About this study

To elucidate the disease pathway of perinatal depression by identifying genetic variants which could play a role in predisposing to the condition and/or lead to better understanding of the pathogenesis of the condition. This is achieved by investigating for associations between oestrogen receptor genetic variants and perinatal depression.

Read the detailed description

Perinatal (antenatal and postnatal) depression is a common complication of childbearing, affecting 10 to 20% of mothers. In general, women are exposed to fluctuations in estrogen level during childbearing years, especially during pregnancy and following childbirth. For a subgroup of women with genetic predisposition rendering them more sensitive to such changes, pregnancy or childbirth can act as a trigger for the onset of perinatal depression.

A case control study will be conducted to evaluate the association of variants in estrogen receptor and related genes with the disorder in our population. Women attending antenatal and postnatal clinics will be screened with the Edinburgh Postnatal Depression Scale and cases will be identified. DNA from controls who are well throughout the antenatal and postpartum period and cases meeting DSM IV criteria for depressive disorder will be genotyped for various genetic variants. The distribution of single nucleotide polymorphisms and haplotypes and non-genetic risk factors will be compared between cases and controls and within the case group. The risk factors for postnatal depression in relation to peripartum factors such as demographic, obstetric, anaesthetic and pain outcomes will be investigated.

As perinatal depression is known to contribute to inadequate self-care and poor compliance with prenatal care, early diagnosis and treatment interventions are critical for the health and well-being of both mother and infant. In the short term, identified genetic markers that increase vulnerability to puerperal triggering of depression can be an additional screening tool to identify at-risk expectant mothers for early management during a very critical period for mother, infant, and family. In the long run, it may lead to identification of new pathways or treatment targets for this common but under-studied disorder.

Study groups in NCT02373709
Study groupRoleWhat they receive
Cases: Perinatal depressionCases will be defined as those with a depressive episode with onset during the antenatal or postnatal period.
Controls: No perinatal depressionControls will be defined as those who score < 7 on Edinburgh Postnatal Depression Scale and/or no episode of clinical depression from pregnancy until 6 months postnatal.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Perinatal depression

    Defined as meeting Diagnostic and Statistical Manual for Psychiatric Disorders, Fourth Edition (DSM-IV) criteria for major depression through an interview by a clinician using Structured Clinical Interview for Diagnosis (SCID).

    Measured: Antenatal and postnatal period

Questions about this trial

What is this clinical trial studying?

An observational study of Postnatal Depression and Genetic Predisposition, run by KK Women's and Children's Hospital at 1 site in Singapore.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 26 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Perinatal depression (time frame: Antenatal and postnatal period). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Nov 2024.
