Preterm labour is the main reason of fetal and neonatal deaths. The pathology and etiology of preterm labour are still unknown. The aim of this study was to estimate the demographic and socioeconomic risk factors of premature labour. The study was carried out on 158 pregnant women with preterm labour and rupture of membranes and 120 women with preterm without ruptured membranes. This study determine that age (both young and advanced), low education level, and absent or late prenatal medical care have association with the risk of preterm delivery.
