Records from 6820 deliveries of three year (1980, 1985 and 1988) were reviewed in order to collect informations on cesarean section trend and its indications in a public hospital of Milan, Italy. Data show the magnitude of the phenomenon in the wards considered and an evident increase of cesarean section proportion from 1980 (18.6%) to 1988 (26.9%). The frequencies of major indications has not changed much apart from dystocia which has decreased and previous cesarean section which has increased. A logistic regression model was performed to evaluate cesarean section risk factors. Distribution of cesarean section during the days of the week show higher (about 30%) cesarean section proportion Monday through Thursday compared with low proportion (20% or less) on Fridays and weekend-days; this suggesting a possible high proportion of pre-programmed cesarean section.
为了收集意大利米兰一家公立医院剖宫产趋势及其指征的信息，我们回顾了三年（1980年、1985年和1988年）6820例分娩记录。数据显示了所考虑病房中该现象的规模，以及剖宫产比例从1980年的18.6%到1988年的26.9%有明显增加。除难产比例下降和既往剖宫产比例增加外，主要指征的频率变化不大。进行了逻辑回归模型以评估剖宫产的危险因素。一周中各天的剖宫产分布显示，周一至周四的剖宫产比例较高（约30%），而周五和周末的比例较低（20%或更低）；这表明可能有较高比例的计划性剖宫产。
