Abstract: introduction body image is a concept which involves the feelings, attitudes and perceptions people have about their own body, and is influenced by the adoption of social standards. body image studies are used in the field of eating disorders research in order to analyze the degree of body dissatisfaction. however, most of the scales proposed to assess body image have been developed in anglo-saxon and european countries. therefore, research on this topic in other socio-cultural contexts requires the standardization and validation of culturally adapted instruments. the aim of the present study was to determine and discuss the reliability and validity of a mexican scale which measures body image. additionally, comparisons regarding body dissatisfaction, internalization of the aesthetic ideal of thinness, social influence, age and body mass index (bmi) were made between groups of female college students with and without disordered eating. materials and methods the sample of this study comprised 508 female college students from the universidad autónoma del estado de méxico, selected by means of a probabilistic stratification procedure taking into account the proportion of female students enrolled in each academic area of the university. their average age was 20.1 years; their mean weight was 57.2 kg with an average height of 1.58 m, whereas the average bmi was 22.8. based on the theoretical assumptions, three indicators were defined to structure the body image scale: body dissatisfaction, social influence and the internalization of the aesthetic ideal of thinness, measured by a five-point likert-type scale ranging from never (1) to always (5). a pilot study was carried out in a population of 100 college women; as a result, some adjustments were made in the instructions and in the order of the items. additionally, a content validation was conducted through the judgments of four professional experts in the clinical mental health area. the scale contains thirty-three items;

Abstract: Objetivo: obtener la validez y consistencia interna de un cuestionario para púberes mexicanos, hombres y mujeres, que evalúe factores de riesgo asociados a trastornos de la conducta alimentaria. Sujetos y método: El cuestionario se aplicó a una muestra no probabilística, de púberes estudiantes de la ciudad de México (504 hombres y 511 mujeres), con edades de 11 a 15 a os de edad, con una media de 12,13. Se realizó un análisis de consistencia interna (alfa de Cronbach) y un análisis factorial de componentes principales con rotación oblimin por el método de máxima verosimilitud. Resultados: Ambos instrumentos arrojaron 5 factores, con una buena consistencia interna, alcanzando un valor total de alpha de Cronbach de 0,75 para hombres (55,6% de varianza explicada) y 0,83 para mujeres (57,6% de varianza explicada). Conclusión: El instrumento resultó válido en hombres y mujeres, para medir factores de riesgo asociados a trastornos alimentarios, principalmente socioculturales, conductas alimentarias y desarrollo puberal.

Abstract: objective: to describe the prevalence of abnormal eating behaviors in a population-based nationwide survey. material and methods: a stratified, probabilistic, multistage design sampling process was used. the brief questionnaire for risky eating behaviors was included in the mexican health and nutrition survey 2006 (ensanut 2006) and administered to participants 10-19 years old (n= 25 166). the study had the power to describe nationwide characteristics by age, regions and urban/rural settings. results: a high risk for having an eating disorder was found in 0.8% of the total participants (0.4% male adolescents and 1.0% female). inhabitants in large cities showed higher risk for having an abnormal eating behavior compared to subjects living in other settings. the highest prevalences were found in males > 15 years old and females > 13 years old for all evaluated behaviors. conclusions: results show less prevalence of risky eating behaviors among adolescents in comparison to other populations. the female/male ratio was 3:1, far different from the 9:1 shown in a previous study in mexico city, but similar to results from the us national eating disorders screening.

Abstract: the term <> is immediately related to food consumption. however, eating is a complex behavior mediated by external factors. eating is not exclusively related to satisfying individual's needs or nutritional requirements. eating behavior alteration has originated disordered eating (de) and eating disorders (ed), such as anorexia nervosa, bulimia nervosa and binge eating syndrome, where patterns of food ingestion are altered and people forget the importance of maintaining a balance between caloric ingestion and caloric expenditure, with repercussions in the nutritional status and in the individual's health. recent studies carried out in mexican population have confirmed the presence of de, particularly among adolescents and young adults, and predominantly in females. data from a representative sample of students with a mean age of 14.5 years reported an increase in the proportion of de between the 1997 and the 2003 assessments (1.3% in males and 3.4% in females) compared to the 3.8% in males and 9.6% in females registered in 2003. more recent data from the national nutrition and health survey 2006, in a representative sample of adolescents 10 to 19 years of age, indicated a prevalence of 0.8% (1% in females and 0.4% in males), with higher scores in the north and center-west areas of the country, followed by the central and south-south-east areas, with almost two-fold percentages in the urban settings compared to the rural ones. the multifactorial origin of ed is well known and among the most studied risk factors are: eating behaviors, high body mass index (bmi) and body thin-ideal internalization. research findings indicate that overweight and obese adolescents are at more risk for body dissatisfaction, as their physical appearance is farther away from being as the one promoted by society and the media. the sociocultural pressure to be thin has promoted the internalization of the idea that being thin is synonymous to success, greater social acceptance,

Abstract: Introducción En términos generales, se acepta que la comorbilidad psiquiátrica puede incrementar la gravedad, la cronicidad y la resistencia al tratamiento de los trastornos psiquiátricos. En diversos estudios en todo el mundo se ha estimado que la prevalencia de trastornos por consumo de alcohol en mujeres con conductas alimentarias de riesgo (CAR) se sitúa entre el 2.9 y el 48.6%. Es importante se alar que los estudiosanteriores no han considerado el análisis de las variables que podrían explicar la comorbilidad entre las CAR y el consumo de alcohol en los adolescentes, tales como la impulsividad, que es la variable considerada como la más importante para explicar dicha comorbilidad. Por otro lado, la mayor parte de la literatura ha estudiado a población adulta en hospitales psiquiátricos o a sujetos que ya han cumplido con los criterios diagnósticos de los trastornos de la conducta alimentaria (TCA) y de los trastornos por uso de alcohol. Se ha considerado que dichas poblaciones ya han desarrollado trastornos psiquiátricos comórbidos y que la impulsividad puede ser un rasgo inespecífico que agrava la situación psiquiátrica de una persona y que de esa forma sea más probable que acuda a una institución hospitalaria. Por lo tanto, es posible que la participación de la impulsividad en la comorbilidad entre los TCA y el consumo de alcohol no sea similar en la población general, sobre todo en la que no ha desarrollado los trastornos aún. Por lo tanto, consideramos importante aclarar la participación de la impulsividad en la comorbilidad entre las conductas alimentarias de riesgo (CAR) y el consumo excesivo de alcohol (CEA) en la población general y especialmente en aquellos sujetos en riesgo de presentar estos trastornos. Para ello se consideró importante analizar la asociación entre la impulsividad y la coexistencia de las conductas alimentarias de riesgo y el consumo excesivo de alcohol en estudiantes de sexo femenino de entre 15 y 19 a os en escuelas públicas del Estado de México.
