The purpose of this study was to examine the relationship between early childhood exposure to tobacco smoke and the risk of obesity and overweight in Japan. This study utilized a nationwide, population\u2010based longitudinal survey. The participants were restricted to 32\u2009081 children who had available information on maternal smoking history as well as childhood height and weight. We conducted a binomial log\u2013linear regression analysis with children of non\u2010smoking mothers as the reference group. The children with mothers who were smokers had a higher risk of developing obesity or being overweight compared to the children with mothers who were nonsmokers. The risk ratios were 1.20 (95% confidence interval [CI]: 1.09\u20131.32) for overweight and 1.17 (95% CI: 0.95\u20131.44) for obesity. Early exposure to maternal smoking increases the risk of being overweight and having obesity during childhood. The increased risk is more pronounced among children with mothers, smoked heavily, or parents, who were smokers.<\/jats:p>","DOI":"10.1111\/cob.12572","type":"journal-article","created":{"date-parts":[[2022,12,12]],"date-time":"2022-12-12T09:54:30Z","timestamp":1670838870000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Early childhood exposure to maternal smoking and obesity: A nationwide longitudinal survey in Japan"],"prefix":"10.1111","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4823-6325","authenticated-orcid":false,"given":"Miho","family":"Yamashita","sequence":"first","affiliation":[{"name":"Department of Foods and Human Nutrition Faculty of Human Life Sciences Notre Dame Seishin University  Okayama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Yorifuji","sequence":"additional","affiliation":[{"name":"Department of Epidemiology Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences  Okayama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naomi","family":"Matsumoto","sequence":"additional","affiliation":[{"name":"Department of Epidemiology Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences  Okayama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshihide","family":"Kubo","sequence":"additional","affiliation":[{"name":"Department of Pediatrics National Hospital Organization, Okayama Medical Center  Okayama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hirokazu","family":"Tsukahara","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University  Okayama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,12,12]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2010-3041"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/srep24987"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2458-13-1058"},{"key":"e_1_2_8_5_1","first-page":"44","article-title":"The effect of second\u2010hand smoke exposure during pregnancy on the newborn weight in Malaysia","volume":"21","author":"Norsa'adah B","year":"2014","journal-title":"Malays J Med Sci"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.2188\/jea.JE2007415"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pedneo.2013.05.005"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2018.11.194"},{"key":"e_1_2_8_9_1","first-page":"1125","article-title":"Risk factors for preterm birth, low birth weight and small for gestational age: a prospective cohort study","volume":"40","author":"Shen ZZ","year":"2019","journal-title":"Zhonghua Liu Xing Bing Xue Za Zhi"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1080\/19338244.2016.1255582"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.envint.2019.01.036"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(10)61388-8"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1093\/ntr\/ntv128"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.18332\/tid\/117958"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.11124\/JBISRIR-2017-003558"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/ppe.12001"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2047-6310.2012.00146.x"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0109184"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/dyu150"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1089\/chi.2015.0083"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0110974"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(17)32129-3"},{"key":"e_1_2_8_23_1","doi-asserted-by":"publisher","DOI":"10.1210\/jc.86.1.267"},{"key":"e_1_2_8_24_1","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2007-1618"},{"key":"e_1_2_8_25_1","doi-asserted-by":"publisher","DOI":"10.1038\/oby.2007.190"},{"key":"e_1_2_8_26_1","unstructured":"Longitudinal survey of children born in the 21st century (children born in 2010).
