Assim, o estudo teve como objetivo verificar a associação entre excesso de peso corporal e consumo de refrigerante em adolescentes escolares estratificado por sexo. Trata-se de um estudo transversal, realizado com estudantes do ensino médio. Utilizou-se um questionário autoaplicável. A variável desfecho foi a mediana do escore de IMC (eutrófico e excesso de peso) e o consumo de refrigerante foi a variável de exposição principal. Foi utilizado o modelo de Poisson, estratificado por sexo. Participaram do estudo 1.225 adolescentes, 53,4% do sexo feminino e 15,6% consumiam refrigerante diariamente. Nos adolescentes eutróficos não houve associação de consumo de refrigerantes e zIMC. Nos meninos com excesso de peso e consumo de refrigerante mais de duas vezes na semana apresentaram maior chance de estarem acima da mediana de zIMC. Os resultados apontaram que o consumo diário de refrigerantes por adolescentes do sexo masculino com excesso de peso pode aumentar as chances de ter zIMC ainda mais alto, reforçando assim, a necessidade de medidas que visem a redução do consumo de refrigerante.\u0000\u0000Adolescence is a period of several changes, with changes related to nutrition, which can result in excess body weight. Thus, the study aimed to verify the association between excess body weight and soft drink consumption in school adolescents stratified by sex. This is a cross-sectional study, carried out with high school students. A self-administered questionnaire was used. The outcome variable was the median BMI score (eutrophic and overweight) and soft drink consumption was the main exposure variable. The Poisson model, stratified by sex, was used. The sample consisted of 1,225 adolescents, which 53.4% were female and 15.6% consumed soft drinks daily. In eutrophic adolescents, there was no association between consumption of soft drinks and the BMI Z-score. In overweight boys and soda consumption more than twice a week, they were more likely to be above the BMI Z-score median. The results showed that the daily consumption of soft drinks by overweight male adolescents may increase the chances of having even higher BMI Z-score, thus reinforcing the need for measures aimed at reducing the consumption of soft drinks.","PeriodicalId":8390,"journal":{"name":"Archivos Latinoamericanos De Nutricion","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45743116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Por tal motivo, es de vital importancia la identificación de factores relacionados con el desarrollo y establecimiento de preferencias alimentarias en etapas tempranas de la vida y brindar recomendaciones que faciliten su adopción. Esta revisión sistemática de la literatura tiene como objetivo resumir la evidencia existente sobre los factores asociados a formar y modelar las preferencias alimentarias en etapas tempranas de la vida. Para esto se realizó una búsqueda en PubMed de estudios que evaluaran la asociación entre la exposición prenatal y posnatal de sabores, introducción temprana de alimentos y habituación al sabor dulce, alimentación complementaria y diversidad dietética. Se incluyeron artículos publicados desde el 2000 hasta el 2019. Resultados de 39 artículos sugieren que la alimentación durante los primeros dos años de vida y el desarrollo de preferencias alimentarias en etapas tempranas de la vida tiene el potencial de modificar los patrones de alimentación y establecerse en etapas posteriores de la vida, por lo que, los primeros mil días de vida constituyen una ventana de oportunidad para formar preferencias alimentarias saludables y mejorar la calidad de dieta de los niños.\u0000\u0000Poor diets are damaging children’s health. Therefore, it is urgent to identify factors related to the development and establishment of healthy food preferences early in life and to provide recommendations to enable their adoption. This systematic literature review aims to summarize the existing evidence on the factors identified on shaping food preferences early in life. For this, a search was conducted on PubMed about studies evaluating the association between prenatal and postnatal exposure of flavors and the development of food preferences, early food introduction, innate preference to sweet taste, complementary feeding and dietary diversity with the development of food preferences. Articles published from 2000 to 2019 were included. Results from 39 manuscripts suggest that the first 2 years of life are critical for the development of food preferences early in life. These food preferences have the potential to modify children’s eating patterns and persist later in life. Therefore, the first 1000 days of life are a key window of opportunity to establish healthy food preferences and shape the quality of children’s diet.","PeriodicalId":8390,"journal":{"name":"Archivos Latinoamericanos De Nutricion","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43634238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsequently, titles and abstracts were read to filter the articles. Of the 3585 results found, 10 articles were selected with protocols of 3 to 4 weekly training sessions of 15 to 60 minutes, with interventions of 4 to 12 weeks. All types of training were beneficial for anthropometric and biochemical improvement, only resistance training (RT) has a significant difference for muscle mass compared to aerobic training (AT). Even though of the small number of studies with this type of comparison, it is still unclear which type of training is better or whether the two done concurrently would be a better alternative. According to our findings adolescents who want to maximize the effect of exercise on anthropometric variables should ideally perform aerobic and endurance exercises, but significant benefit can be achieved through any type of exercise, and if it were to have a significant differentiation within muscle mass the resistance exercise may be ideal to achieve this goal.\u0000\u0000En este artículo de revisión, fue analizado cual es el método de entrenamiento que es más efectivo para adolescentes con obesidad, de allí, a que nuestro objetivo en esta revisión es definir cual de los protocolos de entrenamiento (aeróbico, de resistenciao combinado) es mas apropiado para mejorar la composición corporal y otros factores asociados con la obesidad en adolescentes.

In terms of mango production, Manila´s variety represents a quarter of the total mangoes production in Mexico. However, the changes that occur on the phenolic compounds during the Manila mango ripening process are unknown. Quantitative analysis of the major phenolic compounds was conducted at different maturity stages, using several spectrophotometric measurements and by high-performance liquid chromatography (HPLC). At the late ripening stage was observed the biggest content in pulp and peel of total phenols (577 and 10547 mg EAG /100 g), flavonoids (95.33 and 537 mg EQ/100 g), and antioxidant capacity by DPPH (25 and 347 mmol TE/100 g). Some bioactive compounds achieve their highest values at optimal consumption ripening. Although they diminish when the fruit reaches a senescence appearance. This is the first study to prove that mangiferin by itself shows a higher correlation in antioxidant capacity compared to other phenolic compounds in mango peel, and this suggest that phenolic compounds may have an important role in the postharvest antioxidant metabolism in Manila mango fruit. On the other hand, the results show that the peel compared to the pulp contains higher amounts of total phenols, flavonoids, gallic acid, mangiferin and antioxidant capacity, so its use as an ingredient in the preparation of functional food products is recommended. More studies are needed to go in-depth in the changes of the content of phytochemicals during the ripening process in the peel and pulp mango, which ones could be caused by the hormones responsible for ripening in the fruit, such as ethylene, and bioavailability of these compounds at different stages of maturation.\u0000\u0000El mango es la segunda fruta tropical más comercializada del mundo y México es el principal exportador.

Methodology: A cross-sectional study was conducted with 384 adolescents aged 17 and 18 years. The nutritional status was evaluated through the BMI. The quality of the diet was evaluated through the Revised Diet Quality Index (IQD-R). The inflammatory markers used were C-Reactive Ultrasensitive Protein (hs-CRP), IL-6 (Interleukin-6) and TNF-α (Tumor Necrosis Factor α). Multivariate analysis was performed using a decision tree using the CART (Classification and Regression Trees) algorithm to evaluate the relationship between BMI, diet quality and inflammatory markers. Results: The mean age was 17.3±0.5 years, predominance of females (56.5%) and eutrophic (69.3%). The mean IQD-R score was 55.3±12.7. Adolescents in the lowest tertile of IQD-R (T1) had a higher mean BMI (22.1±4.3 kg/m2 vs 21.5 ± 3.7kg/m2). Higher levels of IL-6 were observed in those located on the IQD-R T1 (1,345 mg/L vs 1,205 mg/L). In the same group (T1), adolescents who had higher IL-6 levels also had a higher mean BMI (23.6±5.1kg/m2 vs 20.8±3.0kg/m2).

En humanos, se han reportado diferencias interindividuales en los umbrales de deteccion y preferencia del sabor dulce, lo que podria afectar la ingesta habitual de azucares, y por ende al estado nutricional. Objetivo: El presente estudio busca determinar la relacion entre el estado nutricional y la preferencia al sabor dulce en la comunidad de un establecimiento de educacion superior. Metodo: Muestra fue constituida por estudiantes, funcionarios y docentes, entre 18 y 60 anos, pertenecientes a la Universidad Mayor, Sede Temuco. Para determinar preferencia al sabor dulce se empleo prueba organoleptica que mide grado de satisfaccion frente a solucion dulce, junto a ello se realizaron mediciones de peso y talla para determinar el Indice de Masa Corporal. Resultados: Muestra final comprendio de 319 personas, de las cuales un 30,1% fueron hombres y 69,9% mujeres. No se observaron diferencias significativas en la preferencia hacia las soluciones con mayor concentracion de sacarosa segun el estado nutricional. Sin embargo, el modelo predictivo desarrollado arrojo que hombres prefieren las soluciones con mayor concentracion de azucar independiente de la edad y estado nutricional. Conclusiones: Es necesario desarrollar nuevos estudios que permitan aclarar si la preferencia al sabor dulce favorece el desarrollo de obesidad y sobrepeso, o si es la composicion nutricional de los alimentos procesados o ultraprocesados, lo que esta teniendo un mayor impacto negativo en el estado nutricional de la poblacion. The dramatic increase in the prevalence and incidence of obesity seems to suggest that environmental factors and lifestyle changes are contributing significantly to the epidemic trend of this pathology. In humans, inter-individual differences in the thresholds of preference of sweet taste have been reported, which could affect habitual sugar intake, and therefore the nutritional status. Objective: The present study seeks to determine the relationship between nutritional status and the preference of sweet taste in the population of a higher education establishment. Method: Sample was constituted by students, officials and teachers between 18 and 60 years, belonging to the Universidad Mayor, Temuco. To determine the perception of the sweet taste, an organoleptic test was used that measures the degree of satisfaction with the sweet solution, along with this, weight and height measurements were made to determine the Body Mass Index.
