Effectiveness of an e-Health Quasi-Randomized Controlled Universal Prevention Program for Eating Disorders in Spanish Adolescents.

Eating disorders (EDs) and sub-threshold conditions are prevalent in the adolescent population. Unfortunately, most preventive interventions have been targeted at emerging adults and the effectiveness of online prevention programs has yet to be determined in adolescents. This study sought to examine the short-term effectiveness of a universal e-Health psychoeducational prevention program for EDs compared to a control (non-intervention) group in Spanish adolescents. Using a quasi-randomized trial design, a total of 161 [% girls: 45.96; Mage(SD) = 12.43 (0.43)] adolescents from 5 participating schools were allocated to two intervention arms: (1) psychoeducational intervention (n = 79) and (2) wait-list control (n = 82). The intervention was delivered over 3 months through 3 modules that were accessible 24/7 and 3 school sessions guided by the students´ tutors focusing on nutrition, promoting a healthy lifestyle, mitigating body concerns, and social pressures. Participants completed an online assessment battery including the Eating Attitudes Test (EAT-26) and measures of self-esteem, family disruption, compliance with the Mediterranean diet, and lifestyle. Correlational analysis showed small to moderate relationships between self-esteem and family function (rho = 0.413, p = 0.001), BMI (body mass index) and the EAT-26 dieting subscale (rho = 0.417, p = 0.001), physical activity and the bulimia subscale (rho = - 0.237, p = 0.003), and self-esteem and the dieting subscale (rho = - 0.223, p = 0.004). At the post-intervention assessment, the intervention group showed a statistically significant reduction in ED risk (EAT-26) (d = - 0.323, p = 0.040) and the oral control subscale (d = 0.327, p = 0.038). The e-health intervention including tutor-led digital components was effective for reducing ED risk in children. Results must be interpreted with caution due to the low statistical power and the limited sample size. Large scale randomized controlled trials with longer follow-ups will be needed to bolster the evidence.

The Influence of Sleep and Reading on Overweight of the Children.

The active leisure, in particular reading, and hours of sleep play an important role in health and body mass index (BMI) in children. The aim of this study is to analyze, by means of path analysis, how these variables interact in influencing children's weight. Two hundred and ninety-one children took part in the study. Their BMI was calculated and they were interviewed. A path analysis indicates that spending more time on leisure-time reading facilitates the control of BMI in two ways. Firstly, it is associated a greater number of active leisure activities (r = .35 p < .001) and predicts more hours of sleep (ß = .13 p < .05), which in turn predicts a lower BMI (ß = -.15 p < .001). Furthermore, it has been observed that spending more time reading is associated with less time spent on sedentary leisure activities (r = -.17 p < .001). It would appear that in order to control overweight in children, it is necessary to foster a well-ordered lifestyle. Reading as the last activity of the day can make a significant contribution to this process.

Differences between individualist and collectivist cultures in emotional Facebook usage: relationship with empathy, self-esteem, and narcissism / Diferencias entre culturas individualistas y colectivas en el uso emocional de Facebook: relación con la empatía, la autoestima y el narcisismo

BACKGROUND: Adolescents are one of the groups who most use social networks in an emotional way, to express their own emotions and to empathize with the emotions of others. Although personality factors; namely, empathy, self-esteem, and narcissism appear to play an important role in this usage, the contribution of cultural variables has yet to be examined. The aim of this study is to examine cross-cultural variations in Facebook usage and the relationship of those variations with empathy, self-esteem and narcissistic personality factors. METHOD: Using a sample of 479 Spanish adolescents (220 females) and 405 Thai adolescents (224 females), the Use of Facebook Questionnaire was applied, and empathy, self-esteem and narcissism personality traits were measured. RESULTS: Findings suggested variations between Thai and Spanish samples at the intra- and inter-cultural level. The Thai sample had higher scores in Affective Empathy but lower scores in Cognitive Empathy, used Facebook more, and engaged in more emotional and empathic expression when using Facebook. Also, results also show interesting differences related with the interaction between gender and country. CONCLUSIONS: We discuss the results in relation to Hofstede's criteria about the differences between Eastern and Western societies. We highlight the need for longitudinal studies about this topic

ANTECEDENTES: los adolescentes son el grupo de población que más usan las redes sociales de forma emocional para expresar sus emociones y para empatizar con las emociones de otros. Mientras que factores de personalidad como empatía, autoestima y narcisismo parecen desempeñar un papel importante en este uso, la contribución de las variables culturales no ha sido examinada. El objetivo de este estudio es examinar variaciones interculturales en el uso de Facebook, y su relación con la empatía, autoestima y narcisismo. MÉTODO: usando una muestra de 479 adolescentes españoles (220 mujeres) y 405 adolescentes tailandeses (224 mujeres), se aplicó el Cuestionario de Uso de Facebook y se midieron los rasgos de empatía, autoestima y narcisismo. RESULTADOS: los resultados sugieren variaciones entre las muestras españolas y tailandesas a nivel intra e intercultural. La muestra tailandesa puntuó más alto en Empatía Afectiva, pero más bajo en Empatía Cognitiva, y usó más Facebook expresando emociones y empatía. También se obtuvieron resultados relacionados con la interacción entre sexo y país. CONCLUSIONES: se discuten estos resultados en relación con los criterios de Hofstede acerca de las diferencias entre las sociedades occidentales y orientales. Se destaca la necesidad de estudios longitudinales

Relationship of Social and Family Support with Acceptance of Pain in Patients with Fibromialgia. Acceptance of chronic pain and relational context have been shown to be important in patients with fibromyalgia. The aim of this study was to know if social and family support are related to the acceptance of pain in these patients. The study involved 55 people with fibromyalgia. To collect the data, a sociodemographic questionnaire was used and the impact of fibromyalgia, pain acceptance, family satisfaction, family cohesion and social support were evaluated. Regression analysis shows how involvement in activities is predicted by family satisfaction and the year of diagnosis. Family cohesion predicts openness to pain, and full acceptance is predicted by family satisfaction, social support and the year of diagnosis. It is concluded that family satisfaction and social support predict the acceptance of chronic pain, regardless of the physical impact of the disease. The need for a family intervention with patients with fibromyalgia in order to enhance their process of acceptance of pain is pointed out. In addition, it is considered necessary to stop the delay in the diagnosis for a better prognosis

Skipping breakfast, sedentarism and overweight in children.

To show by use of path analysis how in children of 9 and 10 years of age the known relationship between breakfast and high body mass index (BMI) is mediated by sedentary leisure time activities. A random sample of 291 9-year-old and 10-year-old school children from the Principality of Asturias (Spain) was taken. A transversal design was used, their weight and height were measured and an individual standardized interview was carried out in which they were asked about their breakfast habits and the time they spent each week on sedentary leisure activities. Using path analysis, a model was tested in which breakfast habits and leisure time were the independent variables and the BMI was the dependent variable. The results showed that there was an inverse correlation between number of breakfasts and BMI and a direct correlation between the time spent on sedentary leisure activities and BMI. Path analysis showed that the relationship between the frequency with which breakfast was eaten and BMI was mediated by the time spent on sedentary leisure activities. The above appears to confirm the direct role played by failing to have breakfast in the pandemic of obesity as this habit tends to increase children's BMI. This relationship is, however, mediated by sedentary leisure. According to the data compiled, being overweight in children can only be prevented by modifying not just one of the habits that have been associated with it, but rather the whole group of habits as these appear to make up an obesogenic cluster in which sedentary leisure and not having breakfast are included.

Relationships between sleeping habits, sedentary leisure activities and childhood overweight and obesity.

The aim of this study is to show how sedentary leisure activities and a decrease in hours of sleep interact to lead to an increase in the body mass index (BMI) in children. A random sample of 291 nine-year-old and ten-year-old schoolchildren from Asturias (Spain) was taken. A cross-sectional design was used, the children's weight and height were measured and an individual interview was carried out. Using path analysis, a model was tested in which bedtime, the number of hours spent sleeping and sedentary leisure activities were the independent variables and the BMI was the dependent variable. The results show that sedentary leisure activities and hours spent sleeping are predictors of a greater BMI in children. Moreover, the effect of the time spent sleeping is mediated by sedentary leisure activities. That is to say, it is those children who go to bed late and who use that extra time to watch the television or play with the computer that tend to have a greater BMI. Attention should be drawn to the importance of this fact and to the implications it may have for education and children's health.

Influencia del estado emocional en la sintomatología referida por pacientes con cáncer de mama y cáncer de pulmón durante el tratamiento con quimioterapia / The influence of the emotional state on the physical symptoms of patients with breast and lung cancer during chemotherapy treatment

Analizar la evolución de los síntomas físicos y emocionales y la influencia de la ansiedad y la depresión en el estado físico de los pacientes con cáncer de pulmón o cáncer de mama a lo largo del tratamiento con quimioterapia intravenosa (QT).Método Sesenta y seis pacientes, 29 con cáncer de mama y 37 con cáncer de pulmón, fueron evaluados antes de iniciar el tratamiento, finalizado el primero, segundo y último ciclo de QT, mediante el HAD y un cuestionario de síntomas. Resultados La ansiedad se redujo significativamente al finalizar el tratamiento en todos los participantes pero la depresión solo disminuyó en los pacientes con cáncer de pulmón. Durante el tratamiento se incrementó significativamente la astenia, la disnea y las náuseas. El insomnio disminuyó a lo largo del tiempo en los pacientes con cáncer de pulmón y se incrementó en los pacientes con cáncer de mama. Al eliminar la varianza compartida con ansiedad y depresión, se comprobó que la mayoría de los cambios en los síntomas fueron atribuibles a los factores tiempo y tipo de cáncer. Conclusiones El estado emocional no parece influir significativamente, durante el tratamiento con QT, en la presencia e intensidad de la sintomatología (AU)

Aim to analyse the evolution of the physical and emotional symptoms, and the influence of anxiety and depression on the physical state of breast or lung cancer sufferers during treatment with intravenous chemotherapy (CT).Method A total of 66 patients, 29 suffering from breast cancer and 37 suffering from lung cancer, were evaluated before the treatment, and after completing the first, second and last cycle of CT using the Hospital Anxiety and Depression (HAD) and the Symptoms Questionnaires. Results Anxiety was reduced greatly in all patients once the treatment was over, but depression was only reduced in lung cancer sufferers. Throughout the treatment, fatigue, dyspnea and nausea significantly increased in all patients. Sleeplessness decreased over time in patients with lung cancer, but increased in those patients with breast cancer. By introducing the HAD scores as covariables, it was found that most of the differences were due to the time factor and the type of cancer. Conclusions During treatment with intravenous chemotherapy (CT), the emotional state does not seem to have a significant influence on the presence and severity of the symptoms (AU)

El papel del psicólogo clínico en el tratamiento del sobrepeso y la obesidad / No disponible

En este trabajo se presentan los elementos básicos de un programa psicológico para el control del peso. En él se parte de un hecho que habitualmente no se tiene en cuenta en los programas comerciales más comunes y que no son eficaces para mantener la pérdida de peso a medio y largo plazo. Esto es, que la pérdida de peso sostenible sólo es posible cuando se respeta los límites que cada organismo marca. Esto implica un trabajo de reajuste de expectativas, mostrando a los clientes cuanto peso es posible perder, enseñando un cierto autocontrol alimentario, promoviendo cambios en el estilo de vida y proponiendo un modo distinto de relacionars con el propio cuerpo (AU)

In this paper, we present the basic structure of a psychological program for weight control. It is rooted in a fact that is usually not taken into account in most common commercial programs, which are not effective in maintaining medium and long-term weight loss. That is, sustainable weight loss is only possible when we respect the limits set in each organism. This work involves a readjustment of expectations showing how much weight it is possible to lose, teaching self-control techniques, promoting changes in lifestyle and proposing a different way of relating to one’s own body (AU)

Repercusión de la ansiedad y depresión en el estado físico y funcionalidad de enfermos oncológicos durante el tratamiento con quimioterapia / Impact of anxiety and depression on the physical status and daily routines of cancer patients during Chemotherapy

Se describe la evolución de la sintomatología, estado emocional y rutinas cotidianas en pacientes con cáncer de mama y cáncer de pulmón durante el tratamiento con quimioterapia (QT), y se analiza la mediación de la ansiedad y depresión en el estado físico y funcionalidad. 66 pacientes, 29 con cáncer de mama y 37 con cáncer de pulmón, se evalúan antes de iniciar el tratamiento, finalizado el primero, segundo y último ciclo de QT, mediante el HAD, escalas de apreciación y entrevista. Menos de un 30% alcanzan puntuaciones en el HAD indicativas patología ansiosa o depresiva. Se incrementó significativamente el cansancio, fatiga y náuseas y se interrumpen las actividades laborales y de ocio. La preocupación por el futuro de allegados y el insomnio se incrementan significativamente a lo largo del tiempo en pacientes con cáncer de mama, mientras que se reducen en pacientes con cáncer de pulmón. Al introducir como covariables las puntuaciones obtenidas en el HAD, se comprueba que la mayoría de diferencias son atribuibles a los factores tiempo y tipo de cáncer. Las alteraciones emocionales no parecen tener, durante el tratamiento con QT, un peso relevante en la sintomatología y cambios en la vida cotidiana referidos por el paciente oncológico (AU)

The evolution of symptoms, emotional state and daily routines in patients with breast cancer and lung cancer during treatment with intravenous chemotherapy (CT) is described and the influence of anxiety and depression on these variables is analyzed. 66 patients, 29 with breast cancer and 37 with lung cancer, were evaluated before starting treatment, and after completing the first, second and last cycle of CT using the Hospital Anxiety and Depression Scale (HADS), rating scales and interview. Less than 30% of the patients showed clinical anxiety or depression according to the HADS. Throughout the treatment, tiredness, fatigue and nausea increased significantly and work and leisure activity decreased. Concern about the future of relatives and insomnia increased significantly over time in patients with breast cancer whereas they decreased in patients with lung cancer. By introducing the HADS scores as covariates, it was found that most differences are due to the time factor and the type of cancer. During treatment with CT, emotional disturbances do not seem to have significant impact on the symptoms and changes in daily life reported by cancer patients (AU)

Eating habits and attitudes and their relationship with Body Mass Index (BMI)

Background and Objectives: To study the differences in eating attitudesand habits between subjects of normal weight and subjects who are overweight and to analyzein each group the relationship between these habits and attitudes and BMI, takinggender as a modulating variable.Methods: A total of 191 subjects, 117 women and 74 men, took part in this study. 102subjects made up the overweight/obesity group and 82 subjects made up the controlgroup. All of them were given a questionnaire comprising 26 items (EAT 26 Eating AttitudesTest) plus an additional group of 10 extra items.Results: The overweight group shows a significantly higher score in mood-related ingestionthan the group with normal weight. Subsequent analyses indicate that while in theoverweight/obesity group there is a positive correlation between the oral control scale andBMI, in the normal weight control group there is a negative correlation between oral controland BMI. Amongst the women in the overweight group a significant relationship wasobserved between skipping meals, oral control and BMI. 50.7% of the dieters stated thattheir attempts to lose weight had generally been followed by an even greater weight increase.Furthermore, 88.5% of the dieters stated that they had been unable to maintain theweight loss in the long term.Conclusions: The results indicate that the same restrictive practices can have differenteffects depending on the BMI and the sex of the subjects (AU)

Actividades extraescolares, ocio sedentario y horas de sueño como determinantes del sobrepeso infantil / The relationship between extra school activities, short sleeping, sedentary leisure and childhood overweight

In this study, the relationship between extra school activities, physical activity, sedentary leisure, sleeping and the Body Mass Index (IMC) was analyzed. The sample consisted of 72 students, 41 girls and 31 boys, aged between 9 and 10 years and half. An individual interview was made in which the children were asked out about the TV programs that they watched each one of the days of the week, the time that they spent with the console and the computer, the time that they dedicated to the sports and other physical activities. The results showed that the sedentary leisure (number of hours of television, computer and console) is associated with an increase of the IMC. But sedentary leisure is also related with short sleeping and with the extra school activities. The implications of these results on the study childhood overweight are discussed (AU)

En este estudio se analizan, a través del path analysis, la relación entre las actividades extraescolares, el ocio sedentario, el sueño y el Índice de Masa Corporal (IMC). Participó una muestra de 72 alumnos, 41 chicas y 31 chicos, de cuarto de primaria, con una edad comprendida entre los 9 y los 10 años y medio. Para ello se realizó una entrevista individual en la que se preguntaba a los niños los programas que veían en la televisión cada uno de los días de la semana, los juegos de consola y ordenador que utilizaban a diario, el tiempo dedicado a los deportes y a las actividades extraescolares (que incluía horas de juego en el parque infantil). Los resultados pusieron de manifiesto que el ocio sedentario (número de horas de televisión, ordenador y consola) se asocia con un incremento del IMC. Sin embargo, ese ocio sedentario viene explicado a su vez por un menor número de horas de sueño que también esta influido por las actividades extraescolares. Se discuten las implicaciones sobre el estudio del estilo de vida y sobrepeso infantil (AU)

Actividad física, ocio sedentario, falta de sueño y sobrepeso infantil / Physical activity, sedentary leisure, short sleeping and childhood overweight

En este trabajo se analizó, utilizando el path analysis, la relación entre la actividad física no reglada, actividad física deportiva, el ocio sedentario, las horas de sueño y el índice de masa corporal (IMC). Participaron una muestra de 103 alumnos, 59 chicas y 44 chicos, de cuarto de primaria con una edad comprendida entre los 9 y los 10 años y medio. Se realizó una entrevista individual en la que se preguntaba a los niños los programas que veían en la televisión cada uno de los días de la semana y los juegos con los que jugaban en la consola y el ordenador, el tiempo dedicado a los deportes, juegos y actividades extraescolares. Los resultados pusieron de manifiesto que el ocio sedentario (número de horas de televisión, ordenador y consola) mantiene una relación significativa e inversa con las horas de sueño, la actividad no reglada (horas de juego y actividades extraescolares) y la actividad física deportiva. Las diferencias entre este modelo y el que se ha obtenido en estudios previos se discuten a partir del procedimiento de reclutamiento de los participantes
