An Italian nationwide presentation of data concerning the proportion of births by caesarean section (CS) for the period 1980-1985 is presented here. A constant increase in CS was noted, from 11.2% in 1980 to 15.8% in 1985. The increase was observed in all regions while higher rates were noted in northern and central Italy. CS rates are higher in older age groups, in pregnancies from 29th to 35th week of gestation for high and low birthweights and malpresentations. Ecological associations revealed that CS is positively related to economic development and negatively to perinatal and stillbirth rates.
本文展示了意大利全国范围内1980 - 1985年剖宫产（CS）分娩比例的数据。剖宫产率持续上升，从1980年的11.2%升至1985年的15.8%。所有地区均出现了这种增长，而意大利北部和中部的剖宫产率更高。年龄较大的年龄组、妊娠29至35周、出生体重高和低以及胎位异常的孕妇剖宫产率更高。生态关联显示，剖宫产与经济发展呈正相关，与围产儿和死产率呈负相关。
