| Outline of Final Research Achievements |
Postpartum depression is a common disorder that occurs in approximately 5%-10% of pregnant women and has a negative impact not only on the affected mother but also on the child. This study aimed to establish molecular markers that allow detection of postpartum depression by performing metabolome analysis on prenatal and postnatal serum samples from perinatal pregnant subjects.
According to the Edinburgh postnatal depression scale, the subjects were divided into a nondepressive (ND) group, a postpartum depressive (PD) group, and a continuous depressive (CD) group.Principal component analysis revealed that the amino acid pattern in the PD group was different from that in the ND group. However, the PD group showed a pattern similar to that of the CD group. In the PD group, a correlation was found between the postpartum depression score and glutamic acid.These results demonstrate that the onset of postpartum depression may be predicted by examining the amino acid profile before childbirth.

| Academic Significance and Societal Importance of the Research Achievements |
本検討により産前のトリプトファン代謝やアミノ酸プロファイルを検討する事で、産後の抑うつ病態の発症が予測できる可能性が示唆されたことから、広く臨床に貢献できる検討であると考えられる。
