A randomised controlled trial evaluating the effect of a brief motivational intervention to promote breastfeeding in postpartum depression

A Scoping Review of Breastfeeding Interventions and Programs Conducted Across Spanish-Speaking Countries

Breastfeeding is vital to a child's lifelong health and has significant positive benefits to mother's health. World Health Organization recommends beginning exclusively breastfeeding within the first hour after birth and continuing during the first 6 months of infant's life. The purpose of this review is to identify and examine breastfeeding interventions conducted across the Spanish-speaking countries. A scoping review of the literature was conducted across 14 databases for relevant publications published through April 2023 to find studies in Spanish-speaking countries that involved breastfeeding as an intervention component. A total of 46 peer-reviewed articles were included in this review, across 12 Spanish-speaking countries. Participants ranged from pregnant women, mothers, mother-infant pair, and health care professionals. Intervention at the individual level in combination with support from trained health care professionals or peer counselors seemed to have higher improvements in breastfeeding rates. The greatest improvement in exclusively breastfeeding for 6 months was seen in interventions that included prenatal and postnatal intensive lactation education, for a period of 12 months. The most effective interventions that improved rates of any breastfeeding included promotional activities, educations workshop, and training of health care staff along with changes in hospital care. Breastfeeding promotion is an economical and effective intervention to increase breastfeeding behavior and thereby improving breastfeeding adherence across Spanish-speaking countries.

Breastfeeding and Postpartum Depression: A Review of Relationships and Potential Mechanisms

PURPOSE OF REVIEW

Postpartum depression (PPD) and breastfeeding are important, interrelated health factors. It is established that women who breastfeed exclusively have lowered likelihood of developing significant PPD. Yet, many questions remain around what factors are involved. The purpose of this review is to provide updated information about the relationship between PPD and breastfeeding.

RECENT FINDINGS

Both psychological and physiological factors have emerged as important moderators and mechanisms of the relationship between postpartum depression and breastfeeding. Breastfeeding self-efficacy, self-compassion, and engagement with the infant during feeding all modify or mediate the relationship, and a complex dynamic relationship among cortisol, oxytocin, progesterone, and estrogen is involved. Importantly, recent intervention studies suggest psychosocial interventions may impact both breastfeeding and mood. Providers and researchers should recognize the interrelationship between the breastfeeding and PPD and apply this understanding to patient care through integrated education and care for both mood and breastfeeding enhancement.

Maternal antenatal depression's effects on child developmental delays: Gestational age, postnatal depressive symptoms, and breastfeeding as mediators

BACKGROUND

Maternal antenatal depression experienced around conception or during pregnancy may adversely affect child development. This study explores three potential mechanisms of the effects of antenatal depression on children's developmental delays at 2-3 years: gestational age of the child, continued depressive symptoms postnatally, and interrupted breastfeeding practices.

METHODS

Mothers (N = 2888) of 3450 children, including 2303 singletons and 1147 multiples from the Upstate KIDS cohort provided data. Linked hospital discharge data was combined with mothers' reports to identify women with moderate to severe antenatal depression. Gestational age was extracted from birth certificates. Mothers completed a depression screener at 4 months postpartum, reported about their breastfeeding practices from 4 to 12 months postpartum, and completed a developmental delay screener when children were 24, 30, and 36 months.

RESULTS

In unadjusted path analysis models, mothers with antenatal depression had more postnatal depressive symptoms and breastfed fewer months, which translated into children being more likely to have developmental delays. Gestational age was not a mediator. Effects were similar across girls and boys and singletons and twins, and largely held when adjusting for covariates.

LIMITATIONS

Main limitations were the relatively advantaged sample and reliance on maternal report.

CONCLUSIONS

Maternal antenatal depression may impact child development through continued depressive symptoms in the postpartum period and through reduced breastfeeding duration suggesting additional targets for intervention.

Breastfeeding success in the first 6 months of online breastfeeding counseling after cesarean delivery and its effect on anthropometric measurements of the baby: a randomized controlled study

OBJECTIVE

The aim of this study was to determine the effect of online breastfeeding counseling after cesarean section on breastfeeding success and anthropometric measurements of the baby in the first 6 months.

METHODS

The study was conducted with single-blind randomized controlled experimental research design and performed with 151 primiparous women as intervention (n=76) and control (n=75) groups. The mothers were given training in the first 24 h postpartum by applying the "Data Collection Form," "Breastfeeding and Infant Follow-up Form," and "Breastfeeding Self-Efficacy Scale - Short Form," who followed up at the first and sixth months, and further again for 6 months.

RESULTS

Although there was no difference and homogeneity at the beginning of study among the participants in the intervention group compared with the control group, it was observed that the breastfeeding rates at the first and sixth months were higher and significant. When the anthropometric measurements of the participants in both the groups were compared, it was found that there was a significant difference between the measurements of height and weight at discharge, first, and sixth months. Breastfeeding self-efficacy scores in the intervention group were significantly higher at discharge, 4 weeks postpartum, and 6 months postpartum than those in the control group (p<0.05).

CONCLUSIONS

Breastfeeding training and online counseling given to mothers who give birth by cesarean section during the early postpartum period increased breastfeeding rates and self-sufficiency, and the anthropometric measurements of babies were found to be higher at healthy limits.

Efficacy of behavioral interventions to improve maternal mental health and breastfeeding outcomes: a systematic review

BACKGROUND

Despite extensive benefits and high intentions, few mothers breastfeed exclusively for the recommended duration. Maternal mental health is an important underlying factor associated with barriers and reduced rates of breastfeeding intent, initiation, and continuation. Given evidence of a bidirectional association between maternal mental health and breastfeeding, it is important to consider both factors when examining the efficacy of interventions to improve these outcomes. The purpose of this manuscript is to review the literature on the efficacy of behavioral interventions focused on both maternal mental health and breastfeeding outcomes, examining the intersection of the two.

METHODS

This systematic review was completed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines. Studies were selected if they were available in English, used primary experimental design, and used a behavioral intervention type to examine maternal mental health and breastfeeding outcomes. Articles were identified from PubMed, CINAHL, Embase, and PsycINFO from database inception to 3 March 2022. Study quality was assessed using the Cochrane Risk of Bias tool. Results were synthesized by intervention success for 1. Mental health and breastfeeding, 2. Breastfeeding only, 3. Mental health only, and 4. No intervention effect. PROSPERO CRD42021224228.

RESULTS

Thirty interventions reported in 33 articles were identified, representing 15 countries. Twelve studies reported statistically significant positive effect of the intervention on both maternal mental health and breastfeeding; most showing a decrease in self-report depressive and/or anxiety symptoms in parallel to an increase in breastfeeding duration and/or exclusivity. Common characteristics of successful interventions were a) occurring across pregnancy and postpartum, b) delivered by hospital staff or multidisciplinary teams, c) offered individually, and d) designed to focus on breastfeeding and maternal mental health or on breastfeeding only. Our results are not representative of all countries, persons, experiences, circumstances, or physiological characteristics.

CONCLUSIONS

Interventions that extend the perinatal period and offer individualized support from both professionals and peers who collaborate through a continuum of settings (e.g., health system, home, and community) are most successful in improving both mental health and breastfeeding outcomes. The benefits of improving these outcomes warrant continued development and implementation of such interventions.

Breast Milk and the Importance of Chrononutrition

During pregnancy the human fetus receives timed cues from the circadian rhythms of temperature, metabolites, and hormones from the mother. This influence is interrupted after parturition, the infant does not secrete melatonin and their circadian rhythms are still immature. However, evolution provided the solution to this problem. The newborn can continue receiving the mother's timed cues through breastmilk. Colostrum, transitional, and mature human milk are extraordinary complex biofluids that besides nutrients, contain an array of other non-nutritive components. Upon birth the first milk, colostrum, is rich in bioactive, immunological factors, and in complex oligosaccharides which help the proper establishment of the microbiome in the gut, which is crucial for the infants' health. Hormones, such as glucocorticoids and melatonin, transfer from the mother's plasma to milk, and then the infant is exposed to circadian cues from their mother. Also, milk components of fat, proteins, amino acids, and endogenous cannabinoids, among others, have a markedly different concentration between day and night. In the present review, we give an overview of nutritive and non-nutritive components and their daily rhythms in human milk and explore their physiological importance for the infant. Finally, we highlight some interventions with a circadian approach that emphasize the importance of circadian rhythms in the newborn for their survival, proper growth, and development. It is estimated that ~600,000 deaths/year are due to suboptimal breastfeeding. It is advisable to increase the rate of exclusive breastfeeding, during the day and night, as was established by the evolution of our species.
