Abstract

Objective: Febrile seizure (FS) as the most common form of seizures in childhood, affects 2-5% of all children across the world. The present study reviews available reports on FS recurrence frequency and evaluates its associated risk factors in Iran. Methods: We searched the Persian database such as: SID, MagIran, Medlip, Irandoc, Iranmedex as well as English databases PubMed, ISI, and Scopus. Random effects models were used to calculate 95% confidence intervals. Meta regression was introduced to explore the heterogeneity between studies. Findings: The overall FS recurrence rate was 20.9% [95% confidence interval (CI): 12.3-29.5%]. The frequency of FS simple and complex types was 69.3% (95% CI: 59.5-79.0) and 25.3% (95% CI: 19.6-31.0), respectively. A positive familial history of 28.8% (95% CI: 19.3-38.4%) was observed for childhood FS including 36.2% (95% CI: 27.3-39.6%) for the simple and 29.4% (95% CI: 23.1-33.5%) for the complex type. The heterogeneity of recurrent FS was significantly affected by sample size (P=0.026). Conclusion: Almost one-third of FS children had a positive familial history. The increased risk of recurrence in patients with symptomatic seizures needs to be fully considered by parents, physicians, nurses and health policy makers.
