At the Highland Park Hospital the increase in cesarean section rates has paralleled the national increase. Data from cesarean deliveries performed for cephalopelvic disproportion (a leading reason for cesarean section) in 1969 to 1972 (group 1) and 1979 to 1982 (group 2) were evaluated to determine maternal, fetal, and delivery factors that might be related to the increase in the rates. The data suggested that the more frequent diagnosis of cephalopelvic disproportion and the increased size of the group 2 infants were the primary reasons for the increase in cesarean section rate. This increased rate was paralleled by a decline in forceps-assisted delivery and in perinatal mortality rates.
在高地公园医院，剖宫产率的增长与全国的增长情况同步。对1969年至1972年（第1组）和1979年至1982年（第2组）因头盆不称（剖宫产的主要原因）进行剖宫产分娩的数据进行了评估，以确定可能与剖宫产率上升相关的母体、胎儿和分娩因素。数据表明，头盆不称诊断频率的增加以及第2组婴儿体型的增大是剖宫产率上升的主要原因。这种上升的比率伴随着产钳助产率和围产期死亡率的下降。
