Backgound: Epilepsy is the most common chronic neurological disease seen in Pediatrics Neurology Units in developing countries negatively affecting school attendance and academic performance.Comorbid learning and behavioral problems may also contribute to the academic difficulties among children with epilepsy. The main aim of this study is to assess the extent and factors contributing school absenteeism among school-aged children and adolescents with epilepsy.Methods: A hospital based follow-up study was conducted among school-aged children and adolescents with epilepsy between the ages of 7-18 years attending an outpatient Pediatric Neurology Clinic. A sample of 183 children and adolescents were included in the study. The participants (children and their parents/caregivers) gave information concerning the socio-demographic characteristics of the child and the primary caregiver, information regarding the child's presentation and whether or not they disclosed to teachers and peer. Medical charts were thoroughly reviewed on the diagnosis and prognosis. Study participants characteristics were described and logistic regression was used to determine factors associating with school absenteeism.Results: School absenteeism (≥1 days/month) over six month period among children aged 7-18 years with epilepsy was 69.4%. Factors which correlated with school absenteeism included female sex (AOR 2.19, 95% CI 1.03-4.84), children with known causes for seizures AOR 2.51, 95% CI 1.09-5.86), having seizure at school and longer epilepsy duration.Conclusion recommendation: School absenteeism was found in over two thirds of children aged 7-18 years with epilepsy attending an outpatient epilepsy clinic in Ethiopia.
