Changes in the prevalence of breast feeding in preterm infants discharged from neonatal units: a register study over 10 years

The relationship of milk expression pattern and lactation outcomes after very premature birth: A cohort study

INTRODUCTION

Mothers of very premature infants often have difficulties expressing breastmilk, which can cause distress and potential negative impact on infant health. Clinical recommendations on breastmilk expression are extrapolated from term infants' breastfeeding patterns. This study's objective was to analyse the association of expressing pattern with lactation outcomes after very premature birth.

METHODS

132 participants were recruited after birth between 23+0 and 31+6 weeks' gestation. Participants recorded the milk expressed in several 24-hour periods in the three weeks after birth.

RESULTS

Expressing frequency was positively associated with 24-hour milk yield, with an adjusted 30.5g increase per expressing session on day four (95% CI 15.7 to 45.3) and 94.4g on day 21 (95% CI 62.7 to 126.2). Expressing ≥8 times per day was associated with higher adjusted milk yield than expressing <6 times (on day four, 146.8g, 95% CI 47.4 to 246.1), but not in comparison to expressing 6-7 times (on day four, 82.1g, 95% CI -25.9 to 190.1). Participants with six months or more prior breastmilk feeding experience had a higher adjusted milk yield than others (on day four, 204.3g, 95% CI 125.2 to 283.3). Night-time (2300-0700 hours) expressing sessions were not associated with increased milk yield after adjustment for time since the prior session. On average, participants who had a longest gap between expressions of less than six hours achieved the UK target of 750g breastmilk, whereas those with a longer gap did not.

CONCLUSION

Expressing frequency was an important determinant of milk yield. Clinical recommendations to express ≥8 times per day were supported but for some, 6-7 times was sufficient. This was particularly likely for those with six months or more of prior breastmilk feeding experience. A need to express during the night-time hours appeared to be related to minimising the gap between expressions rather than an inherent value of night-time expression.

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.

A structured programme to promote breastfeeding improved the rates in very preterm infants at discharge

AIM

We developed the Promotion of Breastfeeding (PROBREAST) programme and evaluated what effect it had on the breastfeeding rate in infants born at less than 32 weeks of gestation or weighing ≤1500 grams.

METHODS

We compared the breastfeeding rate in two cohorts of patients who were born before (n = 72; January 2017 to June 2018) and after (n = 80; July 2018 to December 2019) the application of the programme. Moreover, we compared the correlation between type of feeding at discharge and post-discharge breastfeeding rate, between exclusive breastfeeding, postnatal growth and neurodevelopment.

RESULTS

Infants in the PROBREAST group had an exclusive breastfeeding rate at discharge higher (42 vs. 16%, p < 0.001) than that in the historical control group. Exclusive breastfeeding was negatively correlated with weight z-score at discharge, but not at 12 and 24 months corrected age, and was positively correlated with cognitive score at 24 months corrected age.

CONCLUSION

The application of a structured programme for the promotion of breastfeeding improved the breastfeeding rate in very preterm infants. We demonstrated that exclusive breastfeeding at discharge improved their neurodevelopment without impairing growth.

Factors Associated with Low Volumes of Mother's Own Milk at Neonatal Intensive Care Unit Discharge of Very Low Birth Weight Infants-a Cohort Study

Background: Mother's own milk (MOM) provides health benefits for infants with very low birth weight (VLBW). This study aimed to describe the incidence and factors associated with low volumes of MOM (<50% of total diet volume) at discharge for VLBW infants. Methods: A prospective cohort study of infants with VLBW and gestational age of <30 weeks, who survived to discharge and had no contraindication to MOM. We conducted bivariate analyses to investigate associations with the volume of MOM at discharge, using chi-square, t, and Mann-Whitney tests. All p-value analyses were two-tailed. The variables significantly associated with "low volumes of MOM" entered the multivariable analysis. Univariate and multivariate relative risk (confidence interval [CI] 95%) estimates were obtained from Poisson regression with a robust estimate of variance and controlled by the length of hospital stay. Results: Of 414 infants included and followed until discharge, 32.9% (n = 136) received less than 50% of the total daily volume of MOM. This outcome was associated with gestational age <28 weeks, lower birth weight, multiple births, developing bronchopulmonary dysplasia, and longer lengths of stay. After Poisson regression, low volumes of MOM at discharge were associated only with being born multiples (RR 2.01; CI 95% 1.53-2.64, p < 0.001) and with longer length of stay (RR 1.07; CI 95% 1.01-1.14, p = 0.01). Conclusions: Most VLBW infants were discharged home receiving predominantly MOM. Each neonatal intensive care unit (NICU) should acknowledge which clinical characteristics of mothers and VLBW infants are associated with difficulties maintaining MOM volumes until discharge.

Breastfeeding in primiparous women with congenital heart disease - a register study

BACKGROUND

The number of pregnant women with congenital heart disease (CHD) is rising, and the disease poses increased risks of cardiovascular and obstetric complications during pregnancy, potentially impacting breastfeeding success. This study aimed to investigate breastfeeding in primiparous women with CHD compared to primiparous women without CHD, and to examine potential hindering factors for breastfeeding in women with CHD.

METHODS

The data were gathered between 2014 and 2019 and obtained by merging the Swedish Congenital Heart Disease Register (SWEDCON) with the Swedish Pregnancy Register. Primiparous women ≥ 18 years of age with CHD (n = 578) were matched by age and municipality to 3049 women without CHD, giving birth after 22 gestational weeks. Multivariable logistic regression analysis was used to identify factors associated with non-breastfeeding in women with CHD.

RESULTS

Fewer women with CHD breastfed than women without CHD two days (94% vs. 97%, p = 0.001) and four weeks after birth (84% vs. 89%, p = 0.006). When all women were analysed, having CHD was associated with non-breastfeeding at both two days and four weeks after birth. For women with CHD, body mass index (BMI) ≥ 30 (OR 3.1; 95% CI 1.4, 7.3), preterm birth (OR 6.4; 95% CI 2.1, 19.0), self-reported history of psychiatric illness (OR 2.4; 95% CI 1.2, 5.1), small for gestational age (OR 4.2; 95% CI 1.4, 12.2), and New York Heart Association Stages of Heart Failure class II - III (OR 6.0; 95% CI 1.4, 26.7) were associated with non-breastfeeding two days after birth. Four weeks after birth, factors associated with non-breastfeeding were BMI ≥ 30 (OR 4.3; 95% CI 2.1, 9.0), self-reported history of psychiatric illness (OR 2.2; 95% CI 1.2, 4.2), and preterm birth (OR 8.9; 95% CI 2.8, 27.9).

CONCLUSIONS

The study shows that most women with CHD breastfeed, however, at a slightly lower proportion compared to women without CHD. In addition, factors related to the heart disease were not associated with non-breastfeeding four weeks after birth. Since preterm birth, BMI ≥ 30, and psychiatric illness are associated with non-breastfeeding, healthcare professionals should provide greater support to women with CHD having these conditions.

Monitoring the Use of Human Milk, the Ideal Food for Very Low-Birth-Weight Infants-A Narrative Review

Aware of the utmost importance of feeding premature babies-especially those of lower weight-with human milk, as well as the need to monitor this important element of neonatal care, we focused on four aspects in this review. First of all, we reviewed the beneficial effects of feeding premature infants with breast milk in the short and long term. Secondly, we performed a quantitative evaluation of the rates of breastfeeding and feeding with human milk in Very-Low-Birth-Weight infants (VLBWs) during hospitalization in the Neonatal Intensive Care Unit (NICU) and at discharge. Our aim was to take a snapshot of the current status of human milk-feeding care and track its trends over time. Then we analyzed, on the one hand, factors that have been proven to facilitate the use of maternal milk and, on the other hand, the risk factors of not feeding with breast milk. We also considered the spread of human milk banking so as to assess the availability of donated milk for the most vulnerable category of premature babies. Finally, we proposed a protocol designed as a tool for the systematic monitoring of actions that could be planned and implemented in NICUs in order to achieve the goal of feeding even more VLBWs with human milk.

Factors affecting breastfeeding self-efficacy among mothers with preterm infants

BACKGROUND

Although challenges in breastfeeding are more common in mothers of preterm infants, maternal breastfeeding self-efficacy is a modifiable factor that may improve breastfeeding rates.

OBJECTIVE

To evaluate the factors affecting breastfeeding self-efficacy among mothers with preterm babies.

DESIGN

A cross-sectional study.

METHODS

This study was carried out using a double-stage cluster sampling method. In total, 360 mothers of preterm infants under 6 months of age were included. Data were collected using sociodemographic characteristics, Breastfeeding Self-efficacy Scale-Short Form (BSES-SF), multiple scales of perceived social support, and Depression, Anxiety, and Stress questionnaires.

RESULTS

The results showed social support (15.6%), depression (12.2%), anxiety (11%), and stress (12.2%) contributed independently, and together they explained 25% of the variance in BSES-SF. The higher levels of social support (β = 0.283), lower levels of mental health problems (β = -0.340), having breastfeeding experience (β = -0.253), and higher gestational age at birth (β = 0.106) were significantly related to the high level of BSES-SF.

CONCLUSION

These findings can help healthcare providers be aware of effective factors in improving breastfeeding self-efficacy. Increased access to counselors, active support for mothers after preterm labor, and increased support facilities for mothers with preterm delivery may be helpful to improve breastfeeding self-efficacy.

Breastfeeding needs of mothers of preterm infants in China: a qualitative study informed by the behaviour change wheel

BACKGROUND

Although breastfeeding is strongly recommended, the breastfeeding rate of preterm infants in China remains significantly low. In addition to the global structural challenges to breastfeeding and the physiological immaturity of preterm infants, Chinese mothers of preterm infants face unique challenges of maternal-infant separation after birth. Moreover, little is known about Chinese mothers' specific needs in coping with the difficulties posed by these challenges. This study utilized the Behaviour Change Wheel to investigate the breastfeeding needs of Chinese preterm mothers that may facilitate its practice in the future.

METHOD

A qualitative descriptive design was implemented in Wuhan in 2022. Based on purposeful sampling, 13 preterm mothers were recruited from a NICU in a Grade III Class A hospital in Wuhan, China. Face-to-face semi-structured interviews were conducted to collect data using the interview guide developed by the Theoretical Domains Framework. Theoretical Thematic Analysis was used to review the data in 6 steps to identify themes.

RESULTS

Five major themes emerged: (1) capability: ability to interpret infants' cues and identify problems, and need for breastfeeding knowledge and skills training; (2) physical opportunity: cleanliness and quietness in household environment, private lactation spaces and breastfeeding tools in workplaces and hospitals; (3) social opportunity: family support, peer support, and authoritative support from healthcare providers; (4) reflective motivation: information on health impacts of breastfeeding; (5) automatic motivation: maternal-infant bonding, free of aversive stimulus.

CONCLUSION

Preterm mothers' needs to enable breastfeeding were diverse, including increasing their capability, physical and social opportunities, and reflective and automatic motivation. People, resources and environments associated with these needs should be engaged together to stablish a conducive structural environment for breastfeeding. The policy change for "zero separation" and implementation of kangaroo care should also be implemented in Chinese neonatal intensive care units. Future studies are needed to design effective interventions according to mothers' specific needs.

Trend and Predictors of Breastmilk Feeding among Very-Low-Birth-Weight Infants in NICU and at Discharge

Mothers' own milk (MOM) for premature babies is considered a life-saving drug for its proven protective action against the complications of prematurity and for effects on outcome in the short and long term, especially neurological ones. We studied the use of MOM for infants weighing <1500 g for a period of 5 years, evaluating the trend over time and the impact of some variables on human milk feeding performance. Statistical comparisons concerned the rate of feeding with breast milk during a stay in an NICU and at discharge with respect to two types of variables: (1) maternal and neonatal characteristics (gestational age, birth weight, type of pregnancy (whether single or twin), maternal age) and (2) feeding characteristics (time of the start of minimal enteral feeding and availability of MOM, days until the achievement of full enteral feeding). Group comparisons were performed using ANOVA or t-test for continuous variables and Pearson chi-squared test or Fisher exact test for categorical variables. We observed an increase, between 2017 and 2021, in MOM use (p = 0.003). The availability of the own mothers' milk occurred, on average, on the fourth day of life and improved over the years. The start of minimal enteral feeding (MEF) with human milk averaged 1.78 days, and 54.3% of VLBWs received MEF with donor milk on the first day of life. The average percentage of feeding with the mothers' milk at discharge was 47.6%, with 36.1% of exclusive MOM and an increase from 45.8% in 2017 (33.3% exclusive) to 58.82% (41.18% exclusive) in 2021. The mean average daily growth of the weight improved (p < 0.001) during this period, and there was no statistical difference between infants fed with maternal milk and those fed with bank milk. Older maternal age, early-start feeding with maternal milk and low gestational age had a statistically significant impact on feeding with MOM at discharge.

Skin to Skin Contact Correlated with Improved Production and Consumption of Mother's Own Milk

Background: Human milk diet, preferably mother's own milk (MOM) over donor milk (DM), is recommended for preterm infants. Expression of MOM in proximity to preterm infants, especially during or immediately after skin-to-skin contact (SSC), is associated with greater milk production. However, the correlation between SSC and MOM production during hospital admission in preterm infants has not yet been studied. Our study investigated the relationship between SSC and MOM production and consumption in preterm infants during the first postnatal month of life. Materials and Methods: This was a prospective cohort study. Mothers and their preterm infants born at <35 weeks by gestational age (GA) and eligible for SSC within the first 5 postnatal days were eligible for the study. Mothers were given a binder to document pumped breast milk volumes and SSC sessions. Pumped breast milk volumes, enteral feeding type and volume, and SSC duration and frequency were collected daily over the first 28 days of life, along with demographic, perinatal, and feeding data from electronic medical records (EMR). Results: Mean birth GA and weight were 30 ± 3 weeks and 1,443 ± 576 g, respectively. SSC duration was inversely correlated with GA and weight. The SSC duration was positively correlated with ingested MOM volume after correcting for birth GA. The SSC duration was predictive of increased volumes of pumped MOM. Conclusion: Our findings suggest that SSC duration is associated with improved MOM production and consumption. SSC can be a useful tool to increase MOM exposure and improve long-term health outcomes in preterm infants.

Exclusive breastfeeding: Relation to gestational age, birth weight, and early neonatal ward admission. A nationwide cohort study of children born after 35 weeks of gestation

OBJECTIVES

Prematurity, being small for gestational age and early neonatal ward admission are the major neonatal conditions that may interfere with breastfeeding supportive practices in infants born at gestational age ≥35+0 weeks. We aimed to investigate the associations between gestational age, small for gestational age, early neonatal ward admission and exclusive breastfeeding at one and four months.

METHODS

A register-based cohort-study of all Danish singletons with gestational age ≥35+0 weeks born in 2014-2015. In Denmark, health visitors routinely conduct free home visits throughout infants' first year and thereby report breastfeeding data to The Danish National Child Health Register. These data were linked with data from other national registers. Logistic regression models estimated the odds ratio for exclusive breastfeeding at one and four months, adjusted for confounding variables.

RESULTS

The study population comprised 106,670 infants. Compared to gestational age 40 weeks, the adjusted odds ratio for exclusive breastfeeding at one month showed a decreasing tendency from gestational age ≥42 (n = 2,282) (1.07; 95% confidence interval (CI) 0.97-1.17) to 36 weeks (n = 2,062) (0.80; 95% CI 0.73-0.88). Small for gestational age (n = 2,342) was associated with decreased adjusted odds ratio for exclusive breastfeeding at one month (0.84; 95% CI 0.77-0.92). Neonatal ward admission was associated with increased adjusted odds ratio for exclusive breastfeeding at one month among late preterm infants (gestational age 35-36 weeks; n = 3,139) (1.31; 95% CI 1.12-1.54), as opposed to among early term (gestational age 37-38 weeks; n = 19,171) (0.84; 95% CI 0.77-0.92) and term infants (gestational age >38 weeks; n = 84,360) (0.89; 95% CI 0.83-0.94). The associations seemed to persist at four months.

CONCLUSIONS

Decreasing gestational age and small for gestational age were associated with decreased exclusive breastfeeding rates. Neonatal ward admission was associated with increased exclusive breastfeeding rates among late preterm infants, whereas the opposite was observed among early term and term infants.

Lactation prescription plus acupoint stimulation improves breastfeeding quality and alleviates breast tenderness in parturients undergoing cesarean section

PURPOSE

This retrospective study primarily discusses the influence of lactation prescription plus acupoint stimulation on breastfeeding quality and breast tenderness of parturients after cesarean section (CS).

METHODS

First, 149 parturients presented between July 2018 and July 2021 for CS were selected, including 74 cases (test group) treated with lactation prescription plus acupoint stimulation and 75 cases (control group) intervened by routine western medicine nursing intervention. The breastfeeding status, milk yield at 48 hours postpartum, breast tenderness (Visual Analogue Scale, VAS), neonatal weight at 42 days after delivery, and laboratory indexes (white blood cell count, WBC; adrenocorticotropin, ACTH; prolactin, PRL) were compared between the two cohorts. Finally, multivariate analysis was carried out using the logistic regression model to identify factors leading to low milk production in mothers 48 hours after CS.

RESULTS

The test group was observed with a higher exclusive breastfeeding rate, higher milk yield at 48 hours postpartum, and milder breast tenderness (lower VAS score) than the control group. Higher neonatal weight at 42 days postpartum was also determined in the test group versus the control group. Moreover, the PRL at 3 days postpartum in the test group was statistically higher than that prenatal and at 1 day postpartum and the control group; markedly elevated WBC and reduced ACTH were observed at 1 d and 3 d postpartum compared with the prenatal, but no significant differences were identified between the test and control groups. According to the Logistic regression analysis, breast tenderness (P=0.009) was an independent risk factor for low lactation in mothers at 48 hours after CS.

CONCLUSION

Lactation prescription plus acupoint stimulation has a positive effect on improving the breastfeeding quality of parturients after CS and relieving breast tenderness, which is worth promoting clinically.

Effects of spousal support in the early postpartum period on breastfeeding motivation in patriarchal societies

Background and Purpose: Breastfeeding is important with regard to public health. Our aim was to examine effects of spousal support in the early postpartum period on breastfeeding motivation in patriarchal societies. Methods: Study was descriptive, cross-sectional, correlational design. Study was conducted in a University Hospital in Inland Anatolia Region in Turkey. It included primiparous and multiparous women. Results: Analysis showed a significant positive, moderate relation between spousal support and breastfeeding motivation in the primiparous women; spousal support accounted for 23.8% of breastfeeding motivation of the women. There was a significant, positive weak relation between spousal support and breastfeeding motivation in the multiparous women; spousal support explained 8.2% of breastfeeding motivation in these women. Conclusion: Spousal support in the early postpartum period was found to have a positive influence on improvement of breastfeeding motivation. However, it could explain a small percentage of breastfeeding motivation. New strategies should be created to encourage spouses to get involved in breastfeeding.

Self-efficacy in breastfeeding predicts how mothers perceive their preterm infant's state-regulation

Background

Mothers of preterm infants often perceive the infant as having problems with crying, sleeping and feeding, sometimes summarised as ‘state-regulation’. Breastfeeding rates are lower among preterm infants, and the mother’s self-efficacy in breastfeeding is central to understanding which mothers are going to breastfeed their infants. We have previously shown that mothers with higher self-efficacy have an easier time adapting to the infant and in this study we hypothesised that the degree of self-efficacy also is associated with how difficult the mother believes it is to take care of the infant. The aim of this study was to investigate whether the late preterm infant’s mother’s self-efficacy in breastfeeding was associated with how the mother experienced her infant’s state-regulation at three months of corrected age.

Methods

The study had a prospective and longitudinal design with a consecutive data collection through questionnaires. Inclusion criteria were mothers (n = 105) with a singleton infant born between 34 + 0 and 36 + 6 weeks of gestation. At term age, the mothers completed the Breastfeeding Self-efficacy Scale-Short Form and at the three months corrected age follow-up, mothers completed the Infant state-regulation index: questions related to whether the infant had difficulties with colic, persistent crying, comforting, falling asleep, sleep problems, breastfeeding, eating or poor weight gain.

Results

The analyses showed that being an older mother, perceiving breastfeeding support, and having a higher breastfeeding self-efficacy were all significantly associated with identifying the infant as having better state-regulation.

Conclusions

There was an association between mothers’ self-efficacy in breastfeeding and her perceptions of how good state-regulation the infant had. This is an important finding, as self-efficacy is a manageable factor that could positively affect how the mother perceives taking care of her infant. Clinical implication: Improved self-efficacy is known to be an important factor in increased breastfeeding prevalence and healthcare professionals should also target mother’s self-efficacy in breastfeeding to improve mother-infant relationship.

Nutrition for the micro preemie: Beyond milk

Nutritional support is a fundamental component of the care of the extremely preterm infant, including the "micro preemie" (here defined as a baby born weighing less than 500 g), but goes beyond considerations of milk as a food. This is because milk from an infant's own mother, unlike currently available substitutes, additionally provides invaluable non-nutritive benefits. Nutritional support requires suitable devices or techniques to administer nutrients enterally or intravenously, products shown to be safe in preterm populations, and efficacy demonstrated in respect of important functional outcomes. Sadly, preterm feeding remains characterised by a deficit of evidence. In this chapter, we will briefly describe the history of preterm nutrition, discuss current enteral and parenteral practice, important evidence gaps, a summary of approaches for evaluating nutritional practice, and key considerations for future endeavour. Our discussion refers to all extremely preterm infants and it not confined to the micro preemie.

A Comparison of the Timing of Hand Expressing of Human Milk With Breast Massage to Standard Care for Mothers of Preterm Infants: An Exploratory Pilot Using a Randomized Controlled Design

BACKGROUND

Globally, 10% of all births are preterm. Access to human milk via manual breast expression is required to reduce the incidence of adverse outcomes related to prematurity. However, there is little evidence to recommend optimum timing to commence breast expression in mothers of preterm infants or the most effective method.

RESEARCH AIMS

(1) To test feasibility of recruitment and compliance to the protocol and (2) to determine influence of using hand expressing and breast massage on milk production, engorgement, mastitis, and breastfeeding status at 3 months.

METHODS

This study was an exploratory parallel two-group, pilot randomized controlled trial. Mothers of preterm infants at a metropolitan maternity hospital in Queensland Australia (N = 31) were randomized to receive either hand expressing and breast massage within the 1st hr of birth or standard care, hand expressing within 6 hr of birth, to determine the influence on milk production, engorgement, mastitis, and breastfeeding status at 3 months.

RESULTS

Feasibility targets were not met; however, valuable learning from this trial uncovered barriers facing midwives in the birth suite to commencing expressing in the 1st hr of birth. There was no difference in occurrence of secondary outcomes, although trends support future study.

CONCLUSIONS

Overall, unpredictability of preterm birth influenced our ability to recruit participants. Important directions for future study design would benefit from incorporating expressing times up to 6 hr with a replicable breast massage.

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.

Prevalence and patterns of gestational parent's own milk feeds among infants with major congenital surgical anomalies in the NICU

OBJECTIVE

To describe the prevalence and patterns of gestational parent's own milk (GPOM) feedings among infants undergoing major surgery during their neonatal intensive care unit (NICU) admission.

STUDY DESIGN

We analyzed de-identified electronic medical records of all infants admitted to a regional NICU 2014-2015 who underwent surgery for a gastrointestinal, cardiac, or other major organ system defect(s).

RESULTS

Of 79 infants, 85% received any GPOM during the NICU hospitalization. The median proportion of GPOM feeds was 66%. There was a trend toward decreassing proportions of GPOM with progressive months in NICU. The rate of any and exclusive GPOM feeds at NICU discharge was 49% and 29%, respectively. Infants who had a GI anomaly were more likely than infants with a cardiac anomaly to be discharged from NICU receiving GPOM.

CONCLUSION

Barriers to the exclusive and continued provision of GPOM in this population require further study and intervention.

Feeding Twins with Human Milk and Factors Associated with Its Duration: A Qualitative and Quantitative Study in Southern Italy

BACKGROUND

Over the past year, there has been a rise in twin births. The current scientific consensus recommended breast-feed milk for all newborns for at least 6 months. They stated that it is possible to meet the nutritional needs of two or more newborns with only one mother's milk. More information would be desirable about the factors that influence or lead to the initiation and interruption of breastfeeding. The quality of the evidence available from multiple studies has been inconclusive and therefore led to controversial interpretations and practices.

AIMS

The first aim of this study was to analyze the extent of the feeding of multiples with breast milk in the experience of our clinical unit in terms of incidence and duration. The second objective was to evaluate the correlation between maternal, perinatal and neonatal variables with breast milk feeding rates and duration.

METHODS

The study was conducted between 2015 and 2020, in a NICU in Southern Italy (San Giovanni Rotondo, Foggia). Sixty-one women who have given birth to multiples were enrolled into the study. Newborn data were retrospectively collected by informatic database and breastfeeding information were collected by a questionnaire.

RESULTS

In our centre, the percentage of twins out of the total number of births over the years has almost doubled from 1.28% in 2015 to 2.48% in 2020 and the 88% of twins are premature. 18.1% received breast milk for more than 6 months and 6.3% received it for more than 12 months. Infants of lower gestational age and weight, born to multiparous, more mature and medium-high schooling mothers received breast milk for a longer period. 35% of women explained that the interruption of breastfeeding was due to the insufficient milk production and 41% to the stress and difficulties in managing the twins. Qualitative analysis of maternal narrative revealed, for many of them, the awareness of the importance of breastfeeding and the efforts made to try to give breast milk, but also fears about the quantity of milk and satiety of their children.

CONCLUSIONS

It is important to identify the factors both favoring and obstructing maternal milk feeding of multiples and it would be desirable the activation of a network of training and support for mothers after discharge, with particular regard to the categories found to be less inclined.

Rates and Determinants of Mother's Own Milk Feeding in Infants Born Very Preterm

OBJECTIVES

To examine rates and determinants of mother's own milk (MOM) feeding at hospital discharge in a cohort of infants born very preterm within the Canadian Neonatal Network (CNN).

STUDY DESIGN

This was a population-based cohort study of infants born at <33 weeks of gestation and admitted to neonatal intensive care units (NICUs) participating in the CNN between January 1, 2015, and December 31, 2018. We examined the rates and determinants of MOM use at discharge home among the participating NICUs. We used multivariable logistic regression analysis to identify independent determinants of MOM feeding.

RESULTS

Among the 6404 infants born very preterm and discharged home during the study period, 4457 (70%) received MOM or MOM supplemented with formula. Rates of MOM feeding at discharge varied from 49% to 87% across NICUs. Determinants associated with MOM feeding at discharge were gestational age 29-32 weeks compared with <26 weeks (aOR 1.56, 95% CI 1.25-1.93), primipara mothers (aOR 2.12, 95% CI 1.86-2.42), maternal diabetes (aOR 0.79, 95% CI 0.66-0.93), and maternal smoking (aOR 0.27, 95% CI 0.19-0.38). Receipt of MOM by day 3 of age was the major predictor of breast milk feeding at discharge (aOR 3.61, 95% CI 3.17-4.12).

CONCLUSIONS

Approximately two-thirds of infants born very preterm received MOM at hospital discharge, and rates varied across NICUs. Supporting mothers to provide breast milk in the first 3 days after birth may be associated with improved MOM feeding rates at discharge.

Associations Between Single-Family Room Care and Breastfeeding Rates in Preterm Infants

BACKGROUND

Hospitalization in neonatal intensive care units with a single-family room design enables continuous maternal presence, but less is known regarding the association with milk production and breastfeeding.

RESEARCH AIM

To compare maternal milk production, breastfeeding self-efficacy, the extent to which infants received mother's milk, and rate of direct breastfeeding in a single-family room to an open bay neonatal intensive care unit.

METHODS

A longitudinal, prospective observational study comparing 77 infants born at 28- 32° weeks gestational age and their 66 mothers (n = 35 infants of n = 30 mothers in single family room and n = 42 infants of n = 36 mothers in open bay). Comparisons were made on milk volume produced, the extent to which infants were fed mother's milk, and rate of direct breastfeeding from birth to 4 months' corrected infant age. Breastfeeding self-efficacy was compared across mothers who directly breastfed at discharge (n = 45).

RESULTS

First expression (6 hr vs. 30 hr, p < .001) and first attempt at breastfeeding (48 hr vs. 109 hr, p < .001) occurred significantly earlier, infants were fed a greater amount of mother's milk (p < .04), and significantly more infants having single-family room care were exclusively directly breastfed from discharge until 4 months' corrected age; OR 6.8 (95% CI [2.4, 19.1]). Volumes of milk produced and breastfeeding self-efficacy did not differ significantly between participants in either units.

CONCLUSION

To increase the extent to which infants are fed mother's own milk and are exclusively directly breastfed, the design of neonatal intensive care units should facilitate continuous maternal presence and privacy for the mother-infant dyad.

Baby-Friendly Hospital Initiative for Neonatal Wards: impact on breastfeeding practices among preterm infants

OBJECTIVE

to assess breastfeeding support practices for preterm infants at two Baby-Friendly hospitals in southeastern Brazil, comparing the effect of implementing the guidelines for Baby-Friendly Hospital Initiative for Neonatal wards.

METHODS

a quasi-experimental study, pre- and post-intervention with control. Implementation of this initiative in the intervention hospital using Knowledge Translation. Data collection on compliance with the adapted Ten Steps, Three Guiding Principles and the Code before and after the intervention was carried out via interviews with mothers of preterm babies and professionals, unit observation and documentary analysis in the intervention and control hospitals. Intra-intergroup comparison was performed.

RESULTS

increases in global compliance with the Three Principles, Ten Steps, the Code, partial compliance with each Principle and in most Steps was greater in the intervention hospital. Conclusion: this initiative improved practices related to breastfeeding in the intervention hospital, demonstrating the potential to improve care and breastfeeding in neonatal wards.

Fathers' experiences of feeding their extremely preterm infants in family-centred neonatal intensive care: a qualitative study

BACKGROUND

Extremely preterm infants need advanced intensive care for survival and are usually not discharged before they reach the time of expected birth. In a family-centred neonatal intensive care unit both parents are involved at all levels of care including the feeding process. However, studies focusing on fathers in this situation are scarce. The purpose of this study was to explore the experiences of feeding extremely preterm infants in a neonatal intensive care unit from fathers' perspectives.

METHODS

The study adopts a qualitative inductive method, reported according to the COREQ checklist. Seven fathers of extremely preterm infants (gestational age 24-27 weeks) in neonatal intensive care in Sweden were interviewed by telephone after discharge in 2013-2014. The interviews were analysed using a qualitative content analysis and confirmed by triangulation in 2021.

RESULTS

Six sub-categories and two generic categories formed the main category: "a team striving towards the same goal". The fathers were equally involved and engaged members of the feeding team all hours of the day. The fathers shared responsibility and practical duties with the mothers, and they provided as much support to the mothers as they could. However, the fathers found it difficult to support and encourage the mothers to breastfeed and express breastmilk when the breastmilk production was low. The fathers experienced a loss when breastfeeding was not successful.

CONCLUSIONS

The findings indicate that fathers want to be involved with infant care, including night-time feeds, and long and demanding feeding processes. Fathers and staff need to collaborate to provide the best support to mothers during the feeding process. This study may inspire hospital staff to acknowledge and support fathers to become more involved in the oral feeding process when an infant is born extremely preterm.

"Liquid Gold" Lactation Bundle and Breastfeeding Rates in Racially Diverse Mothers of Extremely Low-Birth-Weight Infants

Background: In 2015, we implemented a comprehensive lactation bundle named Liquid Gold. Lactation bundles in the neonatal intensive care unit have not been well studied. Materials and Methods: This is an ongoing quality improvement breastfeeding project of racially diverse mothers and infants of extremely low birth weight (≤1,000 g). Four epochs were assessed; baseline (B; January 2012-July 2013), transition (T; human milk [HM]-derived fortifier; August 2013-December 2014), Liquid Gold (LG; full bundle, including staff education, colostrum oral care, kangaroo care, antenatal and postpartum counseling, provision of pasteurized donor HM, and breast pumps; January 2015-February 2016), and current (C; ongoing impact, Spanish-speaking lactation consultant, and HM cream; March 2016-April 2019). Results: Four hundred twenty-three mother-infant dyads were assessed. The rate of exclusive mother's own milk at discharge increased significantly in LG compared with previous epochs and was sustained over time. During LG, African American (AA) mothers had a significant surge of breastfeeding initiation (30% in B and 41% in T versus 78% in LG), but this was not sustained in C. AA mothers also experienced a significant decline in the use of exclusive formula feeding in the C epoch (68% in LG versus 46% in C). Hispanic and White mothers sustained their breastfeeding rates over time. Conclusions: Our Liquid Gold lactation bundle led to a significant increase in the provision of HM in the NICU and at discharge in the most vulnerable infants. AA mothers experienced the highest surge in breastfeeding initiation and greatest reduction in formula use. Breastfeeding goals and support need to be tailored to each mother with specific consideration for racial/ethnic background for optimal success.

Evaluation of an e-Learning Breastfeeding Program for Postpartum Mothers of Moderately High-Risk Newborn Infants Admitted to the Special Care Nursery

Because of a lack of proper breastfeeding education to mothers and the visitation policy in the special care nursery, breastfeeding initiation and maintenance can be very challenging for both the mother and her infant who is admitted to the neonatal special care nursery after birth. Difficulties associated with forming initial bonds may contribute to some mothers changing their mind about their initially chosen feeding method. The aim of this quasi-experimental study was to evaluate the effectiveness of an e-learning breastfeeding program on maternal breastfeeding outcomes. Thirty-four mothers in the comparison group received routine care; 34 in the intervention group received an e-learning breastfeeding program and routine care. The program included 28 modules of different topics downloaded to a personal tablet computer. Each module elaborated on a breastfeeding issue and provided video clips to show practice steps. During the mothers' 3- to 5-day stay in the postpartum unit, they could repeatedly watch selected topics related to their situations at their own pace. After adjusting for each infant's birth weight, mothers in the intervention group had better attachment to their infants, greater perceived nurse support, and a higher exclusive breastfeeding rate than mothers in the comparison group. Using a tablet computer device to disseminate breastfeeding education is a feasible and supplemental method for postpartum mothers whose infants are in the special care nursery. Through the demonstrated situations, mothers are better prepared to understand their high-risk infants and the situations they may encounter during breastfeeding.

Breastfeeding satisfaction post hospital discharge and associated factors - a longitudinal cohort study of mothers of preterm infants

Background

Mothers’ satisfaction with breastfeeding is important for breastfeeding duration but rarely investigated in mothers of preterm infants. The aim of this study was to describe breastfeeding satisfaction and associated factors during the first year in mothers of preterm infants (gestational age < 37 weeks).

Methods

This longitudinal cohort study, based on secondary analysis data from a randomized controlled trial, included 493 mothers of 547 preterm infants. Data on breastfeeding duration and satisfaction, parental stress and attachment were collected at 8 weeks post discharge, and at 6 and 12 months after birth. Breastfeeding satisfaction was measured by the Maternal Breastfeeding Evaluation Scale. Descriptive statistics and linear mixed effect models were used when analyzing the data.

Results

During the first 12 months breastfeeding satisfaction increased in the mean summary scores and points in the dimensions “role attainment” and “lifestyle and maternal body image”. In the dimension “infant growth and satisfaction”, there was an increase in mean points from 6 to 12 months after birth, but not between 8 weeks after discharge and 12 months after birth. The findings also showed that partial and no breastfeeding, higher parental stress, and infant gestational age < 32 weeks were associated with decreased breastfeeding satisfaction. Older maternal age and greater maternal attachment were associated with increased maternal breastfeeding satisfaction. There were no associations between maternal breastfeeding satisfaction and maternal educational level, parity, multiple birth, or maternal birth country other than Sweden, during the first 12 months after birth.

Conclusions

Breastfeeding satisfaction was clearly associated with breastfeeding duration during the first year after birth. Breastfeeding satisfaction may be important to take into account when supporting breastfeeding and when designing interventions to support breastfeeding. Furthermore, these findings highlight the complexity of breastfeeding and emphasize the need for early and good support during neonatal care, so that mothers feel trust in themselves and their infant and in exclusive breastfeeding at discharge and in the first months thereafter.

Trial registration

The randomized controlled trial was registered NCT01806480 with www.clinicaltrials.gov on 2013-03-07.

Research Trends of Follow-Up Care after Neonatal Intensive Care Unit Graduation for Children Born Preterm: A Scoping Review

The purpose of this study was to describe the trends of research on follow-up care after neonatal intensive care unit (NICU) graduation for children born preterm. This scoping review was conducted according to Arksey and O'Malley's guidelines. Reviewed studies were searched in PubMed, CHINAHL, and Web of Science. Fifteen studies were analyzed according to general characteristics, elements of follow-up care after NICU graduation, and characteristics of follow-up care intervention after NICU graduation. Most research was conducted in the medical field (60%), with experimental studies (40%) being the majority, and a few studies focused on families (3%) and parents (3%). The major follow-up care after NICU graduation elements were growth/developmental monitoring and support, continuity of care, parent- and family-centered elements, and a multidisciplinary approach. The intervention methods included home visits, phone calls, video calls, and applications. In addition, the intervention period ranged from two weeks to three years. It is suggested that multidisciplinary research with interactive media for a various age of children over longer periods for further study.

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.

Breastfeeding for 3 Months or Longer but Not Probiotics Is Associated with Reduced Risk for Inattention/Hyperactivity and Conduct Problems in Very-Low-Birth-Weight Children at Early Primary School Age

(1) Background: We aimed to evaluate the effect of proposed “microbiome-stabilising interventions”, i.e., breastfeeding for ≥3 months and prophylactic use of Lactobacillus acidophilus/ Bifidobacterium infantis probiotics on neurocognitive and behavioral outcomes of very-low-birthweight (VLBW) children aged 5–6 years. (2) Methods: We performed a 5-year-follow-up assessment including a strength and difficulties questionnaire (SDQ) and an intelligence quotient (IQ) assessment using the Wechsler Preschool and Primary Scale of Intelligence (WPPSI)-III test in preterm children previously enrolled in the German Neonatal Network (GNN). The analysis was restricted to children exposed to antenatal corticosteroids and postnatal antibiotics. (3) Results: 2467 primary school-aged children fulfilled the inclusion criteria. In multivariable linear regression models breastfeeding ≥3 months was associated with lower conduct disorders (B (95% confidence intervals (CI)): −0.25 (−0.47 to −0.03)) and inattention/hyperactivity (−0.46 (−0.81 to −0.10)) as measured by SDQ. Probiotic treatment during the neonatal period had no effect on SDQ scores or intelligence. (4) Conclusions: Prolonged breastfeeding of highly vulnerable infants may promote their mental health later in childhood, particularly by reducing risk for inattention/hyperactivity and conduct disorders. Future studies need to disentangle the underlying mechanisms during a critical time frame of development.

Psychometric properties of the modified breastfeeding self-efficacy scale-short form (BSES-SF) among Chinese mothers of preterm infants

OBJECTIVE

Preterm mother-infant dyads face more challenges than healthy term infants in breastfeeding initiation and continuation due to maternal health status, preterm infant's immaturity or comorbidities, and breastfeeding policy of the neonatal units. Breastfeeding self-efficacy affects breastfeeding outcomes in preterm infants. No specific instrument in Chinese is available to assess maternal breastfeeding self-efficacy of preterm infants. This study aims to assess the psychometric characteristics of the modified Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) among Chinese mothers of preterm infants.

DESIGN

A cross-sectional study was conducted.

SETTING

Two tertiary hospitals in China.

PARTICIPANTS

A total of 153 women who gave birth before 37 weeks of gestation.

MEASUREMENTS

The instrument was translated and back translated. The internal consistency reliability was investigated using Cronbach's alpha coefficient. The content validity, construct validity, and criterion validity were conducted to evaluate the validity of the scale. Exploratory factor analysis was used to investigate the factor structure.

FINDINGS

The scale had good reliability with Cronbach´s alpha above the acceptable level of 0.7. The Item-Content Validity Index (I-CVI) ranged from 0.800 to 1.000, and the Scale-Content Validity Index (S-CVI) is 0.950. The principal component analysis revealed the presence of two factors with eigenvalues greater than 1, explaining a total variance of 74.665%. The modified BSES-SF scores were correlated with women's parity, breastfeeding knowledge, previous breastfeeding experience, perceived support from the spouse and health professionals, and amounts of expressed milk.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

The Chinese version of modified BSES-SF is a reliable, valid screening instrument to evaluate the maternal breastfeeding self-efficacy of preterm infants. It is recommended to provide interactive, face-to-face breasting education and support to help mothers of preterm infants maintain high level of breastfeeding self-efficacy and further to achieve satisfactory breastfeeding outcomes.

Assessing Swallowing of the Breastfeeding NICU Infant Using Fiberoptic Endoscopic Evaluation of Swallowing: A Feasibility Study

BACKGROUND

Premature infants may demonstrate feeding difficulties requiring an instrumental swallowing assessment. Fiberoptic endoscopic evaluation of swallowing (FEES) is one assessment that can evaluate bottle feeding and breastfeeding.

PURPOSE

This pilot study investigated the safety and feasibility of FEES for neonatal intensive care unit (NICU) infants during breastfeeding.

METHODS

The setting for this prospective, descriptive study was an urban level III NICU that provided care for premature and critically ill infants. Participants were 5 infants recruited from a convenience sample who were at least 37 weeks postmenstrual age, demonstrated feeding difficulties during a bedside feeding and swallowing examination, and were breastfeeding. Each participant received a FEES assessment while breastfeeding (FEES-B). Adverse events and vital signs including prefeeding and postfeeding respiratory rate, heart rate, and oxygen saturation level were recorded to assess safety. Visualization of milk, laryngeal penetration, and tracheal aspiration assessed feasibility.

RESULTS

Participants had a mean postmenstrual age of 39.8 weeks. No adverse events, including epistaxis or laryngospasm, were reported; there were no instances of autonomic instability; and there were no statistically significant differences between prefeeding and postfeeding respiratory rate, heart rate, or oxygen saturation level. Two infants successfully breastfed during FEES-B. Human milk was observable, and laryngeal penetration was noted with 1 infant.

IMPLICATION FOR PRACTICE

FEES-B was found to be safe, with limited data supporting feasibility. Infants demonstrated no physiologic instability during FEES-B, and milk was visualized in the pharynx during breastfeeding with 2 infants.

IMPLICATION FOR RESEARCH

Further studies are warranted to assess effectiveness of FEES-B in infants.

Unpasteurised maternal breast milk is positively associated with growth outcomes in extremely preterm infants

AIM

Extrauterine growth restriction is common among extremely preterm infants. We explored whether intake of unpasteurised maternal milk (MM) and pasteurised donor milk (DM) was associated with longitudinal growth outcomes and neonatal morbidities in extremely preterm infants.

METHODS

Observational study of 90 preterm infants born between 2013 and 2015 in Gothenburg, Sweden. Data were prospectively collected on nutritional and breast milk intakes during the first 28 days.

RESULTS

Ninety infants (39 girls and 51 boys) with a median gestational age of 25.3 (22.7-27.9) weeks were evaluated. MM intake (mL/kg/d) correlated positively with almost all z-scores for weight, length and head circumference at 28 postnatal days and at postmenstrual age (PMA) 32 and 36 weeks. After multivariable adjustment, MM intake and weight z-score at 28 postnatal days and at PMA 32 and 36 weeks remained significantly associated. Infants consuming ≥80% MM had more favourable weight z-scores at PMA 32 and 36 weeks. Intake of DM did not correlate with any growth outcomes. Infants without retinopathy of prematurity had a significantly higher intake of MM (mL/kg/d).

CONCLUSION

Unpasteurised MM was positively associated with longitudinal growth outcomes. Motivating mothers to provide their infants with their own milk after preterm birth should be emphasised.

Cessation of breastfeeding in mothers of preterm infants-A mixed method study

INTRODUCTION

Many women cease breastfeeding earlier than desired. This study examined the cessation of breastfeeding among mothers of preterm infants. Thus, the aim was to describe the cessation of breastfeeding in mothers of preterm infants up to 12 months after birth.

METHOD

This mixed methods study used a convergent design with both qualitative data, consisting of written comments, and quantitative data, on breastfeeding status and breastfeeding satisfaction. The data were collected from questionnaires sent to the mothers at three points during the first year after birth. In total, 270 mothers of preterm infants who breastfed at the time of discharge from the neonatal unit provided data for the study. The quantitative and qualitative data were analysed separately with statistical tests and hermeneutical analysis, respectively and then together according to the convergent mixed methods design.

RESULTS

Four themes of the meanings of the cessation of breastfeeding were identified in the qualitative analysis: "Desire to regain the mother's and the infant's well-being", "The mothers interpretation that the infants actively ceased breastfeeding", "The mother's body and/or the infants' signals showing the way" and "The mother's own will and perceived external obstacles". Mothers who did not breastfeed as long as they wanted were more likely to report less satisfaction with breastfeeding, a shorter breastfeeding period, and less activity when ceasing breastfeeding. In comparison, mothers who breastfed as long as they wanted were more satisfied with breastfeeding, breastfed for a longer period of time and were more active in decision making in breastfeeding cessation.

CONCLUSION

Maternal passivity or activity influenced the cessation of breastfeeding in mothers of preterm infants who breastfed at the time of discharge from the neonatal unit. Passive behaviour related to breastfeeding may result in early cessation of breastfeeding, and low breastfeeding satisfaction while active behaviour may increase breastfeeding length and satisfaction.

Feeding the preterm infant: an overview of the evidence

Feeding from own mother's milk is not always an option for preterm infants, and choosing between alternative means of feeding should be made in light of their effect on infants' health. In this work, we aimed to present evidence regarding feeding pre-term infants with human milk, either own mother's or donor milk (DM), and the potential effects on growth and other health related outcomes. Exclusive breastfeeding (BF) remains the optimal option, whereas feeding with DM as a sole diet or supplemental to maternal milk confers immunological advantages and fewer rates of necrotising enterocolitis against preterm formula feeding, yet the latter results in greater growth velocity. Literature gaps in the use of DM, practical suggestions for choosing suitable feeding means (i.e. continuous support of BF, adequate education regarding feeding preterm infants, including DM), and future perspectives on the potential effects of dietary manipulations of the maternal diet, are also discussed.

Mothers' Adaptation to a Late Preterm Infant When Breastfeeding

The aim of this study was to psychometrically test the Adaptation to the Late Preterm Infant when Breastfeeding Scale (ALPIBS) and also to test how a mother's self-efficacy predicts adaptation to a late preterm infant when breastfeeding. This study had a longitudinal and prospective design, and data collection was consecutive. Mothers (n = 105) with infants born between 340/7 and 366/7 weeks were recruited from a neonatal intensive care unit or a maternity unit. The ALPIBS was developed using exploratory factor analysis, and the association between breastfeeding self-efficacy and ALPIBS score was examined using linear regression analysis. The Breastfeeding Self-Efficacy Scale-Short Form instrument was used to measure self-efficacy in breastfeeding. A higher degree of self-efficacy was significantly associated with a higher degree of adaptation to the late preterm infant's breastfeeding behavior (P < .001). We identified 4 separate underlying factors measured by 11 items in the ALPIBS: (A) breastfeeding is a stressful event; (B) the infant should breastfeed as often as he or she wants; (C) a mother has to breastfeed to be a good mother; and (D) it is important to ensure control over the infant's feeding behavior. There is a link between self-efficacy and ALPIBS score, and self-efficacy is a modifiable factor that influences breastfeeding.

Breastfeeding Disparities between Multiples and Singletons by NICU Discharge

Multiple pregnancy increases the risk of a range of adverse perinatal outcomes, including breastfeeding failure. However, studies on predictive factors of breastfeeding duration in preterm twin infants have a conflicting result. The purpose of this observational study was to compare feeding practices, at hospital discharge, of twin and singleton very low birth weight infants. The study is part of a prospective survey of a national Spanish cohort of very low birth weight infants (SEN1500) that includes 62 neonatal units. The study population comprised all infants registered in the network from 2002 to 2013. They were grouped into singletons and multiples. The explanatory variables were first analyzed using univariate models; subsequently, significant variables were analyzed simultaneously in a multiple stepwise backward model. During the twelve-year period, 32,770 very low birth weight infants were included in the database, of which 26.957 were discharged alive and included in this analysis. Nine thousand seven hundred and fifty-eight neonates were multiples, and 17,199 were singletons. At discharge, 31% of singleton infants were being exclusively breastfed, 43% were bottle-fed, and 26% were fed a combination of both. In comparison, at discharge, only 24% of multiple infants were exclusively breastfed, 43% were bottle-fed, and 33% were fed a combination of both (p < 0.001). On multivariable analysis, twin pregnancy had a statistically significant, but small effect, on cessation of breastfeeding before discharge (OR 1.10; 95% CI: 1.02, 1.19). Risks of early in-hospital breastfeeding cessation were also independently associated with multiple mother-infant stress factors, such as sepsis, intraventricular hemorrhage, retinopathy, necrotizing enterocolitis, intubation, and use of inotropes. Instead, antibiotic treatment at delivery, In vitro fertilization and prenatal steroids were associated with a decreased risk for shorter in-hospital breastfeeding duration. Multiple pregnancy, even in the absence of pathological conditions associated to very low birth weight twin infants, may be an impeding factor for in-hospital breastfeeding.

Review shows that donor milk does not promote the growth and development of preterm infants as well as maternal milk

Aim

This nonsystematic review examined differences in the composition of raw maternal breastmilk and pasteurised donor milk and possible health effects on preterm infants.

Methods

We searched PubMed up to July 2018 for studies published in English that focused on four comparisons as follows: raw maternal milk versus donor milk, human milk before and after Holder pasteurisation, milk from mothers who delivered preterm and at term and milk collected during early and late lactation. We also searched for possible effects of the milk components, as well as the effects of maternal and donor milk on preterm infants’ health.

Results

Raw maternal milk contained factors involved in antioxidant and anti‐inflammatory defence, gut microbiome establishment and the maturation of immune defences, food tolerability and metabolism. Many of these factors were reduced or abolished in processed donor milk. Both maternal milk and donor milk have been associated with a reduced incidence of necrotising enterocolitis. High‐dose feeding with maternal milk during the neonatal period reportedly reduced the risk of other morbidities and promoted growth and neurodevelopment.

Conclusion

Many of the components in raw maternal breastmilk were lacking in pasteurised donor milk, which was inferior in promoting the growth and development of very preterm infants.

Factors Affecting Breastfeeding Outcomes at Six Months in Preterm Infants

BACKGROUND:

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

RESEARCH AIM:

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

METHODS:

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

RESULTS:

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

CONCLUSION:

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

Growth and breastfeeding of preterm infants receiving neonatal tele-homecare compared to hospital-based care

OBJECTIVE

Neonatal tele-homecare implies that parents of clinically stable preterm infants can manage tube feeding and establishment of oral feeding in the home. Support is provided from the neonatal intensive care unit (NICU) through a telehealth service. The aim of this study was to compare growth and breastfeeding rates amongst infants being managed in the NICU (conventional care) and by neonatal tele-homecare.

METHODS

A total of 96 preterm infants with tube feeding requirements participated in the observational study of neonatal tele-homecare. Retrospective data in 278 preterm infants receiving standard care in the same neonatal intensive care unit prior to implementation of neonatal tele-homecare were used for comparison. Rates of breastfeeding and growth were monitored during neonatal tele-homecare. Infant weights were converted to standard deviation weight-for-age z-scores based on a reference.

RESULTS

There was no significant difference in rates of exclusive breastfeeding between the neonatal tele-homecare infants and the controls. Among the very preterm singleton infants more neonatal tele-homecare infants were exclusively breastfed at discharge compared to the controls (p = 0.04). There was no significant difference in median weight for age z-scores at discharge.

CONCLUSION

This study demonstrates that neonatal tele-homecare may be an appropriate model of care for the management of preterm infants outside of the hospital environment; with the added benefit of higher rates of breastfeeding at time of discharge for very preterm infants.

Breastfeeding and risk for ceasing in mothers of preterm infants-Long-term follow-up

Breastfeeding is challenging for mothers of preterm infants. The aim of this paper is to describe risk factors for ceasing breastfeeding and methods of feeding until 12 months postnatal age in mothers who breastfed their preterm infants at discharge from neonatal intensive care units (NICUs). The data come from a randomised controlled trial, which evaluated the effectiveness on exclusive breastfeeding at 8 weeks of proactive telephone support compared with reactive support offered to mothers of preterm infants following discharge from NICU. Six NICUs across Sweden randomised a total of 493 mothers. We used regression and survival analyses to assess the risk factors for ceasing breastfeeding and the long‐term outcomes of the intervention. The results showed that 305 (64%) of the infants were breastfed at 6 months and 49 (21%) at 12 months. Partial breastfeeding at discharge, low maternal educational level, and longer length of stay in the NICU increased the risk for ceasing breastfeeding during the first 12 months. Furthermore, the Kaplan–Meier analysis showed that the proportion of mothers who ceased breastfeeding did not differ between the intervention (n = 231) and controls (n = 262) during the first 12 months (log‐rank test p = .68). No difference was found between groups on method of feeding. More than 85% of the infants were fed directly at the breast. These findings provide important insights for health professionals who are supporting mothers of preterm infants to breastfeed long term. Registered in http://www.clinicaltrials.gov (NCT01806480).

Prevalence and duration of breast milk feeding in very preterm infants: A 3-year follow-up study and a systematic literature review

BACKGROUND

The World Health Organization recommends exclusive breast milk feeding until 6 months and continuing up to 2 years of age; little is known about whether very preterm infants are fed in accordance with these recommendations. We aimed to describe the prevalence and duration of breast milk feeding in very preterm children and to systematically review internationally published data.

METHODS

We evaluated breast milk feeding initiation and duration in very preterm children born in 2 Portuguese regions (2011-2012) enrolled in the EPICE cohort and followed-up to the age of 3 (n = 466). We searched PubMed^® from inception to January 2017 to identify original studies reporting the prevalence and/or duration of breast milk feeding in very preterm children.

RESULTS

91.0% of children received some breast milk feeding and 65.3% were exclusively breast fed with a median duration of 2 months for exclusive and 3 months for any breast milk; only 9.9% received exclusive breast milk for at least 6 months, 10.2% received any breast milk for 12 months or more, and 2.0% for up to 24 months. The literature review identified few studies on feeding after hospital discharge (n = 9); these also reported a low prevalence of exclusive breast milk feeding at 6 months (1.0% to 27.0%) and of any breast milk at 12 months (8.0% to 12.0%).

CONCLUSIONS

The duration of breast milk feeding among Portuguese very preterm infants was shorter than recommended. However, this appears to be common globally. Research is needed to inform strategies to promote continued breast milk feeding.

Proactive telephone support provided to breastfeeding mothers of preterm infants after discharge: a randomised controlled trial

Aim

The aim was to evaluate the effectiveness of proactive telephone support provided to breastfeeding mothers of preterm infants after discharge from neonatal intensive care units (NICU).

Methods

Between March 2013 and December 2015, a randomised controlled trial was conducted at six NICUs across Sweden. At each NICU, a breastfeeding support team recruited, randomised and delivered the support to participating mothers. The intervention group received a daily proactive telephone call up to 14 days after discharge from the support team. The control group could initiate telephone contact themselves. Primary outcome was exclusive breastfeeding eight weeks after discharge. Secondary outcomes were maternal satisfaction with breastfeeding, attachment, quality of life and parental stress.

Results

In total, 493 mothers were randomised, 231 to intervention group and 262 to control group. There were no differences between the groups for exclusive breastfeeding, odds ratio 0.96, 95% CI 0.66–1.38, nor for maternal satisfaction with breastfeeding, attachment or quality of life. The intervention group reported significantly less parental stress than the controls, t = 2.44, 95% CI 0.03–0.23, effect size d = 0.26.

Conclusion

In this trial, proactive telephone support was not associated with increased exclusive breastfeeding prevalence eight weeks following discharge. However, intervention group mothers showed significantly lower parental stress.
