RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Policy-makers need to rethink the connections between the economy and health. The World Health Organization Council on the Economics of Health for All has called for human and planetary health and well-being to be moved to the core of decision-making to build economies for health. Doing so involves valuing and measuring what matters, more and better health financing, innovation for the common good and rebuilding public sector capacity. We build on this thinking to argue that breastfeeding should be recognized in food and well-being statistics, while investments in breastfeeding should be considered a carbon offset in global financing arrangements for sustainable food, health and economic systems. Breastfeeding women nourish half the world's infants and young children with immense quantities of a highly valuable milk. This care work is not counted in gross domestic product or national food balance sheets, and yet ever-increasing commercial milk formula sales are counted. Achieving global nutrition targets for breastfeeding would realize far greater reductions in greenhouse gas emissions than decarbonizing commercial milk formula manufacturing. New metrics and financing mechanisms are needed to achieve the health, sustainability and equity gains from more optimal infant and young child feeding. Properly valuing crucial care and environmental resources in global and national measurement systems would redirect international financial resources away from expanding carbon-emitting activities, and towards what really matters, that is, health for all. Doing so should start with considering breastfeeding as the highest quality, local, sustainable first-food system for generations to come.


Les responsables politiques doivent repenser les liens entre économie et santé. Le Conseil de l'Organisation mondiale de la Santé sur l'économie de la santé pour tous a demandé que le bien-être et la santé, aussi bien de l'humain que de la planète, soient désormais au cœur du processus de prise de décisions afin de créer des économies au service de la santé. Il est donc impératif d'identifier et de valoriser ce qui compte, d'accroître et d'optimiser le financement de la santé, d'innover pour le bien commun et de renforcer les capacités du secteur public. En partant de cette réflexion, nous plaidons pour une reconnaissance de l'allaitement dans les statistiques relatives à l'alimentation et au bien-être, et estimons que tout investissement réalisé dans ce domaine devrait être considéré comme un crédit-carbone dans le cadre des modalités financières mondiales liées aux systèmes économiques et sanitaires ainsi qu'à une alimentation durable. Les femmes allaitantes nourrissent la moitié des enfants en bas âge dans le monde avec d'immenses quantités de lait extrêmement précieux. Ces activités de soins ne sont pas comptabilisées dans le produit intérieur brut ou les bilans alimentaires nationaux, contrairement aux ventes de lait maternisé en constante progression. Atteindre les cibles mondiales de nutrition pour l'allaitement contribuerait davantage à réduire les émissions de gaz à effet de serre que décarboner la production de lait maternisé. De nouveaux paramètres et mécanismes de financement sont nécessaires pour bénéficier des avantages en matière de santé, de durabilité et d'équité qui découlent d'une meilleure alimentation des nourrissons et jeunes enfants. Valoriser correctement les principales ressources consacrées à l'environnement et aux soins dans les systèmes de mesure nationaux et mondiaux permettrait de détourner les moyens financiers internationaux du développement d'activités à fort taux d'émissions pour les rediriger vers ce qui compte vraiment, c'est-à-dire la santé pour tous. Et pour y parvenir, la première étape consisterait à reconnaître l'allaitement comme l'aliment de base, local, durable et de qualité pour les générations futures.


Los responsables de formular las políticas deben volver a plantearse las conexiones entre la economía y la salud. El Consejo sobre la Economía de la Salud para Todos de la Organización Mundial de la Salud ha pedido que la salud y el bienestar humanos y del planeta se sitúen en el centro de la toma de decisiones a fin de desarrollar economías para la salud. Esto requiere valorar y medir lo que importa, más y mejor financiación sanitaria, innovación para el bien común y reconstrucción de la capacidad del sector público. Nos basamos en este pensamiento para argumentar que la lactancia materna debería reconocerse en las estadísticas de alimentación y bienestar, mientras que las inversiones en lactancia materna deberían considerarse como una compensación de emisiones de carbono en los acuerdos globales de financiación para sistemas alimentarios, sanitarios y económicos sostenibles. Las mujeres lactantes alimentan a la mitad de los bebés y niños pequeños del mundo con inmensas cantidades de una leche muy valiosa. Este trabajo de cuidados no se contabiliza en el producto interior bruto ni en los balances alimentarios nacionales y, sin embargo, sí se contabilizan las ventas cada vez mayores de leche de fórmula comercial. Alcanzar los objetivos mundiales de nutrición para la lactancia materna supondría una reducción mucho mayor de las emisiones de gases de efecto invernadero que descarbonizar la fabricación de leche de fórmula comercial. Se necesitan nuevas métricas y mecanismos de financiación para lograr los beneficios en materia de salud, sostenibilidad y equidad de una alimentación más óptima de los bebés y los niños pequeños. Una valoración adecuada de los cuidados esenciales y de los recursos medioambientales en los sistemas de medición globales y nacionales redirigiría los recursos financieros internacionales lejos de la expansión de las actividades que emiten carbono, y hacia lo que realmente importa, es decir, la salud para todos. En este contexto, habría que empezar por considerar la lactancia materna como el sistema de primera alimentación de mayor calidad, local y sostenible para las generaciones futuras.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVE: To investigate the prevalence and socio-economic inequalities in breast milk, breast milk substitutes (BMS) and other non-human milk consumption, by children under 2 years in low- and middle-income countries (LMIC). DESIGN: We analysed the prevalence of continued breast-feeding at 1 and 2 years and frequency of formula and other non-human milk consumption by age in months. Indicators were estimated through 24-h dietary recall. Absolute and relative wealth indicators were used to describe within- and between-country socio-economic inequalities. SETTING: Nationally representative surveys from 2010 onwards from eighty-six LMIC. PARTICIPANTS: 394 977 children aged under 2 years. RESULTS: Breast-feeding declined sharply as children became older in all LMIC, especially in upper-middle-income countries. BMS consumption peaked at 6 months of age in low/lower-middle-income countries and at around 12 months in upper-middle-income countries. Irrespective of country, BMS consumption was higher in children from wealthier families, and breast-feeding in children from poorer families. Multilevel linear regression analysis showed that BMS consumption was positively associated with absolute income, and breast-feeding negatively associated. Findings for other non-human milk consumption were less straightforward. Unmeasured factors at country level explained a substantial proportion of overall variability in BMS consumption and breast-feeding. CONCLUSIONS: Breast-feeding falls sharply as children become older, especially in wealthier families in upper-middle-income countries; this same group also consumes more BMS at any age. Country-level factors play an important role in explaining BMS consumption by all family wealth groups, suggesting that BMS marketing at national level might be partly responsible for the observed differences.

RESUMEN

Milk formula sales have grown globally, particularly through follow-up formulas (FUF) and growing-up milks (GUM). Marketing strategies and weak regulatory and institutional arrangements are important contributors to caregivers' decisions about child feeding choices. This study describes maternal awareness, beliefs, and normative referents of FUFs and GUMs among Mexican pregnant women and mothers of children 0-18 months (n = 1044) through the lens of the theory of reasoned action (TRA). A cross-sectional survey was undertaken in two large metropolitan areas of Mexico. Descriptive analyses were conducted following the constructs of the TRA. One-third of the participants had heard about FUFs, mainly through health professionals (51.1%) and family (22.2%). Once they had heard about FUFs, the majority (80%) believed older infants needed this product due to its benefits (hunger satisfaction, brain development, and allergy management). One quarter of the participants were already using or intended to use FUFs; the majority had received this recommendation from doctors (74.6%) and mothers/mothers-in-law (25%). Similarly, 19% of the women had heard about GUMs. The pattern for the rest of TRA constructs for GUMs was similar to FUFs. Mexican women are exposed to FUFs and GUMs, once women know about them, the majority believe older infant and young children need these products, stating perceived benefits that match the poorly substantiated marketing claims of breast-milk substitutes. Health professionals, particularly doctors, act as marketing channels for FUFs and GUMs. Marketing of FUFs and GUMs represents a threat to breastfeeding in Mexico and a more protective regulatory and institutional environment is needed.

RESUMEN

As breastfeeding is of utmost importance for child development and survival, identifying whether breast milk is a route of transmission for human viruses is critical. Based on the principle of Koch's postulate, we propose an analytical framework to determine the plausibility of viral transmission by breast milk. This framework is based on five criteria: viral infection in children receiving breast milk from infected mothers; the presence of virus, viral antigen, or viral genome in the breast milk of infected mothers; the evidence for the virus in breast milk being infectious; the attempts to rule out other transmission modalities; and the reproduction of viral transmission by oral inoculation in an animal model. We searched for evidence in published reports to determine whether the 5 criteria are fulfilled for 16 human viruses that are suspected to be transmissible by breast milk. We considered breast milk transmission is proven if all 5 criteria are fulfilled, as probable if 4 of the 5 criteria are met, as possible if 3 of the 5 criteria are fulfilled, and as unlikely if less than 3 criteria are met. Only five viruses have proven transmission through breast milk: human T-cell lymphotropic virus 1, human immunodeficiency virus, human cytomegalovirus, dengue virus, and Zika virus. The other 11 viruses fulfilled some but not all criteria and were categorized accordingly. Our framework analysis is useful for guiding public health recommendations and for identifying knowledge gaps amenable to original experiments.

RESUMEN

BACKGROUND: There is a high burden of depression globally, including in South Africa. Maternal depression is associated with poverty, unstable income, food insecurity, and lack of partner support, and may lead to poor outcomes for mothers and children. In South Africa one-third of working women are in informal work, which is associated with socioeconomic vulnerability. METHODS: A cross sectional survey explored work setting and conditions, food security and risk of depression among informal working women with young children (0-3 years). Depression risk was assessed using the Edinburgh Postnatal Depression Score (EPDS) and Whooley score. Food insecurity was evaluated using Household Food Insecurity Access Scale. Data was analysed using SPSS and Stata. RESULTS: Interviews were conducted with 265 informal women workers. Types of work included domestic work, home-based work, informal employees and own account workers, most of whom were informal traders. Most participants (149/265; 56.2%) earned between US$70-200 per month, but some participants (79/265; 29.8%) earned < US$70 per month, and few earned > US$200 per month (37/265; 14.0%). Many participants experienced mild (38/267; 14.3%), moderate (72/265; 27.2%) or severe (43/265; 16%) food insecurity. Severe food insecurity was significantly higher among participants with the lowest income compared to those with the highest income (p = 0.027). Women who received financial support from the baby's father were less likely to be food insecure (p = 0.03). Using EPDS scores, 22/265 (8.3%) women were designated as being at risk of depression. This was similar among postnatal women and women with older children. Household food insecurity was significantly associated with depression risk (p < 0.001). CONCLUSIONS: Informal women workers were shown to be vulnerable with low incomes and high rates of food insecurity, thus increasing the risk for poor maternal health. However, levels of depression risk were low compared to previous estimates in South Africa, suggesting that informal workers may have high levels of resilience. Interventions to improve social protection, access to health services, and support for safe childcare in the workplace could improve the health and wellbeing of these mothers and support them to care for their children.

RESUMEN

BACKGROUND: Returning to work after childbirth is challenging for working mothers. Childcare quality may have lifelong effects on children's health, development and cognitive function. Over 60% of working women globally are informal workers without employment or maternity protection, but little is known about how these women care for their children. METHODS: We conducted a mixed-methods longitudinal cohort study among informal women workers in Kwazulu-Natal, South Africa between July 2018 and August 2019. Participants were followed up from late pregnancy until they had returned to work. We conducted structured quantitative interviews and in-depth qualitative interviews at different time points: before and after the baby was born, and after returning to work. Subsequently, a photovoice activity was conducted with groups of participants to explore the childcare environment. We employed narrative thematic analysis for qualitative data and descriptive analysis for quantitative data. RESULTS: 24 women were recruited to participate. Women returned to work soon after the baby was born, often earlier than planned, because of financial responsibilities to provide for the household and new baby. Women had limited childcare choices and most preferred to leave their babies with family members at home, as the most convenient, low cost option. Otherwise, mothers chose paid carers or formal childcare. However, formal childcare was reported to be poor quality, unaffordable and not suited to needs of informal workers. Mothers expressed concern about carers' reliability and the safety of the childcare environment. Flexibility of informal work allowed some mothers to adapt their work to care for their child themselves, but others were unable to arrange consistent childcare, sometimes leaving the child with unsuitable carers to avoid losing paid work. Mothers were frequently anxious about leaving the child but felt they had no choice as they needed to work. CONCLUSION: Mothers in informal work had limited childcare options and children were exposed to unsafe, poor-quality care. Maternity protection for informal workers would support these mothers to stay home longer to care for themselves, their family and their baby. Provision of good quality, affordable childcare would provide stability for mothers and give these vulnerable children the opportunity to thrive.

RESUMEN

BACKGROUND: In contrast with the ample literature on within- and between-country inequalities in breastfeeding practices, there are no multi-country analyses of socioeconomic disparities in breastmilk substitute (BMS) consumption in low- and middle-income countries (LMICs). OBJECTIVE: This study aimed to investigate between- and within-country socioeconomic inequalities in breastfeeding and BMS consumption in LMICs. METHODS: We examined data from the Demographic Health Surveys and Multiple Indicator Cluster Surveys conducted in 90 LMICs since 2010 to calculate Pearson correlation coefficients between infant feeding indicators and per capita gross domestic product (GDP). Within-country inequalities in exclusive breastfeeding, intake of formula or other types of nonhuman milk (cow/goat) were studied for infants aged 0-5 mo, and for continued breastfeeding at ages 12-15 mo through graphical presentation of coverage wealth quintiles. RESULTS: Between-country analyses showed that log GDP was inversely correlated with exclusive (r = -0.37, P < 0.001) and continued breastfeeding (r = -0.74, P < 0.0001), and was positively correlated with formula intake (r = 0.70, P < 0.0001). Continued breastfeeding was inversely correlated with formula (r = -0.79, P < 0.0001), and was less strongly correlated with the intake of other types of nonhuman milk (r = -0.40, P < 0.001). Within-country analyses showed that 69 out of 89 did not have significant disparities in exclusive breastfeeding. Continued breastfeeding was significantly higher in children belonging to the poorest 20% of households compared with the wealthiest 20% in 40 countries (by ∼30 percentage points on average), whereas formula feeding was more common in the wealthiest group in 59 countries. CONCLUSIONS: BMS intake is positively associated with GDP and negatively associated with continued breastfeeding in LMICs. In most countries, BMS intake is positively associated with family wealth, and will likely become more widespread as countries develop. Urgent action is needed to protect, promote, and support breastfeeding in all income groups and to reduce the intake of BMS, in light of the hazards associated with their use.

RESUMEN

BACKGROUND: Enrolment in a research study requires the participant's informed consent. In the case of minors, informed consent of the respective legal guardian is obtained in conjunction with informed assent of the underage p articipant. Since comprehension of the information provided may be limited, effective interventions to improve understanding should be identified. Thus, it is the objective of this study to review quantitative studies that tested interventions to improve the understanding of information provided during assent processes in health research. The studied population consisted of minors that participated or were willing to participate in research. The primary outcome was the level of comprehension after intervention. METHODS: A systematic search was conducted in eleven databases including regional databases: PubMed, Web of Science, ERIC, PsycINFO, CINAHL, POPLINE, AIM, LILACS, WPRIM, IMSEAR, and IMEMR and included references from inception of the database until July 2018 except PubMed which spanned the period from May 2013 to July 2018. Search terms focused on Informed Consent/Assent, Minors, and Comprehension. To complement the search, reference lists of retrieved publications were additionally searched. We included all quantitative studies that were conducted in minors, tested an intervention, covered assent processes in health research, and assessed comprehension. One reviewer screened titles, abstracts, and full-texts to determine eligibility and collected data on study design, population, intervention, methods, outcome, and for critical appraisal. Interventions comprised enhanced paper forms, interspersed questions, multimedia format, and others. RESULTS: Out of 7089 studies initially identified, 19 studies comprising 2805 participants and conducted in seven countries were included in the review. Fourteen studies (74 %) tested an intervention against control and ten (53 %) were randomized controlled trials. Heterogeneous methodology as well as incomplete outcome and statistical reporting impaired the reliability of the collected data. Positive effects were suggested for use of enhanced paper forms, interspersed questions, use of pie charts, and organizational factors. CONCLUSIONS: Improving assent in health research is an under-researched area with little reliable evidence. While some interventions are proposed to improve understanding in assent processes, further investigation is necessary to be able to give evidence-based recommendations.

RESUMEN

BACKGROUND: In South Africa almost 2 million women work informally. Informal work is characterised by poor job security, low earnings, and unsafe working conditions, with high rates of poverty and food insecurity. The peripartum period is a vulnerable time for many working women. This study explored how mothers navigate the tension between the need to work and the need to take care of a newborn baby, and how this affects their feeding plans and practices. METHODS: A mixed methods longitudinal cohort method was employed. Informal workers were recruited in the last trimester of pregnancy during an antenatal visit at two clinics in Durban, South Africa. Data were collected using in-depth interviews and quantitative questionnaires at three time points: pre-delivery, post-delivery and after returning to work. Framework analysis was used to analyse qualitative data in NVIVO v12.4. Quantitative analysis used SPSSv26. RESULTS: Twenty-four participants were enrolled and followed-up for a period of up to 1 year. Informal occupations included domestic work, home-based work, informal trading, and hairdressing, and most women earned

RESUMEN

Breastfeeding education and support are critical health worker skills. Confusion surrounding infant feeding advice linked to the HIV epidemic has reduced the confidence of health workers to support breastfeeding. High antiretroviral therapy coverage of breastfeeding women living with HIV, and an Infant Feeding policy supportive of breastfeeding, now provides an opportunity to improve breastfeeding practices. Challenges remain in restoring health worker confidence to support breastfeeding. This qualitative study presents findings from focus group discussions with mothers of young infants, exploring their experiences of health worker breastfeeding counselling and support. Analysis followed the thematic framework approach. Six researchers reviewed the transcripts, coded them independently, then jointly reviewed the codes, and agreed on a working analytical framework. Although mothers received antenatal breastfeeding messages, these appeared to focus rigidly on the importance of exclusivity. Mothers described receiving some practical support with initiation of breastfeeding after delivery, but support and advice for post-natal breastfeeding challenges were often incorrect or absent. The support also ignored the context in which women make infant feeding decisions, including returning to work and pressures from family members. Despite improved breastfeeding policies, restoring confidence in health workers to support breastfeeding remains a challenge. The post-natal period, when mothers experience breastfeeding difficulties, is particularly critical, and our findings reinforce the importance of continuity of care between communities and health facilities. This research has implications for how health workers are trained to support breastfeeding. Greater attention is needed on developing skills and confidence in identifying, assessing, and supporting women experiencing breastfeeding challenges.

RESUMEN

Clinical guidelines are used to translate research findings into evidence-based clinical practice but are frequently not comprehensively adopted by health workers (HWs). HIV and infant feeding guidelines were revised by the World Health Organization to align feeding advice for HIV-exposed and unexposed infants, and these were adopted in South Africa in 2017. We describe an innovative, team-based, mentoring programme developed to update HWs on these guidelines. The intervention was underpinned by strong theoretical frameworks and aimed to improve HWs' attitudes, knowledge, confidence, and skills about breastfeeding in the context of HIV. On-site workshops and clinical mentoring used interactive participatory methods and a simple low-tech approach, guided by participants' self-reported knowledge gaps. Workshops were conducted at 24 participating clinics over three sessions, each lasting 1-2 hr. Evaluation data were collected using a self-administered questionnaire. Of 303 participating HWs, 249/303 (82.2%) attended all workshops. Achieving high workshop attendance was challenging and "catch-up" sessions were required to achieve good coverage. Common knowledge gaps identified included antiretroviral therapy adherence monitoring during breastfeeding and management of viral load results (173 participants), management of breast conditions (79), and advice about expressing and storing breastmilk (64). Most participants reported all their knowledge gaps were addressed and anticipated that their practice would change. We describe a feasible, sustainable approach to updating HWs on HIV and infant feeding guidelines and improving skills in breastfeeding counselling in resource-constrained settings. This approach could be adapted to other topics and, with further evaluation, implemented at scale using existing resources.

RESUMEN

BACKGROUND: Although women working in the informal economy are a large and vulnerable group, little is known about infant feeding and childcare practices among these women. The aim of this study was to explore childcare practices among mothers in informal work. METHODS: A cross-sectional survey among mothers with children aged < 2 years working in the informal economy in an urban and a rural site in KwaZulu-Natal, South Africa. Participants were selected using purposive and snowball sampling. RESULTS: A total of 247 interviews were conducted with 170 informal traders and 77 domestic workers. Most mothers lived with their child (225/247, 91.1%), had initiated breastfeeding (208/247; 84.2%) and many were still breastfeeding (112/247; 45.3%). Among 96 mothers who had stopped breastfeeding, the most common reason was returning to work (34/96; 35.4%). Many mothers relied on family members, particularly grandmothers, to care for their child while they were working (103/247, 41.7%) but some mothers took their child with them to work (70/247; 28.1%). Few fathers participated in the care of their child: 54 mothers (21.9%) reported that the father had ever looked after the child while she was away from home. Domestic workers were less likely than informal traders to take their child to work (p = 0.038). Women reported receiving a salary from an informal employer (119), or being own-account workers (120) or being unpaid/paid in kind (8). Most participants were in stable work (> 4 years) with regular working hours, but received very low pay. Domestic workers were more likely than informal traders to have regular working hours (p = 0.004), and to be earning >$240 per month (p = 0.003). Mothers reported high levels of food insecurity for themselves and their child: 153 mothers (61.9%) reported having missed a meal in the past month due to lack of resources to buy food, and 88 (35.6%) mothers reported that their child had missed a meal for this reason. CONCLUSION: This study provides a preliminary description of informal women workers who, despite having stable work, are vulnerable, low paid and food insecure. These women may require support to provide optimal childcare and nutrition for their children.

RESUMEN

Breastfeeding is one of the foundations of child health, development and survival. Breastmilk substitutes (BMS) are associated with negative influences on breastfeeding practices and subsequent health concerns and, as with all foods, production and consumption of BMS comes with an environmental cost. The carbon footprint (CFP) of production and consumption of BMS was estimated in this study. To illustrate regional differences among the largest producers and consumers, the CFP of BMS production in New Zealand, United States (USA), Brazil and France and the CFP of BMS consumption in United Kingdom (UK), China, Brazil and Vietnam were assessed. The CFP values were then compared with the CFP of breastfeeding arising from production of the additional food needed for breastfeeding mothers to maintain energy balance (approximately 500 kcal per day). The CFP of production was estimated to be 9.2 ±â€¯1.4, 7.0 ±â€¯1.0, 11 ±â€¯2 and 8.4 ±â€¯1.3 kg CO2e per kg BMS in New Zealand, USA, Brazil and France, respectively, with the largest contribution (68-82% of the total) coming from production of raw milk. The CFP of consumption, which included BMS production, emissions from transport, production and in-home sterilisation of bottles, and preparation of BMS, was estimated to be 11 ±â€¯1, 14 ±â€¯2, 14 ±â€¯2 and 11 ±â€¯1 kg CO2e per kg BMS in UK, China, Brazil and Vietnam, respectively. Comparison of breastfeeding with feeding BMS showed a lower CFP from breastfeeding in all countries studied. However, the results were sensitive to the method used to allocate emissions from raw milk production on different dairy processing co-products (i.e. BMS, cream, cheese and lactose). Using alternative allocation methods still resulted in lower CFP from breastfeeding, but only slightly for UK, Brazil and Vietnam. Care is also needed when interpreting findings about products that are functionally different as regards child health and development.

RESUMEN

Background: Human immunodeficiency virus (HIV)-infected pregnant women increasingly receive antiretroviral therapy (ART) to prevent mother-to-child transmission (PMTCT). Studies suggest HIV-exposed uninfected (HEU) children face higher mortality than HIV-unexposed children, but most evidence relates to the pre-ART era, breastfeeding of limited duration, and considerable maternal mortality. Maternal ART and prolonged breastfeeding while on ART may improve survival, although this has not been reliably quantified. Methods: Individual data on 19 219 HEU children from 21 PMTCT trials/cohorts undertaken from 1995 to 2015 in Africa and Asia were pooled to estimate the association between 24-month mortality and maternal/infant factors, using random-effects Cox proportional hazards models. Adjusted attributable fractions of risks computed using the predict function in the R package "frailtypack" were used to estimate the relative contribution of risk factors to overall mortality. Results: Cumulative incidence of death was 5.5% (95% confidence interval, 5.1-5.9) by age 24 months. Low birth weight (LBW <2500 g, adjusted hazard ratio (aHR, 2.9), no breastfeeding (aHR, 2.5), and maternal death (aHR, 11.1) were significantly associated with increased mortality. Maternal ART (aHR, 0.5) was significantly associated with lower mortality. At the population level, LBW accounted for 16.2% of 24-month mortality, never breastfeeding for 10.8%, mother not receiving ART for 45.6%, and maternal death for 4.3%; combined, these factors explained 63.6% of deaths by age 24 months. Conclusions: Survival of HEU children could be substantially improved if public health practices provided all HIV-infected mothers with ART and supported optimal infant feeding and care for LBW neonates.
