Objective: Our study was performed to analyze the interrelationship between breastfeeding for the first 6 months of life and the incidence of febrile seizures (FS). Study Design: A case-control study was conducted in Renmin Hospital of Wuhan University. Three hundred thirty-six patients diagnosed with FS were enrolled as the case group, and 336 febrile children with matched age and gender were enrolled as the control group. Clinical information of all cases was collected from the Electronic Medical Record, including feeding patterns. The primary outcome was the difference of feeding modes between cases and controls, while the secondary outcome included the difference of feeding patterns between simple FS (SFS) and complex FS (CFS). Results: The 336 patients with FS comprised 294 with SFS and 42 with CFS. The difference in feeding methods between the case group and the control group was statistically significant, and children who were breastfed exclusively had a lower risk of suffering from FS compared with formula feeding (odds ratio [OR], 0.504 and 95% confidence interval [CI], 0.303-0.841); although partial breastfeeding exhibited a slight protective effect against FS, the protective role was not statistically significant (OR, 1.016 and 95% CI, 0.560-1.846). In addition, our dates showed that feeding mode was not a risk factor in the occurrence of SFS or CFS (p > 0.05). Conclusion: Our data confirm that exclusive breastfeeding is an independent protective factor that can reduce the occurrence of FS.
