RESUMO

Autism spectrum disorder (ASD) is a neurodevelopmental disorder defined as persistent difficulty in maturing the socialization process. Health professionals have used traditional methods in the therapies performed on patients with the aim of improving the expression of emotions by patients. However, they have not been sufficient to detect the different emotions expressed in the face of people according to different sensations. Therefore, different artificial intelligence techniques have been applied to improve the results obtained in these therapies. In this article, we propose the construction of an intelligent mirror to recognize five basic emotions: angry, scared, sad, happy and neutral. This mirror uses convolutional neural networks to analyze the images that are captured by a camera and compare it with the one that the patient should perform, thus supporting the therapies performed by health professionals in children with ASD. The proposal presents the platform and computer architecture, as well as the evaluation by specialists under the technology acceptance model.

RESUMO

La incidencia de individuos con Trastorno Espectro Autista (TEA) va en aumento. Por lo tanto, es importante la detección oportuna de la condición y conocer los factores de riesgo asociado a nutrición, en especial porque se trata de una población nutricionalmente vulnerable. Desde la última década, las investigaciones han aportado evidencia sobre los mecanismos que subyacen al TEA. Se ha comprobado la coexistencia de diversas complicaciones asociadas al TEA, tales como: trastornos metabólicos, deficiencias nutricionales y condiciones asociadas a la microbiota y funcionalidad gastrointestinal, que podrían estar relacionadas con la etiología o comportamiento en este grupo en particular. Es de suma importancia realizar un resumen de la evidencia con la finalidad de entregar información relacionada a los factores alimentarios y nutricionales asociados a modificación de comportamiento en TEA y desarrollo del mismo, para llevar a cabo una evaluación e intervención oportuna e individualizada, con un enfoque multidimensional, sistémico, multi e interdisciplinario.


The incidence of individuals with autism spectrum disorder (ASD) is increasing. Early detection of the condition and recognizing risk factors associated with nutrition is essential, mainly because this population is nutritionally vulnerable. In the last decade, research has provided evidence on the mechanisms underlying ASD. The coexistence of various complications associated with ASD, such as metabolic disorders, nutritional deficiencies, and conditions associated with the microbiota and its gastrointestinal functionality, have been proven to be related to the etiology of behavior in this particular group. Therefore, it is of utmost importance to summarize the evidence to provide information related to dietary and nutritional factors associated with behavior modification in ASD and to carry out a timely and individualized assessment and intervention, with a multidimensional, systemic, multi and interdisciplinary approach.

RESUMO

The purpose of this research was to analyze the eating patterns of preschool- and school-aged children with ASD, as provided by their families, in the La Araucanía Region of Chile. It involved a cross-sectional study with 72 families with children diagnosed with ASD aged between 2 and 12 years old. Food selectivity, appetite, body mass index (BMI) and frequency of food consumption were studied. The research determined that 97.67% present food selectivity, corresponding to alterations in the frequency of consumption of specific food groups. Moreover, 93.06%, 90.28%, 80.56% and 62.50% of children in the study do not meet the daily recommendations for fruit, fish, water and vegetable consumption, respectively. Therefore, it is important for these findings to be considered when designing and carrying out educational interventions regarding food in families with children with ASD for greater assertiveness and effectiveness in improving health.

RESUMO

BACKGROUND: The associations of cancer with types of diets, including vegetarian, fish, and poultry-containing diets, remain unclear. The aim of this study was, therefore, to investigate the association of type of diet with all cancers and 19 site-specific incident cancers in a prospective cohort study and then in a meta-analysis of published prospective cohort studies. METHODS: A total of 409,110 participants from the UK Biobank study, recruited between 2006 and 2010, were included. The outcomes were incidence of all cancers combined and 19 cancer sites. Associations between the types of diets and cancer were investigated using Cox proportional hazards models. Previously published prospective cohort studies were identified from four databases, and a meta-analysis was conducted using random-effects models. RESULTS: The mean follow-up period was 10.6 years (IQR 10.0; 11.3). Compared with meat-eaters, vegetarians (hazard ratio (HR) 0.87 [95% CI: 0.79 to 0.96]) and pescatarians (HR 0.93 [95% CI: 0.87 to 1.00]) had lower overall cancer risk. Vegetarians also had a lower risk of colorectal and prostate cancers compared with meat-eaters. In the meta-analysis, vegetarians (Risk Ratio (RR): 0.90 [0.86 to 0.94]) and pescatarians (RR 0.91 [0.86; 0.96]) had lower risk of overall and colorectal cancer. No associations between the types of diets and prostate, breast, or lung cancers were found. CONCLUSIONS: Compared with meat-eaters, vegetarians and pescatarians had a lower risk of overall, colorectal, and prostate cancer. When results were pooled in a meta-analysis, the associations with overall and colorectal cancer persisted, but the results relating to other specific cancer sites were inconclusive.

RESUMO

The Objective is to determine the stages of change in the behavior of university students regarding the purchase of ultra-processed snacks consumed. Multi-center study (14 Chilean universities). The participants (4,807 students)evaluated were applied a survey to determine the stage of change of behavior regarding the purchase of foods with warning signs. The students were evaluated and classified as (a) Nutrition Students, (b) Healthcare-related Students and (c) Other degree Students. More than 90% of the students were aware of the food regulation and knew the warning signs. More than 60% of Healthcare-related and Other degree students are in the stage of pre-contemplation or contemplation regarding purchase intent of sugary drinks, juices, cookies, sweet snacks and potato chips; this value is twice the percentage of Nutrition students in this stages ( Chi2, p<0.001). In conclusion there is a high proportion of pre-contemplation and contemplation with respect to purchase intent among the students(AU)


Determinar las etapas de cambio en el comportamiento de los estudiantes universitarios con respecto a la compra de colaciones ultraprocesadas. Estudio Multicéntrico (14 universidades chilenas). A los participantes (4.807 estudiantes) se les aplicó una encuesta para determinar el cambio en el comportamiento con respecto a la compra de alimentos con sellos de advertencia. Los estudiantes se clasificaron como (a) estudiantes de nutrición, (b) estudiantes del área de la salud y (c) estudiantes de otras carreras. Se evaluaron. Más del 90% de los estudiantes conocían la regulación alimentaria y conocían las señales de advertencia. Más del 60% de los estudiantes de la salud y de otras carreras se encuentran en la etapa de pre-contemplación o contemplación con respecto a la intención de compra de bebidas azucaradas, jugos, galletas, bocadillos dulces y papas fritas; Este valor es el doble del porcentaje de estudiantes de nutrición en estas etapas ( Chi2, p <0,001). Se concluye que existe una alta proporción de pre-contemplación y contemplación con respecto a la intención de compra entre los estudiantes universitarios(AU)

RESUMO

OBJECTIVE: To analyze the stage of change in food consumption with warning labels among Chilean university students. MATERIALS AND METHODS: Cross-sectional study which applied surveys in universities from all over the country. Study included 4807 participants of 18 to 40 years of both sexes who were asked about the level of knowledge of the new food law and food consumption with warning signals, including questions regarding their willingness to behavior change according to Prochaska's transtheoretical model. To compare continuous variables, Student's t-test was used in the statistical package SPSS 22.0, and p <0.05 was considered a significant difference. RESULTS: Of the total number of respondents, 99.3% of the students indicated that they know about the food law, classifying foods with signals in the precontemplation stage. Compared by sex, we observed that women give greater importance to behavior change in all of foods (p <0.001). Underweight students give less importance to change in unhealthy foods, while obesity students give more importance but do not show more confidence in behavior change (p <0.05). CONCLUSION: The university students show a low importance and confidence to make behavior change, aspects associated with sex and nutritional status. It is necessary to strengthen nutritional food education and not just talk about structural measures.
