Background:There are well-documented disparities in rates of continued breastfeeding. Existing research regarding breastfeeding during COVID-19 has raised concerns that the pandemic may have exacerbated these disparities.Research Aims:The aim of this research was first to quantify disparities in any breastfeeding associated with the maternal factors of race/ethnicity, age, insurance payor, and zip code rates of education in North Carolina. Second, we aimed to investigate any changes in these disparities before and during the COVID-19 pandemic.Method:This was an observational study, with a retrospective, longitudinal design. Participants included infants who were born in one of eight medical centers across North Carolina from either September 1, 2019 to October 31, 2019 (pre-COVID: n = 1,104) or from April 1, 2020 to May 31, 2020, (during COVID: n = 1,157), and whose caregivers reported whether they were breastfeeding at either a 3-month or 6-month postnatal follow-up (N = 2,261). Mixed effects logistic models, including random effects of zip code, assessed predictors associated with probability of breastfeeding cessation at 3- and 6-month child well-check.Results:Overall, younger maternal age, being non-Hispanic Black, not having commercial insurance, and residing in a zip code with lower rates of higher education, were all independently associated with earlier breastfeeding cessation across both cohorts. Disparities did not significantly change during the COVID-19 pandemic.Conclusion:We did not find support for the hypothesis that the COVID-19 pandemic might have exacerbated breastfeeding disparities. Nevertheless, there is a continued need to eliminate existing disparities.

Background:Breastfeeding has been the subject of scientific studies for many years. Identifying the current trends and hotspots in breastfeeding research can further advance understanding in the field.Research Aim:This study aimed to review the basic and conceptual structure of the literature on breastfeeding from a macro perspective.Methods:The dataset for this study included 8,509 articles published between 1980 and 2022 accessed through the Web of Science database. Bibliometric methods were used to assess the growth direction of the literature on breastfeeding, the publication performance by country, influential journals and articles, co-citation networks, and keywords.Results:Research on breastfeeding developed slowly until the 2000s, at which point the speed of growth increased. The United States was the country in which most of the breastfeeding research was produced as well as being at the center of international collaborative networks. An examination of author productivity established that there was no specialization in breastfeeding. The results of citation and keyword analyses demonstrated that the literature on breastfeeding is sensitive to current developments, and the psychological aspects of breastfeeding have been intensively discussed, especially in recent years. Moreover, our results demonstrate that breastfeeding support programs are a distinct area if interest. Despite the abundance of research available, more studies are needed for specialization in this field.Conclusion:This broad overview of the field of breastfeeding research can inform the direction and advancement of the literature.

Background:Women with a cancer history report high distress during pregnancy and infant feeding. Despite the clear advantages of breastfeeding, little is known about factors influencing infant feeding behavior in women with cancer history.Research Aim:This three-time point longitudinal study aimed to explore the centrality of pregnancy and infant feeding experiences in 17 pregnant women with a cancer history (cases) compared to 17 pregnant women without cancer history (controls).Methods:During pregnancy, participants filled out the Centrality of Events Scale and an ad hoc questionnaire about specific emotions, concerns, and expectations about infant feeding (T1), and their childbirth and infant feeding experiences during hospitalization (T2), and at 3-months postpartum (T3).Results:Results at T1 demonstrated that participants with a history of cancer reported a higher perception of negative judgment and moral choice about breastfeeding than participants without a history of cancer. At T2 they reported a more positive childbirth experience than controls. From T2 to T3 participants with a history of cancer breastfed at a higher percentage than controls, and at T3 they reported higher levels of emotional and physical pleasure about the infant feeding experiences.Conclusions:Women with cancer history may experience a higher emotional and physical pleasure with infant feeding. Despite initial difficulties, a greater prevalence of breastfeeding was present for women with a history of cancer. Although this is a small sample, this research suggests that support and promotion of breastfeeding might be very effective after a serious medical diagnosis.

Background:Recent calls-to-action have recommended the use of gender-inclusive language in the field of human lactation research and clinical care. However, little empirical evidence about parental acceptance and understanding of this new terminology exists.Research Aim:To assess understanding and acceptance of an inclusive language revision of the Breastfeeding Attrition Prediction Tool (BAPT).Methods:This was a prospective qualitative study consisting of two phases, a survey followed by cognitive interview. Pregnant people (N = 16) were recruited from the Vermont Special Supplemental Nutrition Program for Women, Infants, and Children, which uses the BAPT as a standard of care. The study team revised the BAPT (e.g., changed terms like “breast milk” to “human milk”). Study participants completed the Revised BAPT and then participated in a cognitive interview by phone to assess their understanding and acceptance of revised, inclusive language.Results:Most inclusive language was well understood and accepted by participants. Proposed revisions to the survey to replace terms like “breastfeeding” with other terms like “chestfeeding” or “bodyfeeding” were more difficult for participants to understand and were not well accepted.Conclusions:While it is clear that language in human lactation research and clinical practice should be revised to be more gender inclusive, specific inclusive terms elicit different levels of understanding and acceptance. Inclusive language options should be tested with target populations and more research is needed in this area.

Background:Research gaps exist with regard to paternal attitudes towards breastfeeding and the association between fathers’ attitudes and the type of breastfeeding.Research Aims: (1)To analyze the psychometric properties of the Spanish version of the Iowa Infant Feeding Attitude Scale in fathers, and (2) to examine the association between fathers’ attitudes and type of breastfeeding.Method:We used a cross-sectional study design to analyze the scale’s psychometric properties and performance.Results:A total of 639 fathers participated in the study. The mean age was 35.83 years (SD = 4.65) and 67.3% (n = 430) were married or in a civil partnership. We observed an adequate fit in the confirmatory factor analysis: TLI = 0.96, CFI = 0.97 and RMSEA = 0.05. The overall internal consistency was 0.76. Between 1–6 months, 48% (n = 307) of participants’ babies were exclusively breastfed, 35.2% (n = 225) were partially breastfed, and 16.7% (n = 107) were exclusively formula fed. Statistically significant differences were shown in attitudes towards breastfeeding, depending on the type of breastfeeding, between 1 and 6 months (F = 54.67; p < .001). Fathers who reported that their baby had been exclusively breastfed scored higher on attitudes towards breastfeeding. Statistically significant differences were also found between partial breastfeeding and formula feeding.Conclusions:The Spanish version of the Iowa Infant Feeding Attitude Scale is a valid and reliable instrument for measuring paternal attitudes towards breastfeeding.

Background:Breastfeeding continuation rates are low in Ireland. The Breastfeeding Observation and Assessment Tool (BOAT) was developed to assist public health nurses in assessing breastfeeding challenges; however, little is known of its actual usage, the level of training experienced or desired by public health nurses, or their level of confidence in the support they provide to breastfeeding mothers.Research Aim:To identify the current practices and support needs of public health nurses who provide breastfeeding support in Ireland.Method:An online questionnaire was devised to collect respondents’ confidence with breastfeeding issues, caseload, and practices. It was distributed to public health nurses with a current child health caseload in one Community Healthcare Organization. Mann Whitney U tests were used to ascertain the relationship between public health nurses’ confidence level and those with qualifications in midwifery or as an International Board Certified Lactation Consultant (IBCLC).Results:The survey was completed by 66 public health nurses. Only 14 respondents (21.2%) indicated that they always used the BOAT. The most common reason for not doing so was a lack of education on its use (n = 17, 25.8%). Postholders also certified as IBCLCs were considered by participants to be the most appropriate professionals to resolve certain breastfeeding issues. Confidence levels to manage breastfeeding issues were highest among public health nurses with IBCLC credentialing (U = 12.5, p = .001) while no difference was seen when comparing those with a midwifery degree to those without (U = 184.0, p = .92). Face-to-face workshops and blended-learning approaches were ranked as the preferred formats for breastfeeding education (Median rank = 2).Conclusions:Breastfeeding education incorporating a face-to-face component is needed to support public health nurses who work with breastfeeding mothers, as is prioritization of recruitment in the community of public health nurses with IBCLC credentials.

One of the factors contributing to the disparities still present by race in the United States may be inequitable access to lactation education. In order to ensure that all parents receive the education they deserve to make informed infant feeding decisions, two checklists were created for patient and healthcare professional use, respectively. This paper describes the process of creating and validating the healthcare professional and patient checklists. The authors completed a review of the most recent literature surrounding barriers to lactation initiation and retention in the Black community to create the initial version of the checklists. Expert consultation was then utilized to assess their content validity. Local healthcare providers unanimously agreed that pregnant and postpartum parents need more education and support than currently provided. The consulted experts described the two checklists as useful and comprehensive and offered feedback for their revision and optimization. Implementing these checklists offer the possibility of increasing provider accountability in delivering adequate lactation education and enhancing client lactation knowledge and self-efficacy. Further research is needed to assess the effect of implementation of the checklists in a healthcare setting.

Background:Labels are a key element of the marketing strategies of infant formula companies, and often include text or images that idealize their use, undermining efforts to promote breastfeeding.Research Aims:To evaluate the prevalence of marketing cues that idealize infant formula on labels of products commercialized in Uruguay and to assess changes after a periodic monitoring of compliance with the International Code of Marketing of Breast-Milk Substitutes (IC).Method:This study is a descriptive, observational, and longitudinal assessment of the information included on infant formula labels. The first data collection was in 2019, as part of a periodic assessment to monitor the marketing of human-milk substitutes. In 2021, the same products were purchased to evaluate changes in their labels. Thirty-eight products were identified in 2019, of which 33 were still available in 2021. All information available on the labels was analyzed through content analysis.Results:Most products included at least one textual or visual marketing cue idealizing infant formula in both 2019 (n = 30, 91%) and 2021 (n = 29, 88%). This represents a violation of both the IC and national regulations. References to nutritional composition were the most frequent marketing cue, followed by references to child growth and development. No relevant changes were observed after the periodic assessment conducted by the Uruguayan government.Conclusions:Monitoring compliance with the IC per se cannot be expected to trigger changes in the marketing strategies of infant formula companies. More explicit regulations and strong enforcement mechanisms are needed to end the inappropriate marketing practices on infant formula labels.

IntroductionInduction of lactation in a non-gestational parent has numerous potential benefits including parent–child bonding, optimal nutrition, and health benefits to the child and breast- or chest-feeding parent. For transgender women and nonbinary people on estrogen-based, gender-affirming hormone therapy, the ability to nourish their infants through production of their own milk may also be a profoundly gender-affirming experience. Two prior case studies have been published describing induced lactation in transgender women, but analysis of the nutritional quality of the milk produced has not been previously described.Main issueHere we describe the experience of a transgender woman who underwent successful induction of lactation in order to breastfeed her infant, who was gestated by her partner.ManagementThrough modification of exogenous hormone therapy, use of domperidone as a galactogogue, breast pumping, and ultimately direct breastfeeding, the participant was able to co-feed her infant for the first 4 months of life. We provide a detailed description and timeline of the medications used, laboratory and electrocardiographic measurements, results of the participant’s milk analysis showing robust macronutrient content, and description of the participant’s experience in her own words.ConclusionThese findings provide reassurance about the adequacy of nutrition from human milk produced by non-gestational transgender female and nonbinary parents on estrogen-based, gender-affirming hormone therapy, and support the importance of this experience on a personal level.

Background:Tandem breastfeeding is defined as a situation in which a mother continues breastfeeding her child through a subsequent pregnancy, including after the new baby is born. In some countries where motherhood may be delayed and the time between births may be reduced, support for the promotion of tandem breastfeeding is necessary to help mothers continue to breastfeed their eldest child and avoid early weaning. There is no existing research about mothers’ motivations to breastfeed in tandem.Research Aim:To explore the motivations of women to initiate and maintain tandem breastfeeding, based on their lived experience, framed within the self-determination theory.Methods:A prospective, cross-sectional, interpretive, phenomenological study was carried out through in-depth interviews with 15 mothers in Madrid, who had practiced tandem breastfeeding for more than 6 months, and whose weaning of their eldest child had occurred within the previous year. Convenience and snowball sampling were used. The data were analyzed using an established interpretive phenomenological analysis process.Results:Among the motivations for initiating tandem breastfeeding, the following themes were identified: “avoid wasting the effort invested,” “desire such life experience,” and “exercise the freedom to decide.” The motivations for maintaining tandem breastfeeding were classified as “pass on parenting values” and “benefits of teamwork.”Conclusion:The participants based their motivation to tandem breastfeed to follow their freely chosen motherhood model. They discovered the advantages of its implementation, forming a team of themselves and their children, and healing their traumatic perinatal experiences.
