Perinatal anxiety

Perinatal anxiety is very common.  In a recent Australian study, one-fifth of women assessed during late pregnancy and reviewed at 2, 4 and 6–8 months after the birth had an anxiety disorder (approximately two-thirds with co-occurring depression) and almost 40% of women with a major depressive episode had a co-occurring anxiety disorder.

There are a number of different types of anxiety disorders.

The most common conditions that arise in pregnancy or after birth are detailed below:

Common anxiety disorders in the perinatal period

Antenatal anxiety may occur in response to fears about aspects of the pregnancy (e.g. parenting role, miscarriage, congenital disorders) or as a continuation of a pre-pregnancy condition and/or comorbidly with depression.  Higher levels of self-reported anxiety or anxiety disorder in pregnancy increase the risk of depression postnatally.

Anxiety disorders can have significant effects on the health and wellbeing, not only of the mother but also her partner and other children.  The latest research also reveals that anxiety disorders can have a negative impact on the growth and development of the foetus/baby, so early detection and intervention is paramount.

In many instances, anxiety symptoms are not recognised, as they are often viewed in the context of pregnancy or adjusting to the baby. In addition, high levels of stigma may prevent women seeking help.

Symptoms of perinatal anxiety

There are many types of anxiety disorders. While the symptoms of perinatal anxiety disorders are different, women who have symptoms of an anxiety disorder may experience:

  • anxiety or fear that interrupts thoughts and interferes with daily tasks
  • panic attacks — outbursts of extreme fear and panic that are overwhelming and feel difficult to bring under control
  • anxiety and worries that keep coming into the woman’s mind and are difficult to stop or control
  • constantly feeling irritable, restless or “on edge”
  • having tense muscles, a “tight” chest and heart palpitations
  • finding it difficult to relax and/or taking a long time to fall asleep at night
  • anxiety or fear that stops the woman going out with her baby
  • anxiety or fear that leads the woman to check on her baby constantly.

The psychosocial question on “worrying” and Questions 3, 4 and 5 of the EPDS reflect some of these symptoms.

Assessing women for perinatal anxiety

Assessing women for possible perinatal anxiety involves considering their answer to the psychosocial question on “worrying” and identifying possible symptoms using Questions 3, 4 and 5 of the Edinburgh Postnatal Depression Scale (EPDS).

About the EPDS

The EPDS is a questionnaire developed to assist in identifying symptoms of depression.  It is also useful in identifying symptoms of anxiety.  The EPDS is not a diagnostic tool; rather it aims to identify women who may benefit from follow-up care, such as mental health assessment, which may lead to a diagnosis based on accepted diagnostic criteria (DSM-IV-TR or ICD-10).

Translated versions of the EPDS have been validated in some languages.

How often should the EPDS be completed

All women should complete the EPDS at least once, preferably twice, in both the antenatal period and the postnatal period (ideally 6–12 weeks after the birth).

The non-diagnostic nature of the EPDS, its purpose and the fact that it relates to the previous 7 days (not just that day) should be clearly explained.

When follow-up care is required

Follow-up for further assessment for anxiety disorders may be needed if a woman’s answer to the psychosocial question (link to psychosocial questions) on “worrying” or her scores on Questions 3, 4 and 5 suggest possible symptoms of anxiety.

When is follow-up care required for anxiety disorders?

Note: Follow-up is also needed if the total score is 13 or more or if a woman has a positive score on Question 10 (self-harm).

Management of perinatal anxiety

Support and early intervention for women experiencing distress or anxiety symptoms may help to prevent more serious mental health problems from developing.  Depending on the severity of a woman’s symptoms, management of perinatal anxiety may involve a combination of psychosocial support, psychological therapy and pharmacological treatment.  Appropriate responses to assessments and clinical judgement are fundamental to decision-making about management.

Psychosocial support

Psychosocial interventions used as preventive approaches or as part of management of anxiety includes non-directive counselling, psychoeducation and peer support.

Women may also benefit from being given information about options for support in their communities (e.g. parent education groups, support groups, playgroups) and suggestions for where to seek practical support with tasks like cooking, cleaning and taking care of the baby, or any older children (e.g. family, friends, neighbours or community services).

Psychological therapies

The range of psychological therapies that are effective in treating anxiety disorders at times other than in the perinatal period would also be expected to be effective in the perinatal period, as the disorders differ little from disorders among non-pregnant women in both their presentation and course.

Pharmacological treatments

During pregnancy, use of selective serotonin reuptake inhibitors (SSRIs) can be considered, as there is no evidence for a consistent pattern of birth defects.  Tricyclic antidepressants (TCAs) can also be considered, especially if they have been effective previously, but should be used with caution due to the risk of overdose.

Both SSRIs and TCAs can also be safely used during breastfeeding.

Short-term use of short-acting benzodiazepines may be considered while awaiting onset of action of SSRIs.

More detail on the safety and effectiveness of pharmacological treatments is included in the National Perinatal Mental Health Guideline developed by COPE.

Guidelines for the use of antidepressants and benzodiazepines in the general population should be consulted.

Things to remember…

Some things to remember when assessing and managing anxiety in the perinatal period are:

  • Although the EPDS was specifically developed to detect symptoms of depression, there is evidence to support its use in the detection of symptoms of anxiety, taking into consideration the woman’s scores on questions 3, 4 and 5, her answer to the psychosocial question on “worrying” and applying clinical judgement.
  • While the EPDS is a self-report tool, it may be appropriate for it to be administered verbally in situations where there are difficulties relating to language or literacy, cultural issues or disability.
  • Before the EPDS is administered, women need clear explanation of the purpose of the assessment (including that it is part of normal care and will remain confidential) so that they can provide informed consent. If a woman does not consent to assessment, this should be documented and assessment offered at subsequent consultations.
  • Decision-making about the need for and type of follow-up mental health care is based on the woman’s preferences and clinical judgement.
  • Not all women will want or need further monitoring or mental health assessment. Providing information and encouraging continuing contact with an appropriate health professional can support women to seek further assistance.
  • Ideally, a woman’s regular GP will provide continuing mental health care in the perinatal period. However, not all women have access to this type of care or choose it when it is available. Assist women to identify a health professional with the skills, knowledge and cultural competence to provide appropriate ongoing care.
  • Continuity of care is an important aspect of effective care. It is important to document all assessments and share relevant information with the next health professional providing care to the woman (eg midwife passes information to maternal and child health nurse).
  • To access Medicare counselling items, a GP needs to provide a letter of referral for pregnancy support counselling or develop a mental health treatment plan with the woman for more formalised mental health treatment.  The GP then refers to a mental health care professional either through the Better Access or perinatal ATAPS Medicare programs.
