Desarrollo y validación española de la escala de sucesos vitales estresantes (SVE-I) en escolares (8-12 años) / Development and validation of the stressful life events questionnaire (SVE-I) for Spanish children (8-12 years old)

La acumulación de Sucesos Vitales Estresantes (SVE) supone un factor de riesgo para la salud mental en la infancia, sin embargo, no contamos con un cuestionario en español validado en la segunda infancia. Este estudio presenta el desarrollo y la validación de una nueva escala (SVE-I) de autoinforme para evaluar la acumulación de SVE en menores de 8 a 12 años españoles. Un panel de expertas participó en la evaluación de la adecuación de la escala. Se realizaron comprobaciones en un grupo focal para asegurar la aceptabilidad y comprensión de los ítems. 504 menores de cuatro centros escolares de Madrid (Medad = 10.1; DTedad = 1.28; 56.5 % chicos) participaron en el estudio, completando la batería de cuestionarios. El análisis factorial confirmatorio mostró una estructura de tres factores (estrés familiar, estrés socio-escolar y salud), con una consistencia interna de la escala global adecuada (αordinal = .83). Para la evidencia de validez concurrente, se encontró una asociación positiva entre la acumulación de SVE y la sintomatología ansiosa de los menores. Los resultados indican que la SVE-I es un instrumento válido y fiable. Esta escala pretende ser una herramienta sencilla y útil para el cribado de casos en riesgo desde la escuela y Atención Primaria. (AU)

The accumulation of Stressful Life Events (SVE) is a risk factor for mental health in childhood, however, there is no adequate questionnaire validated in Spanish for its use during childhood. This study presents the development and validation of a new scale (SVE-I), a self-report questionnaire for assessing the accumulation of SVE in Spanish children aged 8 to 12 years. A panel of experts evaluated the adequacy of the scale. The acceptability and understanding of the items were ensured by a small focus group. 504 children from four schools in Madrid (Mage = 10.1; SDage = 1.28; 56.5 % boys) participated in the study, completing a battery of questionnaires. Confirmatory factor analysis showed a structure of three factors: (family stress, socio-school stress, and health), with an adequate internal consistency of the global scale (α = .83). For concurrent validity, a positive association was found between the accumulation of EVS and the anxious symptomatology of the children. The results indicate that the SVE-I is a valid and reliable instrument. This scale aims to be a useful tool in the school context and clinical practice. (AU)

ENTREN-F family-system based intervention for managing childhood obesity: Study protocol for a randomized controlled trial at primary care.

BACKGROUND: Pediatric obesity is a primary public health concern, and designing effective programs for managing it is of the utmost importance. The objective of this study was to describe the protocol study of a three-arm, parallel, randomized controlled trial aimed at assessing the efficacy of a family-system-based intervention ("ENTREN-F" program) for managing childhood obesity, compared to the "ENTREN" program (no "F" - without specific family-system-based workshop) and a control group (behavioral monitoring). METHODS/DESIGN: The ENTREN-F program was a multicomponent family-system-based intervention carried out by a multidisciplinary team in the primary health care setting. The program targeted children between 8 and 12 years with overweight and obesity (P ≥ 85th). Parents were actively involved in the process. The contents were designed using the Cognitive Behavioral Therapy (CBT) principles. The program comprised individual behavioral monitoring, a healthy habits workshop for children and their parents, a CBT workshop for children, and a family-system-based workshop for parents, enhancing parental management skills plus family functioning. The trial's primary outcomes included changes in child body mass index (BMI) z-scores, child's psychological well-being, and family functioning over six months. Secondary outcomes included changes in eating behavior, physical activity, self-esteem, parental distress, parental feeding practices, and parental modeling. DISCUSSION: To our knowledge, this is one of the few randomized controlled trials to assess the efficacy of a multicomponent program that considers health from a comprehensive perspective, trying to improve children's psychological well-being and family functioning besides weight loss. This study, therefore, addresses a gap in the literature. If found to be efficacious, it suggests a new potential health service for translation into National Primary Health Care services in Spain, one of the ten countries with the highest prevalence of obesity in Europe.

Family-reported barriers and predictors of short-term attendance in a multidisciplinary intervention for managing childhood obesity: A psycho-family-system based randomised controlled trial (ENTREN-F).

OBJECTIVE: This study was aimed to examine patient enrolment in the pre-intervention stage, family-reported barriers, attendance rates and underlying predictors of short-term attendance in a family-system-based randomised controlled trial for managing childhood obesity in children aged 8-12-years-old (ENTREN-F). METHOD: Psychosocial and anthropometric measures were collected through primary health referral. The data were used for descriptive analyses of sample characteristics and linear regression analyses. RESULTS: Low enrolment rates and several family-reported barriers were observed in the pre-intervention stage. Logistical barriers were the most frequent family-reported reason for attrition in the different stages of the study. Having a first face-to-face orientation session with the families and the use of motivational interviewing helped to improve adherence in the initial phases of the study. After 6 months of intervention, family based treatments (FBTs) under consideration achieve greater adherence compared with the standard intervention. Moreover, family involvement was a predictor of success for better treatment adherence rates. By contrast, participants who attended a brief standard intervention, mothers with primary education, greater body mass index, higher levels of depressive symptomatology and more critical comments towards their children, children with higher weight status and lower levels of self-reported depressive symptoms at baseline attended interventions less frequently. CONCLUSIONS: In future programmes a comprehensive screening of modifiable factors related to family and their setting characteristics is paramount prior to intervention, identifying key barriers related to drop-out, especially in the case of less-advantaged families.

Using structural equation modeling to understand family and psychological factors of childhood obesity: from socioeconomic disadvantage to loss of control eating.

PURPOSE: Current study aimed to empirically test the Hemmingsson's theoretical model of childhood obesity which emphasizing the importance of family environment and the emotional distress of parents as influential variables in the emotional distress of the child and subsequent weight gain. This study also tested the hypothesis that the emotional distress of the child triggers a weight gain-inducing behavior (loss of control eating) to suppress negative emotions. METHODS: Families of 220 Spanish children participated in the study (28.2% normal, 35.1% overweight and 32.2% obesity), aged between 8 and 12. The evaluation included a clinical interview and a battery of questionnaires. RESULTS: Structural equation models were computed according to the steps proposed by theoretical model. Fit indices were acceptable suggesting that the data adequately fit the hypothesized model. Path coefficients in the final model were statistically significant showing a relationship between socioeconomic status, the emotional distress of parents, family environment, the emotional distress of children, loss of control eating and child's BMI Z-score. CONCLUSION: Considering this relation between emotional distress and child weight status, childhood obesity intervention programs may benefit from targeting family environment and the potential role that food is playing in the regulation of children's distress. LEVEL OF EVIDENCE: Level III: Cohort analytic study.

Linking Psychosocial Stress Events, Psychological Disorders and Childhood Obesity.

There is scientific evidence that supports a strong association between early exposure to stressful life events and the presence of health complications throughout adulthood and, to a lesser extent, in adolescence and childhood. The aim of this study was to examine the accumulation of Psychosocial Stress Events (PSE) and the prevalence of mental disorders in children from 8 to 12 years. The association between these factors and child weight measurements was analysed. A cross-sectional study was conducted among 200 children classified by weight status (obesity, overweight and normal-weight). The assessment was carried out in primary care centres and primary schools. An experienced team carried out a structured medical-psychosocial history and a semi-structured interview aimed at identifying an early diagnosis of psychological disorders. Children filled out a questionnaire to evaluate PSE. The obesity group presented the greatest accumulation of PSE and highest prevalence of psychiatric diagnosis, compared to overweight and normal-weight children. To exceed four or more stressful events was positively associated with psychological problems and child body mass index (BMI z-score). A predictive model confirmed the interaction between a larger number of PSE and the occurrence of a psychiatric diagnosis as variables that predispose children by 26.2 times more to increased weight status. In conclusion, the accumulation of PSE in the family, school and social environments of the children was related to greater psychological distress. If not managed, the likelihood of suffering from other health complications, such as excess weight, may increase. It is important to monitor these variables to ensure positive health outcomes while specifically addressing childhood obesity. This is especially relevant for children from a disadvantaged social background and disharmonious family environments.

Identifying Loss of Control Eating within Childhood Obesity: The Importance of Family Environment and Child Psychological Distress.

This study aims to examine the differences in family environment, psychological distress, and disordered eating symptomatology between children classified by weight status with or without loss of control (LOC) eating and to test a model of the role of emotional regulation of LOC eating based on a dysfunctional family environment. A cross-sectional study was conducted among 239 families. The assessment measured family expressed emotion, family adaptability and cohesion, child levels of depression and anxiety, body esteem, and disordered eating attitudes. The assessment was carried out in primary care centers and primary schools. Child body mass index (BMI) was associated with higher expressed emotion, psychological distress, and disordered eating symptomatology. Children with obesity and LOC presented higher BMI, poorer body esteem, and more disordered eating attitudes than children without LOC. Children with overweight/obesity, both with or without LOC, exhibited higher psychological distress and emotional overinvolvement than normal-weight children. A partial mediation of depression or anxiety and disordered eating attitudes between expressed emotion and LOC was found. Findings support that children with overweight/obesity show more family and psychological distress. Body esteem issues and disordered eating attitudes could alert the presence of LOC in children with obesity. The function of LOC might be to cope with psychological distress that may appear in a dysfunctional family environment.

Feasibility, acceptability, and effectiveness of a multidisciplinary intervention in childhood obesity from primary care: Nutrition, physical activity, emotional regulation, and family.

Childhood obesity is a growing problem with a complex aetiology, for which multidisciplinary interventions are required. Our programme describes a novel structured psychosocial family-based intervention targeting the emotional regulation in childhood obesity, using a train trip metaphor aimed at improving healthy lifestyles for the family. The aims were (a) to describe the feasibility and acceptability of this psychosocial family-based intervention among children with overweight or obesity in primary care and (b) to examine the effectiveness of the "ENTREN-F" programme (with family intervention) compared with the "ENTREN" programme (without family intervention) among Spanish children regarding anthropometric variables, physical activity, emotional well-being, and family functioning. Children were randomly allocated to either ENTREN-F programme (n = 30) or psychological intervention for children (ENTREN, n = 40), and assessments were carried out over time (T0 baseline vs. T1 post/6-month vs. T2 6-month follow-up). Both parent groups expressed high levels of satisfaction with the interventions. ENTREN-F resulted in higher adherence to treatment and was more effective in improving z-body mass index, reducing children's anxiety, and increasing family adaptability than the ENTREN programme. There were no significant changes in parents' emotional well-being and expressed emotion. Both groups improved in the children's emotional well-being and light physical activity. In summary, this multidisciplinary psychosocial family-based intervention was succesful.

A controlled study of an integrated prevention program for improving disordered eating and body image among Mexican university students: A 3-month follow-up.

Obesity and eating disorders are currently two significant health problems in Mexico. The aim of this study was to examine the effects of an integrated prevention program on university students through an exploratory controlled study that targeted specific predisposing factors of disordered eating and obesity related to healthy eating, physical activity, body image satisfaction and perceived pressure to be thin. A total of 388 university students participated (264 females and 124 males) and were assigned either to an intervention condition or one of the two control conditions (study skills vs. nonintervention); each comprised of a total of eight workshops lasting 90 min. The program did not have any effect on the male students. In contrast, there was an interaction effect for time and group in thin-ideal internalization (η2  = 0.04) and in disordered eating attitudes/behaviours (η2  = 0.03); both showed improvements over time only among the female sample. Though, the effect size was insignificant, which means that the effectiveness of this integrated prevention program was limited. Integrated prevention approaches to eating and weight-related problems are still nascent in Mexico, and further research in this field is warranted so as to fine tune future prevention programs.

Prevalence of childhood mental disorders in overweight and obese Spanish children: Identifying loss of control eating.

The aim was to examine the prevalence of childhood mental disorders in overweight/obese pediatric sample and also to explore the relationship between these pathologies and loss of control eating (LOC). Another aim was to assess the association between psychopathology and severity of obesity. A total of 170 children from different Health Centers were evaluated (84 girls and 86 boys; aged 8 to 12 years). Childhood psychological problems were assessed through a standardized diagnostic interview schedule (K-SADS-R) and by questionnaires (STAIC for anxiety, CDI for depression and ChEAT for disordered eating). Loss of control eating episodes were evaluated through the diagnostic interview. Of the sample, 57.06% of overweight/obese children met a DSM-5 diagnosis, typically an anxiety disorder; and 33.53% of the overweight/obese children presented loss of control eating episodes. We found more pathologic eating attitudes (ChEAT) in children who presented LOC versus children who did not. Finally, the scores obtained in the STAIC correlated positively with z-BMI and a positive association was found between z-BMI and the presence of episodes of LOC. These results highlight the importance of including psychological component in the initial assessment and contribute to the understanding of LOC episodes, which are still underestimated in childhood obesity.

Saciación vs saciedad: reguladores del consumo alimentario / Satiation and satiety in the regulation of energy intake

The study of the factors that regulate high energy food intake is especially relevant nowadays due to the high prevalence of overweight and obesity. Food intake regulation can be divided in two basic processes, namely satiation and satiety. Satiation is the process that determines the moment in which feeding stops and regulates the amount of ingested food during a single meal. Satiety is the interval between meals and regulates the time elapsed between two meals. The longer the interval, the lower energy intake. Each of these processes are regulated by different factors, which are here reviewed.

Conducta alimentaria y estado nutricional: antes, durante y después del cáncer / EATING BEHAVIOR AND NUTRITIONAL STATUS: BEFORE, DURING AND AFTER CANCER

El objetivo de este artículo es presentar una clasificación para el estudio de las conductas alimentarias y el estado nutricional en el proceso de enfermedad del cáncer. Las conductas alimentarias son un factor que interviene en la aparición, progresión y tratamiento del cáncer, además de comprometer el estado nutricional de los individuos. La relación entre nutrición y cáncer es bidireccional: por un lado, una alimentación inadecuada puede aumentar la incidencia de determinados cánceres, así como alterar el estado nutricional de los pacientes que ya presentan la enfermedad, y por otro lado, el propio cáncer y sus tratamientos pueden inducir la aparición de problemas nutricionales que se presentan en un 40-80% de los pacientes en el curso de la enfermedad. Por esta relación se hace evidente la dependencia que existe entre conducta alimentaria y cáncer. Las conductas alimentarias pueden estudiarse en tres etapas: conducta alimentaria antes del cáncer, conducta alimentaria durante el cáncer y conducta alimentaria después de los tratamientos. Por tal motivo, la investigación acerca del estado nutricional de los pacientes y las conductas alimentarias que se manifiestan en este lapso es fundamental para conocer y evitar el aumento de la morbilidad y mortalidad de las personas por cáncer.
