Scenario

Mental health awareness in pregnancy was emphasised during an obstetrics continual professional development event. The speaker summarised adverse perinatal outcomes that has been linked with maternal depression. A midwife asked, “Does depression in dads have similar impact on these outcomes?”

Description of research

Participants Singleton births recorded in the Medical Birth Register of Sweden between 2007–2012
Intervention Parents with depression
Comparison Parents without depression
Outcomes Odds ratios (ORs) for very preterm and moderately preterm births
Study design A population-based cohort study
Authors’ conclusion New paternal and maternal prenatal depression are potential risk factors for preterm birth

Discussion Points

  • How common is paternal depression in the perinatal period? (See suggested reading)
  • What are the risk factors of parental depression identified in this study?
  • How was parental depression defined in this study? What are the pros and cons of using this definition?
  • What is Huber-White sandwich estimates of variance? Was its use appropriate?
  • What were the relationships between paternal depression, spontaneous preterm births and medically-indicated preterm births?
  • How was cohabitation of parents related to preterm birth rates?
  • What are the possible mechanisms behind the above associations?
  • How do the demographics of the study participants compare to parents you encounter in your usual practice? (See Table 1–2)
  • How may the results of this study influence your daily practice?

The discussion points are attached below (quoted from the published manuscript)

Scenario

A 35-year-old nulliparous woman with depression consulted you for pre-conception advice. Her depression had been well-controlled by fluoxetine (Prozac), a selective serotonin reuptake inhibitor, for over 5 years. She had no other medical conditions. She asked, ‘Is Prozac going to affect my baby’s development?’

Description of research

Participants Norwegian women who were pregnant between 1999 and 2008
Intervention Self-reported use of selective serotonin reuptake inhibitors (SSRIs) during pregnancy
Comparison No reported use of SSRIs during pregnancy
Outcomes Language competence of their children at age three by maternal evaluation on a language grammar rating scale
Study design Population-based prospective cohort study

Discussion Points

  • Are you aware of other published studies addressing a similar clinical question?
  • Critically appraise and comment on this paper using the Critical Appraisal Skills Programme (CASP) checklist for cohort studies (http://bit.ly/1e0eF1n).
  • How was the use of SSRIs ascertained in this study? How could you reduce any potential bias from using this method?
  • How does language competence at three years correlate with long-term linguistic performance?
  • What are the advantages and disadvantages of using language competence by maternal evaluation at 3 years as the primary outcome measure?
  • Were the patient reported outcome measures (PROMs) used in this study chosen appropriately? (See PROM group, Oxford University: http://phi.uhce.ox.ac.uk/inst_selcrit.php)
  • Can you briefly summarise the results of this study? How would the results of this study influence your practice? (Data S1)
