BackgroundBreast milk is the optimal method of human nutrition, and donor human milk is often needed to reduce the incidence of necrotizing enterocolitis and septicemia in preterm infants and improve their survival rate. Donor human milk is recommended as the first alternative when mothers’ milk is not available. The establishment of human milk banks is of great significance to promote the breastfeeding of preterm infants. However, there are insufficient studies on human milk banks and milk donation in China. Objectives(1) To investigate postpartum women's knowledge, attitude and practice regarding human milk banks and milk donation and to analyze the influencing factors. (2) To explore reasons why postpartum women reject milk donation and donor milk. Design and settingsA cross-sectional survey was conducted from February 2019 to July 2019 at two hospitals in Wuhan, a large city in central China. ParticipantsMothers who returned to hospital for postpartum follow-up within six months participated in this survey (N = 1078). MethodsQuestionnaires were used to obtain sociodemographic data and to determine participants’ knowledge, attitude and practice regarding human milk banks and milk donation. FindingsOf the respondents, 216 (20%) had prior knowledge of human milk banks and milk donation. For the sub-domain of knowledge, the item with the highest correct response rate was the benefit of breast milk, and the item with the lowest correct rate was the acceptance of donor human milk. For the sub-domain of attitude, 811(75.3%) of participants held a supportive attitude for the establishment of human milk banks, and 877(81.3%) were supportive of donating breast milk while 412 (38.3%) were supportive of accepting donor human milk. For the sub-domain of practice, the practice of milk donation was not optimistic as participants lacked interest in donating breast milk and spreading knowledge of breast milk banks, and only 28.3% of participants indicated that they would donate breast milk continuously. Participants’ age, educational background, weight of the newborn and having prior knowledge of human milk banks were factors that could positively predict their knowledge, attitude and practice associated with human milk banks and milk donation; medication usage during pregnancy or lactation was a factor negatively predicting their knowledge about human milk banks and milk donation. ConclusionThis study reveals that a majority of postpartum women are supportive of human milk banks and more willing to donate breast milk than receive donor milk. Lack of knowledge about human milk banks and safety concerns are the main factors hindering postpartum women from donating or accepting donor milk. Findings suggest that it is important to enhance public awareness regarding human milk banks as potential resources for life-saving therapy for preterm infants.This information should be disseminated during the early stage of the establishment of human milk banks. Moreover, health education of pregnant women should include the importance of human milk as well as the alternative and safety of donor milk from milk banks, especially for promoting the health of preterm infants and infants who are unable to receive mothers’ breastmilk.
