The Association of Breastfeeding with a Reduced Risk of Postpartum Depression: A Systematic Review and Meta-Analysis

The moderating impact of personal and collective resilience resources on postpartum depression in conflict-affected environments

BACKGROUND

Women exposed to conflict are at greater risk of experiencing adverse mental health impacts, and women in the postpartum period may face additional distress and heightened risk. Resilience resources, known to mitigate the impacts of stressful events, could offer protection to these new mothers. The current study aimed to assess whether conflict exposure was associated with greater postpartum depression symptoms, and whether three distinct resilience resources - personal resilience, community resilience, and social support - would moderate this association among women highly exposed to an ongoing conflict.

METHODS

This comparative cross-sectional study included 110 women from regions with high conflict exposure near the Israel-Gaza border and 210 women from areas with lower conflict exposure of Israel. Depression symptoms were evaluated six months postpartum, alongside measures of conflict exposure and personal and collective resilience resources. Multiple linear regression analyses tested the hypotheses.

RESULTS

Higher conflict exposure was not associated with increased postpartum depression symptoms. Instead, all resilience resources showed a negative association with depression symptoms. Notably, community resilience significantly moderated the effect of conflict exposure on postpartum depression among highly exposed women, after adjusting for personal characteristics.

LIMITATIONS

The study's cross-sectional design and reliance on online data collection may have introduced a selection bias.

CONCLUSIONS

These findings underscore the critical protective role of community resilience for new mothers in conflict-laden regions. They indicate the importance of mental health interventions that bolster not just individual resilience but also community support, and suggest a shift toward more integrative, community-focused approaches in addressing mental health challenges in such settings.

Prevalence of cognitive dysfunction and associated behavioral changes, lactational failure, and their determinants among postpartum women in South India: A community-based study

OBJECTIVES

To estimate the prevalence of cognitive dysfunction and associated behavioral changes and their prevalence among postpartum women, and also the prevalence of lactational failure and its determinants among postpartum women.

METHODS

A cross-sectional study was conducted involving 200 postpartum women (65% rural, 35% urban). Data were collected through structured interviews and assessments using the Indian version of the Montreal Cognitive Assessment and Depression, Anxiety, and Stress Scale-21. Statistical analyses included chi-square tests and regression models.

RESULTS

Cognitive dysfunction was observed in 25% of participants (21.5% mild, 3.5% moderate). Stress, anxiety, and depression were prevalent in 80.5%, 27%, and 30% of women, respectively. Lactational failure was reported by 21%, strongly correlated with cognitive dysfunction (P = 0.01) and mental health issues (stress, anxiety, and depression; P < 0.001). Key determinants of lactational failure included poor mother-partner relationships, lack of social support, low education levels, delayed breastfeeding initiation, childcare stress, comorbidities, mode of delivery, and low birth weight. Cognitive dysfunction was significantly associated with male offspring, insufficient milk production, lack of social support, and poor education levels (P < 0.001).

CONCLUSION

The study highlights a strong association between maternal mental health, cognitive dysfunction, and lactational failure. Addressing psychosocial and demographic determinants through targeted interventions is critical for improving maternal and child health outcomes in postpartum populations.

Adaptive and maladaptive profiles in mothers of infants - a cross-sectional study on the meaning of self-confidence and mental health

AIM

The main goal of this study is to identify profiles of mothers based on the level of maternal self-confidence, and symptoms of depression and anxiety. Moreover, the objective is to evaluate how these profiles differ regarding perinatal, parental, and health variables.

METHODS

A prospective study was performed from 2020 to 2021 with 179 postpartum mothers of infants who had participated in a longitudinal study (The Cope Study) during pregnancy. The survey included sociodemographic, prenatal, parental, and health details and standardized psychological measures: MCQ, PHQ-2, and GAD-7.

FINDINGS

The cluster analyses revealed two profiles of mothers. The first was described as the "adaptive profile of mothers," with high self-confidence and low rates of depression and anxiety (60, 3 %), and the second was defined as the "maladaptive profile of mothers," with low maternal self-confidence and high rates of depression and anxiety (39.7 %). In the "maladaptive profile of mothers" group, more women experienced higher stress, declared fewer health-promoting behaviors, assessed their health as worse, received less support from their families, had labor induction, and had low birth satisfaction.

CONCLUSION

These results support the importance of early and multilevel psychological screening to understand the experience of infants' mothers and to develop targeted and increasingly personalized interventions.

Good practice in lactation counseling for Ukrainian refugee mothers to ensure the health and mental benefits of breastfeeding - an observational study

PURPOSE

The study presents a cross-sectional analysis of the population of Ukrainian women who received maternity care in 11 Polish hospitals.

METHODS

Multidirectional lactation counseling was implemented from March to November 2023 by the Human Milk Bank Foundation in cooperation with UNICEF Refugee Response Office in Poland. Medical data were collected using questionnaires prepared for the study. When the mother indicated that she had mental problems or the health care personnel spotted problems, she was she referred to a psychologist for diagnostics, who used questionnaires appropriate to the patient's situation such as: Patient Health Questionnaire-9 for depression assessment and Generalized Anxiety Disorder Questionnaire-7 for anxiety assessment.

RESULTS

In total, 1203 consultations were carried out, of which 542 were lactation counseling, 305 - were physiotherapy, 227 - were psychological, and 129 - were with speech-language pathologists. Two hours of skin-to-skin contact (SSC) and latching on the breast within the 1st hour postpartum occurred in more than half of the participants. In the rest of the population, shortened or lack of SSC was associated with breastfeeding delayed by at least one day. 53% of the population required lactation counseling, of which 242 were one-time visits. Continued support was 98% effective in achieving breastfeeding goals. 167 mothers required psychological support, of which only 53 women continued treatment beyond one-time counseling. Only about 1% of women experienced mental disorders based on a psychological interview.

CONCLUSION

The use of lactation counseling more often than psychological counseling by refugee mothers could be related to the beneficial effects of breastfeeding on maternal well-being through hormonal self-regulation and empowerment as a mother. However, focused research is needed on the impact of breastfeeding on the mental health of refugee women.

The role of breastfeeding self-efficacy in the relationship between perinatal depressive symptoms and exclusive breastfeeding: a longitudinal mediation analysis

BACKGROUND

Perinatal depressive symptoms are associated with exclusive breastfeeding; however, the longitudinal mediating process of this relationship remains unclear. Breastfeeding self-efficacy may be an important variable in understanding the complex process involved in their co-occurrence. Therefore, we aimed to explore the role of breastfeeding self-efficacy in the relationship between perinatal depressive symptoms and exclusive breastfeeding using both between- and within-person approaches.

METHODS

A prospective longitudinal study was conducted from October 2021 to January 2024 at a tertiary hospital in Hunan, China. Depressive symptoms were measured at 36 gestational weeks and 1 week, 6 weeks, 3 months, and 6 months postpartum. Exclusive breastfeeding and breastfeeding self-efficacy were evaluated at the same postpartum intervals. Cross-lagged panel models, random intercepts cross-lagged panel models, and longitudinal mediation models were used to analyze their relationships.

RESULTS

A total of 334 participants were included. Longitudinal mediation models revealed that breastfeeding self-efficacy mediated the prospective negative effect of perinatal depressive symptoms on exclusive breastfeeding at the between-person level (b = - 0.017, SE = 0.008, 95% CI (- 0.032, - 0.001), P = 0.036), and suppressed the positive effect of exclusive breastfeeding on depressive symptoms at the within-person level (b = - 0.044, SE = 0.022, 95% CI (- 0.087, 0.000), P = 0.047).

CONCLUSIONS

Mothers with perinatal depressive symptoms may face challenges in exclusive breastfeeding due to reduced breastfeeding self-efficacy. While increasing exclusive breastfeeding might help reduce depressive symptoms over time, this positive effect can be hindered if breastfeeding self-efficacy remains low. Our findings highlight breastfeeding self-efficacy as a critical target for future interventions.

Feeding Patterns and Postpartum Depressive Symptoms: The Mediating Role of Parenting Self-Efficacy

Objective: The mechanisms underlying the association between breastfeeding and postpartum depressive symptoms remain unclear. In this study, we analyzed the relationship between maternal feeding patterns and postpartum depressive symptoms and investigated the mediating role of parenting self-efficacy (PSE). Methods: A prospective longitudinal survey of 708 mothers was conducted from September 2018 to August 2020. Structural equation modeling was used to examine the relationship between feeding patterns and postpartum depressive symptoms and the effect of PSE. Results: Breastfeeding mothers experienced milder depressive symptoms and higher PSE than women who did not breastfeed. The structural equation modeling results showed a direct effect of feeding patterns on postpartum depressive symptoms and an indirect effect of postpartum depressive symptoms through PSE. Conclusions: Feeding patterns affected postpartum depression through PSE, which enhanced the favorable effects of breastfeeding in preventing postpartum depression and protecting maternal mental health. Future measures aimed at optimizing PSE will not only help prevent postpartum depression but also contribute to further promoting the psychological health and resilience of breastfeeding women.

Breastfeeding interventions for preventing postpartum depression

BACKGROUND

Postpartum depression is a debilitating mental health disorder, which occurs in approximately 6% to 13% of women who give birth in high-income countries. It is a cause of great suffering for women and can have long-term consequences for child development. Postpartum depression can also negatively influence breastfeeding duration and breastfeeding exclusivity (i.e. feeding the infant only breast milk). However, a positive early, and continued, breastfeeding experience may reduce the risk of having postpartum depression. Breastfeeding interventions that increase the duration and exclusivity of breastfeeding may help prevent or reduce postpartum depressive symptoms.

OBJECTIVES

The primary objective of this review was to assess the effect (benefits and harms) of breastfeeding support interventions, in comparison to standard perinatal care, on maternal postpartum depression. The secondary objective was to assess whether breastfeeding support interventions had an effect on depression symptoms, and whether the effect was dependent on the duration and exclusivity of breastfeeding.

SEARCH METHODS

We searched CENTRAL (Wiley), MEDLINE ALL (Ovid), Embase (Ovid), PsycINFO (Ovid), CINAHL Complete (Ebsco) and several other bibliographic databases and trial registers. The most recent search was conducted in June 2024.

SELECTION CRITERIA

Randomised controlled trials (RCTs) that evaluated educational, psychosocial, pharmacological, alternative (any breastfeeding support intervention that promotes relaxation and reduces stress) or herbal breastfeeding support interventions targeting the prevention or reduction of postpartum depression were eligible for inclusion.

DATA COLLECTION AND ANALYSIS

Each title and abstract we identified was screened by two authors independently. Two review authors then independently examined full-text manuscripts to decide if the study met the inclusion criteria. If so, they extracted data from included studies using Covidence software. Two review authors also independently conducted a risk of bias assessment of each study using the RoB 2 tool. We contacted study authors when necessary for more information. We conducted meta-analyses using a random-effects model.

MAIN RESULTS

We included 10 RCTs with 1573 participants in this review. Depression was measured using the Edinburgh Postnatal Depression Scale (EPDS) in all studies, where scores range between 0 and 30 (higher scores indicating more depressive symptoms). The studies used a score of over 10 as the cut-off for a diagnosis of depression. Primary outcome It is very uncertain whether psychosocial breastfeeding interventions had any effect on the incidence of postpartum depression immediately post-intervention (RR 0.78, 95% CI 0.23 to 2.70; 1 study, 30 participants), but we found low-certainty evidence that psychosocial breastfeeding interventions may prevent the incidence of postpartum depression in the short term (one to three months) post-intervention (risk ratio (RR) 0.37, 95% confidence interval (CI) 0.14 to 0.93; 1 study, 82 participants). It is very uncertain whether alternative breastfeeding interventions had any effect in preventing the incidence of postpartum depression immediately post-intervention (RR 0.64, 95% CI 0.27 to 1.54; 1 study, 60 participants). The short-term time point was not measured. Secondary outcomes It is very uncertain whether psychosocial breastfeeding interventions had any effect on reducing depressive symptoms immediately post-intervention (mean difference (MD) -0.67, 95% CI -1.63 to 0.28; 4 studies, 512 participants). There is very low-certainty evidence that psychosocial breastfeeding interventions could reduce symptoms of anxiety immediately post-intervention as measured with the Zung Self-rating Anxiety Scale (SAS), where scores between 45 and 59 out of 80 on the SAS indicate mild to moderate anxiety, scores between 60 and 74 marked severe anxiety levels and > 75 extreme anxiety levels (MD -2.30, 95% CI -4.36 to -0.24; 1 study, 100 participants). There was no difference in rates of exclusive breastfeeding immediately post-intervention between those offered a psychosocial breastfeeding intervention and those receiving standard care, but the evidence is very uncertain (RR 1.20, 95% CI 0.96 to 1.51; I2 = 29%; 571 participants; very low-certainty evidence). We found low-certainty evidence that a psychosocial breastfeeding intervention may increase the duration of breastfeeding in the long term (RR 1.64, 95% CI 1.08 to 2.50; 129 participants; low-certainty evidence). For the comparison of alternative breastfeeding intervention versus standard care (which was evaluated in only one study), there was no difference between groups immediately post-intervention in anxiety measured with the State-Trait Anxiety Inventory (STAI); range 20 to 80; higher scores indicate more severe anxiety symptoms (MD 1.80, 95% CI -9.41 to 13.01; 60 participants; very low-certainty evidence), or in stress measured with the Perceived Stress Scale (PSS)-NICE; range 1 to 230, higher scores indicate higher levels of stress (MD 1.90, 95% CI -10.28 to 14.08; 60 participants; very low-certainty evidence), but the evidence is very uncertain. No adverse events connected to the intervention itself were stated in any of the trials, but for most studies, we do not know if this is because there were none or because they were not measured or reported.

AUTHORS' CONCLUSIONS

There is low-certainty evidence that psychosocial breastfeeding interventions may prevent postpartum depression in the short term and increase the duration of breastfeeding in the long-term. The evidence is very uncertain about the effect of psychosocial breastfeeding interventions on other outcomes. The evidence is very uncertain about the effect of alternative breastfeeding interventions on postpartum depression or other outcomes. The included studies did not report any adverse events directly related to the interventions, but it is not clear if this outcome was measured in most studies. Future trials of breastfeeding interventions should be conducted carefully to reduce their risk of bias, and they should be large enough to detect differences between mothers in their mental health.

Engaging Family Members to Support Exclusive Breastfeeding, Responsive care, and Antiretroviral Therapy Adherence Among Families with Children who are HIV-Exposed and Uninfected

Children who are HIV-exposed and uninfected (CHEU) are at increased risk for poor growth, health, and development compared to children who are HIV-unexposed and uninfected. To support families with CHEU, we assessed the acceptability of engaging family members to support women living with HIV (WLWH) with exclusive breastfeeding (EBF) and antiretroviral therapy (ART) adherence and to engage in responsive infant caregiving. We conducted trials of improved practices, a consultative research approach, that follows participants over time as they try recommended behaviors. We enrolled postpartum women in Lusaka, Zambia, who identified home supporters. At visit 1, WLWH were interviewed about current practices. At visit 2, WLWH and home supporters received tailored EBF, responsive care, and ART adherence counseling. At visit 3, WLWH and home supporters were interviewed about their experiences trying recommended practices for 2-3 weeks. Interview transcripts were analyzed thematically. Participants included 23 WLWH, 15 male partners, and 8 female family members. WLWH reported several barriers to EBF. The most common were fear of HIV transmission via breastfeeding-despite high ART adherence-and insufficient breastmilk. After counseling, WLWH reported less fear of HIV transmission and improved breastfeeding practices. Home supporters reported providing WLWH increased support for EBF and ART adherence and practicing responsive caregiving. Both male and female home supporters appreciated being included in counseling and more involved in caregiving, and WLWH valued the increased support. Families with CHEU need focused support. Tailored counseling and family support for WLWH show promise for improving EBF, responsive caregiving, and ART adherence.

Neuropsychological complications of hypoprolactinemia

Prolactin (PRL) is primarily produced by the pituitary lactotrophic cells and while initially named for its role in lactation, PRL has several other biological roles including immunomodulation, osmotic balance, angiogenesis, calcium metabolism, and appetite regulation. Most of the PRL-related literature has traditionally focused on hyperprolactinemia, whereas hypoprolactinemia has received little attention. There is evidence to suggest that PRL receptors are widely distributed within the central nervous system including the limbic system. Furthermore, PRL has been shown to play key role in the stress regulation pathway. Recent data also suggest that hypoprolactinemia may be associated with increased sexual dysfunction, anxiety, and depression. In this paper we discuss the current understanding regarding the neuropsychological impact of hypoprolactinemia and highlight the need for adequately defining hypoprolactinemia as an entity and consideration for future replacement therapies.

Receiving screened donor human milk as part of a community-based lactation support programme reduces parental symptoms of anxiety and depression

Infant feeding decisions and maternal mental health are closely tied. Donor human milk (DHM) protects premature infant health and development and can reduce hospital stays. Recent qualitative research has highlighted that having the option for an infant to receive DHM can also support parental wellbeing through reducing concerns about infant health and supporting feeding preferences. However, no quantitative study has examined this relationship. In this study, anxiety and depression scores were measured before and after receiving DHM using the Hospital Anxiety and Depression Scale for 80 parents (77 mothers, 3 fathers) who had sought DHM from a community-facing milk bank. Reasons for seeking DHM included maternal cancer, maternal and infant health complications, insufficient glandular tissue, and low milk supply. Open-ended questions explored the experience of receiving milk. Milk bank records were used to match details of milk given (volume, duration, exclusivity, lactation support given) with survey responses. Both anxiety and depression scores significantly reduced after receiving milk. Although greater lactation support and longer duration of milk predicted a greater decrease in scores, in a regression analysis, only volume of milk given remained a significant predictor. Almost all parents agreed that being able to access DHM supported their wellbeing predominantly through reducing anxieties around infant health but also through feeding choices being respected and the support given at difficult times. The findings add important considerations to the literature considering when and for whom DHM should be used and the complex interplay between infant feeding and mental health.

'It's far from the norm': breastfeeding beyond 1 year in the Republic of Ireland

Breastfeeding is the optimal form of nutrition for infants and young children. The World Health Organization recommends that babies are breastfed exclusively for the first 6 months of life, and up to the age of 2 years or beyond in combination with complementary food. Breastfeeding initiation and continuation rates are suboptimal globally and very low in the Republic of Ireland where health promotion initiatives and healthcare professional support predominantly focus on the important phase of initiation and early months of the breastfeeding journey. This qualitative descriptive study aimed to explore the experiences of women who chose to breastfeed their children beyond 1 year of age in the Republic of Ireland. Fourteen women participated in semi-structured interviews. Interviews were transcribed verbatim and thematic analysis was conducted. The analysis generated three overarching themes: (1) Influences on breastfeeding beyond 1 year, (2) Sustaining breastfeeding and (3) Benefits of breastfeeding beyond 1 year. Family, friends, peers, culture and commercial milk formula marketing had an influence on breastfeeding journeys. Support, determination, knowledge, bed-sharing and Covid-19 pandemic social restrictions helped to sustain breastfeeding beyond 1 year. Benefits of breastfeeding beyond 1 year such as nutrition, strengthening of emotional bonds, development of a parenting tool, and protection of child and maternal health were identified. Our findings support the need for discussions and further research on the normalization of breastfeeding beyond 1 year in the Republic of Ireland, targeted health promotion initiatives and education programmes for healthcare professionals on supporting the continuation of breastfeeding.

From Breastfeeding to Support in Mothers' Feeding Choices: A Key Role in the Prevention of Postpartum Depression?

The postpartum period represents a critical phase of profound transition for women. This timeframe encompasses the physical recuperation associated with childbirth, the intricate psychosocial adjustments inherent in assuming the role of motherhood and also important alterations in steroid and peptide hormones. Hence, as women navigate the reconfiguration of relationships and strive to address the diverse needs of their infants and family members, they concurrently grapple with dramatic transformations which are characteristic of the postpartum phase. In fact, relevant prevalence ranges are reported for maternity blues, a mild condition characterized by self-limited and transient depressive symptoms, but also a well-established risk factor for more serious postpartum mood disorders, such as depression (PPD), with an incidence of 10-15%. Unlike in the US, at the European level, there are no concrete recommendations for the routine integration of the assessment of the mother's emotional state by healthcare professionals, with a considerable risk of underdiagnosing or undertreating these conditions. In this regard, there is a growing body of scientific evidence on the important role of breastfeeding in reducing the risk of PPD and also of the importance of mothers' compliance with this practice. Indeed, sucking the baby regulates the circadian rhythm of the HPA axis and, together with the action of prolactin, the stress response is decreased. In addition, other positive consequences of breastfeeding, which are inversely correlated with the onset of PPD, include the regulation of sleep and waking patterns for mother and baby, the improvement of the mother's self-efficacy and her emotional involvement. It should also be considered that the request for support for breastfeeding can often conceal a request for support for motherhood itself and for the mother's emotional well-being. It therefore emerges that the personnel involved in primary pediatric care to provide adequate support in the transition to motherhood must support mothers in their breastfeeding choices, whether breastfeeding or formula feeding, so that each choice is made conscientiously and serenely. Therefore, neonatal feeding assumes a decisive role, since if, on the one hand, it regulates specific neurohormonal pathways that are protective for maternal emotional well-being (breastfeeding), on the other hand, support in mothers' breastfeeding choices, even in the case of formula feeding, means validating their being mothers in the absence of judgement and counteracting any feelings of inadequacy, conditions that are inversely correlated to DPP.

A Longitudinal Qualitative Study of Barriers and Facilitators of Breastfeeding in Women on Opioid Maintenance Therapy

PURPOSE

To understand how barriers and facilitators interact over time to support or disrupt breastfeeding among women on opioid maintenance therapy for opioid use disorder.

BACKGROUND

Breastfeeding has additional benefits for newborns with prenatal opioid exposure. Up to 80% of women on opioid maintenance therapy plan to breastfeed, but many do not beyond the first 7 to 10 days.

METHODS

A qualitative, longitudinal design was used. Semi-structured interviews occurred during the third trimester of pregnancy and again between 1 and 6 weeks postpartum. Thematic analysis was conducted using the Breastfeeding in a Life Course Context model as a framework. The design and methods were informed by a post-positivist, critical realist perspective.

RESULTS

Thirteen participants were enrolled, and 19 interviews were completed. Five themes were identified. It Will Work Out was the primary theme that describes participants' sense of self-efficacy, stemming from their experiences of managing addiction recovery. Women considered breastfeeding to support their own health and that of their newborn while in recovery, summarized by Being Healthy. Making the choice to breastfeed, represented by Weighing the Options, was influenced by their perinatal health care providers. During the Sensitive Period, challenges could overwhelm their self-efficacy. Of 9 women, 4 were still breastfeeding when interviewed postpartum, exemplified by Moving On.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Participants' self-efficacy and motivation to be healthy played a significant role in managing breastfeeding challenges over time. Nursing interventions must empower women's self-efficacy to help them achieve their breastfeeding goals.

A systematic review of the benefits of breastfeeding against postpartum depression in low-middle-income countries

BACKGROUND

The positive impact of breastfeeding against postpartum depression has been increasingly reported. However, no studies have systematically and critically examined current evidence on breastfeeding practices' influences on postpartum depression in LMICs.

AIM

To review the influence of breastfeeding on postpartum depression in LMICs.

METHODS

We searched original research in English published over the last ten years (2012 - 2022) within 8 databases: EBSCOhost, EMBASE, Pubmed, Sage Journals, Science Direct, APA PsycArticles, Taylor & Francis, Google Scholar, and citation tracking. The risk of bias assessment used The Newcastle Ottawa Scale and The Modified Jadad Scale. We followed the PRISMA statement after the protocol had been registered on the PROSPERO. The review included 21 of 11015 articles.

RESULTS

Of 21 articles, 16 examined breastfeeding practices, 2 each investigated breastfeeding self-efficacy and breastfeeding education, and 1 each assessed breastfeeding attitude and breastfeeding support. 3 randomized control trials and 5 cohorts revealed that breastfeeding decreased the EPDS scores. However, 4 cross-sectional studies indicated that breastfeeding is nonsignificantly associated with postpartum depression.

CONCLUSION

This review indicated that breastfeeding may alleviate or prevent postpartum depression. Our findings indicated that integrating breastfeeding-related programs and policies into postpartum depression prevention may benefit public health.

REGISTRATION

PROSPERO (CRD42022315143).

Weaning and depression: a closer look

The association of weaning with depression has long been recognized. However, interest in the study of post-weaning depression has waned over the last few decades partly due to changes in the nosology of perinatal psychiatric disorders. In this paper, we review the relevant literature and conclude that post-weaning depression is a rare but severe complication of breastfeeding cessation. Given that post-weaning depression is an understudied and often undiagnosed clinical condition, research is needed to address this important unmet need.

The role of breastfeeding and formula feeding regarding depressive symptoms and an impaired mother child bonding

Associations between depressive symptoms and breastfeeding are well documented. However, evidence is lacking for subdivisions of feeding styles, namely exclusive breastfeeding, exclusive formula feeding and a mixed feeding style (breastfeeding and formula feeding). In addition, studies examining associations between mother-child-bonding and breastfeeding have yielded mixed results. The aim of this study is to provide a more profound understanding of the different feeding styles and their associations with maternal mental health and mother-child-bonding. Data from 307 women were collected longitudinally in person (prenatally) and by telephone (3 months postnatally) using validated self-report measures, and analyzed using correlational analyses, unpaired group comparisons and regression analyses. Our results from a multinomial regression analysis revealed that impaired mother-child-bonding was positively associated with mixed feeding style (p = .003) and depressive symptoms prenatal were positively associated with exclusive formula feeding (p = .013). Further studies could investigate whether information about the underlying reasons we found for mixed feeding, such as insufficient weight gain of the child or the feeling that the child is unsatiated, could help prevent impaired mother-child-bonding. Overall, the results of this study have promising new implications for research and practice, regarding at-risk populations and implications for preventive measures regarding postpartum depression and an impaired mother-child-bonding.

Awareness of the Maternal Health Benefits of Lactation Among U.S. Pregnant Individuals

INTRODUCTION

We assessed awareness of the maternal health benefits of lactation among a sample of nulliparous pregnant individuals in the United States, identified variables associated with awareness of these benefits, and examined whether awareness of these benefits impacts breastfeeding attitudes or intentions.

METHODS

We administered a web-based survey to nulliparous U.S.-born individuals carrying a singleton gestation of at least 28 weeks. We assessed awareness of the maternal health benefits of lactation using 10 items to create a summative score. We examined variation in awareness of these benefits by demographic characteristics, health insurance, and personal or family health history and used multivariable models to estimate associations between awareness of the maternal health benefits of lactation and breastfeeding intentions.

RESULTS

Of the 675 individuals invited to complete surveys, 451 (67%) responded. Only 50% were aware that breastfeeding lowers maternal risk of breast cancer; fewer were aware that breastfeeding lowers the risk of ovarian cancer (35%), diabetes (27%), and hypertension and heart disease (26%). Awareness of the maternal benefits of lactation did not vary by age or race/ethnicity. However, significant regional variation was noted. In multivariable models, scores of awareness of the maternal health benefits of breastfeeding were significantly associated with intentions to breastfeed for at least 12 months (adjusted odds ratio, 1.23; 95% confidence interval, 1.11, 1.37).

CONCLUSIONS

Efforts to increase awareness of the maternal health benefits of lactation are still needed. Increasing awareness of the maternal health benefits of lactation may strengthen intentions to breastfeed as recommended.

Postpartum depression and its relationship with the positive and negative perfectionism

BACKGROUND

Depression is a common mental disorder after childbirth, which has serious consequences for the mother, baby, and family. A wide range of causes, including some personality traits of mothers, are involved in its etiology. Therefore, this study was conducted aiming to determine the factors related to postpartum depression (PPD) and its relationship with positive and negative perfectionism in Qom, Iran.

MATERIALS AND METHODS

This cross-sectional analytical study was conducted on 162 mothers who had been referred to health centers in Qom during 6-8 weeks after normal vaginal delivery (NVD) in 2020. After randomly classifying the health centers, the convenience sampling method was carried out. Data collection tools included social-individual information form, Edinburg Postnatal Depression Scale (EPDS), and Positive and Negative Perfectionism Questionnaire of Terry-Short. The data were analyzed using the Chi-square and Pearson correlation tests and multivariate logistic regression analysis.

RESULT

The prevalence of PPD in this study was 29.6%. The results showed that with the increase in the negative dimension of perfectionism, the chance of PPD in people increases by 14% (OR = 1.14, CI = 1.06-1.21), while there was no significant correlation between the positive dimension of perfectionism and PPD (r = 0.006, P > 0.05). Furthermore, the chance of PPD was higher in student mothers, mothers who had a history of PPD, and unintended pregnancy. Moreover, some factors such as multigravidity, breastfeeding, and not worrying about body image reduce the chance of occurrence.

CONCLUSION

Since mothers' negative perfectionism is associated with PPD, it is recommended to identify perfectionist individuals during pregnancy and after delivery and provide counseling service to them.

Factors associated with informal human milk sharing among donors and recipients: A mixed-methods systematic review

BACKGROUND

The multiple benefits associated with the provision of human milk exceed individual health outcomes, engendering substantial economic, societal and environmental domains. Human milk is the absolute, unparalleled source of nutrition for infants. Informal human milk sharing is a modernistic and rapidly progressing practice. No systematic review of the factors associated with this contemporary practice among donors and recipients of informal human milk sharing exists.

AIM

The aim of this review was to identify, evaluate, synthesize and integrate the evidence on the factors associated with informal human milk sharing among donors and recipients.

METHODS

A mixed methods systematic review was conducted according to the Joanna Briggs Institute methodological guidance utilizing a convergent integrated approach. The following databases were systematically searched: CINAHL, Scopus, Medline and Embase and Web of Science between inception to August 2023. A grey literature search was conducted using multiple techniques. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

RESULTS

Twenty-four studies were included in this review. Ten integrated findings relating to the factors associated with informal human milk sharing among donors and recipients were identified. The four integrated findings pertaining to donors included: altruistic motivation and value, resistance to commercialization and overcoming inaccessibility, uniting digital and personal connectedness and lack of awareness and acceptance of informal human milk sharing in healthcare settings. The six integrated findings relating to recipients included: maternal or infant factors, superiority and advantageous impact of breastmilk, human milk bank influences, digital connections and transparency, healthcare professional facilitation of informal human milk sharing, and professional and logistical implications.

CONCLUSION

This review highlighted a multitude of factors that motivate, facilitate and impede the practice of informal human milk sharing. Future research is required to explore these factors further within broader geographical locations to enhance the generalizability and rigor of the body of knowledge. Further studies should consider the exploration of the experiences and psychological impact of informal human milk sharing on donors and recipients. The provision of human milk to all infants is an imperative public health endeavor and thus positioning this as a key benchmark for research and practice is crucial.

Association between breastfeeding cessation among under six-month-old infants and postpartum depressive symptoms in Nevada

BACKGROUND

Postpartum depression affects 13% of women after childbirth in the United States. Mothers who experience depression are less likely to breastfeed than those who do not experience depression. On the other hand, breastfeeding may have a positive effect on maternal mental health.

RESEARCH AIM

We aimed to analyze whether breastfeeding cessation is associated with postpartum depression symptoms among mothers of infants under six months old in Clark County, Nevada.

METHOD

A cross-sectional study was conducted in 2021 using a purposive sample of 305 mother-infant dyads. Postpartum depression symptoms were assessed using the Patient Health Questionnaire-2 (PHQ-2), and the breastfeeding cessation was determined through a 24-hour dietary recall. Descriptive, bivariate, and multivariate logistic regression analyses were conducted.

RESULTS

Most participants were between 25 and 34 years old (n = 183, 60.0%), multiparous (n = 167, 55.1%), and had a vaginal delivery (n = 204, 70.6%). High frequency of postpartum depressive symptoms was found among mothers who were young (18-24 years) (24.2%), without a partner (25.0%), had unplanned pregnancies (12.7%), and were primiparous (13.2%). Breastfeeding cessation was independently associated with postpartum depressive symptoms (AOR = 3.30, 95% CI: 1.16-9.32) after controlling for sociodemographic, environmental, and obstetric characteristics.

CONCLUSION

Breastfeeding cessation is strongly associated with postpartum depressive symptoms among mother-infant dyads in Nevada. Early identification of postpartum depressive symptoms and the promotion of breastfeeding can create a positive feedback loop to foster the well-being of mothers and infants.

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.

Randomized controlled trial to prevent postpartum depressive symptomatology: An infant carrier intervention

BACKGROUND

There is a need for effective interventions to reduce symptomatology of postpartum depression. The objective of this study was to test whether providing an ergonomic infant carrier would reduce postpartum depression symptomatology.

METHODS

A randomized two-arm, parallel-group trial with 100 participants was conducted between February 2018 and June 2019 in a low-income community. At 30-weeks' gestation, 50 participants were randomly assigned to receive an ergonomic infant carrier and instructions on proper use (intervention group), and 50 participants were assigned to a waitlist (control group). Participants tracked the extent of their infant carrier use and completed the Edinburgh Postpartum Depression Scale (EPDS) to assess postpartum depression symptomatology at 6-weeks postpartum.

RESULTS

Participants in the intervention group reported using an infant carrier significantly more often than the control group (β = 2.69, SE = 0.347, p < .001, 95 % CI = 2.08-3.41). The intervention group reported fewer depressive symptoms at 6-weeks postpartum than the control group (β = -0.541, p = .042).

LIMITATIONS

The sample size was relatively small and thus our results may not be generalizable to the general population.

CONCLUSION

Infant carrying may be a cost-effective intervention to reduce postpartum depression symptomatology. Large-scale studies are warranted to further examine the efficacy and cost-effectiveness of providing carriers as an intervention to reduce postpartum depression symptomatology.

Association of breastfeeding with mental disorders in mother and child: a systematic review and meta-analysis

BACKGROUND

Breastfeeding has long been associated with numerous benefits for both mothers and infants. While some observational studies have explored the relationship between breastfeeding and mental health outcomes in mothers and children, a systematic review of the available evidence is lacking. The purpose of this study is to systematically evaluate the association between breastfeeding and mental health disorders in mothers and children.

METHODS

We systematically searched MEDLINE and EMBASE from inception to June 2, 2023. The inclusion criteria consisted of all studies evaluating links between breastfeeding and development of mental health disorders in children and mothers. Risk of bias was assessed using the Newcastle-Ottawa Scale (NOS) while grading of Recommendations Assessment, Development and Evaluation (GRADE) was used to assess the certainty of evidence. A random-effects meta-analysis was used if possible, to estimate the odds ratio for the association between breastfeeding and mental health outcomes. The Mantel-Haenszel method was utilised for pooling ORs across studies. Study heterogeneity was assessed using the I2 statistic.

RESULTS

Our review identified twenty-one original study. Of these, 18 focused on the association between breastfeeding and child health, assessing depressive disorders, schizophrenia, anxiety disorders, eating disorders and borderline personality disorder. Three studies evaluated the associations between breastfeeding and maternal mental health disorders. Three studies looking at outcomes in children showed no significant association between breastfeeding and occurrence of schizophrenia later in life (OR 0.98; 95% CI 0.57-1.71; I2 = 29%). For depressive disorders (5 studies) and anxiety disorders (3 studies), we found conflicting evidence with some studies showing a small protective effect while others found no effect. The GRADE certainty for all these findings was very low due to multiple limitations. Three studies looking at association between breastfeeding and maternal mental health, were too heterogeneous to draw any firm conclusions.

CONCLUSIONS

We found limited evidence to support a protective association between breastfeeding and the development of mental health disorders in children later in life. The data regarding the association between breastfeeding and maternal mental health beyond the postnatal period is also limited. The methodological limitations of the published literature prevent definitive conclusions, and further research is needed to better understand the relationship between breastfeeding and mental health in mothers and children.

Postpartum depression screening in mothers and fathers at well-child visits: a feasibility study within the NASCITA cohort

OBJECTIVE

To assess the feasibility of the family paediatrician's (FP) role in identifying the signs of postpartum depression in parents in time to guarantee child well-being.

DESIGN, SETTING AND PARTICIPANTS

Data for this observational prospective study were collected within the NASCITA (NAscere e creSCere in ITAlia) cohort. During the first visit, paediatricians collected sociodemographic data regarding the parents and information about their health status, the pregnancy and the delivery. Whooley questions were administered during the first and second visits (scheduled 60-90 days after childbirth). Moreover, on the third visit (5-7 months after childbirth) the FP was asked to answer 'yes' or 'no' to a question on the parental postpartum depression, based on his knowledge and on the acquired information.

RESULTS

In 2203 couples who completed the assessment, 529 mothers (19.9%), 141 fathers (6.3%) and 110 (5%) couples reported any depressive symptomatology. Of these, 141 mothers (5.3% of the total sample) and 18 fathers (0.8% of the total sample) were classified as 'likely depressed'. An association was found between maternal postnatal depressive symptoms and having a diagnosed psychiatric disorder during pregnancy (OR 9.49, 95% CI: 3.20 to 28.17), not exclusively breastfeeding at hospital discharge (OR 1.76, 95% CI: 1.19 to 2.61) and the presence of child sleeping disorders at 3 (OR 2.46, 95% CI: 1.41 to 4.28) and 6 months (OR 2.18, 95% CI: 1.37 to 3.47). Another significant predictor of postpartum depression was being primiparous (OR 1.99, 95% CI: 1.31 to 3.02). Concerning the fathers, a significant association was reported only between likely depressed fathers and child sleeping disorders at 3 months (OR 7.64, 95% CI: 2.92 to 19.97). Moreover, having a likely depressed partner was strongly associated with depressive symptoms in fathers (OR 85.53, 95% CI 26.83 to 272.69).

CONCLUSIONS

The findings of this study support the feasibility of an active screening programme for parental postnatal depression during well-child visits as an integral part of postpartum care.

Breastfeeding at Any Cost? Adverse Effects of Breastfeeding Pain on Mother-Infant Behavior

Breast milk is considered the ideal infant nutrition, and medical organizations encourage breastfeeding worldwide. Moreover, breastfeeding is often perceived as a natural and spontaneous socio-biological process and one of the fundamental roles of new mothers. While breastfeeding is beneficial, little scientific consideration has been given to its potential psychological challenges. Here, we investigate the phenomenon of breastfeeding pain in mothers and its association with maternal and infant behavioral regulation. During the postpartum weeks, the mother-infant dyad can be considered one allostatic unit directed at infant regulation and development. We hypothesize that pain comprises an allostatic challenge for mothers and will thus impair the capacity for dyadic regulation. To test this, we recruited 71 mothers with varying levels of breastfeeding pain and videotaped them with their infants (2-35 weeks old) during spontaneous face-to-face interactions. We quantified the individual differences in dyadic regulation by behaviorally coding the second-by-second affective expressions for each mother and infant throughout their interactions. We tested the extent to which breastfeeding pain alters affect regulation during mother-infant interactions. We discovered that mothers with severe breastfeeding pain express less affective expressions and less infant-directed gaze during interactive moments of engagement and play than mothers with no or moderate pain. Moreover, infants of mothers experiencing pain during breastfeeding express less affective expressions and more mother-directed gaze while interacting with their mothers than infants of mothers who are not in pain. This demonstrates that the allostatic challenge of maternal pain interferes with the behavioral regulation of both mothers and infants. Since the mother-infant dyad is a codependent allostatic unit, the allostatic challenges of one partner can impact the dyad and thus potentially impact child development, bonding, and mother and infant well-being. The challenges of breastfeeding should be considered in addition to the nutritional advances.

Factors associated with postpartum depression symptoms among postpartum women in five countries during the COVID-19 pandemic: an online cross-sectional study

BACKGROUND

This study aimed to examine factors associated with postpartum depression (PPD) symptoms during the COVID-19 pandemic among postpartum women in five countries, a subject that has not been investigated thus far.

METHODS

A multi-country, cross-sectional, online survey was conducted with a convenience sample of 3,523 postpartum women in Brazil, South Korea, Taiwan, Thailand, and the United Kingdom, from July to November 2021. Sociodemographic and obstetric data, food insecurity, COVID-19 positive status, COVID-19 vaccination, infant feeding, breastfeeding belief score, and social support were investigated. PPD and social support were measured using the Edinburgh Postnatal Depression Scale and Maternal Social Support Scale, respectively. Descriptive statistics, chi-squared tests, and t-tests were used to identify associations with PPD symptoms. A binary logistic regression model was used to identify explanatory factors associated with PPD and adjusted odds ratios (OR) and 95% confidence intervals (CIs) were calculated.

RESULTS

Women in Taiwan (AOR = 0.5; 95%CI 0.34, 0.73) and Thailand (AOR = 0.68; 95%CI 0.46, 0.99) had a lower risk of PPD symptoms than those in Brazil. In addition, women with planned pregnancies had a lower risk of PPD (AOR = 0.74; 95%CI 0.60, 0.91). Younger women (AOR = 1.62; 95%CI 1.05, 2.51), health problems during pregnancy, delivery, or postpartum (AOR = 1.71; 95%CI 1.42, 2.06), and no change or worse food insecurity during COVID-19 (AOR = 1.66; 95%CI 1.21, 1.27 for no change and AOR = 1.68; 95%CI 1.27, 1.23, respectively) presented a higher likelihood of having PPD. Feeding babies with expressed human milk (AOR = 1.25; 95%CI 1.03, 1.50) and/or complementary food (AOR = 1.51; 95%CI 1.17, 1.94) were associated with PPD symptoms. Women who received low (AOR = 7.74; 95%CI 5.43, 11.03) or medium support (AOR = 3.25; 95%CI 2.71, 3.88) had higher likelihoods of PPD.

CONCLUSION

PPD symptoms during the pandemic were high in young women, particularly Brazilian women, with health problems in the puerperal pregnancy cycle who fed their babies expressed breast milk and/or complementary food. Low social support also impacted PPD symptoms. This study highlights the need for the professional screening for PPD and provision of virtual or personal support.

ABM Clinical Protocol #37: Physiological Infant Care-Managing Nighttime Breastfeeding in Young Infants

A central goal of the Academy of Breastfeeding Medicine (ABM) is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient. The ABM empowers health professionals to provide safe, inclusive, patient-centered, and evidence-based care. Pregnant and lactating people identify with a broad spectrum of genders, pronouns, and terms for feeding and parenting. There are two reasons ABM's use of gender-inclusive language may be transitional or inconsistent across protocols. First, gender-inclusive language is nuanced and evolving across languages, cultures, and countries. Second, foundational research has not adequately described the experiences of gender-diverse individuals. Therefore, ABM advocates for, and will strive to use language that is as inclusive and accurate as possible within this framework. For more explanation, please read ABM Position Statements on Infant Feeding and Lactation-Related Language and Gender (https://doi.org/10.1089/bfm.2021.29188.abm) and Breastfeeding As a Basic Human Right (https://doi.org/10.1089/bfm.2022.29216.abm).
