OBJECTIVE: To study the role of iron deficiency as a risk factor for simple febrile seizures. DESIGN: Case control study. SETTING: Pediatric department of a tertiary care teaching hospital. PARTICIPANTS: 154 cases and 154 controls were included in the study. Consecutive cases and concurrent controls were selected. Cases were children of age group 6 months to 3 years presenting with simple febrile seizures. Controls were children of same age group presenting with short febrile illness but without any seizures. METHODS: After informed consent, detailed history was taken and clinical examination done in both cases and controls and blood investigations were done to diagnose iron-deficiency in both cases and controls. Iron deficiency was diagnosed as per WHO criteria (hemoglobin value <11 g%, red cell distribution width of >15% and serum ferritin value <12 ng/mL). Other explanatory variables, which can be the potential confounders were also included in the study and considered for analysis. RESULTS: Highly significant association was found between iron deficiency and simple febrile seizures in both univariate and multivariate analysis. Crude odds ratio was 5.34 (CI 3.27- 8.73, P<0.001) and adjusted odds ratio in the logistic regression analysis was 4.5 (CI 2.69- 7.53, P <0.001). CONCLUSIONS: Iron deficiency is a significant risk factor for simple febrile seizures in children of age group 6 months to 3 years.
