Breastfeeding cessation and symptoms of anxiety and depression: a longitudinal cohort study

Psychological factors affecting breastfeeding during the perinatal period in the UK: an observational longitudinal study

BACKGROUND

Identifying the behavioral determinants of breastfeeding is an important step toward increasing breastfeeding rates, but studies often adopt a limited measurement model. We aimed to identify, in a British population, which behavioral and psychological factors, assessed throughout the perinatal period, were most reliably associated with intent to breastfeed and breastfeeding at 1 and 6 months.

METHODS

This is an observational longitudinal study of a diverse (35.1% non-white) community sample of N = 222 pregnant women attending a maternity hospital in the UK. We assessed self-reported anxiety and depressive symptoms, stressful life events, and coping at 20-22, 28 and 36 weeks gestation and 1 and 6 months postnatally; intention to breastfeed was assessed at 20 weeks gestation. Breastfeeding was assessed at one and six months post-partum. We modelled the associations with logistic regressions, adjusting for socio-demographics.

RESULTS

Antenatal and post-partum depressive and anxiety symptoms were not reliably associated with breastfeeding behavior up to 6 months. In contrast, breastfeeding intention, which was not associated with affective symptoms, stress, and coping, was a reliable predictor of breastfeeding after adjusting for covariates. The association between intention to breastfeed and breastfeeding behavior was not moderated by behavioral/psychological factors (p > 0.5).

CONCLUSIONS

This study extends previous findings about the importance of intention to breastfeed to breastfeeding behaviour and suggests that suffering from affective symptoms does not inhibit breastfeeding. Antenatal intention to breastfeed can play a crucial role in shaping both maternal and child health outcomes.

Investigation of the Relationship Between Weaning Readiness and Maternal Depression: Cross-Sectional Online Survey

Background/Objectives: The initiation and continuation of breastfeeding are just as crucial as its conclusion. This study aimed to explore the connection between maternal depression and readiness for weaning. Although previous studies have examined maternal depression in the context of breastfeeding initiation and continuation, limited research has explored its role in weaning readiness. This study seeks to address this gap by investigating the psychological and emotional aspects of weaning in primiparous mothers. Methods: This descriptive cross-sectional study was conducted between May and July 2024 through online interviews. The descriptive information form, Readiness for Weaning Scale (RWS), and Beck Depression Inventory-II (BDI-II) were used for data collection. The sample included 83 primiparous mothers with a healthy pregnancy, no prior depression diagnosis or breastfeeding experience, and a baby aged 18 months or older. Statistical analyses were conducted to examine the correlation between RWS and BDI-II scores. Results: Participants' mean age was 31.95 ± 5.25 years, and the average breastfeeding duration was 17.83 ± 9.79 months. Among the mothers, 63.9% reported readiness to wean, with a significant relationship between the RWS and readiness. Emotional challenges included sadness (62.7%), fear of damaging the maternal bond (45.8%), and feelings of deprivation (34.9%). The mean RWS score was 65.64 ± 11.31, while the mean BDI-II score was 9.67 ± 7.02. Higher depression scores were associated with lower readiness for weaning. Conclusions: Midwives play a crucial role in supporting mothers during weaning. This study highlights the need for targeted interventions to address maternal emotional well-being during this transition. Future research should explore culturally sensitive approaches to improve support mechanisms for mothers experiencing psychological distress while weaning.

Necrotizing fasciitis of the breast in a breastfeeding mother: A case report

INTRODUCTION

Necrotizing fasciitis (NF) is a rapidly progressive life-threatening infection involving necrosis of subcutaneous tissues and fascia. Though it mainly affects the extremities, perineum and abdominal wall, it rarely affects the breast.

PRESENTATION OF CASE

A 30-year-old woman on postpartum day seven presented with one-day history of fever with chills and rigors and painful, swollen and tender left breast. Although the initial diagnosis was mastitis, the disease progressively worsened with the breast developing ischaemic necrotic areas in the lower quadrants and nipple areolar region. Therefore, a clinical diagnosis of breast necrotizing fasciitis was made. She was managed with broad-spectrum antibiotics, hypertonic saline dressings and supportive care and debridement. Cultures from wound swabs showed multi-resistant polymicrobial growth.

DISCUSSION

Necrotizing fasciitis of the breast is mainly reported following pregnancy like in our patient. The diagnosis is mainly clinical with the help of laboratory and radiological investigations. Broad spectrum IV antibiotics, surgical/chemical debridement, VAC dressings and supportive care are the main principles of managing necrotizing fasciitis. Alongside this, psychological support was crucial in the management of our patient.

CONCLUSION

We have reported rare presentation of a breastfeeding mother presenting with NF. We were able to successfully manage due to early identification and appropriate management.

Acute Onset or Worsening of Psychiatric Symptoms Following Breastfeeding Cessation: An Illustrative Case and Literature Review

BACKGROUND

Breastfeeding shares a complex, occasionally contradictory relationship with maternal mental health. Both positive and negative mood impacts have been noted in relation to breastfeeding initiation as well as cessation. Though popular magazines and online forums discuss the onset of psychiatric symptoms following weaning, there is limited medical literature detailing this relationship.

OBJECTIVE

To increase awareness regarding psychiatric symptom development in the context of breastfeeding cessation.

METHODS

We describe the case of a patient who developed psychiatric symptoms shortly after weaning, including acute-onset insomnia and worsening anxiety. A literature review of psychiatric symptom development following breastfeeding cessation was conducted using the search engines PubMed, PsycINFO (EBSCOhost), and Embase. Search terms included controlled vocabulary, keywords (within title and abstract fields), synonyms, and related concepts for postpartum period, postpartum depression, postpartum anxiety, breastfeeding cessation, breastfeeding weaning, lactation, dysphoric milk ejection reflex, and insomnia. Relevant case reports were reviewed and compared to this case. Information including the patient's age, psychiatric symptoms, past psychiatric history, medical workup, treatment, and outcome was extracted from each article.

RESULTS

Nine patients who developed psychiatric symptoms following breastfeeding cessation were identified in six case reports. Three patients experienced recurrent symptoms in multiple pregnancies. This led to documentation of 13 discrete postweaning syndromes. All cases involved either first-time parents, those new to breastfeeding, or those experiencing symptoms during multiple weaning periods. Synthesizes data from the article review. As with our case, 11 clinical cases describe sleep changes (primarily insomnia) and 4 discuss anxiety symptoms. Treatment varied based upon symptoms experienced, with no consistently effective treatments identified across cases.

CONCLUSIONS

This case of unspecified insomnia and anxiety disorders following abrupt weaning adds to the limited literature in the field and suggests that physiologic and psychologic factors associated with breastfeeding cessation may play a role in the development or worsening of postpartum mood disorders. Intensive psychiatric treatment resulted in resolution of the patient's symptoms. The relationship between weaning and psychiatric disorders is evident in the lay press but is underrepresented in medical literature. Additional research is needed to better understand this relationship so that physicians can counsel, diagnose, and treat patients more effectively.

Midwifery continuity of care for women with perinatal mental health conditions: A cohort study from Australia

BACKGROUND

Perinatal mental health (PMH) conditions are associated with adverse outcomes such as maternal suicide, preterm birth and longer-term childhood sequelae. Midwifery continuity of care (one midwife or a small group of midwives) has demonstrated benefits for women and newborns, including a reduction in preterm birth and improvements in maternal anxiety/worry and depression.

AIM

To determine if midwifery care provided through a Midwifery Group Caseload Practice model is associated with improved perinatal outcomes for women who have anxiety and depression and/or other perinatal mental health conditions. An EPDS ≥ 13, and/or answered the thought of harming myself has occurred to me and/or women who self-reported a history compared to standard models of care (mixed midwife/obstetric fragmented care).

METHODS

A retrospective cohort study using data routinely collected via an electronic database between 1 January 2018 31st of January 2021. The population were women with current/history of PMH, who received Midwifery Caseload Group Practice (MCP), or standard care (SC). Data were analysed using descriptive statistics for maternal characteristics and logistic regression for birth outcomes. One-to-one matching of the MCP group with the SC group was based on propensity scores.

RESULTS

7,359 births were included MCP 12% and SC 88%. Anxiety was the most common PMH with the same proportion affected in MCP and SC. Adjusted odds of preterm birth and adverse perinatal outcomes were lower in the MCP group than the SC group (aOR (95%CI): 0.77 (0.55, 1.08) and 0.81 (0.68, 0.97), respectively) and higher for vaginal birth and full breastfeeding (aOR (95% CI): 1.87 (1.60, 2.18) and 2.06 (1.61, 2.63), respectively). In the matched sample the estimate of a relationship between MCP and preterm birth (aOR (95% CI): 0.88 (0.56, 1.42), adverse perinatal outcomes (aOR (95% CI): 0.83 (0.67, 1.05)) and breastfeeding at discharge (aOR (95% CI): 1.82 (1.30, 2.51)), stronger for vaginal birth (aOR (95% CI): 2.22 (1.77, 2.71)).

CONCLUSION

This study supports positive associations between MCP and breastfeeding and vaginal birth. MCP was also associated with lower risk of adverse perinatal outcomes, though in the matched sample with a smaller sample size, the confidence interval included 1. The direction of the association MCP and preterm birth was negative (protective). However, in the matched sample analysis, the confidence interval was wide, and the finding was also consistent with no benefit from MCP. Randomised controlled trials are required to answer questions around preterm birth and adverse perinatal outcomes and further research is being planned.

The Breastfeeding Experiences of Mother-Infant Dyads and the Effects of an FMR1 Mutation

This study examined the early breastfeeding experiences of mothers with an FMR1 premutation (FXPM) and their infants with and without fragile X syndrome (FXS) to identify early feeding needs and potential opportunities for intervention. Data collection occurred through a retrospective national survey that captured data on breastfeeding experiences and co-occurring conditions of mother and child. Participants were 246 mothers with an FXPM. Of their 384 infants, 287 had FXS and 97 were unaffected (i.e., they did not have FXS or an FXPM). Unaffected infants had a longer breastfeeding duration relative to infants with FXS, and infants of mothers who had postpartum depression (PPD). Additionally, infants who were reported to display aggressiveness towards others later in childhood had a shorter breastfeeding duration than those who did not go on to display aggression. Approximately 42% percent of mothers reported difficulties with breastfeeding infants with FXS compared to only 17% of unaffected infants. The most common reason for breastfeeding cessation for mothers of children with FXS was perceived difficulties in breastfeeding for the child (37%), whereas the most common reason for mothers of unaffected infants was a personal choice to stop (37%). This study provides preliminary evidence that infants with FXS show early phenotypes that make breastfeeding more difficult. Future research should investigate whether interventions for infants with FXS could improve breastfeeding outcomes.

Factors influencing prophylactic surgical intervention in women with genetic predisposition for breast cancer

INTRODUCTION

In the United States, 5%-10% of breast cancer cases are due to genetic predisposition. Among this population, prophylactic mastectomy is viable risk-reducing option.

OBJECTIVE

The objective of this study is to understand the timing to prophylactic mastectomy in patients with genetic predisposition to breast cancer and uncover factors influencing this decision.

METHODS

This study is a retrospective review of patients diagnosed with genetic predisposition for breast cancer from 2010 to 2020.

RESULTS

In a cohort of 506 patients with genetic predisposition for breast cancer, 154 (30.4%) underwent prophylactic mastectomy, the remainder opted for surveillance alone. The median time from diagnosis to mastectomy was 1.1 years (IQR, 0.5-3.1 years). During the surveillance period, 118 patients (33.5%) underwent breast biopsy. Of the patients with benign or atypical findings, 35 (36.8%) pursued prophylactic mastectomy, a median of 0.5 years (IQR, 0.2-1.6 years) after their gene diagnosis. The most common factor impacting the decision to undergo prophylactic mastectomy was having a family member with cancer (54.7%) followed by a personal diagnosis of other cancer(s) (27.5%).

CONCLUSION

Understanding the factors influencing the decision to undergo prophylactic surgery will allow for more effective shared decision-making for primary care providers, breast surgeons, and reconstructive surgeons.

The multiple mediation model of social support and postpartum anxiety symptomatology: the role of resilience, postpartum stress, and sleep problems

OBJECTIVE

This study aimed to assess the prevalence of postpartum anxiety and the factors influencing it, while also exploring the multiple mediating roles of related factors between social support and postpartum anxiety symptomatology among postpartum women in China.

METHODS

Between April and August 2023, we recruited a total of 824 postpartum women through a convenience sampling method. These participants completed a series of general survey questionnaires and were evaluated using the depression anxiety stress scale, perceived social support scale, 10-item Connor-Davidson resilience scale, maternal postpartum stress scale, and Pittsburgh sleep quality index. Additionally, we employed a hierarchical multiple regression model to investigate the relevant factors and mediators of postpartum anxiety symptomatology. A structural equation model was used to examine the mediating role of resilience, postpartum stress, and sleep problems in the relationship between social support and postpartum anxiety symptomatology.

RESULTS

Our study found a postpartum anxiety symptomatology prevalence rate of 18.40%. The factors influencing postpartum anxiety symptomatology included age, education of their husband, mastitis, social support, resilience, postpartum stress, and sleep problems. Through a multiple mediation analysis, we found that resilience, postpartum stress, and sleep problems completely mediated the effects of social support on postpartum anxiety symptomatology, with the mediating effect accounting for 83.57% of the total effect.

CONCLUSION

The multiple mediation analysis revealed that among postpartum women, the impact of social support on postpartum anxiety symptomatology is channeled through resilience, postpartum stress, and sleep problems. Therefore, enhancing social support, resilience, postpartum stress, and sleep problems might alleviate postpartum anxiety symptomatology.

Stimulation Therapy to Induce Mothers: Protocol for a Multicenter Randomized Controlled Trial

BACKGROUND

More than 1 million women have their labor induced in the United States each year, and synthetic oxytocin infusion is the most common method used. However, compared to spontaneous labor, medical induction is resource intensive, has increased obstetric risks, and is associated with less successful breastfeeding. In contrast to the endogenous oxytocin hormone, which is released in a pulsatile fashion in the brain, synthetic oxytocin is continuously infused intravenously, resulting in important limitations related to efficacy, safety, and cost. Akin to spontaneous labor contractions, infant suckling of the breast nipple is known to stimulate the pulsatile release of endogenous oxytocin from the posterior pituitary gland. Nipple stimulation therapy via an electric breast pump similarly stimulates endogenous oxytocin release and may be a favorable inpatient method for patients undergoing labor induction.

OBJECTIVE

This study aims to examine whether inpatient nipple stimulation therapy is an efficacious labor induction method that increases the likelihood of spontaneous vaginal delivery and sustained breastfeeding and determine whether it is a cost-effective approach.

METHODS

This is a multicenter, pragmatic, open-label, parallel-group randomized controlled trial of nulliparous patients with singleton gestations ≥36 weeks undergoing labor induction. This trial compares inpatient nipple stimulation therapy via an electric breast pump versus immediate synthetic oxytocin infusion without nipple stimulation. This trial including 988 nulliparas will provide adequate statistical power to detect clinically meaningful differences in delivery mode and breast milk as the sole source of nutrition for newborns at hospital discharge or 72 hours after birth.

RESULTS

The project received pilot funding in 2021 and full funding in 2023. Enrollment for this study began in November 2021 at a single site, and as of May 2024, recruitment is underway at 3 study sites. It is anticipated that enrollment will be completed by late 2026.

CONCLUSIONS

Successful completion of this trial will provide rigorous data to determine whether inpatient nipple stimulation therapy with an electric breast pump can improve the way we induce labor and positively impact breastfeeding success and early infant nutrition through lactation.

Disturbances of the gut microbiota-derived tryptophan metabolites as key actors in vagotomy-induced mastitis in mice

Previous studies have demonstrated that gut microbiota dysbiosis promotes the development of mastitis. The interaction of the vagus nerve and gut microbiota endows host homeostasis and regulates disease development, but whether the vagus nerve participates in the pathogenesis of mastitis is unclear. Here, vagotomized mice exhibit disruption of the blood-milk barrier and mammary gland inflammation. Notably, mastitis and barrier damage caused by vagotomy are dependent on the gut microbiota, as evidenced by antibiotic treatment and fecal microbiota transplantation. Vagotomy significantly alters the gut microbial composition and tryptophan metabolism and reduces the 5-hydroxyindole acetic acid (5-HIAA) level. Supplementation with 5-HIAA alleviates vagotomy-induced mastitis, which is associated with the activation of the aryl hydrocarbon receptor (AhR) and subsequent inhibition of the NF-κB pathway. Collectively, our findings indicate the important role of the vagus-mediated gut-mammary axis in the pathogenesis of mastitis and imply a potential strategy for the treatment of mastitis by targeting the vagus-gut microbiota interaction.

Maternal Psychological Well-Being as a Protector in Infantile Colic

(1) Background: Infantile colic (IC) is a functional gastrointestinal disorder that affects around 20% of infants, and postpartum (PPD) depression is a common disorder that affects between 15 and 22% of mothers. In this study, our objective was to evaluate the relationship between the maternal psychological state in the first postpartum year and IC, with the aim of assessing the importance of feeding type in infants and maternal well-being. (2) Methods: A cross-sectional study was conducted in women in their first year postpartum. Demographic, medical, and obstetric data of the mothers and infants were collected, and the type of feeding was identified. The emotional status of the mother was evaluated using the Edinburgh Postnatal Depression Scale (EPDS), and the Infant Colic Severity Questionnaire (ICSQ) was used for IC diagnosis. (3) Results: A total of 528 women were analyzed, of which 170 (32%) were diagnosed with possible PPD. Two-thirds of the women without depression breastfed their babies on demand; therefore, we report that exclusive breastfeeding (EBF) appears to reduce the risk of possible PPD (p < 0.001; OR = 2.353). IC was present in 39% of babies, and around 70% of babies without colic were breastfed on demand. Infants who were not exclusively breastfed showed almost double the risk of developing colic (p = 0.016; OR = 1.577). There was a significant association between the EPDS and ICSQ scores (p < 0.001). More than half of the women with PPD had babies with colic. However, our results show that 75% of babies without colic had mothers who reported optimal postpartum emotional well-being (p < 0.001; OR = 2.105). (4) Conclusions: The results of this study suggest that postpartum maternal psychological well-being reduces the risk of IC. Therefore, we report that EBF on demand, together with a healthy emotional state in new mothers, may be a protective factor against colic in infants.

Prevalence and associated factors of maternal depression among mothers of children with undernutrition at comprehensive specialized hospitals in Northwest Ethiopia in 2023: a cross-sectional study

Background

Malnutrition is one of the most significant child health problems in developing countries, accounting for an estimated 53% of child deaths per year. Depression is the leading cause of disease-related disability in women and adversely affects the health and well-being of mothers and their children. Studies have shown that maternal depression has an impact on infant growth and nutritional status. However, evidence is scarce regarding the relationship between maternal depression and child malnutrition.

Objectives

The general objective of this study was to assess the prevalence and associated factors of maternal depression among mothers of undernourished children at comprehensive specialized hospitals in Northwest Ethiopia in 2023.

Methods

An institution-based cross-sectional study was conducted among 465 participants. Outcome variables were assessed using a Patient Health Questionnaire-9 (PHQ-9). Data were analyzed using SPSS-25. Bivariate and multivariable logistic regression analyses were conducted. Variables with a p-value less than 0.05 were considered statistically significant with a corresponding 95% confidence interval (CI).

Results

The prevalence of maternal depression among mothers of children with undernutrition was 36.4% (95% CI = 32%-41%). According to a multivariate analysis, lack of maternal education (adjusted odds ratio [AOR] = 2.872, 95% CI = 1.502-5.492), unemployment (AOR = 2.581, 95% CI = 1.497-4.451), poor social support (AOR = 2.209, 95% CI = 1.314-3.713), perceived stigma (AOR = 2.243, 95% CI = 1.414-3.560), and stunting (AOR = 1.913, 95% CI = 1.129-3.241) were factors significantly associated with maternal depression.

Conclusion

The overall prevalence of maternal depression was higher among mothers of children with undernutrition. This higher prevalence was associated with several factors, including lack of education, unemployment, poor social support, high perceived stigma, and stunted physical growth in the children themselves. To decrease maternal depression, we can address these factors by increasing the level of maternal education and employment opportunities, strengthening social support systems, reducing stigma, and providing interventions to reduce stunting.

Milk levels of transforming growth factor beta 1 identify mothers with low milk supply

Human milk is optimal for infant nutrition. However, many mothers cease breastfeeding because of low milk supply (LMS). It is difficult to identify mothers at risk for LMS because its biologic underpinnings are not fully understood. Previously, we demonstrated that milk micro-ribonucleic acids (miRNAs) may be related to LMS. Transforming growth factor beta (TGFβ) also plays an important role in mammary involution and may contribute to LMS. We performed a longitudinal cohort study of 139 breastfeeding mothers to test the hypothesis that milk levels of TGFβ would identify mothers with LMS. We explored whether TGFβ impacts the expression of LMS-related miRNAs in cultured human mammary epithelial cells (HMECs). LMS was defined by maternal report of inadequate milk production, and confirmed by age of formula introduction and infant weight trajectory. Levels of TGF-β1 and TGF-β2 were measured one month after delivery. There was a significant relationship between levels of TGF-β1 and LMS (X2 = 8.92, p = 0.003) on logistic regression analysis, while controlling for lactation stage (X2 = 1.28, p = 0.25), maternal pre-pregnancy body mass index (X2 = 0.038, p = 0.84), and previous breastfeeding experience (X2 = 7.43, p = 0.006). The model accounted for 16.8% of variance in the data (p = 0.005) and correctly predicted LMS for 84.6% of mothers (22/26; AUC = 0.72). Interactions between TGF-β1 and miR-22-3p displayed significant effect on LMS status (Z = 2.67, p = 0.008). Further, incubation of HMECs with TGF-β1 significantly reduced mammary cell number (t = -4.23, p = 0.003) and increased levels of miR-22-3p (t = 3.861, p = 0.008). Interactions between TGF-β1 and miR-22-3p may impact mammary function and milk levels of TGF-β1 could have clinical utility for identifying mothers with LMS. Such information could be used to provide early, targeted lactation support.

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.

Quality of mother-infant interaction, breastfeeding, and perinatal mental health

INTRODUCTION

The quality of mother-infant interactions is crucial for child development. Studies show that breastfeeding contributes to maternal sensitivity and the development of a positive mother-infant bond. Maternal mental health difficulties negatively impact both maternal sensitivity and breastfeeding. Thus, it is unclear whether breastfeeding contributes to the quality of mother-infant interactions independent from mental health. The purpose of this study is to examine the contribution of exclusive breastfeeding at 3 months postpartum to the quality of the mother-infant relationship at 6 months postpartum, controlling for maternal mental health in a community sample of mothers in Chile.

MATERIALS AND METHOD

Eighty women completed self-report measures of mental health and breastfeeding during the third trimester of pregnancy and 3 and 6 months postpartum. At 6 months after childbirth, the mother-infant interaction was assessed by coding a free-play session between mothers and infants. Logistic regression analysis was used to examine the contribution of breastfeeding practices and mental health to the quality of mother-infant interactions.

RESULTS

Exclusive breastfeeding at 3 months postpartum increased the likelihood of displaying positive mother-infant interactions controlling for maternal mental health. Mothers who continued to breastfeed at 6 months postpartum reported less symptoms of antenatal depression and anxiety and higher levels of sensitivity and cooperation towards their infants.

CONCLUSION

Breastfeeding contributes to maternal sensitivity and cooperation even when controlling for maternal mental health. Implications for health practitioners and limitations due to the sample characteristics are discussed.

Barriers to exclusive breastfeeding practice among HIV-positive mothers in Tanzania. An exploratory qualitative study

BACKGROUND

Ensuring optimal nutrition through early breastfeeding is vital for infant mental development and overall health. HIV infections complicate decisions regarding exclusive breastfeeding, jeopardizing effective infant and young child feeding, which affects nutrition and health outcomes. Recognizing the lack of evidence on barriers to infant feeding in the context of HIV in Tanzania, this study was conducted to explore individual, household, and community obstacles in the Ilala district, Dar es Salaam.

MATERIALS AND METHODS

A case study design employing a qualitative approach was used. The study was executed at the Reproductive and Child Health (RCH) Clinic within Amana Regional Referral Hospital, Mnazi Mmoja Health Centre, and Buguruni Health Centre. Data collection ensued through the purposive sampling of healthcare providers and HIV-positive mothers, utilizing in-depth interview techniques. The textual data accrued were analyzed using inductive and deductive content analysis strategies, thereby enabling the delineation and formulation of principal thematic constructs.

RESULTS

The study involved interviews with twenty-seven key informants, encompassing HIV-positive mothers, nurses, clinicians, and community-based healthcare workers. The analysis of these interviews resulted in the identification of three major themes. Firstly, individual barriers to exclusive breastfeeding were delineated, encompassing sub-themes such as occupation-related hectic schedules, early motherhood-related non-compliance to safe infant feeding directives, postpartum depression, and issues related to breast sores and abscesses. Secondly, household-level barriers were identified, highlighting challenges like food insecurity and inaccessibility to key resources, the influence of male partners and family members on decision-making, and barriers arising from non-disclosure of HIV status affecting Exclusive Breastfeeding (EBF) support. Lastly, community-level barriers were explored, revealing a sub-theme related to the low retentivity of HIV-positive women in the Prevention of Mother-to-Child Transmission (PMTCT) programs.

CONCLUSIONS

Individual barriers encompass practical, psychological, and physical challenges, while household-level obstacles include food insecurity, limited resources, and family dynamics influencing decisions. At the community level, there's a concern about the low retentivity of HIV-positive women in PMTCT programs, indicating broader societal challenges in supporting exclusive breastfeeding. There is a need for tailored interventions at individual, household, and community levels to promote and support optimal infant feeding practices among HIV-positive women.

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.

The Effect of the Number of Breastfeeding Sessions per Day in the Early Postpartum Period on Postpartum Depression Scores Among Pregnant Women Without Risk Factors for Depression: A Retrospective Cohort Study

Background: The objective of this study was to investigate the relationship between the Edinburgh Postpartum Depression Scale (EPDS) score on the 10th day postpartum and the number of breastfeeding sessions per day among puerperal women (with no known depression risk factors and a low [<10] EPDS score after delivery). Materials and Methods: A total of 1,451 nulliparous, 37- to 41-week pregnant women who gave birth between August 2020 and August 2022 and who underwent routine postpartum checkups on the 10th day after delivery were included in this study. Pregnant women with risk factors for depression before pregnancy, during pregnancy, and after delivery were not included. Patients with an EPDS score of ≥10 after delivery were excluded from the study. On the 10th day after birth, the mean number of breastfeeding sessions per day of the population in the study was determined. Patients with a number of breastfeeding sessions per day above the mean value were classified as Group A (n = 45), and those with values below the mean were classified as Group B (n = 67). Results: The mean number of breastfeeding sessions per day was 10.15. The EPDS scores of Group A (6 [0-19]) were significantly lower than those of Group B (8 [0-20]) (p < 0.05). A negative linear relationship was found between the number of breastfeeding sessions per day and the EPDS scores on the 10th day postpartum (p < 0.05). No statistically significant difference was found between the EPDS scores and the education status, age, or gestational week of the patients (p > 0.05). There was no statistically significant difference between the number of breastfeeding sessions per day and the education status or age of the patients (p > 0.05). Conclusions: Higher number of breastfeeding sessions per day is associated with less risk of maternal postpartum depression. There is a need for new studies on the consequences of the number and quality of breastfeeding sessions.

Infant and Young Child Feeding in the Context of HIV: An Exploration of Barriers in Exclusive Breastfeeding Practice in Dar Es Salaam, Tanzania

Background

Ensuring optimal nutrition through early breastfeeding is vital for infant mental development and overall health. HIV infections complicate decisions regarding exclusive breastfeeding, jeopardizing effective infant and young child feeding, which affects nutrition and health outcomes. Recognizing the lack of evidence on barriers to infant feeding in the context of HIV in Tanzania, this study was conducted to explore individual, household, and community obstacles in the Ilala district, Dar es Salaam.

Methods

The study used a hospital-based qualitative approach, focusing on HIV-positive mothers with infants aged 3-6 months in Dar es Salaam city. This involved reviewing mothers' files, conducting interviews with them, and interviewing Reproductive and Child Health clinics (RCH) and community healthcare providers. In total, 27 In-depth interviews were conducted until data saturation was reached, and thematic analysis was used to analyze collected data.

Findings

The study identified various barriers to exclusive breastfeeding, encompassing individual factors like work schedules, postpartum depression, and breast conditions. On the household level, barriers included limited access to resources, family influence, and HIV status disclosure reluctance due to stigma. In the community, low retention in the Prevention of Mother-to-Child Transmission (PMTCT) programs plays a pivotal role in hindering exclusive breastfeeding support for HIV-positive mothers.

Conclusion and Recommendations

HIV-positive mothers face diverse barriers ranging from individual, household, and community-based barriers. Policies supporting breastfeeding, early detection of postnatal depression and breast problems, and peer support for young mothers are of paramount importance. Food insecurity and HIV stigma should be tackled through income-generating activities, family involvement in PMTCT programs, and awareness campaigns. Community-based counselors play a crucial role in supporting HIV-positive mothers in their exclusive breastfeeding journey to improve PMTCT care retention.

Towards Preventative Psychiatry: Concurrent and Longitudinal Predictors of Postnatal Maternal-Infant Bonding

Maternal-infant bonding is important for children's positive development. Poor maternal-infant bonding is a risk factor for negative mother and infant outcomes. Although researchers have examined individual predictors of maternal-infant bonding, studies typically do not examine several concurrent and longitudinal predictors within the same model. This study aimed to evaluate the unique and combined predictive power of cross-sectional and longitudinal predictors of maternal-infant bonding. Participants were 372 pregnant women recruited from an Australian hospital. Data were collected from mothers at antenatal appointments (T0), following their child's birth (T1), and at a laboratory assessment when their child was 5-11-months-old (T2). Poorer bonding at T2 was predicted at T0 by younger maternal age, higher education, and higher antenatal depressive symptoms. Poorer bonding at T2 was predicted at T1 by younger maternal age, higher education, and higher postnatal depressive symptoms. Poorer bonding at T2 was predicted at T2 by younger maternal age, higher education, higher postnatal depression symptoms, higher concurrent perceived social support, and more difficult infant temperament, when controlling for child age at T2. To promote positive maternal-infant bonding, global and targeted interventions in the perinatal period may benefit from targeting maternal psychopathology, perceived lack of social support, and coping with difficult infant temperament.

Labour agentry and subsequent adverse mental health outcomes: A follow-up study of the ARRIVE Trial

OBJECTIVE

Labour can be traumatic for women who perceive they are not involved in decisions affecting their care during labour. Our objective was to assess the relation between labour agentry and subsequent mental health.

DESIGN

Follow-up cohort study.

SETTING

U.S. Tertiary care center.

POPULATION

Participants from Utah who participated in the ARRIVE (A Randomized Trial of Induction Versus Expectant Management) trial.

METHODS

During the ARRIVE trial, participants completed the Labor Agentry Scale twice, a validated questionnaire measuring perceived control of patients during childbirth. ARRIVE participants from Utah subsequently were asked to complete questions about mental health history and stressful events occurring since the trial, as well as surveys including the Primary Care Posttraumatic Stress Disorder (PC-PTSD) screen, Edinburgh Postnatal Depression Scale (EPDS) and Generalised Anxiety Disorder-7 (GAD-7) screen. The lower quartile of both agentry measurements defined a person's ordinal agentry category, used for assessing cohort characteristics by exposure category. Continuous minimum agentry was included in adjusted modelling.

MAIN OUTCOME MEASURES

The primary outcome was a mental health composite including a positive screen for depression, anxiety, or PTSD or self-report of a diagnosis or exacerbation since their delivery.

RESULTS

In all, 766 of 1042 (74%) people responded to the survey (median 4.4, range 2.5-6.4 years after delivery) and 753 had complete data for analysis. In unadjusted comparisons across ordinal agentry category, lower agentry was significantly associated with the primary composite endpoint, and depressive symptoms (test of trend p = 0.003 primary, p = 0.004 depression). Lower labour agentry scores were associated with incremental odds of the primary endpoint (1 SD [24 units], adjusted odds ratio [aOR] 1.21, 95% CI 1.41-1.03), driven by depressive symptoms or self-reported diagnosis (aOR 1.25, 95% CI 1.47-1.05).

CONCLUSIONS

Lower labour agentry at the time of birth was associated with a greater risk for mental health conditions years after delivery, indicating a potential opportunity for primary prevention of subsequent depression.

Predicting intention and maintenance of breastfeeding up to 2-years after birth in primiparous and multiparous women

OBJECTIVES

Breastfeeding up to 2-years has been associated with short and long-term health benefits for both newborns and mothers. However, few women breastfeed up to 2-years after birth. This study extends previous research on the theory of planned behaviour (TPB) examining the predictors of intention and maintenance of breastfeeding up to 2-years in both primiparous and multiparous women.

DESIGN

155 pregnant women participated in this longitudinal study.

METHODS

Expectant mothers completed a questionnaire and then 2-years after the child's birth were asked to report breastfeeding behaviour. Interactions among parity and TPB constructs were examined.

RESULTS

Attitudes, descriptive and injunctive norms, and perceived behavioural control (PBC) explained 58% of the variance in mothers' intention to breastfeed. Attitudes were the strongest predictor, followed by PBC, descriptive norms and parity. A significant interaction was found between parity and PBC, showing that PBC was only a significant predictor of intention to breastfeed at 2-years in multiparous women. Intentions predicted breastfeeding behaviour at 2-years.

CONCLUSION

Promoting intentions may be a useful way to increase breastfeeding duration to 2-years and targeting attitudes and norms may be one way to increase intentions. Further, targeting PBC may also be useful to increase intentions, but only in multiparous women.

Biomarkers of Postpartum Depression: A Narrative Review

Postpartum depression (PPD) is a disorder that impairs the formation of the relationship between mother and child, and reduces the quality of life for affected women to a functionally significant degree. Studying markers associated with PPD can help in early detection, prevention, or monitoring treatment. The purpose of this paper is to review biomarkers linked to PPD and to present selected theories on the pathogenesis of the disease based on data from biomarker studies. The complex etiology of the disorder reduces the specificity and sensitivity of markers, but they remain a valuable source of information to help clinicians. The biggest challenge of the future will be to translate high-tech methods for detecting markers associated with postpartum depression into more readily available and less costly ones. Population-based studies are needed to test the utility of potential PPD markers.

Assessment of prenatal depression among U.S. pregnant women without access to paid sick leave and regular place of care: National Health Interview Survey of U.S.-born and non-U.S.-born

Prenatal depression is one of the most common risks during pregnancy. This study examined the prevalence and likelihood of prenatal depression association with sociodemographic factors, paid sick leave, and place of care among U.S. pregnant women. We conducted bivariate Chi-square tests to assess the statistical difference and multivariable logistic regression models to assess the association of prenatal depression using the National Health Interview Survey, cross-sectional data from 2010 to 2019 of pregnant women aged 18-44 years (N = 957). The prevalence of prenatal depression was 40.6%, 28.5%, and 27.2% among White, Black, and other racial pregnant women, respectively. Pregnant women with no regular/routine place of care had a prenatal depression prevalence rate of 58.1%, and those without access to paid sick leave had 46.9%. Also, pregnant women without access to paid sick leave were found to have an increased likelihood of reporting prenatal depression ([adjusted odds ratio] AOR = 2.50, 95% CI = 1.72-3.64), as well as those without a regular place of care (AOR = 2.43, 95% CI = 1.32-4.47). The findings identify factors that need to be addressed to minimize depression among U.S. pregnant women and establish the need for tailored interventions to address prenatal depression.

Associations between pressure to breastfeed and depressive, anxiety, obsessive-compulsive, and eating disorder symptoms among postpartum women

BACKGROUND

Data from qualitative interviews indicate postpartum individuals feel pressure from their healthcare providers, the media, and their partners to breastfeed their infant(s). However, the link between pressure to breastfeed and maternal mental health symptoms has not been evaluated quantitatively. The goal of the current study was to evaluate the associations between perceived pressure to breastfeed from various sources and depressive, anxiety, obsessive-compulsive, and eating disorder symptoms among postpartum individuals.

METHODS

Participants were 306 women, ages 18-39, who gave birth in the past 12 months in the United States (primarily in North Carolina). They completed an online survey about their health history (including mental health symptoms) and breastfeeding experiences.

RESULTS

Results found postpartum women perceived more pressure to breastfeed from healthcare providers and from the media compared to pressure to breastfeed from their partners. Pressure from healthcare providers was associated with depressive, obsessive-compulsive, and eating disorder symptoms, but not with anxiety symptoms. Pressure from the media was associated with only depressive and eating disorder symptoms. Pressure from partners was not significantly associated with mental health symptoms. Above and beyond the other sources of pressure, pressure from healthcare providers explained a unique proportion of variance of obsessive-compulsive and eating disorder symptoms.

LIMITATIONS

Limitations include the cross-sectional design (which limits causal interpretations), and the homogenous sample (87% identified as White).

CONCLUSIONS

Messaging and information about breastfeeding (particularly from healthcare providers) should be reviewed to determine if there is language which could be perceived as "pressure." It is important to screen for a variety of mental health symptoms, including eating disorders, in perinatal populations when discussing breastfeeding.

Heatwaves and wildfires suffocate our healthy start to life: time to assess impact and take action

Adverse environmental exposures in utero and early childhood are known to programme long-term health. Climate change, by contributing to severe heatwaves, wildfires, and other natural disasters, is plausibly associated with adverse pregnancy outcomes and an increase in the future burden of chronic diseases in both mothers and their babies. In this Personal View, we highlight the limitations of existing evidence, specifically on the effects of severe heatwave and wildfire events, and compounding syndemic events such as the COVID-19 pandemic, on the short-term and long-term physical and mental health of pregnant women and their babies, taking into account the interactions with individual and community vulnerabilities. We highlight a need for an international, interdisciplinary collaborative effort to systematically study the effects of severe climate-related environmental crises on maternal and child health. This will enable informed changes to public health policy and clinical practice necessary to safeguard the health and wellbeing of current and future generations.

Effect of positive emotion intervention during late pregnancy on improving colostrum secretion: a randomised control trial protocol

INTRODUCTION

Though evidence has revealed the beneficial effects of cognitive improvement interventions on breastfeeding, the effect of psychological interventions has rarely been studied. This study aims to test whether promoting a positive emotion intervention, 'Three Good Things' intervention, during the last trimester of pregnancy can enhance early colostrum secretion and breastfeeding behaviours by modulating the hormones associated with lactation (prolactin and insulin-like growth factor I). We will attempt to promote exclusive breastfeeding by using physiological behavioural measures.

METHODS AND ANALYSIS

This study is designed as a randomised controlled trial conducted in the Women's Hospital School of Medicine at Zhejiang University and the Wuyi First People's Hospital. The participants will be randomly divided into two groups using stratified random grouping: the intervention group will receive 'Three Good Things' intervention, while the control group will write about three things that come to mind first. These interventions will be continued from enrolment until the day of delivery. Maternal blood hormone levels will be tested approaching delivery and the following day after birth. Behavioural information about breastfeeding will be collected 1 week afterwards.

ETHICS AND DISSEMINATION

The study has been approved by the Ethics Committees of the Women's Hospital School of Medicine at Zhejiang University and the Wuyi First People's Hospital. Results will be disseminated through peer-reviewed journals or international academic conferences.

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 of psychological well-being and cognitive emotions with breastfeeding self-efficacy in mothers in the postpartum period

To determine the relationship of psychological well-being and cognitive emotion regulation and breastfeeding self-efficacy in mothers in the postpartum period. The research was designed as cross-sectional and correlational and carried out between 1 November 2021 and 1 January 2022 in the pediatric outpatient clinic of a Medical Faculty Hospital of a province in the Central Anatolian Region of Turkey. Responses from a total of 325 mothers who were in postpartum 1-6 months were analyzed. Data were collected using a Personal Information Form, the Scales of Psychological Well-Being (SPWB), the Cognitive Emotion Regulation Questionnaire (CERQ), and the Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF). The following factors were found to be important associated risk factors that negatively affected breastfeeding self-efficacy in 29% of the mothers (F = 14.536, p < .001): mothers' poor mental health, using self-blaming maladaptive cognitive coping strategy, inability to use positive reappraisal coping strategy, and feeding the baby only formula or both breast milk and formula. Weak and positive correlations were found between psychological well-being of mothers and adaptive cognitive coping subdimensions, and negative and weak correlations were found between psychological well-being of the mothers and maladaptive cognitive coping subdimensions (p < .001). Breastfeeding self-efficacy of mothers in a well psychological state, who can use adaptive cognitive coping strategies, and who exclusively breastfeed their babies is positively affected.

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.

The Relationship between Psychological Suffering, Value of Maternal Cortisol during Third Trimester of Pregnancy and Breastfeeding Initiation

Background and Objectives: Cortisol, the stress hormone, is an important factor in initiating and maintaining lactation. Maternal suffering during pregnancy is predictive for the initiation and shorter duration of breastfeeding and can also lead to its termination. The aim of this study is to evaluate the relationship between the level of salivary cortisol in the third trimester of pregnancy and the initiation of breastfeeding in the postpartum period in a cohort of young pregnant women who wanted to exclusively breastfeed their newborns during hospitalization. Materials and Methods: For the study, full-term pregnant women were recruited between January and May 2022 in the Obstetrics and Gynecology Clinic of the Mureș County Clinical Hospital. Socio-demographic, clinical obstetric and neonatal variables were collected. Breastfeeding efficiency was assessed using the LATCH Breastfeeding Assessment Tool at 24 and 48 h after birth. The mean value of the LATCH score assessed at 24 and 48 h of age was higher among mothers who had a higher mean value of salivary cortisol measured in the third trimester of pregnancy (p < 0.05). A multivariate logistic regression model was used to detect risk factors for the success of early breastfeeding initiation. Results: A quarter of pregnant women had a salivary cortisol level above normal limits during the third trimester of pregnancy. There is a statistically significant association between maternal smoking, alcohol consumption during pregnancy and the level of anxiety or depression. Conclusions: The most important finding of this study was that increased salivary cortisol in the last trimester of pregnancy was not associated with delayed initiation/absence of breastfeeding.

Breastfeeding competency and its influencing factors among pregnant women in third trimester pregnancy: a cross-sectional study

Competency is closely related to the occurrence of the behavior. Breastfeeding competence is the mastery of different breastfeeding factors which intervene in breastfeeding behavior. Breastfeeding competence could improve the breastfeeding behavior. However, few studies have paid attention to the status and the influencing factors of breastfeeding competency. The breastfeeding competency of pregnant women in third trimester pregnancy has the greatest impact on breastfeeding behavior after childbirth. Therefore, the objective of this study were to investigate the breastfeeding competency level and independent risk factors for breastfeeding competency among pregnant women in third trimester pregnancy. A cross-sectional survey method and convenience sampling method was used in the study. The general information questionnaire including age, gestational week, educational background, and so on were used to investigate the general information of pregnant women and their husbands. A breastfeeding competency scale (BCS) was used to investigate the breastfeeding competency of pregnant women. The total score of the BCS ranges from 38 to 190, with higher scores indicating greater breastfeeding competency. Lower level, medium level and higher level are 38-89, 90-140 and 141-190 respectively. Type-D Scale-14 (DS14) was used to investigate the type D personality of pregnant women. A multivariable linear regression was used to examine the independent predictors of breastfeeding competency. A total of 550 questionnaires were collected and finally 525 effective questionnaires were collected. The age of 525 pregnant women is (30.24 ± 3.954) years old. The breastfeeding competency score of pregnant women was (134 ± 19.741). Multivariable linear regression analysis showed that higher breastfeeding competency in pregnant women were reported among pregnant women who gestational age ≥ 256 days (37 weeks) (B = 8.494, p < 0.001), the previous breastfeeding experience were exclusive breastfeeding (B = 17.384, p < 0.001) and partial breastfeeding (B = 16.878, p < 0.001), participating in pregnant women school 2-3 times (B = 10.968, p = 0.013) and ≥ 5 times (B = 13.731, p = 0.034). Pregnant women with lower breastfeeding competency were found in women who were judged to have type D personality (B = - 6.358, p < 0.001). The result can explain 25.8% of the variation in the total breastfeeding competency score. This should be considered an important issue by maternal and child health care in the medical system that the moderate level of breastfeeding capacity among pregnant women. Differentiated and targeted breastfeeding support and services for pregnant women should be carried out based on influencing factors of breastfeeding competency.

Exploring the reasons why mothers do not breastfeed, to inform and enable better support

Introduction

Infant and maternal breastfeeding benefits are well documented, globally. Despite efforts to increase global breastfeeding rates, the majority of high-income settings fall short of recommended targets. Breastfeeding rates in the UK are especially poor, and physiological difficulties (e.g., inverted nipples), fail to account for the observed breastfeeding intention-behaviour gap.

Method

The current online study sought to investigate the infant feeding experiences of 624 UK formula feeding mothers, through open text survey responses.

Results

A content analysis identified the following clusters of reasons for formula feeding: Feeding Attitudes, Feeding Problems, Mental Health, and Sharing the Load.

Discussion

Feeding Attitudes explained a large percentage of reasons given for formula feeding. Recommendations are made to improve antenatal breastfeeding education and to develop an intervention with an aim to improve maternal breastfeeding attitudes and subsequent practice. Feeding Problems also explained a large portion of combination feeding and started but stopped infant feeding accounts. The current paper calls for more comprehensive and tailored antenatal breastfeeding education to refine practical breastfeeding skills necessary for successful breastfeeding establishment and maintenance. Mental Health explained relatively small coverage. Suggestions are therefore made to train mental health practitioners on infant feeding with an aim to provide more extensive support, which may serve to disrupt the bidirectional relationship between poor mental health and poor breastfeeding outcomes. Finally, Sharing the Load explained moderate coverage across never breastfed, combination fed, and started but stopped feeding groups. Recommendations are made, in light of these findings, to tighten workplace legislation to protect breastfeeding women.

Predictors of age at menopause and psychiatric symptoms among postmenopausal females in Jordan

OBJECTIVE

This study evaluated the impact of various factors on age at natural menopause as well as psychiatric symptoms including anxiety and depression among postmenopausal women in Jordan.

METHODS

A cross-sectional study was conducted and included females with natural menopause (n = 450). A structured interview-based questionnaire was used to collect data about subjects' sociodemographics, health, reproductive and environmental factors. Hospital anxiety and depression scale (HADS) was used to assess psychiatric symptoms. Factors associated with age at natural menopause, depression, or anxiety were identified.

RESULTS

The mean age at natural menopause was 49.5 ± 4.8 years. Mothers' age at menopause, the regularity of cycles, age at last pregnancy and diabetes were significant positive predictors of age at menopause (p < 0.05). The mean anxiety and depressive scores were 6.52 ± 4.26 and 6.77 ± 3.44 respectively. Age, high school education, being nonsmoker and breastfeeding history were inversely associated with anxiety but only cycle length and multiparous were positively associated with anxiety (p < 0.05). While education and being nonsmoker were negatively associated with depression, hypertension was a positive predictor.

CONCLUSIONS

The results reveal several environmental, health, and reproductive predictors of age at menopause or psychiatric symptoms among postmenopausal women in Jordan.

Work as an Understudied Driver of Racial Inequities in Breastfeeding

Breastfeeding inequities by race are a persistent public health problem in the United States. Inequities in occupation and working conditions likely contribute to relatively less breastfeeding among Black compared to White mothers, yet little research has addressed these interrelationships. Here, we offer a critical review of the literature and a conceptual framework to guide future research about work and racial inequities in breastfeeding. There is a strong public health case for promoting breastfeeding equity for mothers across race groups and occupation types. Existing theory suggests that employment opportunities and working conditions are a likely pathway that connects structural racism to Black-White breastfeeding inequities, in addition to other known factors. We propose a new conceptual model for studying the interrelationships among work, race, and breastfeeding outcomes.

Pregnancy During Surgical Training: Are Residency Programs Truly Supporting Their Trainees?

OBJECTIVE

Despite recent national improvements in family leave policies, there has been little focus on program-level support for surgical trainees. Trainees who may require clinical duty adjustments during pregnancy, who experience pregnancy loss, or who struggle with balancing work obligations with the demands of a new infant may face stigma when seeking schedule accommodations. The aim of this study was to describe program and colleague support of surgical trainees for pregnancy-related and postpartum health needs.

DESIGN

Survey questionnaire. Participants responded to multiple-choice questions about their history of pregnancy loss, their experience with reduction of clinical duties during pregnancy, and their breastfeeding experience. Those who took time off after miscarriages or reduced their clinical duties during pregnancy were asked whether they perceived their colleagues and/or program leadership to be supportive using a 4-point Likert scale (1-strongly agree, 4-strongly disagree) which was dichotomized to agree/disagree.

SETTING

Electronically distributed through social media and surgical societies from November 2020 to January 2021.

PARTICIPANTS

Female surgical residents and fellows.

RESULTS

258 female surgical residents and fellows were included. Median age was 32 (IQR 30-35) years and 76.74% were white. Of the 52 respondents (20.2%) who reported a miscarriage, 38 (73.1%) took no time off after pregnancy loss, including 5 of 10 women (50%) whose loss occurred after 10 weeks' gestation. Of the 14 residents who took time off after a miscarriage, 4 (28.6%) disagreed their colleagues and/or leadership were supportive of time away from work. Among trainees who reported at least 1 live birth, only 18/114 (15.8%) reduced their work schedule during pregnancy. Of these, 11 (61.1%) described stigma and resentment from colleagues and 14 (77.8%) reported feeling guilty about burdening their colleagues. 100% of respondents reported a desire to breastfeed their infants, but nearly half (46.0%) were unable to reach their breastfeeding goals. 46 (80.7%) cited a lack of time to express breastmilk and 23 (40.4%) cited inadequate lactation facilities as barriers to achieving their breastfeeding goals.

CONCLUSIONS

A minority of female trainees takes time off or reduces their clinical duties for pregnancy or postpartum health needs. National parental leave policies are insufficient without complementary program-level strategies that support schedule adjustments for pregnant trainees without engendering a sense of resentment or guilt for doing so. Surgical program leaders should initiate open dialogue, proactively offer clinical duty reductions, and ensure time and space for lactation needs to safeguard maternal-fetal health and improve the working environment for pregnant residents.

Mental Health Benefits of Breastfeeding: A Literature Review

Pregnancy is typically viewed as a time of emotional well-being for prospective mothers, but for some, this period can negatively impact mental health. However, the relationship between postpartum mental health and breastfeeding is not clearly understood. Considering that many health authorities recommend breastfeeding, clearly defining this relationship is important. This review aims to illustrate the effects that breastfeeding has on the mental health of postpartum mothers. An extensive computerized search was performed through databases of PubMed, CINAHL, and Medline. All studies conducted to determine the effects of breastfeeding on mental health were screened and included in this review. Search terms related to breastfeeding, postpartum, and mental health were used. This review on breastfeeding and postpartum depression (PPD) begins by discussing the correlation between lactation and the maternal stress response. Another component discussed is the duration of breastfeeding and its importance in limiting PPD symptoms. The review then shifts to focus more on the psychological aspects of breastfeeding, notably on changes to the sleep-wake cycle and mother-infant interactions. The final part of the review emphasizes the danger that early breastfeeding cessation imposes on a mother’s mental health, portraying how prenatal and early-onset postpartum depression may lead to early breastfeeding cessation. This composite collection of studies clarifies the importance of breastfeeding in reducing the incidence and severity of maternal postpartum depression.

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.

Maternal smoking around birth may lower the protective effects of breastfeeding on anxiety, depression and neuroticism in adult offspring: a UK biobank study

We aim to explore the combined effects of the smoking and breastfeeding on offspring mental health outcomes. We used data from UK biobank (N = 342,846) to evaluate joint effect of breastfeeding and maternal smoke during pregnancy (MSDP) on seven adult offspring mental health outcomes (self-reported depression, depression score, self-reported anxiety, anxiety score, neuroticism score, self-harm, suicide). We stratified individuals to MSDP group and non-MSDP group as well as breastfeeding group and non-breastfeeding group. Multiple linear regression and logistic regressions analysis were performed between independent variables (MSDP or breastfeeding) and dependent variables separately (seven mental health outcomes) in each stratum. Effect estimates were expressed as β values and OR values. Sex, age, 10 principle components of population structure, smoking, alcohol use, and Townsend deprivation index were examined as covariates. At MSDP grouping level, coefficients (odds ratio [OR]) for association of breastfed as a baby with self-reported anxiety (category variable) were 0.87 (95%CI, (0.82-0.93), P = 1.74 × 10^-5) in the MSDP group and 0.83 (95%CI, (0.79-0.87), P = 2.76 × 10^-17) in the non-MSDP group. At breastfeeding grouping level, OR for association of MSDP and self-reported anxiety were 1.15 (95%CI, (1.10-1.20), P = 5.36 × 10^-11) in breastfeeding group and 1.12(95%CI, (1.06-1.20), P = 2.02 × 10^-4) in non-breastfeeding group. At MSDP grouping level, negatively associations were found for breastfeeding and anxiety score (continuable variable) in MSDP group (-0.04 SD change per SD change in MSDP, 95% CI, (- 0.06, - 0.02), P = 2.42 × 10^-3) and non-MSDP group (-0.06 SD change per SD change in MSDP, 95%CI, (- 0.07, - 0.04), P = 1.70 × 10^-11). At breastfeeding grouping level, positive association was found for MSDP and anxiety score in the breastfeeding group (0.07 SD change per SD change in MSDP, 95%CI, (0.06-0.09), P = 1.49 × 10^-20) and non-breastfeeding group (0.07 SD change per SD change in MSDP, 95%CI, (0.05-0.09), P = 7.19 × 10^-8). Compared with non-MSDP group, the protective effect (reflected by coefficients) of breastfeeding on anxiety in the MSDP decreased. Our preliminary study found MSDP may lower the protective effect of breastfeeding on the adult offspring anxiety, depression and neuroticism, providing useful recommendations for health care service via quitting smoking during pregnancy and encouraging prolonged breastfeeding.

The Use of Cannabis and Its Effects on Postpartum Depression

Cannabis use and depression management have been studied, with a preponderance of exacerbating effects, but there are few studies on postpartum depression (PPD). Depression affects a significant number of women, with a portion of it manifesting as PPD in childbearing women in the United States each year. The pharmacologic management approaches have disadvantages such as side effects, cost-benefit ratio, contraindications, use reluctance, medication adherence, and stigmatization in patients. Anecdotal claims of medical cannabis' therapeutic benefits have led to widespread legalization in several regions, making cannabis and its extracts a possible alternative. Cannabis is widely used during pregnancy and in general. Even though substance use disorders exacerbating depression symptoms have been reported, there are increasing reports and evidence about the therapeutic benefit of dose-dependent cannabis or its extracts in some depression symptoms, such as acute psychosocial stress relief, its purported anxiolytic effect, appetite, and sleep quality, thus stimulating more interest that may be inferred to depression. PPD marijuana use is unclear. This paper reviewed works of literature that claimed cannabis' therapeutic benefit in treating depression and, by extension, PPD. Our findings show the link between cannabis and PPD has not been fully explored. Self-reported studies link marijuana uses to positive mood, anxiety relief, sleep regulation, nausea and vomiting reduction, and appetite stimulation-all PPD symptoms. Others opposed postpartum marijuana use.

Persistent Pregnancy-Related Anxiety Reduces Breastfeeding Exclusiveness and Duration: A Prospective Cohort Study

Objective: Most research has focused on the role of prenatal mental health difficulties on breastfeeding practices, whereas pregnancy-related anxiety (PrA) has been less studied, despite its high prevalence. Identifying new vulnerable subgroups in which the breastfeeding rate remains low is important for health care workers to implement targeted interventions. This study is aimed to explore the association between PrA and breastfeeding practices. Materials and Methods: A total of 3,033 parent-infant dyads from the Ma'anshan Birth Cohort study were included in this research. PrA was assessed by the PrA questionnaire at the second and third trimesters. Breastfeeding practices including the initiation of breastfeeding, delayed lactation, exclusive breastfeeding (EBF), and the duration of breastfeeding were collected at 1, 4, 6, and 12 months postpartum. The associations between PrA and breastfeeding practices were evaluated by multinomial logistic regression and a multivariable Cox proportional hazards model. Results: In total, 9.26% (281/3,033) of participants reported PrA in both trimesters, indicative of persistent PrA. Compared with participants who never suffered from PrA, participants with persistent PrA had a higher risk of giving up EBF at 4 and 6 months postpartum, and a shorter duration of breastfeeding. These results remained the same after excluding participants who gave up EBF due to depression postpartum. Conclusion: Persistent PrA was negatively associated with breastfeeding exclusivity and duration. Addressing PrA might contribute to improved rates of breastfeeding.

Common Complications of Breastfeeding and Lactation: An Overview for Clinicians

Lactation and breastfeeding are core components of reproductive health care and obstetrical providers should be familiar with common complications that may arise in lactating individuals. While many breastfeeding challenges are best addressed by a lactation consultant, there are conditions that fall out of their scope and require care from a clinician. The objective of this chapter is to review common complications of breastfeeding and lactation including inflammatory conditions, disorders of lactogenesis, dermatologic conditions, and persistent pain with lactation.

Feasibility of a Web-Based Intervention to Prevent Perinatal Depression and Promote Human Milk Feeding: Randomized Pilot Trial

BACKGROUND

Mothers who identify as Black or African American are more likely to report depressed moods in late pregnancy and early postpartum and have the lowest rates of human milk feeding compared with all other racial groups in the United States. Internet interventions offer the potential to extend preventative and supportive services as they address key barriers, particularly for those navigating the complex and vulnerable early postpartum period. However, there is limited evidence on the feasibility of such interventions for preventing perinatal mental health disorders and improving human milk feeding outcomes in Black mothers.

OBJECTIVE

This pilot study aimed to assess the feasibility and preliminary findings of a web-based cognitive behavioral therapy-based internet intervention, with and without human milk feeding education and support, to prevent perinatal depression and promote human milk feeding in Black mothers.

METHODS

Participants were Black-identifying individuals between 20 and 28 weeks of pregnancy with human milk feeding intention and mild to moderate depressive symptoms (Patient Health Questionnaire scores 5-14). Participants were randomized to either Sunnyside, a 6-week cognitive behavioral therapy-based web-based intervention, or Sunnyside Plus, which included additional education and support to promote human milk feeding. Assessments occurred at baseline, third trimester (end of antenatal treatment), 6 weeks postpartum (end of postpartum treatment), and 12 weeks postpartum. The primary focus of this randomized pilot trial was the feasibility and preliminary outcomes of mental health and human milk feeding.

RESULTS

A total of 22 tertiary-educated participants were randomized. The mean number of log-ins was 7.3 (SD 5.3) for Sunnyside and 13.8 (SD 10.5) for Sunnyside Plus. Scores of depression and anxiety measures remained below the clinical threshold for referral to treatment in both groups. All the participants initiated human milk feeding (18/18, 100%). Most participants reported at least some human milk feeding at both 6 and 12 weeks postpartum (6/7, 86%; 11/11, 100%, or 10/10, 100%, for Sunnyside and Sunnyside Plus, respectively).

CONCLUSIONS

The results suggest that tertiary-educated Black mothers at risk for perinatal depression and who intended to human milk feed were receptive to and satisfied with a web-based cognitive behavioral therapy-based internet intervention, with and without human milk feeding education and support. Preliminary findings indicate that both Sunnyside and Sunnyside Plus interventions have the potential to affect symptoms of depression, anxiety, and human milk feeding outcomes.

The Effects of Breastfeeding on Maternal Mental Health: A Systematic Review

Background: Breastfeeding has many positive effects on the health of infants and mothers, however, the effect of breastfeeding on maternal mental health is largely unknown. The goal of this systematic review was to (1) synthesize the existing literature on the effects of breastfeeding on maternal mental health, and (2) inform breastfeeding recommendations. Materials and Methods: A literature search was conducted in electronic databases using search terms related to breastfeeding (e.g., breastfeeding, infant feeding practices) and mental health conditions (e.g., mental illness, anxiety, depression), resulting in 1,110 records. After reviewing article titles and abstracts, 339 articles were advanced to full-text review. Fifty-five articles were included in the final analysis. Results: Thirty-six studies reported significant relationships between breastfeeding and maternal mental health outcomes, namely symptoms of postpartum depression and anxiety: 29 found that breastfeeding is associated with fewer mental health symptoms, one found it was associated with more, and six reported a mixed association between breastfeeding and mental health. Five studies found that breastfeeding challenges were associated with a higher risk of negative mental health symptoms. Conclusions: Overall, breastfeeding was associated with improved maternal mental health outcomes. However, with challenges or a discordance between breastfeeding expectations and actual experience, breastfeeding was associated with negative mental health outcomes. Breastfeeding recommendations should be individualized to take this into account. Further research, specifically examining the breastfeeding experiences of women who experienced mental health conditions, is warranted to help clinicians better personalize breastfeeding and mental health counseling.

Analysis of the incidence and influencing factors of postpartum depression and anxiety: A cross-sectional study in Xinjiang from 2018 to 2021

BACKGROUND

Postpartum depression(PPD) and anxiety(PPA) have become the one of major public health threats. However, the research evidence on PPD and PPA in Xinjiang is insufficient. This research reports the incidence of PPD and PPA in the past 4 years, and analyzes the impact of sociodemographic and obstetric factors on postpartum mental health.

METHODS

The selected research objects are parturients who have undergone postpartum health check-ups in a tertiary hospital in Urumqi from January 2018 to September 2021. The study obtained the socio-demographic and obstetric information of the puerpera through general survey questionnaires, and used the PHQ-9 and GAD-7 scales to screen for PPD and PPA. Furthermore, after univariate analysis of related influencing factors of PPD and PPA, multiple binary logistic regression analysis was used to further explore the relationship between PPD and PPA and various influencing factors.

RESULTS

A total of 7,703 parturients were included in this study. The incidence of PPD (PHQ-9 ≥ 10) was 9.7% in 2018, 11.1% in 2019, 13.3% in 2020, and 14.2% in 2021 (χ² = 18.386, P < 0001). The incidence of PPA(GAD-7 ≥ 10) was 8.1% in 2018,8.6% in 2019, 11.4% in 2020, and 9.8% in 2021 (χ² = 16.895, P = 0.001). The six factors that were statistically different after univariate analysis were included in the multivariate binary logistic regression analysis. The final results suggested that women who delivery in 2020 were 1.405 times (95%CI:1.145-1.723) more likely to suffer from depression than those who delivery in 2018 and 1.688 times (95%CI:1.237-2.303) than that in 2021. Compared with puerpera with formal jobs, the incidence of PPD among puerpera who were self-employed (AOR = 1.372,95%CI:1.085-1.735) or unemployed(AOR = 1.348,95%CI:1.137-1.599) was on the rise. Moreover, studies have shown that mixed feeding (AOR = 1.515,95%CI: 1.296-1.772) or artificial feeding (AOR = 1.736,95%CI: 1.299-2.321) 6 weeks postpartum was associated with a higher risk of depression, and puerpera who delivered female infants (AOR = 0.780, 95%CI: 0.626-0.971) were less likely to report depressive symptoms. Simultaneously, for PPA, women who delivered in 2020 were 1.418 times (95%CI: 1.065-1.887) more likely to suffer from anxiety than those who delivered in 2018. Women aged 18-29 years (AOR = 2.070,95%CI:1.229-3.487) were more likely to report PPA than those over the age of 29. Similarly, women who selected cesarean section delivery (AOR = 1.332,95%CI:1.087-1.632) were more likely to have PPA. Mixed feeding (AOR = 1.436,95%CI: (1.193-1.729) ) or artificial feeding (AOR = 1.742,95%CI: 1.243-2.441) at 6 weeks postpartum was associated with a higher risk of anxiety. While puerpera who delivered female infants (AOR = 0.746,95%CI: 0.567-0.982) were less likely to report anxiety symptoms.

CONCLUSION

This study shows that in Xinjiang, the incidence of postpartum depression and anxiety was on the rise from 2018 to 2020, and although there was a slight decline in 2021, it was still higher than in 2019. Simultaneously, the proportion of overweight or obese, cesarean section, and non-breastfeeding women had increased year by year. Factors such as maternal age, occupation, mode of delivery, feeding pattern and neonatal gender may help to identify high-risk patients. Therefore, primary, secondary, and tertiary prevention should be given priority to reduce the incidence of postpartum depression and anxiety in high-risk groups.

Perinatal antidepressant use and breastfeeding outcomes: Findings from the Norwegian Mother, Father and Child Cohort Study

INTRODUCTION

Antidepressant use is common in the perinatal period, but there are concerns that it can negatively impact on breastfeeding outcomes. The aim of this study was to examine the effects of perinatal antidepressant use on breastfeeding initiation and duration.

MATERIAL AND METHODS

This was a retrospective analysis of 80 882 mother-infant dyads in the Norwegian Mother, Father and Child Cohort Study (MoBa). Women were first classified according to self-reported mental disorders and timing of antidepressant use before and/or after gestational week 28 (i.e., early-mid-gestation and/or late-gestation use). We subsequently classified women according to self-reported mental disorders and antidepressant use postpartum and whether antidepressants were continued from late gestation or were new/restarted. Breastfeeding outcomes included breastfeeding initiation as well as predominant or any breastfeeding and abrupt breastfeeding discontinuation until 6 months.

RESULTS

Late-gestation antidepressant use was associated with a reduced likelihood of breastfeeding initiation (adjusted relative risk [aRR] 0.93; 95% confidence interval [CI] 0.90-0.97) but not predominant (aRR 0.96; 95% CI 0.67-1.39) or any (aRR 1.00; 95% CI 0.93-1.07) breastfeeding at 6 months compared with unexposed women with mental disorders. When examined according to postnatal antidepressant use, no differences in predominant (aRR 0.94; 95% CI 0.60-1.48) or any breastfeeding (aRR 0.99; 95% CI 0.91-1.07) at 6 months were evident among women who continued antidepressant use from late gestation into the postpartum period compared with unexposed women with mental disorders. In contrast, new/restarted antidepressant use postpartum was associated with a reduced likelihood of predominant (aRR 0.37; 95% CI 0.22-0.61) and any (aRR 0.49; 95% CI 0.42-0.56) breastfeeding at 6 months, as well as increased risk of abrupt breastfeeding discontinuation (aRR 2.64; 95% CI 2.07-3.37) compared with the unexposed women with mental disorders.

CONCLUSIONS

A complex relation exists between depression, antidepressant use, and breastfeeding outcomes. Antidepressant use in late pregnancy was associated with a reduced likelihood of breastfeeding initiation but not breastfeeding duration or exclusivity. In contrast, initiating or restarting antidepressants postpartum was associated with poorer breastfeeding outcomes. Overall, women taking antidepressants and women with a mental disorder may benefit from additional education and support to improve breastfeeding rates and promote maternal and infant health and wellbeing.

Incidence, antibiotic treatment and outcomes of lactational mastitis: Findings from The Norwegian Mother, Father and Child Cohort Study (MoBa)

BACKGROUND

Mastitis is a common and distressing maternal postpartum condition, but the relationship between mastitis timing and antibiotic treatment and breastfeeding outcomes and postnatal mental health is unclear.

OBJECTIVES

To describe the incidence of mastitis and treatment with antibiotics in first 6 months postpartum, and to investigate the impact of mastitis timing and antibiotic treatment on breastfeeding practices and postnatal mental health.

METHODS

This study is based on 79,985 mother-infant dyads in the Norwegian Mother, Father and Child Cohort Study (MoBa). Women were classified according to self-reported mastitis within first month ('early') or 1-6 months ('later') postpartum and antibiotic treatment. Breastfeeding outcomes included predominant or any breastfeeding and abrupt breastfeeding cessation until 6 months postpartum. Maternal mental health was assessed by self-report at 6 months postpartum.

RESULTS

The incidence of mastitis was 18.8%, with 36.8% reporting treatment with antibiotics. Women reporting early mastitis were less likely to report predominant breastfeeding (adjustedd relative risk [aRR] 0.92, 95% confidence interval [CI] 0.86, 0.99) and any breastfeeding for 6 months (aRR 0.97, 95% CI 0.96, 0.98) than women who did not report mastitis, and more likely to report abrupt breastfeeding cessation (aRR 1.37, 95% CI 1.23, 1.53). Late-onset mastitis was not associated with poorer breastfeeding outcomes. Among women reporting mastitis, the risk of abrupt breastfeeding cessation was higher in those also reporting antibiotic use. Mastitis was associated with an increased risk of mental health problems postpartum which was highest among those reporting no antibiotic use (aRR 1.29, 95% CI 1.18, 1.41), in contrast to those also reporting antibiotic use (aRR 1.08, 95% CI 0.96, 1.22).

CONCLUSIONS

Lactational mastitis and its associated treatment with antibiotics are common. Early (<1 month postpartum) mastitis appears to be a modest risk factor for suboptimal breastfeeding outcomes. In addition, mastitis is associated with poorer mental health.

Maternal Psychological Distress and Lactation and Breastfeeding Outcomes: a Narrative Review

PURPOSE

Despite recommendations from the World Health Organization and the American Academy of Pediatrics to exclusively breastfeed infants for their first 6 months of life, 75% of women do not meet exclusive breastfeeding guidelines, and 60% do not meet their own breastfeeding goals. Numerous observational studies have linked maternal psychological distress (eg, perceived stress, anxiety, and depression) with nonoptimal breastfeeding outcomes, such as decreased proportion and duration of exclusive breastfeeding. The physiological mechanisms underlying these associations, however, remain unclear.

METHODS

For this narrative review, we evaluated the evidence of relationships between maternal psychological distress and lactation and breastfeeding outcomes in pregnancy and post partum and the possible physiological mechanisms that facilitate these relationships. We searched PubMed using the following terms: stress, anxiety, depression, breastfeeding, and lactation. Additional search by hand was conducted to ensure a thorough review of the literature.

FINDINGS

Among the studies examined, methods used to assess maternal psychological distress were not uniform, with some studies examining perceived distress via a variety of validated tools and others measuring biological measures of distress, such as cortisol. Evidence supports a role for psychological distress in multiple breastfeeding outcomes, including delayed secretory activation and decreased duration of exclusive breastfeeding. One physiological mechanism proposed to explain these relationships is that psychological distress may impair the release of oxytocin, a hormone that plays a critical role in milk ejection during lactation. Continued impairment of milk ejection may lead to decreased milk production because of incomplete emptying of the breast during each feed. Maternal distress may also yield elevated levels of serum cortisol and decreased insulin sensitivity, which are associated with decreased milk production. The relationship between psychological distress and breastfeeding is likely to be bidirectional, however, in that breastfeeding appears to reduce maternal distress, again possibly via effects on the pleasure or reward pathway and calming effects of oxytocin on the mother. This finding suggests that interventions to support lactation and breastfeeding goals in women who score high on measures of psychological distress would be beneficial for both maternal and infant well-being.

IMPLICATIONS

Evidence to date suggests that maternal psychological distress may impair lactation and breastfeeding outcomes, but stronger study designs and rigorous assessment methods are needed. A better understanding of the physiological mechanisms leading to impaired lactation may assist in the development of early interventions for mothers experiencing distress. In addition, stress-reducing programs and policies should be investigated for their potential to improve breastfeeding outcomes.

Lactation is not required for maintaining maternal care and active coping responses in chronically stressed postpartum rats: Interactions between nursing demand and chronic variable stress

Women who do not breastfeed or discontinue breastfeeding early are more likely to develop postpartum depression (PPD) and stress is a significant risk factor for depression, including PPD. Using a rat model, we investigated whether the absence of nursing would increase the susceptibility to chronic stress-related behavioral and neural changes during the postpartum period. Adult female rats underwent thelectomy (thel; removal of teats), sham surgery, or no surgery (control) and were paired with males for breeding. All litters were rotated twice daily until postpartum day (PD) 26. Sham rats served as surrogates for thel litters, yielding a higher nursing demand for sham rats. Concurrently, rats received either no stress or chronic variable stress until PD 25. Rats were observed for maternal behaviors and tested in a series of tasks including open field, sucrose preference, and forced swim. We used immunohistochemistry (IHC) for doublecortin (DCX; to label immature neurons) or for mineralocorticoid receptor (MR). Contrary to our expectations, non-nursing thel rats were resistant to the effects of stress in all dependent measures. Our data indicate that even in chronic adverse conditions, nursing is not required for maintaining stable care to offspring or active coping responses in an acutely stressful task. We discuss the possible role of offspring contact and consider future directions for biomedical and clinical research. In rats with high nursing demand, however, chronic stress increased immobility, hippocampal neurogenesis, and MR expression (largely in opposition to the effects of stress in rats with typical nursing demand). We discuss these patterns in the context of energetics and allostatic load. This research highlights the complexity in relationships between stress, nursing, and neurobehavioral outcomes in the postpartum period and underscores the need for additional biomedical and clinical research geared toward optimizing treatments and interventions for women with PPD, regardless of breastfeeding status. SIGNIFICANCE STATEMENT: The goal of this research was to determine how the absence of nursing and higher nursing demand impact stress-coping behaviors and neural changes associated with chronic stress in order to disentangle the complex interplay of factors that contribute to psychological illness during the postpartum period.

Exclusive Breastfeeding Moderates the Association Between Prenatal and Postpartum Depression

BACKGROUND

Exclusive breastfeeding has a wide range of benefits for maternal health. However, the benefit of exclusive breastfeeding for maternal mental health needs to be further explored.

RESEARCH AIM

To determine the moderating role of exclusive breastfeeding at 3 months on the association between prenatal and postpartum depression.

METHODS

This study had a prospective, longitudinal, and comparative design with two groups and three assessment waves. The sample comprised 334 participants (70 depressed and 264 non-depressed) recruited at public health services in northern Portugal. Participants completed a measure of depression symptoms between the second and the third trimester of pregnancy and between 3 and 6 months, and a measure of breastfeeding status at 3 months.

RESULTS

Exclusive breastfeeding at 3 months moderated the association between prenatal and postpartum depression. Participants with prenatal depression who were exclusively breastfeeding at 3 months showed fewer symptoms of depression and lower rates of depression between 3 and 6 months postpartum, compared to participants with prenatal depression who were not exclusively breastfeeding. Participants without prenatal depression who were exclusively breastfeeding at 3 months showed similar depression symptoms and similar rates of depression between 3 and 6 months postpartum, compared to participants without prenatal depression who were not exclusively breastfeeding.

CONCLUSION

Exclusive breastfeeding has a potential protective influence on postpartum depression among women with prenatal depression. Public health policies targeting women with prenatal depression should be implemented and include practices to promote and support exclusive breastfeeding in order to enhance women's exclusive breastfeeding and mental health.
