This study, part of the ongoing, nationwide Japan Environment and Children’s Study on environmental factors and children’s health and well-being, examined the relationship between intimate partner verbal abuse during pregnancy and newborn hearing screening (NHS) referral, which indicates immature or impaired auditory function. Komori et al. found that, among nearly 80,000 mother-infant pairs, NHS referrals were highly associated with verbal abuse during pregnancy, indicating that such abuse should be avoided to preserve the auditory function of newborn children.
