Main Biopsychosocial Factors Influencing Breastfeeding: a Systematic Review

Investigating the association between labor pain and cessation of breastfeeding

Mothers encounter several challenges to sustain breastfeeding until the recommended 6 months of age. There is limited evidence on the impact of women's labor pain experiences upon cessation of breastfeeding. We aimed to investigate the association between women's labor pain experiences, intrapartum interventions, and pre-birth psychological vulnerabilities and cessation of breastfeeding. This was a secondary analysis of a clinical trial conducted in a tertiary hospital in Singapore between June 2017 and July 2021. Data were obtained from participants, electronic records and surveys administered before delivery, and postpartum 6-10 weeks. A total of 624 (76.8%) women were still breastfeeding at postpartum 6-10 weeks as compared to 189 (23.2%) that had discontinued breastfeeding. Multivariable regression analysis identified lower education level (aOR 3.88, 95% CI 2.57-5.85, p < 0.0001), having diabetes (aOR, 95% CI 1.21-5.44, p = 0.0141), presence of obstetric complications (aOR 1.57, 95% CI 1.00-2.46, p = 0.0494), artificial rupture of membrane (ARM) and oxytocin induction (aOR 2.07, 95% CI 1.22-3.50, p = 0.0068), lower age (aOR 0.92, 95% CI 0.88-0.97, p = 0.0010) and higher A-LPQ birth pain score (aOR 1.02, 95% CI 1.01-1.04, p = 0.0064) as independent associations with cessation of breastfeeding at postpartum 6-10 weeks, with AUC of the model being 0.72 (95% CI 0.68-0.77). Higher pain experienced during labor is associated with cessation of breastfeeding among several other intrapartum interventions and psychological vulnerabilities. Using risk stratification strategy, breastfeeding support services could be provided to women to optimize successful breastfeeding in the postpartum period.Trial registration: This study was registered on Clinicaltrials.gov NCT03167905 on 30/05/2017.

Influence of social media on maternal decision-making and breastfeeding practices

Breastfeeding practices are influenced by multifactorial determinants including individual characteristics, external support systems, and media influences. This commentary emphasizes such complex factors influencing breastfeeding practices. Potential methodological limitations and the need for diverse sampling in studying breastfeeding practices are highlighted. Further research must explore the interplay between social influences, cultural norms, government policies, and individual factors in shaping maternal breastfeeding decisions.

Role of Human Milk Microbiota in Infant Neurodevelopment: Mechanisms and Clinical Implications

BACKGROUND

Human milk (HM) is recognized as an ideal source of nutrition for newborns; as a result, its multiple bioactive molecules can support the growth of healthy newborns and reduce the risk of mortality and diseases such as asthma, respiratory infections, diabetes (type 1 and 2), and gastrointestinal disorders such as ulcerative colitis and Crohn's disease. Furthermore, it can reduce the severity of necrotizing enterocolitis (NEC) in preterm infants. Moreover, human milk oligosaccharides (HMOs) present in breast milk show an immunomodulatory, prebiotic, and neurodevelopmental effect that supports the microbiota-gut-brain axis.

MATERIAL AND METHODS

This study examined the state-of-the-art research, using keywords such as "breastfeeding", "human milk oligosaccharides", "microbiota-gut-brain axis", "infants", and "malnutrition". The literature review was conducted by selecting articles between 2013 and 2024, as the most recent ones. The databases used were Web Science, PubMed, and Scopus.

RESULTS

We found multiple studies examining the composition of HM and infant formula (IF). However, further longitudinal studies and randomized control trials (RCTs) are needed to better understand the clinical outcomes that bioactive components exert on healthy and hospitalized children and how, in conditions of malnutrition, it is necessary to support the growth of the newborn.

CONCLUSIONS

In this review, we affirm the importance of human milk and, through it, the modulation of the microbiota and the neuroprotective role in newborns, determining the health of the following years of life.

Trajectories of Breastfeeding-Related Thoughts and Attitudes Among Low-Income Smoke-Exposed Pregnant Women: A Latent Class Growth Analysis

BACKGROUND

Psychosocial predictors of breastfeeding and changes in those factors during pregnancy, along with the relationship of those changes with both breastfeeding and smoke use and exposure, are not well explored.

RESEARCH AIM

The aim of this study was to identify distinct trajectories of psychosocial determinants of breastfeeding and smoking in pregnant women.

METHODS

We used a longitudinal study design and data from a randomized controlled trial conducted among smoke-exposed pregnant women and their infants. Participants were recruited early in pregnancy and were surveyed at ≤ 16 and 32 weeks gestation, delivery, 3 and 6 months postpartum for breastfeeding intentions, initiation, continuation, and smoke use and exposure. Psychosocial variables associated with breastfeeding were measured at baseline and 32 weeks gestation using the Mitra index, a structured questionnaire that assesses barriers and facilitators of breastfeeding intentions. Latent class growth analysis was performed using Mitra scores to identify distinct subgroups of participants with different trajectories. Sociodemographic characteristics, breastfeeding, and tobacco smoke use and exposure were compared across classes.

RESULTS

Three or four trajectories were identified for each of the six Mitra scores. Trajectories for all Mitra scores were associated with breastfeeding intention and initiation. Overall, Mitra, knowledge, self-efficacy, social support, and time barrier classes all differed by tobacco smoke use or exposure.

CONCLUSION

Trajectories of breastfeeding knowledge, self-efficacy, social support, and time to breastfeed/social barriers are associated with tobacco smoke use and exposure during pregnancy. Encouragement to breastfeed and to cease and avoid tobacco smoke should start early in pregnancy, focusing on these determinants to improve health outcomes.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Breastfeeding Ability After Breast Reductions: What does the Literature Tell us in 2023?

INTRODUCTION

Reduction mammaplasties are routinely performed on women of child-bearing age, yet there still exists some uncertainty regarding a patient's ability to breastfeed following the procedure. This is due to inconsistent definitions of "successful" breastfeeding, a variety of pedicles implemented, and inadequate follow-up in the published literature. Our aim was to summarize the current data and provide clear recommendations for counseling patients on expected breastfeeding outcomes following reduction mammaplasty.

METHODS

A systematic review and meta-analysis in accordance with the PRISMA guidelines was conducted. We included papers that reported proportion of breastfeeding ability following reduction mammaplasty.

RESULTS

We identified 33 papers that met our inclusion criteria. We found that women who undergo reduction mammaplasty are at a 3.5 times increased odds of not being able to breastfeed compared to controls. Overall, reduction mammaplasty patients have a breastfeeding success rate of 62%. The breastfeeding success rate for patients with inferior pedicles was 64%, superior pedicles was 59%, and lateral pedicles was 55%. No conclusions could be drawn regarding medial, central, vertical, and horizontal pedicles on breastfeeding ability.

CONCLUSION

Current data suggest that women undergoing reduction mammaplasty have an increased odds of unsuccessful breastfeeding when compared to similar women who have not undergone the procedure. Based on the current literature, pedicle type does play a role in rate of breastfeeding success, although there is a need for further research on the aforementioned pedicles. Physicians should be aware of the likelihood of successful breastfeeding following reduction mammaplasty so that patients can be more thoroughly counseled prior to a decision for surgery.
