Non-reassuring foetal status and sleep problems in 1-year-old infants in the Japan Environment and Children’s Study: a cohort study

Abstract Abnormal autonomic function may cause false-positive non-reassuring foetal status (fpNRFS) and may also cause sleeping problems after birth. However, an association between fpNRFS and sleeping problems in infants has not been reported. We previously showed an association of NRFS with temper...
