目的探讨焦虑学生的肠道菌群与焦虑的相关性以及在实施营养干预后肠道菌群的变化情况。方法利用双盲法进行营养干预,检测干预前后肠道菌群的变化。结果干预后,实验组的焦虑分数下降75%,双歧杆菌、乳酸菌、大肠杆菌、肠球菌与对照组比较统计学上均无显著性差异。结论焦虑能使肠道双歧杆菌和乳酸菌减少,大肠杆菌和肠球菌增多,营养干预能减轻焦虑,促进肠道菌群恢复正常。
Objective To investigate the correlation between intestinal microflora and anxiety in anxiety students and the change of intestinal microflora after nutritional intervention. Methods Nutritional intervention by double-blind method was used to detect the changes of intestinal flora before and after intervention. Results After intervention, the anxiety score of the experimental group decreased by 75%. There was no statistically significant difference between Bifidobacterium, Lactobacillus, Escherichia coli, Enterococcus and control group. Conclusion Anxiety can reduce intestinal bifidobacteria and lactic acid bacteria, Escherichia coli and enterococci increased, nutritional intervention can reduce anxiety and promote intestinal flora returned to normal.
