Recommendations to avoid breastfeeding for women living with HIV in high income countries has resulted in a gap in the literature on how healthcare professionals can provide the highest standard of lactation counseling.

(1) Describe social and emotional experiences of infant feeding for women living with HIV in high income countries; (2) raise ethical considerations surrounding the clinical recommendation in high income countries to avoid breastfeeding.

A systematic literature search was conducted between January 1, 2008 and June 20, 2019. A total of 900 papers were screened and six met the inclusion criteria: (a) the sample was drawn from a high-income country regardless of the nativity of participants; (b) some or all participants were women living with HIV. Metasynthesis, according to Noblit and Hare (1988), was used to synthesize the experiences of women living with HIV in high-income countries and their experiences in infant feeding decisions.

Participants in this sample suffered a substantial emotional burden associated with infant feeding experiences potentially leading to risk of internalized stigma, suggesting that infant feeding considerations may contribute to HIV stigma in unique ways. Four overarching themes were identified expressing the meaning of avoidance of breastfeeding: maternal self-worth, deculturalization, surveillance, and intersectionality.

Women in high-income countries living with HIV deserve the highest standard of lactation care and counseling available. Healthcare professionals in high-income countries are ethically obligated to provide evidenced-based lactation care and counseling to women living with HIV.

Although breastfeeding is a major public health priority and provides numerous benefits, women veterans encounter many barriers to initiating and sustaining breastfeeding. Women veterans are a growing population with unique health care needs related to exposures and injuries experienced during military service. These military experiences are linked to health diagnoses known to impact postpartum health behaviors, such as breastfeeding.

The aim of this study was to identify factors associated with breastfeeding at 4 weeks postpartum among women veterans.

We used 2016-to-2018 survey data from women veterans (N = 420), interviewed before and after delivery, who were enrolled in maternity care coordination at a national sample of Veterans Health Administration facilities. Using the social ecological model, logistic regression was employed to explore the relationship between breastfeeding at least 4 weeks and postpartum and maternal/infant characteristics, interpersonal dynamics, community influences, and system factors.

The rate of breastfeeding at 4 weeks postpartum was 78.6% among this sample of veterans. Self-employed participants were 2.8 times more likely to breastfeed than those who were employed outside the home. Participants who had been deployed at any point in their military career were twice as likely to breastfeed compared with those who never deployed. In this study sample, race independently predicted lower rates of breastfeeding, with African American participants being 48% less likely to breastfeed as compared with white participants.

Our analysis suggests significant racial disparities in breastfeeding within veteran populations utilizing Veterans Health Administration, despite access to multiple sources of support from both the Veterans Health Administration and the community.

Donor human milk supplementation for healthy newborns has increased. Racial-ethnic disparities in supplementation have been described in the neonatal intensive care unit but not in the well newborn setting.

The aim of this study was to identify maternal characteristics associated with donor human milk versus formula supplementation in the well newborn unit.

This retrospective cohort study includes dyads of well newborns and their mothers (N = 678) who breastfed and supplemented with formula (n = 372) or donor human milk (n = 306) during the birth hospitalization at a single hospital in the midwestern United States. Maternal characteristics and infant feeding type were extracted from medical records. Chi-square and logistic regression were used to examine associations between maternal characteristics and feeding type.

Nonwhite women were less likely to use donor human milk. Compared to non-Hispanic white women, the largest disparity was with Hispanic (adjusted odds ratio [OR] = 0.28, 95% CI [0.12, 0.65]), then non-Hispanic black (adjusted OR = 0.32, 95% CI [0.13, 0.76]) and Asian women (adjusted OR = 0.34, 95% CI [0.16, 0.74]). Lower donor human milk use was associated with primary language other than English and public versus private insurance.

The goal of improving public health through breastfeeding promotion may be inhibited without targeting donor human milk programs to these groups. Identifying the drivers of these disparities is necessary to inform person-centered interventions that address the needs of women with diverse backgrounds.

Use of pasteurized donor milk is recommended in many situations when own mother’s milk is not available. One existing knowledge gap is access to donor milk for infants in government custody (foster care).

The focus of this case study is an infant born at 41 weeks who was discharged from the hospital into foster care. The infant soon developed failure to thrive due to formula intolerance.

After trying multiple formulas, which included elemental formulas, and hospitalization, the infant began pasteurized donor milk. Within 24 hr, the infant began gaining weight. Medicaid denied two authorization requests for payment, and the state’s Department of Human Services ultimately agreed to cover the discounted donor milk fees until the infant reached 1 year of age.

This foster child suffered through months of failure to thrive and hospitalization before receiving human milk feedings. This care violated ethical principles of beneficence, autonomy, and justice. State officials should review their policies and regulations for providing human milk to children in their care and facilitate access to that milk when needed.

Prenatal care providers play a central role in breastfeeding outcomes. A survey on obstetricians’ support of breastfeeding was conducted in 1993 in Monroe County, NY. Since the landscape of prenatal care and breastfeeding support has changed significantly in the past 2 decades, we repeated and extended this survey in 2015.

To determine changes in breastfeeding support by prenatal care providers over a 20 year period.

We sent a 46-item on-line or paper questionnaire to all categories of prenatal care providers identified by an online search. A breastfeeding support score was created based on the prior survey, with a maximum score of 3. One point was awarded for: (1) personally discussing breastfeeding; (2) generally suggesting breastfeeding; and (3) commonly receiving questions from patients. Data were analyzed using Chi-square.

We had 164 participants (response rate 80%). More current participants, compared to 1993, reported discussing (97% vs. 86%, p < .001) and recommending (93% vs. 80%, p = .001) breastfeeding. Only 10% of 2015 participants gave infant formula samples, compared with 34% in 1993 (p < .0001). Improvement in the support score was seen, with 98% of current participants having high scores compared to 87% in 1993 (p < .001). Similar numbers reported receiving breastfeeding education, though more reported that the education was inadequate (54% vs. 19%, p < .0001).

Breastfeeding support improved significantly over time, even though breastfeeding education has not improved in quality or quantity. Improving education of prenatal care providers may help future providers be more prepared to support breastfeeding.

Breastfeeding offers benefits to mother and child but is frequently not practiced among women whose pregnancy is complicated by gestational diabetes mellitus. Factors associated with not initiating or not maintaining breastfeeding among these women have been little investigated.

(1) To evaluate the frequency of breastfeeding for 30 days among women with a recent pregnancy complicated by gestational diabetes and (2) to determine factors associated with not initiating or not maintaining breastfeeding.

Between January 2014 and July 2017 we enrolled women with gestational diabetes at high-risk prenatal services in three Brazilian cities. We collected baseline sociodemographic and health data and followed up with participants by telephone. Using Kaplan–Meier curves, we calculated the proportions of participants not initiating breastfeeding or not maintaining it for at least 30 days. We used Poisson regression with robust variance to identify factors related to this outcome.

Of the 2328 participants with complete information, 2236 (96.1%) initiated breastfeeding, and 2166 (93.1%) maintained breastfeeding for 30 days. Not having breastfed the previous infant (relative risk [RR] = 5.02, 95% CI [3.39, 7.45]), smoking during pregnancy (RR = 2.37, 95% CI [1.48, 3.80]), infant with health problems (RR = 2.25, 95% CI [1.27, 3.99]), early preterm birth (RR = 2.49, 95% CI [1.07, 5.77]), and not intending to breastfeed (RR = 3.73, 95% CI [1.89, 7.33]) were related to not maintaining breastfeeding for at least 30 days.

Breastfeeding initiation was nearly universal among participants, and most maintained breastfeeding for 30 days. Factors relating to not breastfeeding at 30 days were easily identifiable.

Maternal milk production requires the neuropeptide oxytocin. Individual variation in oxytocin function is a compelling target for understanding low milk production, a leading cause of breastfeeding attrition. Complicating the understanding of oxytocin pathways is that vasopressin may interact with oxytocin receptors, yet little is known about the role of vasopressin in lactation.

The aims of this study were (1) to describe maternal plasma oxytocin, vasopressin, and prolactin patterns during breastfeeding following low-risk spontaneous labor and birth in healthy first-time mothers and (2) to relate hormone patterns to maternal characteristics and breastfeeding measures.

Eligible women were recruited before hospital discharge. Forty-six participants enrolled and 35 attended the study visit. Participants kept a journal of breastfeeding frequency, symptoms of lactogenesis, and infant weight. Plasma samples were obtained at breastfeeding onset on Day 4–5 postpartum, and repeated after 20 min. Hormones were measured with immunoassays. Infant weight change, milk transfer, and onset of lactogenesis were also measured.

Baseline oxytocin and vasopressin were inversely related to one another. Oxytocin and prolactin increased significantly across the 20-min sampling period while vasopressin decreased. Higher oxytocin was associated with higher maternal age, lower BMI, shorter active labor, physiologic labor progression, and less weight loss in the newborn. Higher vasopressin correlated with younger maternal age, higher BMI, and greater newborn weight loss.

Oxytocin and vasopressin have contrasting relationships with maternal clinical characteristics and newborn weight gain in early breastfeeding infants. Further study is needed to understand how oxytocin and vasopressin influence lactation outcomes.

Low milk supply is frequently reported as a reason for exclusive breastfeeding cessation.

To determine the occurrence of, and the risk factors associated with, delayed onset of lactogenesis II among primiparas seen at a Baby-Friendly Hospital in Brazil.

We conducted a prospective longitudinal observational cohort study of 224 primiparas who had a singleton delivery. Data were first collected at the hospital. We assessed the onset of lactogenesis on day four postpartum, based on maternal reports of changes in breast fullness. Breastfeeding practices and Edinburgh Postnatal Depression Scale were evaluated on day seven postpartum. Using Poisson regression, we assessed significant factors associated with delayed onset of lactogenesis II.

Delayed lactogenesis II occurred in 18.8% (n = 42) of participants and was significantly associated with alcohol drinking during pregnancy (IRR = 2.710, 95% CI [1.469, 4.996]); Edinburgh Postnatal Depression Scale scores ≥ 10 (IRR = 2.092, 95% CI [1.118, 3.916]), and the age of the mother (IRR: 1.081, 95% CI [1.039, 1.125]).

Postpartum depression and alcohol ingestion during pregnancy may be associated with lactogenesis II delay, but more research is needed to elucidate the directionality of these relationships. Older mothers are at risk of delayed lactogenesis II onset. The frequency of delayed lactogenesis in this population is similar to the rates seen in previous Latin America studies and much lower than the ranges seen in North America, possibly because of the low proportion of obesity and severe gestational diabetes in this sample.

Few studies have examined the role of maternal emotions in breastfeeding outcomes.

We aimed to determine the extent to which positive maternal emotions during human milk feeding at 2 months were associated with time to any and exclusive human milk feeding cessation and overall breastfeeding experience.

A sample of 192 women intending to breastfeed for at least 2 months was followed from the third trimester until 12 months postpartum. Positive emotions during infant feeding at 2 months were measured using the modified Differential Emotions Scale. Cox proportional hazards regression was used to estimate adjusted hazard ratios (aHR) for time to any and exclusive human milk feeding cessation associated with a 1-point increase in positive emotions. Linear regression was used to estimate the association between positive emotions and maternal breastfeeding experience reported at 12 months.

Among those human milk feeding at 2 months, positive emotions during feeding were not associated with human milk feeding cessation by 12 months (aHR = 0.94, 95% CI [0.64, 1.31]). However, among women exclusively human milk feeding at 2 months, a 1-point increase in positive emotions was associated with a 35% lower hazard of introducing formula or solid foods by 6 months (aHR = 0.65, 95% CI [0.46, 0.92]). Positive emotions were associated with a significantly more favorable maternal report of breastfeeding experience at 12 months. Results were similar in sensitivity analyses using maternal feelings about breastfeeding in the first week as the exposure.

A positive maternal emotional experience of feeding is associated with breastfeeding outcomes.

When an exclusively breastfed infant develops hematochezia, the pediatrician may recommend elimination of dairy and soy products from a mother’s diet, but there is limited scientific evidence to indicate that altering the maternal diet will lead to resolution of the problem.

To estimate the likelihood that maternal dairy and soy avoidance will resolve rectal bleeding in an exclusively breastfed infant.

This was a prospective, longitudinal, one-group pre/post study involving mothers of exclusively breastfed infants at least 2 weeks but less than 6 months of age with a positive stool guaiac test in the absence of an intestinal lesion or other explanation for the blood. Participants agreed to follow a dairy and soy elimination/rechallenge protocol, maintain a food diary, and have their infant re-tested at 3-week intervals to determine the outcome of the dietary changes. One participant was lost to follow-up, leaving a final sample size of N = 19.

All infants continued to test positive for blood in the stool after their mothers eliminated foods containing dairy or soy. Therefore, 0% (0/19) of infants responded to their mother’s restricted diet, 95% confidence interval (one-sided [0%, 15%]).

Given these results, we must call into question the rationale for advising breastfeeding mothers to eliminate dairy and soy from their diet in response to their infant’s unexplained rectal bleeding.

Although the Baby-Friendly Hospital Initiative has improved breastfeeding rates globally, weak monitoring still affects hospital-level implementation.

To reassess compliance of a Baby-Friendly Hospital with the Ten Steps to Successful Breastfeeding, International Code of Marketing of Breast-milk Substitutes, HIV and Infant Feeding, and Mother-Friendly Care following the WHO/UNICEF global criteria.

In this cross-sectional, prospective, mixed-methods study (N = 180), clinical staff (n = 60), pregnant women (n = 40), postpartum mothers (n = 60), and mothers of babies in intensive care (n = 20) were randomly selected from one urban secondary-level public hospital in Ghana designated as Baby-Friendly in 2004 but never reassessed. Data were collected through interviews, document reviews, and observations using the revised WHO/UNICEF external reassessment tool and analyzed quantitatively using the Baby-Friendly Hospital Initiative computer tool. Scores higher than 80% signified a pass (high compliance). Scores rated as low (< 50%) and moderate (50–80%) signified noncompliance.

The facility passed the criteria for full compliance with the International Code (86%) but failed other components. Compliance with the Ten Steps was moderate (55%). Step 7 about rooming-in (84%) and Step 9 about human milk substitutes (100%) were passed, whereas Step 1 about written breastfeeding policies (0%), Step 2 about staff training (7%), and Step 4 about early breastfeeding initiation (31%) were met the least. Compliance with Mother-Friendly Care (34%) and HIV and Infant Feeding (47%) were low. Main implementation gaps were unavailability of policies and staff’s inadequate knowledge about Baby-Friendly practices.

Improving staff training and maternal counseling, routinely reassessing designated facilities, and providing technical support in problematic areas might sustain implementation.
