Abstract:
:Background: Anxiety disorders in youth are attributable to multiple causal mechanisms, comprising biological vulnerabilities, such as genetics and temperament, and unfavourable environmental influences, such as childhood maltreatment (CM). Objective: A gene-environment (G x E) interaction study was conducted to determine the interactive effect of the BDNF Val66Met polymorphism and CM to increase susceptibility to anxiety sensitivity (AS) in a sample of mixed race adolescents. Method: Participants (n = 308, mean age = 15.8 years) who were all secondary school students and who completed measures for AS and CM were genotyped for the BDNF Val66Met polymorphism. Hierarchical multiple regression analysis was conducted to assess G x E influences on AS. Age and gender were included in the models as covariates as age was significantly associated with AS total score (p < .05), and females had significantly higher AS scores than males (p < .05). Results: A main effect of CM on AS was evident (p < .05), however, no main effect of BDNF genotype on AS was observed (p > .05). A non-significant G x E effect on AS was revealed (p < .05). Conclusions: Our results suggest that CM does not have a moderating role in the relationship between the BDNF Val66Met genotype and the increased risk of anxiety-related phenotypes, such as AS. Given the exploratory nature of this study, findings require replication in larger samples and adjustment for population stratification to further explore the role of BDNF Val66Met and CM on AS in mixed race adolescents. :Antecedentes: los trastornos de ansiedad en los jóvenes son atribuibles a múltiples mecanismos causales, que comprenden vulnerabilidades biológicas, como la genética y el temperamento; y las influencias ambientales desfavorables, como el maltrato infantil (MI). Objetivo: Se realizó un estudio interacción gen-ambiente (GxA) para determinar el efecto interactivo del polimorfismo Val66Met del BDNF y MI para aumentar la susceptibilidad para la sensibilidad a la ansiedad (SA) en una muestra de adolescentes de raza mixta.Método: los participantes (n=308, Edad Media:15.8 años) que fueron todos estudiantes de secundaria que completaron las medidas para SA y MI, fueron genotipificados para el polimorfismo Val66Met del BDNF. Se realizó un análisis de regresión múltiple jerárquica para evaluar las influencias GxA en SA. La edad y género se incluyeron como covariables en los modelos, ya que la edad se asoció significativamente con el puntuación total SA (p<0.05), y las mujeres tuvieron puntuaciones de SA significativamente mayores que los hombres (p<0.05).Resultados: Un efecto principal de MI en SA fue evidente (p<0.05), sin embargo, no se observó ningún efecto principal del genotipo BDNF en SA (p>0.05). Se reveló un efecto GxA No significativo sobre SA (p<0.05).Conclusiones: Nuestros resultados sugieren que MI no tiene un rol moderador en la relación entre el genotipo Val66Met del BDNF y el mayor riesgo de fenotipos relacionados con la ansiedad, como SA. Dada la naturaleza exploratoria de este estudio, los hallazgos requieren la replicación en muestras más grandes y el ajuste de la estratificación de la población para explorar más a fondo el rol de Val66Met del BDNF y MI en SA en adolescentes de raza mixta. :背景:青年时期的焦虑症可归因于多种因果机制,包括生物学上的易感性(如遗传和气质); 和不利的环境影响,如童年虐待(CM)。目的:分析基因-环境(G×E)相互作用研究以确定BDNF Val66Met多态性与CM在混合种族青少年样本中增加对焦虑敏感性(AS)的易感性的交互作用。方法:被试(n = 308,平均年龄:15.8岁)都是中学生,并完成了AS和CM测量,进行了BDNF Val66Met多态性的基因型分类。进行层级多元回归分析以评估G×E对AS的影响。 年龄和性别作为协变量包括在模型中,因为年龄与AS总分显著相关(p <0.05),女性AS评分显著高于男性(p <0.05)。结果:CM对AS有明显主效应(p <0.05),但BDNF基因型对AS的主效应没有观察到(p> 0.05), 说明了GxE对 AS的影响不显著(p <0.05)。结论:我们的研究结果表明,CM没有调节BDNF Val66Met基因型与焦虑相关表型(如AS)风险增加之间的关系。 鉴于本研究的探索性质,研究结果需要在更大的样本中重复,并调整人群分层,以进一步探索在青少年混合种族样本中BDNF Val66Met和CM对AS的作用。.
