title: [Assessment of the role of some risk factors for preterm birth and benefit of screening implement].
abstract: The occurrence of preterm birth (PTB) is dependent on the effects and interaction of various risk factors. The purpose of this study was to determine the role of some of the multiple known risk factors for the onset of spontaneous PTB. Our results show that: the age (<18 and >40) and the weight of the pregnant woman (low weight or overweight), a history of miscarriages before 12 gestation week and mild anaemia (100-110 g/l) are not independent factors for PTB. A more significant dependence exists between PTB and a history of previous PTB, moderate and severe anaemia (Hb below 100 g/l); more than 50% cervical effacement and more than 2.5 cm cervical dilatetion, but their effect on PTB is less manifested compared to the impact of infection (particularly intraamniotic). Directed search for several risk factors in most cases detects pregnant women at high-risk for PTB and makes its prevention possible.
