Kyozuka H, Murata T, Fukusda T, et al. - This study was undertaken to investigate the impact of maternal age on the incidence of placental abruption. Researchers applied data of singleton pregnancies from the Japan Environment and Children’s Study, which was a prospective birth cohort study conducted between January 2011 and March 2014 across 15 regional centers in Japan. They used a multiple regression model to distinguish if maternal age (< 20 years, 20–24 years, 25–29 years, 30–34 years, and ≥ 35 years) is a risk factor for placental abruption. They enrolled a total of 94,410 Japanese women (93,994 without placental abruption and 416 with placental abruption). The results demonstrate that besides advanced maternal age, teenage pregnancy was correlated with placental abruption. Currently, in Japan, the mean maternal age has been changing. Thus, it is necessary for obstetric care providers to provide proper counseling to young women based on up-to-date evidence.
