J-STAGE｜The Tohoku Journal of Experimental Medicine｜246 巻 (2018), 1 号The Japan Environment and Children’s Study (JECS) in Fukushima Prefecture: Pregnancy Outcome after the Great East Japan Earthquake

Japan Environment and Children’s Study (JECS) is nationwide birth cohort study that was initiated in January 2011 to investigate the effect of environmental factors on children’s health. Soon after the JECS started, the Great East Japan Earthquake occurred on March 11, 2011, with subsequent nuclear accident at the Fukushima Daiichi Nuclear Power Plant, causing catastrophic damage in Fukushima Prefecture. After the disaster, JECS was relaunched to cover all areas in Fukushima Prefecture due to public concern. In this study, we used the results of individuals enrolled in JECS, who gave birth during 2011-2014 in Fukushima Prefecture, to elucidate pregnancy outcomes in Fukushima Prefecture.
