Background:Understanding the motivational factors that influence breastfeeding behavior is critical for addressing suboptimal breastfeeding outcomes. Self-determination theory has been used as a framework to understand these factors.Research Aim:The aim of this article is to identify and critically review breastfeeding instruments derived from self-determination theory and their subsequent uses in the literature.Method:This critical review was guided by Grant and Booth’s typological description. Eligibility criteria included full-text, peer-reviewed original instrument development and validation articles, written in the English language without limitation to specific years. Articles describing the use of the eligible instruments were also included. There were 164 articles identified initially, and four instruments were included in the final sample. Finally, five articles, including subsequent uses of the instruments were critically analyzed and an overview, assessment of validation, and analysis of subsequent use of each instrument is presented.Results:All instruments examine the degree of autonomy underlying breastfeeding motivation. The extent and quality of validation varied. Two instruments have been used in subsequent studies; one was adapted and translated into Turkish and used in three other studies, and another was used in full in one subsequent use and in part in another study. Three of four were initially developed for prenatal administration.Conclusions:Instruments derived from self-determination theory hold promise in exploring the autonomy underlying breastfeeding motivations. Researchers who wish to use or adapt these instruments should consider the instruments’ domains, validity, and administration. New measures are needed to explore other constructs from self-determination theory related to breastfeeding.

Background:SARS-CoV-2 specific antibodies exist in human milk expressed by lactating parents after vaccination. In the existing research, the effects of vaccine types on human milk are inconsistent.Research Aim:This study aims to perform a systematic review and meta-analysis of the existing observational studies to compare the positive rates of SARS-CoV-2 specific antibodies in human milk according to mRNA and adenovector-based vaccination.Methods:PubMed, Web of Science, Elsevier Science Direct and Cochrane Library databases were systematically searched for relevant articles published from December 30, 2019 to February 15, 2023. Observational studies were considered eligible provided they reported data on SARS-CoV-2 specific antibodies in human milk. The risk of bias in non-randomized studies of interventions (ROBINS-I) tool, the Newcastle-Ottawa Scale (NOS), and the Agency for Healthcare Research and Quality (AHRQ) were used to assess risk of bias. Seven studies, including 511 lactating participants, were included in this review and meta-analysis.Results:The positive rate of SARS-CoV-2 IgA is higher in mRNA vaccine groups than in adenovector-based vaccine groups (OR = 4.80, 95% CI [3.04, 7.58], p < 0.001). The positive rate of SARS-CoV-2 IgG was higher in mRNA vaccines than in adenovector-based vaccines.Conclusions:Compared to adenovector-based vaccines, mRNA vaccines present a higher positivity rate of IgA and IgG in human milk after vaccination. In other words, mRNA vaccinations may offer breastfed children a higher level of protection than adenovector-based vaccinations. Further high-quality data is still required to substantiate these findings.

The World Health Organization recommends assessing compliance with key clinical practices of the Baby-Friendly Hospital Initiative (BFHI; Steps 3–9) using birthing women’s self-reports. Globally, compliance is mainly assessed using health staff reports, and the use of women’s self-reports in selected countries has deviated from the Global Standards for the BFHI. Therefore, we aimed to provide insight into the appropriate method of incorporating women’s self-reports in assessing compliance with Steps 3–9 of the BFHI. We developed questions and coding algorithms for assessing compliance with Steps 3–9 based on Global Standards for BFHI compliance, and implemented them via a cross-sectional survey of 302 women who gave birth to a live baby in Sri Lankan hospitals. Compliance with specific practices within each of Steps 3–9 and overall compliance with each step were described as percentages. Compliance with specific practices and each BFHI Step ranged from 15.9%–100% and 7.0%–100%, respectively. Our findings particularly emphasize the potentially enhanced usefulness and robustness of assessing all specific practices within BFHI key clinical steps and not focusing only on one practice within a step, to derive more useful health service guidance globally for capturing BFHI compliance and its impact on breastfeeding outcomes. This method could be translated across multiple settings globally. It would enable more specific identification of care advancements required by health services to improve the effectiveness of breastfeeding support and address the prevailing undervaluing and under-use of women’s experiential data to evaluate and guide health service improvement.

Background:Breastfeeding is a parenting practice that combines close intimate contact with the opportunity to be sensitive and responsive to the infant, and may have direct and indirect relations with infant attachment. However, researchers have produced inconsistent findings, suggesting there may be other mechanisms involved. Coparenting may play a significant role, as it has been consistently associated with mother–infant relationships.Research aims:The aims of this study were to examine: (1) whether breastfeeding would be directly associated with infant–mother attachment; (2) whether this association was also indirect, through mothers’ quality of caregiving; and (3) whether partners’ coparenting support moderates breastfeeding’s indirect association with attachmentMethods:This was a prospective, longitudinal study that drew data from a larger NIH-funded study on sleep and family relationships (R01HD052809). Mothers reported on their feeding practices and coparenting relationships. Independent observations were used to assess mothers’ emotional availability toward infants. A separate team of observers assessed infant–mother attachment.Results:Exclusive breastfeeding during the first 6 months, and longer duration of any breastfeeding across the 1st year, were directly associated with more secure infant–mother attachment. These associations were also indirect, through maternal emotional availability. Coparenting was a significant moderator, such that the influence of longer breastfeeding duration on improved emotional availability, and, in turn, on more secure attachment, was significant only for mothers who perceived coparenting quality to be low.Conclusion:Findings highlighted the importance of breastfeeding on both the quality of mothering and infant attachment, but also emphasized that coparenting support may be particularly important for mothers who are unable to breastfeed.
