Preterm birth is a major cause of significant increases in neonatal morbidity, mortality and long-term complications. It is now believed that preterm labor is initiated by several mechanisms, including infection or inflammation, uteroplacental ischemia or hemorrhage, uterine overdistension, stress, and other immunologically mediated processes. The causes of premature birth are varied and multifactorial: these include pregnancy-induced hypertension, premature rupture of membranes, placenta previa, placental abruption, maternal depressive symptoms, a history of previously mentioned preterm birth, pulmonary disease, heavy work during pregnancy, multiple pregnancies, urinary tract infections, stillbirths, history of miscarriages and much more. Identifying risk factors is a reasonable goal for many reasons, as it not only provides important information about the mechanisms leading to preterm birth, but also allows for the identification and targeting of women at risk. The use of alternative models of antenatal care, timely treatment of intrauterine infections, improved maternal nutrition and lifestyle modifications, and reduction of non-medical indications for induction of labor or cesarean section are common strategies used to reduce preterm birth.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>рrematurity, premature birth, antenatal risk factors.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>недоношенность, преждевременные роды, антенатальные факторы риска.</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
