Abstract

Background and Purpose Febrile seizures (FS) are the most common type of seizure during childhood, reportedly occurring in 2–5% of children aged 6 months to 5 years. However, there are no national data on the prevalence of FS in Korea. This study determined the prevalence, incidence, and recurrence rates of FS in Korean children using national registry data. Methods The data were collected from the Korea National Health Insurance Review and Assessment Service for 2009–2013. Patients with febrile convulsion as their main diagnosis were enrolled. The overall prevalence of FS in more than 2 million children younger than 5 years was estimated, and the incidence and recurrence rates of FS were determined for children born in 2009. Results The average prevalence of FS in children younger than 5 years based on hospital visit rates in Korea was 6.92% (7.67% for boys and 6.12% for girls). The prevalence peaked in the second to third years of life, at 27.51%. The incidence of FS in children younger than 5 years (mean 4.5 years) was 5.49% (5.89% for boys and 5.06% for girls). The risk of first FS was highest in the second year of life. The overall recurrence rate was 13.04% (13.81% for boys and 12.09% for girls), and a third episode of FS occurred in 3.35%. Conclusions Our study determined the overall prevalence of FS using data for the total population in Korea. The prevalence was comparable to that reported for other countries. Patients with three episodes of FS need to be monitored carefully.
