Outline of Final Research Achievements

With the growing importance of childhood mental health, overseas studies have suggested the impact of alcohol consumption during pregnancy on the mental health of the child. Overseas studies are mainly cases of fetal alcohol syndrome and high alcohol intake. Since drinking during pregnancy is not common in Japan, and there is little evidence even at low and moderate levels of alcohol consumption, we examined the effects of drinking during pregnancy on adolescent depression in Japan. Using data from a birth cohort, we selected target groups by propensity score and found that drinking during pregnancy was associated with 1.9 times greater risk of developing depressive symptoms in adolescence than not drinking at all.

Academic Significance and Societal Importance of the Research Achievements

妊娠時の飲酒は、出産するまでのみならず、出生後にも児に様々な影響があるというエビデンスが蓄積されている。例えば、米国小児学会では、たとえ少量でも妊娠時のアルコール摂取はやめるようにとガイドラインを出している。日本では、近年妊婦の飲酒率は減少傾向にあるが、母子保健活動において啓発活動をする際にも根拠のバリエーションは必要であり、本研究のような結果は役に立つと思われる。
