It is well established that low breastfeeding self-efficacy is associated with early breastfeeding cessation. Over the past several decades, expressed human milk feeding has increased among parents of healthy infants. Researchers have hypothesized an association between maternal breastfeeding confidence and expressed human milk feeding, but it has not been empirically examined. Therefore, the primary objective of this study was to assess the associations between breastfeeding self-efficacy and human milk expression practices. The secondary objective was to assess the effect of breastfeeding self-efficacy on breastfeeding duration and exclusivity. This study used a prospective cohort design. From 2017 to 2018, we recruited 821 healthy mothers with term births in two public hospitals in Hong Kong. Participants completed a self-administered questionnaire in the immediate postpartum period, which gathered information about sociodemographic characteristics and Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF). Participants were followed up for 6 months or until infants were weaned. The proportion and type of infant feeding were assessed at telephone follow-up. The overall mean BSES-SF score in our sample was 46.5 (standard deviation = 10.1). Every one-point increase in the BSES-SF score was associated with 4-5% lower risk of any expressed human milk feeding and 4-7% higher odds of breastfeeding continuation across the first 6 months postpartum. Higher breastfeeding self-efficacy is associated with a lower risk of expressed human milk feeding and a longer duration of any and exclusive breastfeeding. Further studies should explore how improving breastfeeding self-efficacy may affect the mode of human milk feeding.
已证实，低母乳喂养自我效能与早期母乳喂养中断有关。在过去几十年中，健康婴儿的父母越来越多地采用表达母乳喂养。研究人员假设母亲母乳喂养信心与表达母乳喂养之间存在关联，但尚未进行实证检验。因此，本研究的主要目的是评估母乳喂养自我效能与母乳表达实践之间的关联。次要目的是评估母乳喂养自我效能对母乳喂养持续时间和排他性的影响。本研究采用前瞻性队列设计。2017 年至 2018 年，我们在香港的两家公立医院招募了 821 名足月分娩的健康母亲。参与者在产后立即完成一份自我管理的问卷，该问卷收集了社会人口特征和母乳喂养自我效能量表-短表（BSES-SF）的信息。参与者在 6 个月或直到婴儿断奶时进行随访。通过电话随访评估婴儿喂养的比例和类型。我们样本的总体平均 BSES-SF 得分为 46.5（标准差=10.1）。BSES-SF 得分每增加 1 分，任何形式的表达母乳喂养的风险就会降低 4-5%，产后前 6 个月母乳喂养持续的可能性就会增加 4-7%。较高的母乳喂养自我效能与表达母乳喂养的风险降低和任何形式的纯母乳喂养持续时间延长有关。进一步的研究应探讨如何提高母乳喂养自我效能可能会影响母乳喂养的模式。
