The required information was gathered by interviewing patients and review records and finally the results were drawn using statistical methods. Between history of preterm delivery, diabetes, infectious diseases, dental disease, anemia and urinary tract infection and preterm delivery, a significant relationship was found. Between age, occupation, body mass index, housing status, mother's underlying disease, preoclampsia and the time in medicine and preterm delivery, there was no significant relationship.
