The role of good nutrition for resilience in the face of stress is a topic of interest, but difficult to study. A 7.1 earthquake took place in the midst of research on a micronutrient treatment for Attention-Deficit/Hyperactivity Disorder (ADHD), providing a unique opportunity to examine whether individuals with ADHD taking micronutrients demonstrated more emotional resilience post-earthquake than individuals with ADHD not taking micronutrients. Thirty-three adults with ADHD were assessed twice following the earthquake using a measure of depression, anxiety and stress also completed at some point pre-earthquake (baseline). Seventeen were not taking micronutrients at the time of the earthquake (control group), 16 were (micronutrient group). While there were no between-group differences one week post-quake (Time 1), at two weeks post-quake (Time 2), the micronutrient group reported significantly less anxiety and stress than the controls (effect size 0.69). These between group differences could not be explained by other variables, such as pre-earthquake measures of emotions, demographics, psychiatric status, and personal loss or damage following the earthquake. The results suggest that micronutrients may increase resilience to ongoing stress and anxiety associated with a highly stressful event in individuals with ADHD and are consistent with controlled studies showing benefit of micronutrients for mental health.
营养对压力下韧性的作用是一个备受关注的话题,但很难进行研究。在一项针对注意缺陷多动障碍(ADHD)的微量营养素治疗的研究过程中,发生了 7.1 级地震,这为研究提供了一个独特的机会,以检验服用微量营养素的 ADHD 患者在地震后是否比未服用微量营养素的 ADHD 患者表现出更强的情绪韧性。地震发生后,33 名成年人接受了两次评估,使用一种评估抑郁、焦虑和压力的方法,该方法也在地震前的某个时间点(基线)完成。其中 17 人在地震发生时未服用微量营养素(对照组),16 人(微量营养素组)。虽然两组在地震后一周(时间 1)没有差异,但在两周(时间 2)后,微量营养素组报告的焦虑和压力明显低于对照组(效应大小为 0.69)。这些组间差异不能用其他变量来解释,如地震前的情绪、人口统计学、精神状态以及个人在地震后的损失或损害。结果表明,微量营养素可能会增加 ADHD 患者对与高度压力事件相关的持续压力和焦虑的适应能力,这与控制研究中显示微量营养素对心理健康有益的结果一致。
