Human Milk Sharing in the United States: A Scoping Review

Factors associated with informal human milk sharing among donors and recipients: A mixed-methods systematic review

BACKGROUND

The multiple benefits associated with the provision of human milk exceed individual health outcomes, engendering substantial economic, societal and environmental domains. Human milk is the absolute, unparalleled source of nutrition for infants. Informal human milk sharing is a modernistic and rapidly progressing practice. No systematic review of the factors associated with this contemporary practice among donors and recipients of informal human milk sharing exists.

AIM

The aim of this review was to identify, evaluate, synthesize and integrate the evidence on the factors associated with informal human milk sharing among donors and recipients.

METHODS

A mixed methods systematic review was conducted according to the Joanna Briggs Institute methodological guidance utilizing a convergent integrated approach. The following databases were systematically searched: CINAHL, Scopus, Medline and Embase and Web of Science between inception to August 2023. A grey literature search was conducted using multiple techniques. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

RESULTS

Twenty-four studies were included in this review. Ten integrated findings relating to the factors associated with informal human milk sharing among donors and recipients were identified. The four integrated findings pertaining to donors included: altruistic motivation and value, resistance to commercialization and overcoming inaccessibility, uniting digital and personal connectedness and lack of awareness and acceptance of informal human milk sharing in healthcare settings. The six integrated findings relating to recipients included: maternal or infant factors, superiority and advantageous impact of breastmilk, human milk bank influences, digital connections and transparency, healthcare professional facilitation of informal human milk sharing, and professional and logistical implications.

CONCLUSION

This review highlighted a multitude of factors that motivate, facilitate and impede the practice of informal human milk sharing. Future research is required to explore these factors further within broader geographical locations to enhance the generalizability and rigor of the body of knowledge. Further studies should consider the exploration of the experiences and psychological impact of informal human milk sharing on donors and recipients. The provision of human milk to all infants is an imperative public health endeavor and thus positioning this as a key benchmark for research and practice is crucial.

Beliefs and views of breastfeeding mothers regarding human milk banking: A qualitative study

OBJECTIVE

The aim of the study was to determine the beliefs and opinions of breastfeeding mothers about human milk banking.

METHODS

This study was conducted as a case study, which is a qualitative research method. The population researched consisted of women who applied to the Gaziantep Health Care Family Health Center between June and December 2022. The sample included 30 mothers selected through purposive sampling. The data were collected using a descriptive characteristics form and a semistructured interview form. Ethical committee and institutional approvals were obtained. The data were analyzed using the MAXQDA qualitative research software program.

RESULTS

The majority of the breastfeeding mothers had limited knowledge about human milk banking and considered it religiously problematic. They held the belief that breastfeeding siblings should not marry each other on religious grounds. The mothers were willing to act as wet nurses in case of necessity, but they expressed a preference against having their own baby nursed by another woman. They also stated that they would consider using milk banks only if the information provided was limited to the mother and baby. Additionally, it was observed that if they found themselves in a difficult situation, they would only seek a wet nurse from their immediate social circle.

CONCLUSION

The breastfeeding mothers expressed that milk banking was a beneficial practice; however, they had religious reservations about it. It was observed that they would be willing to donate their milk to these banks and use them in times of need under certain conditions. These conditions included ensuring that the milk is not mixed, providing information about the mother and baby to families, having babies of the same sex, and adhering to strict cleanliness and hygiene measures.

The Climate Crisis and Breastfeeding: Opportunities for Resilience

The climate crisis is an emerging global challenge that poses potential risks to breastfeeding practices and outcomes. There are multifaceted effects of climate change affecting the breastfeeding dyad across environmental, societal, and human health dimensions. Breastfeeding support in the face of climate change will require solutions at the structural level-healthcare, community, and workplace settings-and at the mother-infant dyad level. Breastfeeding can additionally be an adaptive response to crisis situations and can mitigate some of the environmental challenges associated with climate change. Despite the undeniable significance of climate change on breastfeeding (and vice versa), our perspective as experts in the field is that this topic has not been systematically addressed. Although we highlight some of the challenges, potential solutions, and co-benefits of breastfeeding in the context of climate change, there are numerous issues that could be further explored and necessitate additional preparedness planning.

Perspectives and factors associated with informal human milk sharing: a mixed-methods systematic review protocol

Background

The practice of informal human milk sharing is a relatively new phenomenon and poses significant questions in the domain of infant feeding. Informal human milk sharing is a means of donating human milk from another lactating individual who is not the child's biological parent, in a casual manner, that is, without the involvement of health professionals or agencies. The advent of digital technology has facilitated the donation and receipt of human milk through digital online platforms and thus has amplified this modern practice. This research aims to comprehensively examine and synthesize evidence about the motivations, barriers, facilitators and experiences of individuals who both donate (donors) and the primary care givers of the infants who receive (recipients) human milk informally to provide to infants.

Methods

A mixed-methods systematic review will be undertaken. This review will consider qualitative, quantitative and primary mixed-methods studies which report on the factors associated with informal milk sharing, and on donors' and recipients' experiences of the practice. Primary mixed-method studies will be included if the individual qualitative and quantitative components can be extracted. Five databases will be searched for studies on informal human milk sharing published from inception of the database. Study quality will be evaluated using the standardized JBI critical appraisal tools, selected based on the methodology in each individual study. Data extraction will be conducted using the JBI mixed methods data extraction form followed by data transformation, synthesis and integration. This mixed-methods systematic review will follow a convergent integrated approach in accordance with JBI guidance.

Discussion

Informal human milk sharing is a novel practice in the domain of infant feeding. This review will enable a thorough understanding of this practice from both the donors and recipients' perspective and will have implications for healthcare professionals, policy and future clinical decision-making.
