Factors Associated with Supplemental Formula Feeding of Breastfeeding Infants During Postpartum Hospital Stay

Growth and gastrointestinal tolerance of healthy formula-fed infants: a multicentre, prospective observational study

BACKGROUND

Infant formula with human milk oligosaccharides (HMOs) and increased β-palmitate mimics breast milk nutritional composition and clinical benefits. We aimed to assess formula-fed infant growth, gastrointestinal tolerance, infections, and parental satisfaction with a partly fermented infant formula with an improved lipid profile (enriched with β-palmitate and docosahexaenoic/arachidonic acid) and short and long-chain oligosaccharides (scGOS/lcFOS [9:1]) and HMOs.

METHODS

A prospective descriptive observational study in healthy infants with formula feeding or breastfeeding (reference population) was conducted in six Spanish primary care centres following routine clinical practice. In the first, second and fourth month of life visits sociodemographic, clinical, and anthropometric variables (weight, length, head circumference), stool consistency (Brussels Infant and Toddler Stool Scale [BITSS]), gastrointestinal symptoms, infections incidence and associated healthcare resource utilisation, and caregivers' satisfaction with formula were collected. A descriptive statistical analysis was performed (STATA-v.14). Growth was estimated as the mean (standard deviation) increase in the anthropometric variables and z-scores.

RESULTS

A total of 61 formula-fed and 65 breastfed infants were included in the study (50.8% male). The average increase in weight, length and head circumference in the formula feeding and in the breastfeeding groups from the first to the fourth month of life was 2,566 (496) g, 9.7 (1.7) cm and 4.4 (1.0) cm, and 2,571 (702) g, 9.8 (1.8) cm and 4.4 (1.1) cm, respectively. The weight z-score was -0.1 (0.7) for formula-fed and 0.1 (1.1) for breastfed infants. In all visits, more than 88% of infants had loose/watery stools and most infants suffered gastrointestinal symptoms with low/medium frequency. In the fourth month of life visit, 16 (26.2%) formula-fed and 16 (24.6%) breastfed infants had infections, mainly respiratory, with 16% of formula-fed and 12% of breastfed infants requiring treatment. Most formula-feeding caregivers had a good/very good opinion of formula (85.2%). 75.4% infants drank the whole feeding bottle.

CONCLUSIONS

The growth, gastrointestinal tolerance, and incidence of infections of healthy formula-fed infants during the first four months of life were appropriate and in line with WHO standards. Formula feeding caregivers were satisfied with this partly fermented infant formula with an improved lipid profile and oligosaccharides.

Prevalence of and factors associated with formula feeding among mothers with infants 0-6 months of age in Ethiopia: a systematic review and meta-analysis

CONTEXT

Inconsistent results have been reported regarding the prevalence of and factors associated with formula feeding in Ethiopia.

OBJECTIVE

This study aimed to determine the pooled prevalence of and factors associated with formula feeding among mothers with infants 0-6 months of age in Ethiopia.

DATA SOURCES

A comprehensive systematic search was conducted across 3 databases (PubMed, EMBASE, and ScienceDirect) and the Google Scholar search engine to identify relevant studies published up to April 2, 2024.

DATA EXTRACTION

After assessing the quality of each study using the Joanna Briggs Institute Critical Appraisal Checklist for Prevalence Studies, data were independently extracted by 2 authors using pre-designed forms in an Excel spreadsheet. Any disagreements were resolved through discussion and consultation with additional authors.

DATA ANALYSIS

Statistical heterogeneity across studies was assessed using the I2 statistic. A random-effects meta-analysis was used to pool the proportions, due to high heterogeneity, while a fixed-effect meta-analysis was used to pool associated factors with low heterogeneity. A sensitivity analysis was performed to assess the potential impact of outlier studies on the overall estimates. Five studies, with a combined sample size of 2344 participants, were included. The pooled prevalence of formula feeding was 34.0% (95% CI: 23.0%, 44.0%). Factors significantly associated with formula feeding included cesarean delivery (POR [pooled odds ratio] = 4.72, 95% CI: 3.32, 6.71) compared with vaginal delivery, a positive attitude toward formula feeding (POR = 2.26, 95% CI: 1.45, 3.53) compared with a negative attitude, initiation of breastfeeding more than 1 hour after delivery (POR = 2.27, 95% CI: 1.25, 4.13) compared with initiation within 1 hour, and receiving information about formula feeding from friends or family (POR = 2.47, 95% CI: 1.46, 4.20) compared with receiving information from health-care professionals.

CONCLUSION

The prevalence of formula feeding in Ethiopia is significant. Cesarean delivery, a positive attitude toward formula feeding, late initiation of breastfeeding, and receiving formula feeding-related information from friends and family were positively associated with formula feeding. Given these findings, the authors recommend that public health interventions in Ethiopia target these key determinants to decrease the high prevalence of formula feeding practices observed in the country. Strategies addressing factors such as promoting vaginal delivery, improving attitudes toward breastfeeding, encouraging early breastfeeding initiation, and limiting the influence of social networks on formula-feeding decisions may be beneficial.

Why do mothers mix milk feed their infants? Results from a systematic review

CONTEXT

Combining or supplementing breastfeeding with formula feeding, also called mixed milk feeding (MMF), is a common infant feeding practice. However, there is no well-established MMF evidence-base for informing and guiding parents. A better understanding of the reasons why mothers practice MMF may facilitate identification of efficient strategies for supporting exclusive breastfeeding, and/or opportunities to prolong breastfeeding, at least partially.

OBJECTIVE

An updated systematic literature review was undertaken with the primary aim of gaining a deeper understanding of the reasons why mothers choose MMF.

DATA SOURCES

Six databases were searched for relevant articles published in English from January 2012 to January 2022.

DATA EXTRACTION

Two reviewers independently performed the screenings and data extraction, and any differences were resolved by a third reviewer. Data from 138 articles were included, 90 of which contained data on MMF reasons/drivers, and 60 contained data on infant age and/or maternal demographic factors associated with MMF.

DATA ANALYSIS

A total of 13 different unique MMF drivers/reasons were identified and categorized according to whether the drivers/reasons related to perceived choice, necessity, or pressure. Risk of bias was evaluated using the Quality Assessment Tool of Diverse Studies and the JBI Systematic Reviews tool. Several different terms were used to describe and classify MMF across the studies. The most commonly reported reasons for MMF were related to a perception of necessity (39% of drivers, eg, concerns about infant's hunger/perceived breast milk insufficiency or breastfeeding difficulties), followed by drivers associated with perceived choice (34%; eg, having more flexibility) and perceived pressure (25%; eg, returning to work or healthcare professionals' advice). This was particularly true for infants aged 3 months or younger.

CONCLUSION

The key global drivers for MMF and their distribution across infant age and regions were identified and described, providing opportunities for the provision of optimal breastfeeding support. A unified definition of MMF is needed in order to enable more comparable and standardized research.

Infant formula feeding and associated factors in Debre Berhan City: A community based cross-sectional study

Introduction

Globally, there is rising concern over the growing reliance on breast milk substitutes (BMSs). However, limited studies have been conducted to explore this issue in Ethiopia.

Objective

To assess infant formula feeding and associated factors among mothers of infants aged 0-6 months in Debre Berhan City, 2023.

Methods and materials

This cross-sectional study used a multistage sampling technique to select 656 mothers residing in Debre Berhan city. The data was collected through face-to-face interviews using a semi-structured questionnaire. Bivariable and multivariable logistic regression models were employed to identify the factors associated with infant formula feeding. The findings are then presented as frequencies, percentages, and odds ratios.

Results

The prevalence of infant formula feeding in Debre Berhan city was 39.7 %. In addition, having a female child [AOR = 1.75, 95 % CI: 1.08-2.86], receiving a college education or higher [AOR = 5.79, 95 % CI: 2.38-14.08], being in the age category of 25-34 [AOR = 2.38, 95 % CI: 1.10-5.15] or 35-45 [AOR = 3.43, 95 % CI: 1.35-8.69], being a prime mother [AOR = 1.81, 95 % CI: 1.12-2.94], receiving breastfeeding advice [AOR = 4.64, 95 % CI: 2.78-7.75], delivering via a C-section [AOR = 5.39, 95 % CI: 2.54-11.42], initiating breastfeeding late [AOR = 2.26, (95 % CI: 1.41-3.64)], or being unaware of the risks associated with infant formula feeding [AOR = 5.48, 95 % CI: 3.20-9.39] were the factors that drove mothers towards infant formula feeding.

Conclusion

In Debre Berhan city, the prevalence of infant formula feeding was high. Fortunately, with appropriate interventions, most of the factors that led to infant formula feeding could be effectively addressed.

Investigating factors influencing decision-making around use of breastmilk substitutes by health care professionals: a qualitative study

BACKGROUND

Breastfeeding is recognized as the gold standard of infant feeding and nutrition. The World Health Organization recommends exclusive breastfeeding (EBF) of infants for the first 6 months of life. A variety of factors may impact breastfeeding practices in-hospital which may continue after hospital discharge, such as the use of breastmilk substitutes (BMS). The Baby-Friendly Initiative (BFI), which aims to promote and support breastfeeding practices, established a target rate of 75% for EBF from birth to hospital discharge. Currently, this target is not being met at The Ottawa Hospital (TOH), indicating there is room for improvement in EBF rates. The purpose of this study is to explore health care professionals (HCP) decision-making around use of BMS and identify factors that drive the use of BMS with and without medical indications.

METHODS

In this qualitative study, semi-structured interviews were conducted with HCPs within TOH from January to June 2022. All participants had experience in maternity or postpartum care and were probed on factors influencing use of BMS at this institution. Interview transcripts were coded using an inductive approach.

RESULTS

A total of 18 HCPs were interviewed including physicians, midwives, lactation consultants, and registered nurses. Multilevel barriers influencing the use of BMS were categorized into patient, HCP, and institution-level factors. Subthemes that emerged ranged from parental preferences, training differences amongst HCPs, to budget and staffing issues. Over half of HCPs were prepared to answer questions on EBF and were familiar with the BFI. Although most were supportive of this institution receiving BFI designation, a few providers raised concerns of its impact on parents who would like to supplement.

CONCLUSIONS

Several modifiable factors influencing decision-making for use of BMS were identified. These findings will be used to inform unit leads, help identify effective strategies to address modifiable barriers, and develop tailored breastfeeding supports to improve EBF rates.

Reported Adherence to the 10 Steps to Successful Breastfeeding Is Higher Among Baby-Friendly Hospitals

OBJECTIVE

Quantify and compare reported breastfeeding support practices in the Baby-Friendly Hospital Initiative (BFHI) and non-BFHI facilities.

DESIGN

Cross-sectional survey.

SETTING

Regions across the US.

PARTICIPANTS

Two hundred and eighty-six facilities (110 BFHI and 176 non-BFHI) selected by a stratified (by hospital size) random sample of 50% BFHI and 50% non-BFHI facilities.

INTERVENTION

Emailed survey Fall 2019 through Spring 2020.

MAIN OUTCOME MEASURE

Reported adherence to the 10 Steps to Successful Breastfeeding.

ANALYSIS

Wilcoxon rank sum test with continuity correction, Pearson chi-square test of independence, and Fisher's exact test.

RESULTS

Baby-Friendly Hospital Initiative facilities were more likely to report adherence to the 10 Steps to Successful Breastfeeding. Only 2 of the reported steps were not significantly different: immediate postnatal care and responsive feeding.

CONCLUSIONS AND IMPLICATIONS

This research supports breastfeeding support interventions within hospitals as both BFHI and non-BFHI facilities have room for improvement. Interventions targeting non-BFHI facilities are an opportunity to close the disparity in breastfeeding care.

'She was hungry'-Croatian mothers' reasons for supplementing their healthy, term babies with formula during the birth hospitalisation

AIM

To explore why Croatian mothers request formula for their healthy, term newborn infants during the postnatal hospital stay.

METHODS

Four focus groups discussions were conducted with a total of 25 women who gave birth to healthy newborn infants, between May and June 2021 in Split, Croatia. A homogenous, non-random purposive sampling technique was used. The semi-structured interview schedule contained 15 open-ended questions. Reflexive thematic analysis was applied.

RESULTS

Three themes were generated. The first theme fear of hunger referred to the mothers' fears arising from difficulties in interpreting newborn infant behaviour and finding solace in giving formula. The second theme too little support-too late reflected participants' unrealised expectations of hospital staff. The third theme non-supportive communication addressed mother's need for empathy during the postpartum hospital stay.

CONCLUSION

Croatian mothers want to breastfeed, but often feel unsupported in doing so in the maternity hospital setting. Antenatal education of expectant mothers and training of maternity staff in breastfeeding counselling, with a strong emphasis on communication skills, as well as employment of International Board Certified Lactation Consultants and/or volunteer breastfeeding counsellors, were perceived by participants as a way to decrease mothers' requests for formula for their healthy, newborn infants.

Formula feeding and associated factors among mothers with infants 0-6 months old in Mettu Town, Southwest Ethiopia

Adequate nutrition during infancy is essential for children's normal development and well-being. However, the duration of breastfeeding has been declining and is being replaced by formula feeding, particularly in the urban communities of developing countries, including Ethiopia. Hence, this study aimed to assess formula feeding and its associated factors, as relatively little information is available regarding this problem in Ethiopia, particularly in Mettu Town. A community-based cross-sectional study was conducted in Mettu Town from May 17 to July 1, 2021, among 366 mothers with infants 0-6 months old. A simple random sampling technique was used in this study. Pre-tested semi-structured questionnaires were used to collect the data. Descriptive statistics and multivariable logistic regression were performed, and variables with a p-value <0.05 in the final model were declared statistically significant with formula feeding found to be 28.4% [95% CI: (24.0-33.0)]. Primiparity [AOR = 3.27, 95% CI: (1.71-6.27)], cesarean delivery [AOR = 2.62, 95% CI: (1.28-5.35)], initiation of breastfeeding after 24 h [AOR = 3.5, 95% CI: (1.74-10.0)], employed mothers [AOR = 2.4, 95% CI: (1.29-4.19)], positive attitude toward formula feeding [AOR = 2.4, 95% CI: (1.29-4.19)], and poor knowledge of formula feeding [AOR = 2.6, 95% CI (1.49-4.74)] were factors significantly associated with formula feeding. Almost one-third of the mothers were formula feeding their infants. Primiparity, maternal employment, initiation of breast milk after 24 h, cesarean delivery, poor maternal knowledge, and positive attitude toward formula feeding were among the contributing factors to this high formula-feeding practice. Hence, much effort should be invested in educating pregnant and lactating mothers to improve their knowledge of formula feeding while working on activities that change their attitude toward formula feeding.

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.

Factors associated with infant formula supplementation in Brazilian hospitals: a cross-sectional study

OBJECTIVE

To analyze the factors associated with infant formula supplementation in newborns referred to rooming-in in Brazilian hospitals.

METHOD

Cross-sectional study with data from 14,531 postpartum women and newborns obtained from the "Birth in Brazil" survey, conducted in 2011-2012. The analysis used a logistic regression model with a hierarchical approach.

RESULTS

In total, 21.2% newborns received infant formula during hospital stay. After adjustment, the following factors were associated with the use of infant formula: maternal age ≥ 35 years (OR = 1.51; IC95%:1.30-1.75), prenatal care in a private service (OR = 2,22; IC:1.72-2.85)/public and private service (OR = 1.67; IC:1.24-2.23), cesarean delivery (OR = 1.83; IC:1.41-2.38), multiple pregnancy (OR = 3.786; IC:2.02-7.06), non-breastfeeding in the delivery room (OR = 1.780; IC:1.43-2.21), birth in a private hospital (OR = 1.695; IC:1.02-2.79), prematurity (OR = 1.656; IC:1.32-2.06) and extremes of birth weight (< 2.500 g: OR = 2.084; IC: 1.585-2.741/ ≥4,000g: OR = 1.672; IC:1.31-2.11). Teenage age (OR = 0.651; IC:0.55-0.76), low maternal education (OR = 0.579; IC:0.43-0.77), multiparity (OR = 0.588; IC:0.510-0.678), and lower economic class (OR = 0.565; IC:0.41-0.76) significantly reduced the probability of using infant formula.

CONCLUSIONS

Of the associated factors, the authors highlight cesarean delivery and non-breastfeeding in the delivery room, showing that it is necessary to strengthen policies that encourage good practices during childbirth care in order to promote exclusive breastfeeding and protect mothers and newborns from all social classes against the misuse of infant formula.

A nation‐wide study on the common reasons for infant formula supplementation among healthy, term, breastfed infants in US hospitals

In‐hospital infant formula supplementation of breastfed infants reduces breastfeeding duration, yet little is known about common reasons for infant formula supplementation. We examined the three most common reasons for in‐hospital infant formula supplementation of healthy, term, breastfed infants in the US reported by hospital staff. Hospital data were obtained from the 2018 Maternity Practices in Infant Nutrition and Care survey (n = 2045), which is completed by hospital staff. An open‐ended question on the top three reasons for in‐hospital infant formula supplementation was analyzed using thematic qualitative analysis and the frequencies for each reason were reported. The top three most common reasons for in‐hospital infant formula supplementation reported by hospital staff included medical indications (70.0%); maternal request/preference/feelings (55.9%); lactation management‐related issues (51.3%); physical but non‐medically indicated reasons (36.1%); social influences (18.8%); perceived cultural/societal/demographic factors (8.2%) and medical staff/institutional practices (4.7%). These findings suggest that a variety of factors should be considered to address unnecessary infant formula supplementation. Lactation management support delivered in a timely and culturally sensitive manner and targeted to mother‐infant dyads with potential medical and physical indications may reduce unnecessary in‐hospital infant formula supplementation.

The three most commonly reported reasons by hospital staff for infant formula supplementation were found to be related to medical indications (70.0%); maternal request/preference/feelings about breastfeeding such as frustration or lack of confidence (55.9%); lactation management‐related issues (51.3%); physical but non‐medically indicated reasons (36.1%); social influences (18.8%); perceived cultural/societal/demographic factors (8.2%); and medical staff/institutional practices (4.7%).

Underlying many of the reported three most common reasons for infant formula supplementation is potentially lack of lactation management support that considers the social influences (e.g. from family and friends) and that is culturally relevant.

These findings suggest that a variety of factors should be considered to address unnecessary infant formula supplementation.

Efficacy of Wang Nam Yen herbal tea on human milk production: A randomized controlled trial

Background

Insufficient milk production is a common problem affecting breastfeeding women, in particular following Cesarean delivery. Wang Nam Yen herbal tea is a promising traditional Thai medicine used by postpartum women to stimulate milk production, as an alternative to pharmaceutical galactagogues. We aimed to compare the efficacy of Wang Nam Yen herbal tea, domperidone, and placebo, in increasing milk production in mothers who underwent Cesarean delivery.

Methods

Women who underwent uncomplicated cesarean delivery at Sunpasitthiprasong Hospital were randomized into three groups. The participants received the treatments daily for three consecutive days. The primary outcome was breast milk volume at 72 hours after delivery. Secondary outcomes were pregnancy and neonatal outcomes, adverse events, and participant satisfaction.

Results

Of the 1,450 pregnant women that underwent cesarean delivery, 120 women were enrolled. Their mean age and gestational ages were 28.7 years and 38.4 weeks, respectively. Breast milk volume at 72 hours postpartum was significantly different among the three groups (p = 0.030). The post hoc Bonferroni correction indicated a significant difference in breast milk volume between Wang Nam Yen herbal tea group and placebo control group (p = 0.007) while there was no difference between Wang Nam Yen herbal tea group and domperidone group (p = 0.806) and between domperidone group and placebo control group (p = 0.018). There was no difference in pregnancy and neonatal outcomes, adverse events, and participant satisfaction among the three groups.

Conclusion

Wang Nam Yen herbal tea was effective in augmenting breast milk production at 72 hours postpartum in mothers following cesarean delivery, and there was no evidence that herbal tea and domperidone differed in terms of augmenting breast milk production.

Trial registration

The study was approved by the institutional review board of Sunpasitthiprasong Hospital (No.061/2559) and was registered TCTR20170811003 with the Thai Clinical Trial Registry.

Prevalence on the complement in offering food to newborns

Abstract Objectives: to identify the prevalence and determining factors of the complements in offering food to newborns. Methods: across-sectional study nested to a cohort study that assessed newborn care in four public maternity hospitals in Natal/Brazil. Sample was composed by 415 mothers and full-term newborns, with appropriate weight for gestational age and Apgar scores in 1st and 5th minutes ≥ 7. In order to analyze the determining factors, we used Poisson’s regression. Results: from 415 newborns, 51.3% received feeding complements (57.6% in the first hour of life), of which 92% was infant formula. Only 50.7% of those complement in offering food were prescribed by physicians. Colostrum deficiency was the main reason to be indicated (33.8%). Maternal age ≤ 20 years old (PR=0.64; CI95%=0.47-0.86) and between 2030 years old (PR=0.70; CI95%=0.57-0.87)comparing to women older than 30 were shown as protective factors, while being primiparous (PR=1.37; CI95%=1.11-1.60) and had cesarean section (PR=1.2; CI95%=1.00-1.45) as risk factors. Conclusion: maternal characteristics are associated with the complement in offering food to the newborn in the first hours of life. The high prevalence shows the need for interventions that minimize the inadequate offer of infant formula and promote exclusive breastfeeding before hospital discharge.

Religious dietary rules and their potential nutritional and health consequences

BACKGROUND

The vast majority of the world population declares affiliation to a religion, predominantly Christianity and Islam. Many religions have special dietary rules, which may be more or less strictly adhered to.

METHODS

Religious food rules were collected from holy books and religious websites as well as their translation into dietary practices. The literature was searched for potential associations between these rules and potential nutritional consequences.

RESULTS

Jewish, Islamic and Indian religions support prolonged breastfeeding. Religious avoidance of alcohol is probably beneficial to health. When strictly applied, a few rules may lead to nutritional inadequacies, mainly in populations living in unfavourable socio-economic or environmental conditions. In Jewish and Muslim observants, animal slaughtering procedures may increase the risk of iron deficiency. Jews may be at risk of excess sodium intake related to home-prepared foods. A vegan diet, as observed by some believers, often by drifting from original precepts, or by some Hindus or Buddhists, may result in vitamin B12, calcium, iron, zinc, selenium and n-3 fatty acids deficiencies.

CONCLUSION

When implemented in accordance with the rules, most religious food precepts are not detrimental to health, as suggested by the fact that they have more or less been followed for millennia. Nevertheless, some practices may lead to nutritional inadequacies, such as iron, calcium, vitamin D and vitamin B12 deficiencies. Patients with low socio-economic status, children and women of childbearing age are of particular risk of such deficiencies. Being aware of them should help health professionals to take an individualized approach to decide whether to supplement or not.

A mixed methods study of perinatal sleep and breastfeeding outcomes in women at risk for postpartum depression

INTRODUCTION

Pregnant and postpartum women experience significant sleep disruption, but the role of perinatal sleep disturbances in breastfeeding is understudied.

METHODS

In this observational cohort study, we used mixed methods to examine associations between perinatal sleep and breastfeeding. Forty-eight women (mean age 28.2 ± 4.9 years) who were euthymic at enrollment but had a history of major depression (n = 43) or bipolar disorder (n = 5) had sleep recorded with wrist actigraphy. We determined feeding status through daily diaries and used semi-structured interviews to identify themes regarding participants' experiences, breastfeeding decisions, and behaviors. To examine whether sleep disturbance during pregnancy predicted breastfeeding (BF) rates, we defined "lower sleep efficiency" (LSE) and "higher sleep efficiency" (HSE) groups based on the median split of actigraphic SE at 33 weeks' gestation (cutoff SE = 84.9%) and classified mothers as No-BF, Mixed-BF (BF + formula), and Exclusive-BF at 2 weeks postpartum.

RESULTS

Percentages of women who did any breastfeeding were: Week 2 = 72.3%, Week 6 = 62.5%, Week 16 = 50%. LSE mothers were less likely than HSE mothers to initiate breastfeeding (percent No-BF: LSE = 45.8%, HSE = 16.7%, P < .05). Average actigraphic sleep onset, sleep offset, time in bed, sleep duration, and SE did not differ based on breastfeeding status at any time point. Qualitative themes included insufficient preparation for the demands of breastfeeding, interrupted and nonrestorative sleep, and unrelenting daytime tiredness.

CONCLUSIONS

In our sample, preserved actigraphic SE during pregnancy was associated with initiation and continuation of breastfeeding. Future work should examine whether improving sleep in pregnancy improves mothers' feeding experiences.

Determinants of exclusive breastfeeding for the first six months in China: a cross-sectional study

Background

Breast milk is the best source of essential nutrients and bioactive components for infants under 6 months. However, little is known about what affects breastfeeding intentions and practices of Chinese mothers. With measures of individual, setting, and sociocultural factors, this study examined determinants of exclusive breastfeeding in the first 6 months of infancy in China.

Methods

Data were obtained from a national cross-sectional survey in China in 2018 that included 5237 infants under 6 months with available measurements of breastfeeding. A 24-h reported food recall method was applied to assess breastfeeding and complementary food intake in the past 24 h. Potential breastfeeding determinants categorized into six aspects were measured: (1) infant health, (2) maternal sociodemographic characteristics, (3) maternal health, (4) breastfeeding support from family, friends, and workplace, (5) social support for breastfeeding, and (6) maternal breastfeeding experiences and knowledge. Reasons for non-commencement or early cessation of breastfeeding were evaluated for non-breastfed infants. For breastfed infants, multivariate logistic regression was used to explore the determinants of exclusive breastfeeding.

Results

About 30 % (29.5%) of infants under 6 months were exclusively breastfed; 2.3% (2.3%) had never been breastfed and 3.2% had ceased breastfeeding. No breast milk (60.7%), maternal illness (13.9%), and infant illness (13.1%) were the top three reasons for non-commencement of breastfeeding. Insufficient breast milk was the reason given for ceasing breastfeeding early by almost two thirds of caregivers who had stopped breastfeeding. The following factors were associated with exclusive breastfeeding: maternal higher education, formal employment with ≥6 months of paid maternity leave, support of the husband and best friends for breastfeeding, a breastfeeding-supportive society, and better breastfeeding knowledge and experiences (a previous successful breastfeeding experience ≥6 months and early initiation of breastfeeding). Maternal age of ≥40 years, caesarean delivery, and infant disease history were associated with non-exclusive breastfeeding.

Conclusions

The exclusive breastfeeding rate is still very low in China. Multidimensional barriers contribute to this situation. A comprehensive intervention framework is needed to increase optimal breastfeeding and achieve substantial public health gains.

Moving Beyond Breastfeeding Initiation: A Qualitative Study Unpacking Factors That Influence Infant Feeding at Hospital Discharge Among Urban, Socioeconomically Disadvantaged Women

BACKGROUND

Factors that influence breastfeeding initiation and duration have been well established; however, there is limited understanding of in-hospital exclusive breastfeeding (EBF), which is critical for establishing breastfeeding. Grady Memorial Hospital, which serves a high proportion of participants receiving Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and racial/ethnic minorities, had an in-hospital EBF rate in 2018 by the Joint Commission's definition of 29% and sought contextualized evidence on how to best support breastfeeding mothers.

OBJECTIVE

The objectives were to (1) identify facilitators and barriers to in-hospital EBF and (2) explore breastfeeding support available from key stakeholders across the social-ecological model.

DESIGN

In-depth, semistructured interviews were conducted and analyzed using thematic analysis.

PARTICIPANTS

The sample included a total of 38 purposively sampled participants from Grady Memorial Hospital (10 EBF mothers, 10 non-EBF, and 18 key stakeholders such as clinicians, community organizations' staff, and administrators).

RESULTS

Key themes included that maternal perception of inadequate milk supply was a barrier to in-hospital EBF at the intrapersonal level. At the interpersonal level, a personable and individualized approach to breastfeeding counseling may be most effective in supporting EBF. At the institutional level, key determinants of EBF were gaps in prenatal breastfeeding education, limited time to provide comprehensive prenatal education to high-risk patients, and practical help with latching and positioning. Community-level WIC services were perceived as a facilitator due to the additional benefits provided for EBF mothers; however, the distribution of WIC vouchers for formula to mothers while they are in the hospital undermines the promotion of EBF. Cultural norms and a diverse patient population were reported as barriers to providing support at the macrosystem level.

CONCLUSION

Multipronged approaches that span the social-ecological model may be required to support early EBF in hospital settings.

Mixed milk feeding: a systematic review and meta-analysis of its prevalence and drivers

CONTEXT

Extensive literature is available on exclusive breastfeeding and formula-feeding practices and health effects. In contrast, limited and unstructured literature exists on mixed milk feeding (MMF), here defined as the combination of breastfeeding and formula feeding during the same period in term infants > 72 hours old (inclusion criterion).

OBJECTIVE

A systematic review and meta-analysis were performed, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, on the global prevalence of MMF (primary outcome) and related drivers and practices (secondary outcomes).

DATA SOURCES

The search of MMF in generally healthy populations was conducted across 6 databases, restricted to publications from January 2000 to August 2018 in English, Spanish, French, and Mandarin.

DATA EXTRACTION

Two reviewers independently performed screenings and data extraction according to a priori inclusion and exclusion criteria.

DATA ANALYSIS

Of the 2931 abstracts identified, 151 full-text publications were included for data extraction and 96 of those were included for data synthesis (the majority of those were cross-sectional and cohort studies). The authors summarized data across 5 different categories (feeding intention prenatally, and 4 age intervals between > 72 hours and > 6-23 months) and 5 regional subgroups. The overall prevalence of MMF across different age intervals and regions varied between 23% and 32%; the highest rate was found for the age group 4-6 months (32%; 95% confidence interval, 27%-38%); regional comparisons indicated highest MMF rates in Asia (34%), North and South America (33%), and Middle East and Africa together (36%), using a random effects meta-analysis model for proportions. Some drivers and practices for MMF were identified.

CONCLUSION

MMF is a widespread feeding reality. A shared and aligned definition of MMF will help shed light on this feeding practice and evaluate its influence on the duration of total breastfeeding, as well as on infants' nutrition status, growth, development, and health status in the short and long terms.

Factors associated with abandoning exclusive breastfeeding in Mexican mothers at two private hospitals

BACKGROUND

Exclusive breastfeeding (EBF) has multiple benefits for both the child and the mother; however, there is little data regarding the reason why Mexican mothers with a high socio-economic level abandon EBF before 6 months, and there is limited information about the practice of breastfeeding in private hospitals. The objective was to identify the factors associated with the cessation of exclusive breastfeeding in Mexican mothers at two private hospitals.

METHODS

A cross-sectional study was conducted with 218 upper-class mothers selected according to their place of residence by geographic location, socio-economic level, and pediatric consultations cost. They were over 18 years old and with children aged 6 to 24 months. Data were collected between July and November 2016 by face to face interview using a structured questionnaire while the mothers waited for the pediatric postnatal care consultation in two private hospitals in northeastern Mexico. Exclusive breastfeeding was measured according to World Health Organization (WHO) recommendations, which consist of providing only breast milk for the first 6 months of life. Chi-squared tests and multivariate logistic regression were performed.

RESULTS

Mean maternal age was 31.4 years (SD of 4.4) and most of the participants had an undergraduate education, were married, and worked outside the home. The prevalence of exclusive breastfeeding at 6 months was 28%. Upper-class working mothers are less likely to continue breastfeeding. There was a negative association with employment (AOR 13.69; 95% CI 1.59, 111.11), bottle use in the first 6 months (AOR 7.93; 95% CI 3.07, 20.48), and a low level of knowledge (AOR 2.18; 95% CI 1.04, 4.56). After 6 months, only 61 mothers (28%) maintained exclusive breastfeeding.

CONCLUSIONS

Knowledge level, bottle use, and employment are associated with premature cessation of EBF in Mexican upper-class mothers, attending two private hospitals. There was a high percentage of breastfeeding cessation in the sample. It is necessary to reinforce a strategy that coordinates the action of the different laws, regulations and programs affecting the exclusive breastfeeding practice, in order to adequately promote breastfeeding and support mothers in both public and private sectors.

Differences in breastfeeding rate between mothers delivering by caesarean section and those delivering vaginally

Aim: The aim of the study was to analyse the impact of delivery on breastfeeding at 6 months, with special focus on caesarean section combined with established breastfeeding at 2 months. Methods: Delivery mode and breastfeeding at 2 and 6 months were studied in a database of 130,993 infants from two Swedish counties between 1990-2011. Results: The difference in breastfeeding rates at 6 months between children delivered by caesarean section and children delivered vaginally was smaller in a subpopulation of children with established breastfeeding at 2 months compared to all children. The impact of delivery method on breastfeeding at 6 months was independent of child gender, mother's first child, maternal smoking and maternal education. Conclusions: Breastfeeding in mothers giving birth by caesarean section is more likely to continue until (at least) 6 months if established early (at 2 months). It may be worthwhile to promote breastfeeding for mothers who deliver by caesarean section.

Early Term Delivery and Breastfeeding Outcomes

OBJECTIVE

Higher rates of adverse outcomes have been reported for early term (37 0 to 38 6 weeks) versus full term (≥ 39 0 weeks) infants, but differences in breastfeeding outcomes have not been systematically evaluated. This study examined breastfeeding initiation and exclusivity in early and full term infants in a large US based sample.

METHODS

This secondary analysis included 743 geographically- and racially-diverse women from the Measurement of Maternal Stress Study cohort, and 295 women from a quality assessment at a hospital-based clinic in Evanston, IL. Only subjects delivering ≥ 37 weeks were included. Initiation of breastfeeding (IBF) and exclusive breastfeeding (EBF) were assessed via electronic medical record review after discharge. Associations of IBF and EBF with early and full term delivery were assessed via univariate and multivariate logistic regression.

RESULTS

Among 872 women eligible for inclusion, 85.7% IBF and 44.0% EBF. Early term delivery was not associated with any difference in frequency of IBF (p = 0.43), but was associated with significantly lower odds of EBF (unadjusted OR 0.61, 95% CI 0.466, 0.803, p < 0.001). This association remained significant (adjusted OR 0.694, 95% CI 0.515, 0.935, p = 0.016) after adjusting for maternal diabetes, hypertensive disorders of pregnancy, cesarean delivery, maternal age, race/ethnicity, parity, Medicaid status, NICU admission, current smoking, and delivery hospital.

CONCLUSIONS FOR PRACTICE

Despite comparable breastfeeding initiation frequencies, early term infants were significantly less likely to be exclusively breastfed compared to full term infants. These data suggest that women with early term infants may benefit from counseling regarding the potential for breastfeeding difficulties as well as additional breastfeeding support after delivery.

International Board Certified Lactation Consultants' Practices Regarding Supplemental Feeding Methods for Breastfed Infants

BACKGROUND

According to the Baby Friendly Hospital Initiative, when supplementary feeding occurs, mothers should be counseled on the use and risks of feeding bottles and teats. To help support this initiative it is important to understand the supplementation practices of Internationally Board Certified Lactation Consultants (IBCLC)®.

RESEARCH AIMS

To determine (1) if the location of an IBCLC's practice has any impact on supplemental feeding methods; (2) the preferred methods of and the main reasons for supplementation; (3) the level of an IBCLC's confidence with supplemental feeding methods; (4) who is making supplemental feeding decisions; and (5) if there are geographical differences among supplementation choices and reasons for supplementation.

METHODS

An exploratory, descriptive, cross sectional survey of IBCLCs was conducted to generate data about their use of supplemental feeding methods. The survey was sent via email invitation through the International Board of Lactation Consultant's Board of Examiners, with a response rate of 11.5% (N = 2,308).

RESULTS

There was no standard method of supplementation among participants. Participants indicated that they were confident advising mothers on alternative feeding methods. Only 17.6% (n = 406) of participants reported that the IBCLC was the caregiver who recommended the method of supplementation used. The majority of participants believed the Supplemental Feeding Tube Device SFTD) best preserves the breastfeeding relationship, and this was their preferred method of supplementation. However, the bottle was ranked as the number one method used in the United States, Australia, and Canada. The use of alternative feeding methods may be overwhelming to the mother.

CONCLUSION

Supplementation by alternative feeding methods might help preserve the breastfeeding relationship and help reach the World Health Organization's goal of increasing exclusive breastfeeding rates.

Formula Feeding and Associated Factors among a Group of Egyptian Mothers

BACKGROUND

Breastfeeding provides an unequalled way of infant nutrition, despite that, the rate of exclusive breastfeeding for the first 6 months in Egypt is only 13%, and the rates of artificial feeding are rising.

AIM

The current study aimed to explore the reasons for the use of artificial feeding among mothers receiving subsidised milk from formula dispensing centres in Egypt, and to detect the reasons behind the use of a formula only for infant feeding rather than mixed breastfeeding and artificial feeding.

METHODS

This exploratory cross-sectional study involved 197 mothers; who attended centres for dispensing subsidised artificial formula at primary health care facilities (PHC) in El-Fayom and Ismailia governorates via a purposive sampling technique. The study spanned over 6-months duration from June till December 2018.

RESULTS

A statistically significant higher percentage of artificial feeding only was noticed in male infants (47.5% in the AF group only versus 28.7% in the mixed feeding group (p = 0.018), and infants aged 6-12 months (47.5% in the AF group only versus 28.7% in the mixed feeding group, p = 0.032). A statistically significant higher percentage of artificial feeding only was noticed among infants born to mothers who have general anaesthesia during labour (67.2% in the AF group only versus 41.9% in the mixed feeding group, p = 0.004), and among infants born to mothers who think that formula feeding is better (13.1% in the AF group only versus 0.7% in the mixed feeding group, or that formula has a similar quality to breast milk (6.6%% in the AF group only versus 4.4% in the mixed feeding group, p = 0.0004. The most common reasons for formula feeding reported by both groups were perceived breast milk insufficiency (60.9%), weak babies (50.3%), and doctors' advice (37%). Previous negative breastfeeding experience and the need for own body privacy were the two reasons which differed statistically in both groups p = 0.004 and 0.008, respectively.

CONCLUSION

Antenatal care education is essential to improve mothers' knowledge and practice of breastfeeding. Baby-friendly hospital initiative implementation is essential to ensure early initiation and continuation of breastfeeding.

Early Feeding Behaviors and Breastfeeding Outcomes After Cesarean Section

Objective: To explore the relationship of early breastfeeding behaviors after Cesarean section (CS) to long-term breastfeeding outcome. Materials and Methods: A total of 648 healthy breastfeeding primiparas (333 delivered by CS, and 315 by vaginal birth) were recruited from three teaching hospitals using probability proportional to size sampling method. Data of the first 3 days breastfeeding behaviors, including breastfeeding initiation, frequency and duration, formula supplement, and infant sucking performance, were gathered. Ordinal cumulative odds logistic regression model were conducted to explore the effect of CS on breastfeeding outcome at fifth day, and first, fourth, and sixth month before and after adjusting for the variants of early breastfeeding behaviors. Results: The unadjusted odds ratios (ORs) for lower breastfeeding rates associated with CS were 2.11 (95% confidence interval [CI]: 1.58-2.81), 2.67 (95% CI: 1.96-3.63), 1.60 (95% CI: 1.19-2.15), and 1.36 (95% CI: 1.01-1.83) at the fifth day, and first, fourth, and sixth month. After adjusting for the early breastfeeding behaviors, the negative effect of CS on long-term breastfeeding was attenuated, and no longer significant at fifth day (OR: 1.01, 95% CI: 0.70-1.47) and fourth month (OR: 1.13, 95% CI: 0.79-1.62) and sixth month (OR: 0.81, 95% CI: 0.56-1.17). Conclusions: CS had a detrimental effect on early breastfeeding behaviors and long-term breastfeeding outcomes. CS per se is not a negative factor, but rather those infants who have feeding difficulties in the immediate postpartum period have long-term problems.

In-hospital formula supplementation and breastfeeding initiation in infants born to women with pregestational diabetes mellitus

OBJECTIVE

To ascertain the rate of in-hospital supplementation as it relates to early breastfeeding (BF) and early formula feeding (FF) and its effects on BF (exclusive and partial) at the time of discharge for infants born to women with pregestational diabetes mellitus (PGDM).

METHODS

Retrospective cohort investigation of 282 women with PGDM who intended to BF and their asymptomatic infants admitted to the newborn nursery for blood glucose monitoring and routine care. Early feeding was defined by the initial feeding if given within four hours of birth.

RESULTS

Of the 282 mother-infant dyads, for 134 (48%) early feeding was BF and for 148 (52%) early feeding was FF. Times from birth to BF and FF (median 1 hr, 0.3-6) were similar, while the time to first BF for those who FF and supplemented was longer (median 6 hr., 1-24). Ninety-seven infants (72%) who first BF also supplemented. Of these, 22 (23%) BF exclusively, 67 (69%) BF partially and 8 (8%) FF at discharge. One hundred seventeen (79%) who first FF also supplemented. Of these, 21 (18%) BF exclusively, 76 (65%) BF partially and 20 (17%) FF at discharge.

CONCLUSION

Regardless of the type of first feeding, the majority of infants born to women with PGDM require supplementation. Even when medically indicated, in-hospital supplementation is an obstacle, albeit not absolute, to exclusive BF at discharge. Parents should be reminded that occasional supplementation should not deter resumption and continuation of BF.

The influence of time of birth and seasonal variations on weight loss in breastfeeding neonates

BACKGROUND

Breastfeeding (BF) neonates generally lose weight after birth. Neonatal factors like gestational age, birth weight and mode of delivery can affect the neonatal weight loss after birth. Similarly, maternal age, parity and illness may contribute to newborn weight loss. However, influence of the time of birth and season on changes in weight is not well elucidated.

OBJECTIVE

The aim of this study is to determine the effect of birth time and the seasonal variations on weight loss in BF newborns.

METHODS

In this retrospective study of a prospectively maintained database of two sets of groups, from January 2013 to October 2016, were evaluated- Birth time group and Seasonal group; Birth time of the groups was: night time 7pm to 7am and day time 7am to 7pm; and the seasonal variations groups studies were summer, fall, winter and spring. Weight loss of >5%, 7%, and 10% at <24 hours (h), 48 h and 72 h of birth, respectively, were considered as a significant weight loss. Preterm, exclusively formula fed and neonates admitted to NICU were excluded.

RESULTS

A total of 2044 newborns were analyzed. In the birth time group, babies born during the night time had significantly lost >5% of birth weight at <24 h (p < 0.01) and >7% birth weight at <48 h of life (p < 0.02). Weight loss >10% at <72 h was similar in both birth time cohorts. C-section, prolonged rupture of membrane, and maternal pre-delivery hospital stay for >12 h were significant contributing factors. Whereas, seasonal variations were not associated with weight loss in neonates.

CONCLUSION

BF babies born at night time lose significantly more weight during the first two days of life and seasonal association was not found to affect weight loss in the neonates.

Factors Influencing Southeastern U.S. Mothers' Participation in Baby-Friendly Practices: A Mixed-Methods Study

BACKGROUND

Mothers in the southeastern United States, including rural-dwelling and African American mothers, have historically had low rates of breastfeeding; however, no studies have investigated these mothers' experiences of breastfeeding support processes associated with the Baby-Friendly Hospital Initiative. Research aim: This study aimed to determine factors influencing southeastern U.S. mothers' participation in Baby-Friendly practices and breastfeeding decisions.

METHODS

Using a convergent parallel mixed-methods design, medical record review of mother-infant dyads ( n = 234) provided data to determine if those who participated in more than half of the Ten Steps to Successful Breastfeeding had improved breastfeeding outcomes. Logistic regression was conducted to determine whether maternal demographic/clinical characteristics were predictive of Baby-Friendly practice participation. Qualitative methods included in-depth interviews ( n = 16). Directed content analysis was conducted to identify themes. Results of the analysis of the two data sets were triangulated to enhance understanding of mothers' barriers to and facilitators of participation in Baby-Friendly practices.

RESULTS

Rural-dwelling and African American mothers had greater odds of nonparticipation in Baby-Friendly practices relative to other groups (odds ratios = 5 and 10, respectively; p ≤ .01). Mothers who received lactation consultation and had moderate (15-44 min) or completed (≥ 45 min) skin-to-skin contact had greater odds of participation in Baby-Friendly practices (both odds ratios ≥ 17.5; p < .05). Directed content analysis revealed six themes: maternal desire to breastfeed, infant state, maternal state, milk supply concerns, provider support, and access to breastfeeding equipment and support services.

CONCLUSION

Rural-dwelling African American mothers had limited knowledge of Baby-Friendly practices; however, culturally tailored services could improve Baby-Friendly practice participation and breastfeeding success.

Influences of Cesarean Delivery on Breastfeeding Practices and Duration: A Prospective Cohort Study

BACKGROUND

Mothers are encouraged to exclusively breastfeed for the first 6 months. However, cesarean delivery rates have increased worldwide, which may affect breastfeeding. Research aim: This study aimed to determine the potential effects of cesarean delivery on breastfeeding practices and breastfeeding duration.

METHODS

This was a 6-month cohort study extracted from a 24-month prospective cohort study of mother-infant pairs in three communities in Hunan, China. Data about participants' characteristics, delivery methods, breastfeeding initiation, use of formula in the hospital, exclusive breastfeeding, and any breastfeeding were collected at 1, 3, and 6 months following each infant's birth. The chi-square test, logistic regression model, and Cox proportional hazard regression model were used to examine the relationship between breastfeeding practices and cesarean delivery.

RESULTS

The number of women who had a cesarean delivery was 387 (40.6%), and 567 (59.4%) women had a vaginal delivery. The exclusive breastfeeding rates at 1, 3, and 6 months were 80.2%, 67.4%, and 21.5%, respectively. Women who had a cesarean delivery showed a lower rate of exclusive breastfeeding and any breastfeeding than those who had a vaginal delivery ( p < .05). In addition, cesarean delivery was related with using formula in the hospital and delayed breastfeeding initiation. Cesarean delivery also shortened the breastfeeding duration (hazard ratio = 1.40, 95% confidence interval [1.06, 1.84]).

CONCLUSION

Healthcare professionals should provide more breastfeeding skills to women who have a cesarean delivery and warn mothers about the dangers of elective cesarean section for breastfeeding practices.

Formula Milk Supplementation on the Postnatal Ward: A Cross-Sectional Analytical Study

Breastfeeding rates are low in the UK, where approximately one quarter of infants receive a breastmilk substitute (BMS) in the first week of life. We investigated the reasons for early BMS use in two large maternity units in the UK, in order to understand the reasons for the high rate of early BMS use in this setting. Data were collected through infant feeding records, as well as maternal and midwife surveys in 2016. During 2016, 28% of infants received a BMS supplement prior to discharge from the hospital maternity units with only 10% supplementation being clinically indicated. There was wide variation in BMS initiation rates between different midwives, which was associated with ward environment and midwife educational level. Specific management factors associated with non-clinically indicated initiation of BMS were the absence of skin-to-skin contact within an hour of delivery (p = 0.01), and no attendance at an antenatal breastfeeding discussion (p = 0.01). These findings suggest that risk of initiating a BMS during postnatal hospital stay is largely modifiable. Concordance with UNICEF Baby Friendly 10 steps, attention to specific features of the postnatal ward working environment, and the targeting of midwives and mothers with poor educational status may all lead to improved exclusive breastfeeding rates at hospital discharge.

Personalized weight change prediction in the first week of life

BACKGROUND & AIMS

Almost all neonates show physiological weight loss and consecutive weight gain after birth. The resulting weight change profiles are highly variable as they depend on multiple neonatal and maternal factors. This limits the value of weight nomograms for the early identification of neonates at risk for excessive weight loss and related morbidities. The objective of this study was to characterize weight changes and the effect of supplemental feeding in late preterm and term neonates during the first week of life, to identify and quantify neonatal and maternal influencing factors, and to provide an educational online prediction tool.

METHODS

Longitudinal weight data from 3638 healthy term and late preterm neonates were prospectively recorded up to 7 days of life. Two-thirds (n = 2425) were randomized to develop a semi-mechanistic model characterizing weight change as a balance between time-dependent rates of weight gain and weight loss. The dose-dependent effect of supplemental feeding on weight gain was characterized. A population analysis applying nonlinear mixed-effects modeling was performed using NONMEM 7.3. The model was evaluated on the remaining third of neonates (n = 1213).

RESULTS

Key population characteristics (median [range]) of the whole sample were gestational age 39.9 [34.4-42.4] weeks, birth weight 3400 [1980-5580] g, maternal age 32 [15-51] years, cesarean section 26%, and girls 50%. The model demonstrated good predictive performance (bias 0.01%, precision 0.56%), and is able to accurately predict individual weight change (bias 0.15%, precision 1.43%) and the dose-dependent effects of supplemental feeding up to 1 week after birth based on weight measurements during the first 3 days of life, including birth weight, and the following characteristics: gestational age, gender, delivery mode, type of feeding, maternal age, and parity.

CONCLUSIONS

We present the first mathematical model not only to describe weight change in term and late preterm neonates but also to provide an educational online tool for personalized weight prediction in the first week of life.

Postpartum Mothers' Experiences With Newborn Weight Checks in the Home

Few researchers have examined the perspectives of breastfeeding mothers about using a pediatric scale in the home to monitor infant weight. A cross sectional design was used to measure helpfulness, impact on newborn feeding, and confidence among mothers who used a digital scale to monitor newborn weight. Women (N = 69) who had given birth in a community hospital in the Northeast region of the United States used a pediatric scale in the home daily for 2 weeks after birth. An online survey determined helpfulness of the scale, if use of the scale impacted feedings, and confidence in breastfeeding. Using a pediatric scale to monitor newborn weight was very helpful (n = 49; 71%); it was most helpful for primiparous women (P < .016). Feeding frequency often changed on the basis of neonatal weight (n = 27; 39%) but only 9% (n = 6) changed the type of milk fed. Confidence in breastfeeding increased in 90% (n = 62) of participants. A pediatric scale used in the home to monitor newborn weight is helpful for breastfeeding, especially for primiparous women. Use of the scale may increase maternal confidence in breastfeeding and help guide decisions about feeding frequency.

Donor Milk Utilization for Healthy Infants: Experience at a Single Academic Center

BACKGROUND

Banked donor milk (BDM) has historically been used as an alternative to formula for preterm infants. Recently, BDM has been endorsed by two national organizations for use in healthy infants. We sought to quantify utilization trends and characteristics of mothers and their healthy newborns who received BDM during their postpartum stay between 2013 and 2016 at a single academic medical center.

MATERIALS AND METHODS

In this observational study, we used a clinical log to identify all infants who received BDM in the well-baby nursery between July 2013 and June 2016. From this log, we abstracted data on the numbers of babies who received BDM, the quantity of BDM provided, and indications for usage. We also collected clinical data from the medical records of a subset of corresponding mothers and infants.

RESULTS

BDM utilization increased over time in healthy infants, with 0.04% of infants before July 2014 receiving BDM compared with 4.7% in July 2015 to June 2016. During the same periods, the number of bottles provided per infant also increased, from 0.6 bottles per infant to 4.6 bottles per infant. The most common indications for providing BDM were parent/caregiver request (19%) and excessive weight loss/dehydration (17%).

CONCLUSION

At our center, the use of BDM for healthy infants increased substantially over the study period. More research is urgently needed to understand the repercussions of this practice on resource utilization as well as short- and long-term breastfeeding and health outcomes.

Determinants of Nonmedically Indicated In-Hospital Supplementation of Infants Whose Birthing Parents Intended to Exclusively Breastfeed

BACKGROUND

Despite high rates of intention to exclusively breastfeed, rates of exclusive breastfeeding in Canada are low. Supplementation may begin in hospital and is associated with reduced breastfeeding duration. Research aim: The aim of this investigation was to explore determinants of in-hospital nonmedically indicated supplementation of infants whose birthing parents intended to exclusively breastfeed.

METHODS

This study is a cross-sectional one-group nonexperimental design, focused on participants who intended to exclusively breastfeed for 6 months ( n = 496). Data were collected between October 2011 and October 2015 in Newfoundland and Labrador. Variables measured included age; rural/urban location; education; income; race; marital status; parity; smoking status; having been breastfed as an infant; previous breastfeeding experience; Iowa Infant Feeding Attitude Scale score; delivery mode; infant birth weight; birth satisfaction; skin-to-skin contact; length of participant's hospital stay; breastfeeding advice from a lactation consultant, registered nurse, or physician; and first impression of breastfeeding. We evaluated determinants of in-hospital nonmedically indicated supplementation using bivariate and multivariate logistic regression analyses.

RESULTS

Overall, 16.9% ( n = 84) of infants received nonmedically indicated supplementation in hospital. Multivariate modeling revealed four determinants: low total prenatal Iowa Infant Feeding Attitude Scale score (odds ratio [OR] = 1.96, 95% confidence interval [CI] [1.18, 3.27]), no previous breastfeeding experience (OR = 2.03, 95% CI [1.15, 3.61]), negative first impression of breastfeeding (OR = 2.67, 95% CI [1.61, 4.43]), and receiving breastfeeding advice from a hospital physician (OR = 2.86, 95% CI [1.59, 5.15]).

CONCLUSION

Elements of the hospital experience, self-efficacy, and attitudes toward infant feeding are determinants of nonmedically indicated supplementation of infants whose birthing parents intended to exclusively breastfeed.

Maternal experiences with and sources of information on galactagogues to support lactation: a cross-sectional study

An increase in the marketing and use of herbal galactagogues among breastfeeding mothers in the US has raised the issue of how best to provide support and information on the use of these products, particularly in light of limited availability of certified lactation counselors and continued suboptimal rates of breastfeeding globally. Currently, no cross-sectional data are available on the experiences and attitudes of mothers regarding the use of herbal and pharmaceutical galactagogues for lactation in the US. The findings of an online survey of 188 breastfeeding mothers on experiences with and sources of information on galactagogues are presented. Most mothers (76%) reported that while breastfeeding, they felt as though they were not making enough milk to meet the needs of their child, and yet 54% also indicated that they had not supplemented with formula. A large proportion of respondents reported utilizing galactagogues to increase lactation and finding them useful. The results indicated that most women learned about galactagogues from the Internet or by word of mouth through friends. Lactation consultants were the third-most reported sources of information on these products. While many respondents reported perceiving galactagogues as innocuous, more evidence on safety and efficacy is needed to support women properly who seek out and use them. Large-scale studies of the prevalence of galactagogue use in the US and rigorous evaluation of use globally are needed to ensure that mothers who choose to breastfeed may safely avail themselves of all options when counseling support is insufficient.

Baby-led compared with scheduled (or mixed) breastfeeding for successful breastfeeding

BACKGROUND

Baby-led breastfeeding is recommended as best practice in determining the frequency and duration of a breastfeed. An alternative approach is described as scheduled, where breastfeeding is timed and restricted in frequency and duration. It is necessary to review the evidence that supports current recommendations, so that women are provided with high-quality evidence to inform their feeding decisions.

OBJECTIVES

To evaluate the effects of baby-led compared with scheduled (or mixed) breastfeeding for successful breastfeeding, for healthy newborns.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (23 February 2016), CINAHL (1981 to 23 February 2016), EThOS, Index to Theses and ProQuest database and World Health Organization's 1998 evidence to support the 'Ten Steps' to successful breastfeeding (10 May 2016).

SELECTION CRITERIA

We planned to include randomised and quasi-randomised trials with randomisation at both the individual and cluster level. Studies presented in abstract form would have been eligible for inclusion if sufficient data were available. Studies using a cross-over design would not have been eligible for inclusion.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed for inclusion all potential studies we identified as a result of the search strategy. We would have resolved any disagreement through discussion or, if required, consulted a third review author, but this was not necessary.

MAIN RESULTS

No studies were identified that were eligible for inclusion in this review.

AUTHORS' CONCLUSIONS

This review demonstrates that there is no evidence from randomised controlled trials evaluating the effect of baby-led compared with scheduled (or mixed) breastfeeding for successful breastfeeding, for healthy newborns. It is recommended that no changes are made to current practice guidelines without undertaking robust research, to include many patterns of breastfeeding and not limited to baby-led and scheduled breastfeeding. Future exploratory research is needed on baby-led breastfeeding that takes the mother's perspective into consideration.
