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

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.

Pressure to provide milk among mothers of very low birth weight infants: an explorative study

BACKGROUND

Pump-dependent mothers of very low birth weight (VLBW, < 1500g) infants experience specific challenges achieving sufficient milk supply in the neonatal intensive care unit (NICU) and are therefore less frequently able to achieve (exclusive) breast milk feeding. Stress due to the limitations on participating in the infant's care may contribute to this problem. Some explorative studies suggest that pressure to provide milk may be an additional stressor in mothers. However, the type of pressure to provide milk perceived by mothers of VLBW infants has rarely been examined.

METHODS

A retrospective and anonymous questionnaire was conducted with mothers of VLBW infants aged 6 to 24 months at the time of data collection. Quantitative data and written comments were used to examine the mothers' perceptions. Descriptive and bivariate tests (Spearman´s rho, Pearson's chi2) were performed to show correlations between pressure to provide breast milk, parental stress (PSS:NICU: role alteration subscale), milk volume, and maternal factors. Pressure to provide milk was measured through two self-developed single items to differentiate between internal and external pressures.

RESULTS

Data of n = 533 mothers of VLBW infants was analysed. More than 70% of the mothers agreed that they pressured themselves to provide milk for their infant. In contrast, 34% of the mothers agreed that they felt pressure from outside to provide milk. Higher milk volume 14 days post-partum was significantly correlated with higher internal (Spearman´s rho = 0.2017, p = 0.000) and higher external pressure to provide milk (Spearman´s rho = 0.2991; p = 0.000). Higher PSS:NICU parental role alteration scores were significantly correlated with more internal (Spearman´s rho = -0.2865, p = 0.000) and more external pressure to provide milk (Spearman´s rho = -0.1478; p = 0.002). Milk volume 14 days post-partum and the PSS:NICU were not significantly correlated (Spearman´s rho = -0.0190; p = 0.701). Qualitative analyses highlighted these results and enhanced the bidirectional relationships between maternal pressure to provide milk and milk volume.

CONCLUSIONS

Especially internal pressure to provide milk is perceived by many mothers, being mutually dependent on milk supply and parental stress. Pressure to provide milk may be an important factor to decrease maternal stress in the NICU and, therefore, lead to more positive pumping and breastfeeding experiences. More research and validated instruments are needed to adequately measure pressure to provide milk with its different psychological, social, and environmental dimensions.

Factors associated with high exclusive breastfeeding rates among preterm infants under 34 weeks of gestation in Da Nang, Vietnam: A retrospective cohort study

Background

Preterm infants have higher mortality than full-term infants. While breastfeeding dramatically reduces preterm death, it is limited by biological and practice barriers, particularly for babies born before 34 weeks gestational age. Da Nang Hospital for Women and Children developed a quality improvement approach to improve breastfeeding of preterm infants by strengthening feeding support, non-separation, and kangaroo mother care (KMC).

Methods

To determine breastfeeding outcomes following discharge and explore factors associated with improved feeding, mothers of infants under 34 weeks gestational age born October 2021 to March 2022 and discharged alive were interviewed at six months and their medical records were reviewed.

Results

Out of 104 preterm infants included, all were exclusively breastfed at discharge and one month, 86.5% at three months, and 63.5% at six months; 47.1% received immediate skin-to-skin contact, 31.7% immediate and continuous KMC, and the remaining 68.3% continuous KMC beginning at a median of three days. Exclusive breastfeeding at six months was associated with the mother antenatally seeking breastfeeding information (odds ratio (OR) = 14.5; 95% confidence interval (CI) = 1.2-173.6), avoiding bottle-feeding at home (OR = 7.7; 95% CI = 1.7-33.7) and reduced with each day delay between birth and full breastfeeding (OR = 0.8; 95% CI = 0.6-0.9).

Conclusions

Hospital environments that limit mother-baby separations and feeding delays, including rooming-in of mothers and infants, KMC, and breastfeeding support from birth, enabled 100% of preterm infants born before 34 weeks gestational age to breastfeed exclusively with continued rates higher than previously reported. Addressing antenatal and post-natal factors limiting practice can further improve longer-term breastfeeding outcomes. The approach can be adapted to achieve high exclusive breastfeeding rates, regardless of gestational age.

Feeding Practices of Preterm Low Birthweight Infants Up to 6 Months: A Comparison Between Kangaroo and Conventional Care

OBJECTIVE

The objective of this study is to compare feeding practices of low birthweight (LBW) infants, according to type of care received during and after hospital discharge: Kangaroo Care (KC) and Conventional Care (CC).

METHODS

Prospective cohort study was conducted at a university hospital (Brazil) between 2019 and 2021. The sample consisted of 65 LBW infants (weight ≤ 1800 g)-46 in KC and 19 in CC. KC includes breastfeeding (BF) guidance and support to parents at hospital and after discharge. Data collection was performed at hospital discharge, and at the 4th and 6th month of corrected gestational age (CGA). Consumption of 27 foods was analyzed in the last 2 periods of the follow-up and expressed in relative frequency. Three indicators were analyzed: exclusive breastfeeding (EBF), mixed BF, and introduction of liquid and solid foods.

RESULTS

Groups had similar health characteristics, except for the weight at hospital discharge and the Score for Neonatal Acute Physiology - Perinatal (SNAPPE II) score that were lower in KC group. We found higher frequency of EBF among KC at hospital discharge (CC = 5.3% vs KC = 47.8%; P = 0.001). The higher frequency of mixed BF was observed in KC at 4 months of CGA (CC = 5.6% vs KC = 35.0%; P = 0.023), and at 6 months of CGA (CC = 0.0% vs KC = 24.4%; P = 0.048). Consumption of solid foods (4th month of CGA = 25.9%, 6th month of CGA = 91.2%) and liquids (4th month of CGA = 77.6%, 6th month of CGA = 89.5%) were similar between groups.

CONCLUSIONS

In KC, SNAPPE II scores were lower and frequency of EBF was higher at hospital discharge and frequency of mixed BF was higher over 6 months. Early supply of infant formula, liquid and solid foods were similar in both groups.

Equally Good Neurological, Growth, and Health Outcomes up to 6 Years of Age in Moderately Preterm Infants Who Received Exclusive vs. Fortified Breast Milk-A Longitudinal Cohort Study

Moderately preterm infants (32-36 weeks of gestational age) have an increased risk of worse health and developmental outcomes compared to infants born at term. Optimal nutrition may alter this risk. The aim of this study was to investigate the neurological, growth, and health outcomes up to six years of age in children born moderately preterm who receive either exclusive or fortified breast milk and/or formula in the neonatal unit. In this longitudinal cohort study, data were collected for 142 children. Data were collected up to six years of age via several questionnaires containing questions about demographics, growth, child health status, health care visits, and the Five to Fifteen Questionnaire. Data on the intake of breast milk, human milk fortification, formula, and growth during hospitalization were collected from the children's medical records. No statistically significant differences in neurological outcomes, growth, or health at six years of age were found between the two groups (exclusive breast milk, n = 43 vs. fortified breast milk and/or formula, n = 99). There is a need for research in larger populations to further assess potential effects on health and developmental outcomes when comparing the use of exclusive versus fortified breast milk for moderately preterm infants during neonatal hospitalization.

Breastfeeding Self-Efficacy, a Predictor of Early Cessation of Exclusive Breastfeeding Among Mothers Giving Birth Preterm

The aim was to describe the prevalence of exclusive breastfeeding among mothers of premature infants and investigate the extent to which breastfeeding self-efficacy is associated with early cessation of exclusive breastfeeding. The study population consisted of 136 mother-infant dyads with information on the outcome of exclusive breastfeeding and exposure of self-efficacy, recruited between September 2016 and February 2018. Data were collected via questionnaires with follow-up at 6 months. The statistical analysis included descriptive analysis with survival curves and logistic regression analysis. At 2 months, 101 (74%) premature infants were exclusively breastfed; at 4 and 6 months, 82 (60%) and 41 (30%), respectively. Higher levels of self-efficacy were significantly associated with breastfeeding exclusively for 2 months (P = .03). In multivariate analysis, mothers who had a low level of early self-efficacy toward breastfeeding had 2½ times higher odds of breastfeeding cessation before 2 months (odds ratio = 2.63, 95% confidence interval: 1.16-5.96). The risk did not change when adjusted for potential confounders. Breastfeeding self-efficacy is an early predictor of exclusive breastfeeding for 2 months of the premature infant. Health professionals should use self-efficacy as a prognostic factor to identify mothers at risk of early cessation of breastfeeding and support those with low self-efficacy to increase duration of exclusive breastfeeding.

Predictive factors of exclusive breastfeeding attrition at Week 6 post-partum among mothers of preterm infants based on the theory of planned behaviour

Breastfeeding plays an important role in the growth and development of preterm infants, and exclusive breastfeeding (EBF) in the first 6 weeks post-partum is the key to continuous breastfeeding. This study was designed to explore the influencing factors that contribute to breastfeeding attrition among mothers of preterm infants at Week 6 post-partum based on the theory of planned behaviour (TPB). We herein adopted a prospective observational study design in which 97 mothers who exclusively breastfed at Week 6 post-partum at a tertiary specialised hospital in Shanghai from June 2021 to February 2022 were taken as the EBF group, and 179 mothers without EBF were assigned to the EBF attrition group. Through an extensive literature review and expert consultation, we determined the possible factors influencing EBF attrition, analysed those factors that showed statistical significance in our univariate analysis by applying binary logistic regression, and constructed a nomogram model for predicting EBF attrition. The results revealed that negative breastfeeding sentiment (odds ratio [OR] = 1.006; 95% confidence interval [CI], 1.000-1.011) generated a greater risk of breastfeeding attrition. However, positive breastfeeding sentiment (OR = 0.991; 95% CI, 0.983-0.999), social and professional support (OR = 0.993; 95% CI, 0.987-0.999), breastfeeding control (OR = 0.945; 95% CI, 0.896-0.996), knowledge (OR = 0.893; 95% CI, 0.799-0.998), and intention to EBF at Week 6 post-partum (OR = 0.522; 95% CI, 0.276-0.988) were the protective factors and facilitated the development of our nomogram model. The Hosmer-Lemeshow goodness-of-fit test generated a χ² value of 11.344 (p = 0.183) and an area under the curve of 0.822 (95% CI, 0.771-0.873). The C-index was 0.800 in the internal bootstrap validation, indicating that the nomogram model possessed favourable predictive accuracy and discrimination.

Perinatal Factors Associated With Breastfeeding Trends After Preterm Birth <29 Weeks Gestation: Can We Predict Early Discontinuation?

OBJECTIVE

To determine the rates and perinatal factors associated with initiation and early discontinuation of breastfeeding among very preterm neonates.

METHODS

This was a retrospective cohort study of very preterm infants (<29 weeks gestation) admitted to 2 regional Level III neonatal intensive care units (NICUs) from January 1, 2015, to December 31, 2019. A national neonatal database was used to evaluate initiation and continuation rates of breastfeeding and associated perinatal factors. Stored nutrition profiles and delivery record books were used to determine feeding volumes associated with continuation of breastfeeding to hospital discharge for a subgroup of infants at a single site. Descriptive and inferential statistics were used to present the results between groups, and logistic regression modeling was used to calculate crude and adjusted odds ratios (OR) and 95% CI.

RESULTS

Of 391 eligible neonates, 84% initiated breastfeeding but only 38% continued to discharge. Interestingly, frequency of breastfeeding initiation (P < 0.001) and continuation (P < 0.001) declined over the study period. After adjustment for confounders, younger maternal age, earlier gestational age, cigarette smoking, and multiparity were significantly associated with early discontinuation of breastfeeding prior to hospital discharge. Early discontinuation of breastfeeding was also related to lower volumes of breastmilk by day 7 of life (P = 0.004).

CONCLUSION

Very preterm neonates are at high risk for non-initiation and early discontinuation of breastfeeding. The early postnatal period represents a critical time to establish breastmilk volumes, and the identification of key perinatal risk factors allows for early and targeted breastfeeding support.

Breastfeeding self-efficacy predicts breastmilk feeding in preterm infants at discharge from the neonatal intensive care unit

AIM

To examine the association between breastfeeding self-efficacy (BSE) and breastmilk feeding at discharge from the neonatal intensive care unit among mothers of preterm infants.

DESIGN

Secondary analysis of the Family Integrated Care (FICare) cluster randomized controlled trial.

METHODS

Data from 221 mothers of preterm infants who participated in the standard care group of the trial were analysed. BSE at admission was assessed using the modified Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF). Breastmilk feeding was assessed using 24 hr maternal recall at discharge.

RESULTS

Mothers who were exclusively breastmilk feeing their infants at discharge had statistically significantly higher mean BSES-SF scores at admission (68.4, SD = 13.7) than those providing a combination of breastmilk and formula or only formula (59.6, SD = 14.7; p < .001). Multivariable logistic regression showed that higher BSE at admission, maternal birth in Canada, and absence of diabetes were statistically significant predictors of exclusive breastmilk feeding at discharge.

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.

Factors Associated with Breastfeeding Initiation and Duration in Greece: Data from the Hellenic National Nutrition and Health Survey

Despite its well-documented benefits, breastfeeding rates and duration worldwide do not meet the recommended goals set by the World Health Organization. Data on infant feeding, socio-demographic, lifestyle and perinatal factors were used from 490 mothers (and 958 children), participants at the Hellenic National Nutrition and Health Survey between 2013−2015. Clustered multiple logistic regression and multilevel mixed-model regression analyses were performed to identify factors associated with breastfeeding initiation and duration, respectively. Maternal lower education [Odds Ratio (OR): 2.29, 95% Confidence intervals (95% CI): 1.30−4.04; p = 0.004], smoking during pregnancy (OR: 3.08, 95% CI: 1.64−5.77; p < 0.001), caesarean section (OR = 3.26, 95% CI: 1.83−5.83; p < 0.001), prematurity (OR = 2.74, 95% CI: 1.40−5.37; p = 0.003) and higher birth order (OR = 1.30, 95% CI: 1.04−1.62; p = 0.020) were associated with increased odds of not initiating breastfeeding. Living in rural areas [beta coefficient b = −27.93, p = 0.043], smoking during pregnancy (b = −64.47, p < 0.001), caesarean section (b = −28.76, p = 0.046) and prematurity (b = −46.67, p = 0.048) were significantly associated with shorter breastfeeding duration. Children born chronologically closer to the survey were more likely to breastfeed and for longer periods. Educational promotion and enhancement of breastfeeding awareness that account for maternal exposures are required. Prevention of prematurity and avoidance of unnecessary caesarean section is crucial, while additional breastfeeding support is needed when preterm birth occurs, or caesarean section cannot be avoided.

Saudi Hospitals Compliance With the (Baby-Friendly Hospitals Initiative) Evaluation Study

Introduction

National surveys from Saudi Arabia have shown that the breastfeeding rate in Saudi Arabia is lagging behind the global recommendations. The UNICEF and WHO have launched the 10-step Baby-Friendly Hospital Initiative (BFHI) for encouraging healthcare facilities across the world to support breastfeeding in a better way. In this study, we validated the Arabic version of the self-appraisal and monitoring tool based on the BFHI as well as assessed the determinants of breastfeeding practice in Saudi Arabia.

Methods

This was an analytical cross-sectional study. We used the free validated tool-Questionnaire for Breastfeeding Mother based on the BFHI Session 4.2 Guidelines. The tool was translated and validated in Arabic. A nonprobability sample included mothers of children based on the following inclusion criteria: 1) mothers living in Saudi Arabia; 2) mothers of children aged 0-12 months. The Arabic version was modified into six parts, and the questionnaire was left open for respondents for a period of six months. Descriptive statistics were performed using the Statistical Package for the Social Sciences, version 21 (IBM Corp., Armonk, NY).

Results

The sample size was 584, and during prenatal visits, 23.6% of mothers were provided with information about skin-to-skin contact immediately after childbirth. Of these, 40% started breastfeeding immediately and 43% were encouraged to breastfeed postnatally. On discharge, 34.6% of mothers received help for feeding-related issues.

Conclusion

Our hospitals are well set to adopt the BFHI in terms of policy making and coordinated postnatal care. However, prenatal care should be more focused on promoting breastfeeding. Massive and coordinated quality improvement steps are highly indicated to completely implement the initiative.

Antenatal breastfeeding promotion amongst pregnancies at high-risk for newborn admission to the NICU: A cross-sectional study

Objectives

To determine the prevalence and factors associated with antenatal promotion of breastfeeding in high-risk pregnancies.

Study design

This was a cross-sectional study of trends in breastfeeding promotion during antenatal consultation of pregnancies at high-risk for newborn admission to the neonatal intensive care unit (NICU) between January 2017 and December 2020. Eligible high-risk pregnant patients undergoing antenatal consultation in a tertiary-level fetal assessment unit were identified using an electronic clinic repository. Consult letters and fetal assessment reports were reviewed to determine baseline demographics, pregnancy history, fetal findings, and communication about breastfeeding. Descriptive and inferential statistics were used to present findings and compare outcomes between groups.

Results

316 pregnancies were included for final analysis. The mean maternal age was 28.7 years (SD 6.2) and 65 % were multiparas. Median gestational age at time of antenatal consult was 32 weeks [IQR 29–34]. The main indication for consultation was fetal anomalies (72.8%), namely cardiac defects (21.2 %). There was a significant improvement in prevalence of antenatal discussions about breastfeeding over the study period, from 48.8 % early in the study period compared to 73.7 % in the past year (p = 0.036). However, amongst consults where breastfeeding was discussed, almost one-quarter (23.8 %) of patients indicated that they were not planning on breastfeeding postnatally.

Conclusion

There has been a significant improvement in promoting breastfeeding antenatally amongst high-risk pregnancies. However, no follow-up or supports were offered to one-quarter of patients who indicated no intention of breastfeeding or using donor milk postnatally. Ongoing work is required to further advance breastfeeding promotion antenatally, increase parental supports and education, and optimize breastfeeding rates postnatally for improving outcomes of this high-risk group.

•

While there has been a significant improvement in antenatal breastfeeding promotion amongst high-risk pregnancies, it is still missing in almost one-quarter of patients.

•

There are no obvious demographic or clinical differences between high-risk patients that received antenatal breastfeeding promotion versus those that did not, suggesting that a more standardized approach to antenatal discussions about infant feeding could improve breastfeeding success in the NICU.

•

Ongoing work is required to further improve breastfeeding promotion antenatally along with additional postnatal supports to enhance breastfeeding success.

Redesigning care to support earlier discharge from a neonatal intensive care unit: a design thinking informed pilot

Background

Preterm infants may remain in neonatal intensive care units (NICUs) to receive proper nutrition via nasogastric tube feedings. However, prolonged NICU stays can have negative effects for the patient, the family and the health system.

Aim

To demonstrate how a patient-centred, design thinking informed approach supported the development of a pilot programme to enable earlier discharge of preterm babies.

Method

We report on our design thinking-empathy building approach to programme design, initial outcomes and considerations for ongoing study.

Results

Through the use of design thinking methods, we identified unique needs, preferences and concerns that guided the development of our novel early discharge programme. We found that stable, preterm infants unable to feed by mouth and requiring nasogastric tubes can be cared for at home with remote patient monitoring and telehealth support. In addition, novel feeding strategies can help address parental preferences without compromising infant growth.

Conclusion

A patient-centred, design thinking informed approach supported the development of a pilot programme to enable earlier discharge of preterm babies. The programme resulted in a reduced length of stay, thereby increasing NICU bed capacity and limiting hospital turn-aways.

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.

Remote provision of breastfeeding support and education: Systematic review and meta-analysis

The Covid‐19 pandemic has led to a substantial increase in remotely provided maternity care services, including breastfeeding support. It is, therefore, important to understand whether breastfeeding support provided remotely is an effective method of support. To determine if breastfeeding support provided remotely is an effective method of support. A systematic review and meta‐analysis were conducted. Twenty‐nine studies were included in the review and 26 contributed data to the meta‐analysis. Remotely provided breastfeeding support significantly reduced the risk of women stopping exclusive breastfeeding at 3 months by 25% (risk ratio [RR]: 0.75, 95% confidence interval [CI]: 0.63, 0.90). There was no significant difference in the number of women stopping any breastfeeding at 4–8 weeks (RR: 1.10, 95% CI: 0.74, 1.64), 3 months (RR: 0.89, 95% CI: 0.71, 1.11), or 6 months (RR: 0.91, 95% CI: 0.81, 1.03) or the number of women stopping exclusive breastfeeding at 4–8 weeks (RR: 0.86, 95% CI: 0.70, 1.07) or 6 months (RR: 0.93, 95% CI: 0.85, 1.0). There was substantial heterogeneity of interventions in terms of mode of delivery, intensity, and providers. This demonstrates that remote interventions can be effective for improving exclusive breastfeeding at 3 months but the certainty of the evidence is low. Improvements in exclusive breastfeeding at 4–8 weeks and 6 months were only found when studies at high risk of bias were excluded. They are also less likely to be effective for improving any breastfeeding. Remote provision of breastfeeding support and education could be provided when it is not possible to provide face‐to‐face care.

•

This systematic review investigated the effectiveness of breastfeeding support interventions provided remotely.

•

There was significant heterogeneity in how support interventions and standard care were provided.

•

There is low‐quality evidence that remotely provided breastfeeding support significantly reduced the risk of women stopping exclusive breastfeeding at 3 months but not at 4‐8 weeks or 6 months. There was no significant difference in the number of women stopping any breastfeeding.

•

Interventions tended to demonstrate more positive effects when standard care was limited suggesting remote support is preferable to no support.

•

There was a lack of evidence exploring women's satisfaction and the impact on maternal mental health. More research is needed to explore this.

Eating Behaviors, Caregiver Feeding Interactions, and Dietary Patterns of Children Born Preterm: A Systematic Review and Meta-Analysis

Infants born preterm (<37 weeks of gestation) often experience feeding problems during hospitalization. Whether difficulties persist or have long-term sequelae on childhood eating is unclear. We aimed to describe the oromotor eating skills (e.g., chewing/swallowing), eating behaviors (e.g., food neophobia), food parenting practices (e.g., pressure to eat), and dietary patterns of preterm children during late infancy (6-12 mo) and early childhood (>12 mo-7 y) and to determine whether these differed from those of term-born peers. We identified 67 articles (57 unique studies) for inclusion. We used random-effects meta-analysis of proportions to examine the prevalence of oromotor eating skill and eating behavior challenges among preterm children, standard meta-analysis for comparisons with term-born peers, and the Grading of Recommendations, Assessment, Development and Evaluation approach to assess the certainty of evidence. Forty-three percent (95% CI: 24%, 62%) of infants and 25% (95% CI: 17%, 33%) of children born preterm experienced oromotor eating difficulties and 16% (95% CI: 4%, 27%) and 20% (95% CI: 11%, 28%), respectively, exhibited challenging eating behaviors. During late infancy and early childhood, oromotor eating difficulties (OR: 2.86; 95% CI: 1.71, 4.77; I2 = 67.8%) and challenging eating behaviors (OR: 1.52; 95% CI: 1.11, 2.10; I2 = 0.0%) were more common in those born preterm than in those born term: however, the certainty of evidence was very low. Owing to the low number and heterogeneity of studies, we narratively reviewed literature on food parenting and dietary patterns. Mothers of preterm infants appeared to have heightened anxiety while feeding and utilized coercive food parenting practices; their infants reportedly received less human milk, started solid foods earlier, and had poorer diet quality than term-born peers. In conclusion, meta-analyses show preterm children experience frequent oromotor eating difficulties and challenging eating behaviors throughout the early years. Given preterm birth increases risk of later obesity and diet-related chronic disease, research examining the effects of caregiver-child interactions on subsequent diet is warranted.

A prospective cohort study on lactation status and breastfeeding challenges in mothers giving birth to preterm infants

Background

Mothers of preterm infants face many challenges in breastfeeding, especially regarding lactation. This study aimed to investigate the lactation status and challenges in breastfeeding faced by preterm infants’ mothers.

Methods

We approached 124 mothers who gave birth to preterm infants between 26 May and 31 October 2018 in a tertiary hospital in China. Lactation status and challenges in breastfeeding on day 7 postpartum, at discharge of infants, 2 weeks post-discharge, and 3 months of corrected age were collected using questionnaires. The area under the receiver operating characteristic (ROC) curve for expressed milk volume on day 7 postpartum for predicting expressed milk volume ≥ 300 mL/d at discharge was calculated. Logistic regression analyses were performed to identify factors associated with delayed lactogenesis II onset and continuation of breastfeeding at 3 months of corrected age.

Results

Seventy mothers were enrolled, and 51.4% had delayed lactogenesis II. Multivariate logistic regression analysis revealed that older maternal age (aOR = 1.19; 95% CI: 1.01, 1.40) and first live birth (aOR = 4.81; 95% CI 1.43, 16.18) were significant independent predictors of delayed lactogenesis II. Mothers with delayed lactogenesis II had significantly lower expressed milk volume (day 7 postpartum: 160.0 mL vs. 300.0 mL, U = 328.50, p = 0.001; at discharge: 425.0 mL vs. 612.5 mL, U = 372.00, p = 0.005), with a lower proportion of exclusive breastfeeding in their infants (at discharge: 33.3% vs. 69.8%, χ² = 12.39, df = 1, p < 0.001; 3 months of corrected age: 17.8% vs. 52.8%, χ² = 11.03, df = 1, p = 0.001). The ROC showed that expressed milk volume > 190 mL/d on day 7 postpartum significantly predicted expressed milk volume ≥ 300 mL/d at discharge. Insufficient human milk was the main reason for breastfeeding discontinuation at 3 months of corrected age. Twins were less likely to continue breastfeeding at 3 months of corrected age (aOR = 0.27; 95% CI 0.09, 0.86). In singleton infants, mother’s own milk ≥50% of total milk uptake at 2 weeks post-discharge (aOR = 32.66; 95% CI 3.00, 355.25) was an independent predictor of continuous breastfeeding at 3 months of corrected age. Feeding complications in infants, poor breastfeeding technique, and low milk output are the main challenges in breastfeeding.

Conclusion

Interventions to improve early postpartum lactation and breastfeeding techniques may increase breastfeeding adoption in mothers of preterm infants.

Human milk microbes: Strategies to improve delivery to the infant

Mother's own milk provides personalized nutrition and immune protection to the developing infant. The presence of healthy microbes plays an important role in the infant's gut by programming the microbiota and excluding potential pathogens. This review describes the important components in mother's own milk that contribute to its superiority for infant nutrition and suggest potential strategies to replicate these factors in alternative feedings when sufficient milk is unavailable. Current strategies to supplement, substitute and replicate mother's own milk including microbial restoration, use of unpasteurized donor human milk, probiotics and fortification are discussed. Critical work remains to be done in understanding the human milk microbiome and metabolome and in improving lactation support for mothers of preterm infants. Increasing delivery of mother's own milk and milk components to infants would likely positively impact infant mortality and health worldwide.

Influence of patterns of neonatal transfers on breastfeeding outcomes

AIM

To investigate/evaluate the impact of hospital transfers on breastfeeding outcomes for infants requiring neonatal intensive care and to explore approaches to supporting lactation and breastfeeding.

METHODS

A national study of two cohorts of infants admitted to the nine neonatal intensive care units (NICUs) in New South Wales (NSW) Australia using data sourced from a prospectively collected NICUS data collection.

RESULTS

A total of 7829 infants were admitted to the nine NICUs in NSW for two 18-month cohorts (2012/2013 and 2015/2016) and were included in the study. These infants experienced 17 238 transfers to 107 different hospitals during the study period. Multiple transfers and low gestational age were independently associated with lower breastfeeding rates at hospital discharge across both cohorts. Extremely preterm infants and those with the greatest number of hospital transfers are least likely to be breastfed at time of discharge. Breastfeeding rates remained unchanged over time. The level of lactation support varied across NICUs.

CONCLUSION

This study highlights the challenges of establishing and maintaining breastfeeding for infants requiring intensive care who have had multiple hospital transfers for continuing or specialist care. There is wide variation in lactation support across facilities. The importance of a consistent approach, education programmes and the provision of appropriate lactation support is emphasised.

Privacy, Early Colostrum, and Gestational Age are Associated with Exclusive Breastfeeding in Preterm and Sick Term Infants

Our study was designed to assess the rates of exclusive breastfeeding (defined as direct breastfeeding) and the use of mother's own milk (MOM) in preterm infants and sick term infants at discharge and to identify potential influencing factors such as gestational age, early colostrum, and privacy. The study was conducted at a German level III neonatal department. All preterm and sick term infants admitted to the neonatal intensive care unit, the pediatric intensive care unit, the intermediate care unit, and the low care ward were included in the study. Infants were recruited between March and October 2015 (phase 1) and April to July 2016 (phase 2). Due to an emergency evacuation, privacy was limited during the first phase. Breastfeeding and the use of MOM were assessed daily using a self-designed score. In total, 482 infants of 452 mothers were included. More than 90% initiated breastfeeding and one-third were exclusively breastfed at discharge. Extremely immature infants and late preterm infants were less likely to be exclusively breastfed at discharge. Privacy (p<0.001) and early colostrum (p=0.002) significantly increased exclusive breastfeeding. Conclusion Extremely immature and late preterm infants were least likely to be exclusively breastfed at discharge and need special support. Interventions such as privacy and early colostrum should be promoted to increase breastfeeding.

Demographic, Social, and Personal Factors Associated With Lactation Cessation by 6 Weeks in Mothers of Very Low Birth Weight Infants

BACKGROUND

Although mother's own milk decreases prematurity-associated morbidities, mothers of infants born preterm and very low birth weight experience a significantly shorter lactation duration. Little is known regarding factors associated with lactation cessation during the hospitalization of a very low birth weight infant.

RESEARCH AIM

To determine demographic, social, and personal factors associated with lactation cessation by 6-weeks postpartum in mothers delivering very low birth weight infants.

METHODS

We used a retrospective, longitudinal, two-group comparison design using data from a randomized control study. Mothers of very low birth weight infants (N = 142) were enrolled from a labor and delivery unit associated with a Level 4 neonatal intensive care unit. Demographic, social, and health information was obtained from the medical records. Participants were surveyed regarding lactation goals, experience, and reason(s) for cessation.

RESULTS

Participants who did not continue lactating for more than 6 weeks were more likely to be unemployed (p = .019), Medicaid eligible (p = .009), less educated (p < .031), smoke (p = .002), provide less skin-to-skin care (p = .007), and to delay the decision to provide their milk to their infant (p = .007). After Bonferroni adjustment, only minutes of skin-to-skin care remained statistically significant. Insufficient maternal milk production was the most common reason for lactation cessation.

CONCLUSION

While the etiology of lactation cessation is often non-modifiable, strategies aimed at maintaining mother's own milk production, smoking cessation, increasing skin-to-skin care, and promoting an earlier decision to lactate, may prolong lactation duration in this vulnerable population.This RCT was registered (2012-00071) with ClinicalTrials.com on 6/28/2013.

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.

Parity and the Association Between Maternal Sociodemographic Characteristics and Breastfeeding

Objective: Although clinicians recognize the importance of breastfeeding for child health, breastfeeding initiation can be limited by maternal characteristics such as race/ethnicity, age at first birth, and educational attainment. We hypothesized that the strong influence of prior infant feeding experiences on multiparous women's decision to initiate and continue breastfeeding may mean that these maternal characteristics influence breastfeeding more strongly for primiparas than multiparas. Materials and Methods: Using Pregnancy Risk Assessment and Monitoring System (PRAMS) (Phase 8) survey data from 2016 to 2017, we analyzed mothers' responses to the supplemental question about parity, "Before you got pregnant with your new baby, did you ever have any other babies who were born alive?" Study variables were summarized by using weighted means and proportions and compared according to parity by using Wald tests. In the overall cohort, we evaluated the interaction between parity and each covariate by using logistic regression. Results: In our sample (N = 20,694), 40% of respondents were first-time mothers, and 88% had initiated breastfeeding. Primiparas were more likely to breastfeed than multiparas (92% versus 86%; p < 0.001), but they had shorter mean breastfeeding duration. On unadjusted analysis, four covariates were more strongly associated with breastfeeding initiation among primiparas than multiparas (maternal age, educational attainment, receiving breastfeeding information from a nurse or other medical professional, and receiving breastfeeding information from family or friends). Conclusions: Breastfeeding initiation is impacted more strongly by maternal characteristics for primiparas than multiparas.

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.

Comparison of video and in-hospital consultations during early in-home care for premature infants and their families: A randomised trial

Introduction

Early in-home care is increasingly being used in Scandinavian countries for clinically stable premature infants. Due to challenges with travel and hospital resources, alternative ways to support parents during early in-home care are being considered. The aim of this study was to test whether the proportion of mothers exclusively breastfeeding, parental confidence and mother–infant interaction increased after early in-home care with premature infants, and to compare the outcomes of in-home care involving the use of video communication and a mobile application with those of in-home care involving in-hospital consultations.

Methods

This study was conducted in four neonatal wards offering premature infant in-home care in Denmark. Premature infants were randomised using 1:1 block randomisation. During early in-home care, families had planned consultations two to three times a week, during which they received support from nurses: the intervention group had video consultations, while the control group had in-hospital consultations.

Results

The proportion of exclusively breastfeeding mothers at discharge was 66.7% in the intervention group vs 66% in the control group and decreased to 49.4% vs 55%, respectively, 1 month after discharge. No significant improvements were found in the intervention group compared with the control group. In the intervention group, some video consultations were changed to telephone consultations due to problems with the video function, or to in-hospital consultations due to infants’ requirement for medical services. No significant differences in secondary outcomes were observed.

Discussion

The study showed similar breastfeeding proportions at discharge. No unfavourable effects of video consultation compared with in-hospital consultation were found, indicating that video consultation could be a viable option and an important supplement during early in-home care.

Effect of vacuum-release teat versus standard teat use on feeding milestones and breastfeeding outcomes in very preterm infants: A randomized controlled trial

Background

Breast milk is important to infant health, yet shorter breastfeeding duration is reported for preterm infants. Both breast and bottle feeds are given in the neonatal unit, with full oral feeding often the last milestone to be achieved prior to discharge home. Unlike standard bottle teats, a vacuum release teat requires the application of negative intra-oral pressure to release milk, and so may facilitate breastfeeding in preterm infants. The objective of this study was to determine the effect of vacuum release teat use on timing of achievement of the first full oral feed and on first completion of 24 h full oral feeds. Feeding method at discharge home, 2 weeks, 6 weeks and 12 weeks corrected gestational age were also examined.

Methods

A randomized controlled trial was completed with mothers of preterm infants born 24–33 weeks gestation in the neonatal unit of a tertiary women’s hospital. Infants were randomized to one of two parallel groups using a vacuum release teat or standard teat for oral feeds when the mother was not available to breastfeed. Test weights were completed for all oral feeds. It was not possible to blind participants, care givers and outcome assessors to group assignment due to the nature of the study.

Results

The groups did not differ with regard to timing of achievement of first full oral feed or 24 h of full oral feeds. Significantly more infants in the vacuum release teat group were exclusively fed breast milk at discharge from hospital and breastfed at 3 months corrected gestational age.

Conclusions

Use of a vacuum release teat when the mother is not available to breastfeed may promote preterm breastfeeding skills, resulting in higher rates of exclusivity and longer breastfeeding duration.

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).
