ABSTRACT
Introducción y objetivo: Este estudio tuvo como objetivo examinar la relación entre el estrés agudo y la ingesta de alimentos utilizando una muestra de personas sin trastornos emocionales. Con el fin de manipular el estrés y evaluar la relación antes mencionada, se diseñó un escenario experimental, a través de una versión modificada del protocolo de inducción del estrés social, Trial Stress Social Test (TSST). Material y métodos: La muestra final incluyó a 82 participantes entre las edades de 18 y 30 años, que fueron asignados aleatoriamente en dos grupos. Los participantes asistieron a dos sesiones. Al principio, respondieron cuestionarios que recopilaban información sobre estrés - para garantizar la equivalencia de los grupos antes de cualquier exposición al experimento-. En la segunda sesión, para cada actividad asociada con el protocolo TSST, se evaluó el estrés percibido. Además, se evaluó la ingesta de alimentos. Para el análisis, se controlaron estadísticamente seis covariables: edad, sexo, IMC, alimentación emocional, restricción de alimentos y food craving. Además, la ingesta de alimentos se evaluó con la categoría: cantidad de alimentos poco saludables. Resultados: A través del análisis de regresión logística, se descubrió que, en condiciones de estrés agudo, una persona sana podría tener una mayor ingesta de alimentos poco saludables.Conclusiones: Las implicaciones teóricas y prácticas de los resultados contribuyen al desarrollo de investigaciones futuras en el campo de estudio.(AU)
Introduction and objective: This study aimed to examine the relationship between acute stress and food intake using a sample of people without emotional disturbances. In order to manipulate the stress and evaluate the aforementioned relationship, an experimental scenario was designed, through a version modified of the Social Stress induction protocol, Trial Stress Social Test (TSST). Material and methods: The final sample included 82 participants between the ages of 18 and 30 years, who were randomly assigned into two groups. Participants attended two sessions. In the beginning, they answered questionnaires that gathered information about: stress to guarantee the equivalence of the groups before any exposure to the experiment. In the second session, for each activity associated with the TSST protocol, the perceived stress was evaluated. Also, the food intake was evaluated. For the analysis, six covariates were statistically controlled: age, sex, BMI, emotional eating, food restriction and food craving. In addition, food intake was evaluated with the category: quantity of unhealthy food. Results: Through logistic regression analysis, it was found that, under acute stress conditions, a healthy person might have a higher intake of unhealthy food. Conclusions: Theoretical and practical implications of the results contribute in developing future research in the field of study.(AU)

INTRODUCTION: During the Coronavirus (COVID-19) pandemic, a set of daily stressors are being experienced, all this affects people's mental health, leading them to have a set of emotional disturbances. Little is known about how people's age can influence their emotional well-being in the face of prolonged stress generate by the pandemic. OBJECTIVE: To clarify the presence of emotional aspects such as emotional expressiveness and the frequency of positive and negative affections in people with different age in times of crisis. METHODS: The final sample included 297 Chileans between 22 and 68 years old (M = 38.51, SD = 13.85), recruited through an online survey with the appropriate written informed consent. The study was carried out when the pandemic was spreading in Chile. RESULTS: The findings revealed age differences in emotional expressivity and the type of affections experienced. The expression of emotions was more affected by negative affections, the age and the gender of the people. While the avoidance of this emotional expression, by age and affections both positive and negative. Age was a significant predictor of emotional expressiveness. DISCUSSION: Findings suggests that the associations between both variables, varied according to the age group of the people. Furthermore, this finding proposes that although older people are facing the persistent and serious threat of COVID-19, they show better emotional functioning. Which would help to better understand the interaction of both positive and negative life experiences in times of crisis.
ABSTRACT
Morbid obesity as an entity that is associated to numerous clinical complications, an increased mortality and a deterioration of the quality of life, the World Health Organization (WHO) recommends surgical treatments as an alternative. In this sense, the physical and psychological benefits associated with bariatric surgery are well documented. However, the surgery can generate negative effects. The structural changes in the digestive system, coupled with the disruption of the body image especially patients who undergo bypass gastric, reinforce the idea that everything is not positive. Given this reality, this theoretical review is to emphasize the importance of studying the role that psychological variables in adapting to the new body image in these patients.
Al ser la obesidad mórbida una entidad que se asocia a numerosas complicaciones clínicas, a un aumento de la mortalidad y a un deterioro de la calidad de vida de quien la sufre; la Organización Mundial de la Salud (OMS), recomienda considerar como alternativa los tratamientos quirúrgicos. En este sentido, los beneficios físicos y psicológicos vinculados a la cirugía bariátrica están bien documentados. No obstante, la cirugía conlleva efectos negativos en un alto porcentaje de individuos. Los cambios estructurales que produce en el circuito digestivo, sumado a la desorganización de la imagen corporal que sufren los pacientes que se someten especialmente al By-Pass Gástrico, refuerzan la idea de que no todo es positivo. Ante esta realidad, la presente revisión teórica trata de debe de subrayar la importancia de estudiar el papel que tienen las variables psicológicas en la adaptación a la nueva imagen corporal en estos pacientes.
