Introducción: el trastorno por atracón (TpA) es la psicopatología alimentaria más prevalente entre la población, por lo que son necesarios instrumentos validados de tamizaje para su detección y diagnóstico oportuno. Objetivo: confirmar la estructura factorial de la Escala de Atracón Alimentario (BES) a través del análisis factorial confirmatorio (AFC) y proponer un punto de corte en una muestra mexicana. Método: la muestra fue no probabilística constituida por 421 personas (66.7% mujeres) con un rango de edad de 18 a 57 años (M = 23.92, DE = 7.38) provenientes de la ciudad de México y zona metropolitana. Todos los participantes contestaron dos instrumentos que evaluaban sintomatología de TpA y aquellos que puntuaron alto fueron entrevistados para diagnóstico del trastorno. Resultados: de las 421 personas, se diagnosticaron 60 con TpA. Se observó una adecuada consistencia interna del instrumento y el AFC ratificó la estructura de la versión original de dos factores: 1) manifestaciones cognitivas y 2) manifestaciones conductuales, presentando un buen ajuste de los datos. Se exploraron diferentes puntos de corte, observando el 17 como el más adecuado de acuerdo con los valores de sensibilidad (98%) y especificidad (93%). Conclusión: estos resultados contribuyen al desarrollo de una medida de evaluación de atracón alimentario en la población mexicana y proporciona una exploración del BES válida para la detección de sintomatología de TpA tanto en hombres como en mujeres.

To evaluate the effectiveness of a multidisciplinary online intervention (psychological, medical, and nutritional) in women with binge eating disorder (BED). Method: 5 women diagnosed with BED with a mean age of 43.2 years and a mean initial body weight of 90 kg participated. The treatment was carried out during 24 sessions, each of two hours per week; the first hour was group therapy and the second individual. There were four moments of evaluation: pre, post and two follow-ups. Results: The comparisons were made through the non-parametric Friedman test, finding a statistically significant decrease in binge eating symptoms before χ1= 30.30 at the second follow-up χ2 =10.80 (x²=12.84; p=.005), symptoms of anxiety χ1= 28.80, χ2=12.40 (x²=10.83.96; p=.013) and depression χ1= 19.80, χ2=4.0 (x²= 10.18, p=.017). Improvement was observed in comprehension χ1= 21.00, χ2=30.20 (x²=9.63; p=.025) and emotional regulation χ1= 28.40 χ2=33.00, (x²=7.77; p=.050). The patients reduced their body weight, improved their eating habits by introducing fruit and vegetables daily and included physical activity in their daily routine, performing 20 to 30 minutes a day. From the objective clinical change, a positive change was observed in the variables addressed in treatment in all the participants. Conclusions: The online multidisciplinary intervention was effective in the treatment of BED in women.

Background Binge eating disorder (BED) is the most frequent eating behavior among the general population (Guerdjikova in Med Clin 103:669–680, 2019). Many studies on interventions and BED treatments have been carried out in the United States and Europe, few have been reported in Latin American populations. People with this disorder not only have physical consequences of it but also social and psychological ones, therefore a multidisciplinary treatment approach is a good option to treat this condition. Objective To evaluate the feasibility of a multidisciplinary online intervention (i.e., psychological, nutritional, and physical activity) in patients with BED. Method The design was a case series study of two clinical treatment groups, with pre-test and post-test psychometric measures along with two follow-ups (at 2 and 6 months). Fifteen people diagnosed with BED (2 men and 13 women), with a mean age of 34.93 years (SD=11.91) and a mean initial BMI of 42, participated in this study. The treatment was carried out over the span of 28 sessions, each one being two hours per week consisting of 1 hour of group therapy and 1 hour of individual therapy. There were four evaluations: pre, post and two follow-ups. Results Five patients did not complete the treatment (30%). The comparisons were made through the non-parametric Friedman test, finding a statistically significant decrease in binge eating symptoms (x2=15.57; p=.001), anxiety symptoms (x2=15.96; p=.001) and depression (x2=15.03; p=.002). There was an improvement in clarity (x2=11.60; p=.010) and emotional regulation (x2=7.75; p=.050), only in women. The patients reduced their body weight, and improved their eating and exercise habits by introducing fruits and vegetables and including 20-30 minutes of physical activity into their daily routine. Regarding the Objective Clinical Change Index, in terms of the objective clinical change, a positive change was observed in all the variables addressed. Conclusions The data presented allowed us to conclude that the online multidisciplinary intervention was effective in the treatment of BED. Trial registration Retrospectively registered

Background: Binge eating disorder (BED) is the most frequent loss of eating behavior among the population and the one that has received the least study in its treatment. Many studies on interventions and BED treatments have been carried out in the United States and Europe, few have been reported in Latin American populations. People with this disorder not only have physical consequences but also social and psychological ones, so a multidisciplinary treatment is a good alternative to treat this condition.

Method: 15 Fifteen people diagnosed with BED (2 men and 13 women) with a mean age of 34.93 years (SD=11.91) and a mean initial BMI of 42 participated in this study. The participants were divided into two groups according to the severity of the disorder. The treatment was carried out over 28 sessions, each being two hours per week consisting of 1 hour of group therapy and 1 hour of individual therapy. There were four evaluations: pre, post and two follow-ups. Results: Five patients did not complete the treatment (30%).

Regarding the Objective Clinical Change Index (OCC) From the objective clinical change, a positive change was observed in all the variables addressed. Conclusions: The data presented allowed us to conclude that the online multidisciplinary intervention was effective in the treatment of BED. Trial registration:Retrospectively registered
