Breastfeeding Continuation Among Late Preterm Infants: Barriers, Facilitators, and Any Association With NICU Admission?

Challenges and Choices in Breastfeeding Healthy, Sick and Preterm Babies: Review

Although breastfeeding is associated with many health-related benefits for both mothers and children, the WHO recommendation for exclusive breastfeeding is not achieved by the majority in any WHO region. This paper aims to present the current state of research on challenges and choices in breastfeeding healthy, sick and preterm babies. The research was organized as a systematic search in PubMed and the study was performed as a narrative review after applying the PRISMA protocol. Finally, n = 57 studies were included. Both barriers and support factors emerge as a complex interaction of individual, group and societal factors, the precise understanding of which is relevant to increasing breastfeeding rates in the future. Knowledge as well as practical skills proved to be generally helpful, whereas the lack of breastfeeding support for mothers, who are often separated from their premature babies in hospital, was identified as a key risk factor for this subgroup. Appropriate training for healthcare professionals can improve the situation as a result. After discharge, workplace-related barriers are of major concern to allow further breastfeeding when maternity leave ends. Thus, the promotion of breastfeeding must be perceived as a task for society as a whole.

Distinguishing Between Lactation Failure and Breastfeeding Cessation: A Scoping Review

Background: Interchangeable terminology and definitions of breastfeeding difficulties may inadvertently influence premature cessation of breastfeeding. Lactation failure is a distinct concept from breastfeeding cessation, and it is vital to differentiate between them, especially in educating health care professionals in communicating and supporting mothers perinatally. Purpose: Comprehensively review varying terminology and definitions, providing a more nuanced understanding of lactation failure versus breastfeeding cessation, and highlighting physiological and social, emotional, mental, and commercial factors that influence breastfeeding outcomes. Method: A scoping review of published literature from medical and scientific databases such as MEDLINE (via PubMed), Scopus, and Web of Science from 2000 to 2023. Results: N = 476 publications were collected during the identification phase; N = 49 from 28 countries around the world met the inclusion criteria and were used in the review. Only N = 13 studies ventured definitions for the terms used. Factors affecting breastfeeding were categorized as physiological leading to lactation failure and distinguished from social, mental, emotional, or commercial factors leading to breastfeeding cessation. Recommendations and Conclusions: Understanding the complexity of the factors underlying lactation failure and breastfeeding cessation can be improved by delineating the terminology and definitions variations used to communicate, provide awareness, education, design and delivery of interventions and support for initiation, and continuation of breastfeeding. Further in-depth research and analysis of the complex issues and factors influencing breastfeeding practices is required.

Breastfeeding Barriers for Preterm Infants in Neonatal Intensive Care Unit Environments: A Systematic Assessment and Meta-Analysis

Background: Breast milk is vital for the growth and development of preterm infants. However, in Neonatal Intensive Care Units (NICUs), mothers often encounter significant challenges in breastfeeding. Objective: This study aims to systematically evaluate the barriers to breastfeeding in NICUs, thereby providing evidence-based support for clinical practices. Methods: A comprehensive search was conducted in the Cochrane Library, PubMed, Web of Science, Embase, and Scopus databases, up to September 2023. Meta-analysis was performed using Stata 15.0, applying fixed or random effects models to calculate odds ratios (OR) and their 95% confidence intervals (CI). Study quality was assessed using the Newcastle-Ottawa Scale for cases and cohorts and the Agency for Healthcare Research and Quality standards for cross-sectional studies. Heterogeneity was evaluated using Cochran's chi-squared test (Cochran's Q) and I2 statistics, and publication bias was assessed through funnel plots and symmetry tests. Results: A total of 32 studies were included, encompassing 96,053 preterm infants. The main barriers to breastfeeding in preterm infants included: low gestational age (OR = 1.36, 95% CI: 1.06-1.75), lower maternal education (OR = 1.64, 95% CI: 1.39-1.93), insufficient breast milk (OR = 2.09, 95% CI: 1.39-1.93), multiple births (OR = 1.615, 95% CI: 1.18-2.210), smoking (OR = 2.906, 95% CI: 2.239-3.771), and single motherhood (OR = 1.439, 95% CI: 1.251-1.654). Conclusion: This study underscores the need for individualized breastfeeding support strategies in NICUs, taking into account the diverse backgrounds of mothers. Future research should focus on unraveling the underlying mechanisms affecting breastfeeding in preterm infants, with the goal of enhancing breastfeeding rates and improving developmental outcomes.

Barriers to optimal breastfeeding of medically complex children in the UK paediatric setting: a mixed methods survey of healthcare professionals

BACKGROUND

Breastfeeding is indisputably significant for infants and children, as well as their mothers. However, when breastfed children are admitted to the paediatric ward, they may experience breastfeeding modification due to clinical challenges, lack of staff training and institutional barriers. Although previous research has identified multiple barriers to optimal feeding within the maternity, neonatal and community settings, we know less about the barriers that exist in paediatrics. Paediatric healthcare staff attitudes, training and awareness as well as ward culture are likely to have an impact on the experiences of families but are relatively unresearched in the paediatric setting, especially with regard to the multidisciplinary nature of clinical paediatric care. The aim of this study was to explore the attitudes, awareness and perceived barriers to effective breastfeeding support provision, as well as healthcare professional perception of barriers for families.

METHODS

This was a mixed methods study utilising a questionnaire which was completed by 409 healthcare professionals who identified as working within the paediatric setting. It included responses from paediatricians of all training grades, nurses, healthcare assistants and allied health professionals. Qualitative data from professionals were analysed to develop themes around professional and perceived parent barriers to optimal breastfeeding.

RESULTS

This study explored the barriers experienced by staff, as well as professionals' perception of parent barriers. These included lack of knowledge of how to help, a default formula culture, the pressure of maintaining strict fluid balance and breastfeeding being a low priority in the face of critical illness. Of the paediatric departments represented by this sample of healthcare professionals, most had a relatively poor culture of supporting breastfeeding, with multiple institutional barriers identified. Most professionals felt that there was not enough support for breastfeeding families on an average shift, and a large proportion identified as being one of just a few breastfeeding advocates on their ward.

CONCLUSION

In this relatively motivated and experienced sample of healthcare professionals, there were many identified barriers to optimal breastfeeding which could potentially be addressed by training that is carefully nuanced for the paediatric population. Ensuring that paediatric multidisciplinary healthcare professionals have sufficient skills and knowledge would address the identified challenge of poor awareness of breastfeeding and of how to overcome clinical lactation obstacles. Further improvements at policy level need to address the systemic lack of resourcing in paediatrics, as well as the lack of embedded breastfeeding-friendly organisational structures.

A quality improvement project to increase breast milk feeding of hospitalized late preterm infants in China

BACKGROUND

The breastfeeding rates of late preterm infants are lower than both term and extremely preterm infants. To explore the interventions of increasing full breast milk feeding rate of hospitalized late preterm infants on the 7th day after birth (D7) and evaluate the effect of these quality improvement (QI) interventions.

METHODS

The full breast milk feeding (amount of enteral breast milk reached 120ml/kg/d on D7) rate of hospitalized late preterm infants during May 2017 and November 2017 was set as the baseline before intervention, and the specific aim of promoting breast milk feeding was put forward. The Pareto Chart was used to analyze the factors that affect breast milk feeding process, as well as the discussion of multidisciplinary experts. Key drivers were constructed, including informational materials and education about breast milk feeding, consultations and support on optimal breast milk initiation, initiating breast milk expression within one hour after birth, accurate measurement and recording of expressed breast milk, stimulating continuous and effective lactation, proper breast pump selection in and out of hospital and sending and preserving of expressed milk to NICU. Control chart was used to monitor the monthly change of full breast milk feeding rate until the aim was achieved and sustained.

RESULTS

The baseline of full breast milk feeding rate of late preterm infants was 10%, and the aim of QI was to increase the rate to 60% within a two-year period. Control chart dynamically showed the full breast milk feeding rate increased to 80% with the implementation of the interventions, achieved and made the aim of QI sustained.

CONCLUSION

QI interventions including breast milk feeding education, early postpartum breast milk pumping, kangaroo care to stimulate breast milk secretion, and convenient way of transporting breast milk to NICU, could significantly improve the full breast milk feeding rate of hospitalized late preterm infants.

A Pilot Single-Site Randomized Control Trial: Investigating the Use of Donor Milk in the Late Preterm and Term Infant in the Neonatal Intensive Care Unit

Objective : We aimed to study the use of donor milk (DM) in term and late preterm infants (LPIs) when mother’s own milk (MOM) was unavailable. We hypothesized this study would be feasible and breastfeeding attempts and the percentage of MOM (MOM%) would increase with DM without adversely affecting growth. Study Design : This was a pilot study (n=32). Infants with gestational age >34 weeks admitted to the neonatal intensive care unit were included. Infants were randomized to: the human milk (MOM+DM) or formula (MOM+F) groups. Result : Consent rate was 52%. Breastfeeding attempts increased significantly over time in the MOM+DM group compared to the MOM+F group (group p=0.41, time p =0.02, group*time p=0.01) . Growth at multiple time points was similar when the two groups were compared. Conclusion : A study randomizing term infants and LPIs to DM or formula when MOM is unavailable is feasible. DM may increase breastfeeding attempts without compromising growth.

Factors Which May Contribute to the Success or Failure of the Use of Mother's Own Milk in a Level IV Neonatal Intensive Care Unit

BACKGROUND

Benefits of mother's own milk (MOM) for infants in neonatal intensive care units (NICUs) are well known. Many mothers provide for their infant's feedings during their entire hospitalization while others are unable. Knowledge is limited about which infant and maternal factors may contribute most to cessation of MOM feedings.

PURPOSE

Study aims were to (1) identify which maternal and infant risk factors or combination of factors are associated with cessation of provision of MOM during hospitalization, (2) develop a lactation risk tool to identify neonatal intensive care unit infants at higher risk of not receiving MOM during hospitalization, and (3) identify when infants stop receiving MOM during hospitalization.

METHODS

A data set of 797 infants admitted into a level IV neonatal intensive care unit before 7 days of age, whose mothers chose to provide MOM, was created from analysis of data from the Children's Hospital Neonatal Database. Maternal and infant factors of 701 dyads who received MOM at discharge were compared with 87 dyads who discontinued use of MOM by discharge using χ 2 , t tests, and Wilcoxon rank tests. Logistic regression was used to build a risk-scoring model.

RESULTS

The probability of cessation of MOM increased significantly with the number of maternal-infant risk factors. A Risk Calculator was developed to identify dyads at higher risk for cessation of MOM by discharge.

IMPLICATIONS FOR PRACTICE

Identifying mothers at risk for cessation of MOM can enable the healthcare team to provide optimal lactation management and outcomes.

IMPLICATIONS FOR RESEARCH

Although the Risk Calculator has potential to identify dyads at risk of early MOM cessation, further research is needed to validate these results.

The role of human milk feeds on inotrope use in newborn infants with sepsis

Background

Regarding neonatal hypotension, there is no certainty as to whether inotrope properties are beneficial or whether they may be harmful. However, given that the antioxidant content of human milk plays a compensatory role in neonatal sepsis and that human milk feeding has direct effects in modulating the cardiovascular function of sick neonates, this research hypothesized that human milk feeds might predict lower requirements of vasopressors in the management of neonatal septic shock.

Method

Between January 2002 and December 2017, all late preterm and full-term infants attending a neonatal intensive care unit, with clinical and laboratory findings of bacterial or viral sepsis, were identified in a retrospective study. During their first month of life, data on feeding type and early clinical characteristics were collected. A multivariable logistic regression model was constructed to determine the impact of human milk on the use of vasoactive drugs in septic newborns.

Results

322 newborn infants were eligible to participate in this analysis. Exclusively formula-fed infants were more likely to be delivered via C-section, to have a lower birth weight and a lower 1-minute Apgar score than their counterparts. Human milk-fed newborns had 77% (adjusted OR = 0.231; 95% CI: 0.07-0.75) lower odds of receiving vasopressors than exclusively formula-fed newborns.

Conclusion

We report that any human milk feeding is associated with a decrease in the need for vasoactive medications in sepsis-affected newborns. This observation encourages us to undertake further research to determine whether human milk feeds mitigate the use of vasopressors in neonates with sepsis.

Relationship Between Feeders and Exclusive Breastfeeding and Mixed Feeding During the First Month of Life

BACKGROUND

The critical time to continue or stop breastfeeding is during the first month after hospital discharge. Mothers receive lactation and physical support by fathers and others bottle-feeding human or formula milk to their infants.

PURPOSE

To describe the effect of feeders (mothers, fathers, and others) and different milk feeding on infants' weekly exclusive breastfeeding rates, from birth to 1 month after discharge.

METHODS

This study was a secondary analysis of a descriptive longitudinal study of mothers' (full-term: n = 77; late preterm: n = 39) breastfeeding experience, frequency of feeding, and infant feeding behaviors. Mothers completed a weekly questionnaire of who (mothers, fathers, and others) fed their infants human or formula milk by direct breastfeeding or bottle-feeding.

RESULTS

More than 60% of mothers reported fathers and others bottle-fed their infants. Exclusive breastfeeding rates were significantly higher when only mothers fed their infants at week 1 (P < .001), week 3 (P < .05), and week 4 (P < .05). Exclusive breastfeeding rates were negatively affected across time by bottle-feeding any human or formula milk for all feeders. When fathers bottle-fed their infants at week 1, the relative rates of exclusive breastfeeding at week 4 decreased to 52% (OR = 0.103; 95% CI, 0.26-0.404; P < .0001).

IMPLICATION FOR PRACTICE

Individuals providing early bottle-feeding adversely affect breastfeeding outcomes. Providers need to address maternal and paternal knowledge gaps about early breastfeeding practice.

IMPLICATIONS FOR RESEARCH

Further research is needed to explore clinical standard of care for management of infant weight loss, early supplementation, and support of exclusive breastfeeding outcomes.

The effect of a planned lactation education program on the mother's breastfeeding practice and weight gain in low birth weight infants: a randomized clinical trial study

Background

Low birth weight (LBW) infants are more prone to possible growth disorders, and their mothers need more specific education sessions regarding breastfeeding practice. This study aimed to investigate the effect of a planned lactation education program on the mother’s breastfeeding practice and weight gain in LBW infants.

Methods

A randomized clinical trial study was conducted on 80 mother-LBW infant dyads admitted to a gynecology and obstetrics hospital. The participants were selected randomly and divided into an experimental group and a control group, each with 40 mothers. Information on LBW infants’ weight and the mothers’ breastfeeding practice was collected using a questionnaire at birth. Then, a planned lactation education program was implemented in the experimental group in two sessions in the hospital and three 20-minute sessions in comprehensive health centers. Finally, the weight of 14–15 day-old and two-month-old LBW infants and the mothers’ breastfeeding practice for 14–15 day-old LBW infants in the two groups were recollected and analyzed using SPSS software version 16.

Results

Comparing the LBW infants’ weights and mothers’ breastfeeding practice revealed no statistically significant difference between the two groups pre-intervention. However, significant differences were observed between the two groups post-intervention in terms of weight gain in the LBW infants over 14–15 days and two months of age (F = 4720.6, p < 0.001) and the mothers’ breastfeeding practice for 14-15-day-old infants (p < 0.001).

Conclusions

Given the positive impact of lactation education on the mother’s breastfeeding practice and LBW infants’ weight, planned lactation education courses should be applied for LBW infants’ mothers.

The management of late preterm infants: effects of rooming-in assistance versus direct admission to neonatal care units

Late preterm infants (LPIs) represent a significant percentage of all neonates (6-8%), but there are limited published data on their postnatal management. Our aim was to compare the frequency of neonatal intensive care unit (NICU) admission and the breastfeeding rate of LPIs born at 35⁺⁰-36⁺⁶ weeks of gestation who were cared for by initial rooming in strategy rather than directly admitted to the special care unit (SCU) and, eventually, to the NICU. We carried out a retrospective study in the perinatal centers of Careggi University Hospital (CUH) and San Giovanni di Dio Hospital in Florence, Italy, where the first and second strategies were applied, respectively. Main outcomes were LPIs admission rate at SCU/NICU and breastfeeding rate at discharge. We studied 190 LPIs born at SGDH and 240 born at CUH. The admission rate in SCU (81 vs. 43%; P < 0.001) and NICU (20 vs. 10%; P = 0.008) was higher in SGDH than in CUH, as was the exclusive breastfeeding rate (36 vs. 22%; P < 0.001). However, infants who were assisted in rooming-in at CUH and infants with similar clinical characteristics at SGDH had similar mixed (60 vs. 69%) and exclusive (35 vs. 31%) breastfeeding rates.  Conclusion: Postnatal assistance of LPIs in rooming-in, eventually followed by admission in SCU/NICU based on their clinical conditions, allowed to safely halve their hospitalization. The assistance of infants in rooming-in did not negatively affect their breastfeeding rate. These results support the possibility of assisting LPIs in rooming-in. What is Known: • Late preterm infants represent a significant percentage of all neonates. • Early rooming-in and breastfeeding is recommended for late preterm infants. What is New: • Postnatal assistance of late preterm infants in rooming-in, followed when necessary by admission in neonatal units based on clinical conditions, allowed to safely avoid about half the number of hospitalizations in comparison with direct admission in neonatal units. • This strategy did not affect breastfeeding rate. Infants who were admitted to SCU/NICU after initial rooming-in had worst breastfeeding rate.

Barriers to optimal breast milk provision in the neonatal intensive care unit

OBJECTIVE

This study examines comprehensive patient and process factors that influence breast milk use in the NICU setting.

STUDY DESIGN

We examined the association of maternal, neonatal, and family factors and lactation support systems to identify gaps in breast milk use in a retrospective study of 865 infants born in 23-41 weeks gestation admitted to the NICU.

RESULTS

Breast milk at discharge for all infants was 89.3%, for extremely preterm 82.3%, moderately preterm 91.4%, late preterm 86.5%, and term 92.7%. Prematurity (OR 0.31 [0.17-0.56]), low birth weight, morbidities, Black maternal race (OR 0.20 [0.07-0.57]) and public insurance (OR 0.54 [0.34-0.85]) were associated with decreased breast milk use. Early initiation of feeds was associated with increased breast milk use.

CONCLUSIONS

There is a need to increase social as well as hospital support systems to address gaps in breast milk use in the NICU.

Barriers and Facilitators to Breastfeeding in Moderate and Late Preterm Infants: A Systematic Review

Rationale: Most of the preterm infants are born between 32 and 36 weeks of gestation (moderate to late preterm infants [MLPIs]). This comes with significant short- and long-term risks. Breastfeeding reduces many of these risks, but breastfeeding rates in MLPIs are lower than those in full-term infants. We performed a systematic review of studies identifying factors associated with successful breastfeeding in MLPIs and interventions to improve breastfeeding. Methods: Systematic search performed using PubMed April 24, 2020. In total, 11 articles describing barriers to breastfeeding in MLPIs and 6 articles about interventions to improve breastfeeding were included. Interventions were categorized according to different outcomes: breastfeeding initiation, continuation for 5 days to 6 weeks, and continuation ≥3 months. Because of heterogeneity in study characteristics, no meta-analysis was performed. Results: Breastfeeding rates were lower in those with lower socioeconomic status and single-parent households. Providing parents with more information and direct health care support significantly improved breastfeeding initiation. Cup feeding instead of bottle feeding had inconsistent effects on breastfeeding initiation and continuation. Continuous skin-to-skin contact did not affect breastfeeding initiation or continuation. Discussion: Risk groups for lower breastfeeding rates of MLPIs include mothers with lower socioeconomic status and single mothers. Interventions that may improve breastfeeding include cup feeding and providing parents with more information and health care support. Key limitations of included studies are lack of adequate adjustment for confounders and lack of blinding. However, this is the first systematic review identifying both risk groups and interventions to improve breastfeeding in MLPIs.

Duration of breastmilk feeding of NICU graduates who live with individuals who smoke

BACKGROUND

Breast milk has many benefits for infants, but initiating breastfeeding/pumping can be difficult for mothers of preterm infants, especially those who smoke (or live with individuals who smoke). The primary aim of this study was to identify risks for breastfeeding/pumping cessation with neonatal intensive care unit (NICU) infants' mothers who smoke or live with individuals who smoke, using a novel survival-analytic approach.

METHODS/DESIGN

Mothers (N = 360) were recruited for a secondhand smoke prevention intervention during infants' NICU hospitalizations and followed for ~6 months after infant discharge. Data were obtained from medical records and participant self-report/interviews.

RESULTS

The sample was predominantly ethnic/racial minorities; mean age was 26.8 (SD = 5.9) years. One-fifth never initiated breastfeeding/pumping (n = 67; 18.9%) and mean time-to-breastfeeding cessation was 48.1 days (SD = 57.2; median = 30.4 [interquartile range: 6.0-60.9]). Education, length of stay, employment, race/ethnicity, number of household members who smoke, and readiness-to-protect infants from tobacco smoke were significantly associated with breastfeeding cessation. Further, infants fed breast milk for ≥4 months had 42.7% more well-child visits (p < 0.001) and 50.0% fewer respiratory-related clinic visits (p < 0.05).

CONCLUSIONS

One-quarter of infants admitted to NICUs will be discharged to households where individuals who smoke live; we demonstrated that smoking-related factors were associated with mothers' breastfeeding practices. Infants who received breast milk longer had fewer respiratory-related visits.

IMPACT

One-quarter of NICU infants will be discharged to households where smokers live. Initiating/sustaining breastfeeding can be difficult for mothers of preterm NICU infants, especially mothers who smoke or live with others who smoke. Education, employment, race/ethnicity, length of stay, household member smoking, and readiness-to-protect infants from tobacco smoke were significantly associated with time-to-breastfeeding cessation. Infants fed breast milk for ≥4 months had 42.7% more well-child visits and 50.0% fewer respiratory-related clinic visits, compared to infants fed breast milk <4 months. Data support intervention refinements for mothers from smoking households and making NICU-based healthcare workers aware of risk factors for early breastfeeding cessation.

Improved exclusive breastfeeding rates in preterm infants after a neonatal nurse training program focusing on six breastfeeding-supportive clinical practices

BACKGROUND

Early breast milk expression, prolonged skin-to-skin contact, rooming-in, use of test-weighing and minimizing use of pacifiers are positively associated with exclusive breastfeeding of preterm infants, whereas use of nipple shields is negatively associated.

AIM

To test whether a training program for neonatal nurses with a focus on these six breastfeeding-supportive clinical practices affects the rate of preterm infants exclusively breastfed at discharge to home, the postmenstrual age at establishment of exclusive breastfeeding, and maternal self-reported use of the practice in the neonatal intensive care unit, the.

METHODS

A quasi-experimental multi-centre intervention study from 2016-2019 including a control group of 420 preterm mother-infant dyads, an intervention with a training program for neonatal nurses and implementation of weekly breastfeeding meetings for neonatal nurses, and an intervention group of 494 preterm mother-infant dyads.

RESULTS

Significantly more preterm infants in the intervention group were exclusively breastfed at discharge to home (66.6%) than in the control group (58.1%) p = 0.008. There was no significant difference in postmenstrual age at establishment of exclusive breastfeeding between control and intervention group (37.5 vs.37.8 weeks, p = 0.073). Compared to the control group the number of infants continuing daily skin-to-skin contact after incubator care increased (83.2% vs. 88.3%, p = 0.035), infants using a nipple shield decreased (61.8% vs. 54.2%, p = 0.029), and the number of mothers initiating breast milk expression before six hours post-partum increased (32.6% vs. 42.4%, p = 0.007). There was a significant correlation between percentage of neonatal nurses participating in the breastfeeding training program and changes in exclusive breastfeeding rates (Pearson Correlation 0.638, p = 0.047).

CONCLUSION

Exclusive breastfeeding rates in preterm infants and maternal self-reported use of breastfeeding-supportive practices increased by training neonatal nurses in the six clinical practices. It is important to include all nurses in the breastfeeding training program to ensure positive effect on exclusive breastfeeding rates.

Prematurity and breastfeeding initiation: A sibling analysis

AIM

Studies suggest breastfeeding initiation is less common for premature infants. This association may be confounded by socio-economic characteristics that correlate with the risk of premature birth. We compared premature and term-born children to determine whether prematurity independently predicted likelihood of breastfeeding continuation and duration.

METHODS

Data were obtained from women ages 15-44 years reporting at least two live pregnancies on the 2011-2017 National Survey of Family Growth. Participants completed a pregnancy and breastfeeding history. Breastfeeding initiation was defined as breastfeeding for at least 1 week, and duration of exclusive breastfeeding was recorded in months. Sibling fixed effects regression models were used to evaluate the impact of prematurity.

RESULTS

Among families with some children who were breastfed and others who were not (n = 2848 children), preterm birth was not associated with breastfeeding initiation (odds ratio = 1.11; P = .468). Among children who were ever breastfed, exclusive breastfeeding lasted 5% fewer months among children born preterm, compared with term-born siblings (incidence rate ratio = 0.95; P = .060).

CONCLUSION

Using sibling-group analysis to control for confounding, we found no independent association between prematurity and likelihood of breastfeeding initiation. This suggests interventions supporting breastfeeding for premature infants may need to address external barriers to breastfeeding not specifically preterm birth.

Maternal Body Mass Index and Breastfeeding Non-Initiation and Cessation: A Quantitative Review of the Literature

This study aims to investigate which maternal body mass index (BMI) categories are associated with the non-initiation or cessation of breastfeeding (BF) based on a quantitative review of the literature. We searched Ovid MEDLINE and EBSCO CINAHL for peer-reviewed articles published between 1946 (MEDLINE) or 1981 (CINAHL), and 2019. Selected studies were either cross-sectional or cohort studies, of healthy mothers and infants, that reported nutrition method (exclusive/full or any) and period (initiation/duration/cessation) of breastfeeding according to maternal BMI levels. Pairwise meta-analyses of 57 studies demonstrated that the pooled odds risks (OR) of not initiating BF among overweight and obese mothers compared to normal weight mothers were significant across 29 (OR 1.33, 95% confidence interval (CI), 1.15–1.54, I² = 98%) and 26 studies (OR 1.61, 95% CI, 1.33–1.95, I² = 99%), respectively; the pooled risks for BF cessation were inconsistent in overweight and obese mothers with substantial heterogeneity. However, we found that overweight mothers (n = 10, hazard ratio (HR) 1.16, 95% CI, 1.07–1.25; I² = 23%) and obese mothers (n = 7, HR 1.45, 95% CI: 1.27–1.65; I² = 44%) were both associated with an increased risk of not continuing any BF and exclusive BF, respectively. Overweight and obese mothers may be at increased risk of not initiating or the cessation of breastfeeding.

Mother And late Preterm Lactation Study (MAPLeS): a randomised controlled trial testing the use of a breastfeeding meditation by mothers of late preterm infants on maternal psychological state, breast milk composition and volume, and infant behaviour and growth

Background

Late preterm infants suffer from more complications and are less likely to be breastfed compared to term infants and their mothers experience higher levels of stress than mothers with term infants. The physiological or hormonal responses that influence milk ejection, milk production, and/or maternal behaviour are possible mechanisms by which maternal distress could negatively influence breastfeeding success. Maternal mood might also affect infant behaviour (feeding, sleeping, and crying) through changes in milk volume and composition, and consequently breastfeeding success and infant growth. Previous research, using relaxation therapy in 64 Malaysian first-time mothers breastfeeding their full-term infants, demonstrated that the therapy was effective in reducing maternal stress and improving infant growth. We hypothesise that expected benefits are even greater in a more vulnerable population where additional breastfeeding support is especially needed, such as in mothers of late preterm infants.

Methods/design

This protocol describes our randomised controlled trial that tests whether a breastfeeding meditation audio reduces maternal stress in mothers of late preterm infants in London. Home visits will be conducted at 2–3 and 6–8 weeks post-delivery. Participants will be randomised to a control group or an intervention group, where mothers will be asked to listen to a meditation tape on a daily basis while breastfeeding. The main outcomes of the intervention will be maternal stress markers and infant weight Z-score. Potential mediators will be the secondary outcomes and include breast milk macronutrient and hormone levels (ghrelin, leptin, cortisol, and adiponectin), milk volume assessed by 48-h test-weighing, and maternal engagement with the infant. Infant behaviour, including crying and sleeping, and infant appetite will be evaluated. Data about other mediators such as maternal perception of milk supply and salivary oxytocin will be collected.

Discussion

We hypothesise that the use of the breastfeeding meditation will reduce maternal stress and consequently improve infant growth mediated by changes in milk composition and volume and maternal behaviour. This study will allow us to understand the mother–infant factors that influence breastfeeding in late preterm infants and potentially identify a method that could improve mother, infant, and breastfeeding outcomes.

Breastfeeding progression in late preterm infants from birth to one month

This study aimed to describe and compare breastfeeding progression, infants' feeding behaviours, maternal feeding difficulties, and mothers' usage of breastfeeding interventions for singleton late preterm (LPT) and term infants. A further aim was to identify associated factors for exclusive breastfeeding at breast at 1 month in LPT infants. This was a cohort study where mothers of LPT infants from a neonatal unit (n = 60), LPT infants from a maternity unit (n = 62), and term infants from a maternity unit (n = 269) answered a questionnaire approximately 1 month after delivery. Findings showed no significant differences in exclusive breastfeeding at breasts between LPT infants admitted to the neonatal unit compared with the maternity unit, during the first week at home (38% vs. 48%), or at 1 month of age (52% vs. 50%). Term infants were more likely to be exclusively breastfed at the breast (86% and 74%, p < 0.05) compared with LPT infants. Multiple regression analysis showed that usage of a nipple shield, not feeding breast milk exclusively during the first week at home, or feeding less than 10 times per day at 1 month were statistically significant for not exclusively breastfeed at the breast. A protective factor was the mothers' experience of having an abundance of milk during the first week at home. In conclusion, LPT infants are less likely to be exclusively breastfed at the breast than term infants, highlighting the need for further research to guide interventions aimed at optimising exclusive breastfeeding rates.

Feeding the Late and Moderately Preterm Infant: A Position Paper of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition Committee on Nutrition

Nutritional guidelines and requirements for late or moderately preterm (LMPT) infants are notably absent, although they represent the largest population of preterm infants. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Committee on Nutrition (CoN) performed a review of the literature with the aim to provide guidance on how to feed infants born LMPT, and identify gaps in the literature and research priorities.Only limited data from controlled trials are available. Late preterm infants have unique, often unrecognized, vulnerabilities that predispose them to high rates of nutritionally related morbidity and hospital readmissions. They frequently have feeding difficulties that delay hospital discharge, and poorer rates of breastfeeding initiation and duration compared with term infants. This review also identified that moderately preterm infants frequently exhibit postnatal growth restriction.The ESPGHAN CoN strongly endorses breast milk as the preferred method of feeding LMPT infants and also emphasizes that mothers of LMPT infants should receive qualified, extended lactation support, and frequent follow-up. Individualized feeding plans should be promoted. Hospital discharge should be delayed until LMPT infants have a safe discharge plan that takes into account local situation and resources.In the LMPT population, the need for active nutritional support increases with lower gestational ages. There may be a role for enhanced nutritional support including the use of human milk fortifier, enriched formula, parenteral nutrition, and/or additional supplements, depending on factors, such as gestational age, birth weight, and significant comorbidities. Further research is needed to assess the benefits (improved nutrient intakes) versus risks (interruption of breast-feeding) of providing nutrient-enrichment to the LMPT infant.

Do a Few Weeks Matter? Late Preterm Infants and Breastfeeding Issues

The late preterm infant population is increasing globally. Many studies show that late preterm infants are at risk of experiencing challenges common to premature babies, with breastfeeding issues being one of the most common. In this study, we investigated factors and variables that could interfere with breastfeeding initiation and duration in this population. We conducted a prospective observational study, in which we administered questionnaires on breastfeeding variables and habits to mothers of late preterm infants who were delivered in the well-baby nursery of our hospital and followed up for three months after delivery. We enrolled 149 mothers and 189 neonates, including 40 pairs of twins. Our findings showed that late preterm infants had a low rate of breastfeeding initiation and early breastfeeding discontinuation at 15, 40 and 90 days of life. The mothers with higher educational levels and previous positive breastfeeding experience had a longer breastfeeding duration. The negative factors for breastfeeding were the following: Advanced maternal age, Italian ethnicity, the feeling of reduced milk supply and having twins. This study underlines the importance of considering these variables in the promotion and protection of breastfeeding in this vulnerable population, thus offering mothers tailored support.

Oral Sensorimotor Intervention Enhances Breastfeeding Establishment in Preterm Infants

OBJECTIVE

To assess the efficacy of an oral sensorimotor intervention on breastfeeding establishment and maintenance in preterm infants.

STUDY DESIGN

Thirty-one preterm infants born ≤34 weeks gestation were randomized into an experimental or control group. The experimental group received a 15-minute program consisting of stroking the peri-oral structures for the first 5 minutes, tongue exercises for the next 5 minutes, followed by non-nutritive sucking for the final 5 minutes. The control group received a sham intervention for the same duration. The interventions were administered once daily for 10 days. The outcomes included: time to attainment of full oral feeding, breastfeeding acquisition (i.e., ≥50% of direct breastfeeding at hospital discharge), breastfeeding skill assessment using the Preterm Infant Breastfeeding Behavior Scale (PIBBS), length of hospitalization, and breastfeeding maintenance at 3 and 6 months posthospitalization.

RESULTS

Full oral feeding was attained earlier in the experimental group compared with the control (10.7 ± 2.1 vs. 19.3 ± 3.6 days, p < 0.01). This was associated with a greater number of infants in the intervention group acquiring breastfeeding at hospital discharge compared with the controls (n = 11 vs. 5, p = 0.049). There was no statistical difference in PIBBS score, length of hospitalization, and breastfeeding rates at 3 and 6 months posthospitalization between the two groups (all tests, p > 0.32).

CONCLUSIONS

An oral sensorimotor intervention accelerated the achievement of full oral feeding and enhanced direct breastfeeding rates at hospital discharge only. Provision of an oral sensorimotor intervention is a safe and low-cost intervention that may increase breastfeeding rates in a highly vulnerable population.

Factors associated with delayed initiation of breastfeeding: a cross-sectional study in South Sudan

Background

The global breastfeeding recommendation states that all infants should be put to the breast within one hour of birth, which is defined as timely initiation or early initiation of breastfeeding. Early initiation of breastfeeding is associated with reduced risk in infant illness and death. Understanding the determinants of delay in initiation of breastfeeding might spur health staff and policy makers to foster timely breastfeeding. We assessed the prevalence and determinants of delay in initiation of breastfeeding among mothers in Juba Teaching Hospital.

Methods

The present study enrolled 806 mother-infant pairs within 24 hrs of birth in Juba Teaching Hospital in 2017. The mothers were interviewed about the time of initiation of breastfeeding, sociodemographic and birth characteristics. The independent variables associated with delay in initiation of breastfeeding were identified using multivariable logistic regression analysis.

Results

In the current study, 52% (418/806) of the mothers initiated breastfeeding later than one hour after birth. Birth by Caesarean section (Adjusted Odds Ratio [AOR] 41; 95% Confidence Interval [CI] 12.21, 138), discarding of colostrum (AOR 9.89; 95% CI 4.14, 23.62), unmarried mothers (AOR 3.76; 95% CI 1.53, 9.24), exposure to infant formula advertisement (AOR 1.82; 95% CI 1.09, 3.02) and no house ownership (AOR 1.52; 95% CI 1.11, 2.09) were independent factors associated with delay in initiation of breastfeeding.

Conclusion

We found that more than half of the mothers delayed the initiation of breastfeeding. Therefore, we recommend training on best breastfeeding practices and counselling skills for health staff in Juba Teaching Hospital. Policy dialogue, with the relevant ministries and departments on the promotion and protection of early initiation of breastfeeding is crucial.

Outcomes Associated With Type of Milk Supplementation Among Late Preterm Infants

OBJECTIVE

To assess whether type of milk supplementation provided to breastfeeding late preterm infants was associated with hospital length of stay (LOS) or breastfeeding status at discharge.

DESIGN

Retrospective chart review.

SETTING

Tertiary care teaching hospital in the southern United States.

PARTICIPANTS

Late preterm infants 35 0/7 to 36 6/7 weeks gestational age (N = 183) admitted to the mother-baby unit between November 1, 2014, and October 31, 2016.

METHODS

The exposure of interest was type of milk supplementation, for example, expressed human milk, pasteurized donor human milk, and formula. Outcomes measured were LOS and breastfeeding status at discharge. Generalized Poisson regression models were used to compare LOS by type of milk supplementation. Modified Poisson regression models were used to estimate risk ratios and 95% confidence intervals for associations with breastfeeding status at discharge.

RESULTS

The LOS for breastfed infants supplemented with expressed human milk and/or pasteurized donor human milk did not differ significantly from exclusively breastfed infants who received no supplement. Exclusively formula-fed infants had longer LOS of 3.2 days compared with 2.6 days for exclusively breastfed infants (p = .001). Breastfed infants who received any formula supplementation were 16% less likely to continue breastfeeding until day of discharge compared with breastfed infants who received human milk supplementation (risk ratio = .84, 95% confidence interval [.77, .92]).

CONCLUSION

The high prevalence of supplementation among breastfeeding late preterm infants underscores the potential effect of type of milk supplementation on LOS and breastfeeding outcomes. Our findings suggest that human milk supplementation discourages transition to formula feeding before hospital discharge without increasing LOS.

Human milk peptides differentiate between the preterm and term infant and across varying lactational stages

Variations in endogenous peptide profiles, functionality, and the enzymes responsible for the formation of these peptides in human milk are understudied. Additionally, there is a lack of knowledge regarding peptides in donor human milk, which is used to feed preterm infants when mother's own milk is not (sufficiently) available. To assess this, 29 human milk samples from the Dutch Human Milk Bank were analyzed as three groups, preterm late lactation stage (LS) (n = 12), term early (n = 8) and term late LS (n = 9). Gestational age (GA) groups were defined as preterm (24-36 weeks) and term (≥37 weeks). LS was determined as days postpartum as early (16-36 days) or late (55-88 days). Peptides, analyzed by LC-MS/MS, and parent proteins (proteins from matched peptide sequences) were identified and quantified, after which peptide functionality and the enzymes responsible for protein cleavage were determined. A total of 16 different parent proteins were identified from human milk, with no differences by GA or LS. We identified 1104 endogenous peptides, of which, the majority were from the parent proteins β-casein, polymeric immunoglobulin receptor, α_s1-casein, osteopontin, and κ-casein. The absolute number of peptides differed by GA and LS with 30 and 41 differing sequences respectively (p < 0.05) Odds likelihood tests determined that 32 peptides had a predicted bioactive functionality, with no significant differences between groups. Enzyme prediction analysis showed that plasmin/trypsin enzymes most likely cleaved the identified human milk peptides. These results explain some of the variation in endogenous peptides in human milk, leading to future targets that may be studied for functionality.

Adherence to Safe Sleep Recommendations by Families With Higher-order Multiples

BACKGROUND

More than 95% of higher-order multiples are born preterm and more than 90% are low birth weight, making this group of infants especially vulnerable to sudden infant death syndrome (SIDS). Emerging evidence suggests that families with twins face challenges adhering to the American Academy of Pediatrics (AAP) recommendations to reduce SIDS risks. Adherence to the AAP recommendations in families with higher-order multiples has not been described.

PURPOSE

This study describes SIDS risk reduction infant care practices for higher-order multiples during the first year of life.

METHODS

Mothers caring for higher-order multiple-birth infants were recruited from an online support group. An online survey was used to assess infant care practices when the infants were first brought home from the hospital as well as at the time of the survey.

RESULTS

Ten mothers of triplets and 4 mothers of quadruplets responded. Less than 80% of the mothers practiced "back to sleep" immediately postdischarge. Supine sleep positioning decreased over time, particularly during daytime naps. Only 50% of the infants shared the parents' bedroom and approximately 30% bed-shared with their siblings. Sleep-time pacifier use was low.

IMPLICATIONS FOR PRACTICE

Safe sleep education must include specific questions regarding home sleeping arrangements, encouragement of breast milk feedings, supine positioning, and pacifier use at every sleep for higher-order multiple infants well before discharge in order for parents to plan a safe sleep environment at home.

IMPLICATIONS FOR RESEARCH

Prospective studies to identify barriers and facilitators can inform future strategies supporting adherence to safe sleep practices for higher-order multiple infants.
