RESUMEN
BACKGROUND: Exclusive breastfeeding (EBF) remains the cornerstone of infant nutrition for the first six months of life, presenting multiple short and long term benefits. The purpose of this study is the demonstration of EBF rates of infants born in baby-friendly hospitals (BFH) and the factors that positively influence EBF. METHODS: The study was conducted in all four of the BFH that exist in Greece, between 2020 and 2022. The study sample consisted of 1200 mothers, taken from the 7101 that delivered at those hospitals during the time of the study. A questionnaire was used that included questions to evaluate the infant's nutrition after birth, after exiting the maternity hospital and during the 2nd, 4th and 6th month of age. The WHO guidelines on EBF and breastfeeding (BF), as well as the "Infant and Young Child Feeding" indicators, were used. RESULTS: The EBF rate within 1 h after birth was 71.3%, which gradually declined to 21.2% in the 6th month. The respective rate of BF was 94.5% and declined to 66.1%. The logistic regression revealed that attending antenatal breastfeeding courses, vaginal delivery, full-term pregnancies and the mothers' advanced education level constitute independent positive prognostic factors for increased EBF rates. CONCLUSION: The results of the first national study on BFH are presented. Despite the improvement of EBF rates in Greece, compared to the latest available data from 2018, reinforcement of EBF promotion measures is required in order to approach the WHO's targets by 2025.
RESUMEN
The detection of NT-proBNP levels both in umbilical cord blood (UCB) samples and in serum samples collected from healthy term neonates during the neonatal period. A systematic review of relevant literature in accordance with PRISMA guidelines was conducted. For quality appraisal, the potential risk of bias was assessed using the BIOCROSS evaluation tool. The random-effects and fixed-effects models were used to calculate weighted mean differences with a corresponding 95% confidence interval. A total of forty (40) studies met the inclusion criteria for the systematic review. After further examination, eighteen (18) studies (1738 participants) from the UCB sample group and fourteen (14) studies (393 participants) from the serum sample group were selected to perform a meta-analysis. Using the fixed-effects model, the mean intervals of NT-proBNP in UCB and serum samples were 492 pg/mL (95% CI: 480−503 pg/mL) and 1341 pg/mL (95% CI: 1286−1397 pg/mL), respectively. A higher concentration of ΝΤ-proBNP was observed in the serum sample group compared to the UCB samples (p < 0.001). We present the intervals of NT-proBNP in UCB and in the serum of healthy term neonates. The determination of the potential effect of perinatal factors on the biomarker's reference range was also aimed.
