Delivery before 37th week of gestation is defined as preterm, independently of body mass of babies, according to the World Health Organization. Premature birth is the current problem in the world due to the high risk of neonatal morbidity and mortality and incompletely clear etiology. In our country the frequency of preterm delivery is 6%. We have retrospectively analyzed early deliveries in Health Center Kosovska Mitrovica in the period from 2009 to 2013. In this five-year period, there were totaly 3398 deliveries, of which 148 or 4.35 % were preterm delivery. The aim of this study was to investigate the incidence of premature birth in the five-year period in relation to: the total number of births in a given period, the age of the patients, the manner of completion of delivery, gestational week of pregnancy, parity and the most common causes that led to the PTP. In the analysis we have included the body weight and Apgar score of premature infants. We have used protocols of births, maternal history of disease, neonatal protocols and lists of newborns. Most of them were multiparas (41.2 %),56.7 % of pregnant women were aged of 21-30 years and pregnancy in 79.9 % of cases ended with 33 to 37 ng. Vaginal deliveries were completed in 84.4% of premature births, and caesarean in 15.6%. Twin pregnancies with preterm deliveries were represented in 10.2%. The most common weight of premature infants ranged from 2000 to 2500 grams (48.6 %). The most common causes that led to the PTP were PPROM (22.9 %), unknown causes (27. 1 %), multiple pregnancy (18.2 %), genital infection (8.7 %), cervical incompetence (6.7 %), IUGR (5.4%), PIH (4.2%), placental abruption and placenta previa (2.1 %) and other (4.7%) .
