Acceptability to donate human milk among postnatal mothers at St. Francis hospital Nsambya, Uganda: a mixed method study

Background The World Health Organization recommends the use of donated human milk (HM) as the second-best option for mothers who are temporarily unable to provide sufficient breast milk to meet the needs of their infants. However, HM donation is yet to become an accepted practice in Uganda. We assessed the level of, and factors associated with acceptability to donate HM among postnatal mothers at St. Francis Hospital Nsambya (SFHN). Methods A cross-sectional sequential explanatory mixed method study was conducted between October 2018 and March 2019. A questionnaire on sociodemography, awareness and likely acceptability to donate HM was administered to 410 postnatal mothers at SFHN. Multivariate logistic regression analysis was undertaken to determine factors associated with acceptance of HM donation. Focus Group Discussions (4) and Key Informants Interviews (4) were used to explore factors influencing behaviours to donate human milk. Qualitative data were analysed using a content thematic approach. Results Overall acceptance of donating the HM was 77.6%, and the significant factors were: willingness to express the HM (AOR 7.5; 95% CI 3.01, 18.68); wet-nursing knowledge (AOR 2.3; 95% CI 1.1, 5.0) and visit to under-5 years’ clinic (AOR 21.3; 95% CI 2.3, 196.9). The major themes in relation to accepting to donate HM were wet nursing experience, and confidence in donating the HM, and its perceived effectiveness. There were concerns about the safety and adequacy of HM and fear of transmitting criminal behaviours and mental illness through human milk. Conclusions Acceptance to donate HM among postnatal mothers at St. Francis Hospital Nsambya was very high. Willingness to express and store human milk, prior knowledge about wet nursing and a visit to an under-five outpatient clinic were associated with acceptance. Thus, establishing a human milk bank is feasible in the study setting.
