Questionnaires were sent to 1025 female board-certified obstetricians, and information was retrieved about pregnancy outcome. A total of 454 pregnancies, one third of which occurred during residency, were evaluated, and the relationship between pregnancy outcome and residency was assessed. Children of primiparous women who were delivered during or after residency had significantly lower mean birth weights than those who were delivered before residency (p less than 0.001 and p less than 0.005, respectively), whereas birth weights of infants born to multiparous women were not significantly different. The low birth weight rate (less than 2500 gm) was significantly increased during residency (p less than 0.002), and infants born during residency were 7.5 times more likely to be growth retarded than those born outside residency (p less than 0.002). The incidence of other pregnancy complications was not found to be increased during residency. Our data suggest a potentially negative impact of residency on the birth weights of infants born to female obstetricians in training.
问卷被发送给1025名获得委员会认证的女性产科医生，并收集了有关妊娠结局的信息。总共评估了454次妊娠，其中三分之一发生在住院医师培训期间，并评估了妊娠结局与住院医师培训之间的关系。初产妇在住院医师培训期间或之后分娩的孩子，其平均出生体重显著低于在住院医师培训之前分娩的孩子（分别为p<0.001和p<0.005），而经产妇所生孩子的出生体重没有显著差异。住院医师培训期间低出生体重率（低于2500克）显著增加（p<0.002），住院医师培训期间出生的婴儿生长发育迟缓的可能性是住院医师培训之外出生婴儿的7.5倍（p<0.002）。未发现住院医师培训期间其他妊娠并发症的发生率增加。我们的数据表明，住院医师培训可能会对接受培训的女性产科医生所生婴儿的出生体重产生负面影响。
