The aetiology and consequences of ‘baby blues’ (lower mood following childbirth) are yet to be sufficiently investigated with respect to an individual's clinical history.

The primary aim of the study was to assess the symptoms of baby blues and the relevant risk factors, their associations with clinical history and premenstrual syndrome (PMS), and their possible contribution to the early recognition of postpartum depression (PPD).

Beginning shortly after childbirth, 369 mothers were followed up for 12 weeks. Information related to their clinical history, PMS, depression, stress and mother–child attachment was collected. At 12 weeks, mothers were classified as non-depressed, or with either PPD or adjustment disorder.

A correlation was found between the severity of baby blues and PMS (r = 0.397, P < 0.001), with both conditions increasing the possibility of adjustment disorder and PPD (baby blues: OR = 6.72, 95% CI 3.69–12.25; PMS: OR = 3.29, 95% CI 2.01–5.39). Baby blues and PMS independently predicted whether a mother would develop adjustment disorder or PPD after childbirth (χ2(64) = 198.16, P < 0.001). Among the non-depressed participants, baby blues were found to be associated with primiparity (P = 0.012), family psychiatric history (P = 0.001), PMS (P < 0.001) and childhood trauma (P = 0.017).

Baby blues are linked to a number of risk factors and a history of PMS, with both conditions adding to the risk of PPD. The neuroendocrine effects on mood need be understood in the context of individual risk factors. The assessment of both baby blues and PMS symptoms within the first postpartum days may contribute to an early identification of PPD.

Despite many signs and symptoms of depression get dismissed as normal physiologic changes associated with childbirth, depressive disorders are a common complication of pregnancy and postpartum period. The so-called “baby blues” have a minor functional impact and respond well to social support, whilst postpartum depression causes significant functional compromise, requiring more aggressive therapy. There is an extreme type of postpartum depressive disorder, postpartum psychosis, when patients present psychosis, mania, or thoughts of infanticide. It is imperative to promptly recognize and differentiate these entities, in order to minimize its impact on both mother and child. Antidepressant treatment may be necessary for some women, but risks and benefits should always be considered prior to institute pharmacotherapy.

To identify current approaches and evidence-based treatment options for postpartum depression.

Review of the most recent literature regarding postpartum depression. The research was carried out through the Cochrane, UptoDate, PubMed, MedLine, LILACS and SciELO databases, using the terms “postpartum depression”, “baby blues” and “postpartum psychosis”, until December 2020.

Since both depression and antidepressant medications confer risk upon the infant, when postpartum depression develops, psychotherapy is usually the first-line treatment. Antidepressant treatment may be necessary, but its use during pregnancy and postpartum must be weighed carefully.

In order to better prevent postpartum depression, recommendations include the use of screening instruments as a routine clinical practice during pregnancy and referral when necessary. Maternal depression has a severe impact on both mother and child, so mental health professionals have a very important role in reducing postnatal emotional complications.
