Human milk diet, preferably mother's own milk (MOM) over donor milk (DM), is recommended for preterm infants. Expression of MOM in proximity to preterm infants, especially during or immediately after skin-to-skin contact (SSC), is associated with greater milk production. However, the correlation between SSC and MOM production during hospital admission in preterm infants has not yet been studied. Our study investigated the relationship between SSC and MOM production and consumption in preterm infants during the first postnatal month of life. This was a prospective cohort study. Mothers and their preterm infants born at <35 weeks by gestational age (GA) and eligible for SSC within the first 5 postnatal days were eligible for the study. Mothers were given a binder to document pumped breast milk volumes and SSC sessions. Pumped breast milk volumes, enteral feeding type and volume, and SSC duration and frequency were collected daily over the first 28 days of life, along with demographic, perinatal, and feeding data from electronic medical records (EMR). Mean birth GA and weight were 30 ± 3 weeks and 1,443 ± 576 g, respectively. SSC duration was inversely correlated with GA and weight. The SSC duration was positively correlated with ingested MOM volume after correcting for birth GA. The SSC duration was predictive of increased volumes of pumped MOM. Our findings suggest that SSC duration is associated with improved MOM production and consumption. SSC can be a useful tool to increase MOM exposure and improve long-term health outcomes in preterm infants.
人乳喂养，最好是母亲的自有母乳（MOM）而非捐赠母乳（DM），推荐用于早产儿。在早产儿附近表达 MOM，特别是在皮肤接触（SSC）期间或之后立即，与更大的乳汁产量相关。然而，SSC 与早产儿在医院住院期间的 MOM 产量之间的相关性尚未得到研究。我们的研究调查了在早产儿生命的第一个产后月期间 SSC 与 MOM 产量和消耗之间的关系。 这是一项前瞻性队列研究。符合条件的母亲及其胎龄（GA）<35 周且在出生后第 5 天内有资格进行 SSC 的早产儿均有资格参加研究。母亲们被给予一个束带以记录泵出的母乳量和 SSC 会议。在生命的前 28 天内，每天收集泵出的母乳量、肠内喂养类型和量以及 SSC 持续时间和频率，以及从电子病历（EMR）收集人口统计学、围产期和喂养数据。 平均出生 GA 和体重分别为 30±3 周和 1443±576 克。SSC 持续时间与 GA 和体重成反比。在校正出生 GA 后，SSC 持续时间与摄入的 MOM 量呈正相关。SSC 持续时间可预测泵出 MOM 量的增加。 我们的研究结果表明，SSC 持续时间与 MOM 产量和消耗的增加有关。SSC 可以是一种有用的工具，可以增加早产儿对 MOM 的暴露，并改善其长期健康结果。
