A research group led by Professor Hiroshi Kurita of the Department of Dentistry and Oral Surgery, Shinshu University School of Medicine, Dr. Noriko Motoki of the Center for Perinatal, Pediatric, and Environmental Epidemiology, Shinshu University School of Medicine and Professor Tetsuo Nomiyama of the Department of Preventive Medicine and Public Health, Shinshu University School of Medicine investigated the association between maternal alcohol consumption during pregnancy and the occurrence of congenital malformations, based on data obtained from The Japan Environment and Children's Study, a national birth cohort survey led by the Ministry of the Environment.

The association between the occurrence of congenital malformations including congenital heart disease, external genitalia in boys, cleft lip and palate, limb dysplasia, brain malformations, and gastrointestinal atresia and the amount of alcohol consumed per week was analyzed in 73,595 singleton births nationwide. The study did not indicate an adverse association between drinking during pregnancy and the occurrence of the congenital malformations. However, it is necessary to take into account the fact that the subjects were moderate drinkers and that their reports of alcohol consumption were self-reported and not objective alcohol consumption data, and further research is needed.

The study was published in the November 2020 issue of the journal Pediatric Research. Please see the link below.
