Aims and objectives. The study aimed to determine bio-psycho-social risk factors for preterm birth in a sample of Turkish
women without chronic illnesses and evaluate their anxiety and depression in early postpartum period.
Background. Preterm birth is a devastating event with long-term health and social implications. Studies have identified several
risk factors; however, the contribution of these causes differs by ethnic groups.
Design. This case–control study was conducted in a tertiary hospital in Istanbul over one year. In total, 149 preterm mothers
were included in the case group and 150 term mothers who delivered in the same day with a case group woman were included in
the control group. Chronic illnesses and anomalies were excluded.
Method. Data were gathered using a form that addressed risk factors for preterm birth. Multidimensional Scale of Perceived
Social Support, Beck Depression Inventory and Spielberger’s State-Trait Anxiety Inventory were administered within 24–
72 hours after birth
