However, it is not known how this affected the seasonal changes of pregnancy and childbirth. Therefore, this study investigated the impact of the GEJE in the Fukushima Prefecture on spontaneous and induced abortions with regard to seasonal variability.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We used the data of vital statistics of live birth and stillbirth registry and the census survey of the Fukushima Maternity Care Facility. We calculated the spontaneous and induced abortion rate for 2011\u20132016 using two different methods (cross\u2010sectional and longitudinal). We calculated the quartiles and outliers to determine the impact and duration of the GEJE. Periodicity was investigated using spectral density analysis. The data were analyzed for the entire Fukushima Prefecture and by region.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The spontaneous abortion rate did not show specific changes after the GEJE. Contrarily, the monthly analysis in the cross\u2010sectional method, revealed specific increases in induced abortion rate during the year after the GEJE; in the longitudinal method, induced abortions increased among women who became pregnant within 1 year after the GEJE. Spontaneous abortion showed no specific periodicity, while induced abortion showed cycles of 6 and 12\u2009months, with a particular increase in May each year.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The spontaneous abortion rate was not affected by the GEJE. The changes in the induced abortion rate after the disaster may have overlapped with the timing of the increased periodicity, and cannot be attributed solely to the GEJE.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jog.15529","type":"journal-article","created":{"date-parts":[[2023,1,3]],"date-time":"2023-01-03T00:35:05Z","timestamp":1672706105000},"page":"812-827","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Impact of the Great East Japan Earthquake on spontaneous abortion and induced abortion: A population\u2010based cross\u2010sectional and longitudinal study in the Fukushima Prefecture based on the census survey of the Fukushima maternity care facility and vital statistics"],"prefix":"10.1111","volume":"49","author":[{"given":"Yuta","family":"Inoue","sequence":"first","affiliation":[{"name":"Department of Medical Treatment Recover Care Nursing, Graduate School of Biomedical Sciences Tokushima University  Tokushima Japan"},{"name":"Division of Environmental Medicine and Population Sciences Graduate School of Medicine Osaka University  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuko","family":"Ohno","sequence":"additional","affiliation":[{"name":"Graduate School of Medicine, Division of Health Sciences Osaka University  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomotaka","family":"Sobue","sequence":"additional","affiliation":[{"name":"Division of Environmental Medicine and Population Sciences Graduate School of Medicine Osaka University  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takako","family":"Fujimaki","sequence":"additional","affiliation":[{"name":"Division of Environmental Medicine and Population Sciences Graduate School of Medicine Osaka University  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ling","family":"Zha","sequence":"additional","affiliation":[{"name":"Division of Environmental Medicine and Population Sciences Graduate School of Medicine Osaka University  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuhisa","family":"Nomura","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology School of Medicine Fukushima Medical University  Fukushima Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7782-3396","authenticated-orcid":false,"given":"Hyo","family":"Kyozuka","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology School of Medicine Fukushima Medical University  Fukushima Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shun","family":"Yasuda","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology School of Medicine Fukushima Medical University  Fukushima Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akiko","family":"Yamaguchi","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology School of Medicine Fukushima Medical University  Fukushima Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2224-4455","authenticated-orcid":false,"given":"Kentaro","family":"Kurasawa","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Yokohama City University Medical Center  Yokohama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8618-4063","authenticated-orcid":false,"given":"Keiya","family":"Fujimori","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology School of Medicine Fukushima Medical University  Fukushima Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,1,2]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/OGX.0b013e31820eddbe"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/msj.20032"},{"key":"e_1_2_9_4_1","first-page":"350","article-title":"Increased leukemia, lymphoma, and spontaneous abortion in Western New York following a flood disaster","volume":"96","author":"Janerich DT","year":"1981","journal-title":"Public Health Rep"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1017\/dmp.2015.69"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.3109\/14767058.2012.678437"},{"key":"e_1_2_9_7_1","unstructured":"Nuclear Regulation Authority.(JCN 9000012110002) results of airborne monitoring by the Ministry of Education Culture Sports Science and Technology and the U.S. Department of Energy.
