Factors Affecting Breastfeeding Outcomes at Six Months in Preterm Infants

A parent-administered sensorimotor intervention for oral feeding in infants born preterm: A randomized clinical study

AIM

To evaluate the effect of a parent-administered sensorimotor intervention (PASI) program on developmental outcomes of infants born preterm during their stay in the neonatal intensive care unit (NICU).

METHOD

A randomized clinical study was conducted with 94 infants (mean gestational age 31 weeks [SD 2.2 weeks]; 1658 g [SD 478 g]; 49 males, 45 females) initially enrolled and randomly assigned to an experimental or a control group. Infants in the experimental group received a PASI, consisting of tactile input to oral structures, trunk/limbs, and non-nutritive sucking for 15 minutes, once a day, for 10 days. Infants in the control group received standard care. Outcomes included attainment of complete oral feeds, occurrence of direct breastfeeding at hospital discharge, and motor function assessed using the Test of Infant Motor Performance (TIMP).

RESULTS

A total of 80 infants completed the study. Infants in the experimental group achieved complete oral feeds sooner (11.9 [SD 4.3] vs 15.3 [SD 6.5] days, p = 0.013), and a greater number of them received direct breastfeeds (22 vs 12, p = 0.010) than controls. Infants in both groups had equivalent motor functions scores on the TIMP (46.9 [SD 4.8], 46.8 [SD 8.4], p = 0.961).

INTERPRETATION

A PASI program may enhance an infant's oral feeding skills. These findings provide evidence to advocate for the institution of PASI in NICUs.

Human milk feeding for moderate and late preterm infants at age 2 months: Insights from a cluster randomized controlled trial 2-month follow-up

Objective

Human milk (HM) is the optimal nutrition for infants; preterm infants demonstrate shorter HM feeding duration. Care interventions may increase HM feeding among preterm infants after NICU discharge. We compared Alberta Family Integrated Care (FICare) versus Standard Care on HM feeding in preterm infants at age 2 months.

Methods

We conducted a follow-up of a cluster randomized controlled trial of 455 infants and their mothers with data linked to the infant's 2-month public health visit. We used partial proportional odds to model group differences and factors associated with feeding type: exclusive HM (EHM), Non-EHM, or no HM (NHM).

Results

Compared to Standard Care, mothers in Alberta FICare were less likely to provide EHM versus NHM. There was no group difference between EHM and Non-EHM. Mothers with higher education who were on maternity leave or employed were more likely to provide EHM. Infants who received EHM at discharge were more likely to continue at age 2 months. Higher maternal breastfeeding self-efficacy at discharge was associated with a greater likelihood of EHM.

Conclusion

Alberta FICare was not associated with EHM feeding at age 2 months.

Innovation

Different factors predicted the three HM feeding categories, suggesting the need to individualize feeding supports.Trial Registration.ClinicalTrials.gov Identifier NCT02879799, retrospectively registered August 26, 2016.

Impact of theory of planned behavior based intervention on breastfeeding patterns of the mothers with preterm infants: a randomized trial

BACKGROUND

The birth of a preterm infant is considered a crisis for the mother and the family. Given the significance of breastfeeding for these high-risk infants, failure to initiate and maintain exclusive breastfeeding in this group of infants is a prevalent and serious problem. The aim of this research was to investigate the impact of Theory of Planned Behavior based intervention on breastfeeding patterns of the mothers with preterm infants: a randomized trial.

MATERIALS AND METHODS

This study is a field trial conducted in Isfahan, Iran in 2021-2022. It included 72 mothers of late preterm infants, divided into the intervention (n = 36) and control (n = 36) groups. The intervention group received four training sessions focused on breastfeeding patterns based on the Theory of Planned Behavior. Before, immediately after, and two and four months after the intervention, the constructs of the Theory of Planned Behavior related to breastfeeding patterns were assessed using a researcher-made questionnaire, and the infant's breastfeeding pattern was recorded. Statistical analysis was performed using SPSS version 19, g repeated measures ANCOVA, Bonferroni post hoc test, and chi-square test.

RESULTS

The results indicated that immediately after the intervention, as well as two and four months later, the mean scores for attitude (P < 0.001), subjective norms (P < 0.001), perceived behavioral control (P < 0.001), and behavioral intention (P < 0.001) were significantly higher in the intervention group than in the control group. Additionally, the results showed that, the rate of breastfeeding immediately, two months, and four months after the intervention was significantly higher in the intervention group than before the intervention (P < 0.001). However, in the control group, the rate of breastfeeding immediately, two months, and four months after the intervention was significantly lower than before the intervention (P < 0.001).

CONCLUSION

Interventions based on the Theory of Planned Behavior can improve exclusive breastfeeding in late preterm infants by changing the attitudes, subjective norms, perceived behavioral control and the behavioral intentions of the mothers of preterm infants.

Content validation of the nursing diagnosis "Insufficient breast milk production (00216)"

PURPOSE

To review and validate the elements of the nursing diagnosis (ND) "Insufficient breast milk production" (00216) based on the literature and expert consensus, and to construct operational definitions (ODs) for its defining characteristics (DCs).

METHODS

It is a methodological study carried out in two phases. In the first phase, a scoping review was conducted, and in the second, a committee of experts reviewed the elements' content. Items with a Content Validity Index ≥0.8 were validated for relevance, clarity, and precision. Discussions were conducted until a consensus was reached on all items and criteria evaluated. The Ethics Committee approved the study.

FINDINGS

The final scoping review sample consisted of 61 articles, and 19 experts evaluated the content of the ND. All DCs were revised. Three at-risk populations, three associated conditions, and one related factor were added. Three elements had their category changed, and an element was deleted. Experts also validated ODs developed for all DCs.

CONCLUSION

"Insufficient breast milk production (00216)" was validated by experts. This study improved the ND through literature and expert consensus. New elements were added, and existing ones were revised.

IMPLICATIONS FOR NURSING PRACTICE

This study improves this ND based on scientific evidence and clinical expertise and potentially improves nurses' diagnostic accuracy through ODs.

A swallowing and breastfeeding intervention programme for small and sick neonates embedded in kangaroo mother care

Available evidence of oral sensorimotor interventions for small neonates is not strong. Evidence of interventions for sick term neonates is largely lacking. Studies are limited by risk of bias and inconsistency. Evidence of interventions relying on a single stimulation technique only appears to be low to very low. Ongoing research is required.Contribution: We describe a five-component neonatal swallowing and breastfeeding intervention programme embedded in the practice of kangaroo mother care (KMC). Drawing on oropharyngeal physiology, neonatology, neurodevelopmental care, breastfeeding- and KMC science, the programme is the product of collaboration between a speech-language therapist and a medical doctor, and their team. Its implementation is dependent on coaching mothers and the neonatal care team. Researchers are invited to determine outcomes of the programme.

Breastfeeding Barriers for Preterm Infants in Neonatal Intensive Care Unit Environments: A Systematic Assessment and Meta-Analysis

Background: Breast milk is vital for the growth and development of preterm infants. However, in Neonatal Intensive Care Units (NICUs), mothers often encounter significant challenges in breastfeeding. Objective: This study aims to systematically evaluate the barriers to breastfeeding in NICUs, thereby providing evidence-based support for clinical practices. Methods: A comprehensive search was conducted in the Cochrane Library, PubMed, Web of Science, Embase, and Scopus databases, up to September 2023. Meta-analysis was performed using Stata 15.0, applying fixed or random effects models to calculate odds ratios (OR) and their 95% confidence intervals (CI). Study quality was assessed using the Newcastle-Ottawa Scale for cases and cohorts and the Agency for Healthcare Research and Quality standards for cross-sectional studies. Heterogeneity was evaluated using Cochran's chi-squared test (Cochran's Q) and I2 statistics, and publication bias was assessed through funnel plots and symmetry tests. Results: A total of 32 studies were included, encompassing 96,053 preterm infants. The main barriers to breastfeeding in preterm infants included: low gestational age (OR = 1.36, 95% CI: 1.06-1.75), lower maternal education (OR = 1.64, 95% CI: 1.39-1.93), insufficient breast milk (OR = 2.09, 95% CI: 1.39-1.93), multiple births (OR = 1.615, 95% CI: 1.18-2.210), smoking (OR = 2.906, 95% CI: 2.239-3.771), and single motherhood (OR = 1.439, 95% CI: 1.251-1.654). Conclusion: This study underscores the need for individualized breastfeeding support strategies in NICUs, taking into account the diverse backgrounds of mothers. Future research should focus on unraveling the underlying mechanisms affecting breastfeeding in preterm infants, with the goal of enhancing breastfeeding rates and improving developmental outcomes.

Human Milk-The Biofluid That Nourishes Infants from the First Day of Life

Human milk is a biofluid with a unique composition among mammalian milks. Besides this milk's major components, its bioactive compounds, like hormones, immune factors, and oligosaccharides, are unique and important for infant growth and development. The best form of nutrition for term and preterm infants is the mother's own milk. However, in the absence of the mother's own milk, donor milk should be made available. Milk banks support neonatal intensive care units by providing preterm infants with human milk that generally has reasonable nutritive value for this sensitive population. However, neither mother's own milk nor donor milk has sufficient energy content for the growth of preterm babies, so adequate human milk supplementation is crucial for their progress. Due to the different characteristics of human breast milk, as well as ubiquitous environmental pollutants, such as microplastics, new methods are required for monitoring the quality and characteristics of human milk, which will lay a solid foundation for the further development and progress of human milk research.

Mother's mental health and the interaction with her moderate preterm baby in the NICU

INTRODUCTION

Moderate preterm infants, born between 320/7 and 336/7 weeks, represent a significant number of preterm-born infants; however, they remain a poorly studied group despite their vulnerability. The objective of this correlational study is to describe the impact of having a moderate preterm infant hospitalised in the NICU on the mothers' mental health and how this relates to the interaction between the dyad.

METHOD

During the hospitalisation period, 85 moderate preterm mother-infant dyads participated in this study. The participants provided self-reports of depression, parental stress, and skin to skin and breastfeeding practices. Also, mother-infant interaction was assessed in the NICU with an observational scale.

RESULTS

Mothers evidenced high levels of stress and depressive symptoms during the hospitalization. The stress experienced by these women was significant, although weakly, associated with the interaction with their babies; and mothers of small for gestational age babies showed difficulties in this area.

CONCLUSIONS

The results of this study could represent a contribution to a better understanding of the relation between the characteristics of moderate preterm babies, maternal emotional wellbeing, and the quality of mother-infant interactions in NICU settings.

Human Milk Cessation in the NICU in Infants with Bronchopulmonary Dysplasia

OBJECTIVE

The objective of this study was to identify factors associated with the cessation of human milk prior to neonatal intensive care unit (NICU) discharge for infants diagnosed with bronchopulmonary dysplasia (BPD).

STUDY DESIGN

Participants were recruited from the Johns Hopkins BPD Clinic between January 2016 and October 2018. Clinical and demographic characteristics were analyzed based on whether participants stopped human milk before or after NICU discharge.

RESULTS

Of the 224 infants included, 109 (48.7%) infants stopped human milk prior to discharge. The median duration of human milk intake was less for infants who stopped human milk prior to discharge compared with those who continued after discharge (2 vs. 8 months, p < 0.001). In multivariate regression analysis, pulmonary hypertension (odds ratio [OR]: 2.90; p = 0.016), public insurance (OR: 2.86; p < 0.001), and length of NICU admission (OR: 1.26 per additional month; p = 0.002) were associated with human milk cessation prior to NICU discharge.

CONCLUSION

Infants with BPD who have severe medical comorbidities and markers of lower socioeconomic status may be at higher risk for earlier human milk discontinuation.

KEY POINTS

· Half of infants in our study with BPD who received human milk stopped human milk prior to NICU discharge.. · For infants on human milk after discharge, the duration of human milk intake was 8.6 months.. · Infants with pulmonary hypertension, tracheostomies, and ventilation stopped human milk earlier.. · Non-White race, lower income, and public insurance were predictors of early human milk cessation..

Translation and validation of the Breastfeeding Motivation Scale in China

BACKGROUND

There are several versions of the Breastfeeding Motivation Scale (BMS), which have been shown to measure maternal breastfeeding motivation, but there is not a Chinese version yet. The study aimed to translate the BMS into Chinese and subsequently assess its psychometric properties among Chinese mothers during the postpartum period.

METHODS

The study was composed of two phases. The translation of BMS closely followed the principals of good practices. Phase 1 included a comprehensive translation, back-translation, cross-cultural adaptation, and pretest to develop the Chinese version of the BMS. From 1 December 2021 to 1 July 2022, the Chinese version of the BMS was administered to 206 postnatal mothers in our maternity wards to assess its psychometric properties. Phase 2 involved psychometric property testing, including testing of the internal consistency, test-retest reliability, content validity, construct validity, convergent validity and discriminant validity.

RESULTS

Minor modifications in four items were recommended after translations. The Cronbach's α coefficient of the Chinese version of the BMS was .887, and the intraclass correlation coefficient was .897 (P < 0.001). The model fit was acceptable (χ2/df = 2.40, P < 0.001, RMSEA = 0.08, CFI = 0.91, IFI = 0.92 and TLI = 0.90) according to the confirmatory factor analysis. The composite reliability values corresponding to each latent variable were 0.733 ~ 0.926, and the average variance extracted values were 0.476 ~ 0.653. The correlations among the five measured variables were all lower than .85 and the square roots of average variance extracted from the variable were greater than the interconstruct correlations among the five measured variables in the model.

CONCLUSIONS

The Chinese version of the BMS has good reliability and validity and provides a reliable assessment tool for measuring maternal breastfeeding motivation. It also provides support to develop culturally sensitive interventions for Chinese mothers' who are breastfeeding.

Factors affecting breastfeeding self-efficacy among mothers with preterm infants

BACKGROUND

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

OBJECTIVE

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

DESIGN

A cross-sectional study.

METHODS

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

RESULTS

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

CONCLUSION

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

Cross-cultural adaptation of the Breastfeeding Self-Efficacy Scale Short Form (BSES-SF) modified for preterm mothers in Brazil

OBJECTIVES

to conduct a cross-cultural adaptation of the Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) for mothers of ill and/or preterm infants among Portuguese-speaking mothers in Brazil.

METHODS

a methodological study was completed, including the translation of the tool, synthesis of translations, review by experts, synthesis, reassessment of experts, back-translation, pre-test, and validation of the content. The study involved 19 participants, including a translator and experts. In addition, 18 mothers from the target population were included in the pre-test.

RESULTS

the equivalences of the opinion obtained by the committee of experts were semantic (85%), idiom (89%), cultural (86%), and conceptual (94%). The content validation coefficient (CVC) on the scale was 0.93 for clarity and understanding; 0.89 for practical relevance; 0.92 for relevance; and the average overall CVC was 0.91.

CONCLUSIONS

the scale was translated and adapted to the Brazilian Portuguese language, which maintained the equivalences and confirmed the content validity.

Self-efficacy and breastfeeding outcomes in mothers of premature and term infants: a longitudinal study

PURPOSE

To analyze the breastfeeding self-efficacy in mothers of premature and full-term newborns, in the period of 180 days, and to know the social and obstetric factors that influence the practice of maintaining the exclusive breastfeeding in the period of exclusive recommendation.

METHODS

Cohort with 44 mothers admitted to a public maternity hospital between January and October 2018. The mothers were divided into two groups: Premature and Full-term Groups. The Breastfeeding Self-efficacy Scale was applied in the immediate postpartum period, in addition to a questionnaire elaborated by the authors to collect sociodemographic and obstetric variables. The follow-up was done on the 30th, 120th and 180th days of the newborn's life, by telephone. For the statistical analysis between the groups, the Statistical Package for the Social Sciences (SPSS) was used.

RESULTS

There was no difference in the self-efficacy score, nor in the obstetric and socioeconomic characteristics between the groups, except for family income (lower in the Premature Group - p = 0.031). The diet type was different on the 30th day after delivery (p = 0.023), with greater adherence to the exclusive breastfeeding in the Premature Group. No association was found between breastfeeding self-efficacy and exclusive breastfeeding practice in the 180-day period.

CONCLUSION

In this sample, the breastfeeding self-efficacy was not related to the exclusive breastfeeding practice in the period of 180 days, in both groups. The premature group showed lower family income and greater adherence to exclusive breastfeeding on the 30th day postpartum.

Using the theory of planned behavior model to predict factors influencing breastfeeding behavior among preterm mothers at week 6 postpartum: the mediating effect of breastfeeding intention

Background

Exclusive breastfeeding (EBF) in the first 6 weeks postpartum is key to continued breastfeeding. This study aimed to explore the role of EBF-related predictors (particularly breastfeeding intention) in breastfeeding behavior among preterm mothers at week 6 postpartum based on the theory of planned behavior (TPB).

Methods

A total of 352 mothers of preterm infants were recruited, 340 of whom participated in this study. Prior to discharge, participants completed the Chinese versions of the modified Breastfeeding Attrition Predictive Tool, the Breastfeeding Knowledge Questionnaire (BKQ), the Infant Feeding Intention, and the Edinburgh Postnatal Depression Scale. Responses to the items of the Breastfeeding Behavioral Questionnaire (BBQ) were also collected by telephone at week 6 postpartum. The final analyses included 321 participants who completed the full two-wave data collection.

Results

The fitness indices of the modified TPB model were acceptable. Breastfeeding knowledge and EBF before discharge positively impacted breastfeeding intention, whereas depression had a negative impact. Before discharge, breastfeeding intention fully mediated the impacts of breastfeeding attitude, social and professional support, knowledge, depression, and EBF on breastfeeding behavior and partially mediated the influence of perceived breastfeeding control on breastfeeding behavior.

Conclusion

These findings indicate that TPB accurately predicts breastfeeding behavior among preterm mothers at week 6 postpartum, and breastfeeding intention is key to the above-mentioned EBF-related factors and breastfeeding behavior. The findings underline the need for further longitudinal studies and corresponding interventions for preterm mothers with a high risk of EBF attrition.

The effect of postnatal breastfeeding education given to women on breastfeeding self-efficacy and breastfeeding success

OBJECTIVE

This study was conducted to determine the effect of postnatal breastfeeding education given to women who had normal vaginal and cesarean delivery on breastfeeding self-efficacy and breastfeeding success.

METHODS

This is a pretest-posttest randomized controlled quasi-experimental study. This study included 76 women (38 intervention group and 38 control group) who gave birth in a women's and children's diseases training and research hospital.ClinicalTrials.gov Identifier: NCT05666817. The data were collected by means of the introductory information form, breastfeeding knowledge level diagnosis form, LATCH scale, and postnatal self-efficacy scale. In the evaluation of the data, independent group t-tests and dependent group t-tests were used.

RESULTS

Research findings indicate that the women's breastfeeding knowledge level, LATCH scale, and postnatal breastfeeding self-efficacy scale scores were statistically higher than the control group in the post-test (p<0.05).

CONCLUSION

It was found by the researchers that postnatal breastfeeding education is effective in increasing the level of breastfeeding knowledge, breastfeeding success, and breastfeeding self-efficacy.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Weekly Proactive Telephone Breastfeeding Standard Care by Lactation Consultants in the First Month Postpartum Prolongs Breastfeeding for Up to 6 Months

Many mothers, especially those with co-morbidities, do not achieve exclusive breastfeeding (EBF) for the first 6 months, with the loss of multiple health benefits including enhanced infant nutrition. We wished to evaluate whether proactive lactation consultant telephone advice in the first month postpartum improved breastfeeding rates for up to 6 months. A prospective cohort observational study was performed. Mother groupings included the following: Control (CG, n = 379)-standard postnatal care; Exposure (EG, n = 386)-standard postnatal care delivered by lactation consultant telephone contact for the first 3 weeks postpartum and then follow-up calls at 1, 3 and 6 months postpartum to ascertain breastfeeding status. Sore nipples (24%) and fussy/unsettled behaviour (14-19%) were common EG concerns. EG EBF rates were higher at 1 month (65% vs. 53%; p < 0.001), 3 months (57% vs. 49%; p = 0.041) and 6 months (45 vs. 33%; p < 0.001). EG EBF rates across the 6 months were higher for infants admitted to the NNU (52.9% vs. 37.5%, p = 0.003), obese mothers (58.3% vs. 37.2%, p < 0.001), mothers with depression (60.8% vs. 43.4%, p = 0.036) and all birth modes. Proactive early lactation advice significantly prolongs EBF and consequently enhances infant nutrition overall, including for mothers at risk of early breastfeeding cessation.

The relationship between women's breastfeeding empowerment and conformity to feminine norms

BACKGROUND

Women empowerment is effective in successful breastfeeding. Hence,identifying the relationship between psychosocial factors, such as acceptance of feminine norms, and empowerment can be beneficial in designing interventions.. Therefore, this study aimed to determine the relationship between breastfeeding empowerment and conformity to feminine norms.

METHODS

This cross-sectional study was conducted on 288 primiparous mothers in the postpartum period using validated questionnaires of conformity to gender norms and breastfeeding empowerment in the following domains: "sufficient knowledge and skills for breastfeeding," "a sense of breastfeeding competence," "conscious belief in the value of breastfeeding," "overcoming breastfeeding problems," "negotiation and obtaining family support" and "self-efficacy in breastfeeding" which were completed through the self-report method. Data were analyzed using the multivariate linear regression test.

RESULTS

The mean score of 'conformity to feminine norms' and 'breastfeeding empowerment' were 142.39 and 144.14, respectively. The score of breastfeeding empowerment was positively related to conformity to feminine norms (p = 0.003). Among the dimensions of breastfeeding empowerment, 'mothers' adequate knowledge and skills for breastfeeding' (p = 0.001), 'belief in the value of breastfeeding' (p = 0.008), and 'negotiation and obtaining family support' (p = 0.01) were positively related to conformity to feminine norms.

CONCLUSIONS

The results indicate a positive relationship between the level of conformity to feminine norms and breastfeeding empowerment. Accordingly, it is recommended that supporting breastfeeding as a valuable role of women be considered in programs designed to improve breastfeeding empowerment.

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.

Effects of relaxation therapy on maternal psychological status and infant growth following late preterm and early-term delivery: a randomized controlled trial

BACKGROUND

Maternal stress is one modifiable variable that could influence mother-infant signaling and negatively affect breastfeeding and infant growth.

OBJECTIVES

This study aimed to test the hypothesis that relaxation therapy would reduce maternal stress and improve infant growth, behavior, and breastfeeding outcomes after late preterm (LP) and early-term (ET) delivery.

METHODS

A single-blind randomized controlled trial was conducted in healthy Chinese primiparous mother-infant pairs after LP or ET delivery (34⁺⁰-37⁺⁶ gestation weeks). Mothers were randomly assigned to the intervention group (IG, listening to relaxation meditation at least once a day) or control group (CG, normal care). Primary outcomes-changes in maternal stress (perceived stress scale), anxiety (Beck Anxiety Inventory), and infant weight and length standard deviation score-were assessed at 1 wk and 8 wks postpartum. Secondary outcomes-breast milk energy and macronutrient composition, maternal breastfeeding attitudes, infant behaviors (3-d diary), and 24-hour milk intake-were assessed at 8 wks.

RESULTS

In total, 96 mother-infant pairs were recruited. There was a significantly greater reduction in maternal perceived stress (Perceived Stress Scale score) (mean difference [MD] = 2.65; 95% CI: 0.8, 4.5) and significantly greater infant weight standard deviation score gain (MD = 0.51; 95% CI: 0.2, 0.9) from 1 wk to 8 wks in the IG than those in the CG. Exploratory analyses showed a significant interaction between intervention and sex, with greater effects on weight gain in female infants. Mothers of female infants used the intervention more frequently with significantly higher milk energy observed at 8 wks.

CONCLUSIONS

The relaxation meditation tape is a simple, effective practical tool that could easily be used in clinical settings to support breastfeeding mothers after LP and ET delivery. The findings need confirmation in larger groups and in other populations.

Prevalence of and factors associated with postnatal depression and anxiety among parents of preterm infants: A systematic review and meta-analysis

BACKGROUND

This study aimed to determine the prevalence of and factors associated with postpartum depression and anxiety among mothers and fathers of preterm infants and to examine the relationships between maternal and paternal symptoms.

METHODS

Six electronic databases were searched to identify eligible studies reporting parental depression and anxiety within 1 year postpartum. Data were extracted for a random-effects meta-analysis to estimate the prevalence with 95 % confidence intervals (CIs). Subgroup and meta-regression analyses were conducted to analyze associations between study characteristics and prevalence estimates.

RESULTS

In total, 79 studies were included. The meta-analysis of studies on mothers generated estimates of prevalence for depression (29.2 %, 95 % CI, 21.8 %-37.9 %) and anxiety (37.7 %, 95 % CI, 24.1 %-53.6 %). The meta-analysis of fathers indicated a pooled depression prevalence of 17.4 % (95 % CI, 12.5 %-23.8 %) and an anxiety estimate of 18.3 % (95 % CI, 8.1 %-36.3 %). Assessment time points and methods as well as the geographic continent in which the study was conducted were significant moderators of depression and anxiety. Significant inter-correlations were found between mothers' and fathers' depression and anxiety symptoms (p < 0.05).

LIMITATIONS

Limited data from specific geographic continents, including Africa and Asia.

CONCLUSIONS

Prevalence of depression and anxiety among preterm infants' parents was high, highlighting the need for early psychological screening and assessment. Further research is required to improve services that focus on parents' postpartum psychological needs in the family context.

Obesity-derived alterations in the lactating mammary gland: Focus on prolactin

Obesity is a modern pandemic with negative consequences in women's reproductive health. Women with overweight and obesity can develop mammary gland alterations that unable exclusive breastfeeding. Obesity associates with a disturbed lactating mammary gland endocrine environment including a decreased action of the hormone prolactin (PRL), the master regulator of lactation. The PRL receptor and the action of PRL are reduced in the mammary gland of lactating rodents fed an obesogenic diet and are contributing factors to impaired lactation in obesity. Also, treatment with PRL improves milk yield in women with lactation insufficiency. This review focuses on the impact of diet-induced obesity in the lactating mammary gland and how obesity impairs the lactogenic action of PRL. Although obesity alters lactation performance in humans and rodents, the responsible mechanisms have been mainly addressed in rodents.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

The possible mediating relationship promoted by the self-efficacy of breastfeeding associated with the Kangaroo Method on indicators of exclusive breastfeeding

OBJECTIVE

Assess the mediating role of breastfeeding self-efficacy in the association between the Kangaroo Neonatal Intermediate Care Unit and exclusive breastfeeding.

METHOD

Cross-sectional study nested in a cohort, carried out in the Neonatal Unit of a Brazilian university hospital between September 2018 and March 2020. The sample consisted of 114 newborns weighing ≤1800 g and their mothers who were divided into those who participated in the first and second stages of the Kangaroo Method and those who only passed through the first stage, categorized as the Conventional group. To assess the self-efficacy of breastfeeding, the Breastfeeding Self Efficacy Scale - Short-Form was used. The Mann-Whitney test was used to compare the breastfeeding self-efficacy score between the groups, and Fisher's exact test to compare rates of exclusive breastfeeding. The adjusted structural equation model was used to check for the mediating effect of breastfeeding self-efficacy. The significance level adopted was 5%.

RESULTS

The kangaroo group had a higher rate of exclusive breastfeeding at hospital discharge (p = 0.000). There was a positive association between having remained in the kangaroo (p = 0.003) and the breastfeeding self-efficacy score (p = 0.025) with the rate of exclusive breastfeeding at hospital discharge. Breastfeeding self-efficacy did not act as a mediator.

CONCLUSION

The self-efficacy of breastfeeding and the stay of the low birth weight newborn baby in the kangaroo unit acted positively and independently in exclusive breastfeeding, and the self-efficacy of breastfeeding did not act as a mediator in this association.

Behaviour, Attitudes and Knowledge of Healthcare Workers on Breastfeeding

The aim of this paper is to determine the current state of behavior, attitudes, and knowledge of health professionals about breastfeeding in Croatia. Data were collected via a breastfeeding behavior, attitudes, and knowledge questionnaire, which has already been validated and used in Croatia. The secondary aim is to identify differences in outcomes of respondents by occupation (nurses versus others health professionals). In the study, 374 health professionals participated (37 males and 337 females). Respondents completed the questionnaire online. Respondents were rarely involved in breastfeeding education. On the behavior scale, the worst answer was given to the question of advising mothers on breastfeeding after 24 months. On the attitude scale, the worst result was achieved in terms of public breastfeeding and the support of the child's father for the breastfeeding mother. Respondents demonstrated the worst knowledge of The International Code of Marketing of Breast-milk Substitutes and the use of medications while breastfeeding. There was no statistically significant difference between the results of respondents in relation to the occupation of the respondents. In the preparation of future breastfeeding education for health professionals in Croatia, particular attention should be given to these issues.

Assessment of Aluminum via Baby Foods Consumption in Turkey: Estimated Early-Life Dietary Exposure and Target Hazard Quotient

This study focuses on infant formulas and baby biscuits, which have an important place in the nutrition of the most vulnerable individuals, namely babies. In this sense, the aluminum levels of 64 different baby foods, retrospectively consumed by 348 babies for dietary recall 24 h, were determined by ICP-MS. Then, the exposure resulting from the consumption of these foods was calculated via a deterministic model, and a risk assessment was made. Aluminum levels of infant formulas and baby biscuits that are of higher values compared to other studies were found in the range of 718-6987 and 1803-15,479 μg/kg, respectively. Aluminum exposure was calculated as 8.02, 7.28, 4.03, and 4.08 μg/kg bw/day in babies aged 0-6, 7-12, 13-24, and 25-36 months, respectively. There is no statistically significant difference between different age groups according to the total aluminum exposure levels. The toxicological contribution of aluminum exposure is quite limited (< 6.0% of PTWI). THQ values were calculated as 10-20 for babies aged 0-36 months. Therefore, THQ values indicate a potential health problem.

The role of skin-to-skin contact in exclusive breastfeeding: a cohort study

OBJETIVE

To understand the role of exposure to skin-to-skin contact and its minimum duration in determining exclusive breastfeeding at hospital discharge in infants weighing up to 1,800g at birth.

METHODS

A multicenter cohort study was carried out in five Brazilian neonatal units. Infants weighing ≤ 1,800g at birth were eligible. Skin-to-skin contact time was recorded by the health care team and parents on an individual chart. Maternal and infant data was obtained from maternal questionnaires and medical records. The Classification Tree, a machine learning method, was used for data analysis; the tree growth algorithm, using statistical tests, partitions the dataset into mutually exclusive subsets that best describe the response variable and calculates appropriate cut-off points for continuous variables, thus generating an efficient explanatory model for the outcome under study.

RESULTS

A total of 388 infants participated in the study, with a median of 31.6 (IQR = 29–31.8) weeks of gestation age and birth weight of 1,429g (IQR = 1,202–1,610). The exclusive breastfeeding rate at discharge was 61.6%. For infant’s weighting between 1,125g and 1,655g, exposed to skin-to-skin contact was strongly associated with exclusive breastfeeding. Moreover, infants who made an average > 149.6 min/day of skin-to-skin contact had higher chances in this outcome (74% versus 46%). In this group, those who received a severity score (SNAPPE-II) equal to zero increased their chances of breastfeeding (83% versus 63%).

CONCLUSION

Skin-to-skin contact proved to be of great relevance in maintaining exclusive breastfeeding at hospital discharge for preterm infants weighing 1,125g–1,655g at birth, especially in those with lower severity scores.

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

Background

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

Methods

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

Results

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

Conclusion

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

Cesarean section and breastfeeding outcomes in an Indigenous Qom community with high breastfeeding support

BACKGROUND AND OBJECTIVES

Cesarean section may lead to suboptimal breastfeeding outcomes, though evidence has been mixed. Factors, such as premature birth, birth weight and maternal age may independently increase risk of cesarean and hinder breastfeeding initiation, while maternal preferences, support and sociostructural barriers may influence breastfeeding practices beyond the immediate postpartum period.

METHODOLOGY

We assessed impacts of cesarean section and gestational factors on breastfeeding duration among Indigenous Qom mothers in Argentina who have strong traditional breastfeeding support. We modeled transitions from exclusive breastfeeding to complementary feeding and from complementary feeding to full weaning in a Bayesian time-to-event framework with birth mode and gestational covariates (n = 89 infants).

RESULTS

Estimated median time to full weaning was 30 months. Cesarean-delivered babies were weaned an average of 5 months later adjusting for gestational age, maternal parity and infant sex. No factors were associated with time-to-complementary feeding, and time-to-complementary feeding was not associated with time-to-full weaning.

CONCLUSIONS AND IMPLICATIONS

Among Indigenous Qom mothers in Argentina, cesarean section was not associated with suboptimal breastfeeding outcomes. Although some Qom mothers do experience early breastfeeding problems, particularly following first birth, problems are not more frequent following cesarean delivery. Traditional postpartum kin and community support during prolonged postpartum periods may be instrumental in helping mothers to overcome early breastfeeding problems due to cesarean or other risk factors.

Exclusive breastfeeding of full-term infants during the first 6 months after discharge from a neonatal unit in China: A cross-sectional study

OBJECTIVES

To elucidate breastfeeding patterns, the reasons for stopping exclusive breastfeeding, and the sociodemographic characteristics associated with exclusive breastfeeding of full-term infants during the 6 months after discharge from a neonatal unit in China.

METHODS

This cross-sectional study included mothers of full-term infants who were discharged from the 40-bed neonatal unit (level IIA) of a tertiary hospital in Hunan province, China between August 2019 and September 2020. Information on breastfeeding patterns was collected through telephone interviews with the mothers 6 months after their infants had been discharged from the neonatal unit. Binary logistic regression was used to determine the factors associated with exclusive breastfeeding.

RESULTS

This study included 489 mother-infant dyads. At 6 months after discharge, 51.5% of mothers were exclusively breastfeeding, 29.0% of mothers were partially breastfeeding, and 19.4% of mothers were not breastfeeding. The most common reason for stopping breastfeeding was "poor milk supply" (81.2%). Factors associated with exclusive breastfeeding included multiparity, exclusive breastfeeding before the hospitalization, providing breast milk to the hospitalized infant, and a high level of maternal education.

CONCLUSIONS

In the Chinese culture, mothers who experienced multiparity and higher-level education were more likely to breastfeed their infants to 6 months after discharge from the neonatal unit. In addition, infants who were exclusively breastfed before and during hospitalization were also more likely to be exclusively breastfed after discharge. The results will help inform future research aimed at identifying interventions to reduce early breastfeeding cessation.

Duration of Breastfeeding in Late Preterm Infants: Maternal and Infant Factors

BACKGROUND

More than 550,000 late preterm infants are born each year in Indonesia. These infants, born between 34^0/7-36^6/7 weeks, have more complications than term infants. Breastfeeding is considered the most optimal nutrition for newborn infants. Two groups of factors are important for successful breastfeeding: infant and maternal factors. The infant factors can be evaluated using the Infant Breastfeeding Assessment Tool and the maternal aspects with the Breastfeeding Self-Efficacy Scale-Short Form.

AIM

To determine whether the Infant Breastfeeding Assessment Tool or the Breastfeeding Self-Efficacy Scale-Short Form was more predictive of successful breastfeeding among late preterm infants.

METHODS

This study was conducted in the Academic Teaching Hospital in Surabaya, Indonesia in March-July 2017. Mothers who delivered their infant between a gestational age of 34^0/7 and 36^6/7 weeks were included.

RESULTS

Fifty-four single born participant mother-infant pairs were included. The mean total Breastfeeding Self-Efficacy Scale-Short Form score was 57.8 (SD = 8.9). The mean Infant Breastfeeding Assessment Tool score was 8.3 (SD = 1.8). There was a significant correlation between the total Breastfeeding Self-Efficacy Scale-Short Form score and the Infant Breastfeeding Assessment Tool score (p = .020, r = 0.316). The Breastfeeding Self-Efficacy Scale-Short Form was significantly higher in the participant (mothers) of the infants breastfed ≥ 4 months, compared to < 4 months, 61.59 (SD = 5.78) versus 51.78 (SD = 11.64; p = .001). No correlation was found between the duration of breastfeeding and Infant Breastfeeding Assessment Tool score (p = .087).

CONCLUSION

Maternal factors were more important for successful breastfeeding in these late preterm infants than infant factors in our sample.

Effect of continuous supportive telephone counselling on improving breastfeeding self-efficacy in mothers with late preterm infants four months after discharge: A randomized, controlled study

BACKGROUND

Breastfeeding self-efficacy is an important motivational factor in the continuity of lactation in mothers with preterm infants.

OBJECTIVE

The study aimed to determine the effect of continuous supportive telephone counselling on improving breastfeeding self-efficacy in mothers with late preterm infants.

MATERIAL AND METHODS

This randomized, controlled study was carried out with 65 eligible mothers (control n = 32, intervention n = 33) recruited in Ahvaz, Iran, in 2020. The eligible women were allocated into two groups- intervention and control-according to the block design. Data were measured monthly up to four months after discharge using the Dennis Breastfeeding Self-Efficacy Questionnaire. The control group received only routine care. Continuous supportive telephone counselling was provided for the intervention group members daily for 14 days after neonatal discharge. Data were analyzed using chi-square, repeated measures analysis of variance, independent t-test, and paired t-test at the significant level of 0.05. Statistical analysis was performed using the SPSS 16.0 software (SPSS Inc., Chicago, IL, USA).

RESULTS

The overall score in breastfeeding self-efficacy showed a statistically significant difference between the two study groups during the four months after discharge compared to the pre-intervention stage (P = 0.001). In the intervention group, the mean score of breastfeeding self-efficacy increased from 33.18 to 53.48, and in the control group it decreased from 31.17 to 28.56.

CONCLUSION

The results showed that continuous supportive telephone counselling can improve breastfeeding self-efficacy in mothers with preterm infants. The approach seems to be an acceptable basis for designing intervention programs in this field.

Influence of patterns of neonatal transfers on breastfeeding outcomes

AIM

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

METHODS

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

RESULTS

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

CONCLUSION

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

Maternal postpartum depression: risk factors, impacts, and interventions for the NICU and beyond

PURPOSE OF REVIEW

Postpartum depression (PPD) negatively impacts caregivers, infants, siblings, and entire families. Mothers with infants admitted to the neonatal intensive care unit (NICU) face additional risk for PPD, coupled with risk factors extending beyond a NICU admision. The novelty of this review is the focus on maternal PPD for mothers with infants admitted to the NICU. Interventions aimed at limiting and preventing PPD in this population include: prenatal and postpartum depression screening, PPD symptom awareness and monitoring, and trauma-informed care.

RECENT FINDINGS

PPD, the most frequent complication of childbirth, affects approximately 10-15% of mothers worldwide. Prevalence rates increase to 40% for mothers whose infant is admitted to the NICU. PPD can affect maternal and child health across the life course and predispose future generations to a myriad of developmental, psychosocial, and physical challenges. Prevalence rates are higher for racial and ethnic minorities, immigrant and refugee populations, and mothers in rural locations. Trauma-informed care is suggested at individual and organizational levels, leading to better care for those with and without previous trauma exposure.

SUMMARY

Increasing PPD symptom awareness, screening for PPD, and connections with resources should begin during prenatal visits. Care teams should discuss barriers to resources for mothers, children, and families to improve access and support.

Maternity ward staff perceptions of exclusive breastfeeding in Finnish maternity hospitals: A cross-sectional study

INTRODUCTION

This study aimed to describe exclusive breastfeeding (EBF, Step 6 of the Baby-Friendly Hospital Initiative) in Finnish maternity hospitals and identify factors that promote or limit EBF.

METHODS

A cross-sectional study design was used, and data were collected from eight maternity hospitals in Finland during a 10-day period in May 2014. The staff completed questionnaires (n=1554) from separate work shifts. The data were analyzed using descriptive statistics, and chi-squared and Fisher's tests. Responses to open-ended questions were analyzed using content analysis.

RESULTS

Maternity ward staff reported that 72% (n=1105) of the infants were exclusively breastfed during their work shift. The strongest promoting factors of exclusive breastfeeding were: maternity ward staffs' profession and education in breastfeeding counselling; multiparity; vaginal delivery; early skin-to-skin contact between mother and infant; initial breastfeeding after birth; rooming-in; and initial success of breastfeeding. The use of a nipple shield, the need for additional breastfeeding counselling, and infants' blood tests were limiting factors to exclusive breastfeeding. Open-ended answers revealed that exclusive breastfeeding was mainly delayed because of medical issues for the mother or infant.

CONCLUSIONS

Finnish maternity hospitals could improve exclusive breastfeeding rates by focusing attention and resources on breastfeeding counselling and evidence-based maternity care practices related to immediate care after birth, promoting vaginal delivery, rooming-in and availability of skilled counselling.

Positive Effects of Kangaroo Mother Care on Long-Term Breastfeeding Rates, Growth, and Neurodevelopment in Preterm Infants

Background and Objectives: Kangaroo mother care (KMC) benefits preterm infants' health through increasing breastfeeding, but the longitudinal effects of KMC remain unknown. This study investigates the impact of KMC on breastfeeding and health outcomes in Chinese preterm infants. Methods: A longitudinal randomized controlled study was conducted with 79 preterm infant-mother dyads. The KMC group (n = 36) was provided 2.5 hours/day KMC during the neonatal intensive care unit (NICU) hospitalization, while the control group (n = 43) received standard care. Infant's feeding regimens and physical growth were documented daily at NICU. Physical growth and Neonatal Behavioral Neurological Assessment were measured at 40 weeks, 3 months, and 6 months of corrected age (CA). Breastfeeding outcomes were documented at 6 months of CA. Results: Compared with the control group, KMC infants received higher mothers' milk proportion during hospitalization (B = 0.16, confidence interval [CI] = [0.11-0.21]) and less feeding intolerance at discharge (odds ratio [OR] = 0.11, CI = [0.02-0.43]); and higher exclusive breastfeeding proportion (OR = 14.6, CI = [3.5-60.9]) at 6 months CA. KMC infants also had significant increased body weight and body length at hospital discharge; and more increases of body weight, body length, and head circumference in follow-ups. The neurobehavioral score was also higher in the KMC group compared to the control group over time. Conclusions: Longitudinal KMC effects are significant in promoting preterm infants' breastfeeding outcomes, growth, and neurodevelopment. Early initiation of KMC practice is highly recommended to the parent-infant population in Chinese NICUs to promote breastfeeding and developmental outcomes.

Home-based nursing for improvement of quality of life and depression in patients with postpartum depression

BACKGROUND

Postpartum depression is a common mental illness in puerpera, with an incidence of approximately 3.5%-33.0% abroad, and the incidence of postpartum depression in China is higher than the international level, reaching 10.0%-38.0%. Providing effective nursing care in clinical nursing activities is one of the key points of obstetrical care. However, little research has been designed to investigate the positive role of home-based nursing in the prevention of postpartum depression .

AIM

To study the effect of home-based nursing for postpartum depression patients on their quality of life and depression.

METHODS

The clinical data of 92 patients with postpartum depression treated at our hospital were retrospectively analyzed. The patients were grouped according to the nursing methods used; 40 patients receiving basic nursing were included in a basic nursing group, and 52 receiving home-based nursing were included in a home-based nursing group. Depression and anxiety were evaluated and compared between the two groups. The estradiol (E2), serotonin (5-hydroxytryptamine, 5-HT), and progesterone (PRGE) levels were measured.

RESULTS

The SAS and SDS scores of the home-based nursing group were significantly lower than those of the basic nursing group (P < 0.05). The E2 and 5-HT levels of the home-based nursing group were significantly higher than those of the basic nursing group, but the PRGE level was significantly lower than that of the basic nursing group. The GQOLI-74 scores (material, social, somatic, and psychological) and nursing satisfaction were significantly higher in the home-based nursing group (P < 0.05).

CONCLUSION

Postpartum depression through home-based nursing can effectively alleviate depression and improve the quality of life of patients, help modulate their serum E2, 5-HT, and PRGE levels, and improve their satisfaction with nursing care.

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

OBJECTIVE

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

DESIGN

A cross-sectional study was conducted.

SETTING

Two tertiary hospitals in China.

PARTICIPANTS

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

MEASUREMENTS

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

FINDINGS

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

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

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

Predictors of exclusive breastfeeding practice among migrant and non-migrant mothers in urban China: results from a cross-sectional survey

OBJECTIVE

To explore and compare the predictors for exclusive breast feeding (EBF) among migrant and non-migrant mothers in China.

DESIGN

A large-scale cross-sectional study.

SETTING

12 counties/districts were covered in China.

PARTICIPANTS

A total number of 10 408 mothers were recruited, of whom 3571 mothers of infants aged 0-5 months in urban China were used for analysis.

OUTCOME

The practice of EBF was calculated based on the foods and drinks consumed in the last 24 hours, as recommended by WHO.

RESULTS

Around 30% of Chinese mothers with infants aged 0-5 months practised EBF in urban areas, with no significant difference between migrant and non-migrant mothers (p=0.433). Among the migrant mothers, factors associated with EBF included residence in big cities (adjusted OR, AOR 1.68 (95% CI 1.20 to 2.34)), premature birth (AOR 0.27 (95% CI 0.09 to 0.81)), knowledge about EBF (AOR 2.00 (95% CI 1.51 to 2.65)), low intention of breast feeding in the first month postpartum (AOR 0.59 (95% CI 0.36 to 0.97)) and mothers working in agriculture-related fields or as casual workers (AOR 1.77 (95% CI 1.18 to 2.64)). Among non-migrant mothers, in addition to similar predictors including residence in big cities (AOR 1.40 (95% CI 1.13 to 1.73)), knowledge about EBF (AOR 1.25 (95% CI 1.02 to 1.53)) and low intention of breast feeding in the first month post partum (AOR 0.46 (95% CI 0.31 to 0.70)], early initiation of breast feeding (EIBF) (AOR 1.78 (95% CI 1.35 to 2.33)) and caesarean delivery (AOR 0.74 (95% CI 0.60 to 0.89)) were also factors associated with EBF.

CONCLUSIONS

There was no significant difference in the prevalence of EBF between migrant and non-migrant mothers in urban China. Premature birth and maternal occupation in agriculture-related fields or casual work were distinctive factors associated with EBF for migrants, while EIBF and caesarean delivery were unique predictors for non-migrants.

Intermittent kangaroo mother care and the practice of breastfeeding late preterm infants: results from four hospitals in different provinces of China

BACKGROUND

China has an extremely low exclusive breastfeeding rate. Kangaroo mother care (KMC) has been shown to increase the exclusive breastfeeding rate among infants born extremely or very preterm. However, there is limited evidence surrounding intermittent KMC and exclusive breastfeeding in late preterm infants. In our study we investigated the association between the provision of intermittent KMC and breastfeeding practice for late preterm infants in four hospitals in different provinces of China.

METHODS

Intermittent KMC was recommended to the mothers of all preterm infants admitted to the postnatal wards of participating hospitals between March 2018 and March 2019. Those who agreed to practice KMC were enrolled in the "KMC group", those who did not were enrolled in the "No KMC group". Basic maternal socio-demographic information was collected, feeding practice; outcome and method, were recorded daily whilst in hospital. A follow-up survey of feeding practice was conducted 42 days after discharge. Calculations for feeding practice were performed separately for both groups. Logistics regression was used to analyze the association between KMC and feeding outcome and method, adjusting for socio-demographic covariates.

RESULTS

Among the 844 mothers participating in the study, 627 (74.3%) chose to perform KMC. More of the mothers who provided KMC were exclusively breast milk feeding their infants in the 24 h before hospital discharge (54.6%) and at follow-up (57.3%), compared to mothers who did not provide KMC (34.6% at discharge and 33.2% at follow-up,). Mothers in the KMC group were more likely to be breastfeeding (method) than mothers in the No KMC group (65.3% vs. 52.1% at discharge, and 83.1% vs. 67.3% at follow up). Logistic regression indicated that compared with the No KMC group, mothers who provided KMC were twice as likely to be exclusively breast milk feeding their infants at discharge (OR = 2.15 (95% CI 1.53, 3.02)), use breastfeeding method at discharge as opposed to other means such as bottle or cup feeding (OR = 1.61 (95% CI 1.15, 2.25)), be exclusive breast milk feeding at follow-up (OR = 2.55 (95% CI 1.81, 3.61)), and use breastfeeding method at follow-up (OR = 2.09 (95% CI 1.44, 3.02)).

CONCLUSIONS

Intermittent KMC was associated with a nearly doubled increase in exclusive breast milk feeding (outcome) and breastfeeding (method) at both discharge and 42 days after discharge for late preterm infants. This is especially important in China where exclusive breastfeeding rates are low, intermittent KMC provides a feasible means to increase the likelihood of these vulnerable infants receiving the benefits of exclusive breastmilk.

Parity and the Association Between Maternal Sociodemographic Characteristics and Breastfeeding

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

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

BACKGROUND

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

PURPOSE

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

METHODS

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

RESULTS

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

IMPLICATION FOR PRACTICE

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

IMPLICATION FOR RESEARCH

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

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

BACKGROUND

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

AIMS AND OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSION

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

RELEVANCE TO CLINICAL PRACTICE

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

Explaining breastfeeding experiences and assessing factors affecting breastfeeding self-efficacy in mothers of premature infants: a mixed method study protocol

BACKGROUND

Breastfeeding has a great effect on health promotion and disease prevention in premature infants. However, various factors affect the success of breastfeeding process in mothers. The present study aims to: a) explain breastfeeding experiences; b) assess the factors affecting breastfeeding self-efficacy; and c) present a guideline for promoting breastfeeding in mothers of premature infants.

METHODS

This mixed-methods study with a sequential explanatory design consisted of three phases. The first phase is qualitative study to explore the breastfeeding experiences in mothers of premature infants. In this phase, the subjects will be selected through purposive sampling; moreover, in-depth individual interviewing will be used for data collection. Finally, the conventional content analysis approach will be employed for data analysis. The second phase is quantitative and will be used a cross-sectional approach to assess the association of the social determinants of health with breastfeeding self-efficacy in mothers of premature infants. In this phase, the multistage cluster sampling method will be used to select 360 subjects who will be visited healthcare centers in Tabriz, Iran. The third phase focused on developing strategies to increase the ability of mothers to breastfeed their premature infants, using the qualitative and quantitative results of previous phases, a review of the related literature, and the nominal group technique will be performed among experts.

DISCUSSION

The present research is the first study that investigated the experiences of breastfeeding and factors influencing breastfeeding self-efficacy in mothers of premature infants. For the purposes of the study, the mixed methods approach will be used which aimed to develop strategies for the improvement of healthcare services in this regard. It is worth noting that there is no strategic guideline in Iran's healthcare system for the improvement of breastfeeding, especially regarding mothers of premature infants. Therefore, it is hoped that the strategy proposed in the current study can lead to improvements in this regard.

Breastfeeding experiences and perspectives on support among Chinese mothers separated from their hospitalized preterm infants: a qualitative study

Background

Chinese mothers of preterm infants often face obstacles to breastfeeding and commonly experience prolonged maternal-infant separation when their high-risk infants are hospitalized in a Neonatal Intensive Care Unit (NICU). This separation hinders mother-infant attachment and the establishment of breastfeeding. Currently, little is known about Chinese mothers’ experiences breastfeeding their preterm infants, or their support needs. The aim of this study was to develop an understanding of mothers’ experiences breastfeeding a hospitalized preterm infant and the support needed to establish a milk supply during the period separation from their infants.

Methods

A qualitative descriptive study was conducted in Beijing in 2017. A total of 11 Chinese mothers were individually interviewed while separated from their infants. The interviews were audio-recorded and transcribed verbatim. A thematic analysis involving a seven-step protocol identified key themes.

Results

Mothers of preterm infants reported physically and mentally challenging breastfeeding experiences during the period they were separated from their babies. They viewed expressing breast milk as integral to their maternal role, even though some found expressing breastmilk exhausting. With little professional support available, the mothers depended upon nonprofessionals to establish breastfeeding.

Conclusions

The study identified the difficulties mothers experienced establishing a milk supply while separated from their preterm infants, and the importance of access to health professional support.

Breastmilk Pumping for the Mental Health of the NICU Mother

Objective

While much is known about breastfeeding and postpartum depression, little is known about breast milk pumping's impact on postpartum depression among mothers with infants in the neonatal intensive care unit (NICU).

Methods

Thirty-two mothers of infants admitted to a Level III NICU between February and July 2017 were screened for postpartum depression using the Edinburgh Postnatal Depression Scale (EPDS). They were also surveyed for current breastmilk pumping activities and demographic factors. Multivariable logistic regression was used to assess the associations between postpartum depression and breast milk pumping, adjusting for confounding variables.

Results

After controlling for confounding variables, mothers who did not pump breast milk (relative to mothers who did) were 11 times more likely to have lower EPDS depression scores indicative of probable postpartum depression (OR = 11.7, p-value .05).

Conclusions

Our results suggest a significant reduction in probable postpartum depression among NICU mothers who express breastmilk.
