Antenatal depression, substance dependency and social support

Background: The purpose of this study was to explore the prevalence of depression and factors associated with depressive mood among pregnant women. Method: 391 women who were 14–37 weeks pregnant were evaluated with the Edinburgh Postnatal Depression Screen (EPDS), which has also been validated for prenatal use. Four questionnaires were used in order to explore associated factors: a questionnaire on background and pregnancy data, the Substance Abuse Subtle Screening Inventory (SASSI) and two Social Support Questionnaires (SSQ1 and 2). Results: 7.7% of the total sample screened positive on the EPDS with a cut-off point of 12/13 recommended. Substance dependency and experienced difficulties in social environment had an independently significant association with maternal depression. Limitation: The caseness was defined with a self-report instrument. Conclusion: Substance dependency and experienced difficulties, especially in relation to friends, partner and own mother, are associated with antenatal depression. It is important to be aware of this when developing interventions in maternity care primary units.
