Extremely preterm infants often receive donor milk. Hindmilk, which is released more than 3 minutes after letdown, could be advantageous due to its elevated levels of fat and calorie density. Donor milk expression habits may influence milk composition but have not yet been investigated. This study aims to assess the practices of milk donors and the feasibility of hindmilk expression. Active milk donors in Québec were questioned using an online survey about their milk expression habits and whether hindmilk donation would be acceptable to them. Answers were analyzed using mixed methods. Of 181 donors, 126 fully completed the questionnaire (70%); 57% reported expressing donated milk between breastfeeds; 15% reported simultaneously breastfeeding while expressing donated milk from the other breast; 12% reported breastfeeding their baby on each breast, then expressing donated milk (hindmilk). The majority (66%) would be willing to change their habits most or all the time to provide hindmilk for preterm infants. The main themes invoked by respondents in open-ended answers were altruism and gratitude for being able to help others. However, 15% commented on the complexity of milk expression or that adding further complexity might discourage them from donating. Expression practices are variable, which may lead to variability in donor milk composition. Most donors would agree to change their expression habits in favor of giving hindmilk to help the most fragile infants. More information is needed on how changing recommendations for milk expression might impact the supply and composition of donor milk.
极早产儿常接受捐赠母乳。射乳反射 3 分钟后分泌的后奶，脂肪和热量密度较高，可能具有优势。捐赠母乳的挤出习惯可能会影响母乳成分，但尚未进行研究。本研究旨在评估母乳捐赠者的实践情况，以及挤出后奶的可行性。
通过在线问卷调查，询问魁北克的活跃母乳捐赠者有关其母乳挤出习惯，以及他们是否愿意捐赠后奶。使用混合方法分析回答。在 181 名捐赠者中，126 名（70%）完整填写了问卷；57%的人报告在母乳喂养之间挤出捐赠母乳；15%的人报告同时母乳喂养，同时从另一个乳房挤出捐赠母乳；12%的人报告每次母乳喂养一个乳房，然后挤出捐赠的母乳（后奶）。大多数（66%）愿意最多或全部时间改变习惯，为早产儿提供后奶。受访者在开放式回答中提到的主要主题是利他主义和感激之情，因为他们能够帮助他人。然而，15%的人评论了母乳挤出的复杂性，或认为增加更多的复杂性可能会使他们不愿意捐赠。挤出习惯存在差异，这可能导致捐赠母乳成分的差异。大多数捐赠者愿意改变他们的挤出习惯，以提供后奶来帮助最脆弱的婴儿。需要更多关于改变母乳挤出建议如何影响捐赠母乳的供应和成分的信息。
