos epidemiológicos analíticos sobre os transtornos alimentares, enfocando estudos comunitários sobre fatores de risco e nosologia; e apontar as áreas de estudos futuros, especialmente sobre a carga social e econômica e o grau de "conhecimento sobre saúde mental" da populaçäo em geral a respeito das pessoas com transtornos alimentares. Apesar dos problemas para identificar e recrutar um número suficiente de pessoas com anorexia nervosa e os métodos variáveis de recrutamento de casos, os estudos sobre incidência e prevalência dos transtornos alimentares atingiram um consenso e em geral näo corroboram uma incidência ascendente atual, exceto, possivelmente, por um pequeno aumento na anorexia nervosa em mulheres jovens. A aplicaçäo de métodos epidemiológicos analíticos permitiu uma compreensäo melhor dos fatores ambientais e genéticos, em comparaçäo com os sociais e econômicos, quanto ao risco de desenvolvimento de transtornos alimentares, bem como ajudaram no refinamento da nosologia desses transtornos. Futuramente, a epidemiologia analítica terá potencial para responder a questöes-chave sobre a natureza e os determinantes dos transtornos alimentares e para ajudar a decidir como auxiliar os que mais necessitem
