Objective: To analyze child safety seat usage errors among children enrolled at daycare.
Methods: This was a cross-sectional, observational study with prospective data collection and a retrospective analytical axis.
Results: Overall, 42.7% of the children studied were in incorrectly used seats. A logistic regression model showed that the likelihood of usage errors was higher if there were two or more children in the vehicle (odds ratio = 5.10, p = 0.007) and was dependent on parents' educational level and income (medium income and educational level: odds ratio = 7.00, p = 0.003; low income and educational level: odds ratio = 3.40, p = 0.03).
Conclusion: The results of this study are in line with findings reported in international publications.
