Diets, stress, and disease in the Etruscan society: Isotope analysis and infantile skeletal palaeopathology from Pontecagnano (Campania, southern Italy, 730-580 BCE).

Susceptibility to morbidity and mortality is increased in early life, yet proactive measures, such as breastfeeding and weaning practices, can be taken through specific investments from parents and wider society. The extent to which such biosocialcultural investment was achieved within 1st millennium BCE Etruscan society, of whom little written sources are available, is unkown. This research investigates life histories in non-adults and adults from Pontecagnano (southern Italy, 730-580 BCE) in order to track cross-sectional and longitudinal breastfeeding and weaning patterns and to characterize the diet more broadly. Stable carbon and nitrogen isotope analysis of incrementally-sampled deciduous and permanent dentine (n = 15), bulk bone collagen (n = 38), and tooth enamel bioapatite (n = 21) reveal the diet was largely based on C3 staple crops with marginal contributions of animal protein. Millet was found to play a role for maternal diet and trajectories of breastfeeding and feeding for some infants and children at the site. The combination of multiple isotope systems and tissues demonstrates exclusive breastfeeding was pursued until 0.6 years, followed by progressive introduction of proteanocius supplementary foods during weaning that lasted between approximately 0.7 and 2.6 years. The combination of biochemical data with macroscopic skeletal lesions of infantile metabolic diseases and physiological stress markers showed high δ15Ndentine in the months prior to death consistent with the isotopic pattern of opposing covariance.

Children of the grave: Investigating non-adult feeding practices in medieval and early modern Estonia through stable isotope analysis.

Studying infant diet and feeding practices through stable isotope analysis provides direct insight into the life and health of vulnerable population groups in the past. Although the general diet in medieval and early modern Livonia has been reconstructed from written sources, little is known about childhood diet during this tumultuous period of Eastern European history. This study presents a comparative investigation of the staple non-adult diet in urban/rural communities during the 13th-17th centuries AD, with a special focus on feeding practices. We aim to reveal the impact of socio-economic circumstances on early childhood nutrition, which affects the physical development and overall survival of this susceptible population group. Bone collagen samples from 176 individuals between the fetal and the 7-15 age categories from four urban/rural South-Estonian cemeteries were cross-sectionally analyzed via EA-IRMS (Elemental Analysis with Isotope Ratio Mass Spectroscopy) for δ13C and δ15N. Results suggest that South-Estonian children had a staple terrestrial C3 diet integrated with animal proteins. Significant divergences were observed between urban and rural sites and slight variation occurred among rural subgroups, possibly resulting from a wider food choice available in towns, different consumption of C4 foods, and/or secular changes. This study provides the first data regarding infant feeding practices in medieval and early modern Livonia. These practices were similar among the different contexts, indicating comparable cultural traditions in child rearing. Breastfeeding was likely practiced for 1-2 years, with supplementary foods introduced around 1 year of age. The weaning process was probably concluded around the age of 3. The δ13C and δ15N values of older children are comparable to those of the adults from the same sites, indicating their diets became similar after weaning, when they started working and obtained a more mature social status.

Tracking breastfeeding and weaning practices in ancient populations by combining carbon, nitrogen and oxygen stable isotopes from multiple non-adult tissues.

This paper explores the potential of combining different isotope systems from different tissues to improve resolution when reconstructing breastfeeding and weaning practices (BWP) in archaeology. Additionally, we tested whether changes in diet can be detected in deciduous teeth. Rib collagen samples from 22 infants/children from the archaeological site of Bacuranao I (Mayabeque, Cuba) were processed for nitrogen (δ15N) and carbon (δ13Cco) stable isotopes and assessed using a Bayesian model (WARN). In addition, enamel of 48 teeth from 30 infants/children were analyzed for oxygen (δ18Oen) and carbon (δ13Cen) stable isotopes. Data revealed that the timing of weaning cannot be characterized precisely by analyzing either δ18O or δ15N. While a depletion in both δ15N and δ13Cco is only evident after one year, the WARN model suggested that the weaning process started at around 3 months and ended around 1.7 years. Most teeth were enriched in δ18Oen compared to deciduous incisors, suggesting a breastfeeding signal. However, a high variability in δ18O was found between similar teeth from the same individuals. Higher enrichment in δ18Oen, and variability, was observed in tissues formed during the first six months of life. A δ13C enrichment of 1.0‰ was observed among deciduous teeth and ribs. While most individuals enriched in δ15N showed enrichment in δ13C, the δ18O values were more variable. Our data suggests that stable isotopes of deciduous teeth, especially δ13Cen, can be used to detect changes in diet during the weaning process. It is also possible that the δ18O enrichment observed in M1 is influenced by the effects of cooking techniques on weaning foods. The combination of multiple isotope systems and tissues overcome some of the limitations posed by single tissue approaches.

Woman, Mother, Wet Nurse: Engine of Child Health Promotion in the Spanish Monarchy (1850-1910).

In Spain, the wet nurse increased the survival of children through care and breastfeeding of other women's children. They had a great development together with the Spanish monarchy between 1850 and 1910. The aim is to identify the role of wet nurses in the Spanish monarchy and the survival of the royal infants (s. XIX-XX). A scoping review is presented to study documents about the wet nurse in the Spanish monarchy. Applying the dialectical structural model of care (DSMC). Recognizing five thematic blocks that shape the historical-cultural model. Books, decrees and databases were analyzed: Scopus, Scielo, Dialnet, Cuiden, Medline/Pubmed, CINAHL, Science Direct and Google Scholar, from January to July 2020. The selection process was rigorous because it was difficult to choose. They had to overcome medical and moral exams. The selected rural northern wet nurses emigrated to Madrid. The contract was regulated by laws and paid. Wet nurses were hired by the monarchy due to health problems of the biological mother and a need for greater offspring. The wet nurse wore a typical costume, a symbol of wealth. The northern wet nurses hired by the monarchists have been the engine that has promoted the health of infants through the breastfeeding process.

Tolstoy's Life Lessons on Breastfeeding and Reducing Child Mortality.

The article is devoted to Leo Tolstoy's ideas about breastfeeding that he expressed eloquently in his novels, educational articles, and philosophical essays. Tolstoy's perspective on breastfeeding is discussed in his novella The Kreutzer Sonata and in his nonfiction of the late 1880s. His basic ideas had been shaped through his own experience and family life. Also important was his correspondence with the American physician, Alice Bunker Stockham, MD, an author of Tokology: A Book for Every Woman, and Tolstoy's editorial work on the medical brochure written by the head of Moscow Children's Hospital, E.A. Pokrovsky. Tolstoy's literary and historical accounts of breastfeeding promotion can help to understand the current day practices and ways in which cultural traditions are incorporated into infant care in contemporary Russia.

Growing up in Ancient Sardinia: Infant-toddler dietary changes revealed by the novel use of hydrogen isotopes (δ2H).

Detailed information about the lives and deaths of children in antiquity is often in short supply. Childhood dietary histories are, however, recorded and maintained in the teeth of both juveniles and adults. Primary tooth dentinal collagen does not turn over, preserving a sequential record of dietary changes. The use of nitrogen (δ15N) and carbon (δ13C) isotope values of incrementally sampled dentin are used in the study of breastfeeding practices but evidence for the addition of weaning foods, both in terms of mode and, particularly, duration, has remained analytically inaccessible to date. Here, we demonstrate how the novel use hydrogen isotope (δ2H) values of sequentially micro-sampled dentin collagen, measured from individuals excavated from a Punic cemetery, in Sardinia, Italy, can serve as a proxy for weaning food type and duration in ancient childhood diet. The weaning rate and age, based on the decline in δ15N and δ13C values of permanent first molars and the concomitant increase in δ2H, appears to be broadly similar among six individuals. Hydrogen isotopes vary systematically from a low value soon after birth, rising through early childhood. The early post-birth values can be explained by the influence of 2H-depleted lipids from mother's breastmilk and the later δ2H rise is consistent with, among other things, a substantial portion of boiled foodstuffs, such as the higher δ2H values observed in porridge. Overall δ2H in dentin shows great promise to elucidate infant and childhood feeding practices, and especially the introduction of supplementary foods during the weaning process.

Back to the Breast: An Historical Overview of the Perceived Connections Between Sudden Infant Death Syndrome and Breastfeeding.

In the late 19th century, physicians in the United States and Europe grew concerned about an increasingly visible subset of infant mortality: sudden infant death. Over the next 100 years, physicians worked variably to combat the problem, modifying and refining their conceptions of sudden infant mortality many times over the process. Physicians' overlapping revisions of sudden infant mortality ultimately helped to produce the categorization of Sudden Infant Death Syndrome (SIDS), and their ensuing, fluctuating efforts to resolve this problem shed light on social and medical perceptions of the roles that biology, the environment, and infant care practices played in sudden infant death. SIDS's official medical classification was a watershed; not only did the formal medical label establish its "authenticity" as a medical phenomenon, but the label also asserted the inexplicability of (at least some) sudden infant death episodes while simultaneously conveying that affected parents were deserving victims of a tragic loss. In the modern history of sudden infant death in the United States, breastfeeding, in particular, was understood variably as a possible cause for unnecessary infant mortality in the decades surrounding 1900; inconsequential to the occurrence of SIDS in the mid 1900s; and finally as an important and healthful way to reduce the risk for SIDS beginning in the late 1900s.

Historical Antecedents of Breastfeeding for African American Women: from the Pre-Colonial Period to the Mid-Twentieth Century.

INTRODUCTION: African American women have much lower breastfeeding rates than other racial and ethnic groups in the USA. While researchers are beginning to explore contemporary factors contributing to this inequality, much less research has been devoted to the historical conditions that have contributed to these disparities. AIM: The aim of this paper was to describe the social, economic, and political factors that have influenced African American breastfeeding behavior in the USA from the colonial era through the mid-twentieth century. METHODS: A thematic analysis was conducted across multiple databases and sources. A social history framework, which focuses on the experiences of ordinary people and events, was used to identify and integrate themes found within the reviewed literature. RESULTS: Three themes emerged: (1) Labor forces and other socio-cultural factors affected feeding practices and communal caregiving; (2) history of supplementation; and (3) influence of medicalization of birth and mobility on infant feeding in the twentieth century. These themes illustrate how African American women's ability to breastfeed has been significantly constrained throughout the U.S. HISTORY: Supplementation with non-human milk substitutes and communal caregiving helped African American women navigate infant rearing under adverse socioeconomic circumstances. CONCLUSIONS: Social, political, and economic factors have contributed significantly to African American women's ability to breastfeed throughout the U.S. HISTORY: Understanding the influences of historical antecedents on breastfeeding decisions over time may be key to finding effective interventions that might increase breastfeeding rates within this population.

Multi-proxy stable isotope analyses of dentine microsections reveal diachronic changes in life history adaptations, mobility, and tuberculosis-induced wasting in prehistoric Liguria (Finale Ligure, Italy, northwestern Mediterranean).

OBJECTIVE: To reconstruct breastfeeding and weaning practices, metabolic stress including tuberculosis-induced wasting, and residential mobility of children in Neolithic and Metal Ages to infer their local ecologies. MATERIALS: Seven permanent teeth from individuals dated to the Neolithic, Copper, Bronze, and Iron Ages buried in nearby caves in western Liguria, Italy. METHODS: Carbon, nitrogen, and sulfur stable isotope analyses on dentine microsections. Tooth maturation was used to calculate age at death. RESULTS: Two Neolithic children present longer pattern of weaning and appear to have been weaned using animal protein in contrast to the earlier weaning of Metal Ages children, which were probably weaned with vegetable resources. Sulfur isotopes suggest local origin of Neolithic and Cooper Age children, and non-local origins for Bronze and Iron Age children. Intense catabolism in the last two years is apparent in the adolescent with tuberculosis. CONCLUSIONS: Shortening in weaning patterns during the Metal Ages are likely driven by the intensification of agricultural practices and cultivation of new crops during Bronze and Iron Ages. Neolithic food choices and delayed weaning patterns may represent one of the strategies to maximize growth and immune potential in a local economy/ecology with high-infectious load. Tuberculosis was a chronic and long-lasting disease. SIGNIFICANCE: The first combined carbon, nitrogen, and sulfur analysis on prehistoric dentine microsections revealing changing human life history adaptations within the same region. LIMITATIONS: Small sample size. SUGGESTIONS FOR FURTHER RESEARCH: Increase the sulfur isotope dataset, use new EA-IRMS equipment, and provide data on amino acid to better define weaning food composition.

Prenatal Provider Support for Breastfeeding: Changes in Attitudes, Practices and Recommendations Over 22 Years.

BACKGROUND: Prenatal care providers play a central role in breastfeeding outcomes. A survey on obstetricians' support of breastfeeding was conducted in 1993 in Monroe County, NY. Since the landscape of prenatal care and breastfeeding support has changed significantly in the past 2 decades, we repeated and extended this survey in 2015. RESEARCH AIM: To determine changes in breastfeeding support by prenatal care providers over a 20 year period. METHODS: We sent a 46-item on-line or paper questionnaire to all categories of prenatal care providers identified by an online search. A breastfeeding support score was created based on the prior survey, with a maximum score of 3. One point was awarded for: (1) personally discussing breastfeeding; (2) generally suggesting breastfeeding; and (3) commonly receiving questions from patients. Data were analyzed using Chi-square. RESULTS: We had 164 participants (response rate 80%). More current participants, compared to 1993, reported discussing (97% vs. 86%, p < .001) and recommending (93% vs. 80%, p = .001) breastfeeding. Only 10% of 2015 participants gave infant formula samples, compared with 34% in 1993 (p < .0001). Improvement in the support score was seen, with 98% of current participants having high scores compared to 87% in 1993 (p < .001). Similar numbers reported receiving breastfeeding education, though more reported that the education was inadequate (54% vs. 19%, p < .0001). CONCLUSION: Breastfeeding support improved significantly over time, even though breastfeeding education has not improved in quality or quantity. Improving education of prenatal care providers may help future providers be more prepared to support breastfeeding.

Reconstructing breastfeeding and weaning practices in the Bronze Age Near East using stable nitrogen isotopes.

OBJECTIVES: Breastfeeding and childhood diet have significant impact on morbidity and mortality within a population, and in the ancient Near East, it is possible to compare bioarchaeological reconstruction of breastfeeding and weaning practices with the scant textual evidence. MATERIALS AND METHODS: Nitrogen stable isotopes (δ15 N) are analyzed here for dietary reconstruction in skeletal collections from five Bronze Age (ca. 2,800-1,200 BCE) sites in modern Lebanon and Syria. We employed Bayesian computational modeling on cross-sectional stable isotope data of collagen samples (n = 176) mainly from previous studies to test whether the bioarchaeological evidence aligns with the textual evidence of breastfeeding and weaning practices in the region, as well as compare the estimated weaning times to the global findings using the WARN (weaning age reconstruction with nitrogen isotope analysis) Bayesian model. RESULTS: Though the Near East sites in this study had different ecological settings and economic strategies, we found that weaning was introduced to the five sites at 0.5 ± 0.2 years of age and complete weaning occurred around 2.6 ± 0.3 years of age on using the WARN computational model. These weaning processes are within the time suggested by historical texts, though average estimated weaning age on the Mediterranean coast is later than inland sites. DISCUSSION: Compared globally, these Near Eastern populations initiated the weaning process earlier but completed weaning within the global average. Early initial weaning may have created short spacing between pregnancies and a high impact on demographic growth within these agricultural populations, with some variation in subsistence practices accounting for the inland/coastal discrepancies.

Societal perceptions and lived experience: Infant feeding practices in premodern Japan.

OBJECTIVES: A change in how children were treated and valued occurred in premodern Japan, as popularized ideas of an inheritance-based family system led to more careful and affectionate child-rearing practices by lower social-status groups. A number of books were written, advising that breastfeeding should last approximately 3 years. The objective of this study is to reconstruct and compare breastfeeding and weaning practices before and after the transition, to illuminate the impact of documented changes in child-rearing practices on subadults' lived experience. MATERIALS AND METHODS: Carbon and nitrogen stable isotopic data were obtained from 40 subadult skeletons excavated from the Sakai Kango Toshi 871 (SKT871) site (late 17th-19th century, Osaka, Japan). Isotopic results from SKT871 were compared with previously reported results from the Hitotsubashi site (AD 1657-1683, Tokyo, Japan). Hitotsubashi and SKT871 represent urban populations of lower status before and after the transition of societal perception of subadults. RESULTS: The most probable age at the end of weaning reconstructed in SKT871 was 1.9 years (1.4-2.7 years with a 95% credible interval) and was lower than that in Hitotsubashi (2.1-4.1 years with a 95% credible interval). DISCUSSION: The age at the end of weaning became younger after the transition of societal perception toward subadults, and this younger weaning age is inconsistent with written recommendations for the duration of weaning in premodern Japan. It is possible that an increased need for inheritors under the inheritance-based family system led to earlier weaning and shorter inter-birth intervals, but authorities recommended an ideal practice of a longer breastfeeding period.

[Alexandre Frias i Roig: childcare pediatrician, medical doctor and scientific disseminator. Tireless fighter in favor of breastfeeding and childhood]. / Alexandre Frias i Roig: puericultor, médico y divulgador. Luchador incansable en favor de la lactancia materna y de la infancia.

INTRODUCTION: Alexandre Frias was born in Reus, the city where he developed most of his professional activity. Medical doctor and childcare pediatrician, he worked tirelessly in order to improve children's health. He created the first Instituto de Puericultura Integral (Integral Institute of Childcare) in Spain in 1919, which remained in operation until his death. The Institute's activities began with a clinic for breastfeeding children, breastfeeding service and a biochemical analysis laboratory, later expanding with prenatal childcare services, a refectory for pregnant women and general women, a pediatric office with a vaccination service and, as a complement, a home health care service and medical obstetrics. Convinced that breastfeeding and hygiene were fundamental for the prevention of diseases, he carried out an enormous educational work among mothers, doctors, governors and society in general. Forerunner of numerous initiatives for curative and preventive purposes, he established health education for mothers and professionals, school colonies, medical-school inspection, home delivery of scales for weight control and incubators for premature children and even a hygienic dress model for newborns. He made numerous publications as books form, such as the one entitled "Lo que deben saber las madres", booklets and newspapers articles. He founded and directed the scientific journal Puericultura (child care), published in Reus and distributed throughout the country until 1936. Its incessant activity in favor of the fight against infant mortality drastically reduced infant/children mortality in Reus and influenced the health and demographic improvement of all of Spain.

INTRODUCCIÓN: Alexandre Frias nació en Reus, ciudad donde desarrolló la mayor parte de su actividad profesional. Médico y puericultor, trabajó incansablemente con el fin de mejorar la salud infantil. Creó el primer Instituto de Puericultura integral de España en 1919, que se mantuvo en funcionamiento hasta su muerte. Las actividades del instituto se iniciaron con un consultorio para niños lactantes, servicio de lactario y un laboratorio de análisis, y se ampliaron posteriormente con servicios de puericultura prenatal, refectorio para embarazadas y mujeres, un consultorio de pediatría con servicio de vacunación y, como complemento, un servicio de asistencia domiciliaria de comadrona y un médico tocólogo. Convencido de que la lactancia materna y la higiene eran fundamentales para la prevención de enfermedades, realizó una ingente labor educativa entre madres, médicos, gobernantes y sociedad en general. Precursor de numerosas iniciativas con fines curativos y preventivos, instauró la educación sanitaria para madres y profesionales, las colonias escolares, la inspección médica-escolar, el servicio a domicilio de básculas para control de peso e incubadoras para niños prematuros e incluso un modelo de vestido higiénico para recién nacidos. Realizó numerosas publicaciones en forma de libros, como el titulado "Lo que deben saber las madres", opúsculos y artículos de prensa. Fundó y dirigió la revista Puericultura, editada en Reus y distribuida a todo el país, que se publicó hasta 1936. Su incesante actividad en pro de la lucha contra la mortalidad infantil redujo drásticamente las muertes en Reus e influyó en la mejora sanitaria y demográfica de toda España.

Is breastfeeding 'normal'? Using the right language for breastfeeding.

BACKGROUND: Accurate terms aid clarity in thinking and prevent confusion. In the infant feeding field 'normal' can be ambiguous as biologically normal may not equate with culturally normal in a given time or place. Similarly, the use of the term 'intervention' is appropriate if a recommended practice is not perceived as 'normal' to that culture. OBJECTIVE: This article explores the meaning of 'normal' in the context of infant feeding, since mothers may not perceive breastfeeding as 'normal' when this differs from the experience in communities in which it is considered unusual. METHODS: Historical and recent sources were used to explore the effect of culture and established practice on perceptions of what is 'normal'. DISCUSSION: Iceland and several regions of Europe are used as examples of long-term abandonment of breastfeeding during the late Medieval and Early Modern periods and the 19th century. Ireland, the United Kingdom and the United States are discussed in relation to fluctuations and declines in breastfeeding prevalence in the 20th and 21st centuries. The rôle of science and the rise of mother-support groups for breastfeeding, interventions to promote breastfeeding, and the possibility of cultural change, are also discussed. IMPLICATIONS FOR PRACTICE: Culture influences the perception of what is 'normal' and where a culture has abandoned breastfeeding, or where it is in decline, women are unlikely to view it as the normal way to feed an infant. A more appropriate use of language is recommended, describing breastfeeding as 'biologically normal' or 'physiologically normal', as it is not always, and has not always been, culturally normal. In this context initiatives to improve breastfeeding rates can correctly be termed 'interventions'.

'If We Are to Believe the Psychologists ': Medicine, Psychoanalysis and Breastfeeding in Britain, 1900-55.

In 1942, the British Minister of Health commissioned a report from the newly established Advisory Committee on Mothers and Young Children into 'What can be done to intensify the effort to secure more breast feeding of infants?'. To make their case, the members of the sub-committee put in charge of the report sought expert testimony on the benefits of breastfeeding. They consulted medical officers of health, maternity and child-welfare officers, health visitors, midwives, obstetricians, paediatricians and a physician in private practice. They also consulted five 'psychologists' (a contemporary umbrella term for psychologists, psychoanalysts and psychiatrists). It is not surprising that the committee turned to medical professionals, as infant feeding had long been an area of their expertise. However, seeking the views of 'psychologists' when establishing the benefits of breastfeeding marked a more innovative development, one which suggested that a shift in conceptualising the significance of breastfeeding was gathering pace. In the interwar period, psychoanalysts and psychoanalytically oriented psychiatrists showed growing interest in early infancy. It led to an extensive psychoanalytic engagement with contemporary feeding advice disseminated by the medical profession. This article will explore the divergences and intersections of medical and psychoanalytic theories on breastfeeding in the first half of the twentieth century, concluding with a consideration of how medical ideas on breastfeeding had absorbed some of the contentions of 'psy'-approaches to infant feeding by the post-war period.

[Biopolitics for breastfeeding: an analysis of the global and local movements and their links to social development discourses]. / Biopolíticas do aleitamento materno: uma análise dos movimentos global e local e suas articulações com os discursos do desenvolvimento social.

This study aimed to analyze the links between the production of biopolitics for breastfeeding and social development discourses after the post-war period, with a view towards problematizing the nature/culture dichotomy by which breastfeeding is often operationalized. The study adopts an anthropological perspective to compare biopolitics for breastfeeding with the changes in developmentalist discourses. The analysis of global movements by these biopolitics helped explain how a network of distinct entities (e.g., government agencies, multilateral bodies, international development agencies, and nongovernmental organizations) have shaped breastfeeding over time in keeping with the prevailing developmentalist discourses and practices. Initially, the developmentalist discourse focused on industrialization and modernization, and breastfeeding was not the focus of public policies. In the 1970s and 1980s, when the developmentalist discourse shifted the focus to child malnutrition and infant mortality, the first global biopolitics for breastfeeding were launched, and breastfeeding practice began to be operationalized as a means to fight these health problems. Meanwhile, the contemporary social development discourse also evokes a process of individual development. Simultaneously, biopolitics for breastfeeding rely on various technologies for this purpose. The conclusion is that developmentalist discourses act as a sociocultural reference by which breastfeeding is operationalized, and thus that breastfeeding is not only a natural process, but also a political, economic, and social one.

Este artigo tem como objetivo analisar as articulações entre a produção das biopolíticas de amamentação e os discursos produzidos sobre desenvolvimento social após o período pós-guerra com vistas à problematização da dicotomia natureza/cultura mediante a qual a amamentação é frequentemente operada. Numa perspectiva antropológica, examinaram-se as biopolíticas de amamentação comparativamente às transformações nos discursos desenvolvimentistas. O exame dos movimentos globais realizadas por essas biopolíticas permitiu compreender como uma rede de entidades variadas (como órgãos de governo, organismos multilaterais, agências internacionais de desenvolvimento e organizações não-governamentais) vem configurando ao longo do tempo a amamentação em conformidade com os discursos e práticas desenvolvimentistas em vigor. Inicialmente, o discurso desenvolvimentista girava em torno da industrialização e modernização, e a amamentação não era foco de atenção das políticas públicas. Nas décadas de 1970 e 1980, quando o discurso desenvolvimentista passou a focar a desnutrição e a mortalidade infantil, têm início as primeiras biopolíticas globais de amamentação e a prática da amamentação passa a ser operada como um meio de combater tais males. Já o discurso de desenvolvimento social em jogo na contemporaneidade evoca também um processo de desenvolvimento individual. Simultaneamente, as biopolíticas de amamentação recorrem a tecnologias variadas com este propósito. Conclui-se que os discursos desenvolvimentistas atuam como uma referência sociocultural com base na qual a amamentação é operada, o que permite dizer que a amamentação é uma prática tão natural quanto política, econômica e social.

El objetivo de este artículo ha sido analizar los vínculos entre la generación de biopolíticas en lactancia materna y los discursos existentes sobre desarrollo social, tras el período de posguerra, relacionados con la problematización de la dicotomía naturaleza/cultura, a través de la cual transita frecuentemente lactancia materna. Desde una perspectiva antropológica, se examinaron comparativamente biopolíticas en lactancia materna con transformaciones surgidas en los discursos desarrollistas. El examen de los movimientos globales, realizados por esas biopolíticas, permitió comprender cómo una red de entidades variadas (como órganos de gobierno, organismos multilaterales, agencias internacionales de desarrollo y organizaciones no gubernamentales) han considerado a lo largo del tiempo la lactancia materna, según los discursos y prácticas desarrollistas en vigor. Inicialmente, el discurso desarrollista giraba en torno a la industrialización y modernización, y la lactancia materna no era el centro de atención de las políticas públicas. En las décadas de los 1970 y 1980, cuando el discurso desarrollista pasó a centrarse en la desnutrición y la mortalidad infantil, comenzaron las primeras biopolíticas globales en lactancia materna y la práctica de la lactancia pasó a ser tratada como un medio de combatir tales males. Ya el discurso de desarrollo social en boga en la contemporaneidad evoca también un proceso de desarrollo individual. Simultáneamente, las biopolíticas en lactancia materna exploran tecnologías variadas con este propósito. Se concluye que los discursos desarrollistas actúan como una referencia sociocultural, basándose en cómo es operada la lactancia materna, lo que permite considerarla una práctica tan natural, como política, económica y social.

Black Nurse, White Milk: Breastfeeding, Slavery, and Abolition in 19th-Century Brazil.

Brazil imported more enslaved Africans than any other slave-owning society in the Americas, and it was the last country in the western hemisphere to abolish the institution. Whereas many enslaved persons toiled on plantations and in mines, urban slavery was also prominent, with enslaved men carrying coffee through the streets and enslaved women washing clothes. One gendered aspect of urban slavery in 19th-century Brazil included slave owners renting out enslaved women as wet nurses to breastfeed the children of elite families. This article reviews medical dissertations, debates, and journal articles, as well as advertisements for wet nurses, showing that physicians believed that enslaved women's milk was both nutritionally and morally inferior to white women's milk. In the latter half of the 19th century, physicians viewed abolition as the only answer to what they deemed the increasingly "dangerous" practice of enslaved wet nursing, which they believed was the root cause of high infant mortality rates across races and classes. Readers should consider the ethical dilemmas of the practice of enslaved wet nursing, which often resulted in the violent separation of mother and child.

"They Lacked the Right Food": A Brief History of Breastfeeding and the Quest for Social Justice.

In the late 19th-century United States and Europe, infants died at high rates from diarrhea. Physicians and social justice advocates responded to the public health crisis with attempts to clean up the water and cows' milk supplies, as well as social welfare legislation and assorted educational efforts to help mothers better care for their children. Most visible among the educational efforts were breastfeeding campaigns. A century later in developing countries, physicians and activists were confronted with a similar problem-infants dying from diarrhea due to the unethical advertising and marketing practices of formula companies. I argue in this article that crusades for social justice at the most basic level-to ensure that children will live to adulthood-have long been connected with efforts to safeguard mothers' ability to adequately breastfeed their children.
