Exclusive breastfeeding to 6 months postpartum has been related to breastfeeding self-efficacy in diverse populations. Globally, this is measured using the Breastfeeding Self-Efficacy Scale–Short Form (BSES-SF).

To evaluate the psychometric properties of the BSES-SF among women in Malawi; and to examine the relationship between breastfeeding self-efficacy and demographic and health factors.

The study design was a prospective, cross-sectional survey with a 2 week follow-up reliability check. Postpartum women (N = 180) were recruited at a maternity hospital in Lilongwe, Malawi. In addition to the BSES-SF, the World Health Organization's Quality of Life Scale (QoL) was also administered. Furthermore, confirmatory factor analysis, Cronbach's alpha, and Pearson's correlations were used to examine the construct validity, reliability, test-retest reliability, and convergent validity.

The confirmatory factor analysis supported a unidimensional structure of the Malawian version of the 12-item BSES-SF. Cronbach's alpha and the intra-class correlation coefficient were 0.79 and 0.75, respectively. BSES-SF scores had significant correlation with QoL domains (physical QoL: r = 0.31, p < .001; and environmental QoL: r = 0.22, p < .01). Participants’ age, parity, and mode of delivery were positively correlated with breastfeeding self-efficacy scores.

The findings of our study confirmed that the 12-item BSES-SF is a reliable and valid scale for assessing women’s breastfeeding self-efficacy in Malawi.

Research gaps exist with regard to paternal attitudes towards breastfeeding and the association between fathers’ attitudes and the type of breastfeeding.

To analyze the psychometric properties of the Spanish version of the Iowa Infant Feeding Attitude Scale in fathers, and (2) to examine the association between fathers’ attitudes and type of breastfeeding.

We used a cross-sectional study design to analyze the scale’s psychometric properties and performance.

A total of 639 fathers participated in the study. The mean age was 35.83 years (SD = 4.65) and 67.3% (n = 430) were married or in a civil partnership. We observed an adequate fit in the confirmatory factor analysis: TLI = 0.96, CFI = 0.97 and RMSEA = 0.05. The overall internal consistency was 0.76. Between 1–6 months, 48% (n = 307) of participants’ babies were exclusively breastfed, 35.2% (n = 225) were partially breastfed, and 16.7% (n = 107) were exclusively formula fed. Statistically significant differences were shown in attitudes towards breastfeeding, depending on the type of breastfeeding, between 1 and 6 months (F = 54.67; p < .001). Fathers who reported that their baby had been exclusively breastfed scored higher on attitudes towards breastfeeding. Statistically significant differences were also found between partial breastfeeding and formula feeding.

The Spanish version of the Iowa Infant Feeding Attitude Scale is a valid and reliable instrument for measuring paternal attitudes towards breastfeeding.

Pregnant and recently pregnant people have lower vaccination rates against SARS-CoV-2 than the general population, despite increased risk of adverse outcomes from infection. Little is known about vaccine hesitancy in this population.

To characterize SARS-CoV-2 and other vaccine attitudes of lactating people who accepted the SARS-CoV-2 vaccine, describing their vaccine experiences to further contextualize their beliefs.

A prospective cross-sectional online survey design was used. We administered the survey to 100 lactating people in Pennsylvania from April to August 2021, upon enrollment into a longitudinal study investigating SARS-CoV-2 vaccine antibodies in human milk. This survey assessed SARS-CoV-2 vaccine attitudes, vaccine counseling from providers, and vaccine decision making. Associations between vaccination timing and beliefs were analyzed by Pearson chi-square.

Of 100 respondents, all received ≥ 1 SARS-CoV-2 vaccine before or shortly after enrollment, with 44% (n = 44) vaccinated in pregnancy and 56% (n = 56) while lactating. Participants reported vaccination counseling by obstetric (n = 48; 70%) and pediatric (n = 25; 36%) providers. Thirty-two percent (n = 32) received no advice on SARS-CoV-2 vaccination from healthcare providers, while 69% (n = 69) were counseled that vaccination was safe and beneficial.

While 6% (n = 6) and 5% (n = 5) reported concerns about the safety of maternal vaccines for lactating people or their infants, respectively, 12% (n = 12) and 9% (n = 9) expressed concerns about the safety of maternal SARS-CoV-2 vaccination in particular.

Despite high uptake of SARS-CoV-2 vaccine among participants, safety concerns persisted, with many reporting a lack of direct counseling from providers. Future research should investigate how variability in provider counseling affects SARS-CoV-2 vaccine uptake in perinatal populations.

The World Health Organization recommends that infants should be exclusively breastfed for the first 6 months of life and that breastfeeding should continue for 2 years and beyond. Most women initiate breastfeeding, but many do not continue for the recommended duration. While midwife-led continuity of antenatal care is linked to improved mother and infant outcomes, the influence on breastfeeding duration has not been previously reviewed.

To critically analyze the literature that compared midwife-led continuity of antenatal care with other models of care where researchers have measured breastfeeding duration beyond postpartum hospital discharge.

A systematic literature review with critical analysis was used to answer the research aim. We systematically searched and screened five databases for quantitative studies where researchers had reported breastfeeding duration beyond postpartum hospital discharge after midwife-led continuity of antenatal care, compared with another model of antenatal care. Methodological quality was assessed using tools from the Cochrane Collaboration (RoB2 and ROBINS-I). In total, nine studies met the inclusion criteria.

Clear conclusions about the association between midwife-led continuity of antenatal care and breastfeeding duration were not found. The risk of bias within non-randomized studies ranged from serious to critical, and a judgement of “some concerns” of risk of bias in the one randomized study.

To date, the question of whether midwife-led continuity of antenatal care improves breastfeeding duration has not been established. There has been a lack of consistency in definitions of breastfeeding and descriptions of models of care, which has weakened the evidence-based of literature reviewed.

Our review protocol was registered with PROSPERO; although due to COVID-19, this registration was not checked for eligibility by the PROSPERO team (CRD42020151276). https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020151276

Breastfeeding has been the subject of scientific studies for many years. Identifying the current trends and hotspots in breastfeeding research can further advance understanding in the field.

This study aimed to review the basic and conceptual structure of the literature on breastfeeding from a macro perspective.

The dataset for this study included 8,509 articles published between 1980 and 2022 accessed through the Web of Science database. Bibliometric methods were used to assess the growth direction of the literature on breastfeeding, the publication performance by country, influential journals and articles, co-citation networks, and keywords.

Research on breastfeeding developed slowly until the 2000s, at which point the speed of growth increased. The United States was the country in which most of the breastfeeding research was produced as well as being at the center of international collaborative networks. An examination of author productivity established that there was no specialization in breastfeeding. The results of citation and keyword analyses demonstrated that the literature on breastfeeding is sensitive to current developments, and the psychological aspects of breastfeeding have been intensively discussed, especially in recent years. Moreover, our results demonstrate that breastfeeding support programs are a distinct area if interest. Despite the abundance of research available, more studies are needed for specialization in this field.

This broad overview of the field of breastfeeding research can inform the direction and advancement of the literature.

Exclusive breastfeeding practice for 6 months is a critical global public health goal. In 2020, only 44% of infants globally, 31% in Central and West Africa, and 43% in Ghana, were exclusively breastfed for the first 6 months of life.

To critically evaluate disparities in exclusive breastfeeding practice for 6 months in Ghana.

The scoping review was guided by Arksey and O’Malley’s (2005) six-stage scoping review process. The online databases of American Psychological Association PsychInfo (APA PsychInfo), Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, and Scopus were searched with keywords inclusive of Ghana, exclusive breastfeeding, breastfeeding, infant feeding, lactation, lactating, and exclusive. Eligibility criteria included full-text, peer-reviewed research articles written in the English language without limitation to specific years. Data were analyzed thematically.

Initially, 317 records were identified, and 15 full-text articles were eligible for the scoping review. Four main themes emerged as disparities in exclusive breastfeeding practice in Ghana. The themes were healthcare (prenatal clinic visits, delivery place, exclusive breastfeeding knowledge), personal (maternal age, Human Immunodeficiency Virus status, parity, type of delivery, breast problem), employment (unemployed, formal, or informal sector worker), and sociocultural (ethnicity/region, family support, religious beliefs, cultural practices).

Disparities in exclusive breastfeeding in Ghana warrant the collaborative efforts of stakeholders for successful mitigation. Future researchers should explore the role of religion and sociocultural practices to protect, promote, and support 6 months of exclusive breastfeeding in Ghana.

Tandem breastfeeding is defined as a situation in which a mother continues breastfeeding her child through a subsequent pregnancy, including after the new baby is born. In some countries where motherhood may be delayed and the time between births may be reduced, support for the promotion of tandem breastfeeding is necessary to help mothers continue to breastfeed their eldest child and avoid early weaning. There is no existing research about mothers’ motivations to breastfeed in tandem.

To explore the motivations of women to initiate and maintain tandem breastfeeding, based on their lived experience, framed within the self-determination theory.

A prospective, cross-sectional, interpretive, phenomenological study was carried out through in-depth interviews with 15 mothers in Madrid, who had practiced tandem breastfeeding for more than 6 months, and whose weaning of their eldest child had occurred within the previous year. Convenience and snowball sampling were used. The data were analyzed using an established interpretive phenomenological analysis process.

Among the motivations for initiating tandem breastfeeding, the following themes were identified: “avoid wasting the effort invested,” “desire such life experience,” and “exercise the freedom to decide.” The motivations for maintaining tandem breastfeeding were classified as “pass on parenting values” and “benefits of teamwork.”

The participants based their motivation to tandem breastfeed to follow their freely chosen motherhood model. They discovered the advantages of its implementation, forming a team of themselves and their children, and healing their traumatic perinatal experiences.

Women with a cancer history report high distress during pregnancy and infant feeding. Despite the clear advantages of breastfeeding, little is known about factors influencing infant feeding behavior in women with cancer history.

This three-time point longitudinal study aimed to explore the centrality of pregnancy and infant feeding experiences in 17 pregnant women with a cancer history (cases) compared to 17 pregnant women without cancer history (controls).

During pregnancy, participants filled out the Centrality of Events Scale and an ad hoc questionnaire about specific emotions, concerns, and expectations about infant feeding (T1), and their childbirth and infant feeding experiences during hospitalization (T2), and at 3-months postpartum (T3).

Results at T1 demonstrated that participants with a history of cancer reported a higher perception of negative judgment and moral choice about breastfeeding than participants without a history of cancer. At T2 they reported a more positive childbirth experience than controls. From T2 to T3 participants with a history of cancer breastfed at a higher percentage than controls, and at T3 they reported higher levels of emotional and physical pleasure about the infant feeding experiences.

Women with cancer history may experience a higher emotional and physical pleasure with infant feeding. Despite initial difficulties, a greater prevalence of breastfeeding was present for women with a history of cancer. Although this is a small sample, this research suggests that support and promotion of breastfeeding might be very effective after a serious medical diagnosis.

Induction of lactation in a non-gestational parent has numerous potential benefits including parent–child bonding, optimal nutrition, and health benefits to the child and breast- or chest-feeding parent. For transgender women and nonbinary people on estrogen-based, gender-affirming hormone therapy, the ability to nourish their infants through production of their own milk may also be a profoundly gender-affirming experience. Two prior case studies have been published describing induced lactation in transgender women, but analysis of the nutritional quality of the milk produced has not been previously described.

Here we describe the experience of a transgender woman who underwent successful induction of lactation in order to breastfeed her infant, who was gestated by her partner.

Through modification of exogenous hormone therapy, use of domperidone as a galactogogue, breast pumping, and ultimately direct breastfeeding, the participant was able to co-feed her infant for the first 4 months of life. We provide a detailed description and timeline of the medications used, laboratory and electrocardiographic measurements, results of the participant’s milk analysis showing robust macronutrient content, and description of the participant’s experience in her own words.

These findings provide reassurance about the adequacy of nutrition from human milk produced by non-gestational transgender female and nonbinary parents on estrogen-based, gender-affirming hormone therapy, and support the importance of this experience on a personal level.

Despite limited clinical consensus regarding surgery for tethered oral tissues (“tongue-tie”) for resolving breastfeeding-related issues, the procedure has been increasing in the United States. Greater understanding of maternal experiences with obtaining surgical release may help to improve breastfeeding outcomes.

To explore experiences of breastfeeding mothers with infants having undergone “tongue-tie” surgery.

This online, cross-sectional, observational survey occurred between August and September 2020. Eligibility included being ≥ 18 years of age and previously or currently breastfeeding an infant with ≥ 1 tissue surgically released. Of 463 screens, 318 mothers were eligible and 115 consented. The final sample was 90.

The sample was predominantly white (n = 86; 95%), non-Hispanic (n = 84; 93%), married/cohabitating (n = 85; 94%), and currently providing their own milk (n = 81; 89%).

Difficult latch was the primary reason for seeking help. Participants reported lingual (n = 84; 93%), labial (n = 79; 88%), and buccal (n = 16; 17%) tissue-release, with 80% (n = 73) reporting > 1 released. For each tissue released, > 80% (n = 72) of participants felt “very confident” in their ability to correctly identify it and 97% (n = 87) felt “very involved” and “strongly agreed” with surgical release. International Board Certified Lactation Consultants^® were the most frequently identified source of information (n = 45; 50%) and referrals (n = 38; 42%), while pediatric dentists most frequently performed interventions (n = 60; 67%).

Participants reported being confident, involved, and in agreement with surgical release and lactation support professionals were frequent information and referral sources.

Labels are a key element of the marketing strategies of infant formula companies, and often include text or images that idealize their use, undermining efforts to promote breastfeeding.

To evaluate the prevalence of marketing cues that idealize infant formula on labels of products commercialized in Uruguay and to assess changes after a periodic monitoring of compliance with the International Code of Marketing of Breast-Milk Substitutes (IC).

This study is a descriptive, observational, and longitudinal assessment of the information included on infant formula labels. The first data collection was in 2019, as part of a periodic assessment to monitor the marketing of human-milk substitutes. In 2021, the same products were purchased to evaluate changes in their labels. Thirty-eight products were identified in 2019, of which 33 were still available in 2021. All information available on the labels was analyzed through content analysis.

Most products included at least one textual or visual marketing cue idealizing infant formula in both 2019 (n = 30, 91%) and 2021 (n = 29, 88%). This represents a violation of both the IC and national regulations. References to nutritional composition were the most frequent marketing cue, followed by references to child growth and development. No relevant changes were observed after the periodic assessment conducted by the Uruguayan government.

Monitoring compliance with the IC per se cannot be expected to trigger changes in the marketing strategies of infant formula companies. More explicit regulations and strong enforcement mechanisms are needed to end the inappropriate marketing practices on infant formula labels.

Recent calls-to-action have recommended the use of gender-inclusive language in the field of human lactation research and clinical care. However, little empirical evidence about parental acceptance and understanding of this new terminology exists.

To assess understanding and acceptance of an inclusive language revision of the Breastfeeding Attrition Prediction Tool (BAPT).

This was a prospective qualitative study consisting of two phases, a survey followed by cognitive interview. Pregnant people (N = 16) were recruited from the Vermont Special Supplemental Nutrition Program for Women, Infants, and Children, which uses the BAPT as a standard of care. The study team revised the BAPT (e.g., changed terms like “breast milk” to “human milk”). Study participants completed the Revised BAPT and then participated in a cognitive interview by phone to assess their understanding and acceptance of revised, inclusive language.

Most inclusive language was well understood and accepted by participants. Proposed revisions to the survey to replace terms like “breastfeeding” with other terms like “chestfeeding” or “bodyfeeding” were more difficult for participants to understand and were not well accepted.

While it is clear that language in human lactation research and clinical practice should be revised to be more gender inclusive, specific inclusive terms elicit different levels of understanding and acceptance. Inclusive language options should be tested with target populations and more research is needed in this area.

Parents with visual impairment can have difficulty in breastfeeding their babies. This situation may cause mothers to have negative feelings towards the care of their babies and to have problems during breastfeeding process.

To examine in detail (1) the breastfeeding experiences of mothers with visual impairment, and (2) the factors that facilitate and prevent these mothers from continuing to breastfeed.

This study was a cross-sectional, prospective generic qualitative design. The study sample (N = 15) consisted of mothers with visual impairment aged 18 and over, residing in Turkey, speaking Turkish, having an infant under the age of 2, and with breastfeeding experience. The analysis process was a content analysis approach. Data were collected through video or audio interviews using a semi-structured interview form.

Three main themes and 12 subthemes were determined: (1) negative emotions caused by breastfeeding, (2) barriers to initiating and maintaining breastfeeding, and (3) facilitators in initiating and maintaining breastfeeding.

The participants in our study stated that health personnel had limited information on how to communicate with and support them. For this reason, it is important that breastfeeding counselors and health care providers receive training about breastfeeding counseling for mothers with visual impairment so that they can provide information and advice to these mothers.
