Factors associated with early initiation of breastfeeding

Introduction: Early initiation of breastfeeding (EIBF) is still little stimulated in several hospitals in Brazil. Objective: To estimate the prevalence and factors associated with Early initiation of breastfeeding (EIBF). Methods: Cross-sectional, quantitative study with retrospective secondary data collection in hospital records of 250 full-term newborns, regardless of the type of delivery, with no history of maternal gestational risk, seen in the last six months. Data collection period in a public maternity hospital in Greater São Paulo. Data collection was performed between November 2018 and January 2019, with approval from the hospital and the FMABC Research Ethics Committee under register n. 2,924,393. Results: The prevalence of EIBF was 66%. BFH is associated with anesthesia at childbirth (p<0,001), APGAR less than or equal to 8 in the 1st and 5th minutes (p<0,001), and with c-section (p<0,001), which represented 29.2% of deliveries in the sample. Respiratory distress (38.82%), hypotonia (24.70%), followed by unfavorable maternal conditions (18.82%), were shown to be impeding factors for EIBF, although 90% of newborns received Apgar 9 /10 in the 5th minute. Conclusion: The prevalence of early breastfeeding is lower than recommended, but compatible with the most recent national frequency proportions.

Objective: to investigate breastfeeding with a focus on the exclusivity of this practice in the first semester of a child's life in a municipality in the north of Minas Gerais. Methods: this is a descriptive, qualitative study carried out with 13 mothers aged between 24 and 39 years old. Data were collected between August and September 2023 from a semi-structured interview and analyzed using Thematic Analysis. Results: women indicated that they faced difficulties in practicing exclusive breastfeeding, especially in the first days of the child's life, due to engorgement, mastitis, breast fissures, and social and personal pressure of weak milk. The benefits of exclusive breastfeeding were identified as immunological protection, strengthening bonds, preventing diseases and malnutrition in children, as well as accelerating uterine involution, and preventing cancer in women. Support from family, partner, and healthcare team was identified as factors that facilitate breastfeeding, but they indicated that they received little guidance from professionals about breastfeeding. Conclusion: the importance of the health team acting with a zealous eye towards the public is highlighted, intensifying guidance on exclusive breastfeeding in order to reduce doubts and difficulties in increasing the duration and exclusivity of breastfeeding.

Comparação da introdução das consistências na introdução da alimentação complementar entre recém-nascidos prematuros e a termo - Coorte de 0 a 12 meses / Comparison of the introduction of consistencies in complementary feeding introduction between preterm and full-term newborns - Cohort from 0 to 12 months

RESUMO Objetivo Comparar a introdução das consistências no período da alimentação complementar de recém-nascidos prematuros e recém-nascidos a termo até os 12 meses de vida, bem como avaliar a presença de disfunção motora oral e a sua relação com dificuldade na introdução das consistências alimentares nestes grupos. Método Trata-se de um estudo do tipo observacional, analítico, coorte, com coleta de dados ambispectiva, realizado na Secretaria Municipal de Saúde de Mafra - SC. A amostra do estudo foi constituída de 87 recém-nascidos, sendo 41 a termo e 46 prematuros. Na coleta de dados, foram realizadas entrevistas com as mães/responsáveis. A avaliação antropométrica foi realizada por nutricionista por meio de mensuração do peso corporal, comprimento e perímetro cefálico, seguida de avaliação das habilidades motoras orais e funcionais por meio do PAD-PED adaptado, avaliação da mamada, avaliação do desenvolvimento neuropsicomotor, avaliação da presença de depressão materna e risco psíquico da criança, até os 12 meses de vida de idade corrigida. Resultados A disfunção motora oral foi observada em 15 recém-nascidos, em ambos os grupos, na consistência líquida na primeira avaliação, persistiu em dois casos nos recém-nascidos a termo e em três casos nos recém-nascidos pré-termo, na última avaliação para a consistência sólida. Conclusão Não foi observada diferença na introdução das consistências alimentares entre os grupos. O aleitamento materno foi mais frequente nos a termo na primeira avaliação e semelhante nas demais avaliações. Com relação aos preditivos para disfunção motora oral, a mamadeira aumentou a chance em cerca de 7 vezes e procedimentos orais invasivos cerca de 6 vezes.

ABSTRACT Purpose To compare the introduction of consistencies during the period of complementary feeding of preterm and full-term newborns up to 12 months of life, as well as to evaluate the presence of oral motor dysfunction and its relation to difficulty in introducing food consistencies in these groups. Methods This is an observational, analytical, cohort study, with ambispective data collection, carried out at the Municipal Department of Health of Mafra, state of Santa Catarina, Brazil. The study sample consisted of 87 newborns, 41 full-term and 46 preterm. While data was collected, interviews were held with the mothers/guardians. The anthropometric assessment was carried out by a nutritionist by measuring body weight, length, and head circumference, followed by assessment of oral and functional motor skills by the adapted Clinical Evaluation Protocol of Pediatric Dysphagia (PAD-PED), assessment of breastfeeding and neuropsychomotor development, and assessment of the presence of maternal depression and psychological risk of children with up to 12 months of corrected age. Results We verified oral motor dysfunction in 15 newborns, in both groups, in the liquid consistency in the first assessment, persisting in two cases in the full-term newborns and in three cases in the preterm infants, in the last assessment for the solid consistency. Conclusion We observed no difference in the introduction of food consistencies between groups. Breastfeeding was more frequent in newborns in the first assessment and similar in other assessments. Regarding the predictors for oral motor dysfunction, bottle feeding increased the odds by about seven times and invasive oral procedures by about six times.

Exclusive breastfeeding intention among pregnant women and associated variables: a cross-sectional study in a Brazilian community / Intenção de amamentar entre gestantes e variáveis associadas: estudo transversal em uma comunidade brasileira

ABSTRACT Objective: To investigate exclusive breastfeeding (EBF) intention and associated variables among women in the third trimester of pregnancy. Methods: The data were collected with a questionnaire for the pregnant women (n=653), from December/2018 to November/2019. They answered the Infant Feeding Intentions (IFI) scale, translated and adapted to Brazilian Portuguese, and a questionnaire on sociodemographic, biological, family, pregnancy, breastfeeding, health care, and habits variables. Descriptive statistics and multiple logistic regression analyses were performed with a 5% significance level, following a multilevel hierarchical model that estimated the association between the dependent and independent variables. The outcome EBF intention measured by the IFI score was dichotomized by the median (<16 or =16). Results: Mean±standard deviation score for the IFI scale was 14.4±2.6 (score 0: very strong intention to not breastfeed at all; score 16: very strong EBF intention up to six months). The results from the regression analysis showed that pregnant women who had no intention to bottle feed (OR=4.33; 95%CI 2.79-6.72) or did not know (OR=1.85; 95%CI 1.21-2.82), those who planned the pregnancy (OR=1.52; 95%CI 1.09-2.12), those who believed they would have help to care for the baby (OR=3.60; 95%CI 1.51-8.56) or did not know (OR=3.97; 95%CI 1.26-12.51), and those who reported knowing the World Health Organization recommendations on breastfeeding (OR=1.73; 95%CI 1.13-2.64) were more likely to show a very strong EBF intention. Conclusions: Pregnant women in the third trimester of pregnancy presented a strong EBF intention. The higher EBF intention score was significantly associated with the structural, setting, and individual determinants.

RESUMO Objetivo: Investigar a intenção materna de amamentar exclusivamente (IMA) e variáveis associadas entre as mulheres no terceiro trimestre de gravidez. Métodos: A coleta de dados foi realizada por meio de entrevista e questionário semiestruturado e autoadministrado, entre dezembro/2018 e novembro/2019. As gestantes (n=653) responderam à escala Infant Feeding Intentions (IFI) testada, traduzida e adaptada para o português do Brasil e ao questionário contendo perguntas sobre variáveis sociodemográficas, biológicas e familiares, bem como relacionadas à gestação, ao aleitamento materno, à assistência à saúde e a hábitos. Foram realizadas análises estatísticas descritivas e de regressão logística múltipla hierarquizada, com nível de significância de 5%, para estimar a associação entre as variáveis independentes e o desfecho. A IMA, medida pela escala IFI, foi dicotomizada pela mediana (<16 ou =16). Resultados: A pontuação média±desvio padrão para a escala IFI foi de 14,4±2,6. Os resultados da análise de regressão mostraram que as gestantes que não tinham intenção de oferecer mamadeira (OR=4,33; IC95% 2,79-6,72) ou não sabiam (OR=1,85; IC95% 1,21-2,82), que planejaram a gestação (OR=1,52; IC95% 1,09-2,12), aquelas que acreditavam que teriam ajuda nos cuidados com o bebê (OR=3,60; IC95% 1,51-8,56) ou que não sabiam (OR=3,97; IC95% 1,26-12,51), bem como aquelas que relataram conhecer as recomendações da Organização Mundial de Saúde sobre amamentação (OR=1,73; IC95% 1.13-2.64) tinham mais chances de mostrar uma IMA muito forte. Conclusões: As gestantes no terceiro trimestre de gestação apresentaram forte IMA. A maior IMA esteve significativamente associada aos determinantes estruturais, contextuais e individuais.

Improving breastfeeding among adolescent mothers: a prospective cohort

ABSTRACT BACKGROUND: Exclusive breastfeeding is recommended for the first six months, and mother's age impact early weaning. Educational support and relevant information can increase breastfeeding rates. OBJECTIVE: To determine whether antenatal education enhances the maintenance, intention, and confidence in breastfeeding among adolescents. DESIGN AND SETTING: A prospective cohort study involving primiparous adolescents who gave birth at the Woman's Hospital (CAISM), Universidade Estadual de Campinas, Brazil. METHODS: Adolescent mothers were categorized into two groups based on the location of prenatal care: those at the Woman's Hospital (WH) who received antenatal education, and at the Primary Care (PC) who did not receive antenatal education. All adolescents received breastfeeding orientation during their postpartum hospital stay. The groups were compared using the Student's t-test, Mann-Whitney U test, and chi-squared test. Log-binomial models were used to compare the groups at different time intervals. RESULTS: The study included 132 adolescents: 59 in the WH group and 73 in the PC group. Six months postpartum, adolescents in the WH group demonstrated higher engagement in breastfeeding (P < 0.005) and exclusive breastfeeding (P = 0.04) than PC group. PC group showed greater lack of confidence in breastfeeding (P = 0.02) and felt less prepared (P = 0.01). Notably, all WH adolescents reported a stronger desire to breastfeed after antenatal education. CONCLUSION: Antenatal education significantly improves the maintenance, intention, and confidence of breastfeeding among adolescents. This education approach can be implemented across all healthcare levels and should be made accessible to all women throughout the pregnancy and postpartum period.

Outcomes and factors associated with tolerance in infants with non-IgE-mediated cow's milk allergy with gastrointestinal manifestations

Abstract Objectives To evaluate outcomes of oral food challenge (OFC) test to assess tolerance in infants with non-IgE-mediated cow's milk allergy (CMA) with gastrointestinal manifestations and explore clinical data predictive of these outcomes. Methods Single-center retrospective study including infants (age < 12 months) who were referred for CMA between 2000 and 2018 and underwent OFC on follow-up. A univariate logistic regression test was performed to evaluate variables associated with the outcomes of the follow-up OFC test. Results Eighty-two patients were included, 50% were male. Eighteen patients had a positive OFC test (22%). Most patients had presented with hematochezia (77%). The median age of symptom onset was 30 days. Two-thirds of the patients were on appropriate infant formula (extensively hydrolyzed or amino acid-based formula), exclusively or in association with breastfeeding. The median time on an elimination diet before the OFC test was 8 months (Q1 6 - Q3 11 months). All cases with positive follow-up OFC tests (n= 18) had been exposed to cow's milk-based formula before the first clinical manifestation of CMA. Five out of eight cases with Food Protein-Induced Enterocolitis Syndrome (FPIES) had positive OFC tests. Exposure to cow's milk-based formula before diagnosis, a history of other food allergies, hematochezia and diarrhea were predictors of a positive OFC test. Conclusions In infants with non-IgE-mediated CMPA with gastrointestinal manifestations, the use of cow's milk-based formula, a history of other food allergies, and hematochezia and diarrhea upon initial presentation were associated factors for the later achievement of tolerance.

Effects of oxytocin induction on early postpartum hemorrhage, perineal integrity, and breastfeeding: a case-control study

SUMMARY OBJECTIVE: The aim of this study was to evaluate the postpartum hemorrhage, perineal integrity, and breastfeeding results of mothers who underwent oxytocin induction in the first stage of labor in the early postpartum period. METHODS: This single-center observational case-control study was conducted in the obstetric unit of a public hospital in Istanbul. The study sampling included 44 pregnant women who received oxytocin induction (case group) and 44 pregnant women who did not receive oxytocin (control group). The Personal Information Form, LATCH Breastfeeding Assessment Tool, Breastfeeding Self-Efficacy Scale, Redness, Edema, Ecchymosis, Discharge, and Approximation Scale, and Postpartum Hemorrhage Collection Bag were used in data collection, and pad follow-up was carried out. RESULTS: The amount of hemorrhage in the first 24 h of the postpartum period and the mean Redness, Edema, Ecchymosis, Discharge, and Approximation Scale score were significantly higher in the case group. While 47.7% of the oxytocin-induced women had 1st or 2nd, and 11.4% had 3rd or 4th degrees of lacerations, 20.5% of the control group had 1st or 2nd, and 2.3% had 3rd or 4th degrees of lacerations. There was no significant difference between the mean scores of the Breastfeeding Self-Efficacy Scale and LATCH Breastfeeding Assessment Tool in both groups. CONCLUSION: According to the study findings, it was determined that oxytocin induction administered in the first stage of labor increased hemorrhage and perineal trauma in the early postpartum period but did not affect the results of breastfeeding. Clinical Trial Registration Number: NCT04441125.

Determinants of continued breastfeeding in children aged 12-23 months in three regions of Haiti / Determinantes de la continuación de la lactancia materna en la población infantil de entre 12 y 23 meses en tres regiones de Haití / Determinantes do aleitamento materno continuado em crianças de 12 a 23 meses de idade em três regiões do Haiti

ABSTRACT Objectives To identify the prevalence and determinants of continued breastfeeding in Haitian children aged 12-23 months. Methods Three cross-sectional surveys were conducted yearly during the summers of 2017 to 2019 as part of a 4-year (2016-2020) multisectoral maternal and infant health initiative in the regions of Les Cayes, Jérémie, and Anse d'Hainault in Haiti. A total of 455 children 12-23 months of age and their mothers participated in the study. A child was considered to be continuing breastfeeding if the mother reported giving breast milk in the 24-hour dietary recall. Unadjusted and adjusted prevalence ratios were estimated, and associations were assessed between continued breastfeeding and explanatory factors related to sociodemographic characteristics, household food security, maternal nutrition, and breastfeeding knowledge and practices. Results The prevalence of continued breastfeeding was 45.8%. Continued breastfeeding was significantly more prevalent among younger children, children who did not have a younger sibling, children whose mother was not pregnant, those living in the Jérémie region, children who had been exclusively breastfed for less than 1 month, and children whose mother knew the World Health Organization's recommendation for continued breastfeeding up to 2 years or beyond. Conclusions The study results highlight the need for geographically equitable access to tailored and adequate health services and education that support breastfeeding in a way that is compatible with the local context.

RESUMEN Objetivos. Determinar la prevalencia y los determinantes asociados a la continuación de la lactancia materna en la población infantil haitiana de entre 12 y 23 meses. Métodos. Durante los veranos del 2017 al 2019 se llevaron a cabo tres encuestas transversales anuales como parte de una iniciativa multisectorial de salud materna e infantil de 4 años (2016 a 2020) en las regiones de Les Cayes, Jérémie y Anse d'Hainault de Haití. En el estudio participaron 455 menores de edades comprendidas entre 12 y 23 meses y sus madres. Se consideró que un menor continuaba con la lactancia materna si, en la evaluación de la alimentación basada en el recuerdo de 24 horas, la madre declaraba la toma de leche materna. Se calcularon los cocientes de prevalencia ajustados y sin ajustar y se evaluó la asociación entre la continuación de la lactancia materna y posibles factores explicativos relacionados con las características sociodemográficas, la seguridad alimentaria de la familia, la nutrición materna y los conocimientos y prácticas en materia lactancia materna. Resultados. La prevalencia de la continuación de la lactancia materna fue del 45,8%. Esta prevalencia fue significativamente mayor cuando se trataba de lactantes de menor edad, cuando no había hermanos menores, cuando la madre no estaba embarazada, en los residentes en la región de Jérémie, cuando había habido una alimentación exclusiva con leche materna durante menos de un mes y cuando la madre conocía la recomendación de la Organización Mundial de la Salud de continuar con la lactancia materna hasta los dos años o más. Conclusiones. Los resultados del estudio ponen de relieve la necesidad de disponer de un acceso geográfico equitativo a unos servicios de salud y una educación que respalden la lactancia materna de una manera compatible con el contexto local.

RESUMO Objetivos Identificar a prevalência e os determinantes do aleitamento materno continuado em crianças haitianas de 12 a 23 meses de idade. Métodos Três pesquisas transversais foram realizadas anualmente nos verões de 2017 a 2019 como parte de uma iniciativa multissetorial de saúde materno-infantil de quatro anos (2016-2020) nas regiões de Les Cayes, Jérémie e Anse d'Hainault no Haiti. Um total de 455 crianças de 12 a 23 meses de idade e suas mães participaram do estudo. Considerou-se que a criança continuava sendo amamentada se a mãe relatasse ter dado leite materno no recordatório alimentar de 24 horas. Foram estimadas as taxas de prevalência não ajustadas e ajustadas e foram avaliadas as associações entre o aleitamento materno continuado e os fatores explicativos relacionados às características sociodemográficas, à segurança alimentar da família, à nutrição materna e aos conhecimentos e práticas de aleitamento materno. Resultados A prevalência de aleitamento materno continuado foi de 45,8%. O aleitamento materno continuado foi significativamente mais prevalente entre crianças mais novas, crianças que não tinham irmão mais novo, crianças cuja mãe não estava grávida, residentes da região de Jérémie, crianças que haviam sido exclusivamente amamentadas por menos de um mês e crianças cuja mãe conhecia a recomendação da Organização Mundial da Saúde de manter o aleitamento materno por 2 anos ou mais. Conclusões Os resultados do estudo destacam a necessidade de acesso geograficamente equitativo a educação e serviços de saúde adaptados e adequados para apoiar o aleitamento materno de forma compatível com o contexto local.

Aspectos Morfológicos de la Mama. Una Revisión de la Literatura / Morphological Aspects of the Breast. A Literature Review

La glándula mamaria tiene su origen embriológico, posteriormente se diferencia histológica y anatómicamente; a lo largo del tiempo se han ido descubriendo nuevos hallazgos, además de nueva terminología. El objetivo de este trabajo consistió en describir la actualización en los aspectos morfológicos de la glándula mamaria. Se realizó una búsqueda de artículos en diferentes fuentes primarias y secundarias de la literatura científica como: Pubmed, Embase, WOS, Scopus, Scielo obteniendo 623 publicaciones, seleccionado 53 para su revisión y 17 incluidos. La mama se ha ido actualizando en los aspectos morfológicos; Los conductos se ubican cercanos a la areola y al pezón donde desembocan directamente, las ramificaciones de los conductos se ubican cercanos a la areola; los pezones tienen entre 15 y 20 lóbulos, de los cuales sólo 5-9 son verdaderos orificios del conducto mamario, no existen senos lactíferos por lo que la leche desemboca directamente en el pezón, en cuanto a la inervación de la mama son inervados por las ramas cutáneas anterior y lateral de los nervios intercostales. La evidencia existente demuestra la necesidad de realizar estudios permanentes en el ámbito de la morfología, como fue descrito en este artículo de revisión sobre la mama. En diferentes aspectos, tales como términos, funciones y estructuras. Está información es importante para, la formación de pregrado, post grado, y su utilización en la clínica, identificación de patologías, clínicas de lactancia, entre otros.

SUMMARY: The mammary gland has its embryological origin, later it differentiates histologically and anatomically; over time new findings have been discovered, as well as new terminology. The aim of this work was to describe the update on the morphological aspects of the mammary gland. A search for articles was carried out in different primary and secondary sources of scientific literature such as: Pubmed, Embase, WOS, Scopus, Scielo, obtaining 623 publications, 53 selected for review and 17 included. The breast has been updated in morphological aspects; the ducts are located close to the areola and the nipple where they open directly, the branches of the ducts are located close to the areola; the nipples have between 15 and 20 lobes, of which only 5- 9 are true mammary duct orifices, there are no lactiferous sinuses, so the milk flows directly into the nipple, in terms of innervation of the breast they are innervated by the anterior and lateral cutaneous branches of the intercostal nerves. The existing evidence demonstrates the need for permanent studies in the field of morphology, as described in this review article on the breast. In different aspects, such as terms, functions and structures. This information is important for undergraduate and postgraduate training, and its use in the clinic, identification of pathologies, lactation clinics, among others.

Experiencias en lactancia materna, vivencia desde la mujer que amamanta: estudio cualitativo / Breastfeeding experiences from the perspective of the breastfeeding woman: qualitative study

Objetivos: Comprender las experiencias sobre la lactancia materna desde la perspectiva de las mujeres, en un grupo de madres lactantes primerizas. Materiales y métodos: Estudio cualitativo, bajo la perspectiva de etnografía, enfocado en un grupo de mujeres de la región oriente del departamento de Antioquia (Colombia). Por muestreo intencional y hasta la saturación de los datos se seleccionaron 16 mujeres lactantes primerizas, de 18 años o más, con hijos menores de 24 meses y que se encontraran amantando o hubiesen amantado de forma exclusiva al menos durante tres meses. Se realizaron entrevistas semiestructuradas y observación participante; el análisis de los datos se desarrolló por triangulación y codificación abierta y axial. Los resultados se presentan a través de la descripción de categorías. Resultados: Se identificaron cuatro categorías frente a la experiencia del amamantamiento: el agotamiento y el dolor que se disipan con amor, la lactancia y el nuevo orden de las cosas, las emociones de una mujer en el cuerpo de una madre y la lactancia: un acto social. Conclusiones: Proteger la lactancia materna requiere poner especial cuidado a la mujer como sujeto, más allá del amamantamiento, dando prioridad a su salud física y emocional como elementos esenciales que deben ser considerados por los profesionales en salud. Se requieren estudios que evalúen los efectos de la creación de grupos de apoyo que propicien el intercambio de saberes para acompañar a la mujer lactante

Objectives: To understand the breastfeeding experience from the perspective of a group of women who breastfeed for the first time. Material and methods: Qualitative study from an ethnographic perspective, focusing on a group of women from the eastern region of the Department of Antioquia (Colombia). Intentional sampling until data saturation was used. The group included 16 first-time breastfeeding mothers aged 18 or older, with children under 24 months of age and who were breastfeeding or had breastfed exclusively for at least three months. Semi-structured interviews and participant observations were carried out. Data were analyzed by triangulation and open and axial coding. The results are presented in the form of category descriptions. Results: Four categories were identified in relation to the breastfeeding experience: exhaustion and pain dispelled by love, breastfeeding and the new order of things, emotions of a woman embodied in a mother, and breastfeeding as a social act. Conclusions: Protection of breastfeeding requires special attention to the woman as a subject beyond the act of breastfeeding, giving priority to her physical and emotional health as essential elements that must be kept in mind by healthcare professionals. Studies to assess the effects of creating support groups that foster the exchange of insights to help the breastfeeding woman are required.

Adaptación transcultural de la encuesta de conocimientos en lactancia (ECoLa) / Cross-cultural adaptation of the Survey on Breastfeeding Knowledge (ECoLa)

Se considera fundamental el acompañamiento oportuno y actualizado del equipo de salud en el inicio y mantenimiento de la lactancia materna. Se ha documentado que algunos profesionales carecen de habilidades para ofrecer orientación adecuada a las personas lactantes, pero no existen pesquisas locales con instrumentos estandarizados acerca de sus conocimientos. Adaptar un cuestionario validado permitiría indagar y comparar estos datos con otros países, y justificaría la implementación de las estrategias educativas necesarias. El objetivo fue obtener una versión argentina de la Encuesta de Conocimientos en Lactancia (ECoLa) mediante un proceso de adaptación transcultural mediado por la participación de lingüistas, expertos en lactancia, y profesionales de medicina y enfermería como destinatarios del instrumento. La adecuación, equivalencia y comprensión fueron comprobadas en los discursos de expertos y autores, y en las respuestas de las entrevistas cognitivas. Se consiguió una versión de ECoLa equivalente a la versión original; semántica y culturalmente adaptada a profesionales argentinos.

A timely and updated support from the health care team in the initiation and maintenance of breastfeeding is essential. It has been documented that some health care providers lack the skills to offer adequate guidance to nursing mothers, but there are no local surveys on their knowledge based on standardized instruments. Adapting a validated questionnaire would allow to investigate and compare these data with those of other countries, and support the implementation of necessary educational strategies. Our objective was to obtain an Argentine version of the Survey on Breastfeeding Knowledge (Encuesta de Conocimientos en Lactancia, ECoLa) through a cross-cultural adaptation process with linguists, breastfeeding experts, physicians, and nurses. Adequacy, equivalence, and comprehension were verified in the discourses of experts and authors and cognitive interviews. A version of the ECoLa equivalent to the original version was obtained, which was semantically and culturally adapted to Argentine health care providers.

Mecanismos neuroendocrinos a la base de la asociación entre salud mental materna y lactancia / Neuroendocrine mechanisms underlying the association between maternal mental health and breastfeeding

La lactancia materna es fundamental para la salud del infante y se ve influida por diversos factores, entre ellos la salud mental materna. En particular, las madres que tienen síntomas depresivos tienen mayor riesgo de presentar dificultades de lactancia y de interrumpir tempranamente la lactancia exclusiva y la lactancia en general. Por otra parte, la lactancia materna actúa como un factor protector de la salud mental materna en algunas circunstancias, en tanto las dificultades de lactancia tienen un impacto negativo en la salud mental de la mujer. La presente revisión describe algunos de los mecanismos fisiológicos que subyacen al establecimiento y la mantención de la lactancia, asociados a la prolactina, la oxitocina, la dopamina y la serotonina, así como a la experiencia de la lactancia y la presencia de dificultades en esta área, y como estas interactúan con las dificultades emocionales de la madre. Se ofrece un modelo integrativo que considera aspectos hormonales y fisiológicos para comprender la asociación compleja y bidireccional entre el establecimiento de una lactancia exitosa y la salud mental materna.

Breastfeeding is essential for infant health and development. It is influenced by multiple factors, including maternal mental health. In particular, mothers who present depressive symptoms are at greater risk of presenting breastfeeding difficulties and presenting shorter exclusive breastfeeding and breastfeeding in general. On the other hand, breastfeeding acts as a protective factor for maternal mental health in some circumstances. Also, breastfeeding difficulties have a negative impact on womens mental health. This review describes some of the physiological mechanisms underlying the establishment and maintenance of lactation, associated with prolactin, oxytocin, dopamine, and serotonin. As well as how the lactation experience and the presence of difficulties in this area interact with the mothers emotional functioning. An integrative model is proposed, which considers hormonal and physiological aspects involved in the complex and bidirectional association between breastfeeding successful establishment and maternal mental health.

Validation of a Turkish version of the fathers' breastfeeding attitude and participation scale

SUMMARY OBJECTIVE: This study aimed to determine the validity, structure, and reliability of a Turkish version of the Fathers' Breastfeeding Attitude and Participation Scale. The Fathers' Breastfeeding Attitude and Participation Scale consists of two parts, namely, Fathers' Breastfeeding Attitude and Fathers' Participation in Breastfeeding Process. Totally, the scale consists of 28 items, of which 14 items belong to Fathers' Breastfeeding Attitude and 14 items belong to Fathers' Participation in Breastfeeding Process. There is no report of a validity and reliability study in the original scale. Currently, there is no validated and reliable scale to assess Fathers' Breastfeeding Attitudes and Involvement in Turkish literature and other languages. In this context, the psychometric properties of the Fathers' Breastfeeding Attitudes and Involvement Scale were examined. METHODS: The instruments were translated and adapted according to the WHO guidelines. RESULTS: The Turkish version of the Fathers' Breastfeeding Attitude and Participation Scale demonstrated acceptable validity and reliability. CONCLUSION: The use of the validated instrument to examine fathers' breastfeeding attitudes and participation in the breastfeeding process will provide data to guide as it is a determinant of breastfeeding behavior.

Evaluación de ingesta dietética en un grupo de mujeres lactantes en dos poblaciones de Antioquia, Colombia, 2021-2022 / Dietary intake assessment in a group of breastfeeding women in two populations of Antioquia, Colombia, 2021-2022

Objetivos: Describir la prevalencia del riesgo de deficiencia o exceso en la ingesta de nutrientes y el patrón de consumo de alimentos de acuerdo con las recomendaciones establecidas por el Ministerio de Salud y Protección Social y el Instituto Colombiano de Bienestar Familiar. Materiales y métodos: Se realizó un estudio transversal descriptivo en mujeres sanas que fueron atendidas en dos hospitales del oriente antioqueño, con seguridad alimentaria y nutricional (SAN) según la Escala Latinoamericana y Caribeña de Seguridad Alimentaria (ELCSA), en el primer trimestre de lactancia, evaluadas entre los años 2021 y 2022. La fuente de información fue la historia clínica. Se midieron las características sociodemográficas, clínicas, antropométricas y la ingesta dietética y de micronutrientes. Se empleó estadística descriptiva. Se presenta la prevalencia de déficit o exceso de ingesta calórica y el índice de relación de consumo (IRC). Se utilizaron los software EVINDI v5, PC-SIDE v1.0, Stata 16.1 y Jasp 0.16.4. Resultados: Se incluyeron 30 mujeres lactantes. La prevalencia de riesgo de deficiencia en la ingesta usual de energía fue 43 % y exceso 16 %; el riesgo de deficiencia proteica fue 98 %. El consumo superior al valor de referencia para grasa saturada fue 86 % y carbohidratos simples 72 %. El patrón de consumo se caracterizó por superar las recomendaciones para azúcares (IRC = 1,29), leche y derivados (IRC = 1,09), cereales, raíces, plátanos y tubérculos (IRC = 1,04). No cumplieron las recomendaciones en la ingesta de grasas (IRC = 0,70), carnes, huevos, leguminosas, frutos secos y semillas (IRC = 0,49), frutas y verduras (IRC = 0,41). Conclusiones: El patrón alimentario identificado dista de las guías nacionales, lo que limita el consumo de macro y micronutrientes, y contribuye al círculo intergeneracional de la malnutrición. Es fundamental realizar nuevas investigaciones en el país para identificar otros patrones de consumo e impulsar acciones de política al respecto.

Objectives: To describe the prevalence of the risk of under or overnutrition and the food intake pattern vis á vis the recommendations of the Ministry of Health and Social Protection and the Colombian Family Welfare Institute. Material and methods: Descriptive cross-sectional study carried out in healthy women receiving care in two hospitals of eastern Antioquia, with food and nutrition security in accordance with the Latin American and Caribbean Food Security Scale (ELCSA), in the first trimester of breastfeeding, assessed between 2021 and 2022. The clinical record was used as the source of information. The sociodemographic, clinical, anthropometric characteristics, as well as dietary and micronutrient intake, were measured. Descriptive statistics were used. The prevalence of deficient or excessive energy intake and the food consumption score (FCS) are presented. The EVINDI v5, PC-SIDE v1.0, Stata 16.1 and Jasp 0.16.4 software packages were used. Results: Overall, 30 breastfeeding women were included. The prevalence of the risk of deficient energy intake was 43 %, while the risk of excessive intake was 16 % and the risk of protein deficiency was 98 %. Intake exceeding the reference value for saturated fats was 86 %, and 72 % for simple carbohydrates. The consumption pattern was characterized by exceeding the recommendations for sugars (FCS = 1.29), milk and dairy products (FCS = 1.09), grains, roots, plantains and tubers (FCS = 1.04). Recommendations for the intake of fats (FCS = 0.70), meats, eggs, legumes, nuts, seeds (FCS = 0.49), fruits and vegetables (FCS = 0.41) were not met. Conclusions: The food intake pattern identified is far from meeting the national guidelines, limiting macro and micronutrient intake and contributing to the intergenerational malnutrition cycle. Additional research in the country is essential in order to identify other intake patterns and drive political action.

Lactancia materna exclusiva y trabajo. Su importancia en la medicina del trabajo / Exclusive breastfeeding and work. Its importance in occupational health

En todos los ámbitos laborales, sin excepción, es imprescindible la vigencia ineludible del derecho irrestricto de toda madre a ejercer, practicar, su lactancia con su bebé. Y las razones médicas debieran formar parte de campañas incesantes para que este derecho de las mamás esté absolutamente naturalizado en todos los niveles y en cada rincón del país. La lactancia materna protege al bebé de enfermedades infecciosas y le da la nutrición ideal para una vida más sana. Es fundamental desde el primer día de vida extrauterina hasta los 6 meses con exclusividad y luego continúa con suplementos vitamínicos y nutrientes apropiados. En todo lugar de trabajo deben existir lactarios como una estrategia de Salud Pública y en Medicina del Trabajo. (AU)

In all areas of work, without exception, the unavoidable validity of the unrestricted right of every mother to exercise, practice, breastfeeding with her baby is essential. And the medical reasons should be part of incessant campaigns so that this right of mothers is absolutely naturalized at all levels and in every corner of the country. Breastfeeding protects the baby from infectious diseases and gives it the ideal nutrition for a healthier life. It is essential from the first day of extrauterine life until 6 months exclusively and then continues with appropriate vitamin and nutrient supplements. In every workplace there must be lactation rooms as a strategy of Public Health and Occupational Medicine. (AU)

Factors associated with breastfeeding abandonment in the first month after the mother's return to work / Fatores associados ao abandono do aleitamento materno no primeiro mês após o retorno da lactante ao trabalho

Abstract The return to work of lactating mothers has been identified as an important risk factor for breastfeeding interruption. We proposed to identify factors associated with breastfeeding abandonment in the first month after return. 252 women working at a hospital who had children aged 12 to 36 months and who were still breastfeeding when returned to work answered a questionnaire containing questions on sociodemographic characteristics, pregnancy, childbirth, breastfeeding and work-related factors. The associations were estimated using adjusted prevalence ratio (aPR), calculated with the hierarchical Poisson multivariable regression model. The following factors showed a significant association with breastfeeding abandonment: using a pacifier (aPR 4.58), cohabiting with someone other than partner (aPR 3.77), having no intention or having doubts about maintaining breastfeeding after returning (aPR 3.39), having a college degree (aPR 2.66), having no support from the infant's caregiver (aPR 2.26), and infant being older when the woman returned to work (PR 1.16 for each additional month of infant age). Longer duration of exclusive breastfeeding was a protective factor (aPR 0.990). Most of the factors associated with discontinuation of breastfeeding in the first month after the mother's return to work are not directly related to the woman's work.

Resumo O retorno da lactante ao trabalho é apontado como importante fator de risco para interrupção da amamentação. Nós nos propusemos a identificar fatores associados ao abandono da amamentação no primeiro mês após o retorno. Compuseram a amostra 252 servidoras de um hospital com filhos entre 12 e 36 meses e que estavam amamentando quando retornaram ao trabalho, fornecendo informações sobre características sociodemográficas, gestação, parto, amamentação e fatores relacionados ao trabalho. As associações foram estimadas pela razão de prevalência ajustada (RPa), obtida usando modelo hierárquico de regressão multivariada de Poisson. Os seguintes fatores mostraram associação significativa com abandono da amamentação: uso de chupeta (RPa 4,58), coabitação com outra pessoa que não o companheiro (RPa 3,77), não ter intenção ou ter dúvidas sobre amamentar após retorno (RPa 3,39), ter curso superior (RPa 2,66), não ter apoio do cuidador da criança (RPa 2,26) e maior idade da criança quando a mãe retornou ao trabalho (RPa 1,16 para cada mês de idade a mais da criança). Maior duração da amamentação exclusiva foi fator de proteção (RPa 0,990). A maioria dos fatores associados à descontinuidade da amamentação no primeiro mês após retorno da lactante ao trabalho não está diretamente relacionada ao seu trabalho.
