The significance of breastfeeding practices on postpartum depression risk

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

BACKGROUND

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

AIM

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

METHODS

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

RESULTS

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

CONCLUSION

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

The Mental Health Effects and Experiences of Breastfeeding Decision-Making Among Postpartum Women Living with HIV

Prior to January 2023, women living with HIV (WLWH) in the United States (US) were discouraged from breastfeeding due to the potential risk of mother-to-child HIV transmission through breastfeeding. Lack of breastfeeding decision-making and experience among WLWH may negatively affect maternal mental health. We implemented a quality improvement initiative to screen WLWH for postpartum depression (PPD), evaluate their attitudes toward breastfeeding, and assess their experience with breastfeeding decision-making. We collected quantitative data from WLWH using a voluntary, self-administered 6-item breastfeeding decision-making and experience survey (administered 1 month postpartum) and a 10-item Edinburgh Postnatal Depression Scale (EPDS, negative = 0-9; administered 1 and 4 months postpartum) tool. We conducted descriptive statistics and cross tabulation analysis. We analyzed 106 WLWH (93.4% non-Hispanic Black/African American; mean age 33.1 years; 82.1% HIV RNA < 200 copies/mL). One in five (19.1%) WLWH had a positive baseline EPDS screen, with the mean EPDS scores decreasing from 5.3 ± 5.4 (baseline) to 4.6 ± 4.8 (follow-up). Among 55 WLWH who provided baseline and follow-up EPDS scores, only 3/13 with a positive baseline EPDS screen had resolved depressive symptoms at follow-up. Over one-third (37.7%) of WLWH indicated feeling "sadness" when asked whether lack of breastfeeding negatively affected their feelings or emotions. Over half of WLWH (51.9%) were aware of the US breastfeeding recommendations, but the majority (60.4%) had never discussed breastfeeding options with a medical provider. Improved provider-patient discussions on infant feeding options among WLWH is needed to increase awareness of breastfeeding choices and promote informed, autonomous breastfeeding decision-making among WLWH.

Effect of Breastfeeding Education Program and Nurse-led Breastfeeding Online Counseling System (BMUM) for Mothers: A Randomized Controlled Study

BACKGROUND

Breastfeeding is very important for maternal and infant health. With first pregnancies, many pregnant people face obstacles to achieving their breastfeeding goals.

RESEARCH AIMS

We aimed to investigate the outcomes of a breastfeeding education program and nurse-led online breastfeeding counseling system (BMUM) on breastfeeding self-efficacy, attitudes about breastfeeding, breastfeeding problems, breastfeeding frequencies and postpartum depression.

METHODS

This study was a randomized controlled trial. Participants were randomly assigned to the intervention group (n = 36), or control group (n = 36). Assessments were conducted during pregnancy, between 32- and 37-weeks gestation, and on postpartum Day 1, Week 1, Week 3, and 6 months.

RESULTS

The means of the Breastfeeding Self-Efficacy-Short Form scores, and the Infant Feeding Attitude Scale (IIFAS) scores were similar between the groups at the first assessment (p = 0.733). IIFAS scores in the intervention group were significantly higher in the follow-up measurements on postpartum Day 1, Week 1, Week 3, and 6 months compared to scores in the control group (p = 0.006; p = 0.000; p = 0.002; p = 0.001) Edinburgh Postpartum Depression Scale (EPDS) scores were similar between the two groups at 1 week (p = 0.678). EPDS scores were significantly higher in the control group on Day 1 and at 3 and 6 months postpartum (p = 0.000; p = 0.038; p = 0.042). There was no statistically significant difference in breastfeeding problems between the two groups (p > 0.05 across breastfeeding problems examined). The mean values of breastfeeding frequency were similar between groups on Day 1, and significantly higher in the intervention group on follow-up measurements.

CONCLUSION

The results of this intervention appear to promote positive attitudes toward breastfeeding and decrease feelings of postpartum depression. However, further randomized controlled trials are needed to support our outcomes.

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.

Evaluation of the Impact of a Midwife-Led Breastfeeding Group Intervention on Prevention of Postpartum Depression: A Multicentre Randomised Clinical Trial

Postpartum depression is a significant health issue affecting both mothers and newborns during the postpartum period. Group support interventions during this period have proven effective in helping women cope with depression and improving breastfeeding rates. This study aimed to assess the effectiveness of a midwife-led breastfeeding support group intervention on breastfeeding rates, postpartum depression and general self-efficacy. This was a multicentric cluster randomised controlled trial with control and intervention groups and was not blinded. It was conducted in Andalusia (southern Spain) from October 2021 to May 2023. A total of 382 women participated in the study. The results showed a significant difference in exclusive breastfeeding rates at 4 months postpartum between the groups (control 50% vs. intervention 69.9%; p < 0.001). Additionally, there was a lower mean score on the Edinburgh Postnatal Depression Scale in the intervention group (12.49 ± 3.6 vs. 13.39 ± 4.0; p = 0.044). Similarly, higher scores of general self-efficacy were observed among breastfeeding women at 2 and 4 months postpartum (77.73 ± 14.81; p = 0.002 and 76.46 ± 15.26; p < 0.001, respectively). In conclusion, midwife-led breastfeeding support groups enhanced self-efficacy, prolonged breastfeeding and reduced postpartum depression 4 months after giving birth.

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

PURPOSE OF REVIEW

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

RECENT FINDINGS

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

The Ethics of Ancient Lactation and the Cult of the Perfect Breastfeeding Mother

Breastfeeding is a key issue found in ancient sources that resonates with public debates today, affecting women in different parts of the world and of all social classes. The aim of this research was to identify breastfeeding narratives in ancient medical and philosophical texts from the 1st to the 6th century CE that address ethical issues in the medical management and social perception of new mothers. We examined 15 literary sources and one funerary inscription on lactation and critically evaluated the ancient idea of the perfect breastfeeding mother versus the non-breastfeeding mother. We then discussed our historical data in terms of objectivity and significance in relation to contemporary attitudes towards motherhood and lactation, e.g., (1) the cult of the perfect, breastfeeding mother in contemporary lactation education and (2) the onset of conditions which may affect normal breastfeeding, such as dysphoric milk ejection reflex (D-MER), breastfeeding aversion response (BAR) or post-partum depression. The analysis of the results showed that in both ancient and contemporary postnatal health care: (1) good mothering is associated with breastfeeding and (2) alternative feeding methods are acknowledged, but never as the best, natural option. Finally, our analysis shows that public health policies on breastfeeding and mothers' own knowledge of their bodies are contested between nursing theories, social expectations and economic factors.

Factors associated with postpartum depressive symptoms among women who conceived with infertility treatment

Infertility treatment experiences may accumulate and influence postpartum psychological well-being among women with infertility. However, the association between infertility treatment experiences and postpartum depressive symptoms remained unclear. This cross-sectional survey aimed to describe depressive symptom scores of 180 women, who conceived while undergoing infertility treatment, at 2-6 months after childbirth, and to explore factors, including infertility history and treatment experiences, associated with postpartum depressive symptoms. Data were collected via telephone interviews and patient record reviews. Postpartum depressive symptoms were measured using the Edinburgh Postnatal Depression Scale, with a cutoff score of 10. The prevalence of postpartum depressive symptoms was 34.4 %. Higher perceived stress levels after childbirth than before undergoing infertility treatment, a duration of infertility diagnosis longer than three years, maternal age >35 years, pregnancy conceived through in vitro fertilization (IVF), and experiencing all three lines of infertility treatment, namely ovarian stimulation, intrauterine insemination, and IVF, were associated with a higher risk of postpartum depressive symptoms. Breastfeeding, social support, and baby sex in line with stated preference were negatively associated with postpartum depressive symptoms. There were no significant interactions between the variables. The women's infertility history and treatment experiences were found to have influenced their postpartum depressive symptoms, especially among women who had a long duration of infertility, conceived through IVF, and had received all lines of infertility treatment.

Association between exclusive breastfeeding and postpartum post-traumatic stress disorder

BACKGROUND

Research on the association between breastfeeding and postpartum post-traumatic stress disorder (PTSD) is sparse. This study aimed to examine the association between exclusive breastfeeding up to 42 days after childbirth and postpartum PTSD.

METHODS

An epidemiologic study was conducted in a tertiary hospital in China between October 2019 and October 2020. Eligible mothers were recruited at 3 days after childbirth and assessed using the Post-Traumatic Stress Disorder Checklist - Civilian version (PCL-C) for PTSD at 42 days postpartum. The independent association between exclusive breastfeeding up to 42 days after childbirth and postpartum PTSD was estimated using log-binomial regression models, after adjusting for potential confounders.

RESULTS

Ninety-two of 759 (12.1%) mothers developed postpartum PTSD within 42 days after childbirth. Compared with partially breastfeeding mothers, exclusively breastfeeding mothers had lower risks of postpartum PTSD (relative risk [RR] 0.28; 95% confidence interval [CI] 0.13, 0.59), re-experience (RR 0.48; 95% CI 0.30, 0.76), avoidance (RR 0.55; 95% CI 0.32, 0.97), and hyperarousal (RR 0.52; 95% CI 0.34, 0.78). After adjustment for family support, parity, mode of delivery, perceived birth trauma, early contact / suckling, and rooming-in, associations between exclusive breastfeeding and postpartum PTSD remained significant: the overall PTSD adjusted relative risk [aRR] was 0.31; (95% CI 0.15, 0.66), with a re-experience aRR of 0.48; (95% CI 0.30, 0.77) and hyperarousal aRR of 0.56; (95% CI 0.37, 0.85).

CONCLUSION

Exclusive breastfeeding up to 42 days after childbirth was associated with reduced risk of postpartum PTSD. While the potential for reverse causation cannot be ruled out, strategies to improve rates of exclusive breastfeeding through teaching, counselling, and support may benefit mothers and their infants by reducing the risk of postpartum PTSD.

Postpartum Depressive Symptoms and Their Selected Psychological Predictors in Breast-, Mixed and Formula-Feeding Mothers

BACKGROUND

Although breastfeeding is recommended by WHO and professionals as the most beneficial for newborn babies, many women find it challenging. Previous research yielded ambiguous results concerning the role of breastfeeding in the development of postpartum depression. The study aimed to identify the best predictors of depressive symptoms for each of these feeding method.

METHODS

The participants were 151 women (mean age 29.4 yrs; SD = 4.5) who gave birth within the last 6 months and included 82 women classified as breastfeeding, 38 classified as mixed-feeding (breast and bottle), and 31 as formula-feeding. The study had a cross-sectional design using a web-based survey for data collection. The following measures were administered: The Edinburgh Postnatal Depression Scale; Sense of Stress Questionnaire; The Postpartum Bonding Questionnaire; Parenting Sense of Competence Scale; Infant Feeding Questionnaire.

RESULTS

Women in study groups differed in stress, bonding difficulties, and beliefs related to feeding practices and infancy. There were no significant differences in the severity of depressive symptoms, but all mean EPDS scores were above 12. Maternal satisfaction, intrapsychic stress, and concerns about feeding on a schedule were the best predictors of EPDS scores for breastfeeding women. For mixed-feeding - emotional tension, concern about infant's hunger, overeating, and awareness of infant's hunger and satiety cues; while for the formula-feeding group, predictors included emotional tension, bonding difficulties, and such maternal feeding practices and beliefs as concern about undereating, awareness of infant's hunger and satiety cues, concerns about feeding on a schedule and social interaction with the infant during feeding.

CONCLUSION

Differences in predictors of postpartum depression for study groups suggest that breastfeeding itself may not be a risk for postpartum depression. However, the specificity of maternal experiences with the various types of feeding is related to difficulties promoting postpartum depression. Providing emotional and educational support appropriate for different types of feeding may be an essential protective factor for postnatal depression.
