Fear of childbirth during pregnancy may increase the risk of emergency cesarean section

Abstract

The purpose of our study was to elucidate the association between fear of childbirth, general anxiety, and stress coping during the third trimester of pregnancy, and a subsequent delivery by emergency cesarean section. In a case-control study, 1,981 Swedish-speaking women completed three self-assessment questionnaires at 32 weeks' gestation. Ninety-seven of these women were delivered by emergency cesarean section. Fear of childbirth, general anxiety and the stress coping ability of these 97 cases were compared with the same features in 194 controls, matched for age and parity. Women, subsequently delivered by emergency cesarean section, reported a greater anxiety and a poorer stress coping ability, and, most obviously, a greater fear of childbirth at 32 weeks' gestation. After elimination of possible confounders, the odds ratio for emergency cesarean section was examined for women whose scores were above various cut-off points according to the fear of childbirth measuring instrument. For women with a serious fear of childbirth the odds ratio was 3.0 (95% confidence interval 1.4 to 6.6), and the population attributable risk 0.167. Fear of childbirth during the third trimester of pregnancy may increase the risk of subsequent emergency cesarean section.
