ObjectivesTo investigate the obstetric and psychological characteristics of women who opt to use epidural analgesia (EDA) during labour and the impact of participating in labour preparation courses on women's decisions to use EDA.DesignLongitudinal cohort study.SettingAkershus University Hospital, Norway.Population2596 women with singleton pregnancies and intended vaginal delivery.MethodsData were collected using two self-completed questionnaires at pregnancy weeks 17 and 32. Fear of childbirth was assessed by the Wijma Delivery Expectancy Questionnaire (W-DEQ). Symptoms of anxiety were measured by the Hopkins Symptom Check List (SCL-25) and depression by the Edinburgh Postnatal Depression Scale (EPDS). Obstetric and socio-demographic information was retrieved from birth records at the maternity ward.Main Outcome MeasurePreference for EDA was indicated by the questionnaire item "I would prefer an epidural regardless" on a 4-point scale (1 = highly agree, 4 = highly disagree) at pregnancy week 32.ResultsTwenty-one percent of the women (540/2596) answered that they would choose EDA as the only alternative method of analgesia during labour. Counselling for fear of childbirth [OR 3.23 (95%CI 2.12; 4.92)] and W-DEQ sum score ≥ 85 [OR 2.95 (95%CI 2.06; 4.23)] were significantly (p<0.001) associated with choice of EDA. Participation in labour preparation courses was significantly (p = 0.008) associated with a reduction of intended use of EDA during labour [OR 0.67 (95%CI 0.49; 0.90)].ConclusionFear of childbirth is significantly associated with women's choice of EDA during labour. On the other hand, women that participate in labour preparation courses would rather consider other methods of analgesia during labour.
