Estudio de la interrelación de factores ambientales, dietéticos y genéticos que afectan a la obesidad infantil
2015
La obesidad tiene un origen multifactorial en el que existe una base genética, pero que requiere una serie de influencias ambientales para que se ponga de manifiesto. En ella influyen los factores dietéticos y de estilo de vida como el ejercicio físico, el estrés y los acontecimientos vitales. El gen del receptor de la melanocortina 4 (MC4R) es un buen candidato de análisis debido a su relación con la obesidad, su papel en la regulación de la ingesta de alimentos y el gasto energético. Por ello, el objetivo principal de este trabajo es estudiar si existe relación entre factores genéticos, antropométricos, de riesgo metabólico y cardiovascular y factores ambientales en una población infantil…
Associations of the FTO rs9939609 and the MC4R rs17782313 polymorphisms with type 2 diabetes are modulated by diet, being higher when adherence to th…

Background: Although the Fat Mass and Obesity (FTO) and Melanocortin-4 Receptor (MC4R) genes have been consistently associated with obesity risk, the association between the obesity-risk alleles with type 2 diabetes is still controversial. In some recent meta-analyses in which significant results have been reported, the associations disappeared after adjustment for body mass index (BMI). However gene-diet interactions with dietary patterns have not been investigated. Our main aim was to analyze whether these associations are modulated by the level of adherence to the Mediterranean Diet (MedDiet). Methods: Case-control study in 7,052 high cardiovascular risk subjects (3,430 type 2 diabetes c…
Statistical and biological gene-lifestyle interactions of MC4R and FTO with diet and physical activity on obesity: new effects on alcohol consumption
2012
Background: Fat mass and obesity (FTO) and melanocortin-4 receptor (MC4R) and are relevant genes associated with obesity. This could be through food intake, but results are contradictory. Modulation by diet or other lifestyle factors is also not well understood. Objective: To investigate whether MC4R and FTO associations with body-weight are modulated by diet and physical activity (PA), and to study their association with alcohol and food intake. Methods: Adherence to Mediterranean diet (AdMedDiet) and physical activity (PA) were assessed by validated questionnaires in 7,052 high cardiovascular risk subjects. MC4R rs17782313 and FTO rs9939609 were determined. Independent and joint associati…
