ObjectiveThe Great East Japan Earthquake and Fukushima Daiichi nuclear disaster occurred on 11 March 2011. We investigated the incidence of SGA (small for gestational age) in the Fukushima Prefecture in newborns delivered by women who were pregnant at the time of the disasters and identified any risk factors for SGA.MethodsSubjects were women who were pregnant at the time of the disasters. Questionnaires were sent to the women who lived in the Hamadori area (seaside and near to the nuclear power plant) at the time of the disasters as well as to a control group of women who lived outside the Hamadori area. The incidence of SGA was compared. Logistic regression analysis was performed to identify the risk factors for SGA.ResultsIn total, 325(5.6%) women had infants with SGA. Neither area nor the trimester of pregnancy at the time of the disasters influenced the incidence of SGA. Pregnancy-induced hypertension (PIH) was higher in the SGA group. PIH was found to be an independent risk factor for SGA.ConclusionWe found no evidence that the Great East Japan Earthquake and the Fukushima Daiichi nuclear disaster increased the incidence of SGA in the Fukushima Prefecture.
