Breastfeeding and childhood acute otitis media: a systematic review and meta-analysis

Factors associated with under-five mortality in Rwanda: An analysis of the Rwanda Demographic and Health Survey 2020

Despite global and Rwandan progress in reducing under-five mortality, the risk of children dying before their fifth birthday persists, necessitating intensified research on determinants. Thus, this study analyzed the birth history data to shed light on the underlying causes of under-five mortality in Rwanda. The study is a secondary analysis of data sourced from the 2020 Rwanda Demographic and Health Survey (RDHS) cross-sectional design. Using SPSS, the data was cleaned, recoded, and weighted, with descriptive and inferential statistics applied. The dependent variable was the child's living status, while independent variables included socio-demographic, media exposure status of mothers, child, and environmental factors. A total of 10267 under-five children of all interviewed mothers were included in the final analysis, of which 12.3% (1260) died. Maternal age (25-34 years: AOR = 1.514, 95% CI = 1.130-2.029, p = 0.005; 45+: AOR = 13.226, 95% CI = 9.253-18.905, p<0.001), occupational status (agricultural workers and other services), and three or more births within five years (AOR = 1.895, 95% CI = 1.433-2.508, p<0.001) significantly increase the risk of under-five mortality. Conversely, maternal education (primary: AOR = 0.821, p = 0.023; secondary: AOR = 0.533, p<0.001; higher: AOR = 0.365, p = 0.010) and higher wealth indexes (middle: AOR = 0.743, p = 0.001; rich: AOR = 0.612, p<0.001), as well as current breastfeeding (AOR = 0.524, 95% CI = 0.455-0.603, p-value <0.001), are associated with lower under-five mortality. Child sex significantly impacts under-five mortality (AOR = 0.873, 95% CI = 0.770-0.991, p = 0.035), favoring females over males. Conversely, multiple birth type children face higher under-five mortality (AOR = 3.541, 95% CI = 2.727-4.599, p<0.001) compared to singletons. Children in the northern (AOR = 1.478, 95% CI = 1.086-2.011, p = 0.013) and eastern (AOR = 1.470, 95% CI = 1.097-1.971, p = 0.010) regions are more susceptible to mortality compared to those in the central (Kigali) region. Additionally, under-five mortality is higher when using water from tanks and other sources (AOR = 2.240, 95% CI = 1.471-3.411, p<0.001) than piped water. This study identifies crucial factors linked to under-five mortality, underscoring the importance of prioritizing them in interventions to enhance Rwandan under-five survival rates.

Association between breastfeeding duration and diabetes mellitus in menopausal women: a machine-learning analysis using population-based retrospective study

BACKGROUND

Breastfeeding resets insulin resistance caused by pregnancy however, studies on the association between breastfeeding and diabetes mellitus (DM) have reported inconsistent results. Therefore, we aimed to investigate the risk of DM according to breastfeeding duration in large-scale population-based retrospective study. In addition, machine-learning prediction models for DM and hemoglobin A1c (HbA1c) were developed to further evaluate this association.

METHODS

We used the Korean National Health and Nutrition Examination Surveys database, a nationwide and population-based health survey from 2010 to 2020. We included 15,946 postmenopausal women with a history of delivery, whom we divided into three groups according to the average breastfeeding duration: (1) no breastfeeding, (2) < 12 months breastfeeding, and (3) ≥ 12 months breastfeeding. Prediction models for DM and HbA1c were developed using an artificial neural network, decision tree, logistic regression, Naïve Bayes, random forest, and support vector machine.

RESULTS

In total, 2248 (14.1%) women had DM and 14,402 (90.3%) had a history of breastfeeding. The prevalence of DM was the lowest in the < 12 breastfeeding group (no breastfeeding vs. < 12 months breastfeeding vs. ≥ 12 months breastfeeding; 161 [10.4%] vs. 362 [9.0%] vs. 1,725 [16.7%], p < 0.001). HbA1c levels were also the lowest in the < 12 breastfeeding group (HbA1c: no breastfeeding vs. < 12 months breastfeeding vs. ≥ 12 months breastfeeding; 5.9% vs. 5.9% vs. 6.1%, respectively, p < 0.001). After adjustment for covariates, the risk of DM was significantly increased in both, the no breastfeeding (adjusted odds ratio [aOR] 1.29; 95% CI 1.29, 1.62]) and ≥ 12 months of breastfeeding groups (aOR 1.18; 95% CI 1.01, 1.37) compared to that in the < 12 months breastfeeding group. The accuracy and the area under the receiver-operating-characteristic curve of the DM prediction model were 0.93 and 0.95, respectively. The average breastfeeding duration was ranked among the top 15 determinants of DM, which supported the strong association between breastfeeding duration and DM. This association was also observed in a prediction model for HbA1c.

CONCLUSIONS

Women who did not breasted had a higher risk of developing DM than those who breastfed for up to 12 months.

Skin-to-Skin Contact and Breastfeeding After Planned Cesarean Birth Before and During the COVID-19 Pandemic

Background: Benefits of early skin-to-skin contact (SSC) between mother and newborn are widely documented, including improved breastfeeding outcomes. While promoting immediate SSC is standard practice for vaginal birth, it happens less often after cesarean birth. It is not known how changes in hospital practices and staffing shortages during the COVID-19 pandemic have influenced the practice of SSC in the operating room (OR). This study aims to identify the relationship between SSC after cesarean birth and breastfeeding and compare SSC before and during the COVID-19 pandemic at a single institution. Materials and Methods: This was a retrospective cohort study of 244 subjects who had scheduled cesarean births during 2019 and 2020. The primary outcome was newborn feeding at hospital discharge. Secondary outcomes were time to initiate breastfeeding, newborn feeding at 4-8-weeks postpartum, and location of SSC initiation in 2019 versus 2020. Results: SSC within 3 days of birth was significantly associated with feeding type on discharge and/or 4-8 weeks postpartum. More subjects intending to exclusively breastfeed met this intention at discharge with SSC in the OR. Newborns who had SSC in the OR had significantly earlier initiation of breastfeeding. There was an increase in SSC in the OR between 2019 (27%) and 2020 (39%). Conclusion: SSC in the OR was associated with improved short-term breastfeeding outcomes in our study. If immediate SSC is not possible, SSC within 3 days of birth may have breastfeeding benefits. The increase in SSC in the OR during the COVID-19 pandemic indicates that SSC practices can be implemented, despite challenging circumstances.

Protective Characteristics of Human Breast Milk on Early Childhood Otitis Media: A Narrative Review

Introduction: Human breast milk (HBM) contains a complex and dynamically changing variety of factors that contribute to the infant's developing immune system's ability to fight upper respiratory tract infections, including otitis media (OM). We sought to summarize the current evidence on the protective characteristics of HBM, through direct or donated feeding, toward early childhood OM. Methods: For this narrative review, we performed a literature search on OM in the context of HBM feeding in the PubMed, Embase, and Google Scholar databases, between January 1, 2008, and July 1, 2023. Results: Immunoglobulin A (IgA) provides a short-term immunity of 2-3 days against otopathogens causing OM. IgA-mediated immunity is effective against OM up to 7 months of age if breastfeeding continues. The role of transferred IgM and IgG in HBM is unclear. Although there is a potential protective value of microRNA, hormones, oligosaccharides, stem cells, and interleukins present in HBM, their role is unclear. Any duration of breastfeeding is superior to no breastfeeding in OM risk reduction, with a big variability among studies (odds ratio 0.23-0.81, depending on the duration). Duration of breastfeeding ≥6 months was found to be the most effective in OM risk reduction, but there was no evidence of continued benefits after 2 years of age. Expressed breastfeeding was not shown to be more beneficial. The protective values of donor HBM against OM are still undetermined. Conclusion: HBM has numerous components that contribute to protection against early childhood OM.

Rational Design of an α-1,3-Fucosyltransferase for the Biosynthesis of 3-Fucosyllactose in Bacillus subtilis ATCC 6051a via De Novo GDP-l-Fucose Pathway

3-Fucosyllactose (3-FL) is an important oligosaccharide and nutrient in breast milk that can be synthesized in microbial cells by α-1,3-fucosyltransferase (α-1,3-FucT) using guanosine 5'-diphosphate (GDP)-l-fucose and lactose as substrates. However, the catalytic efficiency of known α-1,3-FucTs from various sources was limited due to their low solubility. To enhance the microbial production of 3-FL, the efficiencies of α-1,3-FucTs were evaluated and in Bacillus subtilis (B. subtilis) chassis cells that had been endowed with a heterologous synthetic pathway for GDP-l-fucose, revealing that the activity of FucTa from Helicobacter pylori (H. pylori) was higher than that of any of other reported homologues. To further improve the catalytic performance of FucTa, a rational design approach was employed, involving intracellular evaluation of the mutational sites of M32 obtained through directed evolution, analysis of the ligand binding site diversity, and protein structure simulation. Among the obtained variants, the FucTa-Y218 K variant exhibited the highest 3-FL yield, reaching 7.55 g/L in the shake flask growth experiment, which was 3.48-fold higher than that achieved by the wild-type enzyme. Subsequent fermentation optimization in a 5 L bioreactor resulted in a remarkable 3-FL production of 36.98 g/L, highlighting the great prospects of the designed enzyme and the strains for industrial applications.

Environmental risk factors for respiratory infection and wheeze in young children: A multicentre birth cohort study

INTRODUCTION

Respiratory infections and wheeze have a considerable impact on the health of young children and consume significant healthcare resources. We aimed to evaluate the effect of environmental factors on respiratory infections and symptoms in early childhood.

METHODS

Environmental risk factors including: daycare attendance; breastfeeding; siblings; damp within the home; environmental tobacco smoke (ETS); child's bedroom flooring; animal exposure; road traffic density around child's home; and solid fuel pollution within home were assessed in children recruited to the GO-CHILD multicentre prospective birth cohort study. Follow-up information on respiratory infections (bronchiolitis, pneumonia, otitis media and cold or flu), wheeze and cough symptoms, healthcare utilisation and medication prescription was collected by postal questionnaires at 12 and 24 months. Log binomial and ordered logistic regression models were fitted to the data.

RESULTS

Follow-up was obtained on 1344 children. Daycare was associated with increased odds of pneumonia (odds ratio [OR] = 2.39, 95% confidence interval [CI]: 1.04-5.49), bronchiolitis (OR = 1.40, 1.02-1.90), otitis media (OR = 1.68, 1.32-2.14) and emergency department attendance for wheeze (RR = 1.81, 1.17-2.80). Breastfeeding beyond 6 months was associated with a reduced odds of bronchiolitis (OR = 0.55, 0.39-0.77) and otitis media (OR = 0.75, 0.59-0.99). Siblings at home was associated with an increased odds of bronchiolitis (OR = 1.65, 1.18-2.32) and risk of reliever inhaler prescription (RR = 1.37, 1.02-1.85). Visible damp was associated with an increased odds of wheeze (OR = 1.85, 1.11-3.19), and risk of reliever inhaler (RR = 1.73, 1.04-2.89) and inhaled corticosteroid prescription (RR = 2.61, 1.03-6.59). ETS exposure was associated with an increased odds of primary care attendance for cough or wheeze (OR = 1.52, 1.11-2.08). Dense traffic around the child's home was associated with an increased odds of bronchiolitis (OR = 1.32, 1.08-2.29).

CONCLUSION

Environmental factors likely influence the wide variation in infection frequency and symptoms observed in early childhood. Larger population studies are necessary to further inform and guide public health policy to decrease the burden of respiratory infections and wheeze in young children.

Impact of Breastfeeding Duration on Adenoid Hypertrophy, Snoring and Acute Otitis Media: A Case-Control Study in Preschool Children

BACKGROUND

The aim of this study was to analyze the relationship between breastfeeding duration and adenoid size, snoring and acute otitis media (AOM).

METHODS

We analyzed the medical history of children admitted to the ENT outpatient clinic in 2022 and 2023, reported symptoms, ear, nose and throat (ENT) examination, and flexible nasopharyngoscopy examination of 145 children aged 3-5 years.

RESULTS

Breastfeeding duration of 3 and 6 months or more had a significant effect on the reduction of snoring (p = 0.021; p = 0.039). However, it had no effect on the adenoid size, mucus coverage and sleeping with an open mouth. Snoring was correlated with open mouth sleeping (p < 0.001), adenoid size with a 75% A/C ratio or more (p < 0.001), and adenoid mucus coverage in the Mucus of Adenoid Scale by Nasopharyngoscopy Assessment-MASNA scale (p = 0.009). Children who were breastfed for less than 3 months had more than a four-fold greater risk of snoring. There was a statistically significant correlation between AOM and gender (p = 0.033), breastfeeding duration in groups fed 1, 3 or 6 months or more (p = 0.018; p = 0.004; p = 0.004) and those fed with mother's breast milk 3 or 6 months or more (p = 0.009; p = 0.010). Moreover, a correlation was found between adenoid size and mucus coverage, tympanogram, and open-mouth sleeping (p < 0.001). Independent factors of snoring in 3- to 5-year-old children were breastfeeding duration of less than 3 months (p = 0.032), adenoid size with an A/C ratio of 75% or more (p = 0.023) and open mouth sleeping (p = 0.001).

CONCLUSIONS

Children breastfed for 3 and 6 months or more exhibited reduced rates of snoring. There was no effect of breastfeeding duration on adenoid size in children aged 3 to 5 years, suggesting that the link between breastfeeding duration and snoring is primarily associated with craniofacial development and muscle tone stimulation. A breastfeeding duration of 1 month or more plays a key role in reducing the rate of AOM. The mother's milk plays a protective role against AOM. The presence of mucus might be responsible for snoring in preschool children. A medical history of breastfeeding should be taken into consideration when snoring children are suspected of adenoid hypertrophy.

Post-insertion technique to introduce targeting moieties in milk exosomes for targeted drug delivery

BACKGROUND

Recently, increased attention has been given on exosomes as ideal nanocarriers of drugs owing to their intrinsic properties that facilitate the transport of biomolecular cargos. However, large-scale exosome production remains a major challenge in the clinical application of exosome-based drug delivery systems. Considering its biocompatibility and stability, bovine milk is a suitable natural source for large-scale and stable exosome production. Because the active-targeting ability of drug carriers is essential to maximize therapeutic efficacy and minimize side effects, precise membrane functionalization strategies are required to enable tissue-specific delivery of milk exosomes with difficulty in post-isolation modification.

METHODS

In this study, the membrane functionalization of a milk exosome platform modified using a simple post-insertion method was examined comprehensively. Exosomes were engineered from bovine milk (mExo) with surface-tunable modifications for the delivery of tumor-targeting doxorubicin (Dox). The surface modification of mExo was achieved through the hydrophobic insertion of folate (FA)-conjugated lipids.

RESULTS

We have confirmed the stable integration of functionalized PE-lipid chains into the mExo membrane through an optimized post-insertion technique, thereby effectively enhancing the surface functionality of mExo. Indeed, the results revealed that FA-modified mExo (mExo-FA) improved cellular uptake in cancer cells via FA receptor (FR)-mediated endocytosis. The designed mExo-FA selectively delivered Dox to FR-positive tumor cells and triggered notable tumor cell death, as confirmed by in vitro and in vivo analyses.

CONCLUSIONS

This simple and easy method for post-isolation modification of the exosomal surface may be used to develop milk-exosome-based drug delivery systems.

Influence of Breastfeeding on the State of Meta-Inflammation in Obesity-A Narrative Review

Obesity has become an emerging health issue worldwide that continues to grow in females of reproductive age as well. Obesity, as a multisystem and chronic disease, is associated with metabolic inflammation, which is defined as chronic low-grade systemic inflammation mediated by, i.a., adipose tissue macrophages. Lactation has been proven to have a beneficial influence on maternal health and could help restore metabolic balance, especially in the state of maternal obesity. In this review, we aimed to analyze the influence of breastfeeding on chronic low-grade meta-inflammation caused by obesity. We performed a comprehensive literature review using the PubMed, Science Direct, and Google Scholar electronic databases. For this purpose, we searched for "metabolic inflammation"; "meta-inflammation"; "obesity"; "breastfeeding"; "fetal programming"; "energy metabolism"; "postpartum"; "immunity"; "immune system"; and "inflammation" keyword combinations. While the clinical impact of breastfeeding on maternal and offspring health is currently well known, we decided to gain insight into more specific metabolic effects of adiposity, lipid, and glucose homeostasis, and immunological effects caused by the activity of cytokines, macrophages, and other immune system cells. Further research on the immunological and metabolic effects of breastfeeding in obese patients is key to understanding and potentially developing obesity therapeutic strategies.

Predicting intention and maintenance of breastfeeding up to 2-years after birth in primiparous and multiparous women

OBJECTIVES

Breastfeeding up to 2-years has been associated with short and long-term health benefits for both newborns and mothers. However, few women breastfeed up to 2-years after birth. This study extends previous research on the theory of planned behaviour (TPB) examining the predictors of intention and maintenance of breastfeeding up to 2-years in both primiparous and multiparous women.

DESIGN

155 pregnant women participated in this longitudinal study.

METHODS

Expectant mothers completed a questionnaire and then 2-years after the child's birth were asked to report breastfeeding behaviour. Interactions among parity and TPB constructs were examined.

RESULTS

Attitudes, descriptive and injunctive norms, and perceived behavioural control (PBC) explained 58% of the variance in mothers' intention to breastfeed. Attitudes were the strongest predictor, followed by PBC, descriptive norms and parity. A significant interaction was found between parity and PBC, showing that PBC was only a significant predictor of intention to breastfeed at 2-years in multiparous women. Intentions predicted breastfeeding behaviour at 2-years.

CONCLUSION

Promoting intentions may be a useful way to increase breastfeeding duration to 2-years and targeting attitudes and norms may be one way to increase intentions. Further, targeting PBC may also be useful to increase intentions, but only in multiparous women.

Determinants of early initiation of breastfeeding in The Gambia: a population-based study using the 2019-2020 demographic and health survey data

BACKGROUND

Early initiation of breastfeeding within the first hour of life prevents neonatal and infant mortality. Sustainable Development Goals (SDGs) Target 3.2 aims to reduce neonatal mortality and under 5 mortality globally. The decline in the early initiation of breastfeeding in The Gambia coincides with deviations from the SDGs, due to poor indicators of child survival. Our work studied the determinants of early initiation of breastfeeding in The Gambia.

METHODS

We used the 2019-2020 Gambia Demographic Health Survey (GDHS) conducted across all regions of the country. Since our population of interest was children born two years preceding the study, we only included children less than 24 months of age, living with an eligible respondent. Thus, a weighted sample of 5691 mother-child pairs was applied in the analysis. We reported summary statistics of individuals' sociodemographic, obstetrics and antenatal, household, and community-level factors. A logistic regression model was used to determine associations between early initiation of breastfeeding and covariates.

RESULTS

The prevalence of early initiation of breastfeeding was 64.3% (n = 3659). Mothers who had secondary education or higher educational level had higher odds of early initiation of breastfeeding (AOR 1.22; 95% CI 1.07, 1.40). Regions with rural population notably Lower and Central and Upper River Region had lower odds of early initiation of breastfeeding [Mansakonko (AOR 0.37; 95% CI 0.26, 0.15), Kerewan (AOR 0.26; 95% CI 0.19, 0.36), Kuntaur (AOR 0.39; 95% CI 0.28, 0.54), Janjanbureh (AOR 0.48; 95% CI 0.35, 0.66) and Basse (AOR 0.64; 95%CI 0.49, 0.85)]. Also, women in the high quintile of the wealth index were more likely to initiate breastfeeding early (AOR 1.29; 95% CI 1.06, 1.57). Four or more antenatal care visits did not increase early initiation of breastfeeding.

CONCLUSIONS

The results of the analyses demand affirmative action to improve maternal education, reduce poverty and inequality and empower rural communities in The Gambia. The IYCF component in antenatal care needs to be strengthened. Programs and policies on IYCF must resonate to address determinants of timely breastfeeding initiation to chart progress towards the SDG.

Is breastfeeding in MS harmful or not? An answer from real-world Czech data

INTRODUCTION

The influence of breastfeeding and it´s duration on the course of multiple sclerosis (MS) is unclear. Here we analyzed a real-world data for breastfeeding women with MS and their disease course collected from a Czech national registry ReMuS.

OBJECTIVES

To identify risk factors associated with not initiating breastfeeding after delivery, to analyze the impact of breastfeeding on the MS disease course, evaluate the assumption, that breastfeeding is not harmful in MS patients, and compare the disease course by breastfeeding status.

MATERIALS AND METHODS

Using propensity score matching we compared Expanded Disability Status Scale (EDSS), confirmed disease worsening (CDW) and annual relapse rate (ARR) in breastfeeding and non-breastfeeding MS patients according to disease duration, disease modifying treatment (DMT) before pregnancy, last EDSS score before conception, age, and ARR during pregnancy. We also compared these parameters between breastfeeding patients not using a DMT and non-breastfeeding patients who resumed DMT within 3 months after delivery. EDSS, ARR, and CDW were collected at 12, 24, and 36 months after delivery.

RESULTS

A total of 1681 pregnancies that ended in delivery were analyzed from 2013 through 2020. Change in ARR and EDSS values and 6-months CDW did not significantly differ between the analyzed groups. Compared with non-breastfeeding women who resumed DMT early after delivery, breastfeeding women with MS did not experience worse clinical outcomes even without initiating a DMT.

DISCUSSION

Breastfeeding in Czech women with MS did not negatively affect the disease course and can be supported. Patients with MS can be treated with certain DMTs alongside breastfeeding and there is no need to stop breastfeeding, if the patient is clinically stable.

Key biologically active components of breast milk and their beneficial effects

Maternal breast milk is the penultimate nutritional source for term and preterm neonates. Its composition is highly complex and includes multiple factors that enhance the development of nearly every neonatal organ system leading to both short- and long-term health benefits. Intensive research is focused on identifying breast milk components that enhance infant health. However, this research is complicated by the significant impact of maternal factors and the processing of pumped breast milk on bioactive ingredients. Optimizing enteral nutrition is particularly important for preterm neonates who miss the transplacental acquisition of nutrients in the third trimester of pregnancy and are at risk for illnesses associated with gut barrier dysfunction, including sepsis and necrotizing enterocolitis. In this review, we will discuss the health benefits of breast milk and its bioactive components.

The Impact of the Human Milk Microbiota in the Prevention of Disease and Infant Health

Background: Human milk is recognized as an ideal food for newborns and infants owing to the presence of various nutritive factors, including healthy bacteria. Aim/Objective: This review aimed to understand the effects of human milk microbiota in both the prevention of disease and the health of infants. Methods: Data were obtained from PubMed, Scopus, Web of Science, clinical trial registries, Dergipark, and Türk Atıf Dizini up to February 2023 without language restrictions. Results: It is considered that the first human milk microbiota ingested by the newborn creates the initial microbiome of the gut system, which in turn influences the development and maturation of immunity. Bacteria present in human milk modulate the anti-inflammatory response by releasing certain cytokines, protecting the newborn against certain infections. Therefore, certain bacterial strains isolated from human milk could serve as potential probiotics for various therapeutic applications. Conclusions: In this review, the origin and significance of human milk bacteria have been highlighted along with certain factors influencing the composition of human milk microbiota. In addition, it also summarizes the health benefits of human milk as a protective agent against certain diseases and ailments.

New insights into the treatment of acute otitis media

INTRODUCTION

Acute otitis media (AOM) affects most (80%) children by 5 years of age and is the most common reason children are prescribed antibiotics. The epidemiology of AOM has changed considerably since the widespread use of pneumococcal conjugate vaccines, which has broad-reaching implications for management.

AREAS COVERED

In this narrative review, we cover the epidemiology of AOM, best practices for diagnosis and management, new diagnostic technology, effective stewardship interventions, and future directions of the field. Literature review was performed using PubMed and ClinicalTrials.gov.

EXPERT OPINION

Inaccurate diagnoses, unnecessary antibiotic use, and increasing antimicrobial resistance remain major challenges in AOM management. Fortunately, effective tools and interventions to improve diagnostic accuracy, de-implement unnecessary antibiotic use, and individualize care are on the horizon. Successful scaling of these tools and interventions will be critical to improving overall care for children.

The Link between Different Types of Prebiotics in Infant Formula and Infection Rates: A Review

Breastfeeding plays a protective role against infections, partially through the prebiotic effect of human milk oligosaccharides (HMOs). Aiming to mimic these beneficial capacities, there is an ongoing search to make infant formula closer to human milk, including by adding oligosaccharides. Over the past two decades, multiple studies have been published on different types of prebiotics and their role in reducing infection rates in infants. This review aims to answer the question of whether there is evidence that the addition of oligosaccharides to infant formula decreases the prevalence of infection, and whether the effect is influenced by the kind of oligosaccharide added. The review of the literature reveals an important heterogeneity, including different types and dosages of prebiotics, different intervention periods and inclusion criteria, etc., making it impossible to formulate a consensus about the efficacy of adding prebiotics to infant formula. We would cautiously suggest that supplementation with galactooligosaccharides (GOSs)/fructooligosaccharides (FOSs) seems to have a beneficial effect on infection rates. For HMOs, more studies about the different types of HMOs are necessary to make any deductions. GOSs alone, inulin, and MOSs (bovine-milk-derived oligosaccharides) do not reduce the incidence of infections. The combination of GOSs and PDX (polydextrose) was found to play a protective role in one study. The evidence of the effect of prebiotics in reducing the use of antibiotics is low. The many lacunas in the direction of study uniformity offer many opportunities for further research.

No such thing as a free lunch: The direct marginal costs of breastfeeding

Understanding costs associated with breastfeeding is critical to developing maximally effective policy to support breastfeeding by addressing financial barriers. Breastfeeding is not without cost; direct costs include those of equipment, modified nutritional intake, and time (opportunity cost). Breastfeeding need not require more equipment than formula feeding, though maternal equipment use varies by maternal preference. Meeting increased nutritional demands requires increased spending on food and potentially dietary supplementation, the marginal cost of which depends on a mother's baseline diet. The opportunity cost of the three to four hours per day breastfeeding demands may be prohibitively high, particularly to low-income workers. These costs are relatively highest for low-income individuals, a group disproportionately comprising racial and ethnic minorities, and who demonstrate lower rates of breastfeeding than their white and higher-income peers. Acknowledging and addressing these costs and their regressive nature represents a critical component of effective breastfeeding policy and promotion.

Does benefits-of-breastfeeding language or risks-of-formula-feeding language promote more-positive attitudes toward breastfeeding among midwives and nurses?

BACKGROUND

Midwives and nurses are crucial in breastfeeding support. Few studies have explored appropriate language for nursing education on breastfeeding. We assessed the impact of the language used on breastfeeding attitudes among midwives and nurses.

METHODS

A quasi-experimental study was conducted online in Japan among 174 midwives and nurses who had work experience in obstetrics or pediatrics. Participants were allocated to three groups to receive different text messages as the intervention (the benefit of breastfeeding for Group 1; the risk of formula feeding for Group 2; the importance of childcare for Group 3 as the comparison). The Japanese version of the Iowa Infant Feeding Attitude Scale (IIFAS-J) was used to assess breastfeeding attitudes before and after reading the texts. Also, participant reactions to the text were assessed by their responses to three statements. ANOVA, the chi-square test, and the t-test were used for outcome assessments.

RESULTS

The post-test IIFAS-J score was significantly higher than the pre-test score only for Group 1 (p <  0.01). The percentage of participants who agreed with the content of the text was 70.7% in Group 1 and 48.3% in Group 2. The percentage of participants who reported discomfort with the text was 34.5% in Group 1 and 55.2% in Group 2. No significant difference among groups existed regarding interest in the text. In all three groups, participants who agreed with the text had a higher post-test IIFAS-J score than those who disagreed with the text (6.85 points higher, p <  0.01 in Group 1; 7.19 points higher, p <  0.01 in Group 2; 8.00 points higher, p <  0.02 in Group 3). Discomfort with the text and interest in the text were associated with a significantly higher post-test IIFAS-J score in Group 1 and Group 2 but not in Group 3.

CONCLUSIONS

"Benefits of breastfeeding" language, which conveys the information in a positive manner, appears to be more appropriate than "risks of infant formula" language for creating a positive attitude toward breastfeeding in nursing education.

Factors associated with breastfeeding initiation and maintenance for Aboriginal and Torres Strait Islander women in Australia: A systematic review and narrative analysis

BACKGROUND

Australian Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal) women breastfeed at lower rates than non-Aboriginal women. Little is known about factors associated with breastfeeding specific to Aboriginal women and infants.

AIM

Determine the protective and risk factors associated with breastfeeding for Aboriginal women in Australia.

METHODS

CINAHL, Medline, EMBASE, SCOPUS, PsycINFO, and the Cochrane library were searched for peer-reviewed literature published between 1995 and 2021. Quantitative studies written in English reporting protective and risk factors associated with breastfeeding for Aboriginal women or women having an Aboriginal infant were included. Ten percent of papers were co-screened, and two reviewers completed data extraction. Narrative data synthesis was used.

FINDINGS

The initial search identified 12,091 records, with 31 full text studies retrieved, and 17 reports from 14 studies met inclusion criteria. Protective factors included living in a remote area, attending an Aboriginal-specific service, attending a regional service, higher levels of education attainment, increased maternal age, living in larger households, being partnered, and having a higher reported number of stressful events and social health issues. The identified risk factors were smoking in pregnancy, admission to SCN or NICU, and being multiparous.

CONCLUSION

This review identified factors associated with breastfeeding for Aboriginal women. Government focus, support, and consistent funding are required to plan and implement evidence-based interventions and services for Aboriginal women and infants in urban, rural, remote, and very remote locations. Rigorous research is required to understand the Aboriginal-specific factors associated with breastfeeding to improve rates and health outcomes for Aboriginal women and infants.

Factors associated with exclusive formula feeding among individuals with low-risk pregnancies in the United States

BACKGROUND

Better understanding of the factors associated with formula feeding during the hospital stay can help in identifying potential lactation problems and promote early intervention. Our aim was to ascertain factors associated with exclusive formula feeding in newborns of low-risk pregnancies.

METHODS

A population-based, retrospective study using the United States vital statistics datasets (2014-2018) evaluating low-risk pregnancies with a nonanomalous singleton delivery from 37 to 41 weeks. People with hypertensive disorders, or diabetes, were excluded. Primary outcome was newborn feeding (breast vs exclusive formula feeding) during hospital stay. Adjusted relative risks (aRRs) with 95% confidence intervals (CI) were calculated.

RESULTS

Of the 19 623 195 live births during the study period, 11 605 242 (59.1%) met inclusion criteria and among them, 1 929 526 (16.6%) were formula fed. Factors associated with formula feeding included: age < 20 years (aRR 1.31 [95% CI 1.31-1.32]), non-Hispanic Black (1.42, 1.41-1.42), high school education (1.69, 1.69-1.70) or less than high school education (1.94, 1.93, 1.95), Medicaid insurance (1.52, 1.51, 1.52), body mass index (BMI) < 18.5 (1.10, 1.09-1.10), BMI 25-29.9 (1.09, 1.09-1.09), BMI 30-34.9 (1.19, 1.19-1.20), BMI 35-39.9 (1.31, 1.30-1.31), BMI ≥ 40 (1.43, 1.42-1.44), multiparity (1.29, 1.29-1.30), lack of prenatal care (1.49, 1.48-1.50), smoking (1.75, 1.74-1.75), and gestational age (ranged from 37 weeks [1.44, 1.43-1.45] to 40 weeks [1.11, 1.11-1.12]).

CONCLUSIONS

Using a large cohort of low-risk pregnancies, we identified several modifiable factors associated with newborn feeding (eg, prepregnancy BMI, access to prenatal care, and smoking cessation). Improving the breast feeding initiation rate should be a priority in our current practice to ensure equitable care for all neonates.

Factors influencing infant feeding for Aboriginal and Torres Strait Islander women and their families: a systematic review of qualitative evidence

BACKGROUND

Breastfeeding provides all the necessary energy and nutrients for an infant and provides many benefits for mothers and babies. The effects of colonisation have contributed to reduced prevalence and duration of breastfeeding among Australian Aboriginal women and widespread use of infant formula as a substitute for breastmilk. This review aimed to synthesise qualitative evidence about the factors that influence breastfeeding and infant feeding practices of Aboriginal and Torres Strait Islander women and their families.

METHODS

MEDLINE, CINAHL, Informit and Google Scholar were systematically searched for qualitative studies that included the perspective of Aboriginal and Torres Strait Islander women and their families about the factors influencing infant feeding decisions. Included studies were appraised using an Indigenous quality assessment tool and were synthesised via inductive thematic analysis informed by an ecological framework.

RESULTS

The search identified 968 studies with 7 meeting the inclusion criteria. Key factors influencing breastfeeding and infant feeding practices of Aboriginal women included cultural practices, normalisation of bottle feeding, shame associated with breastfeeding in public, access to culturally safe nutrition education, support services and health professionals, family/partner support, knowledge of the benefits of breastfeeding, experiences with previous babies and concern that the baby was not getting enough milk.

CONCLUSION

The perspectives of Aboriginal and Torres Strait Islander women must be considered when providing breastfeeding and infant feeding advice. This can be achieved through Aboriginal and Torres Strait Islander people designing, implementing, and leading the delivery of education and information regarding breastfeeding and health infant feeding practices that have been influenced by the priorities of Aboriginal and Torres Strait Islander communities.

Breastfeeding reduces the risk of breast cancer: A call for action in high-income countries with low rates of breastfeeding

Women in the UK have a 15% lifetime risk of developing breast cancer. Like other high-income countries, women in the UK are having children later in life which increases their risk. The risk of breast cancer is reduced by 4.3% for every 12 months of breastfeeding, this is in addition to the 7.0% decrease in risk observed for each birth. Breastfeeding reduces the risk of Triple-Negative Breast Cancer (20%) and in carriers of BRCA1 mutations (22-55%). The mechanisms of reduced risk as a result of pregnancy are related to changes in RNA processing and cellular differentiation. The UK has a low rate of breastfeeding (81%) and this is contrasted to countries with higher (Sweden, Australia) and lower rates (Ireland). The low UK rate is in part due to a lack of experience in the population, todays grandmothers have less experience with breastfeeding (62%) than their daughters. An estimated 4.7% of breast cancer cases in the UK are caused by not breastfeeding. The UK only has 43% of maternity services with full Baby-Friendly accreditation which promotes compliance with the WHO 'Ten Steps to Successful Breast Feeding'. Legislation in the UK and Europe is far short of the WHO Guidance on restricting the advertising of formula milk. Expansion of the Baby-Friendly Hospital Initiative, stricter laws on the advertising of formula milk and legislation to support nursing mothers in the workplace have the potential to increase breastfeeding in the UK. Women with a family history of breast cancer should particularly be supported to breastfeed as a way of reducing their risk.

Interventions for promoting and optimizing breastfeeding practices: An overview of systematic review

Background

Optimal breastfeeding (BF) practices are essential for child survival and proper growth and development. The purpose of this overview is to evaluate the effectiveness of different interventions for promoting and optimizing breastfeeding.

Methods

We included systematic reviews (SRs) [including trials from Low-Income (LICs) and Low Middle-Income countries (LMICs)] that have evaluated the effect of various interventions for promoting and optimizing breastfeeding and excluded non-systematic reviews, and SRs based on observational studies. We searched various electronic databases. We followed the standard methodology as suggested by the Cochrane Handbook for Systematic Reviews of Interventions. Two sets of reviewers undertook screening followed by data extraction and assessment of the methodological quality of included SRs.

Result

We identified and screened 1,002 Cochrane SRs and included six SRs in this overview. Included SRs reported only two of the primary outcomes, early initiation of breastfeeding (EIBF) and/or exclusive breastfeeding (EBF). None of the included SR reported continued BF up to 2 years of age. The results were evaluated using two major comparisons groups: BF intervention against routine care and one type of BF intervention vs. other types of BF intervention. Overall results from included SRs showed that there were improvements in the rates of EIBF and EBF among women who received BF intervention such as BF education sessions and support compared to those women who received only standard care. However, BF intervention via mobile devices showed no improvements. In Target Client Communication (TCC) via mobile devices intervention group, no significant improvements were reported in BF practices, and also the reported evidence was of very low certainty.

Conclusion

Community Based Intervention Packages (CBIP) delivered to pregnant and reproductive-age women during their Antenatal care (ANC) and/or Postnatal care (PNC) periods by Ancillary Nurse-Midwives reported the highest improvement in EIBF compared to women who received standard care. However, insufficient evidence was reported to suggest that BF intervention showed improvements in EBF in both the comparison groups. This overview highlighted the gaps in primary research regarding the uncertainty about the settings such as LICs or LMICs, lack of evidence from LMICs, and also identified gaps in the availability of reliable up-to-date SRs on the effects of several BF interventions to promote and optimize practices.

The effect of Pimpinella Anisum herbal tea on human milk volume and weight gain in the preterm infant: a randomized controlled clinical trial

BACKGROUND AND AIMS

Human milk supports pre-term infants to thrive. Yet human milk production can be inhibited when infants are born prematurely. Pimpinella Anisum has been evidenced to increase milk production and infant weight gain in previous animal studies. The present study aimed to determine the effect of Pimpinella Anisum herbal tea on human milk volume and preterm infant weight in human populations for the first time.

METHODS

Human milk supports pre-term infants to thrive. Yet human milk production can be inhibited when infants are born prematurely. Pimpinella Anisum has been evidenced to increase milk production and infant weight gain in previous animal studies. The present study aimed to determine the effect of Pimpinella Anisum herbal tea on human milk volume and preterm infant weight in human populations for the first time.

RESULTS

There was a statistically significant difference in terms of milk volume in the first, third, fourth, fifth, sixth and seventh days between the three groups of intervention, placebo, and control (p < 0.05). On the first day, the mean volume of pumped milk in the intervention group was significantly higher than the control group (p = 0.008). On the second day, there was no statistically significant difference between groups. On the third, fourth, fifth, sixth and seventh days, the mean volume of pumped milk in the intervention group was significantly higher than the placebo and control groups (p < 0.05). There was no statistically significant difference in terms of preterm infant weight on days 0, 3 and 7 between the three groups.

CONCLUSION

The use of Pimpinella Anisum or 'Anise' tea can increase the volume of human milk and since no specific side effects have been reported in its use, it may be incorporated easily, cheaply, and effectively in practice where appropriate to the benefit of preterm infant nutrition worldwide.

Development of SARS-CoV-2 specific IgG and IgA antibodies in serum and milk with different SARS-COV-2 vaccines in lactating women

BACKGROUND

Our main objective was to determine the evolution of IgG and IgA antibodies directed against SARS-CoV-2 protein S in the blood of lactating women and in breast milk.

METHODS

A cohort of 110 uninfected and vaccinated breastfeeding women was followed-up for 6 months at the Marqués de Valdecilla University Hospital, Spain, in 2020. An additional group of 23 breastfeeding mothers who had no previously documented infection and had not been vaccinated against SARS-CoV-2 were included as a control group. The antibodies in blood and breast milk and their evolution at 6 months post-vaccination were analysed.

RESULTS

One hundred ten breastfeeding mothers were included; 70 women (63.6%) were vaccinated with two doses of BNT162b2, 20 women (18.2%) received two doses of mRNA-1273, and 20 women (18.2%) received a single dose of ChAdOx1-S. No evidence of differences between concentrations of antibodies was found according to the type of vaccine, with the exception of serum IgA antibodies, which was higher in women vaccinated with mRNA-1273: mean [95%CI]: 0.05 AU/mL [0.03,0.06] with mRNA-1273, 0.02 AU/mL [0.01,0.03] with BNT162b2 and 0.01 AU/mL [0.00,0.03] with ChAdOx1-S, ANOVA p value = 0.03. The lack of difference between vaccines was also found when anti-S1 specific IgG in serum and breast milk were measured.

CONCLUSIONS

In lactating women vaccinated against COVID-19, anti-SARS-CoV-2 antibodies can be detected in both serum and breastmilk 6 months after receiving the second dose, although their concentrations decreased when compared with concentrations reached immediately after vaccination.

Protective Effect of Breastfeeding Against Febrile Seizure: A Nationwide Study in Korea

BACKGROUND

Breastfeeding is known to protect against febrile seizure (FS). Whether its impact continues throughout the childhood period is still controversial. Our objective was to investigate the protective effect of breastfeeding against FS stratified by age.

METHODS

We included children who participated in the National Health Screening Program for Infants and Children (NHSPIC) aged between four and six months between 2008 and 2014. Feeding type was confirmed based on the NHSPIC questionnaire, and data from the Korean National Health Insurance Service were used to determine FS cases during a five-year follow-up period.

RESULTS

Among the 1,791,335 children, the most prevalent feeding type was exclusive breastfeeding (EB) (42.3%). FS occurred most frequently in the exclusive formula feeding (EF) group (12.2%), followed by the partial breastfeeding (PB) (11.3%) and EB groups (10.7%). Compared with the EF group, the adjusted odds ratio for FS was 0.87 (95% confidence interval, 0.86 to 0.88, P < 0.001) and 0.93 (0.92 to 0.94, P < 0.001) in the EB and PB groups, respectively. The protective effect by age 2.5 years was significant in both the EB (0.85; 0.84 to 0.86, P < 0.001) and PB (0.92; 0.90 to 0.93, P < 0.001) groups. In contrast, the protective effect was not significant in the PB group and inconsistent in the EB group after 2.5 years.

CONCLUSION

Breastfeeding has a protective effect against FS in the most prevalent age period, from 0 to 2.5 years. Despite the limited effect after age 2.5 years, we support the current recommendation for prolonged breastfeeding to promote childhood health.

Exclusive Breastfeeding and Childhood Morbidity: A Narrative Review

Globally, diarrheal diseases and acute respiratory infections are the leading causes of morbidity and mortality in children under 5 years old. The benefits of exclusive breastfeeding in reducing the risk of gastrointestinal and respiratory infections are well documented. Optimal breastfeeding may potentially save the lives of about 800,000 children in low-income settings. Despite the evidence, around 63% of infants from birth to 6 months are not exclusively breastfed worldwide. We searched the literature published between 2010 and 2022 in Medline, Embase, and Scopus on the association between exclusive breastfeeding and infectious diseases. We selected and reviewed 70 relevant studies. Our findings expand and confirm the positive association between exclusive breastfeeding and reduced risk of a number of gastrointestinal, respiratory, and other infections in 60 out of 70 studies observed in both low- and high-income settings. Several studies analyzing exclusive breastfeeding duration reported that a longer exclusive breastfeeding duration is protective against many infectious diseases. This review also reported a lack of standardized definition for measuring exclusive breastfeeding in many studies. Overall, the results highlight the benefits of exclusive breastfeeding in many studies and suggests reporting exclusive breastfeeding in future studies using a consistent definition to enable better monitoring of exclusive breastfeeding rates.

Establishing breast feeding in infants with Down syndrome: the FADES cohort experience

OBJECTIVE

To describe breastfeeding prevalence and maternal experience in infants with trisomy 21.

DESIGN

Longitudinal cohort study.

SETTING

Participants from UK recruited through websites, social media and local collaborators: neonatologists, community paediatricians and research nurses.

SUBJECTS

Infants under the age of 8 months with Down syndrome (DS) recruited to the Feeding and Autoimmunity in Down Syndrome Evaluation Study between 1 September 2014 and 31 August 2017. Seventy participants: median age 20 weeks (IQR 13-29 weeks) at initial questionnaire.

MAIN OUTCOME MEASURE

Breastfeeding prevalence at 6 weeks and 6 months among infants with DS.

RESULTS

The prevalence of exclusive breast feeding among study participants was similar to the general population (13/61, 21% vs 23% at 6 weeks, 2/54, 4% vs 1% at 6 months). However, the prevalence of breast feeding (exclusive or combination feeding) among the study participants was higher than the general population (39/61 64% vs 55% at 6 weeks, 32/59 54% vs 34% at 6 months).

CONCLUSION

Although there may be challenges in establishing breast feeding in infants with DS, our data suggest that exclusive breast feeding is possible for some, and the prevalence of breast feeding is comparable to the prevalence in the general population.

Breastfeeding rates of Aboriginal and Torres Strait Islander women in Australia: a systematic review and narrative analysis

BACKGROUND

Australian Aboriginal and Torres Strait Islander (referred to hereafter as Aboriginal) women breastfeed at lower rates than non-Aboriginal women, and rates vary across and within Aboriginal populations.

AIM

To determine rates of breastfeeding initiation and maintenance and compare individually collected survey data with existing routinely collected state and national breastfeeding data for Aboriginal women.

METHODS

CINAHL, Medline, EMBASE, SCOPUS, PsycINFO, and the Cochrane library were searched for peer-reviewed literature published between 1995 and 2021. Quantitative studies written in English and reporting breastfeeding for Aboriginal women or women having an Aboriginal infant were included. Screening and quality assessment included co-screening 10% of papers. Two reviewers completed data extraction. A proportional meta-analysis was undertaken for breastfeeding initiation and narrative data synthesis used to summarise breastfeeding maintenance.

FINDINGS

The initial search identified 12,091 records, with 31 full text studies retrieved, and 27 reports from 22 studies met inclusion criteria. Breastfeeding initiation was 78% (95% CI 0.71, 0.84), however, rates were lower than non-Aboriginal women. Maintenance ranged between one week and five years. Rates and definitions varied significantly between studies, with inconsistencies in government collection and reporting of breastfeeding.

CONCLUSION

Significant variation in definitions and reporting make comparisons difficult. Breastfeeding rates were below recommended targets. Future pattern and trend analyses require standardised measures and definitions. Current collection and reporting of breastfeeding data, particularly routinely collected state-based data, is inadequate to present an accurate picture of current breastfeeding in Australia for Aboriginal women and infants, and to effectively inform interventions and policies.

Support for healthy breastfeeding mothers with healthy term babies

BACKGROUND

There is extensive evidence of important health risks for infants and mothers related to not breastfeeding. In 2003, the World Health Organization recommended that infants be breastfed exclusively until six months of age, with breastfeeding continuing as an important part of the infant's diet until at least two years of age. However, current breastfeeding rates in many countries do not reflect this recommendation.

OBJECTIVES

1. To describe types of breastfeeding support for healthy breastfeeding mothers with healthy term babies. 2. To examine the effectiveness of different types of breastfeeding support interventions in terms of whether they offered only breastfeeding support or breastfeeding support in combination with a wider maternal and child health intervention ('breastfeeding plus' support).  3. To examine the effectiveness of the following intervention characteristics on breastfeeding support:      a. type of support (e.g. face-to-face, telephone, digital technologies, group or individual support, proactive or reactive);      b. intensity of support (i.e. number of postnatal contacts);      c. person delivering the intervention (e.g. healthcare professional, lay person);     d. to examine whether the impact of support varied between high- and low-and middle-income countries.

SEARCH METHODS

We searched Cochrane Pregnancy and Childbirth's Trials Register (which includes results of searches of CENTRAL, MEDLINE, Embase, CINAHL, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform (ICTRP)) (11 May 2021) and reference lists of retrieved studies.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials comparing extra support for healthy breastfeeding mothers of healthy term babies with usual maternity care. Support could be provided face-to-face, over the phone or via digital technologies. All studies had to meet the trustworthiness criteria.  DATA COLLECTION AND ANALYSIS: We used standard Cochrane Pregnancy and Childbirth methods. Two review authors independently selected trials, extracted data, and assessed risk of bias and study trustworthiness.  The certainty of the evidence was assessed using the GRADE approach.

MAIN RESULTS

This updated review includes 116 trials of which 103 contribute data to the analyses. In total more than 98,816 mother-infant pairs were included.  Moderate-certainty evidence indicated that 'breastfeeding only' support probably reduced the number of women stopping breastfeeding for all primary outcomes: stopping any breastfeeding at six months (Risk Ratio (RR) 0.93, 95% Confidence Interval (CI) 0.89 to 0.97); stopping exclusive breastfeeding at six months (RR 0.90, 95% CI 0.88 to 0.93); stopping any breastfeeding at 4-6 weeks (RR 0.88, 95% CI 0.79 to 0.97); and stopping exclusive breastfeeding at 4-6 (RR 0.83 95% CI 0.76 to 0.90). Similar findings were reported for the secondary breastfeeding outcomes except for any breastfeeding at two months and 12 months when the evidence was uncertain if 'breastfeeding only' support helped reduce the number of women stopping breastfeeding.  The evidence for 'breastfeeding plus' was less consistent. For primary outcomes there was some evidence that 'breastfeeding plus' support probably reduced the number of women stopping any breastfeeding (RR 0.94, 95% CI 0.91 to 0.97, moderate-certainty evidence) or exclusive breastfeeding at six months (RR 0.79, 95% CI 0.70 to 0.90).  'Breastfeeding plus' interventions may have a beneficial effect on reducing the number of women stopping exclusive breastfeeding at 4-6 weeks, but the evidence is very uncertain (RR 0.73, 95% CI 0.57 to 0.95). The evidence suggests that 'breastfeeding plus' support probably results in little to no difference in the number of women stopping any breastfeeding at 4-6 weeks (RR 0.94, 95% CI 0.82 to 1.08, moderate-certainty evidence). For the secondary outcomes, it was uncertain if 'breastfeeding plus' support helped reduce the number of women stopping any or exclusive breastfeeding at any time points.  There were no consistent findings emerging from the narrative synthesis of the non-breastfeeding outcomes (maternal satisfaction with care, maternal satisfaction with feeding method, infant morbidity, and maternal mental health), except for a possible reduction of diarrhoea in intervention infants.  We considered the overall risk of bias of trials included in the review was mixed. Blinding of participants and personnel is not feasible in such interventions and as studies utilised self-report breastfeeding data, there is also a risk of bias in outcome assessment.   We conducted meta-regression to explore substantial heterogeneity for the primary outcomes using the following categories: person providing care; mode of delivery; intensity of support; and income status of country.  It is possible that moderate levels (defined as 4-8 visits) of 'breastfeeding only' support may be associated with a more beneficial effect on exclusive breastfeeding at 4-6 weeks and six months. 'Breastfeeding only' support may also be more effective in reducing women in low- and middle-income countries (LMICs) stopping exclusive breastfeeding at six months compared to women in high-income countries (HICs). However, no other differential effects were found and thus heterogeneity remains largely unexplained. The meta-regression suggested that there were no differential effects regarding person providing support or mode of delivery, however, power was limited.  AUTHORS' CONCLUSIONS: When 'breastfeeding only' support is offered to women, the duration and in particular, the exclusivity of breastfeeding is likely to be increased. Support may also be more effective in reducing the number of women stopping breastfeeding at three to four months compared to later time points.  For 'breastfeeding plus' interventions the evidence is less certain. Support may be offered either by professional or lay/peer supporters, or a combination of both. Support can also be offered face-to-face, via telephone or digital technologies, or a combination and may be more effective when delivered on a schedule of four to eight visits. Further work is needed to identify components of the effective interventions and to deliver interventions on a larger scale.

Exact Gestational Age, Term Versus Early Term, Is Associated with Different Breastfeeding Success Rates in Mothers Delivered by Elective Cesarean Section

Objectives: The study was intended to verify the association between the gestational age of newborns classified as term and the success of breastfeeding in babies born by elective cesarean section. Also, to analyze how the variability of gestational age within the term influences breastfeeding. Materials and Methods: Retrospective study of a cohort, which included full-term newborns and their mothers, whose deliveries occurred by elective cesarean section. Among the inclusion criteria are delivery due to elective cesarean section and minimum gestational age of 37 weeks. The database consisted of medical birth information and interviews with mothers. Results: This study included 954 full-term newborns born by elective cesarean section. Exclusive breastfeeding at 3 months and being breastfed at 6 months showed a statistically significant association in the correlation with the variability of gestational age. There was a statistically significant association between exclusive breastfeeding at 3 months and breastfeeding at 6 months in the correlation between early term and full term. The trend test showed a significant progressive in the breastfeeding curve versus gestational age. Conclusion: Full-term newborns show better results of exclusive breastfeeding at 3 months and continued breastfeeding at 6 months, compared with those born at early term. Gestational age, even in term, has an influence on the success of breastfeeding in newborns undergoing elective cesarean delivery.

Under-Five Mortality in Sierra Leone and Possible Associated Factors: Evidence from the 2019 Demographic and Health Survey

High under-five mortality rate remains one of the public health challenges, especially in sub-Saharans Africa, accounting for more than half of all global cases. Sierra Leone was and still one of the countries with the highest under-five mortality rate. Using the latest 2019 SLDHS data, we investigated factors associated with under-five mortality in Sierra Leone. A total of 9771 mothers aged 15-49 years in the country were interviewed and included in the analysis. The dependent variable is child status (dead=1; alive=0). A total of 871 (9%) children died before their fifth birthday. Maternal age of 20-24 years (AOR=0.46; CI=0.33-0.64; P<0.001) up to 40-44 years (AOR=0.43; CI=0.27-0.7; P=0.001), currently breastfeeding (AOR=0.20; CI=0.17-0.24; P<0.001), maternal media exposure and usage of reading newspapers/magazines less than once a week (AOR=0.48; CI=0.28-0.85; P=0.011) were more likely to enhance child survivability through their fifth birthday. Also, the child sex being female (AOR=0.68; CI=0.59-0.79) was more likely to survive under-five mortality compared to their male counterpart. On the other hand, mothers who listened to radio at least once a week (AOR=1.31; CI=1.08-1.59; P=0.007) watched television less than once a week (AOR=1.48; CI=1.16-1.90), had two (AOR=3.4, CI=2.78-4.16; P<0.001) or three and above birth (AOR=8.11; CI=6.07-10.83; P<0.001) in five years, had multiple birth children (AOR=1.41; CI=1.08-1.86) and very small-sized child at birth (AOR= 1.95; CI=1.41-2.70) were more likely to lose their children below the age of five years. The factors contributing to under-five mortality in Sierra Leone are critical to ensuring child survival and improving maternal health. Breastfeeding, maternal age, media exposure, child's sex, multiple birth type, very small-sized child and the total number of births in five years were significant drivers of under-five mortality. The result affirms the need for attention to be focused on enhancing the survival rate of under-five children in Sierra Leone.

Recurrent Acute Otitis Media Environmental Risk Factors: A Literature Review from the Microbiota Point of View

Acute otitis media (AOM) constitutes a multifactorial disease, as several host and environmental factors contribute to its occurrence. Prevention of AOM represents one of the most important goals in pediatrics, both in developing countries, in which complications, mortality, and deafness remain possible consequences of the disease, compared to in developed countries, in which this condition has an important burden in terms of medical, social, and economical implications. The strategies for AOM prevention are based on reducing the burden of risk factors, through the application of behavioral, environmental, and therapeutic interventions. The introduction of culture-independent techniques has allowed high-throughput investigation of entire bacterial communities, providing novel insights into the pathogenesis of middle ear diseases through the identification of potential protective bacteria. The upper respiratory tract (URT) is a pivotal region in AOM pathogenesis, as it could act as a source of pathogens than of protective microorganisms for the middle ear (ME). Due to its direct connection with the external ambient, the URT is particularly exposed to the influence of environmental agents. The aim of this review was to evaluate AOM environmental risk factors and their impact on URT microbial communities, and to investigate AOM pathogenesis from the microbiota perspective.

Technical Report: Breastfeeding and the Use of Human Milk

Breastfeeding and human milk are the normative standards for infant feeding and nutrition. The short- and long-term medical and neurodevelopmental advantages of breastfeeding make breastfeeding or the provision of human milk a public health imperative. The American Academy of Pediatrics (AAP) recommends exclusive breastfeeding for approximately 6 months after birth. Furthermore, the AAP supports continued breastfeeding, along with appropriate complementary foods introduced at about 6 months, as long as mutually desired by mother and child for 2 years or beyond. These recommendations are consistent with those of the World Health Organization (WHO). Medical contraindications to breastfeeding are rare. The AAP recommends that birth hospitals or centers implement maternity care practices shown to improve breastfeeding initiation, duration, and exclusivity. The Centers for Disease Control and Prevention and The Joint Commission monitor breastfeeding practices in United States hospitals. Pediatricians play a critical role in hospitals, their practices, and communities as advocates of breastfeeding and, thus, need to be trained about the benefits of breastfeeding for mothers and children and in managing breastfeeding. Efforts to improve breastfeeding rates must acknowledge existing disparities and the impact of racism in promoting equity in breastfeeding education, support, and services.

Breastfeeding initiation and duration and acute otitis media among children less than two years of age in Jordan: results from a case–control study

Background

Acute otitis media (AOM) is one of the most common infectious diseases that affects children. Breastfeeding has been linked to a lower risk of AOM in the first three years of childhood. The aim of this study was to identify the association between exclusive breastfeeding and the development of acute otitis media (AOM) and investigate the influence of breastfeeding duration on the presence of AOM.

Methods

In a retrospective case–control study, a sample of 98 children (cases) who were diagnosed with AOM and 98 children (controls) who were not diagnosed with AOM and were younger than two years old were selected from the Jordan University Hospital. Medical records were used to identify children with AOM. For both the case and control groups, the children’s mothers completed a self-administered questionnaire about factors linked to the incidence of AOM.The type of feeding and the duration of breastfeeding were assessed using a validated questionnaire.

Results

The data indicated that among children who developed AOM, 23.5%were artificiallyfed, while 22.4% and 13.3% were exclusively breastfed for 3 months and 6 months, respectively. Approximately 70.7% of the children without AOM were exclusively breastfed for 6 months, compared with only 29.3% of the children without AOM who were exclusively breastfed for 3 months.Logistic regression revealed that nonexclusive breastfeeding, exclusive breastfeeding for 3 months, and exclusive breastfeeding for 6 months were protective factors against AOM (OR = 0.23, 0.18, and 0.25, respectively; P < 0.05). A short duration of exclusive breastfeeding was considered a risk factor for the development of AOM (OR = 1.7, P < 0.05).

Conclusions

The escalation of AOM is tightly connected to the early introduction of formula feeding in the first six months of life. Breastfeeding had a protective impact on the occurrence of AOM. Understanding factors that are associated with the occurrence of AOM in children may support the role of public health institutions and primary health care in the prevention and reduction of AOM episodes and the need for national health strategies to promote breastfeeding.

Exclusive breastmilk pumping: A concept analysis

Aim

To analyze and examine the concept of exclusive breast pumping (EP).

Background

Breastmilk is the ideal nutrition for infants, yet when breastfeeding is unsuccessful, parents resort to informal breastmilk sharing, artificial formula feeding, or EP. A growing proportion of families exclusively pump yet they often receive guidance from social media rather than healthcare providers because healthcare providers are uninformed about this feeding method.

Data Source

Cumulative Index of Nursing and Allied Health Literature, PubMed, and Google Scholar databases were searched using the following keywords: human milk express*, breast express*, breast milk express, breastmilk express*, exclusive pump, exclusive breast pumping, and exclusive expression.

Review Methods

Concept analysis design using Walker and Avant's method.

Results

Three defining attributes of (1) absence of direct breastfeeding, (2) breastmilk expression, (3) and an enduring infant feeding pattern of feeding expressed breastmilk only via a bottle were identified. All three attributes are required to confirm the presence of the concept of exclusive pumping. Definitions, antecedents, consequences, and empirical referents are described. Model and contrary cases are discussed.

Conclusion

This exclusive pumping concept analysis allows for consistency in terminology in practice and research. EP is a feeding method which can increase the proportion of infants who are fed breastmilk and may reduce the risks that arise from artificial formula feeding.

Effects of Early Weaning Associated with Alimentary Stress on Emotional and Feeding Behavior of Female Adult Wistar Rats

Maternal lactation proves crucial for mammals’ nutrition during their early development, influencing the development of adult physiological mechanisms. Its premature termination has been associated with several disorders, but these have been primarily documented in males, when they are most prevalent in women. Therefore, we subjected adult female Wistar rats to Early Weaning through maternal separation at age 15 days to acute alimentary stress in the form of visual and olfactory exposition to a cafeteria diet sans consumption for 22 days. We measured standard diet intake and water intake daily and cafeteria diet intake every 7 days. Additionally, we evaluated anxiety using the elevated plus maze and measured body weight in similar intervals. Results showed less consumption of the cafeteria diet among Early Weaning rats on day 2 and more time spent in the maze’s central area by the Early Weaning rats during the basal evaluation and in the maze’s open arms by control rats on day 7 when compared to the same group’s basal time. No other significant differences were found. These results show the importance of determining the impact that female steroidal gonadal hormones such as estradiol have upon feeding behavior and anxiety and determining to what degree these parameters are influenced by hormonal action.

Mothers' hygiene experiences in confinement centres: A cohort study

Introduction

Ethnic Malaysian Chinese used to observe the 1-month postpartum confinement period at home and many families would engage a traditional postpartum carer to help care for the mother and newborn. A recent trend has been the development of confinement centres (CCs) which are private non-healthcare establishments run by staff not trained in health care. Concerns about hygiene in CCs arose after infections were reported. We describe the practice of hand hygiene observed in CCs, the availability of resources for hygiene, and the prevalence of health-related problems in CCs.

Methods

This is a cohort study of ethnic Chinese mothers intending to breastfeed their healthy infants. They were recruited post-delivery along with a comparison group who planned to spend their confinement period at home. After their 1-month confinement period, they were contacted for a structured telephone interview about their experience. To avoid any alteration in behaviour, mothers were not told at recruitment that they had to observe hygiene practices. Multiple logistic regression was used to assess the effect of place of confinement on rates of infant health problems.

Results

Of 187 mothers, 88(47%) went to 27 different CCs while 99(53%) stayed at home. Response rates for the 1-month interviews were 88%(CC) versus 97%(home). Mothers in CC group stayed in one to four-bedded rooms and 92% of them had their baby sleeping separately in a common nursery described to have up to 17 babies at a time; 74% of them spent less than six hours a day with their babies; 43% noticed that CC staff had inadequate hand hygiene practices; 66% reported no hand basins in their rooms; 30% reported no soap at hand basins; 28% reported inexperienced or inadequate staff and 4% reported baby item sharing. Among the mothers staying at home, 35% employed a traditional postpartum carer for her baby; 32% did not room-in with their babies, but only 11% spent less than 6 hours a day with their babies. Of mothers who employed traditional postpartum carers, 32% did not know if their carer washed hands after changing diapers and 18% reported that their carer did not. Health problems that were probably related to infection (HPRI) like fever and cough were similar between the groups: 14%(CC) versus 14%(home) (p = 0.86). Multiple logistic regression did not show that CCs were a factor for HPRI: aOR 1.28 (95% CI 0.36 to 4.49). Three mothers reported events that could indicate transmission of infection in CCs.

Conclusion

We found unsatisfactory hygiene practices in CCs as reported by mothers who spent their confinement period there. Although we were not able to establish any direct evidence of infection transmission but based on reports given by the mothers in this study, it is likely to be happening. Therefore, future studies, including intervention studies, are urgently needed to establish an appropriate hygiene standard in CCs as well as the best method to implement this standard. Training CC staff with hygiene knowledge so that they can be empowered to contribute to the development of these standards would be important.

Mixed Milk Feeding: A New Approach to Describe Feeding Patterns in the First Year of Life Based on Individual Participant Data from Two Randomised Controlled Trials

'Mixed Milk Feeding' (MMF), whereby infants are fed with both breastmilk and infant formula during the same period, is a common feeding practice. Despite its high prevalence, knowledge regarding MMF practices and their association with (health) outcomes is limited, potentially because MMF behaviours are highly variable and difficult to standardise longitudinally. In this paper, we applied a statistical clustering algorithm on individual infant feeding data collected over the first year of life from two clinical trials: 'TEMPO' (n = 855) and 'Venus' (n = 539); these studies were conducted in different years and world regions. In TEMPO, more than half of infants were MMF. Four distinct MMF clusters were identified: early exclusive formula feeding (32%), later exclusive formula feeding (25%), long-term MMF (21%), and mostly breastfeeding (22%). The same method applied to 'Venus' resulted in comparable clusters, building trust in the robustness of the cluster approach. These results demonstrate that distinct MMF patterns can be identified, which may be applicable to diverse populations. These insights could support the design of future research studying the impact of infant feeding patterns on health outcomes. To standardise this in future research, it is important to establish a unified definition of MMF.

Quantification and progress over time of specific antibodies against SARS-CoV-2 in breast milk of lactating women vaccinated with BNT162b2 Pfizer-BioNTech COVID-19 vaccine (LacCOVID)

Background

Several observational studies demonstrated the passage of postvaccine antibodies through breast milk in women vaccinated against coronavirus disease 2019 (COVID-19), mostly with messenger RNA (mRNA)–based vaccines, but lacked long-term data.

Methods

A 6-month prospective cohort study was performed to determine severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine–induced antibody levels in the breast milk of 33 lactating healthcare workers at different timepoints after mRNA BNT162b2 Pfizer-BioNTech COVID-19 vaccination. Moreover, we examined the correlation of SARS-CoV-2 antibody levels between serum and breast milk, adverse events related to vaccination, and rate of SARS-CoV-2 infections.

Results

Mothers’ median age was 38 (interquartile range [IQR], 36–39) years and 15 (IQR, 10–22) months for infants. Median (IQR) SARS-CoV-2 immunoglobulin G (IgG) spike protein subunit S1 (S1) vaccine–induced levels at different timepoints for serum–milk pairs were 519 (234–937) to 1 (0–2.9) arbitrary units (AU)/mL at 2 weeks after first dose and 18 644 (9923–29 264) to 78 (33.7–128), 12 478 (6870–20 801) to 50.4 (24.3–104), 4094 (2413–8480) to 19.9 (10.8–51.9), 1350 (831–2298) to 8.9 (7.8–31.5) AU/mL at 2, 4, 12 and 24 weeks after second dose, respectively. We observed a positive correlation of antibody levels between serum and breast milk, no serious adverse events related to vaccination, and 2 (6%) COVID-19 vaccine breakthrough infections.

Conclusions

Women vaccinated with Pfizer-BioNTech transmit antibodies into breast milk with a positive correlation with serum levels. Both decreased over time in a 6-month follow-up.

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.

Breastfeeding on childhood obesity in children were large-for-gestational age: retrospective study from birth to 4 years

Our aim was to assess effects of breast-feeding (BF) in the association between large-for-gestational age (LGA) and body mass index (BMI) trajectories on childhood overweight from 1 to 4 years old. A total of 1649 healthcare records of mother–child pairs had detailed records of feeding practices and were included in this retrospective cohort study. Data were available in Medical Birth Registry of Xiamen between January 2011 and March 2018. Linear and logistic regression models were used to access the difference between BF and no-BF group. For offspring were LGA and BF was significantly associated with a lower BMI Z-score from 1 to 4 years old after adjustment confounders in Model 1 to 3 [difference in BMI Z-score in Model 1: estimated β: −0.07 [95%CI: −0.13 to −0.01]; Model 2: estimated β: −0.07 (−0.13 to −0.004); Model 3: estimated β: −0.06 (−0.12 to −0.001); P = 0.0221, 0.0371, 0.0471]. A significantly lower risk of childhood overweight was observed in Model 1 [odd ratio (OR): 0.85 (95%CI, 0.73 to 1.00)], P = 0.0475) with adjustment for maternal pre-pregnancy BMI. Furthermore, Model 2 and Model 3 showed LGA-BF infants had a lower risk for childhood overweight then LGA-no-BF infants [OR: 0.87 and 0.87 (95%CI, 0.73 to 1.03; 0.74 to 1.03)], however, there was no statistical significance (P = 0.1099, and 0.1125)]. BF is inversely related to BMI Z-score and risk for overweight in children were LGA from 1 to 4 years old. Adjustment for maternal pre-pregnancy BMI, the protective association between BF and childhood overweight was more significant.

Exclusive Breastfeeding and Vitamin D Supplementation: A Positive Synergistic Effect on Prevention of Childhood Infections?

Human milk is the best food for infants. Breastfeeding has been associated with a reduced risk of viral and bacterial infections. Breast milk contains the perfect amount of nutrients needed to promote infant growth, except for vitamin D. Vitamin D is crucial for calcium metabolism and bone health, and it also has extra-skeletal actions, involving innate and adaptive immunity. As exclusive breastfeeding is a risk factor for vitamin D deficiency, infants should be supplemented with vitamin D at least during the first year. The promotion of breastfeeding and vitamin D supplementation represents an important objective of public health.

Breast Milk: A Meal Worth Having

A mother is gifted with breast milk, the natural source of nutrition for her infant. In addition to the wealth of macro and micro-nutrients, human milk also contains many microorganisms, few of which originate from the mother, while others are acquired from the mouth of the infant and the surroundings. Among these microbes, the most commonly residing bacteria are Staphylococci, Streptococci, Lactobacilli and Bifidobacteria. These microorganisms initiate and help the development of the milk microbiota as well as the microbiota of the gastrointestinal tract in infants, and contribute to developing immune regulatory factors such as cytokines, growth factors, lactoferrin among others. These factors play an important role in reducing the risk of developing chronic diseases like type 2 diabetes, asthma and others later in life. In this review, we will summarize the known benefits of breastfeeding and highlight the role of the breast milk microbiota and its cross-talk with the immune system in breastfed babies during the early years of life.

Association between maternal insecticide use and otitis media in one-year-old children in the Japan Environment and Children's Study

Otitis media (OM) is common among young children and is related to hearing loss. We investigated the association between maternal insecticide use, from conception to the first and second/third trimesters, and OM events in children in the first year of age. Data from Japan Environment and Children's Study were used in this prospective cohort study. Characteristics of patients with and without history of OM during the first year of age were compared. The association between history of OM in the first year and insecticide use was evaluated using logistic regression analysis. The study enrolled 98,255 infants. There was no significant difference in the frequency of insecticide use between groups. Insecticide use of more than once a week from conception to the first trimester significantly increased the occurrence of OM in children in the first year (odds ratio [OR] = 1.30, 95% confidence interval [CI] 1.01–1.67). The association between OM in the first year and insecticide use from conception to the first trimester was only significant in the group without daycare attendance (OR 1.76, 95% CI 1.30–2.38). Maternal insecticide use more than once a week from conception to the first trimester significantly increased OM risk in offspring without daycare attendance.

Increasing the exclusive breastfeeding rate in a private hospital in UAE through quality improvement initiatives

BACKGROUND

Mother's milk is the best, and ideal method for infant feeding. We found that this practice was not being followed in our hospital. A survey was conducted in the unit with regards to breastfeeding practices which revealed that most babies who were discharged from our nursery were on formula supplements. Our goal was to improve established breastfeeding rates in the unit by increasing the number of full-term healthy babies who were discharged on exclusive Breastfeeding.

METHOD

A project team was formed, and data were collected through direct observations and direct interviews with postnatal mothers. Exclusive Breastfeeding at discharge was defined as a baby being fully on breastfeed with no additional formula supplements for at least 12 hours prior to discharge. The primary outcome was to increase the percentage of babies being discharged on exclusive Breastfeeding. We used the FOCUS PDCA model to measure improvements and 8 PDCA cycles of 4 weeks duration were implemented to test the changes.

RESULTS

The interventions we put in place led to a considerable nine times overall improvement in the established breastfeeding rates. Among all the interventions, the most promising results were observed during the PDCA cycles involving staff education, the introduction of antenatal classes for mothers, skin to skin contact and rooming in.

CONCLUSION

Breastfeeding rates in the private sector with nursery services can be improved by reinforcing breastfeeding education for mothers in addition to training the maternal care staff, empowering them to promote and assist in breastfeeding.

Breastfeeding and respiratory, ear and gastro-intestinal infections, in children, under the age of one year, admitted through the paediatric emergency departments of five hospitals

BACKGROUND

Breastfeeding is a protective factor against respiratory and intestinal infections in developing countries. In developed countries, proof of this protection is more difficult to show. The objective of the study is to compare the proportion of children breastfed during their first year in groups of children with infectious pathologies supposedly prevented by breastfeeding and children free of these infectious pathologies.

METHOD

Questionnaires about diet, socio-demographic data and the motive for consultation were given to the parents upon arrival in the paediatric emergency departments of 5 hospitals located in Pays de Loire (France) in 2018 and 2019. Children with lower respiratory tract infections, acute gastroenteritis and acute otitis media were included in the case group (A), children admitted for other reasons were included in the same control group (B). Breastfeeding was classified as exclusive or partial.

RESULTS

During the study period, 741 infants were included, of which 266 (35.9%) in group A. In this group, children were significantly less likely to have been breastfed at the time of admission than children in group B: for example, for children under 6 months, 23.3% were currently breastfed in group A, vs. 36.6% (weaned BF or formula diet) in group B [OR = 0.53 (0.34-0.82); p = 0.004]. Similar results were found at 9 and 12 months. After taking into account the age of the patients, the same results were confirmed with an aOR = 0.60 (0.38-0.94) (p = 0.02) at 6 months, but with when considering six variables six variables, aOR was not significative aOR = 0.65 (0.40-1.05); p = 0.08), meaning that factors such as the childcare out of home, socio-professional categories, and the pacifier decrease the protective effect of breastfeeding. Sensitivity analyses (age-matching, analysis by type of infection) showed the same protection effect provided by breastfeeding when it was pursued for at least 6 months and also that the protective effect of breastfeeding is especially true against gastro-enteritis.

CONCLUSION

Breastfeeding is a protective factor against respiratory, gastrointestinal and ear infections when pursued at least 6 months after birth. Other factors such as collective childcare, pacifiers and low parental professional status can reduce the protective effect of breastfeeding.

Associations of Human Milk Oligosaccharides With Otitis Media and Lower and Upper Respiratory Tract Infections up to 2 Years: The Ulm SPATZ Health Study

Background: Human milk oligosaccharides (HMOs) support and concurrently shape the neonatal immune system through various mechanisms. Thereby, they may contribute to lower incidence of infections in infants. However, there is limited evidence on the role of individual HMOs in the risk of otitis media (OM), as well as lower and upper respiratory tract infections (LRTI and URTI, respectively) in children up to 2 years.

Objective: To investigate whether individual HMO concentrations measured at 6 weeks of lactation were associated with risk of OM, LRTI or URTI up to 2 years in breastfed infants. Associations with OM, LRTI and URTI were determined for the most prominent human milk oligosaccharides including 13 neutral, partly isomeric structures (trioses up to hexaoses), two acidic trioses, and lactose.

Design: HMO measurements and physician reported data on infections were available from human milk samples collected at 6 weeks postpartum (n = 667). Associations of HMOs with infections were assessed in crude and adjusted models using modified Poisson regression.

Results: Absolute concentrations (median [min, max], in g/L) of 2′-fucosyllactose (2′-FL) tended (p = 0.04) to be lower, while lacto-N-tetraose (LNT) was higher in the milk for infants with OM in the 1st year of life (p = 0.0046). In the milk of secretor mothers, LNT was significantly higher in the milk for infants with OM (RR [95% CI]: 0.98 [0.15, 2.60]) compared to infants without OM (RR [95% CI]: 0.76 [0.14, 2.90]) at 1 year (p = 0.0019). No statistically significant milk group differences and associations were observed for OM, LRTI, and URTI (p > 0.0031).

Conclusion: Our findings suggest that neither prominent neutral individual HMOs (ranging from 2′-FL to LNDFHs) nor acidic human milk sialyllactoses or lactose are significantly associated with a reduced or increased risk of infections in infants up to 2 years of age. Further research is needed to determine whether specific HMOs could potentially reduce the incidence or alleviate the course of distinct infections in early life.
