Abstract
The method of infant feeding has consequences for the production of greenhouse gases (GHG) as well as for the risks to infants posed by climate change. Breastfeeding can reduce the carbon footprint associated with the use of commercial infant formula by nearly 50% while reducing its water footprint and waste. It is also an excellent way of coping with emergencies associated with climate change, such as water shortages, since breastfed children are better protected than those fed with formula. To ensure that the protection offered by breastfeeding can be realized, we present elements that can help decision-makers seize a promising opportunity: improve infant feeding support for women and families.

Abstract
BACKGROUND Disparities in breastfeeding rates and exclusivity exist across regions and countries despite multifaceted breastfeeding promotion efforts in recent decades. Markets for artificial milk formula continue to grow as its substitution for breastfeeding is common. A new approach is needed for breastfeeding promotion strategies. RESEARCH AIM This state-of-the-art review aimed to describe the implications of not-breastfeeding on the environment within the context of food system sustainability. METHOD A total of 19 peer-reviewed articles within a 20-year timeframe were included in this review. Authors searched five databases for articles including Science Direct, GreenFILE, Springer Link, ProQuest, and PubMed. RESULTS The demand for artificial milk formula production as a replacement for breastfeeding results in increased greenhouse gas emissions, water pollution, and waste, thereby aggravating problems with freshwater scarcity. A short duration of breastfeeding and limited exclusivity have been associated with close birth spacing and contributing to global population growth. Breastfeeding is a healthy, sustainable diet, and a culturally acceptable first food. It advances health equity and food security. Exclusive breastfeeding for the first 6 months of life can be promoted with emphasis on total carbon footprint reduction, prevention of waterway degradation, and natural birth spacing, thereby sustaining food systems at large. CONCLUSION It is important to reform food, nutrition, and environmental policies to protect exclusive breastfeeding while decarbonizing artificial milk formula production. More research is needed to provide directions for new breastfeeding promotion strategies connecting breastfeeding with environmental stewardship.

Abstract
Human infants are born to breastfeed. While 50% of lactating persons struggle to make enough milk, there are no governmentally-approved drugs to enhance lactation1. Here, we engineer a variant of the naturally-occurring driver of lactation, the hormone Prolactin, to increase its serum half-life and produce a viable drug candidate. Our engineered variant, Prolactin-eXtra Long-acting (Prolactin-XL), is comprised of endogenously active human prolactin fused to an engineered human IgG Fc domain designed to overcome the unique drug development challenges specific to the lactating person-infant dyad. Our Prolactin-XL has a serum half-life of 70.9h in mice, 2,625-fold longer than endogenously active prolactin alone (70.9h v. 0.027h). We demonstrate that Prolactin-XL increases milk production and restores growth of pups fed by dams with pharmacologically-ablated lactation. We show that Prolactin-XL-enhanced lactation is accompanied by reversible, lactocyte-driven changes in mammary gland morphology. This work establishes long-acting prolactins as a potentially powerful pharmacologic means to combat insufficient lactation.

Abstract
The powdered formula market is large and growing, with sales and manufacturing increasing by 120% between 2012 and 2021. With this growing market, there must come an increasing emphasis on maintaining a high standard of hygiene to ensure a safe product. In particular, Cronobacter species pose a risk to public health through their potential to cause severe illness in susceptible infants who consume contaminated powdered infant formula (PIF). Assessment of this risk is dependent on determining prevalence in PIF-producing factories, which can be challenging to measure with the heterogeneity observed in the design of built process facilities. There is also a potential risk of bacterial growth occurring during rehydration, given the observed persistence of Cronobacter in desiccated conditions. In addition, novel detection methods are emerging to effectively track and monitor Cronobacter species across the food chain. This review will explore the different vehicles that lead to Cronobacter species' environmental persistence in the food production environment, as well as their pathogenicity, detection methods and the regulatory framework surrounding PIF manufacturing that ensures a safe product for the global consumer.

Abstract
The World Breastfeeding Trends Initiative (WBTi) provides a participative framework to bridge the gaps in policies and programs on breastfeeding. This concurrent mixed-methods study investigated how and why carrying out WBTi evaluations in countries influences their breastfeeding policies and outcomes. We used data from WBTi's Global Repository to evaluate performance scores in 98 countries and conducted semi-structured in-depth interviews to investigate the impact of WBTi process, using the Managing for Development Results structure and actor-network theory. Countries that conducted WBTi multiple times seem to have better breastfeeding policies and practices than countries that have assessed only once. The central feature of the process and its subsequent impact is the dialectical interaction between the technical and political elements of the WBTi exercise. We believe that WBTi's framework is a promising monitoring and evaluation tool that could be used to engage dialogue in other public health areas.

Abstract
Young children have unique nutritional requirements, and breastfeeding is the best option to support healthy growth and development. Concerns have been raised around the increasing use of milk-based infant formulas in replacement of breastfeeding, in regards to health, social, economic and environmental factors. However, literature on the environmental impact of infant formula feeding and breastfeeding is scarce. In this study we estimated the environmental impact of four months exclusive feeding with infant formula compared to four months exclusive breastfeeding in a Norwegian setting. We used life-cycle assessment (LCA) methodology, including the impact categories global warming potential, terrestrial acidification, marine and freshwater eutrophication, and land use. We found that the environmental impact of four months exclusive feeding with infant formula was 35–72% higher than that of four months exclusive breastfeeding, depending on the impact category. For infant formula, cow milk was the main contributor to total score for all impact categories. The environmental impact of breastfeeding was dependant on the composition of the lactating mother’s diet. In conclusion, we found that breastfeeding has a lower environmental impact than feeding with infant formula. A limitation of the study is the use of secondary LCA data for raw ingredients and processes.

Risk factors for self‐reported insufficient milk during the first 6 months of life: A systematic review. MATERNAL & CHILD NUTRITION 2022; 18 Suppl 3:e13353. [PMID: 35343065 PMCID: PMC9113468 DOI: 10.1111/mcn.13353] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 02/17/2022] [Accepted: 02/21/2022] [Indexed: 12/22/2022]
Abstract
The objective of this systematic review was to identify multifactorial risk factors for self‐reported insufficient milk (SRIM) and delayed onset of lactation (DOL). The review protocol was registered a priori in PROSPERO (ID# CDR42021240413). Of the 120 studies included (98 on SRIM, 18 on DOL, and 4 both), 37 (31%) studies were conducted in North America, followed by 26 (21.6%) in Europe, 25 (21%) in East Asia, and Pacific, 15 (12.5%) in Latin America and the Caribbean, 7 (6%) in the Middle East and North Africa, 5 (4%) in South Asia, 3 (2.5%) in Sub‐Saharan Africa, and 2 (1.7%) included multiple countries. A total of 79 studies were from high‐income countries, 30 from upper‐middle‐income, 10 from low‐middle‐income countries, and one study was conducted in a high‐income and an upper‐middle‐income country. Findings indicated that DOL increased the risk of SRIM. Protective factors identified for DOL and SRIM were hospital practices, such as timely breastfeeding (BF) initiation, avoiding in‐hospital commercial milk formula supplementation, and BF counselling/support. By contrast, maternal overweight/obesity, caesarean section, and poor maternal physical and mental health were risk factors for DOL and SRIM. SRIM was associated with primiparity, the mother's interpretation of the baby's fussiness or crying, and low maternal BF self‐efficacy. Biomedical factors including epidural anaesthesia and prolonged stage II labour were associated with DOL. Thus, to protect against SRIM and DOL it is key to prevent unnecessary caesarean sections, implement the Baby‐Friendly Ten Steps at maternity facilities, and provide BF counselling that includes baby behaviours. Socioeconomic and demographic factors indicative of lower economic status increased the risk of self‐reported insufficient milk (SRIM) and delayed onset of lactation (DOL). Timely breastfeeding (BF) initiation and avoidance of in‐hospital commercial milk formula (CMF) supplementation are likely to reduce the prevalence of SRIM and DOL. BF counselling designed to prevent SRIM and DOL needs to strengthen maternal BF self‐efficacy, maternal understanding of baby behaviours such as fussiness and maternal wellbeing. Research is needed to better understand how the risk of DOL and SRIM increases with primiparity, caesarean sections, maternal overweight/obesity, and poor overall maternal health. Intervention studies specifically designed to reduce the risk of SRIM and DOL are urgently needed in low‐ and middle‐income countries.

Abstract
Food systems are increasingly being understood as driving various health and ecological crises and their transformation is recognised as a key opportunity for planetary health. First-food systems represent an underexplored aspect of this transformation. Despite breastfeeding representing the optimal source of infant nutrition, use of commercial milk formula (CMF) is high and growing rapidly. In this review, we examine the impact of CMF use on planetary health, considering in particular its effects on climate change, water use and pollution and the consequences of these effects for human health. Milk is the main ingredient in the production of CMF, making the role of the dairy sector a key area of attention. We find that CMF use has twice the carbon footprint of breastfeeding, while 1 kg of CMF has a blue water footprint of 699 L; CMF has a significant and harmful environmental impact. Facilitation and protection of breastfeeding represents a key part of developing sustainable first-food systems and has huge potential benefits for maternal and child health.

Abstract
Background: Studies have shown that breastfeeding self-efficacy constitutes a determinant used to forecast breastfeeding behaviours. Objective: The aim of this study was to examine the factors associated to breastfeeding self-efficacy and identify its predictors among Greek women in their immediate postpartum period. Methods: A cross-sectional study was conducted at the General Hospital of Volos, Greece. A convenience sample of 120 postpartum women who gave birth at the hospital and met all the inclusion criteria were invited to participate; 100 responded. Questionnaires on socio-demographic, perinatal and breastfeeding-related characteristics, the Edinburgh Postnatal Depression Scale, and the Breastfeeding Self-Efficiency Scale were completed. Univariate and multivariate analyses were performed with the use of the linear regression model. Results: Women reported a rather good level of breastfeeding self-efficacy (mean = 3.65; SD = 0.85) in the early postpartum period. 52% of women carried out exclusive breastfeeding in the hospital. The prevalence of postnatal depression was 25%. The best-fit regression analysis revealed four predictors (timing of the mother’s decision to breastfeed, infant’s feeding pattern, previous breastfeeding experience, levels of postnatal depression) explaining 44.7% of the variance in breastfeeding self-efficacy. Conclusion: Acknowledging the determinants which affect breastfeeding self-efficacy of women in the immediate postpartum period is a necessary condition in designing targeted intervention services.

Abstract
BACKGROUND There is growing recognition that current food systems and policies are environmentally unsustainable. There is an identified need to integrate sustainability objectives into national food policy and dietary recommendations. RESEARCH AIMS To (1) describe exploratory estimates of greenhouse gas emission factors for all infant and young child milk formula products and (2) estimate national greenhouse gas emission association with commercial milk formulas sold in selected countries in the Asia Pacific region. METHOD We used a secondary data analysis descriptive design incorporating a Life Cycle Assessment (LCA) concepts and methodology to estimate kg CO2 eq. emissions per kg of milk formula, using greenhouse gas emission factors for milk powder, vegetable oils, and sugars identified from a literature review. Proportions of ingredients were calculated using FAO Codex Alimentarius guidance on milk formula products. Estimates were calculated for production and processing of individual ingredients from cradle to factory gate. Annual retail sales data for 2012-2017 was sourced from Euromonitor International for six purposively selected countries; Australia, South Korea, China, Malaysia, India, Philippines. RESULTS Annual emissions for milk formula products ranged from 3.95-4.04 kg CO2 eq. Milk formula sold in the six countries in 2012 contributed 2,893,030 tons CO2 eq. to global greenhouse gas emissions. Aggregate emissions were highest for products (e.g., toddler formula), which dominated sales growth. Projected 2017 emissions for milk formula retailed in China alone were 4,219,052 tons CO2 eq. CONCLUSIONS Policies, programs and investments to shift infant and young child diets towards less manufactured milk formula and more breastfeeding are "Triple Duty Actions" that help improve dietary quality and population health and improve the sustainability of the global food system.

Abstract
Although actions have been taken to improve breastfeeding in Mexico, trends over the last decade and their associated factors have not been analysed. We estimated trends in breastfeeding practices at the national, rural/urban, and regional level indigenous ethnicity and socio-economic level, and their associated factors using the National Demographic Dynamics Survey (2006, 2009, 2014 and 2018). We assessed breastfeeding indicators of women with children <24 months according to The World Health Organization recommendations. Logistic regressions models of pooled data were used to estimate trends and associations with biological and sociodemographic characteristics. Between 2006 and 2018, the prevalence of ever breastfed increased from 91.8% to 94.2% (p < 0.001), whereas early initiation of breastfeeding increased from 40.8% to 59.7% (p < 0.001), with similar increments by urban/rural level. Between 2009 and 2018, the prevalence of exclusive breastfeeding in children <6 months increased from 13.0% to 20.7% (p < 0.001). The largest increase was seen in Mexico City, in nonindigenous women and those with a high socio-economic status, whereas indigenous women and those from the South had the lowest or no improvements. Breastfeeding education during pregnancy [odds ratio (OR) 1.3; 95% confidence interval (CI) 1.1-1.5] was positively associated with exclusive breastfeeding, whereas being employed (OR 0.8; 95% CI 0.6-0.9) was negatively associated. Breastfeeding practices improved but are still far from recommendations. Implementing strategies like breastfeeding counselling and programmes and policies that promote and support breastfeeding for poor, indigenous, single and working mothers should be a priority for the government to ensure that all children have the best start in life.

[PMID: 33232335 PMCID: PMC7685454 DOI: 10.1371/journal.pone.0242457] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Accepted: 11/03/2020] [Indexed: 01/29/2023] Open
Abstract
The availability of breastfeeding support resources, including those provided by Baby-Friendly Hospitals, International Board Certified Lactation Consultants, breastfeeding counselors and educators, and volunteer-based mother-to-mother support organizations, such as La Leche League, are critically important for influencing breastfeeding initiation and continuation for the mother-child dyad. In addition, the emergence of community support options via information and communication technologies such as Skype and Facetime, social media (e.g., Facebook), and telelactation providers are providing mothers with a new range of support options that can help bridge geographic barriers to traditional community support. However, telelactation services that use information and communication technologies to connect breastfeeding mothers to remotely located breastfeeding experts require reliable, affordable, high-quality broadband connections to facilitate interaction between mothers and their support resources. The purpose of this paper is to explore the complex spatial landscape of virtual and face-to-face breastfeeding support options for mothers in the state of Ohio (U.S.), identifying barriers to support. Using a range of spatial and network analytics, the results suggest that a divide is emerging. While urban areas in Ohio benefit from both a density of face-to-face breastfeeding support resources and robust broadband options for engaging in telelactation, many rural areas of the state are lacking access to both. Policy implications and several potential strategies for mitigating these inequities are discussed.

Abstract
Zinc oxide nanoparticles (ZnO-NPs) have been extensively applied in our daily life. Humans are at high risk of being exposed to ZnO-NPs, which induce potentially adverse health effects. Although a growing number of studies have investigated the toxic effects of ZnO-NPs, the available data concerning ZnO-NP interactions with the blood-milk barrier (BMB) remain highly limited. Herein, we systematically investigated the damage to BMB integrity induced by ZnO-NPs and the mechanisms involved. ZnO-NPs that were intravenously injected into lactating dams accumulated in the mammary gland and entered into the breast milk, inducing disruption to BMB integrity and changes in the tight junction (TJ) and adherens junction (AJ) components. Furthermore, using an in vitro BMB model composed of EpH4-Ev cells, we verified that ZnO-NP-triggered ROS generation and the activation of MKK4 and JNK are the main mechanism of cell-cell junction damage. More interestingly, JNK activation played different roles in inducing changes in the TJ and AJ complex, and these effects did not need to activate the downstream c-Jun. These data provide more information for understanding ZnO-NP interactions with the BMB and raise concern for the daily use and the intravenous use of ZnO-NPs by lactating mothers.

First-food systems transformations and the ultra-processing of infant and young child diets: The determinants, dynamics and consequences of the global rise in commercial milk formula consumption. MATERNAL AND CHILD NUTRITION 2020; 17:e13097.

Abstract
The inappropriate marketing and aggressive promotion of breastmilk substitutes (BMS) undermines breastfeeding and harms child and maternal health in all country contexts. Although a global milk formula ‘sales boom’ is reportedly underway, few studies have investigated its dynamics and determinants. This study takes two steps. First, it describes trends and patterns in global formula sales volumes (apparent consumption), by country income and region. Data are reported for 77 countries, for the years 2005–19, and for the standard (0–6 months), follow‐up (7‐12 m), toddler (13‐36 m), and special (0‐6 m) categories. Second, it draws from the literature to understand how transformations underway in first‐food systems – those that provision foods for children aged 0–36 months – explain the global transition to higher formula diets. Total world formula sales grew by 115% between 2005 and 2019, from 3.5 to 7.4 kg/child, led by highly‐populated middle‐income countries. Growth was rapid in South East and East Asia, especially in China, which now accounts for one third of world sales. This transition is linked with factors that generate demand for BMS, including rising incomes, urbanisation, the changing nature of woman's work, social norms, media influences and medicalisation. It also reflects the globalization of the baby food industry and its supply chains, including the increasing intensity and sophistication of its marketing practices. Policy and regulatory frameworks designed to protect, promote and support breastfeeding are partially or completely inadequate in the majority of countries, hence supporting industry expansion over child nutrition. The results raise serious concern for global child and maternal health.

Abstract
Background: According to the Intergovernmental Panel on Climate Change, Greenhouse Gas emissions must decline by around 45% by 2030 and reach net zero in 2050. Biofuels, solar, and wind energy are obvious choices for reduction of the 75% of emissions from the energy sector (including transportation), but making reductions in the remaining 25%, the food sector, is more of a challenge. One way is to change our diets to increase low-carbon food alternatives. Objective: We chose to examine the impact of powdered baby formula products. The aim of this study is to compute a minimal estimate of green house gas (GHG) emissions for powdered baby formula products sold in North America comprising Canada, Mexico, and the United States. Results: We found that in 2016, the North America Greenhouse Gas emissions (in tons of CO2 eq.) attributable to sales of powdered formula for Canada was 70,256, for Mexico, 435,820, and for the United States, 655,956. The North American per capita emissions based on infants and toddlers from birth to 36 months of age in 2016 was, at a minimum, 59.06 kg of CO2 eq. Conclusion: The environmental and Greenhouse Gas impact of powdered baby formula, and related hazards arising from climate change, can be a relevant factor for health care providers in their advice to families on infant feeding. This study makes an innovative and potentially useful addition to the emerging evidence on this issue and should be considered when developing and funding infant and young child feeding policies and supportive programs.

Abstract
The health benefits of breastfeeding are well documented, and more than 80% of US women initiate breastfeeding; however, mothers in the United States face substantial challenges in meeting their personal breastfeeding goals, with approximately 60% weaning earlier than they had intended. In addition, there are significant racial/ethnic inequities in infant-feeding behaviors, and these inequities are a major public health concern. Enabling women to meet their breastfeeding goals is a public health priority. Infant feeding should be addressed as a modifiable health behavior, rather than a lifestyle choice.

Protective Effect of Breastfeeding on the Adverse Health Effects Induced by Air Pollution: Current Evidence and Possible Mechanisms. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16214181. [PMID: 31671856 PMCID: PMC6862650 DOI: 10.3390/ijerph16214181] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/06/2019] [Revised: 10/22/2019] [Accepted: 10/25/2019] [Indexed: 02/08/2023]
Abstract
Air pollution is a major social, economic, and health problem around the world. Children are particularly susceptible to the negative effects of air pollution due to their immaturity and excessive growth and development. The aims of this narrative review were to: (1) summarize evidence about the protective effects of breastfeeding on the adverse health effects of air pollution exposure, (2) define and describe the potential mechanisms underlying the protective effects of breastfeeding, and (3) examine the potential effects of air pollution on breastmilk composition and lactation. A literature search was conducted using electronic databases. Existing evidence suggests that breastfeeding has a protective effect on adverse outcomes of indoor and outdoor air pollution exposure in respiratory (infections, lung function, asthma symptoms) and immune (allergic, nervous and cardiovascular) systems, as well as under-five mortality in both developing and developed countries. However, some studies reported no protective effect of breastfeeding or even negative effects of breastfeeding for under-five mortality. Several possible mechanisms of the breastfeeding protective effect were proposed, including the beneficial influence of breastfeeding on immune, respiratory, and nervous systems, which are related to the immunomodulatory, anti-inflammatory, anti-oxidant, and neuroprotective properties of breastmilk. Breastmilk components responsible for its protective effect against air pollutants exposure may be long chain polyunsaturated fatty acids (LC PUFA), antioxidant vitamins, carotenoids, flavonoids, immunoglobins, and cytokines, some of which have concentrations that are diet-dependent. However, maternal exposure to air pollution is related to increased breastmilk concentrations of pollutants (e.g., Polycyclic aromatic hydrocarbons (PAHs) or heavy metals in particulate matter (PM)). Nonetheless, environmental studies have confirmed that breastmilk’s protective effects outweigh its potential health risk to the infant. Mothers should be encouraged and supported to breastfeed their infants due to its unique health benefits, as well as its limited ecological footprint, which is associated with decreased waste production and the emission of pollutants.
