Introdu??o: A perturba??o de ingest?o alimentar ? um problema de sa?de p?blica com efeitos f?sicos e psicol?gicos, ao longo da vida. Estudos nacionais e internacionais t?m explorado a associa??o dos sintomas desta perturba??o com algumas vari?veis, mas importa continuar a explorar a contribui??o de outros correlatos. ? nosso objetivo central estudar a associa??o e papel preditivo das experi?ncias traum?ticas (?reas emocional, f?sica e sexual), impulsividade e suicidabilidade com/para os sintomas de ingest?o alimentar compulsiva. Metodologia: 421 sujeitos (estudantes universit?rios e pessoas da popula??o geral) (sexo feminino, n = 300; 71,3%) preencheram a Traumatic Events Checklist, a Binge Eating Scale/Lista de H?bitos Alimentares (avalia sintomas de ingest?o alimentar compulsiva/IAC), a Escala de impulsividade de Barratt e a Escala de suicidabilidade. Resultados: Os valores encontrados de preval?ncia pontual de IAC foram semelhantes aos de estudos nacionais recentes, com a gravidade grave a ser de 2,6% na amostra total 3,3% nas mulheres e 0,8% nos homens. Em ambos os sexos, a pontua??o total de suicidabilidade e o ?ndice de massa corporal (IMC) associaram-se ? pontua??o total de IAC. Apenas nas mulheres esta pontua??o se associou ? pontua??o total de trauma sexual e familiar e ao total de experi?ncias traum?ticas. Se nos homens a pontua??o total de suicidabilidade se associou ? pontua??o total de trauma familiar e ao total de experi?ncias traum?ticas, nas mulheres aquela ainda se associou ? pontua??o total de trauma sexual. Nos homens, a pontua??o total de IAC associou-se ao fator de 1? ordem/BIS impulsividade atencional (e respetivos fatores de 2? ordem, aten??o psicol?gica e instabilidade cognitiva) e, nas mulheres, a todos os fatores de 1? ordem (impulsividade atencional, motor e n?o-planeamento) e todos os fatores de 2? ordem (aten??o psicol?gica, instabilidade cognitiva, motor, autocontrolo e complexidade cognitiva), ? exce??o da perseveran?a. Nas mulheres, a impulsividade atencional mostrou-se particularmente associada ? pontua??o total de trauma sexual e familiar e total de experi?ncias traum?ticas. Na subamostra feminina, o IMC, a pontua??o total de suicidabilidade e a impulsividade atencional foram os preditores da pontua??o total de IAC. Discuss?o: Fica saliente, devendo isto mesmo ser considerado em interven??es futuras, sobretudo na subamostra feminina, o papel preditor, do IMC, da pontua??o total de suicidabilidade e da impulsividade atencional, para a ocorr?ncia de sintomas de IAC, com a ocorr?ncia de experi?ncias traum?ticas (enquanto correlato mais distal) a revelar associa??es significativas com aqueles sintomas, mas n?o os predizendo. / Introduction: Binge eating disorder is a public health problem with physical and psychological effects, throughout life. National and international studies have explored the association between this disorder symptoms with some variables, but it is important to continue exploring the contribution of other variables. The main aim of this study is to explore the association and the predictive role of traumatic experiences (emotional, physical and sexual areas), impulsivity and suicidibility with/to binge eating symptoms. Methods: 421 subjects (college students and people from the general population) were assessed (female, n = 300, 71, 3%) completed the Traumatic Events Checklist, the Binge Eating Scale (BES; assesses binge eating symptoms), the Barratt Impulsiveness Scale and the Suicidibility Scale. Results: Regarding the punctual prevalence of binge eating symptoms, according to the BES, the values found were similar to those from recent national studies, having found a severe severity of 2,6% in the total sample, 3,3% in women and 0,8% in men. In both genders, the total score of suicidability and the body mass index (BMI) associated with the total binge eating (BE) score. Only in women this score was correlated with the total score of sexual and family trauma and the total score of traumatic events. If in men the total suicidability score associated with the total score of family trauma and the total score of traumatic events, in women that score was also associated with the total score of sexual trauma. In men, the total score of BE was associated to the 1st order factor attentional impulsivity (and respective 2nd order factors, psychological attention and cognitive instability) and, in women, to all the 1st order factors (attentional impulsivity, motor and non-planning) and all the 2nd order factors (psychological attention, cognitive instability, motor, selfcontrol and cognitive complexity), with the exception of perseverance. In women, attentional impulsivity was particularly associated with the total score of sexual and family trauma and the total of traumatic experiences. In the women subsample, the BMI, the total scores of suicidability and attentional impulsivity were the predictors of BE total score. Discussion: It is salient, and of importance in future interventions, mainly in the women subsample, the predictive role of BMI, of the total score of suicidability and of attentional impulsivity to the occurrence of BE symptoms, with the occurrence of traumatic events (as a more distal correlate) revealing significant associations, but not predicting these symptoms.
