Breastfeeding progression in late preterm infants from birth to one month

Direct breastfeeding frequency of late preterm and term infants in the neonatal intensive care unit and availability of mother's own milk at six months of age. a retrospective cohort study

BACKGROUND

Mother's Own Milk (MOM) reduces the risk of complications in premature infants. Breastfeeding rates for late preterm and term infants in the neonatal intensive care unit (NICU) are significantly lower than that of breastfed healthy term newborns at 6 months of age.

DESIGN

This was a retrospective cohort study of neonates born at 34 weeks 0 days or later. Infants who were directly breastfed in the NICU and were discharged on breast milk were included. Logistic regression modeling was used to determine the significance of association.

RESULTS

171 mother-infant dyads were included. After adjusting for confounders, the number of breastfeeding attempts during the NICU stay was significantly associated with the availability of MOM at six months of age (p = 0.003, 95% CI 1.02 to 1.14).

CONCLUSION

This study is the first to show an association between the number of direct breastfeeding attempts in the NICU and availability of MOM at six months of age.

Maternal Reasons for Early Termination of Exclusive Breastfeeding in Premature Infants: A Prospective Study

PURPOSE

Maternal concerns for health and growth in prematurely born infants affect the breastfeeding duration.

METHOD

This prospective observational study evaluated whether maternal concerns regarding insufficient milk supply were supported by inadequate nutrients in human milk or low infant growth. The study followed mothers of 211 premature born infants for 6 months after delivery.

RESULTS

Of the 211 infants, 156 were not exclusively breastfed for the recommended 6 months after delivery. For 79 of these 156 infants, termination was due to maternal concerns regarding insufficient milk supply. There was no difference in human milk nutrients or infant growth when comparing infants who were exclusively breastfed with those who were not.

CONCLUSION

Maternal concern regarding insufficient milk supply was the primary explanation for termination of exclusive breastfeeding after premature delivery. Concerns regarding insufficient milk supply were not found associated with inadequate nutrients in the human milk, nor with low infant growth.

IMPLICATIONS

Breastfeeding support should remain in focus in this population.

Efficacy of a breastfeeding support education program for nurses and midwives: a randomized controlled trial

BACKGROUND

Nutritional support influences the growth and development of late preterm infants (LPIs) and their long-term health status. However, healthy LPIs have a shorter hospital stay and may not receive adequate care after discharge. In this study, we developed and evaluated the effectiveness of an educational program for nurses and midwives to enable them to support breastfeeding of healthy LPIs.

METHODS

A randomized controlled trial was conducted in Japan from July 2018 to April 2019. The participant pool consisted of nurses and midwives working at midwiferies and obstetric centers in Tokyo, Japan. A total of 395 candidates were recruited for participation across 79 facilities. The final participants were assigned to two groups: the breastfeeding support for LPIs program (BSLPI group; n = 36) or the non-technical skills program (NTS group; n = 33). The measures included the Self-Efficacy of Breastfeeding Support scale (SBS), the Social Skills in Nursing Interactions with Mothers (SS) scale, and the Knowledge and Skills Necessary for Breastfeeding Support for LPIs test (K-S). Scores for each measure were collected before, after, and one-month after the intervention. Repeated-measures ANOVA was used to identify differences (main effects) according to program (BSLPI and NTS) and time (before, immediately after, and one month after intervention).

RESULTS

All 69 participants attended the program. Main effects of the program were observed only for K-S scores (F[1,58] = 78.57, p = 0.01). No significant differences were found for SBS (F[1,58] = 0.63, p = 0.43) or SS scores (F[1,58] = 1.51, p = 0.23).

CONCLUSIONS

Participation in the BSLPI was related to improved breastfeeding support knowledge and skills but was not related to improvements in nurses' self-efficacy or social skills.

Human Milk Sodium and Potassium as Markers of Mastitis in Mothers of Preterm Infants

Introduction: This prospective longitudinal study examined changes in milk sodium concentration (Na) and sodium:potassium ratio (Na:K), microbiological culture, milk production, and breast health in relation to mastitis after preterm birth. Methods: We studied women who gave birth at 29-34 weeks of gestation in a tertiary obstetric hospital in Perth, Western Australia. Milk samples, 24-hour milk production, and breast health data were collected every second day to day 10 postpartum, then every third day until infant discharge from the neonatal unit. Milk Na and K were measured at point of care (POC) using handheld ion selective meters, and Na:K calculated. Cultures were performed on postnatal days 8, 13, and every 6 days thereafter. For episodes of mastitis, milk was cultured at onset, and Na and Na:K measured daily until resolution. Women were followed up at 4 and 8 weeks postpartum. Results: In a sample of 44 women, 4 mastitis cases were detected in 3 women during their infants' neonatal stay; all had elevated milk Na and Na:K that resolved within 48 hours; 2/4 experienced reduced milk production and 1/4 had heavy growth of Staphylococcus epidermidis. A further 2 mastitis cases were reported in 39 women followed up to 8 weeks postpartum. Four women had elevated milk Na and Na:K without clinical signs of mastitis; three also had reduced milk production. Conclusions: POC testing of milk Na and/or Na:K may offer a useful indicator of breast health. Mastitis may cause an acute reduction in milk production regardless of the presence of culture-positive infection.

Longitudinal Follow-up of Preterm Breastfeeding to 12 Weeks Corrected Gestational Age

BACKGROUND

Preterm infants have shorter breastfeeding duration than that of term infants. Details of postdischarge feeding methods and difficulties are needed to inform the care of preterm breastfeeding dyads.

PURPOSE

To describe postdischarge breastfeeding characteristics of mother-preterm infant dyads up to 12 weeks corrected gestational age (CGA).

METHODS

A prospective observational study of preterm dyads (birth 24-33 weeks' gestation) that fed their mother's own milk (MOM) at discharge from a neonatal unit in Perth, Western Australia. Feeding method and frequency, breastfeeding duration, difficulties, and nipple shield use were recorded at 2, 6, and 12 weeks CGA.

RESULTS

Data were obtained for 49 mothers (singleton infant n = 39, twins n = 10). At 12 weeks CGA, 59% fed any MOM with 47% exclusively fed MOM and 31% fully breastfed. Nipple shield use reduced from 42% at 2 weeks CGA to 11% at 12 weeks CGA. Compared with mothers who exclusively fed MOM at discharge (n = 41) those who fed both MOM and infant formula (n = 8) were more likely to wean before 12 weeks CGA ( P < .001). Weaning occurred before 2 weeks CGA in 12/19 (63%), with low milk supply the most frequently cited reason.

IMPLICATIONS FOR PRACTICE

Most mothers with a full milk supply at discharge successfully transition to predominant breastfeeding. Frequent milk removal needs to be prioritized throughout the preterm infant's hospital stay.

IMPLICATIONS FOR RESEARCH

Examination of facilitators and barriers to early and continued frequent milk removal across the postpartum period is required to identify strategies to optimize lactation after preterm birth.

Early infancy growth, body composition and type of feeding in late and moderate preterms

BACKGROUND

Late and moderate preterm (LMPT) infants are at risk for adverse later life outcomes. We determined the association between feeding method at enrolment and growth and body composition of LMPT infants until 3 months corrected age (3mCA).

METHODS

Infants born between 32⁺⁰ and 36⁺⁶ weeks of gestation (n = 107) were enrolled up to 4 weeks corrected age and stratified according to feeding at enrolment. We performed anthropometric measurements at enrolment, term equivalent age (TEA) and 3mCA, including skinfold measurements and body composition using dual X-ray absorptiometry (DEXA).

RESULTS

Feeding method at enrolment was associated with fat mass (FM) (breast 554.9 g, mixed 716.8 g, formula 637.7 g, p = 0.048), lean body mass (LM) (2512 g, 2853 g, 2722 g, respectively, p = 0.009) and lean mass index (LMI) (10.6 kg/m², 11.6 kg/m²,11.2 kg/m² respectively, p = 0.008) at TEA, but not 3mCA. Breastfed infants demonstrated greater increase in LM (breast 1707 g, mixed 1536 g, formula 1384 g, p = 0.03) and LMI (1.23 kg/m², 0.10 kg/m², 0.52 kg/m², respectively, p = 0.022) between TEA and 3mCA.

CONCLUSIONS

Breastfed LMPT infants have lower FM and greater LM increase and LMI increase up to 3mCA compared to formula or mixed-fed infants. These findings stress the importance of supporting breastfeeding in this population.

IMPACT

Infants born late and moderate preterm age who are exclusively breastfed soon after birth gain more lean mass up to 3 months corrected age compared to mixed- or formula-fed infants. Breastfed infants have lower lean and fat mass at term equivalent age compared to mixed- and formula-fed infants. This is the first study exploring this population's growth and body composition in detail at 3 months corrected age. Our results underline the importance of supporting mothers to initiate and continue breastfeeding at least until 3 months corrected age.

Breastfeeding in Neonates Admitted to an NICU: 18-Month Follow-Up

Introduction: The admission of neonates to Neonatal Intensive Care Units (NICUs) has been identified as a primary inhibiting factor in the establishment of breastfeeding. The aims of this study were to (1) estimate the prevalence and duration of breastfeeding in infants/toddlers who had been admitted to an NICU in Greece and (2) to investigate factors, associated with the NICU stay, which affected the establishment and maintenance of breastfeeding in infants/toddlers previously admitted to the NICU. Materials and methods: Data for this cohort study were retrieved from interviews with mothers of infants/toddlers who had been admitted to our NICU as neonates during the period of 2017−2019. Interviews were conducted based on a questionnaire regarding the child’s nutrition from birth to the day of the interview, including previous maternal experience with breastfeeding. Information related to the prenatal period, gestation age, delivery mode, duration of NICU stay, and neonatal feeding strategies during their hospital stay were recorded. Results: The response rate to the telephone interviews was 57%, resulting in 279 mother−infant pairs being included in this study. The results showed that 78.1% of children received maternal milk during their first days of life. Of all infants, 58.1% were exclusively breastfed during their first month, with a gradual decrease to 36.9% and 19.4% by the end of the third and sixth months of life, respectively. The prevalence of breastfed children reached 14.7% and 7.5% at the ages of twelve and eighteen months, respectively. In the multivariate analysis, prematurity emerged as an independent prognostic factor for the duration of exclusive and any breastfeeding (aHR 1.64, 95% CI: 1.03−2.62; and 1.69, 95% CI: 1.05−2.72, respectively; p < 0.05). Additionally, the nationality of the mother, NICU breastfeeding experience, the administration of maternal milk during neonatal hospital stay, and previous breastfeeding experience of the mother were independent prognostic factors for the duration of breastfeeding. Conclusions: Although breastfeeding is a top priority in our NICU, the exclusive-breastfeeding rates at 6 months were quite low for the hospitalized neonates, not reaching World Health Organization (WHO) recommendations. Mothers/families of hospitalized neonates should receive integrated psychological and practical breastfeeding support and guidance.

Breastfeeding initiation, duration, and experiences of mothers of late preterm twins: a mixed-methods study

Background

Twins and late preterm (LPT) infants are at an increased risk of being breastfed to a lesser extent than term singletons. This study aimed to describe the initiation and duration of any and exclusive breastfeeding at the breast for mothers of LPT twins and term twins during the first 4 months and to explore the breastfeeding experiences of mothers of LPT twins.

Methods

A sequential two-sample quantitative–qualitative explanatory mixed-methods design was used. The quantitative data were derived from a longitudinal cohort study in which 22 mothers of LPT twins and 41 mothers of term twins answered questionnaires at one and four months after birth (2015–2017). The qualitative data were obtained from semi-structured interviews with 14 mothers of LPT twins (2020–2021), based on results from the quantitative study and literature. Analysis included descriptive statistics of quantitative data and deductive content analysis of the qualitative data, followed by condensation and synthesis.

Results

All mothers of LPT twins (100%) and most mothers of term twins (96%) initiated breastfeeding. There was no difference in any breastfeeding during the first week at home (98% versus 95%) and at 1 month (88% versus 85%). However, at 4 months, the difference was significant (44% versus 75%). The qualitative data highlighted that mothers of LPT twins experienced breastfeeding as complex and strenuous. Key factors influencing mothers’ experiences and decisions were their infants’ immature breastfeeding behaviors requiring them to express breast milk alongside breastfeeding, the burden of following task-oriented feeding regimes, and the lack of guidance from healthcare professionals. As a result, mothers started to question the worth of their breastfeeding efforts, leading to changes in breastfeeding management with diverse results. Support from fathers and grandparents positively influenced sustained breastfeeding.

Conclusions

Mothers of LPT twins want to breastfeed, but they face many challenges in breastfeeding during the first month, leading to more LPT twins’ mothers than term twins’ mothers ceasing breastfeeding during the following months. To promote and safeguard breastfeeding in this vulnerable group, care must be differentiated from routine term infant services, and healthcare professionals need to receive proper education and training.

Breastfeeding challenges and support in a high initiation population

BACKGROUND

The breastfeeding initiation rate in Israel is approximately 90%, yet exclusive breastfeeding drops sharply in the early postnatal period. The study objective was to assess early postpartum professional breastfeeding support, its association with breastfeeding success and identification of risk factors for early breastfeeding discontinuation.

METHODS

As part of a post-discharge newborn follow-up study, a convenience sample of 868 mothers attending Maternal and Child Health Centers (MCHCs) up to three months post-partum were interviewed using a 26-item questionnaire. Breastfeeding-related questions covered demographic variables, pregnancy and birth details; breastfeeding duration, lactation support in hospital and post-discharge; and problems experienced.

RESULTS

Most mothers, 797 (91.8%), initiated breastfeeding in hospital. All women who initiated breastfeeding in the hospital reported exclusive breastfeeding; by two weeks postpartum, 70 women (13.2%) were supplementing with formula (partial breastfeeding). Kaplan-Meier Survival Analysis revealed an estimated mean duration of exclusive breastfeeding in the sample population of 66.8 ± 1.5 days. This duration was shorter for women with preterm births, low birthweight infants (LBW), cesarean births, and hospitalizations in neonatal intensive care units (NICU). A total of 472 (59.3%) breastfeeding mothers reported receiving in-hospital guidance. Of these, 290 (61.3%) were observed breastfeeding. Of all women who initiated breastfeeding, 280 (35.1%) attended MCHC follow-up within 72 h of hospital discharge. A higher proportion of women experiencing breastfeeding difficulties attended an MCHC within 72 h (131/297, 44.1%) compared to women not experiencing difficulties (148/499, 29.7%). The most frequently reported problems were mechanical (55.2%) or milk supply concerns (18.5%). First-time mothers were more likely to report problems, as were Jewish (vs Arab) mothers.

CONCLUSIONS

Even in a population with high initiation rates of breastfeeding, breastfeeding duration, both exclusive and partial, is less than recommended. As much of this drop-off occurs during maternity leave, it is likely related to breastfeeding challenges other than employment. Breastfeeding support needs of women are currently not adequately met; staffing and time for both in-hospital and community-based counseling needs to be funded as well as mandated. Counseling hours should be tailored to assure adequate coverage of high-risk groups such as women after cesarean delivery and newborns requiring intensive care.

Encourage, Assess, Transition (EAT): A Quality Improvement Project Implementing a Direct Breastfeeding Protocol for Preterm Hospitalized Infants

BACKGROUND

The opportunity to establish a direct breastfeeding (DBF) relationship with a preterm infant, if desired by the mother or lactating parent, is a known driver of positive healthcare experiences. Preterm birth is an independent risk factor for early human milk (HM) cessation, and DBF at the first oral meal promotes continued DBF during hospitalization and HM duration beyond discharge. While the Spatz 10-step model for protecting and promoting HM and breastfeeding in vulnerable infants provides best practices, lack of standardized implementation results in missed opportunities to meet parents' DBF goals.

PURPOSE

To standardize clinical practices to increase DBF at the first oral meal, total DBF meals during hospitalization, and use of test weighing to measure milk transfer for preterm infants.

METHODS

Quality improvement methods were used to develop and implement Encourage, Assess, Transition (EAT): a DBF protocol for infants less than 37 weeks gestation at birth, in a level II neonatal intensive care unit.

RESULTS

Thirty-eight (45%) infants from 27.7 to 36.7 weeks of gestation initiated the protocol. The proportion of infants' DBF at first oral meal increased from 22% to 54%; mean DBF meals during hospitalization increased from 13.3 to 20.3; and use of test weighing increased by 166%.

IMPLICATIONS FOR PRACTICE AND RESEARCH

Standardizing DBF practices with the EAT protocol increased DBF during hospitalization-a known driver of patient experience-and HM duration beyond discharge, in hospitalized preterm infants. Researchers should validate the reported benefits of EAT (increased DBF during hospitalization, use of test weighing, and improved patient experience), methods to promote passive dissemination of evidence, and sustain change.Video abstract available at: https://journals.na.lww.com/advancesinneonatalcare/pages/videogallery.aspx?autoPlay=false&videoId=61.

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.

Relationship Between Maternal COVID-19 Infection and In-Hospital Exclusive Breastfeeding for Term Newborns

Objective

To evaluate the relationship between maternal COVID-19 infection and the odds of in-hospital exclusive breastfeeding for term newborns.

Design

Retrospective descriptive quantitative.

Setting

A large, urban hospital with more than 6,000 births annually.

Sample

Term newborns born between March 1, 2020, and March 31, 2021 (N = 6,151).

Methods

We retrospectively extracted data from electronic health records to evaluate the relationship of maternal COVID-19 infection with the odds of in-hospital exclusive breastfeeding using univariate analysis and logistic regression models. The covariates included insurance type, race/ethnicity, glucose gel administration, length of stay, newborn gestational age, newborn birth weight, and maternal COVID-19 infection.

Results

Maternal COVID-19 infection was not significantly related to the odds of in-hospital exclusive breastfeeding (p = .138) after adjustment for covariates in the logistic regression model. However, when newborns who received pasteurized donor human milk supplementation were excluded from the logistic regression model, maternal COVID-19 infection significantly decreased the odds of in-hospital exclusive breastfeeding (p = .043).

Conclusion

Maternal COVID-19 infection was not significantly related to the odds of in-hospital exclusive breastfeeding when newborns received donor human milk supplementation. Access to donor human milk for supplementation for term newborns may protect the odds of in-hospital exclusive breastfeeding.

Factors associated with post NICU discharge exclusive breastfeeding rate and duration amongst first time mothers of preterm infants in Shanghai: a longitudinal cohort study

BACKGROUND

Breastfeeding is crucial for the preterm infants. Breast milk is not only food but also medicine. Few studies have focused on the longitudinal effects of exclusive breastfeeding outcome of preterm infants separated from their mothers after discharge, especially in Shanghai. We aimed to examine the exclusive breastfeeding rate and duration amongst first time mothers of preterm infants after discharge and its determinants.

METHODS

Analyses were based on 500 preterm infants separated from their mothers in a tertiary maternity and infant-specialized hospital in Shanghai from September 2018 to September 2019.The Socio-demographic characteristics, breastfeeding knowledge questionnaire, breastfeeding self-efficacy short form scale, Edinburgh postpartum depression scale and breastfeeding family support scale were used for the investigation and the exclusive breastfeeding rate of premature infants was followed up on 1 month, 3 months and 6 months after discharge. The changing trend of breastfeeding knowledge, breastfeeding self-efficacy, postpartum depression and family support were measured by ANOVA at different stages. Using the chi-square test and multiple logistic regression, factors impacting the breastfeeding rate of preterm infants at three time intervals after discharge were investigated. The Kaplan Meier survival curve and cox regression model were used to analyze the determinants of exclusive breastfeeding duration of premature infants after discharge.

RESULTS

Exclusive breastfeeding rates were 19.0, 17.2 and 10.4% at 1 month, 3 months and 6 months after discharge of preterm infants, respectively. The average length of exclusive breastfeeding duration was(3.69 ± 1.80)months. Finally, type of delivery (adjusted odds ratio [AOR] 1.564; 95% confidence interval [CI] 0.513,3.116), gestational age(AOR 0.612, 95% CI 0.236, 3.418), maternal family support (AOR 6.125,95% CI 6.359, 98.452) were discovered to be independent predictors on the exclusive breastfeeding rate at 6 months after preterm infants were discharged. Through the cox regression model, we found that a maternal planned pregnancy (HR 0.681, 95%CI 0.531,0.873), delivering breast milk during hospitalization (HR 0.797, 95%CI 0.412,2.288), NICU feeding mode during hospitalization (HR 1.221, 95%CI 0.128,1.381) and family support (HR 0.561, 95%CI 0.004,2.428) were significantly associated with the exclusive breastfeeding duration after discharge.

CONCLUSIONS

The exclusive breastfeeding outcome of premature infants was affected by many factors, so we should focus on the three levels of individual, family, society and design targeted intervention measures to increase the exclusive breastfeeding rate and prolong exclusive breastfeeding duration.

Application of the screening test principles to screening for neonatal hypoglycemia

Severe and prolonged neonatal hypoglycemia can cause brain injury, while the long-term consequences of mild or transitional hypoglycemia are uncertain. As neonatal hypoglycemia is often asymptomatic it is routine practice to screen infants considered at risk, including infants of mothers with diabetes and those born preterm, small or large, with serial blood tests over the first 12-24 h after birth. However, to prevent brain injury, the gold standard would be to determine if an infant has neuroglycopenia, for which currently there is not a diagnostic test. Therefore, screening of infants at risk for neonatal hypoglycemia with blood glucose monitoring does not meet several screening test principles. Specifically, the long-term neurodevelopmental outcomes of transient neonatal hypoglycemia are not well understood and there is no direct evidence from randomized controlled trials that treatment of hypoglycemia improves long-term neurodevelopmental outcomes. There have been no studies that have compared the long-term neurodevelopmental outcomes of at-risk infants screened for neonatal hypoglycemia and those not screened. However, screening infants at risk of hypoglycemia and treating those with hypoglycaemic episodes to maintain the blood glucose concentrations ≥2.6 mmol/L appears to preserve cognitive function compared to those without episodes. This narrative review explores the evidence for screening for neonatal hypoglycemia, the effectiveness of blood glucose screening as a screening test and recommend future research areas to improve screening for neonatal hypoglycemia. Screening babies at-risk of neonatal hypoglycemia continues to be necessary, but as over a quarter of all infants may be screened for neonatal hypoglycemia, further research is urgently needed to determine the optimal method of screening and which infants would benefit from screening and treatment.

The Effect of Kangaroo Care on Breastfeeding and Development in Preterm Neonates

PURPOSE

This study investigated the effect of kangaroo care (KC) on breastfeeding rate and development in preterm neonates in the first six months of life.

DESIGN

The study was conducted using a quasi-experimental method with a pretest-posttest control group design. The sample consisted of preterm neonates in the NICU of two state hospitals of Turkey. The experimental group (n =30) was provided with KC by their mothers for 30 min once a day during a postnatal month. The control group (n = 30) received routine care. Feeding patterns and physical development parameters were determined during the transition to exclusive breastfeeding and at discharge, and in the first, third, and sixth postnatal months. Data were collected using a descriptive characteristics questionnaire, a nutrition and physical development follow-up form, and a home KC follow-up form. Percentage distribution, mean, chi-square test, and t-test were used for analysis.

RESULTS

The KC group had a significantly higher mean body weight than the control group in the third and sixth postnatal months (p < .05). The KC group had higher breast milk intake and breastfeeding rates than the control group during the transition to exclusive breastfeeding and at discharge, and in the first, third, and sixth postnatal months (p < .05).

CONCLUSION

The KC neonates were breastfed for a more extended period of time than controls. This result suggests that KC improves breast milk intake and breastfeeding rates. Therefore, mothers should be trained in KC in the postnatal period.

PRACTICE IMPLICATIONS

Healthcare professionals should encourage and follow mothers for kangaroo care.

Strategies to improve neurodevelopmental outcomes in babies at risk of neonatal hypoglycaemia

Neonatal hypoglycaemia is associated with adverse development, particularly visual-motor and executive function impairment, in childhood. As neonatal hypoglycaemia is common and frequently asymptomatic in at-risk babies-ie, those born preterm, small or large for gestational age, or to mothers with diabetes, it is recommended that these babies are screened for hypoglycaemia in the first 1-2 days after birth with frequent blood glucose measurements. Neonatal hypoglycaemia can be prevented and treated with buccal dextrose gel, and it is also common to treat babies with hypoglycaemia with infant formula and intravenous dextrose. However, it is uncertain if screening, prophylaxis, or treatment improves long-term outcomes of babies at risk of neonatal hypoglycaemia. This narrative review assesses the latest evidence for screening, prophylaxis, and treatment of neonates at risk of hypoglycaemia to improve long-term neurodevelopmental outcomes.

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.

A shorter breastfeeding duration in late preterm infants than term infants during the first year

AIM

Little attention has been paid to breastfeeding late preterm (LPT) infants. This study compared breastfeeding, worries, depression and stress in mothers of LPT and term-born infants throughout the first year. We also described factors associated with shorter breastfeeding duration of LPT infants.

METHODS

This longitudinal cohort study of the mothers of singleton infants-129 born LPT and 277 born at term-was conducted at Landspitali-The National University Hospital of Iceland, which has the country's only neonatal intensive care unit. The mothers answered questionnaires when their infants were 1, 4, 8 and 12 months of age.

RESULTS

Mothers breastfed LPT infants for a significantly shorter time than term infants: a median of 7 months (95% confidence interval 5.53-8.48) vs 9 months (95% confidence interval 8.39-9.61) (P < .05). Starting solids at up to 4 months was the strongest risk factor for LPT breastfeeding cessation during the first year, after adjusting for confounders (P < .001). Their mothers reported more worries about their infants' health and behaviour during the first year and were more likely to experience depression at 4 months.

CONCLUSION

Mothers with LPT infants are vulnerable and need greater practical breastfeeding and emotional support in hospital and at home.

Longitudinal Study Depicting Differences in Complementary Feeding and Anthropometric Parameters in Late Preterm Infants up to 2 Years of Age

Ensuring the nutritional demands of preterm (PT) infants during complementary feeding could contribute significantly to the infants’ long-term health and development. However, the dietary guidelines for complementary feeding in PT are scarce. Thus, describing dietary intake and identifying nutritional targets for these infants could be of great interest. The aim of this study is to assess the food intake and anthropometric parameters in a Mediterranean infant cohort from 6 to 24 months and to identify nutritional targets especially focused on late preterm infants. This is a longitudinal prospective study analyzing information from administered questionnaires about general characteristics and food frequency consumption in 115 infants (20 PT (32 to 36 gestational weeks), 95 full-term (FT)) at 6, 12 and 24 months of age. Results show that the differences in the prevalence of underweight observed in PT infants vs. FT infants are maintained for up to 6 months of age but disappear at 12 and 24 months. The age of inclusion of new foods and the average intake of the main food groups was not different from that of FTs. Although protein intake at 6 months was directly correlated with weight gain and growth in FT, these associations were not observed in PT. At the nutritional level, the low intake of vitamin D in preterm infants is noteworthy. These findings may be useful when designing new intervention strategies for this population group.

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.

Effects of in-hospital breast feeding on brain function development in preterm infants in China: study protocol for a prospective longitudinal cohort study

INTRODUCTION

Due to immature brain development, preterm infants are more likely to develop neurological developmental defects compared with full-term infants. Most preterm infants without neurodevelopmental damage can eventually reach the same scholastic level as their same-age peers; however, some show persistent impairment. Breast feeding (BF), which is an important public health measure, is of great significance for preterm infants. Various active substances in breast milk promote the development of the brain and central nervous system in premature infants. We present a protocol for a prospective longitudinal cohort study to explore the effect of in-hospital BF on brain development in preterm infants and possible influencing factors.

METHODS AND ANALYSIS

This study will enrol 247 Chinese preterm infants (gestational age: 30-34 weeks) delivered in Women's Hospital School of Medicine, Zhejiang University, and transferred to the neonatal intensive care unit. Demographic, clinical and in-hospital BF data will be collected through electronic medical records. Moreover, follow-up data will be obtained by telephone, interview or online. Measurements will be obtained using the Breastfeeding Self-Efficacy Scale-Short Form, neuroimaging with functional near-infrared spectroscopy, extrauterine growth restriction and the Ages and Stages Questionnaire. Follow-up will be performed at 3, 6 and 12 months after birth.

ETHICS AND DISSEMINATION

This study has been approved by the Women's Hospital School of Medicine Zhejiang University Medical Ethics Committee (2019-058). The study results are expected to be published in peer-reviewed journals and reported at relevant national and international conferences.

Does breastfeeding self-efficacy theory apply to mothers of moderate and late preterm infants? A qualitative exploration

BACKGROUND

Breastmilk feeding reduces morbidities and improves outcomes related to prematurity. However, breastmilk feeding rates in preterm infants are substantially lower than those in term infants. Breastfeeding self-efficacy theory is a social change theory, which is predictive of exclusive breastmilk feeding at 2 months postpartum in mothers of full-term infants. However, this theory has not been well explored in mothers of moderate and late preterm infants.

AIMS AND OBJECTIVES

To explore maternal experiences with feeding moderate (32^0/7 - 33^6/7  weeks' gestational age) and late preterm infants (34^0/7 - 36^6/7  weeks' GA) in neonatal intensive care units and assess applicability of breastfeeding self-efficacy theory.

METHODS

We conducted a qualitative descriptive exploration of maternal experiences with infant feeding in neonatal intensive care units. Using purposive, maximum variation sampling, we selected mothers of preterm infants born at 32^0/7 - 34^6/7  weeks, who experienced high mean differences in their BSE scores between admission and discharge. Fourteen mothers participated in semi-structured telephone interviews. Data were examined using thematic analysis. To explore and describe breastfeeding self-efficacy within the context of neonatal intensive care units, we super-imposed the four sources of information from breastfeeding self-efficacy theory onto the defined themes.

RESULTS

Three main themes emerged: (a) institutional influences, (b) relationship with the pump and (c) establishing breastfeeding, with an emphasis on the importance of direct breastfeeding at discharge. Overlaying the four sources of information from breastfeeding self-efficacy highlighted the presence of three sources of information: verbal persuasion, performance accomplishment and physiologic/affective responses. Vicarious experience was not identified in maternal experiences with infant feeding.

CONCLUSION

Our findings indicate that breastfeeding self-efficacy is an applicable theory for mothers of preterm infants.

RELEVANCE TO CLINICAL PRACTICE

Healthcare providers need to be aware of the influence that institutional culture and policies may have on maternal breastfeeding self-efficacy 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.
