Abstract: Introduction: Human milk banks support breastfeeding and the provision of donor milk to newborns who need this care. Objective: To analyze annual trends in donor and recipient records and in milk volumes collected and distributed by the human milk bank in Guarapuava, Paraná, Brazil, from 2014 to 2023. Methods: This ecological time-series study used ten annual observations per indicator obtained from the service’s production reports. Indicators were the monthly mean numbers of donors and recipients and annual milk volumes in liters. Prais–Winsten regression was applied to log10-transformed indicators to estimate annual percentage changes (APCs), 95% confidence intervals (95% CIs), and Holm-adjusted p-values for four tests. Results: The service collected 6,989.90 L and distributed 4,529.70 L. Recipient records increased (APC: 9.29%; 95% CI: 3.84 to 15.02; adjusted p=0.016), as did milk distributed (8.61%; 95% CI: 3.22 to 14.28; adjusted p=0.017). Adjusted p-values for donors and milk collected were 0.778 and 0.098, respectively. In a sensitivity analysis excluding 2014, only recipients retained evidence of growth after adjustment. Conclusion: Recipient records showed consistent annual growth in both analyses. Growth in milk distributed was sensitive to the period analyzed. Production indicators do not establish seasonality, causes of change, or milk quality.
