Rates of breast-feeding were studied in collectives of 998 mothers (Dortmund) and 500 mothers (Haltern) in two large maternity wards encouraging breast-feeding. In both hospitals the collectives were representative for the population in the surrounding region. Mothers were asked to take part in the study as they were admitted. Response rates were 99%. Age and parity of mothers in Dortmund were in agreement with population statistics, whereas in the Haltern collective there was a smaller proportion of younger mothers. The collective in Haltern had a slight edge with respect to social background. The different types of delivery had the same percentages in both wards. Birthweight was on the average 100 g higher in Haltern neonates. There were no differences in mean length. In both wards feeding on demand was practised during the rooming-in period during daytime, whereas at night infants were bottle-fed on demand in the infant's room. In Haltern supplementary formula feeding was offered more liberally. In Dortmund 92%, in Haltern 97% of the mothers tried to breast-feed; only 5% and 2% respectively were unsuccessful. Mothers who did not want to breast-feed (8% and 3% respectively) rarely mentioned relevant obstacles as a reason for their decision. On discharge 80-90% of the mothers were breast-feeding, with only about one half of them fully breast-feeding. Caesarean section was hardly detrimental to initiation of breast-feeding, but often to success.
在两个大力提倡母乳喂养的大型产科病房中，对多特蒙德的998名母亲和哈尔滕的500名母亲群体的母乳喂养率进行了研究。在这两家医院中，这些群体都代表了周边地区的人口情况。母亲们在入院时被邀请参与研究，回应率为99%。多特蒙德母亲的年龄和胎次与人口统计数据相符，而在哈尔滕群体中，年轻母亲的比例较小。哈尔滕的群体在社会背景方面略占优势。两个病房中不同分娩类型的比例相同。哈尔滕新生儿的平均出生体重比多特蒙德的高100克，平均身长没有差异。在两个病房中，日间母婴同室期间都实行按需喂养，而夜间婴儿在婴儿室按需进行奶瓶喂养。在哈尔滕，补充配方奶喂养更为宽松。在多特蒙德，92%的母亲尝试母乳喂养，在哈尔滕为97%；分别只有5%和2%的尝试未成功。不想母乳喂养的母亲（分别为8%和3%）很少提及相关障碍作为其决定的原因。出院时，80 - 90%的母亲进行母乳喂养，其中只有约一半完全母乳喂养。剖宫产对母乳喂养的开始影响不大，但对母乳喂养的成功影响较大。
