Abstract
Risk factors for predicting recurrences of febrile seizures were studied in an unselected series of 169 children after their first febrile seizure. Follow-up data covering 2.1-6.8 (mean 3.8) years from the first febrile seizure were available from 167 of them (98.8%) including 72 girls. Altogether 35/167 (21.0%, 95% confidence intervals (CI) 14.6% to 29.1%) had further febrile seizures, and multivariate logistic regression analysis showed the number of febrile episodes (p = 0.011) and the occurrence of such seizures among first degree relatives (p = 0.015, relative risk 3.75, CI 1.22 to 11.5) to be significant risk factors for recurrences. Our findings indicate that more emphasis should be placed on preventing febrile episodes rather than concentrating only on preventing seizures with antiepileptic therapy.
