Childhood tuberculosis (c-TB) continues to be one of the causes of morbidity and mortality in children, but there is still little information on the delay in the initiation of specific treatment. To determine the risk factors associated with delayed initiation of tuberculosis (TB) treatment in children under 15 years of age. Case-control study. Patients <15 years of age with a diagnosis of childhood pulmonary tuberculosis (c-PTB) with delayed treatment initiation >24 hours were included. Clinical and epidemiological variables were evaluated: age, gender, guardian's education, poverty level, origin, family history of TB, altered imaging findings, symptomatic, PPD >10mm, histology, bacteriology, resistance to treatment, and healthcare network. Bi and multivariate logistic regression analysis was performed, through which odds ratios were calculated. We evaluated 116 patients with c-PTB with a delayed initiation of specific treatment of more than 24 hours, and 264 with start of treatment in the first 24 hours. The delay in anti-tuberculosis treatment had a median of 3 days with an interquartile range of 2 to 7 days. The patient with the least educated guardian had a delay in treatment initiation with an odds ratio of 7.47 (95%CI: 4.13 - 13.52). Belonging to the healthcare network A of Callao decreased the probability of having tuberculosis by 0.224 times (95%CI:0.11 - 0.46). Incomplete education level of the guardian is a risk factor associated with delayed initiation of c-PTB treatment in children under 15 years of age while belonging to the Callao healthcare network A is a factor that decreases the risk in the group under study.
