Introduction Recommendations for the clinical management of new mothers with suspected or confirmed COVID-19 and their infants are required. Guidance must weigh the risk posed by transmission of SARS-CoV-2 against the protection that maternal proximity and breastfeeding provide infants. Our aim was to review international COVID-19 guidance for maternal and newborn care, assessing alignment with WHO recommendations and the extent to which policy supported or undermined breastfeeding. Methods Guidance documents from 33 countries on the care of infants whose mothers were suspected or confirmed as having COVID-19 were assessed for alignment with WHO recommendations regarding: (1) skin-to-skin contact; (2) early initiation of breastfeeding; (3); rooming-in; (4) direct breastfeeding; (5) provision of expressed breastmilk; (6) provision of donor human milk; (7) wet nursing; (8) provision of breastmilk substitutes; (9) psychological support for separated mothers; and (10) psychological support for separated infants. Results Considerable inconsistency in recommendations were found. Recommendations against practices supportive of breastfeeding were common, even in countries with high infant mortality rates. None of the guidance documents reviewed recommended all aspects of WHO guidance. The presence of influential guidance conflicting with WHO recommendations and an undervaluing of the importance of maternal proximity and breastfeeding to infant health appeared to contribute to this poor alignment. Conclusion Those developing guidance in the COVID-19 pandemic and other infectious disease outbreaks need to appropriately consider the importance of skin-to-skin contact, early initiation of breastfeeding, rooming-in and breastfeeding to maternal and infant physical and psychological health. In weighing the value of recommendations of others in future guidance development, countries should consider past reliability and value placed on breastfeeding. Recommendations against maternal proximity and breastfeeding should not be made without compelling evidence that they are necessary, and less harmful than maintaining dyad integrity.

Maternity protection is a normative fundamental human right that enables women to combine their productive and reproductive roles, including breastfeeding. The aim of this study is to examine the uptake of Vietnam’s maternity protection policy in terms of entitlements and awareness, perceptions, and gaps in implementation through the lens of formally employed women. In this mixed methods study, we interviewed 494 formally employed female workers, among whom 107 were pregnant and 387 were mothers of infants and conducted in-depth interviews with a subset of these women (n = 39). Of the 494 women interviewed, 268 (54.3%) were working in blue-collar jobs and more than 90% were contributing to the public social insurance fund. Among the 387 mothers on paid maternity leave, 51 (13.2%) did not receive cash entitlements during their leave. Among the 182 mothers with infants aged 6–11 months, 30 (16.5%) returned to work before accruing 180 days of maternity leave. Of 121 women who had returned to work, 26 (21.5%) did not receive a one-hour paid break every day to express breastmilk, relax, or breastfeed, and 46 (38.0%) worked the same or more hours per day than before maternity leave. Although most women perceived maternity leave as beneficial for the child’s health (92.5%), mother’s health (91.5%), family (86.2%), and society (90.7%), fewer women perceived it as beneficial for their income (59.5%), career (46.4%), and employers (30.4%). Not all formally employed women were aware of their maternity protection rights: women were more likely to mention the six-month paid maternity leave (78.7%) and one-hour nursing break (62.3%) than the other nine entitlements (2.0–35.0%). In-depth interviews with pregnant women and mothers of infants supported findings from the quantitative survey. In conclusion, although Vietnam’s maternity protection policy helps protect the rights of women and children, our study identified implementation gaps that limit its effectiveness. To ensure that all women and their families can fully benefit from maternity protection, there is a need to increase awareness of the full set of maternity entitlements, strengthen enforcement of existing policies, and expand entitlements to the informal sector.

Background: Rates of early initiation of breastfeeding are low in Southeast Asia, despite evidence that increased initiation of early breastfeeding would lead to better long-term infant and child health and decrease inequities in long-term health and well-being. In response, a novel performance-based, baby-friendly hospital program designates hospitals that adhere to evidence-based early essential newborn care (EENC) and breastfeeding interventions as Centers of Excellence for Breastfeeding (COE). This study examined whether hospital participation in the program was associated with better breastfeeding outcomes. Methods: Hospitals (n = 28) were invited into the program in December 2018. Hospitals developed an improvement plan for promoting a breastfeeding-friendly environment and meeting the standards of the COE accreditation process and were enrolled on a rolling basis over the course of a year. Post-partum surveys were conducted with parents (n = 9585) from January 2019 through April 2020 to assess their breastfeeding and post-partum experience. Segmented regression models were used to assess how breastfeeding outcomes evolved before and after hospital enrollment in the COE program. Results: Enrollment was associated with a 6 percentage-point (95% CI: 3, 9) increase in the level of early initiation of breastfeeding, which continued to increase in the post-enrollment period, and a 5 percentage-point (95% CI: 2, 9) increase in the level of exclusive breastfeeding during hospital stay. We did not observe evidence that enrollment was immediately associated with receipt of lactation counseling or exclusive breastfeeding at survey time. Conclusion: The prevalence of early and exclusive breastfeeding increased after enrollment in the COE program, suggesting that the program has the potential to improve breastfeeding initiation rates and longer-term child health and well-being. Further research should be conducted to examine whether the program has an impact on the overall duration of breastfeeding.

Background/Objectives: There is extensive evidence that breastfeeding saves lives, improves health, and provides value to the economy and societies worldwide. The Philippines and Viet Nam have progressive policies to enable breastfeeding, and breastfeeding rates in these countries have substantively improved. In the Philippines, exclusive breastfeeding under six months (EBF) increased from 35.9% (2008) to 60.1% (2021) and, in Viet Nam, in just over a decade, EBF has more than doubled, from 17.0% (2010) to 45.4% (2021). We aimed to use an evidence synthesis to consolidate learnings from policy support to enable breastfeeding in the Philippines and Viet Nam, to identify insights to improve future programming to improve breastfeeding practices in these two countries, and glean learnings that can potentially be adapted for similar contexts. Methods: This manuscript presents a qualitative evidence synthesis of seven purposively selected research articles from the Philippines and Viet Nam. Results: Since the 1960s, the Philippines and Viet Nam have notably improved policies protecting breastfeeding. Both countries have implemented legislation that is substantially aligned with the International Code of Marketing of Breast-milk Substitutes and subsequent World Health Assembly resolutions. Both countries have improved paid maternity leave provisions, with Viet Nam providing 6 months of paid leave, yet insufficient coverage to informal workers, and the Philippines providing 3.5 months of paid maternity leave while expanding maternity protection coverage to informal workers. From 2006–2021, breastfeeding rates increased in both countries alongside policy improvements yet barriers to implementation remain. Conclusions: Implementation research has documented policy progress and improved breastfeeding rates in the Philippines and Viet Nam. Our analysis offers valuable lessons potentially applicable beyond these contexts, emphasizing the need for addressing policy gaps and targeted cross-sectoral policy actions to enhance breastfeeding practices. Learnings from implementing national marketing restrictions of commercial milk formula and associated products and maternity protection policies in these countries could inform the implementation of newly developed regional standards together with supportive policies, facilitating the harmonization of regional regulatory environments.

The market for commercially produced complementary foods (CPCF) is rapidly expanding in Southeast Asia; however, the existence and content of mandatory national policies, standards and legislation (binding legal measures) for CPCF in the region is unclear. To assess the status of national binding legal measures for CPCF in Southeast Asia, a legal and policy desk review was conducted in seven countries (Cambodia, Laos People's Democratic Republic, Indonesia, Malaysia, Philippines, Thailand and Viet Nam). The alignment of the national binding legal measures relevant to CPCF was assessed against guidance on CPCF nutrient composition and labelling requirements provided by Codex Alimentarius and the World Health Organization (WHO). Each of the seven countries had at least two national binding legal measures related to the nutrient composition or labelling of CPCF; however, there was limited alignment with the guidance from Codex and WHO. No country was fully aligned with the three CPCF‐specific Codex standards/guidelines and only one country was in full alignment with the recommendations related to the protection of breastfeeding from the ‘WHO Guidance on ending the inappropriate promotion of foods for infants and young children’. The findings of the review indicate that the existing national binding legal measures are insufficient to ensure that the CPCF sold as suitable for older infants and young children are nutritionally adequate and labelled in a responsible manner that does not mislead caregivers. Improved and enforced national binding legal measures for CPCF, in alignment with global guidance, are required to ensure that countries protect, promote and support optimal nutrition for children 6–36 months of age.

(1) Background: Routine episiotomy is not recommended by international guidelines; however, it occurs at a high rate in Vietnam. (2) Methods: A process to reduce unnecessary episiotomies was developed and implemented as part of the Centers of Excellence for Breastfeeding initiative, which aims to deliver high-quality breastfeeding and early essential newborn care services within a supportive policy environment. The aim of this project report is to outline the steps undertaken to reduce episiotomies, the experience in pilot hospitals, and the process towards changing policy. (3) Results: During the 14 months following the change in episiotomy policy, pilot hospital records showed no infant death or injury. Monthly monitoring data from four pilot hospitals showed that the prevalence of episiotomy was substantially lower than the average in national hospitals in Vietnam. Facilitators to reducing the episiotomy rate include the incentive of Centers of Excellence for Breastfeeding designation and supportive hospital leadership. Challenges include the ambiguity of Vietnam’s national guideline on episiotomy and lack of routine monitoring on the episiotomy rate and indications. (4) Discussion: Our experience suggests that through training and routine monitoring hospitals can apply a policy of selective episiotomy and reduce the practice, particularly among multiparous women, and improve breastfeeding rates.(5) Conclusions: Sharing our experience of implementing this process and offering four areas for action will hopefully contribute to expanded use of mother-friendly, evidence-based care as policy and routine practice in Vietnam and similar settings.
