In today's modem obstetrics, perinatal morbidity and mortality of mother and neonate have become extremely rare. Despite these advances, are pregnant women still afraid of childbearing and, if so, what - and how intense - are their fears? Are these fears influenced by previous birthing experiences and by birth preparation classes? Data from more than 8000 expectant mothers (collated via a prenatal questionnaire distributed between Novemeber 1, 1991 and October 31, 1999) are evaluated. This study examines and discusses the answers concerning quantity and quality of childbirth-related fear among women of differing parity and its possible relation to attended birth preparation classes. The women delivered in a hospital setting that practices modem obstetrics combined with alternative delivery methods. The most frequent fears mentioned are fear for the child's health (50%) and fear of pain (40%). Fears dealing with medical intervention, such as operative deliver) anesthesia, nerve blockage and of being at the mercy of obstetrics all lie at around 12%. It is difficult to establish a clear-cut benefit of birth preparation classes in reducing childbirth fears.
