Characteristics and adverse outcomes of Chinese adolescent pregnancies between 2012 and 2019

Abstract We aimed to describe the characteristics of adolescent pregnancy, determine its effect on adverse maternal and perinatal outcomes and explore whether that association varies with gestational age with the goal of proposing specific recommendations for adolescent health in China. This study i...
