Background: Noncompliance with child support payments has a negative impact on the protection of children, increasing the risk of malnutrition and food insecurity. Family relationships and trust in the justice system can also be affected. Objective: To describe the characteristics of monthly child support debts in Peru, according to the geographic area and jurisdiction of the judicial authority. Materials and Methods: A cross-sectional study was conducted by analyzing the cases of child support debt from 2019, according to the Register of Delinquent Child Support Debtors (REDAM) of the Judiciary of Peru. A descriptive analysis of child support debt by region and jurisdiction of the judicial authority was carried out. Results: 750 records of child support debtors were included, and it was identified that only 0.53% of the debtors paid off their debt. Differences were found in child support debt between the regions of Peru. Human development indicators and vulnerability to food insecurity had a similar trend as child support payments among the regions of Peru. Conclusion: Child support debts were characterized as coming mostly from employed males, and more cases of debtors were identified in the Peruvian highlands. © 2024 Sociedad espanola de dietetica.
