A sample of 38 white working class primiparas intending to breast feed were alternately assigned to either an experimental or control group during the last trimester of pregnancy. All women were visited at home antenatally for a structured interview on their attitudes towards and information on breast feeding. The experimental group were visited twice before the birth, seen within the first 5 days in hospital, and visited immediately after they returned home, to enable the provision of information, advice and support regarding breast feeding. All women were seen again at 3 months postpartum. There was a significant difference between the two groups in level of breast feeding success, and explanations for this effect are put forward in terms of the experimental intervention components.
选取了38名打算进行母乳喂养的白人工人阶级初产妇样本，在她们怀孕的最后三个月被交替分配到实验组或对照组。所有女性在产前都在家中接受了关于她们对母乳喂养的态度和相关信息的结构化访谈。实验组在分娩前接受了两次家访，在住院的头5天内接受探视，并在她们回家后立即进行家访，以便提供关于母乳喂养的信息、建议和支持。所有女性在产后3个月时再次接受检查。两组在母乳喂养成功率方面存在显著差异，并从实验干预因素的角度对这种效果给出了解释。
