UNASSIGNED: The study population included 4,317 individuals 19 to 64 years of age who participated in the Korean National Health and Nutrition Examination Survey (KNHANES VII-3, 2019-2021). A food frequency questionnaire was used to evaluate prebiotic and probiotic food consumption. The Generalized Anxiety Disorder Assessment 7-item scale (GAD-7) assessed the severity of anxiety symptoms. The effect of prebiotic and probiotic food consumption on anxiety severity was analyzed using multiple logistic regression.
UNASSIGNED: Anxiety symptom severity was significantly lower in the highest prebiotic and/or probiotic food consumption tertiles compared to the lowest food consumption tertile. We also found a sex difference in the odds ratio for anxiety symptoms. The consumption of prebiotic food was significantly associated with the highest odds of anxiety among both men and women. However, probiotic food had a significant beneficial effect on lowering anxiety symptoms in men but not in women.
UNASSIGNED: Our finding suggests that prebiotic and probiotic food consumption might confer a beneficial influence on anxiety symptoms. Further research is required for a deeper understanding into the mechanisms of the positive effects of prebiotics and probiotics on anxiety.
■研究人群包括4,317名19至64岁的个人,他们参加了韩国国家健康和营养检查调查(KNHANESVII-3,2019-2021)。食物频率问卷用于评估益生元和益生菌食物的消耗。广泛性焦虑症评估7项量表(GAD-7)评估焦虑症状的严重程度。使用多元logistic回归分析了益生元和益生菌食物消费对焦虑严重程度的影响。
■与最低的食物消费三元相比,最高的益生元和/或益生菌食物消费三元的焦虑症状严重程度显着降低。我们还发现焦虑症状的比值比存在性别差异。在男性和女性中,益生元食物的消费与焦虑的几率最高显著相关。然而,益生菌食品对降低男性焦虑症状有显著的有益作用,但对女性没有。
■我们的发现表明,食用益生元和益生菌食物可能会对焦虑症状产生有益的影响。需要进一步的研究才能更深入地了解益生元和益生菌对焦虑的积极作用机制。
