Breastfeeding is universally recognized for its extensive health benefits for both infants and mothers. However, for some women, the experience of breastfeeding can be complicated by intense negative emotional and physical reactions, including phenomena such as dysphoric milk ejection reflex and breastfeeding aversion/agitation. This review explores the neuroendocrine underpinnings of these conditions, emphasizing the interplay between oxytocin, prolactin, and dopamine. Oxytocin, traditionally viewed as a hormone promoting bonding and emotional regulation, can paradoxically provoke a stress response in vulnerable individuals. Prolactin, a key hormone for lactation and maternal behaviors, is implicated in stress resilience and mood regulation, but its dysregulation may contribute to depressive states. Dopamine, critical for reward processing and emotional stability, may underlie the acute emotional dysregulation seen in dysphoric milk ejection reflex. Together, disturbances in these neurohormonal systems may explain the aversive emotional experiences during breastfeeding. An improved understanding of these mechanisms offers critical insights into maternal mental health during lactation and underscores the importance of supportive clinical approaches for affected women.

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

Preterm birth is a significant global health issue affecting millions of infants each year, with potential implications for their developmental outcomes. This study investigated the impact of preterm birth on maternal mood states during the early postpartum period and its subsequent effects on mother–infant bonding. Mothers of 90 preterm infants were involved in the assessment of maternal mood states, examined with the Profile of Mood States (POMS) questionnaire and the evaluation of mother–infant bonding, carried out through the Postpartum Bonding Questionnaire (PBQ). Contrary to expectations, there was no significant correlation between preterm birth characteristics and maternal mood states. On the other hand, significant correlations emerged between specific maternal mood states and the quality of mother–child bonding. More specifically, regression analyses showed that feelings of tension, anger, and confusion experienced by the mother tend to negatively affect the quality of her bond with her child. These findings emphasize the crucial role of maternal mental well-being in shaping the mother–infant relationship in the early postpartum period. The study highlights the importance of identifying and addressing maternal mood disorders to promote positive mother–infant bonding and child development, further underlining the need for comprehensive support and interventions for mothers of preterm infants.

Numerous factors not consistently identified in pregnancy are linked with decreased breastfeeding exclusivity and durations. These factors may be considered in three domains: the anatomical, metabolic, and psychosocial domains. As fundamental research into lactation has increased, it is now often possible to identify or speculate the mechanisms by which these factors potentially reduce milk production. The first domain describes the anatomical characteristics of the breast, including intrinsic factors such as hypoplasia (underdevelopment), which may have a genetic component and can be masked by breast augmentation surgery. Hypoplasia has long been associated with the inability to make a full milk production that satisfyies the infant’s needs, although it is not possible to predict a woman’s 24-h milk production so that appropriate complementary feeds can be advised. Extrinsic causes such as breast reduction surgery impact the volume of glandular tissue, thereby reducing the synthetic capacity of the breast. Whereas nipple piercings may damage milk ducts, obstructing milk flow from the breast and thereby reducing milk supply via the autocrine pathway. Various maternal metabolic disorders (intrinsic) comprise the second domain, which includes conditions such as gestational diabetes mellitus, type 1 and 2 diabetes, polycystic ovarian syndrome (often undiagnosed), and hypothyroidism. The aberrant levels of hormones associated with these disorders, such as insulin, are also implicated in breast development, raising the possibility of reduced mammary growth in pregnancy and, consequently, milk production. Much more research is needed in this area, not only to understand mechanisms by which lactation is impacted but also to identify the women at risk of reduced lactation capacity. The third and final domain includes psychosocial issues such as short intended breastfeeding durations, a lack of breastfeeding support, and maternal anxiety and depression. With respect to anxiety and depression, their association with reduced breastfeeding is likely multifaceted, encompassing mood and the potential biochemical changes associated with these states, such as lower levels of circulating oxytocin and higher cortisol levels. Possessing a knowledge of the negative impacts of the intrinsic and extrinsic factors within the maternal anatomical, metabolic, and psychosocial domains provides the impetus for antenatal lactation screening. The antenatal identification of risk factors enables anticipatory guidance and education during pregnancy, as well as early postpartum intervention should breastfeeding issues occur. Full article

Background: The post-delivery period could be characterized by psychological distress (e.g., anxiety, sadness, and irritability), leading to postpartum depression (PPD). Objective: The present clinical study assesses the effect of probiotic supplementation containing Limosilactobacillus reuteri PBS072 and Bifidobacterium breve BB077 (4 × 10⁹ CFU/day) on the mother’s mood and breastfeeding quality during the first trimester after delivery. Methods: A Randomized, Double-Blind, Controlled (RDBPC) trial was carried out on 200 healthy new mothers divided into an active group taking a supplement containing Limosilactobacillus reuteri PBS072 and Bifidobacterium breve BB077 (4 × 10⁹ CFU/day) plus multivitamins and a control group (multivitamin complex only) for 90 days. Symptoms related to maternal depression and breastfeeding quality were evaluated at days 45 and 90 using the Edinburgh Postnatal Depression Scale (EPDS) and the Breastfeeding Self-Efficacy Scale—Short Form (BSES-SF). Results: At days 45 and 90, the probiotic treatment significantly ameliorated the mothers’ mood compared to the control treatment (p < 0.001). Likewise, the breastfeeding quality and the baby’s cries significantly improved in the probiotic group (p < 0.001). Conclusions: Microbiota alterations could influence a post-delivery woman’s mental state. According to our results, L. reuteri PBS072 and B. breve BB077 are potential candidates that are able to improve stress resilience in the postpartum period. Full article

The developing infant gut microbiome is highly sensitive to environmental exposures, enabling its evolution into an organ that supports the immune system, confers protection from infection, and facilitates optimal gut and central nervous system function. In this study, we focus on the impact of maternal psychosocial stress on the infant gut microbiome. Forty-seven mother–infant dyads were recruited at the HEAL Africa Hospital in Goma, Democratic Republic of Congo. Extensive medical, demographic, and psychosocial stress data were collected at birth, and infant stool samples were collected at six weeks, three months, and six months. A composite maternal psychosocial stress score was created, based on eight questionnaires to capture a diverse range of stress exposures. Full-length 16S rRNA gene sequences were generated. Infants of mothers with high composite stress scores showed lower levels of gut microbiome beta diversity at six weeks and three months, as well as higher levels of alpha diversity at six months compared to infants of low stress mothers. Longitudinal analyses showed that infants of high stress mothers had lower levels of health-promoting Lactobacillus gasseri and Bifidobacterium pseudocatenulatum at six weeks compared to infants of low stress mothers, but the differences largely disappeared by three to six months. Previous research has shown that L. gasseri can be used as a probiotic to reduce inflammation, stress, and fatigue, as well as to improve mental state, while B. pseudocatenulatum is important in modulating the gut–brain axis in early development and in preventing mood disorders. Our finding of reduced levels of these health-promoting bacteria in infants of high stress mothers suggests that the infant gut microbiome may help mediate the effect of maternal stress on infant health and development.

The progress in fetal cardiology allows for the early diagnosis of congenital heart defects, but there is still a lack of data on the psychological situation of parents expecting a child with a congenital heart defect. In this cross-sectional study, 77 parents (45 women and 32 men) expecting a child with a heart defect were interviewed with different questionnaires. The standardized Hospital Anxiety and Depression Scale (HADS) questionnaire was used to assess the psychological state of the parents. Various statistical procedures were performed to determine the prevalence, risk factors, and predictors of anxiety and depression. The prevalence for prenatal anxiety was 11.8% and for depressed mood 6.6%, whereas the postnatal prevalence was 25% for anxiety and 16.7% for depressed mood. The mother is influential in protecting against depression as a contact person (p = 0.035). Women were more affected by anxiety and depression than men (p = 0.036). A significant and positive correlation was observed between anxiety and depression before birth (ρ = 0.649, p < 0.001) and after birth (ρ = 0.808, p < 0.001). The level of education correlated negatively with depression (p = 0.016) and anxiety (p = 0.017) before birth. Significantly higher anxiety and depression scores were not observed among health and social workers (p = 0.084), first-time mothers (p = 0.190), and parents whose pregnancies were due to medical assistance (p = 0.051). Close collaboration between maternal-fetal care units, pediatric cardiologists and psychiatric/psychosomatic disciplines is a possible strategy to reduce stress in parents. Therefore, an expert team of professionals, educating with understandable terms and sufficient knowledge about fetal heart disease in parenting counseling, is required. The support of affected parents can positively impact the treatment of the child and should be integrated into the daily routine of the clinic. Full article

Background: Women in the postpartum period may be particularly vulnerable to the psychological effects of the COVID-19 pandemic. The aim of our study was to evaluate the impact of the coronavirus pandemic on postpartum depression and anxiety levels and the role of the fear of COVID-19 in its development. Methods: Women who delivered at the Bissaya Barreto Maternity Hospital, between 16 March and 16 June 2020 (Group 1: Birth in COVID-19 period, n = 207), recruited in the postpartum period, filled in a set of self-reported validated questionnaires: Perinatal Depression Screening Scale, Perinatal Anxiety Screening Scale, Profile of Mood States, Perseverative Thinking Questionnaire, Dysfunctional Beliefs Towards Maternity Scale, and the Fear of COVID-19 Scale. Levels of depressive and anxious symptomatology, negative affect, negative repetitive thinking, and the dysfunctional beliefs towards motherhood of these women were compared with data from samples of previous studies that included women whose delivery had occurred at the same Maternity Hospital before the COVID-19 pandemic period (Group 2: Birth before the COVID-19 period, n = 212). Results: Based on the cutoff points of the screening scales, the prevalence of clinically relevant depressive and anxious symptoms in Group 1 was 40.1% and 36.2%, respectively. Women in Group 1 had significantly higher levels of anxious and depressive symptoms, negative affect, negative repetitive thinking, and dysfunctional beliefs towards motherhood than women in Group 2 (p < 0.05). Fear of COVID-19 in the postpartum period was a predictor of depressive (ß = 0.262) and anxious (ß = 0.371) symptoms, explaining 6.9% and 13.7% of their variability, respectively (p < 0.001). Conclusion: During the COVID-19 pandemic, women in the postpartum period present greater depressive and anxious symptomatology, as well as increased risk factors. Full article

Background. Depression is a common mood disorder during pregnancy impacting one in every seven women. Children exposed to prenatal depression are more likely to be born at a low birth weight and develop chronic diseases later in life. A proposed hypothesis for this relationship between early exposure to adversity and poor outcomes is accelerated aging. Telomere length has been used as a biomarker of cellular aging. We used high-resolution telomere length analysis to examine the relationship between placental telomere length distributions and maternal mood symptoms in pregnancy. Methods. This study utilised samples from the longitudinal Grown in Wales (GiW) study. Women participating in this study were recruited at their presurgical appointment prior to a term elective caesarean section (ELCS). Women completed the Edinburgh Postnatal Depression Scale (EPDS) and trait subscale of the State-Trait Anxiety Inventory (STAI). Telomere length distributions were generated using single telomere length analysis (STELA) in 109 term placenta (37–42 weeks). Multiple linear regression was performed to examine the relationship between maternally reported symptoms of depression and anxiety at term and mean placental telomere length. Results: Prenatal depression symptoms were significantly negatively associated with XpYp telomere length in female placenta (B = −0.098, p = 0.026, 95% CI −0.184, −0.012). There was no association between maternal depression symptoms and telomere length in male placenta (B = 0.022, p = 0.586, 95% CI −0.059, 0.103). There was no association with anxiety symptoms and telomere length for either sex. Conclusion: Maternal prenatal depression is associated with sex-specific differences in term placental telomeres. Telomere shortening in female placenta may indicate accelerated placental aging. Full article

This study examined the effect of a brief psycho-educational program, Time Together, on maternal self-efficacy, mother-infant bonding, and mood/anxiety for community-based mothers. This program centered on maternal voice, timing of interplay, and recognition of infant cues. A convergent parallel mixed-methods design included quantitative measures: the Karitane Parenting Confidence Scale, the Mother-Infant Bonding Scale, Edinburgh Postnatal Depression Scale and State & Trait Anxiety Inventory, and a sequential qualitative analysis to elaborate on the quantitative findings. Significant changes on the Karitane Parenting Confidence Scale were found. Qualitative analysis of the participant interviews and reflective diaries from the two weeks following the psycho-educational program confirmed that participation enhanced mothers’ ability to understand their infant, to soothe their infant when distressed, to play and to establish an effective bedtime routine. This feasibility study indicated that this is a promising approach to improve early mother-infant interaction and maternal self-efficacy. Full article

Mothers in the United States (U.S.) who are of non-dominant culture and socioeconomically disadvantaged experience depression during postpartum at a rate 3 to 4 times higher than mothers in the general population, but these mothers are least likely to receive services for improving mood. Little research has focused on recruiting these mothers into clinical intervention trials. The purpose of this article is to report on a study that provided a unique context within which to view the differential success of three referral approaches (i.e., community agency staff referral, research staff referral, and maternal self-referral). It also enabled a preliminary examination of whether the different strategies yielded samples that differed with regard to risk factors for adverse maternal and child outcomes. The examination took place within a clinical trial of a mobile intervention for improving maternal mood and increasing parent practices that promote infant social communication development. The sample was recruited within the urban core of a large southern city in the U.S. and was comprised primarily of mothers of non-dominant culture, who were experiencing severe socioeconomic disadvantage. Results showed that mothers self-referred at more than 3.5 times the rate that they were referred by either community agency staff or research staff. Moreover, compared to women referred by research staff, women who self-referred and those who were referred by community gatekeepers were as likely to eventually consent to study participation and initiate the intervention. Results are discussed with regard to implications for optimizing referral into clinical intervention trials. Full article

There is inconsistent evidence that healthy dietary interventions can effectively mitigate the risk of adverse outcomes associated with elevated insulin resistance in pregnancy, suggesting that other moderating factors may be at play. Maternal psychological state is an important factor to consider in this regard, because stress/mood state can directly influence glycemia and a bidirectional relationship may exist between nutrition and psychological state. The objective of this study was to examine the interaction between maternal negative affect and diet quality on third trimester insulin resistance. We conducted a prospective longitudinal study of N = 203 women with assessments in early and mid-pregnancy, which included an ecological momentary assessment of maternal psychological state, from which a negative affect score (NAS) was derived, and 24-h dietary recalls, from which the Mediterranean Diet Score (MDS) was computed. The homeostasis model assessment of insulin resistance (HOMA-IR) was computed from third trimester fasting plasma glucose and insulin values. Early pregnancy MDS was inversely associated with the HOMA-IR, but this did not maintain significance after adjusting for covariates. There was a significant effect of the mid-pregnancy MDS*NAS interaction term with the HOMA-IR in the adjusted model, such that a higher negative affect was found to override the beneficial effects of a Mediterranean diet on insulin resistance. These results highlight the need to consider nutrition and affective state concurrently in the context of gestational insulin resistance. Full article

Evidence from human studies indicates that maternal metabolic state and malnutrition dramatically influence the risk for developing psychiatric complications in later adulthood. In this regard, the central role of polyunsaturated fatty acids (PUFAs), and particularly n-3 PUFAs, is emerging considering that epidemiological evidences have established a negative correlation between n-3 PUFA consumption and development of mood disorders. These findings were supported by clinical studies indicating that low content of n-3 PUFAs in diet is linked to an increased susceptibility to psychiatric disorders. PUFAs regulate membrane fluidity and exert their central action by modulating synaptogenesis and neurotrophic factor expression, neurogenesis, and neurotransmission. Moreover, they are precursors of molecules implicated in modulating immune and inflammatory processes in the brain. Importantly, their tissue concentrations are closely related to diet intake, especially to maternal consumption during embryonal life, considering that their synthesis from essential precursors has been shown to be inefficient in mammals. The scope of this review is to highlight the possible mechanisms of PUFA functions in the brain during pre- and post-natal period and to evaluate their role in the pathogenesis of psychiatric diseases.
