Febrile convulsions in a Serbian region: a 10-year epidemiological study

The first population-based study in the central region of the Republic of Serbia (total population 283,103) was carried out to assess some epidemiological features of febrile convulsions among children of between 6 months and 5 years of age. During the 10-year period, 1986 to 1995, there were 570 cases of the first febrile convulsions (287 males and 283 females). The average annual incidence rate was 3/1000 (2.9/1000 in males and 3.0/1000 in females), with the highest in 1995. During the study period, a significantly increased linear regression trend was observed. During the follow-up period of 5 years for children who had their first febrile convulsions in 1989 and 1990 (total 154 cases), 27 (17.5%) had a recurrence of the disorder, and ten (6.5%) had one or more afebrile seizures, of whom seven children (4.5% of total sample) developed epilepsy (recurrent afebrile seizures).
