Background:Pumping is a common practice in the United States, but it can be uncomfortable and lead to concerns about milk supply. The fit of the flange, or breast shield, used while pumping can contribute to or alleviate these problems. Flanges are available in a wide variety of sizes, and there are inconsistencies in guidance provided by healthcare providers and pump manufacturers for parents choosing a size. There have been no studies comparing different methods of sizing in terms of comfort and milk output.Research Aims:The aim of this research was to examine differences in milk output and comfort using two methods of flange sizing.Method:A within-subject cross-over design with a convenience sample of parents exclusively feeding their own human milk was used to compare comfort and milk yield between using smaller-fit and standard-fit flanges. Participants pumped for 1 week with each set of flanges and recorded milk output and comfort outcome measures. Data were collected on participant demographics, nipple measurements, and flange sizes used.Results:When compared to the newer small-size fitting, participants using the standard fit flanges had significantly less milk output (mean difference = −15.0 g, 95% CI [−25.0, −5.0], d = −0.51, p = 0.004) and less comfort (mean difference = −1.2, 95% CI [−1.6, −0.91], d = −1.23, p < 0.001).Conclusion:Flange fitting is a process that should be individualized to the patient and may require a trial of one or more sizes during a pumping session. Smaller sizes determined using this individualized process and starting with nipple tip measurement may be used without compromising milk output or comfort.

Background:Medical students should have adequate knowledge and positive attitudes toward breastfeeding to support breastfeeding dyads. No studies in Croatia have explored breastfeeding knowledge, attitudes or intentions among medical students.Research Aim:To investigate breastfeeding knowledge, attitudes and intentions among medical students at the University of Split School of Medicine.Methods:A cross-sectional study was conducted from March to April 2023, using online and written questionnaires. All medical students without children were eligible to participate. The validated Breastfeeding Intentions, Attitudes, and Knowledge Questionnaire (BIAKQ) was used. Sociodemographic data were collected. Analysis was conducted using descriptive statistics, t tests, and Mann-Whitney U test.Results:A total of 357 medical students participated (response rate 64.1%). There was no significant difference between preclinical and clinical students. Students who attended the elective “Breastfeeding Medicine” demonstrated significantly more positive attitudes toward breastfeeding (Mean Rank = 215.62) than those who did not attend (Mean Rank = 173.58; U= 5468.50, p = 0.010); however, no significant difference was found in knowledge or intentions. Female students had significantly more positive attitudes compared to male students (Mean Rank = 189.47 vs. Mean Rank = 150.55, U = 9796.50, p = 0.001), whereas male students expressed significantly more positive intentions (M = 36.97, SD = 5.26 vs. M = 34.44, SD = 5.86, t = −3.69, p = 0.002). The mean knowledge score was 11.92 (SD = 1.43) out of 13 points. Negative attitudes towards breastfeeding beyond 1 year and breastfeeding in public were found.Conclusion:Despite adequate breastfeeding knowledge, some medical students demonstrated negative attitudes and intentions toward breastfeeding. Including breastfeeding education into core medical subjects focusing on the importance of breastfeeding for maternal and infant health and the risks of formula feeding could help improve attitudes, especially during the clinical years. It would also be important to address prevailing prejudices.

The importance of a child receiving their mother’s own milk (MOM) in the care and treatment of preterm infants is undisputed in the literature. Despite this, lactation support in the Neonatal Intensive Care Unit is often fragmented. Gaps in adequate lactation care for infants receiving MOM, and barriers to that lactation care, can contribute to healthcare disparities and outcome inequalities. Here, I outline a comprehensive lactation care manager model based on the concepts of continuity of care and care management. This is a starting point for discussion that may be helpful in informing future research and adequate lactation care options.

Background:Globally, rising trends in gestational diabetes and body mass index contribute to maternal and neonatal morbidity and mortality. Lifestyle modifications and breastfeeding may reverse this effect, although few studies combine these into one intervention.Research Aims:To measure postpartum weight retention, breastfeeding duration, hemoglobin A1C, and mean arterial blood pressure at 6 months postpartum among women with elevated pre-pregnancy body mass index.Methods:The electronic Monitoring of Mom’s Schedule study (eMOMS™) was a feasibility, three-arm, randomized controlled trial modeled after a Diabetes Prevention Program and breastfeeding support. A health coach delivered a 12-month virtual intervention. Study arm results were compared using Wilcoxon signed-ranks exact test reporting from a two-sided test and bootstrapped samples with 95% confidence intervals.Results:Between September 2019 and May 2021, 100 individuals were screened, and 35 were randomized: nine to Group 1, 14 to Group 2, and 12 to Group 3. At baseline, participants averaged 13.0 (SD = 2.5) weeks gestation, with a mean pre-pregnancy body mass index of 29.7 (SD = 3.0). With 5,000 bootstrapped samples, mean weight retention from baseline to 6 months postpartum was: 4.0 kg, 95% CI [1.6, 6.2] for Group 1; 3.7 kg, CI [-1.8, 9.8] for Group 2; and 7.5 kg, CI [4.1, 11.6] for Group 3. Mean (exclusive) breastfeeding duration was 9.3 weeks, 95% CI [0.43, 26.1]; 9.6 weeks, CI [4.4, 15.7]; and 15.1 weeks, CI [6.5, 23.3] for each group, respectively.Conclusion:Our intervention was positively associated with postpartum weight retention and breastfeeding duration. Future research is needed to assess intervention components.

Background:Web-based prenatal education is increasingly employed, but its association with increased breastfeeding and predictors of breastfeeding success is uncertain.Research Aims:Our primary aim was to evaluate our live, online intervention’s association with exclusive breastfeeding at hospital discharge. Secondarily, we aimed to describe participants’ reports of the intervention on predictors of breastfeeding success.Method:We used a retrospective quasi-experimental cohort design to assess the association between our intervention and exclusive breastfeeding at discharge. The intervention consisted of an evidence-based live, online, 2-hour class open to all prenatal patients and supporters at our urban community medical center from June 2020 through April 2022. Patient characteristics and breastfeeding rates were extracted from the electronic medical record. Samples were drawn using stratified random sampling. Three logistic regression models were conducted to assess the associations between the intervention and exclusive breastfeeding. Two surveys assessed the participant reports of the intervention.Results:Samples of the first model, comprised of 160 participants and 160 non-participants, were similar in important characteristics. Participants were 2.12 times (95% CI [1.12, 3.69]) more likely to exclusively breastfeed. Participants reported positively on the impacts of the intervention on breastfeeding predictors.Conclusions:Our live, online intervention was significantly associated with an increased likelihood of exclusive breastfeeding at hospital discharge. A randomized, prospective examination of the intervention’s association with breastfeeding duration would further define its impact.

Anwar Fazal has been a driving force in the founding of several civil society organizations in the areas of health, human rights, environment, and peace, that have been at the forefront of activism locally, nationally, and globally. In this interview, he shares his journey of 6 decades, involving a multiverse of public interest issues, which led him into the breastfeeding movement. It began with the setting up of the International Baby Food Action Network (IBFAN), a pioneering action that triggered the formation of Health Action International (HAI), Pesticide Action Network (PAN), and the World Alliance for Breastfeeding Action (WABA). Each of these resulted in several unique frameworks and codes relating to the marketing of infant foods, pharmaceuticals, and pesticides. They also led to the formation of World Breastfeeding Week, now being celebrated globally. Anwar studied Economics at the University of Malaya and did his postgraduate studies in Education. Anwar has served as a visiting professor at the University of Science Malaysia and the International Islamic University Malaysia (IIUM). He is the recipient of the Right Livelihood Award, popularly known as the “Alternative Nobel Prize,” for his work on breastfeeding and infant nutrition and other health, environmental, and consumer issues. La Leche League International (LLLI) and the United Nations Development Programme (UNDP) have honored him with the International Health Award and the Millennium Development Goals Award. He has written extensively on breastfeeding. He is currently Chairperson Emeritus of the World Alliance for Breastfeeding Action (WABA) and continues to speak out actively on protecting, promoting, and supporting breastfeeding.

Introduction:Favipiravir is a known anti-influenza agent that has been used globally, especially during the coronavirus disease 2019 (COVID-19) pandemic. This drug has been important for treating influenza and other emerging infectious diseases, although it was ultimately proven to be ineffective for COVID-19. Currently, no studies have reported the human-milk transfer of favipiravir at doses of 1,600–3,600 mg/day in the treatment of diseases, including COVID-19.Main Issue:A 38-year-old mother gave birth at 38 gestational weeks because of severe respiratory distress caused by COVID-19. Considering her illness and the inadequate information available on the safety of favipiravir in breastfeeding, she chose formula feeding for her infant. However, she still provided human milk and blood samples for the analysis of drug concentrations.Management:Five concentrations of favipiravir in the mother’s milk and four in maternal blood were measured (3.0–80.9 and 3.5–78.4 μg/ml, respectively). Metabolites of favipiravir were not measured. The relative infant dose was 15.2%. The favipiravir concentration in human milk was as high as 80.9 μg/ml at 1.3 hours after the medication was given, when maternal blood levels are considered to be at their highest; however, favipiravir concentration was low in human milk immediately before medication administration (5.9–9.7 μg/ml).Conclusion:Breastfeeding is not contraindicated in mothers undergoing favipiravir therapy and would be safer immediately before medication. Avoiding feeding at the peak time (1.3 hours after medication) minimizes infant exposure.

Background:Psychosocial predictors of breastfeeding and changes in those factors during pregnancy, along with the relationship of those changes with both breastfeeding and smoke use and exposure, are not well explored.Research Aim:The aim of this study was to identify distinct trajectories of psychosocial determinants of breastfeeding and smoking in pregnant women.Methods:We used a longitudinal study design and data from a randomized controlled trial conducted among smoke-exposed pregnant women and their infants. Participants were recruited early in pregnancy and were surveyed at ≤ 16 and 32 weeks gestation, delivery, 3 and 6 months postpartum for breastfeeding intentions, initiation, continuation, and smoke use and exposure. Psychosocial variables associated with breastfeeding were measured at baseline and 32 weeks gestation using the Mitra index, a structured questionnaire that assesses barriers and facilitators of breastfeeding intentions. Latent class growth analysis was performed using Mitra scores to identify distinct subgroups of participants with different trajectories. Sociodemographic characteristics, breastfeeding, and tobacco smoke use and exposure were compared across classes.Results:Three or four trajectories were identified for each of the six Mitra scores. Trajectories for all Mitra scores were associated with breastfeeding intention and initiation. Overall, Mitra, knowledge, self-efficacy, social support, and time barrier classes all differed by tobacco smoke use or exposure.Conclusion:Trajectories of breastfeeding knowledge, self-efficacy, social support, and time to breastfeed/social barriers are associated with tobacco smoke use and exposure during pregnancy. Encouragement to breastfeed and to cease and avoid tobacco smoke should start early in pregnancy, focusing on these determinants to improve health outcomes.

Breastfeeding offers significant health benefits for both mothers and infants, particularly preterm infants, where it serves as a therapeutic strategy to reduce mortality and morbidities. However, breastfeeding practices are threatened globally by societal norms and systemic barriers at both micro and macro levels. This paper explores the complex interplay of these barriers and facilitators, focusing on the Neonatal Intensive Care Unit (NICU) setting. Preterm infants face specific feeding challenges due to immature physiological functions, yet evidence supports that strategies like cue-based feeding and individualized care can enhance feeding success and health outcomes. For mothers, initiating and maintaining lactation after preterm birth is critical but challenging, with early lactation support and achieving sufficient milk volume being key predictors of success. Partner support significantly influences lactation outcomes, although more inclusive research is needed for diverse family structures. In the NICU, a multidisciplinary approach to lactation care is vital, emphasizing the need for experienced staff and family-centered practices. NICU design, policies promoting parental presence, and adherence to Baby-friendly Hospital Initiative guidelines further support breastfeeding. This paper aims to provide directives for local breastfeeding policies through an integrated approach, considering societal attitudes and healthcare practices. The findings advocate for improved lactation support in NICUs, inclusive language and policies, and further research into diverse familial and gender roles in breastfeeding.

Establishing lactation when mother and infant are separated, such as when the neonate is admitted to the neonatal intensive care unit (NICU), is challenging. The most common clinical advice is to express milk eight or more times per day, every 3 hours, around the clock. Sometimes, the first time that parents hear this is after the birth of their baby. This can be overwhelming and sometimes unachievable. A five-step paradigm shift is proposed that refocuses lactation care on providing evidence-based assistance and ongoing clinical education, and assessment beginning prenatally and extending past maternal discharge, to improve outcomes through curated support. Simple guidelines can begin with expressing milk at least five times a day by Day 5 of life (5 × 5), and expressing milk at least once between 0100 and 0500 (overnight pumping). With these measures, neonatal care in the NICU setting can provide personalized and achievable guidance on pumping schedules.

Background:Pasteurized donor human milk provides a safe and desirable alternative when a parent’s own milk is insufficient or unavailable. Currently, the demand for donor human milk exceeds the available supply. Little is known about the beliefs breastfeeding individuals have about milk bank donation.Research Aims:The aims of this exploratory study were to (a) provide a preliminary estimate of how well intention can be predicted, and to suggest which of the global constructs of the Reasoned Action Approach has the most influence on intention; and (b) identify the salient, top-of-the-mind beliefs underlying the intention to donate some of the milk an individual is currently producing to a milk bank.Methods:An exploratory, cross-sectional study design, based on the Reasoned Action Approach, was used to measure the theory’s global constructs and elicit beliefs underlying the intention to donate milk of lactating individuals (N = 118) living in Indiana, Illinois, Missouri, and Kentucky. Thematic and frequency analyses and multiple regression were performed.Results:Quantitative analyses found that injunctive norm and the autonomy component of perceived behavioral control were independently associated with intention. Qualitative analyses identified the advantages (e.g., help and save babies, won’t waste milk), referents who support (e.g., husband, family), and facilitators (e.g., having a convenient, close location, having more knowledge and information) of donating milk.Conclusions:This research provides insight into how milk banks might recruit and retain donors. Additional quantitative research with a larger sample is necessary to confirm the preliminary findings of this study.

Background:The number of validated questionnaires that assess the level of breastfeeding competence of primary care professionals who attend lactating mothers is limited.Research Aim:To validate the CAPA (Competència en l’Atenció Primària sobre Alletament [Breastfeeding Competence in Primary Care]) questionnaire into Spanish in collaboration with professionals from the primary care services of the Comunidad de Madrid (Spain).Methods:In this multicentric study, four bilingual healthcare professionals translated the CAPA questionnaire into Spanish and back-translated it into Catalan. The cross-cultural adaptation included a discussion by an expert committee, a review by a philologist, and a pilot study that involved 13 healthcare residents. We randomly selected professionals from specialties involved in breastfeeding. The re-test was conducted 3 weeks later, aiming to avoid changes in the studied population. We performed a factor analysis to identify underlying constructs and hypothesis-testing to assess the validity of the questionnaire and estimated the Cronbach Alpha and intraclass correlation coefficient (ICC) to assess its reliability.Results:A total of 198 professionals participated by responding to the questionnaire. Factorial analysis showed that the questionnaire was unidimensional. Hypothesis testing showed that, of all the considered professional groups, midwives achieved the highest mean score (M = 131.7, SD = 10.9, p < 0.001). Amongst the other professionals, only 26.5% achieved a basic level of breastfeeding competence. The Cronbach alpha and ICC were 0.852 (95% CI [0.821, 0.880]) and 0.890 (95% CI [0.800. 0.937]).Conclusions:The Spanish CAPA questionnaire is a valid and reliable tool for assessing breastfeeding basic competence among primary care professional groups who attend lactating mothers.

Background:Despite increasing breastfeeding initiation rates in the United States, disparities in breastfeeding continuation and exclusivity by race and ethnicity persist.Research Aim:We aimed to understand the perceptions and experiences of Latina parents who received access to telelactation, and assessed the implications of integrating telelactation into pediatric settings.Methods:This cross-sectional qualitative study drew from participants enrolled in a randomized controlled trial about breastfeeding support. We recruited 20 participants from among those participating in a randomized controlled trial assessing the effect of telelactation on breastfeeding outcomes. The study design was informed by an Equity-Centered Model and authentic entry. We conducted a thematic content analysis through an iterative approach, where we systematically generated themes to describe code application patterns.Results:We identified three themes: (1) telelactation within the broader landscape of breastfeeding support; (2) perceptions of telelactation support; and (3) recommendations on the use of telelactation in the context of pediatric care. We found that participants had an escalation approach for seeking breastfeeding support and propose a new model: Breastfeeding Support Escalation Protocol, which can be applied to lactation support in pediatric care. Parents’ perceptions and recommendations highlighted their desire for care coordination, expanded options for telelactation engagement, and care continuity, which are important reflections for pediatric offices considering integrating telelactation services into their practice.Conclusions:Latina parents found telehealth to be helpful and an acceptable alternative to in-person services. Pediatric offices can take steps toward becoming Breastfeeding-Friendly by partnering with telelactation services. More research is needed on the logistical implications and cost-effectiveness of telelactation services as part of the pediatric practice.

Background:Human milk feeding rates in the United Kingdom are a public health concern. Changes to United Kingdom policy and practice are needed to improve lactation support. These should be informed by those with lived experience of human milk feeding and those who provide support.Research Aim:The aim of this study was to identify research, policy, and practice priorities for increasing human milk feeding rates using insights from a wide range of stakeholders. A secondary aim was to evaluate the influence of a World Café on individual attendees and their interactions within the organizations and communities of which they are a part.Methods:The research employed a participatory qualitative design, incorporating a cross-sectional survey and World Café discussions. World Café is a novel approach to engaging stakeholders in discussion, resulting in consensus-building and participatory-driven recommendations. A pre-event survey was completed by a self-selected sample of 67 participants; 37 of these (55%) took part in World Café discussions or an online focus group. World Café discussions and the online focus groups were recorded and transcribed verbatim. Following the World Café, 12 participants (32%) completed a post-event survey, and eight (22%) completed an additional follow-up survey at 2 months.Results:Priority policy and practice changes were identified, including enhancing education, the need for dedicated funding for human milk feeding support, the need to include family within support provision, and the need to change policy regarding media representations of infant feeding. In addition, World Café methodology proved valuable for facilitating networking and instigating changes in relation to support.Conclusion:World Café generated stakeholder agreed-on priorities for research and policy. Many of the recommendations from historical policy and guidance continue to be areas for further development.
