Prenatal case histories and labours of 908 mothers who delivered prematurely at the University of Heidelberg, Department of Gynaecology and Obstetrics in Mannheim, between the years 1966-1971 were compared with a freely selected group of 782 mothers who delivered healthy mature infants with birth weights over 2500 g. (Premature infants -- under 2501 g; Stillborn infants -- under 2501 g and a minimum 35 cm crown-heel length). A tendency to premature delivery was observed in primipara, multipara with at least 4 previous deliveries, unmarried mothers, and in women with a preceding miscarriage or with closely spaced pregnancies less than 24 months apart. Bleeding during pregnancy, EPH-Syndrome, inadequate prenatal care, premature amnion rupture, abruptio placentae, pathological presentation and complications during labour were more frequently observed in mothers who delivered prematurely than those at full term. Histo-pathological changes of the placentas were found in 11,2% in cases of premature births as opposed to 3,6% in full term cases.
对1966年至1971年间在曼海姆海德堡大学妇产科早产的908名母亲的产前病史和分娩情况，与随机挑选的782名分娩健康成熟婴儿（出生体重超过2500克）的母亲进行了比较。（早产儿——体重低于2501克；死产儿——体重低于2501克且顶臀长度至少35厘米）。初产妇、至少有4次既往分娩史的经产妇、未婚母亲以及有过流产史或妊娠间隔小于24个月的女性中观察到早产倾向。早产母亲比足月母亲更频繁地出现孕期出血、妊娠高血压综合征、产前护理不足、胎膜早破、胎盘早剥、胎位异常和分娩期并发症。早产病例中11.2%的胎盘有组织病理学改变，而足月病例中这一比例为3.6%。
