Abstract

Zinc is crucial for brain development and psychiatric regulation. In the present study, we investigated the relationship between cerebrospinal fluid (CSF) zinc level and anxiety in a group of male Chinese subjects. Results demonstrated that zinc levels had no considerable interindividual variations, ranging from 8.37 to 16.83µm. Correlation analyses revealed that CSF Zinc levels were positively correlated with education years (r=0.225, p=0.024) and negatively correlated with SAS scores (r=-0.287, p=0.004), but not associated with age or BMI. In conclusion, this present study suggests that CSF zinc level is associated with anxiety.
