Objective: To identify the association between individual and socioeconomic factors during the first thousand days of the child's life and the occurrence of risk behaviors for the development of malocclusions. Material and Methods: Cross-sectional study. A sample of 655 6-year-old schoolchildren and families was included. Interviews with mothers were performed at home. The dependent variables were risk behaviors to the development of malocclusions. Independent variables were socioeconomic conditions, aspects of gestation, birth and health of the child up to two years of age. Bivariate and multivariate analyzes were performed through Poisson regression. Results: Maternal education of less than eight years was independently associated with the interruption of exclusive breastfeeding until the fourth month (PR=1.58 CI 95%; 1.07; 2.37). Occupation of the mother with income [PR=1.26; 1.02; 1.56)], occupation of the father without income [PR=1.46 (1.01; 2.14)] were associated fwith interruption of breastfeeding until the sixth month. Pregnancy in adolescence [PR=0.83 (0.70; 0.98)] and nursery attendance [PR=1.15 (1.02; 1.28)] were associated with bottle use. Nursery attendance [PR=1.27 (1.01; 1.59)], hospitalization in the first 29 days of life [PR=1.34 (1.01; 1.80)], occurrence of reflux [PR=1.30 (1.01; 1.70)] were associated with pacifier using. Conclusion: Variables related to the period of the first thousand days of life are associated with higher risk behaviors for the occurrence of malocclusions.
