ABSTRACT: OBJECTIVE:To explore conditions and outcomes of a first delivery at term that might predict later preterm birth. DESIGN:Population based, prospective register based study. SETTING:Medical Birth Registry of Norway, 1999-2015. PARTICIPANTS:302 192 women giving birth (live or stillbirth) to a second singleton child between 1999 and 2015.
