INTRODUÇÃO: A compulsão alimentar (CA) entre mulheres tem sido considerada fator de risco para o diagnóstico de transtornos alimentares mais graves. O objetivo do presente estudo foi investigar a prevalência de CA entre universitárias e a sua associação com IMC (índice de massa corpórea) e idade. MATERIAL E MÉTODO: Foram avaliadas 491 estudantes universitárias, com idade entre 17 e 55 anos, de três áreas de estudo (exatas, saúde e humanas) da Universidade do Vale do Rio dos Sinos (UNISINOS), situada no município de São Leopoldo (RS). Para avaliar a freqüência de CA, utilizou-se o questionário auto-aplicável Escala de Compulsão Alimentar Periódica (ECAP). As medidas de peso e estatura foram auto-informadas. RESULTADOS: A prevalência de CA entre as universitárias estudadas foi de 18,1%. A freqüência de IMC > 25 kg/m² foi de 11,4%, e 75,8% delas apresentavam mais de 20 anos. Observou-se uma associação significativa entre IMC e CA no grupo geral, sendo que 54,5% das universitárias com excesso de peso ou obesidade apresentaram CA (p < 0,001), e a idade não foi associada com a presença de CA. Porém, na área da saúde, as estudantes com idade igual ou menor a 20 anos apresentaram maior freqüência de CA (p < 0,05), e, na área de humanas, o resultado foi inverso (p < 0,05). CONCLUSÃO: O questionário auto-aplicável ECAP revelou elevada prevalência de CA entre mulheres universitárias, mostrando associação com excesso de peso. Investigações futuras são necessárias, com o objetivo de confirmar esses resultados e avaliar a presença de outros transtornos alimentares.

“…Similar observations have been made in many animal models (Harlow, 1932;Tolman, 1964;Reynaud et al, 2015), including freshwater fish (Uematsu and Ogawa, 1975). While it may not be possible to fully model such a complex phenomenon in zebrafish, the ability to regulate feeding based on social context could be a useful indicator of mental function, with abnormal reactions to social context (e.g., reduced feeding in groups) reflecting mental ill-being (Patel and Schlundt, 2001;Brown et al, 2003).…”

Animal models are essential for the discovery of mechanisms and treatments for neuropsychiatric disorders. However, complex mental health disorders such as depression and anxiety are difficult to fully recapitulate in these models. Borrowing from the field of psychiatric genetics, we reiterate the framework of ‘endophenotypes’ – biological or behavioral markers with cellular, molecular or genetic underpinnings – to reduce complex disorders into measurable behaviors that can be compared across organisms. Zebrafish are popular disease models due to the conserved genetic, physiological and anatomical pathways between zebrafish and humans. Adult zebrafish, which display more sophisticated behaviors and cognition, have long been used to model psychiatric disorders. However, larvae (up to 1 month old) are more numerous and also optically transparent, and hence are particularly suited for high-throughput screening and brain-wide neural circuit imaging. A number of behavioral assays have been developed to quantify neuropsychiatric phenomena in larval zebrafish. Here, we will review these assays and the current knowledge regarding the underlying mechanisms of their behavioral readouts. We will also discuss the existing evidence linking larval zebrafish behavior to specific human behavioral traits and how the endophenotype framework can be applied. Importantly, many of the endophenotypes we review do not solely define a diseased state but could manifest as a spectrum across the general population. As such, we make the case for larval zebrafish as a promising model for extending our understanding of population mental health, and for identifying novel therapeutics and interventions with broad impact.

“…Eating-related social comparisons influence both food choices and the amount of food consumed, particularly among restrained eaters (Polivy & Pliner, 2015). Moreover, social situations may trigger disordered eating behavior among individuals with clinical levels of ED pathology (Brown et al, 2003). Although eating-related comparisons are frequently mentioned by clients in clinical ED treatment, most social comparison literature does not directly measure this type of comparison (Fitzsimmons-Craft, Bardone-Cone, & Harney, 2012).…”

Social comparison tendencies are strongly associated with body dissatisfaction and disordered eating. In the current study, we quantitatively examined the structure and predictive value of these constructs during eating disorder recovery. We revised an existing measure of body-, eating-, and exercise-related social comparisons, the Body, Eating, and Exercise Comparison Orientation Measure (BEECOM), to improve psychometric properties. We also assessed the psychometric properties of the shortened Body, Eating, and Exercise Comparison Orientation Measure-Revised (BEECOM-R) in a comparison sample, resulting in an abbreviated measure suitable for recovering, clinical, and non-clinical samples. Finally, we used the revised measure to examine the additive influence of body-, eating-, and exercise-related comparisons on shape and weight dissatisfaction and disordered eating cognitions among 150 women (ages of 18–35 years) in self-identified recovery. Results suggest that body-, eating-, and exercise-related social comparisons all continue to correlate with body dissatisfaction and disordered eating during recovery. A minority of participants reported these comparisons to be helpful during the recovery process. We recommend social comparison as a clinical target for most women seeking support for eating pathology.
