A random sample of 617 primiparas was identified from birth notifications over a 12 month period and 534 of these were interviewed four weeks after confinement. Those breast feeding at the time of interview were contacted again at four months and those still breast feeding then were contacted at six and a half months. Duration of breast feeding was found to be significantly associated with five interassociated personal characteristics of the mother and with specific aspects of her knowledge and attitudes regarding breast feeding. In hospital the timing of the first breast feed and difficulties with subsequent feeds, were important indicators; while at home the use of additional formula feeds was associated with a reduced prevalence of breast feeding by 18 weeks. A combination of older maternal age at confinement and older age at leaving school showed a tenfold increase of prevalence rates in breast feeding at 16 weeks between groups of mothers. The use of these two factors alone may thus help doctors, midwives, and health visitors in assessing the risk of premature termination of breast feeding and in planning programmes of preventive care.
在12个月的时间段内，从出生通知中随机抽取了617名初产妇样本，其中534名在分娩四周后接受了访谈。在访谈时进行母乳喂养的产妇在四个月时再次被联系，而那些那时仍在母乳喂养的产妇在六个半月时被联系。结果发现，母乳喂养的持续时间与母亲的五个相互关联的个人特征以及她对母乳喂养的知识和态度的具体方面显著相关。在医院里，首次母乳喂养的时间和后续喂养的困难是重要指标；而在家中，额外使用配方奶喂养与18周时母乳喂养普及率的降低有关。分娩时母亲年龄较大和离校年龄较大这两个因素相结合，使得不同组母亲在16周时母乳喂养普及率之间出现了十倍的增长。因此，仅使用这两个因素可能有助于医生、助产士和健康访视员评估母乳喂养过早终止的风险，并规划预防保健方案。
