[Digital marketing of commercial infant formula in Argentina: a digital ethnographic study]. / Marketing digital de fórmulas comerciales infantiles en Argentina: un estudio etnográfico digital.

Although evidence of the benefits of breastfeeding is widespread, there are several challenges to initiate and sustain it. Infant formula companies use marketing strategies that violate existing regulations, contributing to its early abandonment. We explore the digital marketing exposure of infant formulas in Argentina by analyzing people's interactions with brands and the traces of these interactions in conversations engaged in Facebook groups during 2022, from a qualitative approach based on digital ethnography. Results show that companies deploy regulatory avoidance tactics and seek contact with mothers. Users do not interact with the accounts but are exposed to their strategies given the correlation between product attributes present in advertising with their motivations and aspirations. The mediators between marketing and mothers are medical professionals, used as marketing resources. We conclude that authorities should promote new agreements on the practices of medical professionals and develop regulations taking into account digital environments.

Si bien es extendida la evidencia de los beneficios de la lactancia materna, diversos son los desafíos para iniciarla y sostenerla. Las empresas productoras de fórmulas infantiles utilizan estrategias de marketing violatorias de las regulaciones existentes, contribuyendo a su temprano abandono. Exploramos la exposición al marketing digital de las fórmulas infantiles en Argentina mediante el análisis de las interacciones de la población con las marcas y las huellas de dichas interacciones en conversaciones entabladas en grupos de Facebook durante 2022, desde un enfoque cualitativo basado en la etnografía digital. Los resultados muestran que las empresas despliegan tácticas elusivas de las regulaciones y buscan el contacto con las madres. Las usuarias no interactúan con las cuentas, pero están expuestas a sus estrategias dado el correlato entre los atributos del producto presentes en la publicidad con sus motivaciones y aspiraciones. Los mediadores entre el marketing y las madres son los profesionales médicos, utilizados como recursos del marketing. Concluimos que las autoridades deben promover nuevos acuerdos sobre las prácticas de los profesionales médicos y desarrollar regulaciones teniendo en cuenta los entornos digitales.

Breastfeeding, first-food systems and corporate power: a case study on the market and political practices of the transnational baby food industry in Brazil.

BACKGROUND: The exploitative marketing of commercial milk formula (CMF) reduces breastfeeding, and harms child and maternal health globally. Yet forty years after the International Code of Marketing of Breast-Milk Substitutes (The Code) was adopted by WHO member states, many countries are still to fully implement its provisions into national law. Furthermore, despite The Code, worldwide CMF markets have markedly expanded. In this paper, we adopt Brazil as a case study to understand the power of the baby food industry's marketing and corporate political activity, and how this influences the country's 'first-food system' in ways that promote and sustain CMF consumption. METHODS: We used a case study design, drawing data from from documents and key informant interviews (N = 10). RESULTS: Breastfeeding rates plummeted in Brazil to a historic low in the 1970s. A resurgence in breastfeeding from the mid-1980s onwards reflected strengthening political commitment for a national policy framework and breastfeeding protection law, resulting in-turn, from collective actions by breastfeeding coalitions, advocates, and mothers. Yet more recently, improvements in breastfeeding have plateaued in Brazil, while the industry grew CMF sales in Brazil by 750% between 2006 and 20. As regulations tightened, the industry has more aggressively promoted CMF for older infants and young children, as well as specialised formulas. The baby food industry is empowered through association with powerful industry groups, and employs lobbyists with good access to policymakers. The industry has captured the pediatric profession in Brazil through its long-standing association with the Brazilian Society of Pediatrics. CONCLUSION: Brazil illustrates how the baby food industry uses marketing and political activity to promote and sustain CMF markets, to the detriment of breastfeeding. Our results demonstrate that this industry requires much greater scrutiny by regulators.

A qualitative analysis of the breastfeeding experiences of mothers who are nurses and nutritionists.

BACKGROUND: From a medical standpoint, breastmilk is the optimal option for feeding a baby, relegating the cultural, social, and material determinants to breastfeeding. Worldwide, breastfeeding rates are low, especially among working mothers. Healthcare providers have low breastfeeding rates due to several barriers to lactation, i.e. work schedule andlack of private places for pumping. METHOD: A descriptive qualitative methodology was applied to examine the breastfeeding experiences of Ecuadorian mothers who are healthcare professionals. Twenty healthcare professionals who breastfed their babies took part in the research. Data gathering employed synchronous semi-structured interviews in Spanish. The data analysis followed the Phronetic Iterative Approach. RESULTS: Women shifted the preconceived idea of the ideal breastfeeding scenario concerning duration, promotion, and support, ideals which are constructed in their training as healthcare professionals. Although these women believe that breast milk and breastfeeding is the best way to feed a baby, the internalized ideal of breastfeeding shifted with the experience of motherhood. Although they had that clash between the ideal and the external reality, they continued breastfeeding their babies, and those experiences resulted in them improving their professional practice. CONCLUSIONS: This study demonstrated that breastfeeding for this group of women appears to be a unique relational and identity negotiation process. The findings emphasize that experiencing breastfeeding for this group of healthcare providers positively shifted how they communicate breastfeeding with their patients in the clinical encounter. Ensuring that healthcare professionals acquire a different approach for educating and communicating about lactation is an essential determinant in efforts to improve breastfeeding rates in Ecuador.

Avaliação da composição nutricional do composto lácteo à venda no mercado brasileiro / Evaluation of the nutritional composition of growing-up milk available in the Brazilian market

Introdução: A influência do consumo de composto lácteo na nutrição de crianças em primeira infância ainda é desconhecida, apesar de o produto movimentar um mercado multimilionário. Objetivo: Avaliar a composição nutricional do composto lácteo e a influência de seu consumo sobre as necessidades diárias de macronutrientes e energia de crianças pequenas. Métodos: A pesquisa foi dividida em três partes, sendo: a) avaliação da composição nutricional e ingredientes; b) comparação do composto lácteo brasileiro com uma proposta de padronização; c) cálculo de inadequação nutricional e influência do consumo de composto lácteo em crianças pequenas. Resultados: Foi possível categorizar o produto em três subgrupos, de acordo com os ingredientes, sendo: grupo 1 (soro de leite, açúcar e gordura vegetal), grupo 2 (adição de vitaminas e minerais) e grupo 3 (ampla lista de ingredientes, sem adição de açúcares e adição de bioativos). De forma geral, o composto lácteo tem como características: excesso de proteínas e açúcares de adição, predominância de gorduras saturadas, além de aditivos químicos. Em comparação com a proposta de composição ideal, o composto lácteo brasileiro excede todos os nutrientes analisados e, por fim, o consumo de dois copos de 200mL de composto lácteo por dia corresponde a 100% das necessidades diárias de proteína, sendo as crianças de 0 a 11 meses as mais prejudicadas. Conclusão: Independentemente do subgrupo e do ingrediente, o produto tem impacto negativo na saúde infantil, e quanto menor a idade de introdução, maior o impacto na saúde, podendo levar ao desenvolvimento de sobrepeso e obesidade.

Introduction: The influence of consuming growing-up milk on the nutrition of infants is still unknown, despite the product driving a multimillion-dollar market. Objective: To evaluate the nutritional composition of the growing-up milk and the influence of its consumption on the daily macronutrient and energy needs of young children. Methods: The research was divided into three parts, namely: a) evaluation of nutritional composition and ingredients; b) comparison of the Brazilian growing-up milk with a proposed standardization; c) calculation of nutritional inadequacy and the influence of growing-up milk consumption in young children. Results: It was possible to categorize the product into three subgroups based on ingredients, namely: group 1 (whey, sugar, and vegetable fat), group 2 (added vitamins and minerals), and group 3 (a wide range of ingredients, no added sugars, and addition of bioactives). Overall, the growing-up milk is characterized by excess protein and added sugars, a predominance of saturated fats, and the presence of chemical additives. Compared to the proposed ideal composition, the Brazilian growing-up milk exceeds all analyzed nutrients. Finally, consuming two 200mL glasses of growing-up milk per day corresponds to 100% of daily protein needs, with children aged 0 to 11 months being the most affected. Conclusion: Regardless of the subgroup and ingredient, the product has a negative impact on children's health, and the younger the age of introduction, the greater the impact on health, potentially leading to the development of overweight and obesity.

Quality control of psychoactive substances in human breastmilk samples from a human milk bank by disposable pipette extraction-gas chromatography-mass spectrometry.

The lack of data regarding infant exposure to drugs of abuse consumed by lactating mothers has become a major health concern. Investigating psychoactive substances and their metabolites in breastmilk is an analytical approach to estimate the rate at which drugs of abuse are excreted and how much infants are exposed to them. In this study, we have developed and validated a GC-MS method using disposable pipette tips for simultaneously extracting ten analytes from breastmilk samples obtained from a milk bank in the city of Ribeirão Preto, Brazil. All the 67 analyzed samples tested negative for all the analytes. This is the first study that has applied disposable pipette extraction to analyze drugs of abuse in breastmilk samples.

Breastfeeding, the most effective single strategy to reduce child mortality, provides numerous benefits for both the mother and the infant. The mother's consumption habits during breastfeeding strongly influence breastmilk quality and the newborn's nutrition. Given that drugs of abuse negatively affect both the mother's and the infant's health, analyzing breastmilk samples helps to estimate infant exposure to these drugs and to evaluate how severe this public health issue is. We have developed a new method to monitor ten substances in breastmilk, to improve our understanding of this issue in Brazil. None of the substances were detected in the few samples obtained from a milk bank, which showed that this organization successfully analyzes the donor's profile and conducts effective anamnesis. Future analysis of a larger number of samples and hence more data could help to describe the current scenario in more detail.

The Idealization of Infant Formula: A Longitudinal Analysis of Labels in Uruguay.

BACKGROUND: Labels are a key element of the marketing strategies of infant formula companies, and often include text or images that idealize their use, undermining efforts to promote breastfeeding. RESEARCH AIMS: To evaluate the prevalence of marketing cues that idealize infant formula on labels of products commercialized in Uruguay and to assess changes after a periodic monitoring of compliance with the International Code of Marketing of Breast-Milk Substitutes (IC). METHOD: This study is a descriptive, observational, and longitudinal assessment of the information included on infant formula labels. The first data collection was in 2019, as part of a periodic assessment to monitor the marketing of human-milk substitutes. In 2021, the same products were purchased to evaluate changes in their labels. Thirty-eight products were identified in 2019, of which 33 were still available in 2021. All information available on the labels was analyzed through content analysis. RESULTS: Most products included at least one textual or visual marketing cue idealizing infant formula in both 2019 (n = 30, 91%) and 2021 (n = 29, 88%). This represents a violation of both the IC and national regulations. References to nutritional composition were the most frequent marketing cue, followed by references to child growth and development. No relevant changes were observed after the periodic assessment conducted by the Uruguayan government. CONCLUSIONS: Monitoring compliance with the IC per se cannot be expected to trigger changes in the marketing strategies of infant formula companies. More explicit regulations and strong enforcement mechanisms are needed to end the inappropriate marketing practices on infant formula labels.

Improving Early Colostrum Administration to Very Low Birth Weight Infants in a Level 3 Neonatal Intensive Care Unit: A Quality Improvement Initiative.

OBJECTIVE: To improve our human milk practices by increasing early and sustained use of colostrum as oral immune therapy (OIT) in very low birthweight (VLBW) infants admitted at a level 3 neonatal intensive care unit. STUDY DESIGN: Using the Institute for Healthcare Improvement's Model for Improvement, several interventions aimed at increasing early OIT administration were implemented. Four key drivers included: optimizing evidence-based OIT guidelines, personnel alignment and engagement, optimal electronic health record use for ordering practices, and timely lactation consultant involvement. The primary outcome measure was early OIT administration, whereas secondary outcome measures examined all OIT administration and human milk at discharge. Process measures included the percentage of staff members who were compliant with OIT protocol. RESULTS: Early OIT administration increased from a baseline mean of 6% to 55% in the 12-month study period. Percentage of total (early and late) OIT administration to VLBW infants increased from a baseline of 21% to 85%. Average human milk at discharge for VLBW infants remained at 44%, without significant improvement. CONCLUSIONS: A multidisciplinary quality improvement initiative led to significant improvement in OIT administration to infants at a level 3 neonatal intensive care unit.

Digital marketing of commercial breastmilk substitutes and baby foods: strategies, and recommendations for its regulation in Mexico.

BACKGROUND: Parents are exposed to breastmilk substitutes and baby foods marketing on the internet and social media, which hinders adequate breastfeeding and complementary feeding. This study identifies digital marketing strategies for breastmilk substitutes, specifically commercial milk formula and baby foods used by the industry to influence infant and young children's feeding practices in Mexico and proposes regulatory recommendations that can be useful for similar countries. METHODS: Qualitative study based on the CLICK monitoring framework developed by the World Health Organization, adapted for digital marketing of commercial milk formula and baby foods. Semi-structured interviews (n = 53) with key actors were conducted between November 2020 and March 2021, and used grounded theory for the analysis and interpretation with the MAXQDA 20 software. RESULTS: Commercial milk formula and baby food companies use digital media to contact and persuade parents to use their products by sending electronic newsletters with advertising. Companies hire influencers to market their products because there is no regulation prohibiting the advertisement of breastmilk substitutes on social media, and promote formula among health professionals inviting them to participate in sponsored webinars on infant nutrition, ignoring conflict of interest and the International Code of Marketing of Breastmilk Substitutes. Parents trust formula and baby food advertisements, which use emotional messages and health and nutrition claims to encourage their consumption. Health professionals consider that claims contribute to the indiscriminate use of formula, and some actors propose the use of plain packaging for these products. CONCLUSIONS: Breastmilk substitutes companies promote their products in digital media using unethical strategies that fail to comply with the International Code of Marketing of Breastmilk Substitutes. They generate strong conflicts of interest with health professionals, taking advantage of legal framework gaps and the lack of monitoring and effective sanctions for non-compliers. Updating the legal framework and monitoring compliance, including digital media, is urgently needed to protect children's right to breastfeeding, healthy nutrition and life, and the rights of women to health and informed decision-making.

[Microbiota in food allergy: prebiotics, probiotics and synbiotics]. / Microbiota en alergia alimentaria: prebióticos, probióticos y simbióticos.

The close relationship between the microbiota and allergic diseases has been known for several years, particularly food allergy. Although the best studied microbiota is that related to bacteria, viruses, parasites and fungi are also constituents of this, although their role is not definitively clarified. The microbial world interacts with the human body constantly, we are in daily contact with an infinite and innumerable number of varieties of microbes in our environment, some of them can pass through the body without causing any harm, while others generate undesirable risk for the body. health. Alteration of the original composition of the microbiota (dysbiosis) is associated with food allergy. This dysbiosis is related to changes in habits, method of termination of pregnancy (birth or cesarean section), replacement of breastfeeding or interruption at an early age; decrease in family size; loss of contact with farm animals or pets; inappropriate prescription or abuse of antibiotics. The transition from a diet based exclusively on milk to one with solid foods is associated with a drastic increase in microbial diversity. Immunomodulatory components of the microbiota (cell surface polysaccharides), dietary factors (vitamin A), and production of secondary metabolites (short-chain fatty acids and secondary bile acid metabolites) promote differentiation of the RORγt+ cell population Treg. ILC3 produces IL-2, which plays a decisive role in maintaining intestinal homeostasis.

La estrecha relación entre la microbiota y las enfermedades alérgicas es conocida desde hace varios años, particularmente la alergia alimentaria. Aunque la microbiota mejor estudiada es la relacionada con las bacterias, también son constitutivas de esta los virus, parásitos y hongos, aun con un rol no definitivamente esclarecido. El mundo microbiano interactúa con el cuerpo humano constantemente, estamos en contacto diario con una cantidad infinita e innumerable de variedades de microbios en nuestro entorno, algunos de ellos pueden pasar a través del cuerpo sin causar ningún daño, mientras que otros generan riesgo indeseable para la salud. La alteración de la composición original de la microbiota (disbiosis) se asocia con alergia alimentaria. Esta disbiosis se relaciona con los cambios de hábito, vía de finalización del embarazo (parto o cesárea), sustitución de la lactancia o interrupción en edades tempranas; disminución del tamaño de las familias; pérdida de contacto con animales de granja o mascotas; prescripción inadecuada o abuso de antibióticos. La transición de una dieta basada exclusivamente en leche a otra con alimentos sólidos se asocia con aumento drástico en la diversidad microbiana. Los componentes inmunomoduladores de la microbiota (polisacáridos de la superficie celular), los factores dietéticos (vitamina A) y la producción de metabolitos secundarios (ácidos grasos de cadena corta y metabolitos secundarios de ácidos biliares) promueven la diferenciación de la población de células RORγt + Treg. La ILC3 produce IL-2, que desempeña un papel decisivo en el mantenimiento de la homeostasis intestinal.

Violations in the marketing of milks and complementary foods that compete with breastfeeding in Rio de Janeiro City, Brazil / Infrações na comercialização de leites e alimentos de transição que competem com o aleitamento materno na cidade do Rio de Janeiro

ABSTRACT Objective: To analyze if milk and complementary foods are being sold under the Brazilian Code of Marketing of Infant and Toddler's Food, Teats, Pacifiers and Baby Bottles (NBCAL), Law 11265/2006 of breastfeeding protection. Methods: Epidemiological survey that analyzed the marketing practices of pharmacies, supermarkets, and department stores in the Southern region of the city of Rio de Janeiro, Brazil, by direct observation. Results: Among the 349 stores in Rio de Janeiro's South Region, 339 traded milk and complementary foods and, among them, 60.8% were not complying with NBCAL. Infractions to NBCAL were more common for the selling of milk (58.6%) than complementary foods (22.8%). The most recurrent promotion strategy infringing NBCAL was discount pricing without the Ministry of Health disclaimer. Conclusions: Most retail stores infringe NBCAL in the commercialization of milk and complementary foods in the city of Rio de Janeiro, Brazil, a violation of the right to information that may impact mothers' choice regarding their child's feeding.

RESUMO Objetivo: Analisar se leites e alimentos de transição estão sendo comercializados de acordo com a Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância, Mamadeiras, Bicos e Chupetas (NBCAL), Lei n. 11.265/2006, de proteção ao aleitamento materno. Métodos: Inquérito epidemiológico que analisou as práticas de promoção comercial de leites e alimentos de transição em um censo de farmácias, supermercados e lojas de departamento da Zona Sul da cidade do Rio de Janeiro, por meio de observação direta. Resultados: Dos 349 estabelecimentos da Zona Sul, 339 comercializavam leites e alimentos de transição e, destes, 60,8% faziam promoção comercial em desacordo com a NBCAL. Mais da metade dos estabelecimentos (58,6%) tinha leites e 22,8%, alimentos de transição vendidos em inconformidade com a NBCAL. A estratégia de promoção comercial mais praticada foi o desconto no preço sem a frase informativa preconizada pelo Ministério da Saúde. Conclusões: A maior parte dos estabelecimentos comerciais infringe a NBCAL na comercialização de leites e alimentos de transição, configurando uma violação ao direito à informação que pode impactar na escolha das mães quanto à alimentação de seus filhos.

Baby food industry interference with infant feeding international regulation-A case study on the standard for follow-up formula.

Introduction: Globally, first-food systems have changed and breastfeeding has decreased due to the increased growth in commercial breast milk substitute (BMS) consumption, which includes both follow-up and toddler formulas. These products are manufactured by a small number of corporate leaders in international BMS sales. Discussions for global regulation of these products take place in the Codex Alimentarius and are permeated by the strong participation of these corporations in the Codex committees. Objective: In the present study, the participation of the baby food industry in the review of the follow-up formula standard in the Codex Committee on Nutrition and Foods for Special Dietary Uses (CCNFSDU) was analyzed. Methods: The analysis of the CCNFSDU documents was based on the period from 2009 to 2019 and used quantitative and qualitative approaches. Compositional and participation data from country delegations and observer organizations on the representative profiles of the involved institutions and the baby food industry's involvement in this process were established systematically. Results: In total, 134 out of the 189 Codex Alimentarius member countries engaged in the standard review process, of which 28% were involved in the entire process. The private sector was present in 81% of the most assiduous member state delegations to the meetings. Furthermore, ~60% of the observer organizations involved in the review process were business associations representing industry interests. Moreover, the International Special Dietary Foods Industries was the only business association with observer status in the CCNFSDU that was specifically dedicated to representing the baby food industryduring the review process. Conclusion: These research results expand the body of evidence confirming the expressive and disproportionate participation of baby food industries and their representatives in the discussion processes within the scope of the CCNFSDU. However, studies investigating the Codex and the public documents of its respective committees are limited. Thus, this was the first study to analyze the influence of the baby food industry on BMS global regulatory compliance.

Anesthesia and breastfeeding / Lactancia materna y anestesia

Abstract The importance of breastfeeding with its positive impact on the wellbeing of the mother-infant pair is well established. Anesthesiologists should encourage the promotion of lactation by being willing to give reassurance during the preoperative period and preparing a plan that does not interfere with safe breastfeeding. There is concern regarding the transfer of drugs into breast milk, which may lead to inconsistent advice from many health professionals and to early discontinuation. However, evidence shows that most anesthetic drugs are safe in terms of transfer into breast milk, and hence, compatible with breastfeeding, which should be resumed after anesthesia as soon as the mother is alert and feels well enough to hold her infant, without the need to "pump and dump". This review provides pharmacokinetic information on commonly used anesthesia drugs and their passage into breast milk, to help practitioners discuss risks and benefits with the mother, emphasizing that anesthesia should not interfere with the benefits of breastfeeding. Four practical clinical scenarios are presented: pregnant women concerned about the effect of epidural analgesia on subsequent breastfeeding, spinal anesthesia for c-section and lactation, patients who will receive general anesthesia during cesarean section, and finally women who are breastfeeding and require anesthesia for elective or urgent surgery. Neuraxial anesthesia allows for better pain control and immediate skin-to-skin contact at the time of childbirth. Also, it interferes the least with the woman's ability to care for her infant. Regional techniques, opioid-sparing techniques and outpatient surgery are preferred. Drugs such as opioids and longer-acting benzodiazepines should be administered cautiously, particularly in repeat doses.

Resumen La lactancia materna tiene evidentes beneficios para el binomio maternofetal. El anestesiólogo debe ser un agente en la promoción de la lactancia, estar dispuesto a resolver dudas en el preoperatorio y elaborar un plan que no interfiera con su seguridad. Hay preocupación referente a la transferencia de los medicamentos (endovenosos y/o neuroaxiales) hacia la leche, que puede conducir a un consejo inconsistente de muchos profesionales de la salud, lo cual contribuye a la suspensión temprana de la lactancia materna. Sin embargo, existe evidencia de que la mayoría de los medicamentos que se utilizan en la anestesia (general y neuroaxial) son compatibles con la lactancia materna. Se debe iniciar la lactancia materna después de la anestesia tan pronto como la madre esté alerta y se sienta bien, sin necesidad de extraerla y eliminarla. Esta revisión entrega información farmacocinética sobre los medicamentos y técnicas anestésicas comúnmente utilizadas para que los profesionales realicen un balance riesgo-beneficio con la madre, enfatizando que la anestesia no debe interferir con los beneficios de la lactancia. Se presentan cuatro escenarios clínicos prácticos: embarazada preocupada por el efecto de la analgesia peridural en su lactancia posterior, anestesia raquídea para cesárea y efecto en lactancia, pacientes que requieren anestesia general para cesárea y, por último, paciente puérpera que requiere anestesia para cirugía. Las técnicas neuroaxiales permiten un mejor control del dolor y contacto piel con piel precoz en el parto vaginal o cesárea, lo que facilita que la madre inicie la lactancia más rápido. Si el escenario lo permite, se prefieren técnicas regionales, técnicas ahorradoras de opioides y cirugía ambulatoria, teniendo precaución con ciertos opioides y benzodiacepinas de acción larga especialmente ante dosis repetidas.

SARS-CoV-2-Specific IgG and IgA response in maternal blood and breastmilk of vaccinated naïve and convalescent lactating participants.

Background: Recent studies have shown the presence of SARS-CoV-2-specific antibodies in the milk of breastfeeding mothers vaccinated with mRNA and convalescent. However, limited information is available in lactating women receiving other vaccine platforms used in developing countries, such as the inactivated SARS-CoV-2 vaccine BBIBP-CorV (Sinopharm) and the non-replicating adenovirus vaccines Sputnik V (Gamaleya Institute) and ChAdOx1-S (Oxford AstraZeneca). Methods: Here, we evaluated anti-SARS-CoV-2 IgG and IgA levels in both serum and milk samples using a longitudinal and a cross-sectional cohort of 208 breastfeeding vaccinated women from Argentina with or without previous SARS-CoV-2 infection. Results: The analysis showed that IgA levels remain constant in serum and milk of breastfeeding mothers between the first and second doses of vector-based vaccines (Sputnik V and ChAdOx1-S). After the second dose, anti-spike IgA was found positive in 100% of the serum samples and in 66% of breastmilk samples. In addition, no significant differences in milk IgA levels were observed in participants receiving BBIBP-CorV, Sputnik V or ChAdOx1-S. IgG levels in milk increased after the second dose of vector-based vaccines. Paired longitudinal samples taken at 45 and 120 days after the second dose showed a decrease in milk IgG levels over time. Study of IgA levels in serum and milk of vaccinated naïve of infection and vaccinated-convalescent breastfeeding participants showed significantly higher levels in vaccinated-convalescent than in participants without previous infection. Conclusion: This study is relevant to understand the protection against SARS-CoV-2 by passive immunity in newborns and children who are not yet eligible to receive vaccination.

Methodologies for Monitoring the Digital Marketing of Foods and Beverages Aimed at Infants, Children, and Adolescents (ICA): A Scoping Review.

While television has been the most widely used medium for food and beverage marketing, companies are shifting in favor of digital media. The ubiquitous digital marketing of breast-milk substitutes (BMS) and foods and beverages high in saturated fat, salt, and/or free sugars (FBHFSS) has been considered a powerful environmental determinant of inadequate dietary practices during infancy, childhood, and adolescence. The scoping review's aim was to systematically identify and map the types of methodologies available to monitor the digital marketing of foods and beverages targeting infants, children, and adolescents (ICA) worldwide. Research evidence published from 2011 to October 2021 was examined using search strategies including multiple databases and citation tracking. A total of 420 sources were evaluated, and 28 studies from 81 countries meeting the inclusion criteria were retained. Most of the studies (n = 24) documenting methodologies to monitor inappropriate digital marketing were published since 2015 and were primarily aimed at identifying the promotional techniques and nutritional content of FBHFSS targeting adolescents (n = 13). It is paramount to develop a feasible and scalable monitoring system to develop effective policies to protect parents and ICA from BMS and FBHSFF digital marketing.

Infant Feeding Practices That Substitute Exclusive Breastfeeding in a Semi-Rural Mexican Community: Types, Moments, and Associated Factors.

International organizations recommend mothers practice exclusive breastfeeding (EBF) during the first six months of their infant's life and introduce complementary feeding (CF) thereafter while continuing breastfeeding. However, the earlier introduction of liquids and foods is common worldwide and may have negative effects on breastfeeding practice, nutrition, and health. In this formative cross-sectional study, we interviewed 143 mothers from semi-rural communities in Tabasco, Mexico, whose infants were 4-6 months old. We explored (1) which feeding practices substituted EBF and (2) which factors were associated with each practice. During the first month of life, 42.7% of infants received formula milk (FM); this proportion increased to 74.5% by the sixth month. Adjusted Poisson regression analyses showed that giving FM was positively related to working away from home (PR 1.27; 95% CI 1.06, 1.54) and the perception that FM is an important food to accompany breast milk (PR 1.38; 95% CI 1.19, 1.70). Giving FM was negatively associated with not being sure the infant is full after breastfeeding (PR 0.75; 95% CI 0.61, 0.92). Regarding CF, less than half (47.5%) of infants had not received it by the fifth month. Factors positively associated with timely CF introduction were: the mother was told during prenatal care visits the optimal age to start CF is 6 months (PR 1.17, 95% CI 1.06, 1.29); she is convinced that giving only breast milk is best for her baby (PR 1.15, 95% CI 1.03, 1.29), and a higher infant weight-for-length (PR 1.04, 95% CI 1.00, 1.08) and length for age (PR 1.04, 95% CI 1.00, 1.09) z-scores at the study visit; conversely, it was negatively associated to the idea that if the infant is not full, she/he should receive formula milk or some other food (PR 0.87, 95% CI 0.78, 0.96). In these communities, EBF is lost to the use of FM and early CF. The factors associated with these inadequate feeding practices are related to returning to work, information received during prenatal visits, and the mother's beliefs and thoughts. This work will guide the design of an intervention on infant feeding practices for these communities and other similar ones.

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.

Follow-up and growing-up formula promotion among Mexican pregnant women and mothers of children under 18 months old.

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.

Exposure to marketing of breastmilk substitutes in Mexican women: Sources and scope.

BACKGROUND: Aggressive and unregulated marketing of breastmilk substitutes (BMS) results in increased child morbidity and mortality. Unregulated BMS marketing is a major public health concern because it encourages formula consumption at the expense of breastfeeding. This study aimed to identify the sources and characterize the nature of exposure to marketing of BMS among Mexican mothers of children under 18 months of age. As a secondary objective we explored potential association between exposure to BMS marketing and infant feeding practices. METHODS: Cross-sectional study, comprising a pre-piloted survey, was conducted between February 2020 to February 2021 with Mexican mothers of children under 18 months of age (n = 754), in two major cities in Mexico. Mothers were selected according to their current infant feeding practices (Breastfeeding only vs. Mixed feeding). We characterized the different BMS marketing sources and scope, and related them with infant feeding practices. In addition, we used logistic regression models to estimate the odds ratio for infant feeding practices by BMS marketing exposure or recommendation. RESULTS: Mothers reported different sources of exposure to BMS promotion, including BMS advertisements in diverse media channels (41.6%), recommendation by a healthcare professional and/or relative (76.2%), and receiving a BMS sample at a hospital (18.6%). By contrast, only 36.5% recalled hearing or seeing breastfeeding information the previous year. The odds of mixed feeding were substantially higher, compared to breastfeeding, when mothers were recommended to use a BMS by doctors/pediatricians (OR: 3.96, 95% CI: 2.00, 7.83). Having seen or heard breastfeeding information in the previous year was associated with a lower risk of mixed feeding compared to breastfeeding only (OR: 0.59, 95% CI: 0.35, 0.99). CONCLUSIONS: Mexican mothers of young children in the metropolitan areas studied were highly exposed to BMS marketing and through different mass media channels and inter-personal sources. Health care professionals, particularly doctors/pediatricians, are a source of BMS promotion that are likely to have a strong influence on maternal decisions about infant feeding practices. There is an urgent need to protect mothers and their families against unregulated BMS promotion through mass media channels and directly by influential individuals, including health care providers.
