Introduction. Domestic burns are the leading accidental cause of morbidity and mortality worldwide, and the third leading cause of death in children. The lack of knowledge in preventive strategies against domestic burns is a health problem. Objective. To identify the association between sociodemographic characteristics and family composition with the knowledge, attitudes, and practices of parents regarding the prevention of burns in school children under 5 years of age at home in low-income communities in Bogotá C.D in 2023. Materials and Methods. Quantitative cross-sectional study. Surveys were conducted to parents of educational institutions. The information was organized in a database and statistical tests were applied for analysis and their respective associations. Results. 103 participants: 81 from institution #1 and 22 from institution #2. Higher percentage of women between 26–45 years old, low socioeconomic status, complete level of education, two-parent family nucleus. Greater frequency of appropriate knowledge at a complete level of education in fathers and mothers. Discussion. The low participation and little interest of parents on this subject in this study is striking. A similar finding already mentioned in the literature was the lack of preventive practices in the parents. In the male gender, there is a preference only to leave the children in the company of an adult, indicating the need to promote other practices such as maintenance of the infrastructure of the homes. The fireworks prohibition law presented greater approval from 33 years of age, a finding that has not been previously mentioned in the literature. Conclusion. The acquisition of knowledge, attitudes, and practices on the prevention of domestic burns in childhood can be influenced by sociodemographic characteristics of the parents, mainly age and educational level.
