The objective of this study is to assess the effect of alcohol consumption, anxiety, and food restriction before and after consuming alcohol and body image on the risk of anorexia and bulimia in college students from Tijuana, Baja California, through predictive statistical models. A quantitative, descriptive, and cross-sectional design and a non-probabilistic sample of 526 college students from Tijuana, Baja California, México were used. Application of the scales (with acceptable psychometric properties) was conducted in classrooms. Through path analyses, four models were found with adequate indicators of goodness of fit: (1) risk of anorexia in women [Chi Square (X²) = 5.34, p = 0.376, Adjusted Determination Coefficient (R²)= 0.250]; (2) anorexia risk for men (X² = 13.067, p = 0.192, R² = 0.058); (3) risk of bulimia in women (X² = 3.358, p = 0.645, R² = 0.202); and bulimia risk for men (X² = 14.256, p = 0.075, R² = 0.284). The findings provide empirical evidence for the food and alcohol disturbance model.

Although anxiety seems to be a constant in patients with eating disorders, little is known about its interaction with other variables. Therefore, the main objective of this study was to compare the risk of anorexia nervosa (AN) and bulimia nerviosa (BN) based on the sex of participants, degree of anxiety and city of residence. The study is a non-experimental and cross-sectional design. The sample was nonrandom and consisted of 857 college students (67% female and 33% male) with a mean age of 21.96 years (SD=4.84), 42% were Mexico City residents and 58% were from Ensenada city. Participants completed two self-report scales, one for assessing risk of AN and BN, and other to measure anxiety. The findings show that the degree of anxiety differs according to the city of residence, being higher in Ensenada city. In addition, a significant interaction was found between the variables; for instance, the risk of BN in Ensenada city residents increases as anxiety increases. Therefore, it is confirmed not only the importance of sex and anxiety on eating disorders, but also the interaction of these two variables with the city of residence.ResumenAunque la ansiedad parece ser una constante en los pacientes con trastorno de la conducta alimentaria, poco se sabe sobre su interacción con otras variables. Por tanto, el objetivo principal de este estudio fue comparar el riesgo de anorexia nerviosa (AN) y bulimia nerviosa (BN) en función del sexo, el grado de ansiedad y la ciudad de residencia. Se trabajó con un diseño no experimental-transversal y una muestra no probabilística conformada por 857 estudiantes universitarios (67% mujeres y 33% hombres), con edad promedio de 21.96 años (DE=4.84), el 42% residentes en la Ciudad de México y el 58% en la ciudad de Ensenada. Los participantes completaron dos escalas de autorreporte, una para evaluar el riesgo de AN y BN, y otra para medir la ansiedad. Los hallazgos evidencian que el grado de ansiedad difiere en función de la ciudad de residencia, siendo mayor en Ensenada. Además, se encontró una interacción significativa entre las variables; por ejemplo, en los residentes en la ciudad de Ensenada, el riesgo de BN se incrementa cuando la ansiedad aumenta. Por tanto, se confirma no solo la relevancia del sexo y la ansiedad sobre los trastornos de la conducta alimentaria, sino también de la interacción de dichas variables con la ciudad de residencia

El riesgo de desarrollar trastornos alimentarios es un problema real en la juventud universitaria y puede acompañarse de múltiples factores de índole psicológico, por tal motivo, el objetivo del estudio fue identificar los factores psicológicos que predicen el riesgo de desarrollar un trastorno alimentario en la población universitaria del sur de Tamaulipas. Realizamos un estudio transversal, comparativo y predictivo en 169 personas universitarias de ambos sexos, usando el Test de Actitudes Alimentarias (EAT-26), el Cuestionario de la Forma Corporal, el Inventario de Depresión de Beck, el Inventario de Ansiedad de Beck y la Escala de Autoestima de Rosenberg. La prueba t de Student mostró que el riesgo de trastorno alimentario, la insatisfacción corporal y la autoestima fue mayor en la muestra femenina que en hombres. El Modelo de Regresión Múltiple indicó que los factores predictores del riesgo de trastorno alimentario en la muestra femenina fueron la insatisfacción corporal y la ansiedad, mientras que, en la muestra masculina, únicamente se detectó la insatisfacción corporal como predictor. Los hallazgos resaltan la insatisfacción corporal como un factor predisponente en el riesgo de trastornos alimentarios en ambos sexos, elemento que puede considerarse en el fortalecimiento y construcción de estrategias de prevención en muestras similares.

Depression is a type of mood disorder that can impact individuals of any age. A variety of factors, including biological, psychological, and environmental factors, can contribute to the likelihood of developing depression. If the environment in which a person exists does not support its occurrence, the disorder may not manifest. The current research follows a retrospective, correlational approach, utilizing a non-probability sample of 557 high school students from public schools in Mexico City. This sample includes 181 males and 376 females, aged between 15 and 18 years, with an average age of 15.66 and a standard deviation of 0.68. The main objective of this research is to identify the variables that serve as risk factors for the development of depressive disorders in Mexican adolescents in high school. The data show that 78% of the adolescents in the total sample were at risk of depression, which is consistent with what has been reported by other researchers. The regression model shows that alcohol and drug consumption is associated with and influences the emergence and presence of depressive symptomatology and major depressive disorder. Adolescents with different sexual orientations than heterosexuals are twice as likely to suffer depression and emotional dysregulation. It was confirmed that the developmental stage and adolescence contributes as a context that favors the evolution of such a symptomatology.

The objective of this study was to evaluate the validity and reliability of OTESSED, an online test for the self-detection and prevention of risk factors for eating disorders and related problems, such as depression, social anxiety, and self-injury, in samples of male and female adolescents. Participants formed a non-probability sample of N = 577 high school students. The mean ages of boys and girls were the same (Mage = 15.61; SD = 0.73). Among the main results, scales of depression, self-injury, social anxiety, and risky eating behavior (REB) with construct validity (CFA) were obtained. The first two showed the same structure (two factors per sex), with an appropriate reliability omega value (0.92), and a similar percentage of explained variance (≥50). The REB scale presented two factors for boys and three for girls, with an appropriate omega value (0.88) and explained variance percentage (0.56). The instrument validation process was completed, meeting the discriminant validity criterion for each scale of the OTESSED.

Adolescence is a difficult stage, a period of risk for developing disorders, including depression and self-injurious behavior. A non-random sample was drawn (n = 563) from first-year high school students (32.8%) 185 males and 378 females (67.14%) from public schools in Mexico. The age range was 15 and 19 years, with a mean age of 15.63 (SD = 0.78). According to the results, the sample was divided into n1 = 414 (73.3%) adolescents without self-injury (S.I.) and n2 = 149 (26.4%) S.I. adolescents. In addition, results were obtained on methods, motives, time, and frequency of S.I., and a model was generated in which depression and first sexual experience obtained the highest Odd Ratio and d values in their relationship with S.I. Finally, we contrasted the results with earlier reports and concluded that depression is an important variable in S.I. behavior. Early S.I. detection will prevent the aggravation of S.I. and suicide attempts.
