To evaluate exclusive breastfeeding at discharge and hospital length-of-stay in preterm infants undergoing or not the Kangaroo-Mother Care Method (KMC). A retrospective cohort study was conducted including preterm infants < 1800 g admitted to the neonatal unit of a KMC reference center. The infants were grouped into the KMC group and the non-KMC group. Multiple logistic and Poisson regressions were performed to evaluate the association between the KMC and two outcomes, exclusive breastfeeding at discharge, and hospital length-of-stay, adjusted for potential confounders. 115 mother-infant dyads were included, 78 in the KMC group and 37 in the non-KMC group. In the bivariate analysis, the KMC group had a lower prevalence of maternal adverse conditions (6% vs. 32%, < 0.001), a higher number of prenatal visits (median 6 vs. 3.5, < 0.001), higher gestational ages (median 32 vs. 31 weeks, < 0.05), higher birth weights (median 1530 vs. 1365 g, < 0.01), a lower prevalence of necrotizing enterocolitis (3.8% vs. 16.2%, < 0.05), parenteral nutrition (50% vs. 73%, < 0.05), and deep vascular access (49.7% vs. 78.4%, < 0.01), a higher prevalence of exclusive breastfeeding (65% vs. 8%, < 0.001) and a shorter length of hospital stay (median 28 vs. 42 days, < 0.001). In the multiple regression analysis, the KMC group was 23 times more likely to be exclusively breastfed at discharge (OR = 23.1; 95% CI = 4,85–109,93) and had a 19% reduction in the hospital length-of-stay (IDR = 0.81; 95% CI = 0.76–0.86) compared to the non-KMC group. The KMC is associated with better short-term neonatal outcomes and should be encouraged in all Brazilian maternity hospitals.

巴西袋鼠妈妈护理参考中心的纯母乳喂养和早产儿住院时间

评估是否接受袋鼠妈妈护理法 (KMC) 的早产儿出院时纯母乳喂养和住院时间。进行了一项回顾性队列研究，纳入 KMC 参考中心新生儿病房收治的 < 1800 g 早产儿。将婴儿分为KMC组和非KMC组。我们进行了多重逻辑回归和泊松回归，以评估 KMC 与两种结果（出院时纯母乳喂养和住院时间）之间的关联，并针对潜在的混杂因素进行了调整。纳入 115 名母婴二人组，其中 78 名属于 KMC 组，37 名属于非 KMC 组。在双变量分析中，KMC 组孕产妇不良状况发生率较低（6% vs. 32%，< 0.001），产前检查次数较多（中位数 6 vs. 3.5，< 0.001），孕龄较高（中位数32 周与 31 周，< 0.05），出生体重较高（中位数 1530 与 1365 克，< 0.01），坏死性小肠结肠炎患病率较低（3.8% 与 16.2%，< 0.05），肠外营养（50% 与 16.2%，< 0.05）。 73%，< 0.05），深血管通路（49.7% vs. 78.4%，< 0.01），纯母乳喂养率较高（65% vs. 8%，< 0.001），住院时间较短（中位 28与 42 天相比，< 0.001)。在多元回归分析中，KMC 组出院时纯母乳喂养的可能性高出 23 倍（OR = 23.1；95% CI = 4,85–109,93），并且住院时间缩短了 19%。与非 KMC 组相比，停留时间（IDR = 0.81；95% CI = 0.76–0.86）。 KMC 与更好的短期新生儿结局相关，应该在巴西所有妇产医院得到鼓励。
