Disparities in Breastfeeding: Impact on Maternal and Child Health Outcomes and Costs

Neighborhood Socioeconomic Status and Breastfeeding Initiation and Duration Among Primiparous Black Women

Background: Social determinants of health account for racial inequities in breastfeeding rates in the United States. There is a gap in the role of neighborhood socioeconomic status (NSES) as it relates to breastfeeding disparities. Methods: Using longitudinal data from the Black Women's Health Study, we assessed associations of NSES with breastfeeding initiation and duration in a cohort of primiparous U.S. Black women. We also explored associations within strata of important economic indicators, including education, occupation, and marital status. Results: Breastfeeding initiation (n = 2,705) increased with NSES quartile, from 75.2% in the lowest quartile to 88.3% in the highest quartile (p < 0.0001). Compared with women living in the highest NSES quartile, those in the lowest quartile had a 41% (odds ratio: 0.59 [95% confidence interval: 0.43, 0.81]) decreased odds of initiating breastfeeding. For breastfeeding duration (n = 2,172), women residing in NSES quartiles 1-3 were significantly less likely (p < 0.0001) to breastfeed (44.4%) for 6+ months compared with those living in the highest quartile (62.8%). Adjusted relative risks for those in quartiles 1-3 compared with 4 (highest) were 0.63 (0.45, 0.87), 0.50 (0.37, 0.68), and 0.64 (0.47, 0.86), respectively (p = 0.0001). There was no statistically significant evidence of effect modification by education, occupation, marital status, and region (Pinteraction = >0.05). Conclusion: Living in a lower NSES environment was associated with reduced breastfeeding initiation and duration compared with a higher NSES environment. Research is needed to understand the mechanisms by which neighborhood-level factors influence breastfeeding initiation and duration for Black women in the United States.

Responses to the 2022 Infant Formula Shortage in the US by Race and Ethnicity

OBJECTIVE

Describe experiences of, and responses to, 2022 infant formula shortages among households with infants aged up to 18 months by race/ethnicity using Household Pulse Survey data.

METHODS

Outcomes included whether households were affected by shortages and, if so, 3 nonmutually exclusive response categories (increased breastmilk, obtained formula atypically, and disruptive coping [disruptions to breastmilk and/or formula]) and 1 mutually exclusive response category (solely disruptive coping). Unadjusted shares reporting each were compared using t tests. Regressions adjusting for household characteristics and fixed effects were used to examine associations between race/ethnicity and the outcomes.

RESULTS

Shares affected by shortages declined over time as the formula supply improved. We found no association between race and ethnicity and reports of being affected by a shortage. Among affected households, non-Hispanic Black households were more likely to report disruptive coping than non-Hispanic White households (P = 0.03).

CONCLUSIONS AND IMPLICATIONS

Shortages may have widened racial/ethnic differences in infant feeding practices. Efforts to inform about infant feeding behaviors, improve access to formula, and/or increase participation in assistance programs could be targeted to those most likely to be affected by unexpected shortages or most likely to resort to disruptive coping behaviors. Further research could examine geographic variation in shortages and their long-term effects on infant feeding behaviors and infant and maternal health.

Association Between Breastfeeding Intensity and Mammary Gland Involution Markers in Early Postpartum Among Women from Low-Income Households

Background: The aim was to examine the associations between breastfeeding intensity and changes in concentrations of mammary gland involution markers (protein and lactose) among mothers participating in federal food assistance programs. Methods: Pregnant women in their third trimester who planned to breastfeed were recruited from local prenatal clinics (n = 25). After delivery, six weekly home visits were conducted to collect human milk samples and 24-hour infant feeding recalls. Milk protein and lactose concentrations were measured utilizing Bicinchoninic Acid and Megazyme assays, respectively. Bivariate tests were carried out using a statistical significance of p < 0.05. Results: Majority (84%) of our participants were either African American or of Latino origin. About one-fourth of our participants were primiparous and the average monthly household income was $3,150 with an average household size of 4. In week 2 postpartum, 18 mothers had a 100% breastfeeding intensity, while in week 6 it decreased to 16 mothers. A significant difference in milk protein concentration was seen between exclusive and mixed-feeding mothers from weeks 2 to 6; meanwhile, for lactose concentrations, the significant differences were seen only in weeks 3 and 4 (p < 0.005). Protein changes were negatively associated with breastfeeding intensity (as breastfeeding intensity went up, protein decreased), while lactose changes were positively associated with breastfeeding intensity (protein r = -0.5578; lactose r = 0.6571). Conclusions: Significant associations between intensity of breast milk feeding and mammary gland involution markers highlight the sensitivity of the mammary gland to mixed feedings in the early postpartum period.

Differences in Breastfeeding Initiation and Duration by Migration History in the Hispanic Community Health Study/Study of Latinos

Objective: To estimate differences in breastfeeding initiation and duration across dimensions of migration history (migration to the U.S. 50 states/District of Columbia [DC] in childhood, adulthood, or not at all) in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Methods: We used data from HCHS/SOL on 520 individuals with a post-baseline live birth and information on breastfeeding collected at Visit 2 (2014-2017). We fit log binomial models adjusted for parity, age at pregnancy, education, income, and immigration history and incorporating sampling weights. Results: Overall, 84% of participants reported initiating breastfeeding and 30% reported breastfeeding for 6 or more months. On average, individuals reported breastfeeding for a median of 88 days (interquartile range: 156). Compared with those born in the U.S. 50 states/DC, individuals born in another country or U.S. territory who arrived in the U.S. 50 states/DC as children (<18 years old) were 2.7 times more likely to initiate breastfeeding (adjusted prevalence ratio 2.7, 95% confidence interval [CI]: 1.4, 4.9) and those who arrived as adults were 2 times more likely to initiate breastfeeding (adjusted prevalence ratio 2.0, 95% CI: 1.1, 3.6). We observed similar patterns for breastfeeding continuation. Conclusions: The timing and duration of life course experiences such as migration are key determinants of breastfeeding behavior among Hispanic/Latina postpartum persons.

Frequency and genotyping of group A rotavirus among Egyptian children with acute gastroenteritis: a hospital-based cross-sectional study

BACKGROUND

This hospital-based cross-sectional study aims to investigate the epidemiologic and clinical characteristics of rotavirus group A (RVA) infection among children with acute gastroenteritis and to detect the most common G and P genotypes in Egypt.

METHODS

A total of 92 stool samples were collected from children under five who were diagnosed with acute gastroenteritis. RVA in stool samples was identified using ELISA and nested RT-PCR. Common G and P genotypes were identified utilizing multiplex nested RT-PCR assays.

RESULTS

RVA was detected at a rate of 24% (22 /92) using ELISA and 26.1% (24 /92) using VP6 nested RT-PCR. The ELISA test demonstrated diagnostic sensitivity, specificity, and accuracy of 91.7%, 100%, and 97.8%, respectively. G3 was the most prevalent G type (37.5%), followed by G1 (12.5%), whereas the most commonly detected P type were P[8] (41.7%) and P[6] (8.2%). RVA-positive samples were significantly associated with younger aged children (p = 0.026), and bottle-fed (p = 0.033) children. In addition, RVA-positive samples were more common during cooler seasons (p = 0.0001). Children with rotaviral gastroenteritis had significantly more frequent episodes of diarrhea (10.87 ± 3.63 times/day) and vomiting (8.79 ± 3.57 times/day) per day (p = 0.013 and p = 0.011, respectively). Moreover, they had a more severe Vesikari clinical score (p = 0.049).

CONCLUSION

RVA is a prevalent cause of acute gastroenteritis among Egyptian children in our locality. The discovery of various RVA genotypes in the local population, as well as the identification of common G and P untypeable strains, highlights the significance of implementing the rotavirus vaccine in Egyptian national immunization programs accompanied by continuous monitoring of strains.

Factors Associated with Provider Counseling Against Breastfeeding in the Setting of Marijuana Use: A Population-Based Survey

INTRODUCTION

The purpose of this study was to explore patient demographic factors associated with counseling against breastfeeding and concurrent marijuana use.

METHODS

A cross-sectional study derived using data from the Centers for Disease Control and Prevention administered Pregnancy Risk Assessment Monitoring System (PRAMS) in collaboration with state and local health departments. This study sample included survey participants whose responses indicate they received counseling discouraging breastfeeding with concurrent marijuana use. Bivariate and multivariate regression analyses assessed the relationship between factors associated with counseling against breastfeeding and concurrent marijuana use.

RESULTS

Of the 10,911 participants in this sample, 9,695 participants who answered the question about receiving counseling discouraging breastfeeding while using marijuana were included in the analysis (89% response rate for the total sample). Twenty nine percent of participants were advised by a provider not to breastfeed while using marijuana. Participants who received this counseling were more likely to be people of color, age less than or equal to 29, with a high school education or less, unmarried, report governmental or no insurance prepregnancy, and report marijuana use postpartum. In the multivariate analysis, age less than or equal to 20 (P = .001), being unmarried (P = .023), and marijuana use postpartum (P = .034) remained associated with counseling against breastfeeding.

DISCUSSION

Our results suggest that individuals are being counseled differently. Unmarried and young people (age <20 years) were more likely to report receiving counseling against breastfeeding with concurrent marijuana use. Given the growing national acceptability of marijuana use, the known benefits of breastfeeding, and the unclear risks of marijuana in human milk, there is a need to standardize counseling to avoid a missed opportunity to educate breastfeeding populations who use marijuana and to reduce the risk of counseling based on providers' personal attitudes and biases not aligned with evidence-based guidelines.

Impact of the 2022 Infant Formula Shortage on Self-Reported Rates of Anxiety and Depression: Evidence from the Household Pulse Survey

PURPOSE

To evaluate the impact of the 2022 infant formula shortage on self-reported anxiety and depression.

BACKGROUND

The US national infant formula shortage of 2022 originated from supply chain disruptions triggered by the COVID-19 pandemic, and the shortage was further compounded by a recall of tainted formula products.

METHODS

We used survey-weighted data from the Household Pulse Survey (HPS) to measure self-reported anxiety and depression among individuals with formula-fed infants less than 1 year of age. We evaluated the association between 2 formula disruption variables (being impacted by the infant formula shortage or having difficulty obtaining formula in the last 7 days) with 2 mental health outcomes (anxiety and depression) using multivariable logistic regressions.

RESULTS

We found increased odds of self-reported anxiety (aOR: 3.13; P < .001) and depression (aOR: 3.05; P = .005) for respondents affected by the infant formula shortage. There were no adjusted associations between having difficulty obtaining formula in the last 7 days and anxiety and depression.

CONCLUSIONS

Individuals affected by the infant formula shortage had increased odds of both anxiety and depression. Continued efforts to improve food security for low-income infants is critical for ensuring equitable nutritional and health outcomes across infant populations.

IMPLICATIONS FOR PRACTICE AND RESEARCH

Continued efforts to reduce food insecurity for low-income infants are critically needed, as infant nutrition impacts caregiver mental health and infant health. Efforts to improve lactation support and breastfeeding initiation are needed in addition to improvements in access to formula.

Breastfeeding Intention and Breastfeeding Postpartum Outcomes between High-Risk and Low-Risk Pregnant Women: A Greek Prospective Cohort Study

BACKGROUND

This prospective cohort study, conducted from pregnancy to six months postpartum and grounded in STROBE methodology, quantitatively explores the relationship between antenatal breastfeeding intentions and subsequent breastfeeding outcomes among high-risk pregnant women, compared to a low-risk pregnancy group.

METHODS

The study was conducted in one of the largest public hospitals in Attica that provides care to pregnant women, enrolling 380 participants divided into high-risk (n = 200) and low-risk (n = 180) cohorts. Data were collected over 20 months (starting from the end of May 2020 until January 2022), spanning from pregnancy to six months postpartum, via comprehensive questionnaires.

RESULTS

Statistical analysis revealed a pronounced correlation between prenatal breastfeeding intentions and actual breastfeeding behaviors across both groups. Specifically, 81.1% of women in the high-risk group and 82.5% in the low-risk group expressed intentions of exclusively breastfeeding during pregnancy. By six months postpartum, 54.9% of the high-risk and 64.3% of the low-risk pregnancy group managed to sustain breastfeeding. Extended antenatal hospitalization emerged as a statistically significant factor (p = 0.045) negatively impacting exclusive breastfeeding intentions among high-risk pregnancies.

CONCLUSION

The findings illuminate the critical influence of antenatal intentions on breastfeeding outcomes, particularly among high-risk pregnancies. Moreover, the study identifies the detrimental effect of prolonged hospital stays on breastfeeding aspirations. These insights underscore the necessity for nuanced, supportive interventions aimed at bolstering breastfeeding rates, thereby advancing maternal and neonatal health objectives aligned with World Health Organization recommendations.

Breastfeeding Intentions among Pregnant Women Enrolled in a Healthy Start Program in Arkansas

INTRODUCTION

Exclusive breastfeeding is recognized as the optimal source of nutrition for infants. Although exclusive breastfeeding rates have increased overall in the United States, substantial inequities exist in breastfeeding among individuals of different socioeconomic statuses, races, and ethnicities. The purpose of this study was to examine characteristics associated with exclusive breastfeeding intentions among pregnant women in Arkansas enrolled in a Healthy Start program.

METHODS

The current study included a cross-sectional design, with a sample of 242 pregnant women in Arkansas enrolled in a Healthy Start program.

RESULTS

The majority of the participants (56.6%) indicated their infant feeding intentions included a combination of breastfeeding and formula feeding. There were substantial differences in breastfeeding intentions among women of different races/ethnicities, with 18.5% of Marshallese women indicating they planned to exclusively breastfeed, compared to 42.1% of White women, 47.6% of Black women, and 31.8% of Hispanic women (p < 0.001). Women over the age of 18 and with higher educational attainment were more likely to intend on exclusively breastfeeding.

DISCUSSION

This is the first study to examine characteristics associated with exclusive breastfeeding intentions among pregnant women in Arkansas enrolled in a Healthy Start program. The study found that race/ethnicity and age were most strongly associated with breastfeeding intentions. These findings are critical to identifying populations for resource allocation and to developing culturally-tailored interventions to help women in Arkansas achieve their desired infant feeding methods.

Clinically Integrated Breastfeeding Peer Counseling to Promote Breastfeeding Equity

OBJECTIVE

This study aimed to determine whether clinically integrated Breastfeeding Peer Counseling (ci-BPC) added to usual lactation care reduces disparities in breastfeeding intensity and duration for Black and Hispanic/Latine participants.

STUDY DESIGN

This study is a pragmatic, randomized control trial (RCT) of ci-BPC care at two ci-BPC-naïve obstetrical hospital facilities in the greater Chicago area. Participants will include 720 patients delivering at Hospital Site 1 and Hospital Site 2 who will be recruited from eight prenatal care sites during midpregnancy. Participants must be English or Spanish speaking, planning to parent their child, and have no exposure to ci-BPC care prior to enrollment. Randomization will be stratified by race and ethnicity to create three analytic groups: Black, Hispanic/Latine, and other races.

RESULTS

The primary outcome will be breastfeeding duration. Additional outcomes will include the proportion of breastmilk feeds during the delivery admission, at 6-week postdelivery, and at 6-month postdelivery. A process evaluation will be conducted to understand implementation outcomes, facilitators, and barriers to inform replication and scaling of the innovative ci-BPC model.

CONCLUSION

This research will produce findings of relevance to perinatal patients and their families, the vast majority of whom desire to provide breastmilk to their infants and require support to succeed with their feeding goals. As the largest RCT of ci-BPC in the United States to date, this research will improve the quality of evidence available regarding the effectiveness of ci-BPC at reducing disparities. These findings will help patients and stakeholders determine the benefits of accepting and adopting the program and inform policies focused on improving perinatal care and reducing maternal/child health disparities. This study is registered with Clinical Trial (identifier: NCT05441709).

KEY POINTS

· Ci-BPC can promote racial breastfeeding equity.. · Ci-BPC has not been tested as a generalized lactation strategy in prior trials and is underused.. · This RCT will identify if ci-BPC can reduce breastfeeding disparities for Black and Hispanic patients..

The role of clinic-based breastfeeding peer counseling on breastfeeding rates among low-income patients

BACKGROUND

Despite the benefits of breastfeeding (BF), rates remain lower than public health targets, particularly among low-income Black populations. Community-based breastfeeding peer counselor (BPC) programs have been shown to increase BF. We sought to examine whether implementation of a BPC program in an obstetric clinical setting serving low-income patients was associated with improved BF initiation and exclusivity.

METHODS

This is a quasi-experimental time series study of pregnant and postpartum patients receiving care before and after implementation of a BPC program in a teaching hospital affiliated prenatal clinic. The role of the BPC staff included BF classes, prenatal counseling and postnatal support, including in-hospital assistance and phone triage after discharge. Records were reviewed at each of 3 time points: immediately before the hire of the BPC staff (2008), 1-year post-implementation (2009), and 5 years post-implementation (2014). The primary outcomes were rates of breastfeeding initiation and exclusivity prior to hospital discharge, secondary outcomes included whether infants received all or mostly breastmilk during inpatient admission and by 6 weeks post-delivery. Bivariable and multivariable analyses were utilized as appropriate.

RESULTS

Of 302 patients included, 52.3% identified as non-Hispanic Black and 99% had Medicaid-funded prenatal care. While there was no improvement in rates of BF initiation, exclusive BF during the postpartum hospitalization improved during the 3 distinct time points examined, increasing from 13.7% in 2008 to 32% in 2014 (2009 aOR 2.48, 95%CI 1.13-5.43; 2014 aOR 1.82, 95%CI 1.24-2.65). This finding was driven by improved exclusive BF for patients who identified as Black (9.4% in 2008, 22.9% in 2009, and 37.9% in 2014, p = 0.01).

CONCLUSION

Inpatient BF exclusivity significantly increased with the tenure of a BPC program in a low-income clinical setting. These findings demonstrate that a BPC program can be a particularly effective method to address BF disparities among low-income Black populations.

A review of dairy food intake for improving health for black women in the US during pregnancy, fetal development, and lactation

Pregnancy and lactation are special life stages that require regular nutritional and medical attention to help protect the health of the mother and promote the growth and development of the offspring. Despite an increased focus on maternal and fetal health over the last several decades, the rates of pregnancy-related morbidity and mortality are increasing in the United States (US). On average, Black women who are pregnant or lactating face greater health disparities and birth complications than other racial/ethnic groups in the US. The issues contributing to these disparities are multi-faceted and include sociocultural, economic, medical, and dietary factors. For example, Black women face greater rates of food insecurity, worse access to healthcare, and lower nutrient status when compared to White women. A growing body of research suggests that consuming a healthier dietary pattern is one of the most potent modifiable risk factors associated with improved fertility and reducing pregnancy-related complications. Recent publications have also shed light on the role of dairy foods in improving diet quality and nutrient status among Black women and for impacting maternal and fetal health outcomes, such as preeclampsia, spontaneous abortion, preterm birth, and fetal growth. To support healthy pregnancy and lactation, the current national dietary guidelines recommend the consumption of 3 servings of dairy foods per day. However, the vast majority of Black women in the US are falling short of these recommendations and are not meeting nutrient requirements for calcium and vitamin D. Therefore, strategies that target misconceptions surrounding lactose intolerance and focus on the health value of adequate dairy intake among Black women of child-bearing age may benefit both prenatal and postpartum health. This review presents the current evidence on health disparities faced by pregnant and lactating Black women in the US, and the role of dairy foods in supporting healthy pregnancy, fetal development, and lactation outcomes in this population.

Theory-based antecedents of breastfeeding among pregnant women in the United States

Background

Breastfeeding provides several positive health benefits for the newborn child, yet breastfeeding rates remain low in the United States (US). Theory-based approaches have the potential to improve breastfeeding promotion interventions. Hence, the study examined the correlates of intention to breastfeed among US pregnant women based on the multi-theory model (MTM) of health behavior change.

Methods

Using a cross-sectional design, a 36-item online survey was administered to a nationally representative sample of 315 pregnant women in the US. The instrument was psychometrically validated for face, content, and construct validity by a panel of six experts over two rounds. Further, construct validation was done by confirmatory factor analysis (CFA). Hierarchical regression modeling was employed to explain the intention to start breastfeeding and sustain exclusive breastfeeding for up to six months and with complementary foods for up to 24 months.

Results

Internal consistency using Cronbach's alpha was found to be acceptable. It was found that behavioral confidence and changes in the physical environment positively affected the initiation of breastfeeding (P<0.01; adjusted R2=0.478). All three constructs of MTM namely practice for change, emotional transformation, and changes in the social environment were significant predictors for the sustenance of breastfeeding at six months (P<0.01; adjusted R2=0.591) and at 24 months (P<0.01; adjusted R2=0.347).

Conclusion

Based on the findings of this study it is essential for educators and healthcare providers to design MTM-based interventions to promote breastfeeding among pregnant women in the US.

Best for Whom? Heterogeneous Treatment Effects of Breastfeeding on Child Development

The slogan "Breast is Best" has been popularized by medical organizations and parenting networks to extoll the benefits of breastfeeding, yet the causal effects are widely debated. Our study contributes to the debate by examining whether breastfeeding has differential effects based on the propensity to breastfeed, which is also known as causal effect heterogeneity. Prior studies attempt to isolate the causal effect of breastfeeding by netting out confounding characteristics, but we argue that the effects of breastmilk are unlikely to operate in a vacuum. The social forces that promote or constrain breastfeeding among different populations in American society can also shape its effects. Using rich intergenerational panel data from the NLSY79 Child and Young Adult cohort (n = 7902), we evaluate heterogeneous treatment effects in the relationship between breastfeeding and child development from ages 4 to 14 using stratification-multilevel propensity score models. We find that breastfeeding is associated with small benefits for behavioral development, math scores, and academic ability among those with the highest propensities to breastfeed. By contrast, its small benefits for reading comprehension and vocabulary are concentrated among children with the lowest propensities to breastfeed. Our findings suggest that the social process of selection into breastfeeding cannot be fully disentangled from its estimated effects. The social context not only shapes who breastfeeds in American society, but also who benefits most.

The economic value of human milk from three cohort studies in Friuli Venezia Giulia, Italy

BACKGROUND

The Mothers' Milk Tool, developed and launched by the Australian National University and Alive & Thrive in 2022, allows to estimate the volume and value of breastmilk using prevalence rates of breastfeeding by month of age from birth to 36 months. The objective of this study was to obtain these estimates for three cohort studies conducted in a region of Italy.

METHODS

Breastfeeding data from three cohort studies carried out in 1999, 2007 and 2016, with follow-up to 12, 24 and 36 months of 842, 400 and 265 children, respectively, were entered into the downloadable version of the tool. Breastfeeding rates charts and tables with estimates of breastmilk production and value for breastfeeding of children aged 0-36 months were produced.

RESULTS

The rates of initiation of breastfeeding were similar in the three cohorts, while the rates of any breastfeeding at subsequent ages increased over the years. The volumes and values of breastmilk per child increased accordingly, from around 130 L (13,000 USD) in 1999, to 200 L (20,000 USD) in 2007, to 226 L (22,600 USD) in 2016. The percentage of lost breastmilk decreased from 67.7% to 55.4% to 43.7%, respectively. Overall, the 1507 mothers of the three cohorts produced an estimated 250,000 L of breastmilk for their children aged 0-36 months. At 100 USD per litre, this would add up to around 25 million USD.

CONCLUSIONS

Our study shows that the Mothers' Milk Tool can be used to estimate per child volumes and values of breastmilk produced and lost at local levels, and to provide simple indicators of the effects of breastfeeding interventions using the percentage of lost breastmilk, where datasets on rates of breastfeeding by month of age are available. The results of such studies can be used to advocate for better and adequately funded programmes for the protection, promotion and support of breastfeeding.

Protective Characteristics of Human Breast Milk on Early Childhood Otitis Media: A Narrative Review

Introduction: Human breast milk (HBM) contains a complex and dynamically changing variety of factors that contribute to the infant's developing immune system's ability to fight upper respiratory tract infections, including otitis media (OM). We sought to summarize the current evidence on the protective characteristics of HBM, through direct or donated feeding, toward early childhood OM. Methods: For this narrative review, we performed a literature search on OM in the context of HBM feeding in the PubMed, Embase, and Google Scholar databases, between January 1, 2008, and July 1, 2023. Results: Immunoglobulin A (IgA) provides a short-term immunity of 2-3 days against otopathogens causing OM. IgA-mediated immunity is effective against OM up to 7 months of age if breastfeeding continues. The role of transferred IgM and IgG in HBM is unclear. Although there is a potential protective value of microRNA, hormones, oligosaccharides, stem cells, and interleukins present in HBM, their role is unclear. Any duration of breastfeeding is superior to no breastfeeding in OM risk reduction, with a big variability among studies (odds ratio 0.23-0.81, depending on the duration). Duration of breastfeeding ≥6 months was found to be the most effective in OM risk reduction, but there was no evidence of continued benefits after 2 years of age. Expressed breastfeeding was not shown to be more beneficial. The protective values of donor HBM against OM are still undetermined. Conclusion: HBM has numerous components that contribute to protection against early childhood OM.

Obesity and Prenatal Intention as Predictors of Meeting Breastfeeding Recommendations in an Urban Birth Cohort

Background and Objectives: Few U.S. women meet the public health recommendations to exclusively breastfeed for 6 months and continue breastfeeding for at least 1-2 years. We compared prenatally collected demographic, health, and breastfeeding support/intention variables to examine how these factors intersect to predict meeting breastfeeding recommendations. Methods: PREVAIL, a CDC-funded birth cohort in Cincinnati, OH, was approved by the IRB at CDC, Cincinnati Children's Hospital, and the hospitals where enrollment (third trimester, 2017-2018) occurred. The prenatal questionnaire captured sociodemographics, pre-pregnancy weight and height, breastfeeding environment, and breastfeeding intention, while health factors were obtained from obstetrical records. Body mass index (BMI) (kg/m2) was categorized as healthy (18.5-24.9), overweight (25-29.9), obesity 1 (30-34.9), and obesity 2+ (≥35). Mothers self-reported date of exclusive and any breastfeeding cessation through quarterly postnatal questionnaires. Random forest was used for variable selection, cross-validated in multivariable logistic models. Results: Analysis included n = 237 mothers with BMI ≥18.5. Random forest identified BMI category, prenatal intention, and insurance type as the most important predictors of meeting breastfeeding recommendations. The resulting logistic models explained >40% of the variance with an area under the curve of ≥0.89 for both recommendations. More than 73% of the risk of not meeting breastfeeding recommendations was attributable to having an elevated BMI or lacking strong breastfeeding intention. Conclusions: In PREVAIL, maternal BMI and prenatal intention explained most risks of not meeting breastfeeding exclusivity and duration recommendations. Our findings suggest efforts to improve breastfeeding exclusivity and duration should focus on strengthening prenatal breastfeeding intention and identifying effective interventions for supporting breastfeeding among mothers with higher BMI.

Impact of COVID-19 Pandemic on Breastfeeding by Family Vulnerability: An Observational Study Based on Record Linkage

Objective: The aim of this study was to assess the impact of the coronavirus disease 2019 (COVID-19) pandemic on breastfeeding, overall and across degrees of family vulnerability. Study Design: A repeated cross-sectional study was conducted based on record linkage analysis of regional administrative databases providing data on breastfeeding prevalence in children, collected at the time of months of age. Breastfeeding data were linked to maternal characteristics to calculate a breastfeeding vulnerability score. Data over a 3-year period were considered as follows: 2019 (prepandemic), 2020 (lockdown and strict COVID-19 control measures), and 2021 (milder COVID-19 control measures). Results: During the study period, 110,925 immunization records were registered; data on breastfeeding were available for 107,138 records. The prevalence of full breastfeeding at 3 months of age decreased from 57.1% in 2019 to 56.1% in 2021 (p-value = 0.003), whereas prevalence of full breastfeeding at 5 months of age increased (from 44.1% in 2019 to 47.6% in 2021; p-value <0.001). The vulnerability score was calculated for the 70,253 records (63.3% of the initial sample) for which data were accessible: 5% of the sample was in the lowest vulnerability class and 15% in the highest one. As the vulnerability score increased, the prevalence of full breastfeeding at 3 and 5 months of age decreased in each of the three study years. Breastfeeding prevalence within each vulnerability class was not affected by the pandemic. On the other hand, the percentage of children in the high vulnerability class (score ≥3) increased by 3.6% in 2021 compared with 2019. Conclusions: The pandemic has not significantly impacted the prevalence of breastfeeding (-1% at 3 months and +3.5% at 5 months), but the proportion of children in the most vulnerable class increased significantly: action should be taken to ensure that during crises or emergencies the most vulnerable groups receive increased breastfeeding protection, promotion, and support.

Associations Between Breastfeeding and Post-perinatal Infant Deaths in the U.S

INTRODUCTION

Initiation of breastfeeding has been associated with reduced post-perinatal infant mortality. Although most states have initiatives to protect, promote, and support breastfeeding, no analysis of the association between breastfeeding and infant mortality has been conducted at the state and regional levels. To understand the associations between breastfeeding and post-perinatal infant mortality, the initiation of breastfeeding with post-perinatal infant mortality was analyzed by geographic region and individual states within each region.

METHODS

This study was a prospective cohort analysis linking U.S. national birth and post-perinatal infant death data for nearly 10 million infants born in 2016-2018, who were then followed for one year after birth and analyzed in 2021-2022.

RESULTS

A total of 9,711,567 live births and 20,632 post-perinatal infant deaths from 48 states and the District of Columbia were included in the analysis. The overall AOR and 95% CIs for breastfeeding initiation with post-perinatal infant mortality was 0.67 (0.65, 0.69, p<0.0001) for days 7-364. All seven U.S. geographic regions had significant reductions in postperinatal infant deaths associated with breastfeeding initiation; Mid-Atlantic and Northeast regions had the largest reductions with AOR of 0.56 (95% CI=0.51, 0.61, p<0.001 and 0.50, 0.63, p<0.001, respectively), whereas the Southeast had the smallest reduction with AOR of 0.79 (95% CI=0.75, 0.84, p<0.001). Statistically significant results were noted for 35 individual states for reduction in total post-perinatal infant deaths.

CONCLUSIONS

Although regional and state variation in the magnitude of the association between breastfeeding and infant mortality exists, the consistency of reduced risk, together with existing literature, suggests that breastfeeding promotion and support may be a strategy to reduce infant mortality in the U.S.

Evaluation of Commercially Available Infant-feeding Mobile Applications Using App Quality Evaluation Tool

OBJECTIVE

Assess the quality of free, commercially available infant-feeding mobile applications (apps) and their appropriateness for audiences with low income and of racial and ethnic diversity using the App Quality Evaluation tool.

METHODS

Researchers selected apps using an iterative process (n = 6). Health professionals (n = 10) who work with mothers with infants and low income who completed the App Quality Evaluation tool for each app, consisting of 7 domains of app quality. Average domain scores were calculated for each app (> 8 indicates high quality).

RESULTS

Evaluators highly rated app function and purpose for WebMD Baby (8.0 ± 1.8 and 8.2 ± 0.9, respectively) and Baby Center (8.0 ± 2.1 and 8.0 ± 2.6, respectively). For other apps, no domains were highly rated. No apps were rated highly for appropriateness (range 5.7-7.7) nor provided high-quality infant-feeding information for mothers with low income. Few apps were rated highly appropriate for mothers who are Black or Hispanic.

CONCLUSIONS AND IMPLICATIONS

Commercially available infant-feeding apps are of limited quality, indicating the need to develop high-quality apps for audiences with low income and Black and Hispanic identities.

Social Media Usage as a Form of Breastfeeding Support Among Black Mothers: A Scoping Review of the Literature

INTRODUCTION

Social support has been identified in the literature as a key facilitator of breastfeeding success among Black mothers. Over the past decade, there has been a surge of social media groups that can now be used as a means of support for various health and social issues. Social media breastfeeding groups have been used as sources of additional support. A scoping review of the literature was conducted to explore social media usage as a form of social support among Black women in the postpartum period and how it may affect breastfeeding behaviors.

METHODS

Using the 5-stage scoping review methodology, scholarly databases were searched for relevant articles. English-language articles on studies conducted both in and outside of the United States were included. Original studies that focused on social media as a form of breastfeeding support and included Black mothers as part of the study population were included.

RESULTS

After screening 551 articles, 6 studies fulfilled the study criteria. Participants reported being provided with various forms of social support through social media within the included articles. Primary themes included (1) a sense of community and (2) self-efficacy and empowerment. Breastfeeding support through social media appears to positively influence breastfeeding intention and duration rates among Black mothers.

DISCUSSION

Social media is an accessible avenue for breastfeeding information and support. Moreover, it provides a safe space for Black women to interact with others of shared cultural experiences. Therefore, incorporating social media into breastfeeding interventions can positively affect breastfeeding rates among Black women. More research is needed to assess the direct effect of social media breastfeeding support groups on the breastfeeding behaviors and experiences of Black women.

Rethinking breastfeeding management: A patient-centered approach based on new guidelines

The American Academy of Pediatrics (AAP) now recommends exclusive breastfeeding for the first 6 months of life. Nationally, however, breastfeeding rates are low, with Black infants among the least likely to be breastfed. The updated AAP breastfeeding policy guidelines emphasize an urgent need for a patient-centered approach to cultivate awareness of breastfeeding benefits and promote equitable care.

Impact of maternal factors, environmental factors, and race on necrotizing enterocolitis

Necrotizing enterocolitis (NEC) is a complex disease with a multifactorial etiology. As the leading cause of intestinal morbidity and mortality among premature infants, many resources are being dedicated to neonatal care and molecular targets in the newborn intestine. However, NEC is heavily influenced by maternal and perinatal factors as well. Given its nature, preventive approaches to NEC are more likely to improve outcomes than new treatment strategies. Therefore, this review focuses on maternal, environmental, and racial factors associated with the development of NEC, with an emphasis on those that may be modifiable to decrease the incidence of the disease.

Changes in Breastfeeding and Lactation Support Experiences During COVID

Background: We surveyed parents who gave birth from 2019 to 2021 to examine changes in breastfeeding experiences and professional and lay breastfeeding support services due to the coronavirus disease 2019 (COVID-19) pandemic. We also examined racial and ethnic disparities in breastfeeding support. Materials and Methods: A cross-sectional opt-in survey of 1,617 parents was administered on Ovia's parenting app in January 2022. Respondents were 18-45 years of age and delivered in one of three birth cohorts: August-December 2019, March-May 2020, or June-August 2021. We fit linear and logistic regression models wherein the outcomes were six breastfeeding support and experience measures, adjusting for birth cohort and respondent demographics. Results: Parents who gave birth in the early pandemic versus those in the prepandemic had reduced odds of interacting with lactation consultants (odds ratio [OR]: 0.63; 95% confidence interval [CI]: 0.44-0.90), attending breastfeeding classes (OR: 0.71; 95% CI: 0.54-0.94), meeting breastfeeding goals (OR: 0.65; 95% CI: 0.46-0.92), and reporting it was easy to get breastfeeding help (estimate: -0.36; 95% CI: -0.55 to -0.17). Birth cohort was not associated with use of donor milk or receipt of in-hospital help. The later pandemic cohort differed from the prepandemic cohort for one outcome: they were less likely to meet their breastfeeding goals (OR: 0.67; 95% CI: 0.48-0.95). There were racial and ethnic disparities in the use of multiple types of breastfeeding support. Although one-third of respondents felt that the pandemic facilitated breastfeeding because of more time at home, 18% felt the pandemic posed additional challenges including disruptions to lactation support. Conclusions: Parents who gave birth in the later pandemic did not report significant disruptions to professional breastfeeding support, likely as a result of the growth of virtual services. However, disparities in receipt of support require policy attention and action.

Association between Quality of Maternal Prenatal Food Source and Preparation and Breastfeeding Duration in the Environmental Influences on Child Health Outcome (ECHO) Program

This study examined the relationship between maternal food source and preparation during pregnancy and the duration of breastfeeding among 751 mother-child dyads in the United States. The data collected from the Environmental influences on Child Health Outcomes (ECHO) Program included twelve cohorts of mothers (age ≥ 18) who delivered infant(s). Three categories of maternal food source and preparation including, High, Moderate, or Low Food Source Quality were derived from the mother report. The mean duration of breastfeeding differed strongly across the three categories. The High Food Source Quality group breastfed an average of 41 weeks, while shorter durations were observed for the Moderate (26 weeks) and Low (16 weeks) Food Source Quality groups. Cox proportional hazards models were used to estimate the relative hazard of time to breastfeeding cessation for each participant characteristic. The full model adjusted for clustering/cohort effect for all participant characteristics, while the final model adjusted for the subset of characteristics identified from variable reduction modeling. The hazard of breastfeeding cessation for those in the High Food Source Quality group was 24% less than the Moderate group (RH = 0.76; 95% CI, 0.63-0.92). Pregnant women in the High Food Source Quality group breastfed longer than the Moderate and Low groups. We encourage more detailed studies in the future to examine this relationship longitudinally.

Implementation of a Novel Tool to Collect Milk Feeding Data on Infants in Primary Care Clinics

We aimed to capture milk feeding type in real time in a racially and socioeconomically diverse population. An electronic tool to assess milk feeding type at every medical visit for children aged 0 to 2 years was designed and incorporated into nursing workflows. The Milk Box tool was successfully added to the electronic clinical workspace of a large health system. There were eight clinics, with diverse characteristics, which incorporated the use of the Milk Box tool over 12 months. Time to 50% uptake of Milk Box varied from 3 to 5 months. Time to >80% uptake varied from 6 to 8 months. Our results show that Milk Box can be quickly incorporated into a clinical workflow when the team is given appropriate training and support. The tool also allows a primary care practice to study local breast milk consumption trends and to provide both individualized and system-level lactation support.

Work as an Understudied Driver of Racial Inequities in Breastfeeding

Breastfeeding inequities by race are a persistent public health problem in the United States. Inequities in occupation and working conditions likely contribute to relatively less breastfeeding among Black compared to White mothers, yet little research has addressed these interrelationships. Here, we offer a critical review of the literature and a conceptual framework to guide future research about work and racial inequities in breastfeeding. There is a strong public health case for promoting breastfeeding equity for mothers across race groups and occupation types. Existing theory suggests that employment opportunities and working conditions are a likely pathway that connects structural racism to Black-White breastfeeding inequities, in addition to other known factors. We propose a new conceptual model for studying the interrelationships among work, race, and breastfeeding outcomes.

Human milk feeding and wheeze in Black infants born preterm

OBJECTIVES

To determine the association between human milk exposure at 3 months corrected gestational age and recurrent wheeze in preterm Black infants.

METHODS

This is a secondary analysis of data from the D-Wheeze trial (ClinicalTrials.gov identifier NCT01601847). Associations between human milk feeding at 3 months corrected age and wheezing outcomes were examined by generalized linear models.

RESULTS

Exclusively human milk fed infants (n = 13) had significantly fewer wheezing episodes than formula fed infants (n = 230) (IRR (95% CI) = 0.25 (0.07, 0.89), p = 0.03). There were no hospitalizations in infants receiving exclusive human milk. Receiving any human milk was associated with decreased odds of hospitalization by 12 months corrected age (OR (95% CI) = 0.12 (0.02, 0.79), p = 0.03).

CONCLUSIONS

Exclusive human milk feeding at three months corrected gestational age is associated with decreased number of wheezing episodes in the first year of life in preterm Black infants.

Impact of Donor Human Milk in an Urban NICU Population

The American Academy of Pediatrics recommends the use of donor human milk in infants when mother’s own milk is not available. Our objective was to analyze whether the use of donor human milk in preterm, very-low-birth-weight (VLBW, <1500 g) infants affected the rates of necrotizing enterocolitis, duration of parenteral nutrition (PN), growth, culture-positive sepsis, length of hospital stay, and mortality in an urban NICU population with low exclusive breast-feeding rates. A retrospective cohort study was conducted comparing two 2-year epochs of VLBW neonates before and after the introduction of donor breast milk in our neonatal intensive care unit (NICU). With the introduction of donor human milk, there was a significant reduction in the rate of necrotizing enterocolitis (NEC) (5% vs. 13%; p = 0.04) and less severe NEC as defined by Stage III based on the Modified Bell Staging Criteria (10% to 3%; p = 0.04). In the donor milk era, there was earlier initiation of enteral feeding (2.69 days vs. 3.84; p = 0.006) and a more rapid return to birthweight (9.5 days. 10.9 days; p = 0.006). In this study, a change in practice to the use of donor breast milk in a population with low rates of human milk provision was associated with earlier initiation of enteral feeding, faster return to birth weight, and a reduced incidence of NEC.

Association of Exclusive Breastfeeding with Asthma Risk among Preschool Children: An Analysis of National Health and Nutrition Examination Survey Data, 1999 to 2014

Breastmilk contains many important nutrients, anti-inflammatory agents, and immunomodulators. It is the preferred nutrition source for infants. However, the association of the duration of exclusive breastmilk feeding (BMF) with asthma development is unclear. Data on children from the United States who participated in the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2014 were obtained. We examined the association between the duration of exclusive BMF and asthma in 6000 children (3 to 6 years old). After calculating the duration of exclusive breastfeeding according to answers to NHANES questionnaires, the estimated duration of exclusive BMF was divided into five categories: never breastfed or BMF for 0 to 2 months after birth; BMF for 2 to 4 months after birth; BMF for 4 to 6 months after birth; and BMF for ≥6 months after birth. The overall prevalence of asthma in children aged 3 to 6 years was approximately 13.9%. The risk of asthma was lower in children with an exclusive BMF duration of 4 to 6 months (aOR, 0.69; 95% CI, 0.48–0.98), after adjustment for potentially confounding factors. Subgroup analysis revealed that children of younger ages (3 to 4 years old) benefited most from the protective effects of exclusive BMF for 4 to 6 months (aOR, 0.47; 95% CI, 0.27, 0.8). We found that exclusive BMF, especially BMF for 4 to 6 months, is associated with a decreased risk of asthma in preschool-age children. The protective effect appeared to be diminished in older children. The potential mechanism needs further investigation.

The benefits, challenges and impacts of accessing social media group support for breastfeeding: A systematic review

Breastfeeding support is a key component in meeting the public health responsibility of increasing breastfeeding rates, with access to individualised, convenient and linked support across services central to improved outcomes. With the rise of new technology and the COVID‐19 pandemic, social media (SM) support for breastfeeding has become increasingly popular and it is important to understand how and why mothers access such support, and from whom, to optimise services and to meet mothers’ needs. Increasing research is building on women's use and experience of SM for breastfeeding, although there is a paucity of UK data. This systematic review aimed to understand the impacts of SM support for breastfeeding, including benefits and challenges, to establish the evidence for wider provision within maternity services. The search was limited to studies published in English and focused on the self‐directed use of social media groups for breastfeeding (defined as platforms that facilitate group support via interactivity, allowing for user‐generated content and subsequent responses). Of 327 papers retrieved, 13 studies were included for review. The six themes identified were: breastfeeding context, including factors impacting women's decision making; the relational impact of belonging to an online community; increased self‐efficacy; critiques of SM; the nature and types of support commonly sought and received; and breastfeeding duration as an outcome. The findings confirm that mothers value SM groups for community support, which normalises breastfeeding and provides the support they attribute to improved outcomes, and highlight that UK research focused on provision linked to wider services is needed.

Joining a social media (SM) group to seek support is common among those mothers intending to breastfeed. For these mothers SM groups have the potential to provide valued support where it is lacking, or in addition to their existing networks.

SM groups offer reciprocity of knowledge sharing and esteem support. Belonging to a supportive online community promotes emotional wellbeing and self‐efficacy, improving breastfeeding outcomes.

Online peer support is valued and trusted as a complementary source of information and shared experience. Mothers are aware of issues of reliability, lack of regulation and the need to be discerning of online advice.

Factors associated with infant formula supplementation in Brazilian hospitals: a cross-sectional study

OBJECTIVE

To analyze the factors associated with infant formula supplementation in newborns referred to rooming-in in Brazilian hospitals.

METHOD

Cross-sectional study with data from 14,531 postpartum women and newborns obtained from the "Birth in Brazil" survey, conducted in 2011-2012. The analysis used a logistic regression model with a hierarchical approach.

RESULTS

In total, 21.2% newborns received infant formula during hospital stay. After adjustment, the following factors were associated with the use of infant formula: maternal age ≥ 35 years (OR = 1.51; IC95%:1.30-1.75), prenatal care in a private service (OR = 2,22; IC:1.72-2.85)/public and private service (OR = 1.67; IC:1.24-2.23), cesarean delivery (OR = 1.83; IC:1.41-2.38), multiple pregnancy (OR = 3.786; IC:2.02-7.06), non-breastfeeding in the delivery room (OR = 1.780; IC:1.43-2.21), birth in a private hospital (OR = 1.695; IC:1.02-2.79), prematurity (OR = 1.656; IC:1.32-2.06) and extremes of birth weight (< 2.500 g: OR = 2.084; IC: 1.585-2.741/ ≥4,000g: OR = 1.672; IC:1.31-2.11). Teenage age (OR = 0.651; IC:0.55-0.76), low maternal education (OR = 0.579; IC:0.43-0.77), multiparity (OR = 0.588; IC:0.510-0.678), and lower economic class (OR = 0.565; IC:0.41-0.76) significantly reduced the probability of using infant formula.

CONCLUSIONS

Of the associated factors, the authors highlight cesarean delivery and non-breastfeeding in the delivery room, showing that it is necessary to strengthen policies that encourage good practices during childbirth care in order to promote exclusive breastfeeding and protect mothers and newborns from all social classes against the misuse of infant formula.

Exclusive Breastfeeding in the Northwest: Disparities Related to Race/Ethnicity and Substance Use

BACKGROUND AND OBJECTIVES

Mothers who are Black, Indigenous, and people of color (BIPOC) are disproportionately impacted by substance use in pregnancy and less likely to breastfeed. Our objectives were to assess relationships between substance use in pregnancy and exclusive breastfeeding at discharge (EBF) and race/ethnicity and EBF, and determine the extent to which substance use influences the relationship between race/ethnicity and EBF.

METHODS

This is a retrospective cohort study of term mother-infant dyads using 2016 to 2019 data from a Northwest quality improvement collaborative, Obstetrical Care Outcomes Assessment Program. Stepwise and stratified multivariable logistic regression analyses were conducted to determine associations between independent variables consisting of characteristics, including maternal race/ethnicity and substance use, and the dependent variable, EBF.

RESULTS

Our sample consisted of 84,742 dyads, 69.5% of whom had EBF. The adjusted odds of EBF for non-Hispanic Black and Hispanic mothers were half, and for American Indian/Alaska Native mothers two-thirds, that of White mothers (aOR [95% CI]: 0.52 [0.48, 0.57], 0.51 [0.48, 0.54], 0.64 [0.55, 0.76], respectively). Substance use did not mediate the association between race/ethnicity and EBF, but it modified the association. Among those reporting nicotine or marijuana use, Hispanic mothers were half as likely as White mothers were to exclusively breastfeed. Other factors associated with a lower likelihood of EBF included public or no insurance, rural setting, C-section, NICU admission, and LBW.

CONCLUSIONS

Disparities in EBF related to race/ethnicity and substance use were pronounced in this study, particularly among Hispanic mothers with nicotine or marijuana use.

Social Health Care Determinants of Breastfeeding Black Women: A Multigenerational Study

Background: Black women encounter many challenges to breastfeeding, including inequitable access to support and resources and medical racism. However, limited research investigates how Black women across generations interface with health care systems to initiate or continue breastfeeding and what factors facilitate or hinder their breastfeeding experiences. Objective: Using the social determinants of health (SDoH) theoretical framework, this study qualitatively explored how a multigenerational sample of Black mothers' interactions with health care systems facilitated or hindered their breastfeeding initiation and continuation. There were three areas of interest: (1) access and quality, (2) professional and personal support, and (3) literacy and resources. Materials and Methods: Four age cohorts and three breastfeeding length cohorts of Black mothers in Kentucky completed semi-structured interviews on their breastfeeding experiences. Responses to research questions (e.g., "What was your experience during the birthing process and how did it impact your decision to breastfeed?") informed by the SDoH were analyzed using thematic analysis. Results: Four themes emerged on how experiences within health care systems influence Black women's breastfeeding initiation and continuation: (1) health care access, (2) health care quality/bias, (3) health care-related support, and (4) health care resource use. Conclusions: Interpersonal and systemic barriers in health care related to access, quality, support, and resources hindered Black mother's breastfeeding across generations. Mothers across each age and breastfeeding cohorts emphasized a need for culturally tailored pro-breastfeeding health care systems to meet their breastfeeding needs.

Effects of Vaccination Against Influenza, Pertussis, and COVID-19 on Human Milk Antibodies: Current Evidence and Implications for Health Equity

Human milk contains three antibody classes that confer mucosal immunity to the breastfed infant: secretory IgA (SIgA), secretory IgM (SIgM), and IgG. Influenza and pertussis vaccines administered during pregnancy induce pathogen specific SIgA and IgG responses in human milk that have been shown to protect the breastfed infant from these respiratory illnesses. In addition, mRNA vaccines against the SARS-CoV-2 virus administered during pregnancy and lactation induce anti-SARS-CoV-2 IgG and IgA responses in human milk. This review summarizes the immunologic benefits of influenza, pertussis, and COVID-19 vaccines conferred by human milk. Additionally, future research direction in human milk immunity and public health needs to improve lactational support are discussed.

New York State Paid Family Leave Law Associated with Increased Breastfeeding Among Black Women

Background: While breastfeeding has increased during the past 50 years, disparities continue, with Black women having the lowest rates. Use of paid leave has been associated with longer breastfeeding duration. Objective: Evaluate the impact of New York (NY)'s Paid Family Leave (PFL) law on breastfeeding, after it became effective on January 1, 2018. Materials and Methods: Women in NY (excluding NY City), who gave birth in 2016-2019 and completed the Pregnancy Risk Assessment and Monitoring System (PRAMS) survey, were included. Data from PRAMS and the NY State Expanded Birth Certificate were combined. Changes in breastfeeding initiation and duration and use of paid leave were compared, before and after NY's PFL law became effective, with separate analysis by sociodemographic factors. Results: Before NYPFL, Black women were least likely to initiate breastfeeding and breastfed for the shortest duration. After NYPFL went into effect, breastfeeding initiation and duration to 8 weeks increased for Black women, but not for other racial/ethnic groups; these findings persisted after adjustment for sociodemographic factors. Use of paid leave after childbirth increased 15% overall, with greater increases among Black women and Hispanic women. Conclusions: Implementation of the NYPFL law was associated with increased breastfeeding among Black women and increased use of paid leave by all. Greater increases in breastfeeding among Black women significantly reduced breastfeeding disparities by race/ethnicity. More widespread implementation of PFL programs in the United States would promote equity in the use of paid leave, which could reduce disparities in breastfeeding initiation and duration and possibly improve infant and maternal health outcomes.

Technical Report: Breastfeeding and the Use of Human Milk

Breastfeeding and human milk are the normative standards for infant feeding and nutrition. The short- and long-term medical and neurodevelopmental advantages of breastfeeding make breastfeeding or the provision of human milk a public health imperative. The American Academy of Pediatrics (AAP) recommends exclusive breastfeeding for approximately 6 months after birth. Furthermore, the AAP supports continued breastfeeding, along with appropriate complementary foods introduced at about 6 months, as long as mutually desired by mother and child for 2 years or beyond. These recommendations are consistent with those of the World Health Organization (WHO). Medical contraindications to breastfeeding are rare. The AAP recommends that birth hospitals or centers implement maternity care practices shown to improve breastfeeding initiation, duration, and exclusivity. The Centers for Disease Control and Prevention and The Joint Commission monitor breastfeeding practices in United States hospitals. Pediatricians play a critical role in hospitals, their practices, and communities as advocates of breastfeeding and, thus, need to be trained about the benefits of breastfeeding for mothers and children and in managing breastfeeding. Efforts to improve breastfeeding rates must acknowledge existing disparities and the impact of racism in promoting equity in breastfeeding education, support, and services.

The Role of Breastfeeding in Racial and Ethnic Disparities in Sudden Unexpected Infant Death: A Population-Based Study of 13 Million Infants in the United States

Sudden unexpected infant death (SUID) disproportionately affects non-Hispanic Black (NHB) and American Indian/Alaskan Native infants, who have lower rates of breastfeeding than other groups. Using 13,077,880 live-birth certificates and 11,942 linked SUID death certificates from 2015 through 2018, we calculated odds ratios and adjusted risk differences of SUID in infants who were not breastfed across 5 racial/ethnic strata in the United States. We analyzed mediation by not breastfeeding in the race/ethnicity-SUID association. The overall SUID rate was 0.91 per 1,000 live births. NHB and American Indian/Alaskan Native infants had the highest disparity in SUID relative to non-Hispanic White infants. Overall, not breastfeeding was associated with SUID (adjusted odds ratio (aOR), 1.14; 95% confidence interval (CI): 1.10, 1.19), and the adjusted risk difference was 0.12 per 1,000 live births. The aOR of not breastfeeding for SUID was 1.07 (95% CI: 1.00, 1.14) in NHB infants and 1.29 (95% CI: 1.14, 1.46) in Hispanic infants. Breastfeeding minimally explained the higher SUID risk in NHB infants (2.3% mediated) and the lower risk in Hispanic infants (2.1% mediated) relative to non-Hispanic White infants. Competing risks likely explain the lower aOR seen in NHB infants of not breastfeeding on SUID, suggesting that social or structural determinants must be addressed to reduce racial disparities in SUID.

Implementation of the Strategy for Breastfeeding and Complementary Feeding in the Federal District in Brazil

BACKGROUND

The Brazilian Breastfeeding and Complementary Feeding Strategy-Estratégia Amamenta e Alimenta Brasil (EAAB) aims to promote optimal breastfeeding (BF) and complementary feeding (CF) practices through the training of primary health professionals. Competition among health priorities and programs is one of the organizational contextual barriers to consolidating the implementation of the EAAB.

METHODS

This case study included six Primary Health Units (PHU) certified in the EAAB. Documentary analysis, interviews, and surveys were conducted, which informed a conceptual logical model. Organizational context indicators (positive and negative) were identified across the logical model based on the Matus Triangle, and they were used to analyze the degree of implementation of the EAAB in the PHUs.

RESULTS

The logic model elucidated six stages of EAAB implementation, but none on post-certification monitoring. Ten indicators positively influenced the implementation, including having legislation that prioritizes BF and CF. Seven indicators exerted negative influence, especially the lack of specific funding resources for the EAAB. Only one PHU had a consolidated degree of implementation.

CONCLUSIONS

Lack of specific funding, monitoring of BF and CF practices, and compliance with certification criteria are the main challenges for the EAAB's sustainability.

Factors associated with knowledge and practice of optimal breastfeeding among mothers in Dubai

Although breastfeeding has been the primary source of nutrition for infants, many women do not choose to practise breastfeeding due to lack of knowledge, inability to do so or personal choices. This study aimed at determining the breastfeeding practices and examining the sociodemographic factors associated with optimal breastfeeding among mothers attending child welfare clinic at Dubai Health Authority. A structured questionnaire was designed consisting of sociodemographic data, knowledge, attitude and practice towards breastfeeding. The main reasons for not breastfeeding the baby within 30 min after delivery were having had a caesarean section, followed by separation of the baby from the mother. We found better practice among homemakers, non-United Arab Emirates (UAE) and married women, those with less monthly income, and those with standard delivery. There is a need for better education on optimal breastfeeding, especially in UAE national pregnant women, who have had caesarean sections, or having babies admitted in the intensive care unit.

Integrative Review of Antenatal Milk Expression and Mother-Infant Outcomes During the First 2 Weeks After Birth

OBJECTIVE

To explore the practice of antenatal milk expression (AME) and related outcomes for mother-infant dyads during the first 2 weeks after birth.

DATA SOURCES

We searched the electronic databases MEDLINE, Embase, CINAHL, Emcare, Maternity & Infant Care Database, Scopus, and Web of Science for relevant literature. We also conducted backward reference searches on relevant publications and nondatabase searches after review of the full texts.

STUDY SELECTION

Articles were eligible for inclusion if they reported primary studies focused on AME, included samples of mother-infant dyads, and were published in English. We did not impose time or design limitations given the sparse availability of literature on AME. We identified 766 articles. After the removal of duplicates, we screened 588 articles, and of these, we included 15 articles in our review.

DATA EXTRACTION

We used the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) guidelines to guide data extraction and reporting. We evaluated the quality of evidence using the Melnyk and Fineout-Overholt rating system and the Joanna Briggs Institute critical appraisal tools.

DATA SYNTHESIS

We synthesized data from the included articles into four themes: Breastfeeding Self-Efficacy, Milk Supply, Infant Well-Being, and Infant Feeding Methods.

CONCLUSION

AME may support breastfeeding by improving breastfeeding self-efficacy and milk supply and by decreasing early formula use. Synthesized literature on AME shows the safety of the practice and that infants of women who practice AME have a greater likelihood of breastfeeding exclusivity during the short term.

Examination of Factors That Contribute to Breastfeeding Disparities and Inequities for Black Women in the US

Breastmilk is considered the optimal nutrition for newborns. US Black women continue to have the lowest breastfeeding initiation and duration rates. This Perspective examines factors associated with breastfeeding disparities and inequities among Black women through the lens of critical race theory and the social-ecological model. Recommendations to increase breastfeeding rates in this population include increased communication and educational strategies by health care professionals, education to recognize implicit bias and systemic racism in our health care system, early prenatal and ongoing postpartum breastfeeding support, increased community support, and breastfeeding groups developed by and for Black women. In addition, equity policies such as paid maternity leave and work policies that support milk expression would provide needed institutional support for women in the workplace.

Understanding Factors Influencing Breastfeeding Outcomes in a Sample of African American Women

OBJECTIVES

Persistent disparities in breastfeeding rates among African American (AA) women compared to other population groups have motivated researchers to understand factors influencing breastfeeding choices using a variety of methods. Quantitative surveys are more commonly reported, however, qualitative work that amplifies voices of AA women is limited.

METHODS

Participants were recruited from a randomized controlled feasibility trial focused on breastfeeding support for AA women in Detroit, MI. Thirteen women were enrolled in the qualitative portion of the study described here. Using the Socioecological model (SEM) as the theoretical foundation, semi-structured qualitative interviews were conducted to explore perceived facilitators and barriers to breastfeeding. Interviews were digitally recorded, transcribed, and analyzed using Theoretical thematic analysis.

RESULTS

Women reported factors ranging from micro to macro SEM levels that discouraged or reinforced breastfeeding. Key challenges included breastfeeding-related discouragement issues, including factors that decreased confidence and led women to terminate breastfeeding (e.g., problems with latching, pumping, lack of comfort with breastfeeding in public, and work constraints). Facilitators included perceived mother and infant benefits, perseverance/commitment/self-motivation, pumping ability, and social support. Participant suggestions for expanding breastfeeding promotion and support included: (1) tangible, immediate, and proactive support; (2) positive non-judgmental support; (3) "milk supply" and "use of pump" education; and (4) self-motivation/willpower/perseverance.

CONCLUSIONS FOR PRACTICE

Despite the identification of common facilitators, findings reveal AA women face many obstacles to meeting breastfeeding recommendations. Collaborative discussions between women and healthcare providers focused on suggestions provided by AA women should be encouraged.

Differences in Exclusive Breastfeeding Rates in US Hospitals According to Baby-Friendly Hospital Initiative Designation and Area Deprivation Index Category

Background: Disparities in breastfeeding persist placing a greater burden of disease on non-Hispanic black and Hispanic women and infants. Targeted implementation of the Baby-Friendly Hospital Initiative (BFHI) in areas at risk for poor breastfeeding outcomes has been shown to improve disparities in breastfeeding. The area deprivation index (ADI), a measure of the relative socioeconomic disadvantage of a neighborhood, may be useful in exploring the accessibility of BFHI hospitals in highly deprived areas and the differences in exclusive breastfeeding (EBF) rates in hospitals with and without the BFHI designation across deprivation categories. Objective: To evaluate the geographical distribution of BFHI and non-BFHI hospitals across ADI categories and explore the differences in EBF rates in BFHI and non-BFHI hospitals across ADI categories. Methods: Hospital EBF rates obtained from the Joint Commission included 414 BFHI and 1,532 non-BFHI hospitals. State ADI rank scores were determined for each hospital's census block group. Descriptive statistics were used to describe the geographic distribution of BFHI hospitals across three ADI categories (low, medium, and high). EBF rates across ADI categories and BFHI designations were compared using multiway analysis of variance. Results: The distribution of BFHI was similar across all ADI categories, ranging from 18% to 24%. EBF rates were 4.9% lower in highly deprived areas compared to areas with lower deprivation (p < 0.01). BFHI was associated with significantly higher EBF rates across all ADI categories (6.9%-11.2%, p < 0.01). Conclusion: ADI may be a useful tool for targeting the implementation of BFHI in hospitals in highly deprived areas to reduce breastfeeding disparities.

The challenges of medically complex breastfed children and their families: A systematic review

Exclusive breastfeeding for the first 6 months and then alongside solid food for the first 2 years and beyond is the gold standard in young child nutrition. There is an abundance of literature relating to the preventative nature of breastmilk and breastfeeding against many infectious diseases and chronic conditions. However, despite medically complex infants and children being a group that could benefit most from continued breastfeeding, breastfeeding duration and exclusivity are lower among more complex paediatric populations. The reasons for this are not well known, and there is a paucity of data relating to supporting infants who have acute or chronic illness, disability or congenital anomaly to breastfeed. This systematic review aimed to understand the challenges of breast/chestfeeding the medically complex child and to establish the gaps in healthcare provision that act as barriers to optimal infant and young child feeding. The search was limited to studies published in English, focused on breastfed sick infants in hospital, with no date limits as there is no previous systematic review. Of 786 papers retrieved, 11 studies were included for review, and seven themes identified. Themes included practical and psychological challenges of continuing to breastfeed in a hospital setting, complications of the condition making breastfeeding difficult, lack of specialist breastfeeding support from hospital staff and a lack of availability of specialist equipment to support complex breastfeeding. The findings affirm the lack of consistent high-quality care for lactation support in paediatric settings and reinforce the need for further focused research in this area.

Clinically integrated breastfeeding peer counseling and breastfeeding outcomes

OBJECTIVE

To evaluate whether clinically integrated breastfeeding peer counseling (ci-BPC) improved breastfeeding outcomes for a diverse cohort of Medicaid-enrolled patients.

STUDY DESIGN

Medical records were reviewed for a random subset of patients delivering 2014-2015 (baseline, N = 147) and 2017-2019 (post-implementation, N = 281). Chi-squared and logistic regression evaluated differences in breastfeeding initiation, exclusivity, and duration, and results were stratified by race/ethnicity.

RESULTS

Post-implementation, 90.4% of patients received ci-BPC. Compared to baseline, documented prenatal breastfeeding counseling increased from 5 to 84% (<0.001), and inpatient counseling increased from 12 to 55% (p < 0.001). Breastfeeding initiation was similar (86 to 89%, p = 0.28), while exclusivity increased from 21 to 31% (p = 0.03). Any breastfeeding ≥6 weeks increased from 29 to 65% (p < 0.001) and was most improved for Black (32 to 50%, p < 0.01) and Latinx patients (37 to 71%, p < 0.01).

CONCLUSIONS

ci-BPC was associated with significant improvement in breastfeeding exclusivity and duration, and may address breastfeeding disparities.
