Background:Breastfeeding is crucial in providing infants with needed nutrition and immunity to foster their healthy growth and development; yet, optimal support from health workers is critical for it to be successful.Aim:To determine factors influencing tangible breastfeeding support among health workers in Nigeria.Methods:This cross-sectional study was conducted in Nigeria’s six geopolitical zones between August 2022 and February 2023 among health workers (N = 2,922). Data were gathered through an interviewer-administered, validated questionnaire. Significant factors of tangible breastfeeding support were identified through multivariable logistic regression, and corresponding odds ratios with 95% confidence intervals were reported.Results:The mean age of the health workers was 28.6 (SD = 9.3) years. Just 45% (1,316) achieved optimal scores for tangible breastfeeding support. Only 31.4% (918) of lactation support providers/specialists practice tangible breastfeeding support and half (50.6%, 1,479) had a favorable attitude towards providing tangible breastfeeding support. About two-fifths (39.3%, 1,148) engaged caregivers in reviewing breast milk storage procedures, whereas, 54.6% (1,595) and 78.0% (2,279) of health workers assisted with breast pumps and breastfeeding attachment respectively. The odds of having optimal tangible breastfeeding support were higher for health workers aged 52 years or older compared to those aged under 20 years (aOR 1.88, 95% CI [1.13, 3.12]), a positive attitude (aOR 1.43, 95% CI [1.22, 1.69]), availability of a breastfeeding champion (aOR 1.47, 95% CI [1.21, 1.79]), 1.69]), provision of breast-pump videos (aOR; 2.33, 95% CI [1.85, 2.95]), and hand-expression videos (aOR; 1.41, 95% CI [1.02, 1.79]). (duplication)Conclusion:Health workers’ tangible breastfeeding support in Nigeria is suboptimal and is driven by age, service level, attitude, availability of breastfeeding champions, and appropriate practice aids. Targeted interventions to improve health workers’ attitudes, technical skills, provision of aids, and task shifting to non-specialists are needed for optimal tangible breastfeeding support.

Background:While the basic needs of breastfeeding women are similar to those of the general population, there are some specificities that must be taken into account when responding to an emergency.Aim:This study examines the breastfeeding barriers faced during a large earthquake in Türkiye and aims to investigate how infant feeding practices of breastfeeding mothers staying in temporary shelters after the earthquake were affected.Methods:This study follows a qualitative descriptive design with an inductive approach. It included participants who were older than 18 years of age, had babies no older than 1 year, and were breastfeeding mothers when the earthquake struck.Results:Five main themes were identified through a content analysis of the interviews: (1) breastfeeding environment after the earthquake, (2) emotional impact, (3) change in social relationships, (4) physiological needs and problems, (5) specialized maternal and baby health services. Factors affecting mothers’ infant feeding practices were crowded breastfeeding environments, stress and fear caused by the earthquake, decreased breastfeeding support due to changes in social relationships, difficulty in reaching basic physiological needs, and lack of professional health workers in the earthquake region.Conclusion:The most important factor affecting breastfeeding was the lack of suitable environments in which to breastfeed. There should be local, regional, and federal policies to support the privacy needs of displaced breastfeeding mothers.

Photo elicitation is a qualitative data collection technique in which the researcher includes photographs or other visual images as part of participant interviews. The researcher might provide the photographs or might ask the participants to bring photographs to the interview. This technique enhances the breadth and depth of verbal qualitative interviews. The use of photo elicitation can enhance the rigor of a qualitative study. There are both advantages and disadvantages of this data collection technique. Ethical issues warrant special consideration.

Climate change is an urgent threat to perinatal and infant health, with the greatest effects of climate change exposures being felt disproportionately by global majority communities who have been most harmed by systems of oppression. Human milk feeding is one recognized solution to bolster climate resilience. Yet, policies and practices to support human milk as a climate solution are inconsistent and under-prioritized, which is unsurprising given the lack of alignment between human history and current cultural context with regard to lactation and human milk access. This paper presents a new framework on lactation as a climate solution, which is unique in its incorporation of the critical history of cooperative breastfeeding in our species. Rooted in anthropogeny, or the study of human origins, and antiracist principles of lactation, the Allomilk Framework highlights five concepts of the ideal application of human milk as a climate solution, bridging ancient allonursing with present-day lactation and human milk access. These ideal applications—and the proposed development of measures to operationalize them—will advance the field through a shared understanding of the qualities that should be prioritized in the assessment of policies and practices at the intersection of climate resilience and human milk access. Application of the Allomilk Framework to assess and design future policies and practices will advance the field by increasing the potential for climate resilience and climate mitigation while working with—rather than against—the importance of cooperative breastfeeding in human history.

We discuss the evolution and composition of breast milk and briefly describe how mammalian evolution resulted in lactation, which played a crucial role in infant growth and development. We focus on three teleological factors that significantly contribute to breast milk composition: (1) biological sex at birth, (2) gestational age, and (3) circadian rhythms. We also explain how these factors lead to variability in human milk composition. We emphasize the importance of standardizing the definitions of “preterm” and “term” to accurately study the effects of gestational age on milk composition. Finally, we discuss the role of the circadian clock in regulating lactation and the impact of breast milk on fetal and infant sleep. Investigators may integrate these critical factors when designing a research study that involves the collection of breast milk samples. Teleological factors greatly influence milk composition, and these factors may be considered when designing a study that requires breast milk. We provide both the rationale and application of solutions to address these factors.

Background:Donor human milk is recommended when infants are unable to be fed their mother’s own milk or require supplementation. For-profit companies use technologies to create human milk products for infants in the neonatal intensive care setting without consistent guidelines and regulatory frameworks in place. This commercialization of human milk is inadequately conceptualized and ill-defined.Research Aims:The aim of this study is to conceptualize and define the commercialization of human milk and discuss the need for policy guidelines and regulations.Method:Using a concept analysis framework, we reviewed the literature on the commercialization of human milk, analyzed the antecedents and potential consequences of the industry, and developed a conceptual definition. The literature review resulted in 13 relevant articles.Results:There has been a surge in the development and availability of human milk products for vulnerable infants developed by for-profit companies. Commercialized human milk can be defined as the packaging and sale of human milk and human milk components for financial gain. Factors contributing to the commercialization of human milk include an increased demand for human milk, and consequences include potential undermining of breastfeeding. The lack of guidelines and regulations raises concerns of equity, ethics, and safety.Conclusion:The industry is rapidly growing, resulting in an urgent need for consistent guidelines and regulatory frameworks. If left unaddressed, there could be potential risks for donor milk banking, the future of breastfeeding, and infant and maternal health.

Background:The benefits of breastfeeding for mothers and infants are well known. However, in Taiwan, the average breastfeeding rate remains below the World Health Organization recommendations. Breastfeeding self-efficacy is a known predictor of breastfeeding.Research Aims:To determine: (1) the relationship of sociodemographic factors to prenatal breastfeeding self-efficacy, and (2) the relationship of sociodemographic factors and prenatal breastfeeding self-efficacy to breastfeeding behavior at 8 weeks postpartum among women living in Taiwan.Methods:This was a prospective cohort study of 206 pregnant women collected in an outpatient clinic located in Taiwan. The validated Chinese version of the Prenatal Breastfeeding Self-Efficacy Scale (PBSES) was used to measure self-efficacy for breastfeeding during pregnancy. At 8 weeks postpartum, participants were contacted by telephone to obtain information regarding infant feeding method and duration.Results:The mean age of the pregnant women was 32 years, and the mean prenatal breastfeeding self-efficacy score was 78.6 (SD = 10.6). Scores differed across levels of maternal education, previous breastfeeding experience, and support systems. Prenatal breastfeeding self-efficacy scores were highest among participants reporting spouse support versus other types of support. Maternal age and prenatal breastfeeding self-efficacy were predictive of breastfeeding duration. A 1-year increase in maternal age was associated with a 6% lower likelihood of breastfeeding for at least 2 months postpartum, and a 1-point increase in the prenatal breastfeeding self-efficacy score was associated with a 14% increase in the likelihood of breastfeeding for at least 2 months postpartum.Conclusions:Prenatal breastfeeding self-efficacy may help predict breastfeeding continuation among Taiwanese women in the first 2 months postpartum.

Introduction:The benefits of human milk for preterm infants are well documented. Complex medical conditions can limit the extremely premature infant’s ability to breastfeed and to receive human milk directly, yet these vulnerable infants may benefit most from receiving it.Main Issue:Extremely preterm infants are at risk for infections, digestive challenges, and chronic lung disease, and occasionally require a tracheostomy to facilitate weaning from mechanical ventilation. There is a risk of aspiration when orally feeding a child with a tracheostomy. This case study describes a tertiary neonatal team supporting a family’s direct breastfeeding goal in an extremely premature infant with a diagnosis of bronchopulmonary dysplasia requiring a tracheostomy.Management:Initially, the infant participant (born at 24 weeks and 3 days of gestation, with a birthweight of 540 g) was gavage fed with human milk. The interdisciplinary team collaborated with the family to guide the infant’s feeding goals, providing positive oral stimulation with soothers, oral immune therapy, and frequent skin-to-skin contact to prepare for future oral feeding. Within a month of the tracheotomy procedure, oral feeding was initiated, and direct breastfeeding with the tracheostomy tubing in place was achieved at 50 weeks and 1 day of age as a primary source of nutrition.Conclusion:The open dialogue between the family and healthcare team was the foundation for trialing direct breastfeeding for an extremely premature infant with a tracheostomy. While direct breastfeeding of full-term infants with tracheostomies has been previously described in the literature, this is the first case study of an extremely premature infant with a tracheostomy transitioning to direct breastfeeding.

Background:German-speaking mothers have breastfeeding rates below the international breastfeeding recommendations. Previous research has found that breastfeeding self-efficacy is an important and modifiable predictor of breastfeeding outcomes, thus improving breastfeeding rates. The Breastfeeding Self-Efficacy Scale–Short Form (BSES-SF) is used in many countries to assess maternal breastfeeding self-efficacy. This instrument has not been available in German.Research Aims:To translate the BSES-SF into German and assess its psychometric properties among breastfeeding mothers up to 12 weeks postpartum.Methods:This cross-sectional study was conducted online with 355 breastfeeding mothers recruited from breastfeeding groups through Facebook. The BSES-SF was translated into German using forward and back-translation. To test reliability, item-total characteristics, including Cronbach’s alpha, were examined. We used principal component analysis, as well as known-groups comparisons for evaluating construct validity, and examined the relationship between breastfeeding self-efficacy and demographic variables.Results:The mean age of participants was 32.4 years (SD = 4.32). The Cronbach’s alpha coefficient was .88 and corrected item-total correlations ranged between .37 and .73. Principal components analysis yielded one component with factor loadings >.40 and an eigenvalue of 5.62, which explained 40% of the total variance. In addition, known group comparisons provided further evidence for construct validity. There was no significant difference in BSES-SF scores in terms of demographic and obstetrics characteristics.Conclusion:Our results provide evidence that the German version of the BSES-SF is a reliable and valid tool for measuring breastfeeding self-efficacy among mothers in German-speaking countries.

Pediatricians need to be knowledgeable to adequately carry out their role in the support of breastfeeding, so assessing their knowledge of breastfeeding is vitally important. There are not English language validated questionnaires for pediatricians in the literature; however, in Spanish and Portuguese, there is the Breastfeeding Knowledge Survey (ECoLa, derived from Encuesta de Conocimientos en Lactancia). Our goal is to translate the ECoLa into English. The original survey consisted of true/false questions, including one with an image of a breastfeeding baby, multiple-choice questions featuring clinical cases, and two open-ended short questions. We used a translation approach that incorporated both forward and backward translations and a multidisciplinary committee to evaluate the translation process. During translation, four Spanish versions and seven English versions were considered prior to consensus approval of the final survey. The intraclass correlation coefficient between the English questionnaire and the original Spanish version was 0.85 (95% CI [0.60, 0.95]). A sample of 51 participants completed the survey, resulting in a Cronbach’s alpha of 0.78 for the English version (95% CI [0.70, 0.86]). The Breastfeeding Knowledge Survey is now accessible under a Creative Commons license, permitting its free re-use.

Background:Health professionals need adequate competence to support breastfeeding beyond infancy. There is no established instrument to measure health professionals’ competence regarding long-term breastfeeding. To respond to this shortcoming, the Long-Term Breastfeeding Competence Scale (LBCS) was developed.Research Aim:To develop and pilot an instrument that measures public health nurses’ competence related to breastfeeding beyond 12 months in order to provide adequate breastfeeding counseling for families.Methods:This study was conducted as a cross-sectional online survey on public health nurses working in maternity and/or child health clinics. The relevance and clarity of the LBCS were assessed by an expert panel (N = 6). Public health nurses (N = 197) completed the LBCS, which consisted of a knowledge and skills dimension and an attitude dimension. Descriptive statistics were used to describe the characteristics of the study sample. The conceptual validity of the knowledge and skills dimension was assessed using the dichotomous Rasch analysis, and attitude dimension using the exploratory factor analysis. Internal consistency was evaluated using Cronbach’s alpha. The distribution of the items was summarized by descriptive statistics.Results:According to expert panel evaluations, the LBCS was found to meet the requirements for relevance and clarity (S-CVI 0.90). The internal consistency of the instrument was at a good level (α = 0.796) and met the requirements set for a new instrument.Conclusion:The LBCS is appropriate to determine public health nurses’ competence related to breastfeeding beyond 12 months. The LBCS can be used to identify the need for education concerning breastfeeding beyond 12 months.

Background:Birthmark Doula Collective, a cooperative that provides doula and lactation services in the Greater New Orleans area, mounted an emergency response after two Category 4 storms: Hurricane Laura (2020) and Hurricane Ida (2021). The response included activating a no-cost emergency perinatal and infant feeding hotline. Both disasters coincided with a resurgence of COVID-19 infections in Louisiana.Research Aim:The aim of this study is to understand how an emergency perinatal and infant feeding hotline supported infant and young child feeding in emergencies during hurricanes in Louisiana.Method:This study used a cross-sectional, retrospective qualitative design in a population with low breastfeeding rates. We conducted a content analysis of 97 hotline call logs from Hurricanes Laura and Ida, focus groups with lactation support providers who staffed the hotline during either storm (n = 5), and interviews with mothers who called during Hurricane Ida (n = 2). Focus groups and interviews lasted 30 and 60 minutes, respectively. Transcripts were analyzed using thematic analysis techniques.Results:Call logs revealed infant feeding needs (e.g., mastitis, low milk supply, relactation, and infant formula requests) and non-infant feeding needs (e.g., infant supplies, perinatal and infant care referrals, shelter information). Infant formula was the most requested supply during both hurricanes. Maternal participants discussed family vulnerabilities during Hurricane Ida. Staff described training and strategies to provide support while maintaining their own well-being.Conclusion:Providing a free emergency hotline service is one way to support pregnant and postpartum people and their families seeking infant feeding advice, supplies, and support in the immediate aftermath of a disaster.
