Marketing of commercial milk formula: a system to capture parents, communities, science, and policy.

Despite proven benefits, less than half of infants and young children globally are breastfed in accordance with the recommendations of WHO. In comparison, commercial milk formula (CMF) sales have increased to about US$55 billion annually, with more infants and young children receiving formula products than ever. This Series paper describes the CMF marketing playbook and its influence on families, health professionals, science, and policy processes, drawing on national survey data, company reports, case studies, methodical scoping reviews, and two multicountry research studies. We report how CMF sales are driven by multifaceted, well resourced marketing strategies that portray CMF products, with little or no supporting evidence, as solutions to common infant health and developmental challenges in ways that systematically undermine breastfeeding. Digital platforms substantially extend the reach and influence of marketing while circumventing the International Code of Marketing of Breast-milk Substitutes. Creating an enabling policy environment for breastfeeding that is free from commercial influence requires greater political commitment, financial investment, CMF industry transparency, and sustained advocacy. A framework convention on the commercial marketing of food products for infants and children is needed to end CMF marketing.

The political economy of infant and young child feeding: confronting corporate power, overcoming structural barriers, and accelerating progress.

Despite increasing evidence about the value and importance of breastfeeding, less than half of the world's infants and young children (aged 0-36 months) are breastfed as recommended. This Series paper examines the social, political, and economic reasons for this problem. First, this paper highlights the power of the commercial milk formula (CMF) industry to commodify the feeding of infants and young children; influence policy at both national and international levels in ways that grow and sustain CMF markets; and externalise the social, environmental, and economic costs of CMF. Second, this paper examines how breastfeeding is undermined by economic policies and systems that ignore the value of care work by women, including breastfeeding, and by the inadequacy of maternity rights protection across the world, especially for poorer women. Third, this paper presents three reasons why health systems often do not provide adequate breastfeeding protection, promotion, and support. These reasons are the gendered and biomedical power systems that deny women-centred and culturally appropriate care; the economic and ideological factors that accept, and even encourage, commercial influence and conflicts of interest; and the fiscal and economic policies that leave governments with insufficient funds to adequately protect, promote, and support breastfeeding. We outline six sets of wide-ranging social, political, and economic reforms required to overcome these deeply embedded commercial and structural barriers to breastfeeding.

Breastfeeding: crucially important, but increasingly challenged in a market-driven world.

In this Series paper, we examine how mother and baby attributes at the individual level interact with breastfeeding determinants at other levels, how these interactions drive breastfeeding outcomes, and what policies and interventions are necessary to achieve optimal breastfeeding. About one in three neonates in low-income and middle-income countries receive prelacteal feeds, and only one in two neonates are put to the breast within the first hour of life. Prelacteal feeds are strongly associated with delayed initiation of breastfeeding. Self-reported insufficient milk continues to be one of the most common reasons for introducing commercial milk formula (CMF) and stopping breastfeeding. Parents and health professionals frequently misinterpret typical, unsettled baby behaviours as signs of milk insufficiency or inadequacy. In our market-driven world and in violation of the WHO International Code for Marketing of Breast-milk Substitutes, the CMF industry exploits concerns of parents about these behaviours with unfounded product claims and advertising messages. A synthesis of reviews between 2016 and 2021 and country-based case studies indicate that breastfeeding practices at a population level can be improved rapidly through multilevel and multicomponent interventions across the socioecological model and settings. Breastfeeding is not the sole responsibility of women and requires collective societal approaches that take gender inequities into consideration.

Experiences of breastfeeding peer counseling among women with low incomes in the US: a qualitative evaluation.

BACKGROUND: Person-centered breastfeeding counseling is a key but often overlooked aspect of high-quality services. We explored women's experiences of the Breastfeeding Heritage and Pride™ program, an evidence-based breastfeeding peer counseling program serving women with low incomes in the United States. METHODS: This study was conducted through an equitable community-clinical-academic partnership and guided by the World Health Organization (WHO) quality of care framework for maternal and newborn health, which highlights three domains of positive experiences of care: effective communication; respect and dignity; and emotional support. In-depth interviews were conducted with a purposive sample of women participating in the Breastfeeding Heritage and Pride™ program. Women were asked to describe their experiences with the program including examples of when good quality counseling was or was not provided. Each interview was conducted in English or Spanish, audio-recorded, and transcribed verbatim. Data were analyzed using reflexive thematic analysis. Once themes were generated, they were organized according to the three care experience domains in the WHO quality of care framework. RESULTS: Twenty-eight in-depth interviews were conducted with a racially/ethnically and socio-economically diverse sample of women. Three themes described effective communication practices of peer counselors: tailoring communication to meet women's individual needs; offering comprehensive and honest information about infant feeding; and being timely, proactive, and responsive in all communications across the maternity care continuum. Two themes captured why women felt respected. First, peer counselors were respectful in their interactions with women; they were courteous, patient, and non-judgmental and respected women's infant feeding decisions. Second, peer counselors showed genuine interest in the well-being of women and their families, beyond breastfeeding. The key theme related to emotional support explored ways in which peer counselors offered encouragement to women, namely by affirming women's efforts to breastfeed and by providing reassurance that alleviated their worries about breastfeeding. These positive experiences of counseling were appreciated by women. CONCLUSIONS: Women described having and valuing positive experiences in their interactions with peer counselors. Efforts to expand access to high-quality, person-centered breastfeeding counseling should, as part of quality assurance, include women's feedback on their experiences of these services.

A declaration on the value of experiential measures of food and water insecurity to improve science and policies in Latin America and the Caribbean.

BACKGROUND: Water security is necessary for good health, nutrition, and wellbeing, but experiences with water have not typically been measured. Given that measurement of experiences with food access, use, acceptability, and reliability (stability) has greatly expanded our ability to promote food security, there is an urgent need to similarly improve the measurement of water security. The Water InSecurity Experiences (WISE) Scales show promise in doing so because they capture user-side experiences with water in a more holistic and precise way than traditional supply- side indicators. Early use of the WISE Scales in Latin American & the Caribbean (LAC) has revealed great promise, although representative data are lacking for most of the region. Concurrent measurement of experiential food and water insecurity has the potential to inform the development of better-targeted interventions that can advance human and planetary health. MAIN TEXT: On April 20-21, 2023, policymakers, community organizers, and researchers convened at Universidad Iberoamericana in Mexico City to discuss lessons learned from using experiential measures of food and water insecurity in LAC. At the meeting's close, organizers read a Declaration that incorporated key meeting messages. The Declaration recognizes the magnitude and severity of the water crisis in the region as well as globally. It acknowledges that traditional measurement tools do not capture many salient water access, use, and reliability challenges. It recognizes that the WISE Scales have the potential to assess the magnitude of water insecurity more comprehensively and accurately at community, state, and national levels, as well as its (inequitable) relationship with poverty, poor health. As such, WISE data can play an important role in ensuring more accountability and strengthening water systems governance through improved public policies and programs. Declaration signatories express their willingness to promote the widespread use of the WISE Scales to understand the prevalence of water insecurity, guide investment decisions, measure the impacts of interventions and natural shocks, and improve public health. CONCLUSIONS: Fifty-three attendees endorsed the Declaration - available in English, Spanish and Portuguese- as an important step to making progress towards Sustainable Development Goal 6, "Clean Water and Sanitation for All", and towards the realization of the human right to water.

Consumption of sugar-sweetened beverages and T2D diabetes in the Eastern Caribbean.

OBJECTIVE: Sugar-sweetened beverages (SSB) are implicated in the increasing risk of diabetes in the Caribbean. Few studies have examined associations between SSB consumption and diabetes in the Caribbean. DESIGN: SSB was measured as teaspoon/d using questions from the National Cancer Institute Dietary Screener Questionnaire about intake of soda, juice and coffee/tea during the past month. Diabetes was measured using self-report, HbA1C and use of medication. Logistic regression was used to examine associations. SETTING: Baseline data from the Eastern Caribbean Health Outcomes Research Network Cohort Study (ECS), collected in Barbados, Puerto Rico, Trinidad and Tobago and US Virgin Islands, were used for analysis. PARTICIPANTS: Participants (n 1701) enrolled in the ECS. RESULTS: Thirty-six percentage of participants were unaware of their diabetes, 33% aware and 31% normoglycaemic. Total mean intake of added sugar from SSB was higher among persons 40-49 (9·4 tsp/d), men (9·2 tsp/d) and persons with low education (7·0 tsp/d). Participants who were unaware (7·4 tsp/d) or did not have diabetes (7·6 tsp/d) had higher mean SSB intake compared to those with known diabetes (5·6 tsp/d). In multivariate analysis, total added sugar from beverages was not significantly associated with diabetes status. Results by beverage type showed consumption of added sugar from soda was associated with greater odds of known (OR = 1·37, 95 % CI (1·03, 1·82)) and unknown diabetes (OR = 1·54, 95 % CI (1·12, 2·13)). CONCLUSIONS: Findings indicate the need for continued implementation and evaluation of policies and interventions to reduce SSB consumption in the Caribbean.

Systematic review and meta-analysis of breastfeeding and later overweight or obesity expands on previous study for World Health Organization.

AIM: To update a systematic review and meta-analysis of the association of breastfeeding with overweight or obesity that had been commissioned by the World Health Organization. We also assessed the likelihood of residual confounding. METHODS: Two independent reviewers searched MEDLINE, LILACS and Web of Science for manuscripts published between August 2014 and May 2021. Studies that only evaluated infants were excluded. Random-effects models were used to pool the estimates. RESULTS: The review comprised 159 studies with 169 estimates on the association of breastfeeding with overweight or obesity, and most of the studies were carried out among individuals aged 1-9 years (n = 130). Breastfeeding protected against overweight or obesity (pooled odds ratio:0.73, 95% confidence interval:0.71; 0.76). And, even among the 19 studies that were less susceptible to publication bias, residual confounding and misclassification, a benefit was observed (pooled odds ratio:0.85, 95% confidence interval:0.77; 0.93). Among those studies that were clearly susceptible to positive confounding by socioeconomic status, a benefit of breastfeeding was observed even after adjusting for socioeconomic status (pooled odds ratio:0.76, 95% confidence interval: 0.69; 0.83). CONCLUSION: Breastfeeding reduced the odds of overweight or obesity, and this association was unlikely to be due to publication bias and residual confounding.

Viabilidad de una escala de experiencias de inseguridad del agua en hogares mexicanos.

OBJETIVO: Identificar la viabilidad de la Escala de Experiencias de Inseguridad del Agua en el Hogar (Household Water Insecurity Experiences Scale, HWISE, por sus siglas en inglés) como herramienta para evaluar las experiencias de hogares mexicanos en relación con la inseguridad en el acceso al agua. Material y métodos. La escala fue integrada en la Encuesta Nacional de Salud y Nutrición Continua 2021 (Ensanut Continua 2021) y se utilizaron tres criterios para evaluar su viabilidad: 1) Consistencia interna: Se aplicó la prueba Alfa de Cronbach para estimar la correlación entre los ítems de la escala. Se consideró un punto de corte de al menos 0.80 como criterio de confiabilidad; 2) Equivalencia de los ítems para distintos indicadores sociodemográficos; y 3) Variables asociadas con inseguridad del agua. RESULTADOS: La escala HWISE mostró: 1) Buena confiabilidad o consistencia interna (Alfa de Cronbach de 0.928); 2) comportamiento equivalente de los ítems en los contextos urbano y rural, en nueve regiones del país y por terciles de condiciones de bienestar; y 3) asociación significativa con variables predictoras de inseguridad del agua. CONCLUSIONES: La escala HWIS, adaptada para México, es apropiada para su uso en evaluar la condición de inseguridad del agua en hogares mexicanos.

Gearing to success with national breastfeeding programmes: The Becoming Breastfeeding Friendly (BBF) initiative experience.

Evidence-based policy toolboxes are essential for decision makers to effectively invest in and scale up maternal-child health and nutrition programs, and breastfeeding is no exception. This special issue focuses on the experiences implementing the Becoming Breastfeeding Friendly (BBF) toolbox in England, Scotland, and Wales. BBF is an initiative that includes a toolbox for decision making based on the Complex Adaptive System-based Breastfeeding Gear Model. The BBF initiative experience in Great Britain presented in this special issue illustrates how versatile BBF is as it can be readily adapted to the specific application context. In this instance one country, England was trained by the Yale School of Public Health team that developed BBF. England, in turn, trained and assisted Scotland and Wales with the implementation and oversight of BBF in those countries. The positive experience implementing BBF in Great Britain is fully consistent with findings related to this initiative in other countries with contrasting economic, social, political and health care systems; including Germany, Ghana, Mexico, Myanmar, and Samoa. In all instances BBF has led to breastfeeding policy improvements with strong implications for enabling breastfeeding environments including maternity benefits, workforce development, the Baby Friendly Hospital Initiative and behavior change communication campaigns. In conclusion, BBF is a powerful tool to help guide the effective scaling up of evidence-based programmes to advance breastfeeding protection, promotion and support globally.

Becoming breastfeeding friendly in Great Britain-Does implementation science work?

The Becoming Breastfeeding Friendly (BBF) in Great Britain study was conducted during 2017-2019 comprising three country studies: BBF England, Wales and Scotland. It was part of an international project being coordinated during the same period by the Yale School of Public Health across five world regions to inform countries and guide policies to improve the environment for the promotion, protection and support of breastfeeding. This paper reports on the application of the BBF process that is based on an implementation science approach, across the countries that constitute Great Britain (England, Wales and Scotland). The process involves assessing 54 benchmarks across eight interlocking gears that drive a country's 'engine' towards a sustainable policy approach to supporting, promoting and protecting breastfeeding. It takes a consensus-oriented approach to the evaluation of benchmarks and the development of recommendations. This paper provides a critical overview of how the process was conducted, the findings and recommendations that emerged and how these were managed. We draw on critical theory as a theoretical framework for explaining the different outcomes for each country and some considerations for future action.

Scaling up breastfeeding in England through the Becoming Breastfeeding Friendly initiative (BBF).

Breastfeeding is the most accessible and cost-effective activity available to public health and has been shown to be one of the most effective preventive measures mothers can take to protect their children's health. Despite the well-documented benefits, the UK has one of the lowest breastfeeding rates in the world. The Becoming Breastfeeding Friendly (BBF) toolkit was developed through highly structured technical and academic collaboration, led by Yale University. It provides an evidence-based process to help countries assess their breastfeeding status and readiness to scale up, and identifies concrete measures countries can take to sustainably increase breastfeeding rates, based on data-driven recommendations. BBF is grounded in the Breastfeeding Gear Model complex adaptive systems framework which is made up of eight simultaneous conditions that sustain breastfeeding. In 2018, a committee of multi-agency stakeholders implemented the BBF process in England, collecting evidence to score the 'gear' components of England's breastfeeding environment against 54 benchmarks. The Training and Programme Delivery gear received the highest score, attributable to existing learning outcomes for health professionals and practitioners, peer supporters and specialist services, although there is a need for greater coordination and integration. The lowest scores were given for Promotion and Coordination, Goals and Monitoring due to the lack of a dedicated national strategy for breastfeeding and poor sharing of localised strategies and programmes. The process generated clear recommendations highlighting the need for more robust routine infant feeding data collection and reporting, and the necessity for strengthening leadership, monitoring and oversight to scale up and sustain breastfeeding.

Barriers and facilitators to exclusive breastfeeding among Black mothers: A qualitative study utilizing a modified Barrier Analysis approach.

Breastfeeding has health benefits for both infants and mothers, yet Black mothers and infants are less likely to receive these benefits. Despite research showing no difference in breastfeeding intentions by race or ethnicity, inequities in breastfeeding rates persist, suggesting that Black mothers face unique barriers to meeting their breastfeeding intentions. The aim of this study is to identify barriers and facilitators that Black women perceive as important determinants of exclusively breastfeeding their children for at least 3 months after birth. Utilizing a Barrier Analysis approach, we conducted six focus group discussions, hearing from Black mothers who exclusively breastfed for 3 months and those who did not. Transcripts were coded starting with a priori parent codes based on theory-derived determinants mapped onto the Socioecological Model; themes were analysed for differences between groups. Facilitators found to be important specifically for women who exclusively breastfed for 3 months include self-efficacy, lactation support, appropriate lactation supplies, support of mothers and partners, prior knowledge of breastfeeding, strong intention before birth and perceptions of breastfeeding as money-saving. Barriers that arose more often among those who did not exclusively breastfeed for 3 months include inaccessible lactation support and supplies, difficulties with pumping, latching issues and perceptions of breastfeeding as time-consuming. Lack of access to and knowledge of breastfeeding laws and policies, as well as negative cultural norms or stigma, were important barriers across groups. This study supports the use of the Socioecological Model to design multicomponent interventions to increase exclusive breastfeeding outcomes for Black women.

Breastfeeding is associated with the intelligence of school-age children in Mexico.

Breastfeeding has been consistently associated with higher intelligence since childhood. However, this relation could be confounded due to maternal selection bias. We estimated the association between predominant breastfeeding and intelligence in school-age children considering potential selection bias and we simulated the intelligence gap reduction between low versus higher socioeconomic status children by increasing breastfeeding. We analysed predominant breastfeeding practices (breastmilk and water-based liquids) of children 0-3 years included in the Mexican Family Life Survey (MxFLS-1). Intelligence was estimated as the z-score of the abbreviated Raven score, measured at 6-12 years in the MxFLS-2 or MxFLS-3. We predicted breastfeeding duration among children with censored data with a Poisson model. We used the Heckman selection model to assess the association between breastfeeding and intelligence, correcting for selection bias and stratified by socioeconomic status. Results show after controlling for selection bias, a 1-month increase in predominant breastfeeding duration was associated with a 0.02 SD increase in the Raven z-score (p < 0.05). The children who were predominantly breastfed for 4-6 months versus <1 month had 0.16 SD higher Raven z-score (p < 0.05). No associations were found using multiple linear regression models. Among low socioeconomic status children, increasing predominantly breastfeeding duration to 6 months would increase their mean Raven z-score from -0.14 to -0.07 SD and reduce by 12.5% the intelligence gap with high socioeconomic status children. In conclusion, predominant breastfeeding duration was significantly associated with childhood intelligence after controlling for maternal selection bias. Increased breastfeeding duration may reduce poverty-driven intelligence inequities.

Disparities in early initiation of breast feeding and prelacteal feeding: A study of low- and middle-income countries.

BACKGROUND: Early initiation of breast feeding (EIBF) reduces the risk of neonatal mortality. However, only 45% of newborns are breast-fed within the first hour after birth and prelacteal feeding (PLF) is widely prevalent in low- and middle-income countries (LMICs). OBJECTIVE: To assess within- and between-country disparities in EIBF and PLF practices by household wealth and place of birth and to investigate the national-level correlation between these feeding indicators in LMICs. METHODS: Data from Demographic Health Surveys and Multiple Indicator Cluster Surveys (2010-2019) in 76 LMICs were used to investigate within-country disparities in EIBF, any PLF, milk-based prelacteal feeding (MPLF), and water-based prelacteal feeding (WPLF) by wealth quintiles and place of childbirth (institutional [private or public sector] or in-home) for children under two years. We examined the between-country Pearson's correlation between EIBF and types of PLF, later adjusted for per capita gross domestic product (GDP). RESULTS: No clear wealth-related differences were found for EIBF and WPLF; however, any PLF and MPLF were significantly higher in children belonging to the richest 20% of households but are also prevalent among lower income groups. Prevalence of any PLF was higher among institutional births in all LMICs, but especially for MPLF in private sector deliveries in East Asia & the Pacific, Eastern Europe & Central Asia, and Latin America & the Caribbean. WPLF was more common in all African regions. EIBF was inversely correlated with any PLF (r = -0.59, 95% CI -0.72, -0.42), MPLF (r = -0.41, 95% CI -0.58, -0.21) and WPLF (r = -0.34, 95% CI -0.53, -0.13). Adjustment for log-GDP did not affect the magnitude and direction of the results. CONCLUSION: Clear prorich disparities exist in the prevalence of PLF, especially MPLF. Children born in private sector facilities are more likely to receive MPLF. EIBF is negatively associated with PLF practices in LMICs. The promotion of better early feeding practices is urgent to achieve the Sustainable Development Goal to reduce neonatal mortality to 12 deaths per 1000 live births.

Passive Smoking Exposure Modifies Cardiovascular Structure and Function: Beijing Child Growth and Health Cohort (PROC) Study.

Passive smoking exposure in children is prevalent worldwide and exposes children to respiratory and systemic toxins. In this study, we enrolled 568 children to study how secondhand smoke (SHS) might affect children's cardiovascular health in China. The measurement of nicotine and its metabolites in urine showed that 78.9% of children were exposed to SHS. Children exposed to SHS had greater interventricular septum thickness (p = 0.005) and left ventricular mass index (p = 0.008) than nonexposed children. Urinary norcotinine levels were associated with increased ascending aorta diameter (ß = 0.10, 95%CI 0.02-0.17) and decreased left ventricular end systolic diameter (ß = -0.10, 95%CI -0.19 to -0.01). The effects of SHS exposure on cardiovascular function: norcotinine levels associated with lower left ventricular mass index (ß = -0.32, 95%CI -0.59 to -0.05), left ventricular end diastolic volume index (ß = -0.43, 95%CI -0.85 to -0.02), and left ventricular end systolic volume index (ß = -0.20, 95%CI -0.37 to -0.03). Moreover, there no no significant associations of nicotine, cotinine, and trans-3'-hydroxycotinine with cardiovascular health. Overall, SHS exposure in children remains prevalent in Beijing and may affect children's cardiovascular development, in both structure and function. It suggests that stricter and practical measures are needed toward the elimination of tobacco use in children's environments.

Estimating the costs for implementing a maternity leave cash transfer program for women employed in the informal sector in Brazil and Ghana.

BACKGROUND: Maternity leave policies are designed to protect gender equality and the health of mothers in the workforce and their children. However, maternity leave schemes are often linked to jobs in the formal sector economy. In low- and middle-income countries a large share of women work in the informal sector, and are not eligible to such benefit. This is worrisome from a social justice and a policy perspective and suggests the need for intervening. Costing the implementation of potential interventions is needed for facilitating informed decisions by policy makers. METHODS: We developed and applied a costing methodology to assess the cost of a maternity leave cash transfer to be operated in the informal sector of the economy in Brazil and Ghana, two countries with very different employment structures and socioeconomic contexts. We conducted sensitivity analysis by modeling different numbers of weeks covered. RESULTS: In Brazil, the cost of the maternity cash transfer would be between 0.004% and 0.02% of the GDP, while in Ghana it would range between 0.076% and 0.28% of the GDP. The relative cost of rolling out a maternity intervention in Brazil is between 2.2 to 3.2 times the cost in Ghana depending on the benchmark used to assess the welfare measure. The differences in costs between countries was related to differences in labor market structure as well as demographic characteristics. CONCLUSIONS: Findings show how a standard methodology that relies on routinely available information is feasible and could assist policymakers in estimating the costs of supporting a maternity cash transfer for women employed in the informal sector, such intervention is expected to contribute to social justice, gender equity, and health trajectories.

What will it take to increase breastfeeding?

The introduction for the Supplement in Maternal & Child Nutrition: What will it take to increase breastfeeding? describes the contribution of each of the articles included in this Supplement to the current evidence about the major structural challenges in place to overcome to improve breastfeeding practices, as well as the evidence-based policies and interventions that can be effective at advancing breastfeeding on a large scale to promote, protect and support breastfeeding.

Content analysis of breast milk substitutes marketing on Chinese e-commerce platforms.

China has the largest and fastest-growing breast milk substitutes (BMSs) market and a disproportionately low exclusive breastfeeding rate. Many BMS manufacturers have established Chinese e-commerce stores. This marketing is of concern as it is likely to undermine breastfeeding. This study aimed to identify: (1) the marketing themes and strategies used to promote BMSs on the Chinese BMSs e-commerce websites; (2) if and how digital BMSs marketing may deviate from the World Health Organization Code of Marketing of Breast Milk Substitutes (the Code) recommendations. Content analysis was conducted on the flagship websites of 10 BMSs companies on the Chinese e-commerce platform "TMall" in July 2019. The main landing page (n = 10) of the flagship TMall website and the product description page (n = 113) of all individual formulas (Stages 1-3) within each company's TMall website were examined. The content was analysed and coded using an iterative thematic analysis approach. Emphasis on Premiumization and Science & Nutrition was the most commonly used marketing approaches. A total of 27.4% of the product description pages sampled used images of infants (<12 months), 33.6% made favourable comparisons of BMSs to breast milk, and only 34.5% included probreastfeeding statements. Marketing strategies were often inconsistent with the Code, and companies used "creative" ways to target mothers, often circumventing the Code recommendations. Unsubstantiated information was commonplace and of concern, because the e-commerce platform provided easy opportunities for bulk purchases. National regulatory actions are urgently needed to monitor online BMS marketing and the undermining of breastfeeding in China.

What works to protect, promote and support breastfeeding on a large scale: A review of reviews.

Globally women continue to face substantial barriers to breastfeeding. The 2016 Lancet Breastfeeding Series identified key barriers and reviewed effective interventions that address them. The present study updates the evidence base since 2016 using a review of reviews approach. Searches were implemented using the Epistomenikos database. One hundred and fifteen reviews of interventions were identified and assessed for quality and risk of bias. Over half of reviews (53%) were high- or moderate quality, with the remaining low or critically low quality due to weaknesses in assessment of bias. A large portion of studies addressed high-income and upper-middle income settings, (41%), and a majority (63%) addressed health systems, followed by community and family settings (39%). Findings from reviews continue to strengthen the evidence base for effective interventions that improve breastfeeding outcomes across all levels of the social-ecological model, including supportive workplace policies; implementation of the Baby-Friendly Hospital Initiative, skin to skin care, kangaroo mother care, and cup feeding in health settings; and the importance of continuity of care and support in community and family settings, via home visits delivered by CHWs, supported by fathers', grandmothers' and community involvement. Studies disproportionately focus on health systems in high income and upper-middle income settings. There is insufficient attention to policy and structural interventions, the workplace and there is a need for rigorous assessment of multilevel interventions. Evidence from the past 5 years demonstrates the need to build on well-established knowledge to scale up breastfeeding protection, promotion and support programmes.

Countries' experiences scaling up national breastfeeding, protection, promotion and support programmes: Comparative case studies analysis.

Scaling up effective interventions, policies and programmes can improve breastfeeding (BF) outcomes. Furthermore, considerable interest exists in learning from relatively recent successful efforts that can inform further scaling up, with appropriate adaptations, across countries. The purpose of this four-country case studies analysis was to examine why and how improvements in BF practices occurred across four contrasting countries; Burkina Faso, the Philippines, Mexico and the United States of America. Literature reviews and key informant interviews were conducted to document BF trends over time, in addition to why and how BF protection, promotion and support policies and programmes were implemented at a national level. A qualitative thematic analysis was conducted. The 'Breastfeeding Gear Model' and RE-AIM (Reach; Effectiveness; Adoption; Implementation; and Maintenance) frameworks were used to understand and map the factors facilitating or hindering the scale up of the national programmes and corresponding improvements in BF practices. Each of the studied countries had different processes and timing to implement and scale up programmes to promote, protect and support breastfeeding. However, in all four countries, evidence-based advocacy, multisectoral political will, financing, research and evaluation, and coordination were key to fostering an enabling environment for BF. Furthermore, in all countries, lack of adequate maternity protection and the aggressive marketing of the breast-milk substitutes industry remains a strong source of negative feedback loops that are undermining investments in BF programmes. Country-specific best practices included innovative legislative measures (Philippines), monitoring and evaluation systems (United States of America), engagement of civil society (Mexico) and behavior change communication BF promotion (Burkina Faso) initiatives. There is an urgent need to improve maternity protection and to strongly enforce the WHO Code of Marketing of Breast-Milk Substitutes.
