Distortion of self-image: risk factor for obesity in children and teenagers

Introduction: Self-image is important in the behaviour and lifestyle of children and adolescents. Analysing the self-image they have and the factors that might influence their distortion, can be used to prevent problems of obesity and anorexia. The main objective of present publication was to analyse the risk factors that may contribute to self-image distortion. Material and Methods: A descriptive survey study was conducted among 659 children and adolescents in two social classes (low and medium-high), measuring height and weight, calculating BMI percentile for age and gender. Body image and self-perception were registered. Results: The percentage of overweight-obesity is higher in scholars (41.8% boys, 28.7% girls) than in adolescents (30.1% and 22.2% respectively), with no difference between socioeconomic classes. The multinomial logistic regression analysis gives a risk of believing thinner higher (p=0.000) among boys OR=2.9(95%CI:1.43-3.37), school (p=0.000) OR=2.42(95%CI:1.56-3.76) and much lower (p=0.000) between normally nourished OR=0.08(95%CI:0.05-0.13), with no differences according to socioeconomic status. The risk of believing fatter is lower (p=0.000) between boys OR=0.28(95%CI:0.14-0.57), school(p=0.072) OR=0.54(95%CI:0.27-1.6), and much higher among underweight (p=0.000) OR=9x108(95% CI:4x108-19x108). Conclusions: Are risk factors of believing thinner: males, being in a group of schoolchildren and overweight-obesity. Conversely, are risk factors of believing fatter: females, teen and above all, be thin.

Idiopathic Adolescent Scoliosis: Living with a Physical Deformity

A qualitative, phenomenological, hermeneutical study with the aim of explaining the experience of having a body deformity diagnosed as idiopathic adolescent scoliosis. A semistructured interview conducted with scoliosis patients admitted to the unit of spinal cord at the Vall d’Hebron Hospital was used. The youth defined their scoliosis based on how they perceived their deformity. They spoke of pain and deformity as characteristic symptoms of suffering, and explained how this symptom affected their social relationships. Their deformity was associated with words such as “horrible”, “shame”, “complex” and “problem.” It is concluded that the symptommost referred is pain and the biggest concern of the youth was their body aesthetic and feelings associated with it. They attempt to solve this problem by adapting the way they dress and through surgery. Surgery can resolve the body deformity but not self-perception of their body image.

Calibración de cámaras de tiempo de vuelo: ajuste adaptativo del tiempo de integración y análisis de la frecuencia de modulación

La percepción de profundidad se hace imprescindible en muchas tareas de manipulación, control visual y navegación de robots. Las cámaras de tiempo de vuelo (ToF: Time of Flight) generan imágenes de rango que proporcionan medidas de profundidad en tiempo real. No obstante, el parámetro distancia que calculan estas cámaras es fuertemente dependiente del tiempo de integración que se configura en el sensor y de la frecuencia de modulación empleada por el sistema de iluminación que integran. En este artículo, se presenta una metodología para el ajuste adaptativo del tiempo de integración y un análisis experimental del comportamiento de una cámara ToF cuando se modifica la frecuencia de modulación. Este método ha sido probado con éxito en algoritmos de control visual con arquitectura ‘eye-in-hand’ donde el sistema sensorial está compuesto por una cámara ToF. Además, la misma metodología puede ser aplicada en otros escenarios de trabajo.

Life Experiences of People Affected by Crohn’s Disease and Their Support Networks Scoping Review

This scoping review identifies and describes relevant studies related to the evidence published on life experiences and perceived social support of people affected by Crohn’s disease. Twenty-three studies were definitely selected and analyzed for the topics explored. The overall findings show patients’ needs and perceptions. There is a lack of evidence about patients’ perceived needs as well as the understanding of social support that has contributed to improve their life experiences with that chronic illness. Lack of energy, loss of body control, body image damaged due to different treatments and surgeries, symptoms related to fear of disease, feeling burdened loss related to independence, and so on are some of the concerns with having to live with those affected by the Crohn. To underline those experiences through this scoping review provides valuable data for health care teams, especially for the nursing profession, considered by those affected as one of the main roles along the whole pathological process. This review provides the basis for developing broader research on the relatively underexplored topics and consequently improves specific programs that could address patients’ needs.

Gestión del tratamiento dietético cuali-cuantitativo en el sobrepeso y la obesidad: metodología y una nueva perspectiva de asesoramiento individualizado

%WL: porcentaje de pérdida de peso; %FL: porcentaje de pérdida de grasa. Objetivo: describir la metodología en la gestión del tratamiento dietético cuali-cuantitativo en el sobrepeso y la obesidad. Método: se llevaron a cabo 4.625 consultas con 616 pacientes mayores de 25 años con sobrepeso y obesidad, en el sur-este de España, durante los años 2006-12. Se utilizó una dieta equilibrada, hipocalórica, cuali-cuantitativa con alimentos de la zona. Se describió la metodología del tratamiento dietético en la pérdida y el mantenimiento. Se trató qué unidades de medida son adecuadas para la expresión del éxito en la pérdida; una nueva visión del asesoramiento individualizado y el tratamiento multidisciplinar. Resultados: el 80% de los pacientes obtienen un %FL ≥ 5% (22,6 ± 11,8 - 11,2 ± 7,4), y asistieron a la consulta más de mes y medio. Conclusión: se presenta un esquema de la metodología del tratamiento dietético; se han recomendado las unidades de medidas a utilizar en consulta y en la publicación de ensayos clínicos, creando un precedente con grado de evidencia de cómo determinar la pérdida exitosa; se recomienda medir los perímetros de cadera y cintura, e incorporar el estudio de la imagen corporal; se presenta una nueva visión del asesoramiento individualizado y una atención multidisciplinar avanzada, independiente de la edad, el estado de gestación y las minusvalías físicas. La postura del sanitario debe de ser considerada como el gestor encargado de determinar qué técnicas podrían ser más efectivas en dicha pérdida.
