Background:

Preterm delivery is a significant concern in maternal and infant health.
Identifying epidemiological risk factors is essential for developing targeted prevention strategies.

Purpose of the Study:

To investigate the epidemiological factors associated with preterm delivery.
To identify significant risk factors for preterm birth in a specific population.

Main Methods:

A case-control study was conducted at Yale-New Haven Hospital.
The study included 175 mothers of preterm infants and 313 mothers of term infants.

Main Results:

Low socioeconomic status, low pregravid weight, and inadequate weight gain were significant risk factors.
Previous preterm delivery, infertility, induced abortion, vaginal bleeding, and placental issues were also associated with preterm birth.
Lack of physical activity, early alcohol consumption, and negative pregnancy attitudes were identified as risk factors.

Conclusions:

Multiple socioeconomic, medical, and behavioral factors contribute to preterm delivery risk.
These findings can inform clinical practice and public health interventions aimed at reducing preterm birth rates.
