A descriptive analysis of human milk dispensed by the Leipzig Donor Human Milk Bank for neonates between 2012 and 2019

Background

Human milk banking has become an important aspect of Nutritional medicine. It is not just about the provision of mother's own milk (MOM) or donor human milk (DHM) in the hospital, but also a strategy to encourage breastfeeding in the clinical setting and beyond.

Objective

To describe the feeding patterns of hospitalised infants including human milk dispensed by the Leipzig Donor Human Milk Bank (LMB).

Design

A descriptive analysis of daily data on milk feeds dispensed by LMB for hospitalised infants distinguishing between MOM or DHM, either fresh or frozen, and raw/pasteurised milk from 2012-2019.

Results

We included 2,562 infants with median hospitalisation of 23 days, for whom human milk was dispensed on median 76% of those days and other nutrition on the remaining days. Raw MOM and raw DHM comprised 52% and 8% of the dispensed milk, respectively. Dispensing exclusive DHM instead of MOM for at least one full day was required for 55% of the infants, mostly at the beginning but also later during hospitalisation. Exclusive raw DHM was dispensed on at least 1 day for 37% of the infants, in different birthweight strata <1,000 g: 10%, 1,000-1500 g: 11%, 1,500-2500 g: 13% and > 2,500 g: 3%. At discharge, MOM was dispensed for more than 60% of the infants.

Conclusion

During an infant's hospital stay, LMB dispenses various human milk feeds with interspersed DHM resulting in complex intra-individual and time-variant feeding patterns. LMB dispenses raw MOM and especially raw DHM with the intention to retain the properties of human milk unlike a diet containing pasteurised DHM and/or formula. Although raw DHM comprises a small percentage of all dispensed milk, raw DHM is dispensed for a substantial portion of infants. Our results document that dispensing raw DHM, is possible in routine settings.

Women's Experiences of Infant Feeding Practices While Living With HIV in Malaysia: A Community-Based Qualitative Study

BACKGROUND

With the advancement of antiretroviral therapy scale-up, it is possible for women living with HIV to breastfeed safely. However, this practice has not been adopted in Malaysia. Instead, infants are provided with subsidized human milk substitutes for their first 2 years of life.

RESEARCH AIM

This study describes the infant feeding experiences of women living with HIV in Malaysia.

METHODS

From August to October 2021, a nationwide, community-based qualitative study was conducted among women living with HIV and who received care from the Malaysian Ministry of Health. Using purposive sampling, participants who met the inclusion criteria were recruited. Interview and focus group transcripts were coded based on a secondary thematic analysis.

RESULTS

Six in-depth interviews and five focus group discussions were conducted among 32 participants. Study participants were mostly Malay secondary school graduates in their 30s and 40s. Due to the fear of vertical transmission, which was explained by healthcare providers to the participants, none of the women breastfed their infants. The three primary themes that emerged from analyzing the women's infant feeding experiences were (1) a human milk substitute was the only option and was encouraged; (2) feeding infants with a human milk substitute made the women feel incomplete as mothers; and (3) the women encountered difficulties in obtaining the subsidized human milk substitute.

CONCLUSION

Women living with HIV in Malaysia have been advised to provide human milk substitutes to their infants in fear of HIV transmission.

Infant Feeding Practices and Social Support Networks Among Immigrant Chinese American Mothers With Economic Disadvantage in New York City

BACKGROUND

Maternal social support promotes healthy infant feeding practices, which influence healthy growth and development. Less is known about how the interplay of social support networks and multicultural health beliefs may influence infant feeding practices, particularly among immigrant Chinese American mothers with economic disadvantage and low breastfeeding rates.

RESEARCH AIM

To explore the role of social support networks in the development of infant feeding practices in immigrant Chinese American mothers with infants.

METHODS

This was a prospective, cross-sectional qualitative study where we conducted semi-structured interviews in Mandarin, Cantonese, or English with Chinese American mothers of infants (N = 25) at a federally qualified health center in the Sunset Park neighborhood of Brooklyn, New York. Data were analyzed by a multicultural, multidisciplinary team using qualitative thematic analysis and the constant comparative method to identify and iteratively refine emerging codes.

RESULTS

Three themes emerged describing how broad transnational communities and close family and friends influence maternal-infant feeding practices: (1) Gathering and processing infant feeding information from broad transnational resources (i.e., from both the mother's country of residence and the mother's country of origin); (2) aligning maternal feeding attitudes with cultural health beliefs of local social networks; and (3) gaining confidence with transactional maternal-infant feeding interactions.

CONCLUSIONS

Strategies to promote healthy infant feeding should consider how family supports and culturally-relevant coaching can help align multilevel transnational social networks with healthy infant feeding practices.

Fecal Bacterial Communities Differ by Lactation Status in Postpartum Women and Their Infants

BACKGROUND

Previous research examined effects of human milk on the infant gut microbiota, but little attention has been given to the microbiota of lactating women.

RESEARCH AIM

To determine associations between exclusive human milk feeding and gut microbiota characteristics in mothers and infants at 6-weeks postpartum.

METHODS

A sample of mother-infant dyads (N = 24) provided fecal samples and questionnaire responses at 6-weeks postpartum as part of the Pregnancy, EAting & POstpartum Diapers study. Deoxyribonucleic acid was extracted from stool samples, followed by (V4) 16S ribosomal ribonucleic acid gene amplicon sequencing. Alpha and beta diversity, in addition to taxa differences, were compared by human milk exposure status, exclusive versus non-exclusive. A subset of dyads (those exclusively fed human milk; n = 14) was analyzed for shared bifidobacterial species using polymerase chain reaction.

RESULTS

Alpha diversity was significantly lower in exclusively human milk-fed infants. Maternal lactation status (exclusive vs. partial) and Shannon diversity were associated in univariate analysis but were no longer associated in multivariable regression including body mass index category in the model. Beta diversity (Sorensen dissimilarity) of fecal samples from women and infants was significantly associated with human milk feeding. Of six infants with Bifidobacterium longum subspecies longum in their fecal samples, all their mothers shared the same species.

CONCLUSION

Maternal gut microbiotas differ by lactation status, a relationship potentially confounded by body mass index category. Further research is needed to identify whether lactation directly influences the maternal gut microbiota, which may be another mechanism by which lactation influences health.

"…[T]his is What We are Missing": The Value of Communicating Infant Feeding Information Across Three Generations of African American Women

BACKGROUND

Breast/Chestfeeding remains a public health issue for African Americans, and increased rates would mitigate many health disparities, thus promoting health equity.

RESEARCH AIMS

To explore the interplay of generational familial roles and meaning (or value) ascribed to communicating infant feeding information across three generations.

METHOD

This prospective, cross-sectional qualitative study used an asset-driven approach and was guided by Black Feminist Thought and Symbolic Interactionism. African American women (N = 35; 15 family triads/dyads), residing in the southeastern United States were interviewed. Data were analyzed using thematic analysis.

RESULTS

The older two generations described their role using assertive yet nurturing terms, while the younger generation carefully discussed the flexibility between their familial roles. Emergent themes described the meaning each generation attributed to communicating infant feeding information: "My Responsibility," "Comforting," "Bonding Experience," "She Cared," and "Gained Wisdom."

CONCLUSIONS

Our findings have potential to contribute to achieving health equity in African American families. Future breast/chestfeeding promotion efforts may benefit from reframing the current approach to including protection language and not solely support language. Lactation professionals should further recognize and support strengths and resource-richness of intergenerational infant feeding communication within African American families using strength-based, empowerment-oriented, and ethnically sensitive approaches.

Community Perspectives During a Lead Contaminated Drinking Water Crisis: Lessons for Lactation and Other Health Providers

BACKGROUND

Millions of people today live in contaminated environments. Often, these environments disproportionately affect nonwhite, racialized families who are low-income, pregnant, and/or feeding young children. Despite the overwhelming recognition among scholars and practitioners of these realities, however, few lactation or other health professionals center socially disadvantaged families' perspectives in their work. Community expertise is therefore often absent from the credentialed lactation and associated support that tends to be advanced in contaminated environments.

RESEARCH AIMS

The aims of this study were to: (1) Describe how vulnerable community members experience toxic environments, and (2) Explore the strategies vulnerable community members themselves employ and seek out from professionals to achieve resilience in these environments.

METHODS

The research design for this study was prospective and cross-sectional. We surveyed 62 Milwaukeean African American women of childbearing age and their close networks of support from predominantly low-income census tracts, and we engaged 14 women in a community conversation on their experiences, strategies, and desires generated from living in Milwaukee during a lead contaminated drinking water crisis.

RESULTS

Participants were aware and concerned about toxic poisoning in their environment, especially as it affects their children. Nonetheless, societal factors constrained their levels of preparedness and action in response, including around chestfeeding, breastfeeding, expressed milk feeding, and artificial feeding methods.

CONCLUSION

Lactation providers and other health professionals can better support at-risk families by integrating their perspectives into dominant frameworks for information-sharing, preventative resource distribution, and supporting community self-determination.

Characterization of Infant Feeding Practices and Related-Family Characteristics in the French Nationwide ELFE Birth Cohort

Family characteristics such as education level or income are related to infant feeding practices. This study aimed to characterize infant feeding practices and investigate their associations with family characteristics. Analyses were performed with data from a French nationwide cohort, Etude Longitudinale Française depuis l’Enfance (ELFE). Feeding practices were characterized by two methods, a principal component analysis and a hierarchical ascendant classification (n = 8922). This characterization was conducted in three steps: considering firstly only introduction of main food groups, then also food pieces and finally adding the type of complementary food. The associations between family characteristics and the infant feeding patterns or clusters were tested by linear or multinomial regressions (n = 7556). Besides breastfeeding duration and age of first introduction of complementary foods, it appeared also important to consider specific food groups such as sweetened beverages and cow’s milk, and the introduction of food pieces, to describe feeding practices. Recommended feeding practices (longer breastfeeding, complementary food in the right period) were related to higher maternal age and education level, so was migration status, the presence of older children, low income or the mothers’ attendance to pre-birth preparation classes. The interrelations between feeding practices and family characteristics must be considered when examining the influence of feeding practices on child’s health.

Back to the Breast: An Historical Overview of the Perceived Connections Between Sudden Infant Death Syndrome and Breastfeeding

In the late 19th century, physicians in the United States and Europe grew concerned about an increasingly visible subset of infant mortality: sudden infant death. Over the next 100 years, physicians worked variably to combat the problem, modifying and refining their conceptions of sudden infant mortality many times over the process. Physicians' overlapping revisions of sudden infant mortality ultimately helped to produce the categorization of Sudden Infant Death Syndrome (SIDS), and their ensuing, fluctuating efforts to resolve this problem shed light on social and medical perceptions of the roles that biology, the environment, and infant care practices played in sudden infant death. SIDS's official medical classification was a watershed; not only did the formal medical label establish its "authenticity" as a medical phenomenon, but the label also asserted the inexplicability of (at least some) sudden infant death episodes while simultaneously conveying that affected parents were deserving victims of a tragic loss. In the modern history of sudden infant death in the United States, breastfeeding, in particular, was understood variably as a possible cause for unnecessary infant mortality in the decades surrounding 1900; inconsequential to the occurrence of SIDS in the mid 1900s; and finally as an important and healthful way to reduce the risk for SIDS beginning in the late 1900s.

Neonatal Eating Assessment Tool-Breastfeeding: Reference Values for Infants Less Than 7 Months old

BACKGROUND

The Neonatal Eating Assessment Tool-Breastfeeding is a valid and reliable 62-item parent-report assessment of symptoms of problematic breastfeeding behavior intended for infants less than 7 months old.

RESEARCH AIM

The aim of this study was to describe the Neonatal Eating Assessment Tool-Breastfeeding total score and subscale scores within a sample of full-term, healthy, typically-developing infants under 7 months old.

METHODS

Parents of healthy, full-term breastfeeding infants (N = 475) less than 7 months old completed the Neonatal Eating Assessment Tool - Breastfeeding through an online survey. Descriptive statistics were calculated for the total score and seven subscale scores within each age group: 0-2, 2-4, 4-6, and 6-7 months.

RESULTS

Neonatal Eating Assessment Tool-Breastfeeding total scores were highest (i.e., more problematic symptoms) at 0-2 months and decreased in older infant age groups. All subscale scores also had a downward trajectory in symptoms of problematic breastfeeding except the subscale Compelling Symptoms of Problematic Feeding, which was very low across age groups. Scores on the Infant Regulation subscale remained elevated for the first 6 months of life, then declined markedly in the 6-7 month age group.

CONCLUSION

The Neonatal Eating Assessment Tool-Breastfeeding now has reference values to facilitate interpretation of scores and guide decision-making, personalization of interventions, and assessment of response to interventions. For research, the Neonatal Eating Assessment Tool-Breastfeeding can be used to follow longitudinal development of breastfeeding as well as to test efficacy of breastfeeding interventions.

Toward Consistency: Updating Lactation and Breastfeeding Terminology for Population Health Research

There has, historically, been a lack of consistency in the use and definition of terms and their associated measurement in breastfeeding research. The purpose of this paper is to promote consistency through a taxonomy and lexicon for population-based breastfeeding research with the modern nursing dyad. The taxonomy organizes concepts in categories related to research on feeding human milk to infants, noting the perspective from the provider of human milk (parent or alloparent) and the receiver of human milk (child). The taxonomy includes these categories: psychology, physiology, behavior, and modality. The intensity of behaviors and modalities can be characterized qualitatively or quantitatively. Other terms are introduced or defined for the modern era and measurement standards are posed. These suggestions invite discussion and debate, in an effort to move researchers toward consistent measurement, documentation, and presentation, to build a credible evidence base for breastfeeding and practices related to the provision and consumption of human milk.

A Case Study of Biological Nurturing

INTRODUCTION

This case of a mother and her two children, born 20 years apart, highlights how Biological Nurturing (BN) supported a woman in meeting her personal breastfeeding goals. We know lack of breastfeeding support contributes to early weaning. Applying the principles of BN (unrestricted and laid-back breastfeeding) enabled this mother to return to breastfeeding without supplements.

MAIN ISSUE

After giving birth to her first son prematurely in 1997, the dyad was separated, and formula introduced. These interventions, combined with inadequate breastfeeding support, resulted in low milk supply and unplanned weaning by week six. In 2017, a full term sibling baby girl was born, with breastfeeding again beginning with concerns of low milk supply.

MANAGEMENT

Consultation with an International Board Certified Lactation Consultant successfully addressed common breastfeeding problems, including vasospasm and insufficient milk supply. Continuous emotional support helped this mother overcome perceived insufficient milk supply. Introducing BN led to breastfeeding without supplementation, by enabling the dyad to experience enjoyment, comfort and feeding autonomy.

CONCLUSION

While the repeated experience of insufficient milk supply two decades apart constituted a psychological barrier to exclusive breastfeeding, BN enabled reaching this mother's breastfeeding goals. BN appears to be a powerful tool for both breastfeeding initiation and overcoming breastfeeding difficulties, potentially setting new best practice standards.

Weight-Related Concerns as Barriers to Exclusive Breastfeeding at 6 Months

BACKGROUND

Human milk is considered the gold standard for infant nutrition, but more data are needed that examine the constellation of weight-related concerns as barriers to exclusive breastfeeding.

RESEARCH AIMS

The aim of this study was to examine how mothers' concerns regarding their own and their infants' weight, as well as disordered eating behaviors, were associated with breastfeeding self-efficacy and exclusive breastfeeding at 6 months.

METHODS

A prospective, quantitative, and self-report online survey design was used. Participants included 206 women (88.30% White, 59.20% with graduate degrees), with a mean age of 33.04 years ( SD = 4.31 years) and a mean prepregnancy body mass index (BMI) of 24.80 kg/m² ( SD = 5.50 kg/m²), who had given birth within the past 6 months.

RESULTS

Participants who reported not exclusively breastfeeding at 6 months had significantly higher prepregnancy BMI ( p < .001), higher body dissatisfaction ( p = .003), more disordered eating ( p = .036), higher child weight concerns ( p < .001), and lower breastfeeding self-efficacy ( p < .001). Mediation modeling revealed a direct negative relationship between prepregnancy BMI and exclusive breastfeeding at 6 months ( p < .001). Indirect negative relationships between prepregnancy BMI and exclusive breastfeeding at six months via (a) body dissatisfaction, (b) disordered eating, and (c) child weight concern, as well as breastfeeding self-efficacy (entered as concurrent mediators), were all significant.

CONCLUSIONS

Mothers' weight, body image and eating concerns, concern regarding their children's weight, and breastfeeding self-efficacy may constitute critical barriers to exclusive breastfeeding at 6 months. Interventions to improve breastfeeding duration and confidence should target maternal body image and eating concerns.

Awareness of Breastfeeding Laws and Provisions of Students and Employees of Institutions of Higher Learning in Georgia

BACKGROUND

Over the past 2 decades, southern states in the United States have recorded the lowest breastfeeding rates. It is not known whether awareness of breastfeeding laws and provision of resources play any role in their breastfeeding practices.

RESEARCH AIMS

The aims were (a) to describe awareness of breastfeeding laws and provisions by students and employees of institutions of higher learning in the state of Georgia, (b) to describe awareness by race and ethnicity, and (c) to determine factors associated with awareness of breastfeeding laws and provisions among students and employees within Georgia institutions of higher learning.

METHODS

A cross-sectional online survey of students ( n = 1,923) and employees ( n = 1,311) associated with five institutions within the University System of Georgia ( N = 3,271) was completed. Convenience sampling was used. Data were collected through Qualtrics. Chi-square test was used to examine differences between groups, while logistic regression was used to examine associations.

RESULTS

Participants included 33.3% undergraduate, 26.2% graduate students, 24.6% staff, 14.2% faculty, and 1.7% administrators. Over two thirds were female and white. Almost one third reported having a child or children. Awareness of breastfeeding laws and provisions was very low among respondents, with 26.6 and 9.6% aware of federal and state provisions, respectively. While less than 10% were familiar with the Baby Friendly Hospital Initiative program, 52.6% reported their institution provides a supportive environment for breastfeeding. Being a student and being a minority were negatively associated with awareness of laws and provisions that support breastfeeding.

CONCLUSION

The need for focused efforts on increasing awareness of legislative and institutional provisions and support for breastfeeding exists.

Factors Affecting Breastfeeding Outcomes at Six Months in Preterm Infants

BACKGROUND:

Preterm mother-infant dyads often face many obstacles to breastfeeding. Preterm infants are at highest risk for low rates of exclusive breastfeeding.

RESEARCH AIM:

To determine the prevalence of breastfeeding at 6 months among preterm infants and to identify factors that influenced mothers' breastfeeding practices.

METHODS:

A longitudinal observational study was conducted in a metropolitan hospital in Beijing, China. Mothers ( N = 270) and their preterm infants ( N = 280) were included in the study. Characteristics of preterm mothers and their perceptions of breastfeeding self-efficacy, knowledge, social support, and postpartum depression symptoms were measured at the discharge of neonatal intensive care. Breastfeeding data were collected by phone interview at 6 months corrected age.

RESULTS:

At discharge, mothers of very preterm infants perceived a lower level of breastfeeding self-efficacy (measured with the Breastfeeding Self-Efficacy Scale-Short Form) and had a higher level of depression symptoms (measured with the Edinburgh Postnatal Depression Scale [EPDS]) than mothers of moderate and late preterm infants ( p < .05-.01). Nearly half of all mothers had an elevated EPDS score, considered to be symptomatic of postpartum depression. At 6 months, only 22.5% of all infants were exclusively breastfeeding. Factors associated with exclusive breastfeeding, including younger maternal age, previous breastfeeding experience, shorter mother-infant separation time during intensive care, older infant gestational age, and a higher level of breastfeeding self-efficacy, significantly predicted exclusive breastfeeding practice ( p < .05-.001).

CONCLUSION:

The prevalence of breastfeeding at 6 months for preterm infants in this sample was low. Strategies to improve breastfeeding duration for preterm infants are needed, including support and education of mothers while in the hospital.

"They Lacked the Right Food": A Brief History of Breastfeeding and the Quest for Social Justice

In the late 19th-century United States and Europe, infants died at high rates from diarrhea. Physicians and social justice advocates responded to the public health crisis with attempts to clean up the water and cows' milk supplies, as well as social welfare legislation and assorted educational efforts to help mothers better care for their children. Most visible among the educational efforts were breastfeeding campaigns. A century later in developing countries, physicians and activists were confronted with a similar problem-infants dying from diarrhea due to the unethical advertising and marketing practices of formula companies. I argue in this article that crusades for social justice at the most basic level-to ensure that children will live to adulthood-have long been connected with efforts to safeguard mothers' ability to adequately breastfeed their children.
