Description
Yasuaki Saijo and others study weight before birth and low mood after birth in Japan in a 2026 birth cohort paper that tracked women forward in time. Both low weight and excess weight have been tied to low mood after birth, while young Japanese women often wish to stay slim, so the local pattern merited a close look.
The Japan Environment and Children's Study tracked 91,640 women who were expecting. It tested weight groups against later low mood and asked whether birth by surgery, low birth weight, birth defects, or breast feeding carried part of the link. The paper helps doctors counsel women on weight and mood risks around birth with local facts, not guesswork.
