This was a nurse-driven, hospital-based, prospective cohort study of data collected in 19 hospitals in San Bernardino and Riverside counties by California Perinatal Services Network on all mothers (n = 21 842) who delivered a singleton infant (37-40 weeks gestation) between July 2005 through June 2006. Multivariate ordinal logistic regression showed that maternal infant-feeding method intention (measured prior to birth), sociodemographic characteristics, intrapartum variables, and early skin-to-skin mother-infant contact during the first 3 hours following birth (controlling for delivery hospital) were correlated with exclusive breastfeeding during the maternity hospitalization. Compared with mothers with no early skin-to-skin contact, exclusive breastfeeding was higher in mothers who experienced skin-to-skin contact for 1 to 15 minutes (odds ratio [OR] 1.376; 95% confidence interval [CI], 1.189-1.593), 16 to 30 minutes (OR 1.665; 95% CI, 1.468-1.888), 31 to 59 minutes (OR 2.357; 95% CI, 2.061-2.695), and more than 1 hour (OR 3.145; 95% CI, 2.905-3.405). The results demonstrate a dose-response relationship between early skin-to-skin contact and breastfeeding exclusivity.
这是一项由护士主导、基于医院的前瞻性队列研究，数据来自加利福尼亚围产期服务网络在圣贝纳迪诺县和里弗赛德县的 19 家医院收集，研究对象为 2005 年 7 月至 2006 年 6 月期间分娩单胎婴儿（37-40 周妊娠）的所有母亲（n=21842）。多变量有序逻辑回归显示，产妇母乳喂养方法意向（在分娩前测量）、社会人口统计学特征、分娩期间的变量以及分娩后最初 3 小时内的早期母婴皮肤接触（控制分娩医院）与产妇住院期间的纯母乳喂养相关。与没有早期皮肤接触的母亲相比，皮肤接触 1-15 分钟（比值比 [OR] 1.376；95%置信区间 [CI] 1.189-1.593）、16-30 分钟（OR 1.665；95% CI 1.468-1.888）、31-59 分钟（OR 2.357；95% CI 2.061-2.695）和超过 1 小时（OR 3.145；95% CI 2.905-3.405）的母亲，纯母乳喂养的比例更高。研究结果表明，早期母婴皮肤接触与母乳喂养的专一性之间存在剂量反应关系。
