Adverse life experiences are associated with an increased risk of mental disorders. The successful adaptation to adversity and maintenance or quick restoration of mental health despite adversity is referred to as resilience. Identifying factors that promote resilience can contribute to the prevention of mental disorders. Lifestyle behaviors, increasingly recognized for their impact on mental health, are discussed as potential resilience factors. Several studies found that healthy eating and physical activity (PA) are positively associated with resilience. However, most of these studies assessed resilience through questionnaires, which is unsatisfactory given that resilience research is moving toward conceptualizing resilience as the outcome of a dynamic process, which can only be assessed prospectively and longitudinally. The present study is the first to assess the relationship between diet quality, PA, sedentary behavior (SB), and resilience, captured prospectively and longitudinally in a sample of 145 individuals (75.17% female; Mage = 28.88, SDage = 7.80; MBMI = 24.11, SDBMI = 3.97). Resilience was assessed as the relationship between stressor exposure and mental health (i.e., the stressor reactivity score: higher scores indicate lower resilience and vice versa). Diet quality (i.e., the Healthy Eating Index) was assessed on the basis of app-based food records and 24-hr dietary recalls. PA and SB were objectively recorded through accelerometers. Regression analysis showed that neither diet quality nor PA and SB predicted resilience (ps > .30). Profound differences in the conceptualization and operationalization of resilience might explain the contrary findings. Prospective longitudinal studies are needed to replicate the findings of the present study. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

克服逆境还是咬紧牙关？饮食质量、身体活动和久坐行为与恢复力的关系。


不良的生活经历与精神障碍的风险增加有关。在逆境中成功适应逆境并保持或快速恢复心理健康被称为复原力。确定促进心理恢复力的因素有助于预防精神障碍。生活方式行为因其对心理健康的影响而日益得到认可，被讨论为潜在的弹性因素。几项研究发现，健康饮食和身体活动 （PA） 与恢复力呈正相关。然而，这些研究中的大多数通过问卷调查来评估弹性，这并不令人满意，因为弹性研究正朝着将弹性概念化为动态过程的结果，这只能前瞻性和纵向地进行评估。本研究首次评估了饮食质量、PA、久坐行为 （SB） 和恢复力之间的关系，前瞻性和纵向捕获了 145 个个体的样本（75.17% 为女性;法师 = 28.88，SDage = 7.80;MBMI = 24.11，SDBMI = 3.97）。弹性被评估为压力源暴露与心理健康之间的关系（即压力源反应性评分：分数越高表示弹性越低，反之亦然）。饮食质量（即健康饮食指数）是根据基于应用程序的食物记录和 24 小时饮食回忆进行评估的。通过加速度计客观记录 PA 和 SB。回归分析显示，饮食质量以及 PA 和 SB 均无法预测恢复力 （ps > .30）。韧性的概念化和操作化的深刻差异可能解释了相反的发现。需要前瞻性纵向研究来复制本研究的结果。 （PsycInfo 数据库记录 （c） 2024 APA，保留所有权利）。
