Actual electrolyte intake during the first week of life and morbidity in very-low-birthweight infants.

AIM: To describe sodium and potassium intake, their sources and plasma concentrations, and the association between intake and morbidity in very-low-birthweight (VLBW, <1500 g) infants during the first week of life. METHODS: This retrospective cohort study comprised 951 VLBW infants born at <32 weeks. Infants were divided into three groups according to gestational age: 23-26 (n = 275), 27-29 (n = 433) and 30-31 (n = 243) weeks. Data on fluid management and laboratory findings were acquired from an electronic patient information system. RESULTS: The median sodium intake was highest in the 23-26 week group, peaking at 6.4 mmol/kg/day. A significant proportion of sodium derived from intravascular flushes; it reached 27% on day 1 in the 23-26 week group. High cumulative sodium intake in the first postnatal week was associated with weight gain from birth to day 8 in the 23-26 week group. High intake of sodium associated with an increased risk of surgically ligated patent ductus arteriosus (PDA), bronchopulmonary dysplasia and intraventricular haemorrhage, whereas low intake of potassium associated with an increased risk of PDA. CONCLUSION: Sodium intake in the most premature infants exceeded recommendations during the first postnatal week. Saline flushes accounted for a significant proportion of the sodium load.

Risk factors for acute kidney injury in very-low birth weight newborns: a systematic review with meta-analysis.

This study aims to analyze the main risk factors for acute kidney injury in the subgroup of very-low birth weight newborns, using the diagnosing criteria of the Kidney Disease Improving Global Outcomes (KDIGO) or the Acute Kidney Injury Network (AKIN). A systematic review of the literature was performed on the EMBASE® and PubMed® platforms. Studies that evaluated the risk factors for developing AKI in VLBW newborns were included. For the meta-analysis, we only included the risk factors that were associated with AKI in the univariate analysis of at least two studies. After an initial screening, abstract readings, and full-text readings, 10 articles were included in the systematic review and 9 in the meta-analysis. The incidence of AKI varied from 11.6 to 55.8%. All the studies have performed multivariate analysis, and the risk factors that appeared most were PDA and hemodynamic instability (use of inotropes or hypotension), sepsis, and invasive mechanical ventilation. After the meta-analysis, only cesarian delivery did not show an increased risk of AKI, all the other variables remained as important risk factors. Moreover, in our meta-analysis, we found a pooled increased risk of death in newborns with AKI almost 7 times.  Conclusion: AKI in VLBW has several risk factors and must be seen as a multifactorial disease. The most common risk factors were PDA, hemodynamic instability, sepsis, and invasive mechanical ventilation. What is known: • Acute kidney injury is associated with worst outcomes in all ages. It´s prevention can help diminish mortality. What is new: • A synthesis of the main risk factors associated with AKI in very low birth weight newborns.

Changes in parents' health concerns by post-preterm birth period in South Korea: a cross-sectional study.

PURPOSE: This study aimed to examine the health concerns of parents regarding their premature infants and to identify changes in these concerns during perinatal period and after discharge. METHODS: This was a retrospective study performed at a single tertiary center that enrolled 119 premature infants who were discharged from the neonatal intensive care unit (NICU) and visited the outpatient pediatrics department between December 2018 and October 2021. Data on the concerns of 176 parents regarding enrolled premature infants' health from before birth to 1 week after NICU discharge were obtained from outpatient records. The t test and with the chi-squared test were used to analyze the data for this study. RESULTS: The consistently greatest focus of parents' health concerns was the respiratory system. The second focus of parents' health concerns before discharge was the central nervous system. However, during the first week after NICU discharge, the gastrointestinal system was the second-most frequent focus of parents' health concerns among parents of infants without diseases related to prematurity and infants with older gestational ages. CONCLUSION: The results of this study offer insights into the health concerns among parents of premature infants. Parental health concerns about premature infants vary over time, from before birth to post-discharge, necessitating supportive interventions to enhance parental understanding of their child's health status.

Personalized lung care: Bronchopulmonary dysplasia risk prediction tool tailored for neonates born in resource-limited settings.

PURPOSE: Predicting bronchopulmonary dysplasia (BPD) to assess the risk-benefit of therapy is necessary considering the side effects of medications. We developed and validated an instrument for predicting BPD and compared it with an instrument currently used for neonates born in a Brazilian hospital. METHODS: This was a retrospective cohort study of patients born between 2016 and 2020 with a gestational age (GA) between 23 and 30 weeks. Predictive equations were elaborated using methods of component variable selection collected on the 14th day of life; 70% of the sample was randomly selected for the construction of risk prediction equations and the remaining 30% for their validation, application, and comparison with the National Institute of Child Health and Human Development (NICHD) instrument. The sensitivity, specificity, and predictive values of the equations were calculated. RESULTS: The equation that used variables with p < 5% in Fisher's exact test presented the best results: specificity of 98% and positive predictive value of 93% and could be used for BPD prediction of all small-for-gestational-age (SGA) infants. The NICHD calculator applied to our population had a specificity of 93% and a positive predictive value of 75% and could not be applied to extremely SGA infants. CONCLUSION: Our tool can predict the risk of BPD on the 14th day of life, has higher specificity and positive predictive value to our population than the NICHD instrument, and can be suitable for SGA infants. The results must be confirmed by applying it to other populations to validate our tool.

Screening and prevention of preterm birth: how is it done in clinical practice?

Objective: To ascertain how screening for preterm birth is performed among obstetricians working in public and private practice in a middle-income country. Methods: Cross-sectional study of 265 obstetrician-gynecologists employed at public and private facilities. An online questionnaire was administered, with items designed to collect data on prematurity screening and prevention practices. Results: The mean age of respondents was 44.5 years; 78.5% were female, and 97.7% had completed a medical residency program. Universal screening (i.e., by ultrasound measurement of cervical length) was carried out by only 11.3% of respondents in public practice; 43% request transvaginal ultrasound if the manual exam is abnormal, and 74.6% request it in pregnant women with risk factors for preterm birth. Conversely, 60.7% of respondents in private practice performed universal screening. This difference in screening practices between public and private practice was highly significant (p < 0.001). Nearly all respondents (90.6%) reported prescribing vaginal progesterone for short cervix. Conclusion: In the setting of this study, universal ultrasound screening to prevent preterm birth was used by just over half of doctors in private practice. In public facilities, screening was even less common. Use of vaginal progesterone in cervical shortening was highly prevalent. There is an unmet need for formal protocols for screening and prevention of preterm birth in middle-income settings.

Neurally adjusted ventilatory assist in preterm infants: A systematic review and meta-analysis.

To compare the effects of neurally adjusted ventilatory assist (NAVA) with other forms of synchronized artificial ventilation in preterm infants. A systematic review of randomized and quasi-randomized controlled trials with individual group allocation, both parallel-group trials as well as crossover trials, that included preterm infants born at less than 37 weeks gestational age and compared NAVA with any other form of synchronized mechanical ventilation with or without volume guarantee. Primary outcomes were death or bronchopulmonary dysplasia (BPD) at 36 weeks, total duration of respiratory support and neurodevelopmental outcome at 2 years. Secondary outcomes consisted of important procedural and clinical outcomes. Seven studies with a total of 191 infants were included, five randomized crossover trials and two parallel group randomized trials. No significant difference in the primary outcome of death or BPD (RR: 1.08, 95% CI: 0.33-3.55) was found. Peak inspiratory pressures were significantly lower with NAVA than with other forms of ventilation (MD -1.83 cmH2O [95% CI: -2.95 to -0.71]). No difference in any other clinical or ventilatory outcome was detected. Although associated with lower peak inspiratory pressures, the use of NAVA does not result in a reduced risk of death or BPD as compared to other forms of synchronized ventilation in preterm infants. However, the certainty of evidence is low due to imprecision of the effect estimate. Larger studies are needed to detect possible short- and long-term differences between ventilation modes.

Tuberculosis in pregnancy and adverse neonatal outcomes in two peruvian hospitals.

Background: According to the World Health Organization, tuberculosis (TB) ranks among the top 10 causes of death worldwide. The significance of TB during pregnancy lies in its symptoms, which can be mistaken for physiological changes associated with pregnancy. This confusion can lead to maternal-perinatal complications. Objective: To evaluate the association between pulmonary TB in pregnancy and adverse neonatal outcomes in two Peruvian hospitals. Methods: This is a retrospective cohort study. The target population consisted of pregnant women with and without pulmonary TB whose deliveries were attended at two public hospitals, located in Lima, Peru. The adverse neonatal outcomes were prematurity, low birth weight (LBW), and being small for gestational age (SGA). Crude and adjusted relative risks (RRa) were calculated with their respective 95% confidence intervals (95%CI). Results: Information from 212 patients was analyzed; 48.1% had TB during pregnancy, and 23.1% had adverse neonatal outcomes (8%, 11.3%, and 12.3% for LBW, prematurity, and SGA, respectively). In the adjusted model, pregnant women with pulmonary TB had a 3.52 times higher risk of having a newborn with at least one of the adverse outcomes than those who were not exposed (aRR, 3.52; 95%CI: 1.93-6.68). Conclusion: Pulmonary TB in pregnancy was jointly and independently associated with adverse neonatal outcomes, including LBW, prematurity, and being SGA.

Kangaroo care: Benefits, challenges, and future perspectives in neonatal care. An integrative review / Método canguro: Beneficios, desafíos y perspectivas futuras en el cuidado neonatal. Una revisión integrativa / Cuidado canguru: benefícios, desafios e perspectivas futuras na assistência neonatal. Uma revisão integrativa

Objective: To review current scientific evidence on the physiological effects of kangaroo care, explore barriers and facilitators to its implementation, and identify areas requiring further research. Materials and methods: An integrative review was conducted using PubMed, Scopus, Web of Science, and Cochrane databases without language restrictions. Studies included quantitative and qualitative review studies. Critical appraisal of studies was performed using the Joanna Briggs Institute tool. Results: Sixteen studies were analyzed, providing heterogeneous support for the efficacy of kangaroo care  in improving various neonatal physiological parameters including heart rate, body temperature, and oxygen saturation. Major barriers to implementation included restricted visiting hours, healthcare staff workload, negative cultural beliefs, lack of information and empowerment for mothers, and limited involvement of fathers. Conclusions: kangaroo care positively impacts premature or low birth weight neonatal development, though implementation is influenced by sociocultural factors. Further research is needed to better assess real effects on neonatal physiological parameters. Additional qualitative studies could aid in developing culturally adapted strategies to optimize kangaroo care implementation across contexts by better understanding family and medical team perspectives.

Oropharyngeal colostrum immunotherapy and risk reduction of mortality in very low birth weight premature newborns: a clinical trial.

OBJECTIVE: To evaluate the effect of oropharyngeal colostrum immunotherapy (OCI) on the mortality of preterm newborns (PTNB) with very low birth weight (VLBW). METHOD: Non-randomized clinical trial, carried out with 138 mother-child pairs attended at a public maternity hospital. The treatment group used raw colostrum, dripping 4 drops (0.2 ml) into the oropharyngeal mucosa, totaling 8 administrations in 24 h, up to the 7th complete day of life (OCI). The control group was composed of newborns admitted to the same maternity hospital before the implementation of the OCI. Analyzes were performed: descriptive, bivariate, multiple logistic regression, and survival analysis, with a significance level of 5% and 95% CI. RESULTS: The treatment group had an RR of death of 0.26 (95% CI = 0.07-0.67; p = 0.00), adjusted for maternal age, marital status, gestational hypertension, type of delivery, number of prenatal visits, and birth weight. Number Needed to Treat (NNT) demonstrated that for every 5 individuals treated with OCI, one death was prevented NNT = 4.9 (95% CI = 1.84-5.20); however, for PTNB with VLBW who remained hospitalized for 50, 100 and 150 days, the NNT reduces to 4, 4 and 3, respectively. CONCLUSION: The OCI proved to be a beneficial intervention, since it reduced the risk of mortality in PTNB with VLBW when compared to the control group.

Effects of land cover and air pollution on the risk of preterm births / Efeitos da cobertura de solo e poluição do ar no risco de nascimentos prematuros

ABSTRACT OBJECTIVE To evaluate the association between gestational age and green areas, urban built areas, and the concentration of particulate matter 2.5 (PM2.5) in the city of São Paulo, analyzing the irregular distribution of these areas and pollution levels above the recommended level. METHODS The study population consisted of a cohort of live births from 2012, and data from the Live Birth Information System (Sinasc) of the city of São Paulo were used. Using satellite images and supervised classification, the distribution and quantity of green areas and built areas in the city of São Paulo was obtained, as well as the concentrations of PM2.5. Logistic regressions were used to obtain possible associations. RESULTS The results of the study show that a lower percentage of green areas is significantly associated with a higher chance of preterm births. A higher building density was positively associated with the odds ratio for preterm birth. We did not find any significant associations between air pollution (PM2.5) and preterm births. CONCLUSIONS The results of this study show that greener areas are less associated with preterm births when compared with less green areas.

RESUMO OBJETIVO Avaliar a associação entre a idade gestacional e as áreas verdes, áreas construídas urbanas e a concentração de material particulado 2,5 (MP2,5) em São Paulo, analisando a distribuição irregular dessas áreas e os níveis de poluição acima do recomendado. MÉTODOS A população utilizada no estudo foi a dos nascidos vivos no ano de 2012, com os dados do Sistema de Informações sobre Nascidos Vivo (Sinasc) na cidade de São Paulo. Por meio de imagens de satélites e realizando a classificação supervisionada, obtivemos a distribuição e quantidade de áreas verdes e de áreas construídas, na cidade de São Paulo, assim como as concentrações de MP2,5. Regressões logísticas foram utilizadas para obter possíveis associações. RESULTADOS Os resultados do estudo mostram que menor percentual de áreas verdes está associado significativamente com maior chance de prematuridade. Maior densidade de construção foi associada positivamente com a razão de chance de nascimento prematuro. Não encontramos resultados significativos entre a poluição do ar (MP2,5) e prematuridade. CONCLUSÕES Os resultados deste estudo demostraram que áreas mais verdes em relação às áreas menos verdes são menos associadas a nascimentos prematuros.

Cognitive assessment in preterms by Bayley-III: development in the first year and associated factors / Avaliação cognitiva em crianças pré-termo usando Bayley-III: desenvolvimento no primeiro ano de vida e fatores associados

ABSTRACT Objective: To analyze the cognitive development of preterm infants at six and 12 months of corrected age and the associations with perinatal and socioeconomic factors. Methods: Cognitive development of 40 infants (20 preterm and 20 full-term) at six and 12 months of age was evaluated using the Bayley-III scale. Correlations between cognitive outcome and associated factors were assessed using Spearman correlation. Stepwise multiple linear regression analysis with covariance was applied to identify changes on cognitive score between six and 12 months. Results: Bayley-III cognitive score in preterm group was significantly lower than in full-term group at both six and 12 months of age. Birth weight correlated with cognitive performance at six months and head circumference at birth at 12 months, in full-terms infants. The occurrence of necrotizing enterocolitis was inversely associated with cognitive score in preterms at 12 months. An increase in cognitive score was observed between six and 12 months in both groups, but the gain was more pronounced in preterms. Conclusions: These findings suggest some cognitive recovery capacity in the first year despite the restrictions imposed by premature birth and emphasize the importance of early interventions in this population.

RESUMO Objetivo: Avaliar o desenvolvimento cognitivo de crianças pré-termo aos seis e 12 meses de idade corrigida e as associações com fatores perinatais e socioeconômicos. Métodos: O desenvolvimento cognitivo de 40 crianças (20 pré-termo e 20 a termo) foi avaliado aos seis e 12 meses de idade, utilizando a escala Bayley-III. Correlações entre resultados cognitivos e fatores associados foram avaliadas pelo teste de correlação de Spearman. A análise de regressão linear múltipla stepwise com covariância foi aplicada para identificar mudanças na pontuação cognitiva entre seis e 12 meses. Resultados: O escore cognitivo no grupo pré-termo foi significativamente menor que no grupo a termo aos seis e 12 meses. O peso ao nascer foi diretamente associado com o desempenho cognitivo aos seis meses e perímetro cefálico ao nascimento aos 12 meses, nas crianças a termo. A ocorrência de enterocolite necrosante foi inversamente associada ao desempenho cognitivo em pré-termos, aos 12 meses. Verificou-se aumento na pontuação cognitiva entre seis e 12 meses nos dois grupos, porém mais pronunciado no pré-termo. Conclusões: O estudo sugere que crianças pré-termo apresentam alguma capacidade de recuperação cognitiva no primeiro ano, apesar das restrições impostas pelo nascimento prematuro, e enfatizam a importância de acompanhamento dessa população desde os primeiros meses de vida.

Oropharyngeal colostrum immunotherapy and risk reduction of mortality in very low birth weight premature newborns: a clinical trial

Abstract Objective To evaluate the effect of oropharyngeal colostrum immunotherapy (OCI) on the mortality of preterm newborns (PTNB) with very low birth weight (VLBW). Method Non-randomized clinical trial, carried out with 138 mother-child pairs attended at a public maternity hospital. The treatment group used raw colostrum, dripping 4 drops (0.2 ml) into the oropharyngeal mucosa, totaling 8 administrations in 24 h, up to the 7th complete day of life (OCI). The control group was composed of newborns admitted to the same maternity hospital before the implementation of the OCI. Analyzes were performed: descriptive, bivariate, multiple logistic regression, and survival analysis, with a significance level of 5% and 95% CI. Results The treatment group had an RR of death of 0.26 (95% CI = 0.07-0.67; p= 0.00), adjusted for maternal age, marital status, gestational hypertension, type of delivery, number of prenatal visits, and birth weight. Number Needed to Treat (NNT) demonstrated that for every 5 individuals treated with OCI, one death was prevented NNT = 4.9 (95% CI = 1.84-5.20); however, for PTNB with VLBW who remained hospitalized for 50, 100 and 150 days, the NNT reduces to 4, 4 and 3, respectively. Conclusion The OCI proved to be a beneficial intervention, since it reduced the risk of mortality in PTNB with VLBW when compared to the control group.

Transição alimentar de prematuros internados na Unidade Canguru: revisão sistemática / Transición alimentaria de prematuros internados en la Unidad Canguro: revisión sistemática / Food transition of premature infants admitted to the Kangaroo Unit: systematic review

Resumo Objetivo Analisar as evidências disponíveis sobre a transição alimentar de sonda orogástrica para aleitamento materno diretamente na mama com prematuros internados em unidades hospitalares. Métodos Revisão sistemática da literatura com busca nas bases de dados PubMed/MEDLINE, Web of Science, EMBASE, Scopus, Cochrane CENTRAL, CINAHL, com os critérios de inclusão: estudos experimentais, sem restrição temporal e nos idiomas português, espanhol e inglês. A avaliação metodológica foi realizada por meio das ferramentas Grading of Recommendations Assessment, Development and Evaluation (GRADE) e Revised Cochrane risk-of-bias tool for randomized trials (RoB 2.0) e consistiu em duas etapas: qualidade metodológica e o risco de viés dos estudos. Resultados Foram identificados 10 artigos, todos ensaios clínicos randomizados. As técnicas utilizadas na transição da dieta dos prematuros encontradas foram: sonda-dedo e seringa, copo e sonda-dedo, copo e mamadeira, colher e sucção não-nutritiva, sucção não-nutritiva, sucção não-nutritiva e estimulação oral, comportamento dos prematuros, cheiro do leite materno. Conclusão As técnicas evidenciadas permitiram a transição da dieta, em um período mais curto, reduzindo o tempo de internação, aumentando o ganho de peso e se mostraram seguras, desde que o prematuro tenha maturidade para ser realizada. Contudo, a mamadeira foi desaconselhada, pela ocorrência de episódios de dessaturação, aumento da frequência cardíaca e confusão de bico.

Resumen Objetivo Analizar las evidencias disponibles sobre la transición alimentaria de sonda orogástrica a lactancia materna directamente de la mama con prematuros internados en unidades hospitalarias. Métodos Revisión sistemática de la literatura con búsqueda en las bases de datos PubMed/MEDLINE, Web of Science, EMBASE, Scopus, Cochrane CENTRAL, CINAHL, con los siguientes criterios de inclusión: estudios experimentales, sin restricción temporal y en idioma portugués, español e inglés. La evaluación metodológica se realizó por medio de las herramientas Grading of Recommendations Assessment, Development and Evaluation (GRADE) y Revised Cochrane risk-of-bias tool for randomized trials (RoB 2.0) y consistió en dos etapas: calidad metodológica y riesgo de sesgo de los estudios. Resultados Se identificaron 10 artículos, todos ensayos clínicos aleatorizados. Las técnicas utilizadas para la transición de la dieta de prematuros fueron: dedo-jeringa y jeringa, vaso y dedo-jeringa, vaso y mamadera, cuchara y succión no nutritiva, succión no nutritiva, succión no nutritiva y estimulación oral, comportamiento de los prematuros, olor de la leche materna. Conclusión Las técnicas observadas permitieron realizar la transición de la dieta en un período más corto, con reducción del tiempo de internación y mejor aumento de peso y demostraron ser seguras, siempre que el prematuro tenga madurez para realizarlas. No obstante, se desaconseja la mamadera por la presencia de episodios de desaturación, aumento de la frecuencia cardíaca y confusión tetina-pezón.

Abstract Objective To analyze the available evidence on the transition from orogastric tube feeding to breastfeeding directly from the breast with premature infants admitted to hospital units. Methods Systematic literature review with search in the following databases: PubMed/MEDLINE, Web of Science, EMBASE, Scopus, Cochrane CENTRAL, CINAHL, with the inclusion criteria: experimental studies, without temporal restrictions and in Portuguese, Spanish and English. The methodological assessment was carried out using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) and Revised Cochrane risk-of-bias tool for randomized trials (RoB 2.0) tools and consisted of two stages: methodological quality and the risk of bias of the studies. Results 10 papers were identified, all randomized clinical trials. The techniques used in transitioning the premature babies' diet were: finger tube and syringe, cup and finger tube, cup and bottle, spoon and non-nutritive sucking, non-nutritive sucking, non-nutritive sucking and oral stimulation, behavior of premature babies, and smell of breast milk. Conclusion The demonstrated techniques allowed the transition of the diet in a shorter period, reducing the length of hospital stay, increasing weight gain 1and proved to be safe, as long as the premature baby is mature enough to undergo the procedure. However, bottle feeding was not recommended due to the occurrence of episodes of desaturation, increased heart rate and nipple confusion.

Weaknesses in the continuity of care for preterm infants discharged from the neonatal unit / Debilidades en la continuidad de la atención a los recién nacidos prematuros egresados de la unidad neonatal / Fragilidades para a continuidade do cuidado ao pré-termo egressoda unidade neonatal

ABSTRACT Objective: To identify weaknesses in the continuity of care for preterm infants discharged from a neonatal unit, based on the perspective of professionals in the family health strategy. Method: Qualitative research, carried out with 16 professionals from four health regions in a capital city in the center-west of Brazil. Data collection took place from October to December 2020, through semi-structured, individual, and in-person interviews. Data underwent content analysis, supported by the concept of continuity of care. Results: The analysis consisted of three categories: Challenges for care in the unit and referral to specialized services; weak interactions between the preterm baby's family and health professionals; Information: essential aspect for the connection between health professionals and the family of the preterm newborn. Conclusion: Health services are shown to be fragile in terms of the dimensions of continuity of care, contributing to the discontinuity of care for preterm children.

Relação do tipo de contacto físico com o aleitamento materno exclusivo na alta hospitalar / Association between the type of physical contact and exclusive breastfeeding at hospital discharge / Relación del tipo de contacto físico con la lactancia materna exclusiva en el momento del alta hospitalaria

Resumo Enquadramento: Promover o contacto físico, especialmente o pele a pele, de forma imediata ou precoce em recém-nascidos prematuros é ainda um desafio. Objetivo: Verificar a prevalência de contacto físico entre mãe e recém-nascido prematuro no nascimento e associar o tipo de contacto físico realizado pelo binómio na sala de parto com a prevalência do aleitamento materno exclusivo na alta hospitalar. Metodologia: Estudo transversal com amostra não probabilística de 78 mães e 79 prematuros. A colheita de dados foi efetuada de julho a novembro de 2017, por meio de entrevista e consulta em prontuário e os dados foram analisados conforme a estatística descritiva e Regressão de Poisson com variância robusta. Resultados: A prevalência de qualquer tipo de contacto físico realizado na sala de parto foi de 51,9%, sem diferença estatística entre o tipo de contacto físico realizado entre mãe e bebé com o aleitamento materno exclusivo na alta. Conclusão: O contacto físico pelo toque e beijo no momento do parto não influenciou na prevalência de aleitamento materno exclusivo na alta hospitalar.

Abstract Background: Promoting physical contact, especially skin-to-skin contact, immediately or as soon as possible in preterm newborns is still a challenge. Objective: To determine the prevalence of physical contact between mothers and preterm newborns at birth and to analyze the association between the type of physical contact between them in the delivery room and the prevalence of exclusive breastfeeding at hospital discharge. Methodology: Cross-sectional study with a nonprobability sample of 78 mothers and 79 preterm newborns. Data were collected from July to November 2017, through interviews and medical records, and analyzed through descriptive statistics and Poisson Regression with robust variance. Results: The prevalence of any type of physical contact in the delivery room was 51.9%, without statistical difference between the type of physical contact between mothers and infants and exclusive breastfeeding at discharge. Conclusion: Physical contact by touching and kissing after birth did not influence the prevalence of exclusive breastfeeding at hospital discharge.
