background: - seizure is a transient occurrence of signs and symptoms resulting from abnormalrnexcessive neuronal activity in the brain. It is an important cause for hospital admissions in childrenrnfrom developing countries. it accounts for about 1% of all emergency department visits, and aboutrn2% of visits to children's hospital emergency department visits. It is a major factor for neurologicalrnand cognitive impairment in children living in sub-saharan africa. Limited studies have beenrnconducted in ethiopia relating to the prevalence and associative factors of seizures in children. rnObjective: - This study aims to assess the magnitude of seizure and itsâ€™ associated factors among 1rnmonth -12 years of age children admitted in tikur anbessa specialized hospital(tash), at the pediatricrnemergency unit from december 2016- december 2019. rnResult: - Medical records review was done for 256 children with a 96% response rate. Thernprevalence of seizure was 4.52 %( 45/1000 people) . 155( 60.5%) were males and with a male tornfemale ratio of (1.5:1). the mean age of patients was 3.7 years (with standard devation 2.8). Thernmean age for onset of a seizure in males and females was 1.3(sd 1.1-1.5 at 95% ci) and 2.0(sd1.6-2.5rnat 95% ci) respectively. on logistic regression, fever (or 1.85,p=0.01), newborn distress (orrn2.31,p=0.01), hypoxia brain injury (or 2.43,p=0.00), and home delivery (or 2.8,0.04) were found tornbe significant predictors seizure.head trauma was 1.3 times more likely to had an earlier onset of thernpediatric seizure, (aor: 1.3,p=0.00) , birth asphyxia, (aor: 2.3,p=0.00) hypoxic brain ischemia, (aor,rn2.2,p=0.02)developmental delay, (aor, 2.5,p=0.01),fever, (aor, 1.2,p=0.01),male (aor, 2.7,p=0.01)rnwere significantly associated with pediatric seizure early onset at p
