Estudio de la variación a largo plazo de los parámetros bioquímicos metabólicos en pacientes con obesidad mórbida e intervenidos mediante bypass gást…

2015

INTRODUCCIÓN La Obesidad es ya uno de los mayores problemas de salud pública en los países occidentales y se prevé que en un futuro cercano sea una verdadera epidemia. La naturaleza de este problema no es estética, como es habitual que se valore en nuestro entorno social. Tiene un sinfín de repercusiones. Empezando por las comorbilidades metabólicas que la acompañan, las complicaciones osteoarticulares que desencadena o simplemente el rechazo social que muchas veces genera. Todo ello sumado, da lugar a una pérdida importante de esperanza de vida y de la calidad de la misma. La consecuencia fundamental de la Obesidad y que provoca el mayor riesgo de morbilidad y, sobre todo de mortalidad, es…

Potential role of branched-chain amino acid catabolism in regulating fat oxidation.

2013

Insulin-resistant or obese individuals have increased serum branched-chain amino acid (BCAA) levels. Recent findings relate increased BCAA catabolism to increased fatty acid oxidation and better metabolic health in physically active individuals. We hypothesize that, via glyceroneogenesis, BCAA catabolism mediates increased constitutive use of fatty acids for β-oxidation in subjects with increased inherent or acquired aerobic capacity both during exercise and at rest.

Sugar reduction: Stevia rebaudiana Bertoni as a natural sweetener

2020

Abstract Excessive sugar consumption is associated with the development of numerous health problems, such as obesity and many chronic diseases (e.g., cardiovascular disease, diabetes). Obesity is a rapidly growing public health problem, thus its prevention and treatment are crucial to improve the quality of life. Among others, sugar-sweetened beverage consumption was considered as a key risk factor that contributes to a significant excess of sugar in the diet. The World Health Organization is intensively working on strategies to reduce sugar intake by featuring educational methods and innovative marketing techniques for various communities, media, governments, and industries. Despite many s…

Normal-weight obesity and cardiometabolic risk : A 7-year longitudinal study in girls from prepuberty to early adulthood

2017

Objective: To study whether normal-weight obesity in childhood is associated with increased cardiometabolic risk in early adulthood. Methods: This study assessed data for 236 girls followed from prepuberty to early adulthood. Growth chart data were obtained from birth to 18 years. Body composition was assessed by dual-energy x-ray absorptiometry and cardiometabolic risk by calculating continuous clustered risk score (at ages 11, 14, and 18). The association of body weight status with cardiometabolic risk from childhood to early adulthood was examined. Results: Subjects with normal-weight obesity were virtually indistinguishable from their normal-weight lean peers in terms of relative body w…

Estudio de la relación entre los hábitos de vida, las variaciones del ritmo circadiano y los trastornos metabólicos en la obesidad infantil

2022

Numerosos estudios realizados en trabajadores del turno de noche evidencian una relación entre la alteración de los ritmos circadianos y los trastornos metabólicos. En paralelo, otras investigaciones realizadas principalmente en modelos animales o en adultos humanos, muestran una relación entre los hábitos de vida, la duración insuficiente y la mala calidad del sueño, y el desarrollo de la obesidad y sus comorbilidades. Sin embargo, se sabe poco sobre el papel que desempeñan estos mecanismos en la actual epidemia de obesidad infantil. Por ello, desarrollamos un estudio de la relación entre los hábitos de vida, los ritmos circadianos de la melatonina y el metabolismo, en el contexto de la ob…

Does weight status increase vulnerability to the food environment?

2022

Obesity is an important public health issue with socioeconomic consequences. Its origin is multifactorial, with environmental, biological, psychological and social dimensions. Furthermore, its consequences involve physical, psychological and social complications on an individual level. The main tool employed to categorize individuals according to their weight status is the body mass index (BMI). This indicator, based on the ratio of weight to height, is used to define what constitutes a "normal" weight status (between 18.5 and 24.9 kg/m 2), overweight (between 25 and 29.9 kg/m 2), and obesity (30 kg/m 2 and above). Current approaches to tackling obesity target a number of actors in the food…

Metformin Use and Cognitive Function in Older Adults With Type 2 Diabetes Following a Mediterranean Diet Intervention

2021

Background and Purpose: Both adherence to the Mediterranean diet (MedDiet) and the use of metformin could benefit the cognitive performance of individuals with type 2 diabetes, but evidence is still controversial. We examined the association between metformin use and cognition in older adults with type 2 diabetes following a MedDiet intervention. Methods: Prospective cohort study framed in the PREDIMED-Plus-Cognition sub-study. The PREDIMED-Plus clinical trial aims to compare the cardiovascular effect of two MedDiet interventions, with and without energy restriction, in individuals with overweight/obesity and metabolic syndrome. The present sub-study included 487 cognitively normal subjects…

BARDET-BIEDL SYNDROME – CASE PRESENTATION

2015

Bardet-Biedl syndrome (autosomal-recessive inheritance) is characterized by obesity, retinal dystrophy, polydactyly and mental retardation. The authors emphasize the necessary steps in order to establish the diagnosis for an infant with overweight, polydactyly and hypo-genitalism.

Convenience Behavior and Being Overweight in Adults: Development and Validation of the Convenience Behavior Questionnaire

2019

The etiology of overweight and obesity is a mixture of genetic determinants, environmental factors, and health behaviors. Especially intra- and interpersonal inactive behaviors, here termed convenience, seems to play an important role. The objective was to develop and validate the Convenience Behavior Questionnaire (CBQ) to assess convenience-related items and their association with overweight and obesity in a large population. A sample of 1233 subjects aged 18–82 years from six population groups took part in a self-administered questionnaire. Test-retest reliability was estimated and the independent association between convenience-related items and overweight and obesity was investigated. …
