Research about lactation and breastfeeding has exploded since the Journal of Human Lactation (JHL) began publishing in 1985. To discuss the 3-decade-long role of the Journal in promoting, supporting, and disseminating lactation research, editors convened a multidisciplinary group of lactation researchers and providers which comprised three senior researchers and one clinical practitioner, all of whom have a long history of lactation advocacy. Their discussion took place on July 1, 2019. Dr Aimee Eden is a medical anthropologist who leads the qualitative research efforts in a small research department. Her dissertation research focused on the maternal and child healthcare workforce, and the professionalization of breastfeeding support. She served on the Board of Directors of the International Board of Lactation Examiners (2010–2016) and currently serves on the board of the Monetary Investment for Lactation Consultant Certification. Dr Karleen Gribble has been conducting research for 15 years about infant and young child feeding in emergencies, long-term breastfeeding, milk sharing, early childhood trauma, adoption, and fostering. She is an Australian Breastfeeding Association community educator and breastfeeding counselor and a member of the Infant and Young Child Feeding in Emergencies Core Group. Elien Rouw is a practicing physician in Germany specialized in healthy infant care, with a long-standing specialization in breastfeeding medicine. She serves on the Board of Directors of the Academy of Breastfeeding Medicine, is a member of the German National Breastfeeding Committee and their delegate to the World Alliance for Breastfeeding Action. Dr Jackie Wolf is an historian of medicine, whose research focuses on the history of childbirth and breastfeeding practices in the United States and how those practices have shaped women’s and children’s health, as well as public health, over time. Her latest book, published by Johns Hopkins University Press and funded by a 3 year grant from the National Institutes of Health, is Cesarean Section: An American History of Risk, Technology, and Consequence. Dr Sara Gill moderated the discussion. She was a member of the Board of Directors of the International Lactation Consultant Association for 5 years, and has been an Associate Editor of the Journal of Human Lactation for the past 4 years. Her research has focused on breastfeeding among vulnerable populations.

Background:Peer support may help mothers to feel satisfied with their breastfeeding and to continue breastfeeding. However, previous researchers have not examined the influence of peer support on the three breastfeeding-satisfaction domains.Research aim:We aimed to examine the influence of telephone-based peer support on the following three domains of breastfeeding satisfaction among Japanese mothers: maternal satisfaction, perceived benefit to the infant, and lifestyle compatibility with breastfeeding.Methods:Breastfeeding mothers were recruited at four maternity hospitals in Japan to participate in a randomized controlled trial. Data were collected 1 month and 4 months postpartum. Among all of the participants (N = 114), those in the intervention group (n = 60) received telephone-based peer support until 4 months postpartum, and participants in the control group (n = 54) received conventional support. Breastfeeding satisfaction was measured using the short version of the revised Japanese Maternal Breastfeeding Evaluation Scale. Generalized estimating equations and effect size analyses were used to examine the influence of the intervention.Results:On the subscale measuring lifestyle compatibility, participants with peer support had a higher score than those without peer support: regression coefficient 1.54 (95% confidence interval [0.03, 3.04]). The effect size was 0.40 standard deviations among participants with low and mid-level scores at baseline.Conclusion:Although peer support did not change maternal satisfaction or perceived benefit to the infant, it did increase lifestyle compatibility with breastfeeding among these Japanese mothers. This is evidence in favor of increasing the use of peer support.

Background:Although the reasons for discontinued breastfeeding are multifactorial, an unsupportive work environment is consistently reported as a barrier to continued breastfeeding. In the United States, several state breastfeeding advocates have taken a distinctive approach to promote worksite lactation support by developing statewide recognition initiatives aimed at incentivizing employers to support breastfeeding employees by offering public recognition for the worksites’ efforts.Research aim:To identify and describe statewide worksite lactation support recognition initiatives in the United States.Methods:Between May 2016 and June 2017, semi-structured phone interviews were conducted with breastfeeding experts in each U.S. state (N = 60 participants) for this cross-sectional study. Experts in states with a recognition initiative were asked about the background, structure, and requirements of the initiative.Results:Twenty-six states had a current initiative, and some had requirements for providing a private space (n = 19; 73%) and time (n = 18; 69%) for employees to express human milk, as well as a written worksite lactation support policy (n = 10; 38%).Conclusions:This was the first study in which researchers systematically identified ongoing worksite lactation support recognition initiatives in the United States. The results of this work also served to highlight both the similarities and the variety between initiatives. Future researchers should aim to determine the components of an initiative that increase employer support and, in turn, breastfeeding rates.

Background:The World Health Organization (WHO) and the United Kingdom Committee for UNICEF recommend that secondary schools include infant feeding education in the curriculum. However, little attention has been given to the study of educators’ views and practices regarding infant feeding education.Aims:The aims of this research were to (1) explore North Carolina Family and Consumer Sciences teachers’ attitudes towards infant feeding education in secondary schools and (2) describe North Carolina Family and Consumer Sciences teachers’ infant feeding education practices.Methods:Researchers conducted interviews (N = 19) and a survey (N = 137) using a sequential mixed methods design. The constant comparative method was used to analyze interview transcripts. Subsequently, a 33-item survey was developed to assess teachers’ attitudes and practices, and this survey was tested for validity and reliability.Results:The majority of participants supported including infant feeding (n = 119, 86.9%) and breastfeeding (n = 116, 84.7%) education in high school. Approximately half of the participants supported including infant feeding (n = 71, 51.9%) and breastfeeding (n = 64, 46.7%) education in middle school. Participants reported that they taught infant feeding at both levels; topics taught included complementary foods, patterns of infant feeding, and the safe preparation of infant formula. Breastfeeding content was covered primarily in the high school Parenting and Child Development course.Conclusions:North Carolina Family and Consumer Sciences teachers have positive attitudes towards teaching about breastfeeding at the secondary school level. Content about infant nutrition and breastfeeding is currently included in courses that cover child development and human nutrition.

Introduction:Mammary dysbiosis, also known as subacute mastitis, may be associated with nipple blebs. These overlapping diagnoses represent a challenging clinical scenario during lactation. Little research has been published on etiology, management strategies, and outcomes of these concurrent diagnoses.Main issue:We document the treatment and outcome of a patient who presented with left-breast dysbiosis and nipple blebs and whose milk culture grew multi-drug-resistant, methicillin-resistant Staphylococcus aureus. She was treated safely and effectively with intravenous daptomycin and dalbavancin. This has not been described previously in the lactation literature.Management:The 35-year-old lactating gravida 3, para 3 patient presented at 6 months postpartum to a breast surgery clinic with a 1-week history of worsening deep left-breast pain, blebs, and recurrent plugging. She was afebrile and she had no erythema or induration on her breast exam. A culture of her milk grew multi-drug-resistant, methicillin-resistant Staphylococcus aureus, and she was referred to infectious disease for assistance with intravenous antibiotic therapy. She continued to feed expressed milk throughout treatment and demonstrated complete resolution of symptoms 8 weeks later.Conclusions:We report that in patients with a multi-drug-resistant, methicillin-resistant Staphylococcus aureus–positive human milk culture and a clinical presentation of mammary dysbiosis and nipple blebs, intravenous daptomycin and dalbavancin may be an effective treatment.

Background:Induced lactation and relactation are the processes that enable breastfeeding in non-gestating mothers.Research aim:The aim of this study was to describe and interpret the challenges faced by mothers who undergo induced breastfeeding and relactation for adopted infants, infants born via surrogacy, and infants born to same-sex female partners.Methods:A qualitative study was performed using in-depth interviews conducted with Spanish women (N = 9) who had decided to undergo induced lactation or relactation. The data were collected between October 2014 and May 2017. The length of the study was due to the difficulty in locating and recruiting the sample. Interviews were transcribed and coded with the ATLAS.ti v.7.5.7 software. We performed a deductive thematic analysis, creating categories based on the interview questions, which we developed on the basis of previous literature about induced lactation and relactation.Results:Participants described the following challenges: the physical hardships of the process; breastfeeding problems; difficulty with accessing information about induced lactation or relactation; and lack of support from health professionals. Breastfeeding periods lasted from 1.5 months to 4 years. Participants reported that breastfeeding increased the closeness between the mother and child and that this feeling of closeness tended to decrease after breastfeeding cessation.Conclusion:We offer data and analysis that can improve our understanding of the lived experiences of women undergoing the process of relactation or induced lactation and may help guide intervention strategies to support women in this situation.

Background:Debate about mother and infant bed sharing has been polarized between supporters of bed sharing and public health policies that attempt to mitigate the risk of Sudden Infant Death Syndrome. Differences in group demographics may be an important aspect in co-sleeping acceptability.Research aims:The first aim of this study was to investigate infant sleeping location in a dataset of mothers with strong breastfeeding outcomes. The second aim was to investigate the association between infant sleeping location and breastfeeding (exclusive breastfeeding to 6 months and total breastfeeding duration). Finally, we aimed to investigate predictors of breastfeeding duration.Methods:Participants comprised 174 women who had applied to train as counselors with the Australian Breastfeeding Association. Data were compiled from a survey of the participants’ lactation histories, including questions related to the exclusivity and duration of breastfeeding, concerns about and problems encountered during breastfeeding, type of birth, medications during birth, demographics, and infant sleeping location. The study design was a cross-sectional, one-group survey design.Results:A high proportion of participants in this study bed shared and room shared: At 0–1 month (n = 58), 33% of participants bed-shared, which increased to 58% by 6–12 months (n = 80). Infants who co-slept were more likely to be exclusively breastfed at 6 months (χ2 (2, n = 116) = 4.83, p = .03) and had longer breastfeeding duration (t (62.61) = 3.81, p < .001).Conclusions:Breastfeeding targets have been difficult to achieve globally, and innovative ideas are required to improve breastfeeding outcomes through public health messaging. There was a strong association in the current study between breastfeeding outcomes and degree of closeness of the infant to the mother at night. This finding should be brought into the discourse on breastfeeding and infant sleep arrangements, accompanied by evidence-based advice about safe sleeping and the promotion of breastfeeding.

Background:In 2015, the median duration of exclusive breastfeeding was 2.2 months in Armenia, and only 15% of 4–5-month-old children were exclusively breastfed, indicating an issue with breastfeeding knowledge and practices.Research aim:To identify the main barriers to optimal breastfeeding practices in Armenia.Methods:We used qualitative research methods via focus group discussions and in-depth interviews with four groups of providers from different levels of care, and mothers of young children, from Yerevan city and two provinces, Lori and Shirak. Overall, eight in-depth interviews and 13 focus group discussions were conducted with a total of 99 participants. Qualitative content analysis was applied, with elements of both inductive and deductive approaches.Results:We identified two main categories of barriers to optimal breastfeeding—systemic barriers and knowledge deficiencies. The main themes within systemic barriers were lack of skilled breastfeeding support services and low motivation of providers—mainly related to inadequate recognition of their role in breastfeeding counseling and low remuneration. The main knowledge-related barriers were insufficient counseling of mothers, lack of reliable information sources about infant feeding, and misconceptions among both mothers and providers.Conclusion:Optimal breastfeeding is crucial for the best start to an infant’s life; however, there were a number of barriers to optimal breastfeeding practices in Armenia. Our findings and recommendations could help policymakers apply effective strategies for improving breastfeeding rates in Armenia. Considering the similar historical backgrounds of the post-Soviet countries, our findings could also be applicable to other Commonwealth of Independent States countries.
