Objective:
To analyze the correlation between breastfeeding in the first hour of life with neonatal mortality rates.
Methods:
The present study used secondary data from 67 countries, obtained from the Demographic and Health Surveys. Initially, for data analysis, Spearman Correlation (95% CI) and Kernel graphical analysis were employed, followed by a Negative Binomial Pois- son regression model, adjusted for potential confounders.
Results:
Breastfeeding within the first hour of life was negatively correlated with neo- natal mortality (Spearman's Rho = -0.245, p = 0.046), and this correlation was stronger among countries with more than 29 neonatal deaths per 1000 newborns (Spearman's Rho = -0.327, p = 0.048). According to the statistical model, countries with the lowest breastfeeding tertiles had 24% higher neonatal mortality rates (Rate ratio = 1.24, 95% CI = 1.07-1.44, p < 0.05), even when adjusted for potential confounders.
Conclusion:
The protective effect of breastfeeding during the first hour of life on neo- natal mortality in this ecological study is consistent with findings from previous observa- tional studies, indicating the importance of adopting breastfeeding within the first hour as a routine neonatal care practice.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
