Infants with a very low birthweight (less than 1500 g) have a fundamental influence on perinatal mortality and mortality of babies up to one year also nowadays. The epidemiological role of different signs of risk in the context of the birth of these children is presented. The total mortality of the infants with a very low birthweight (less than 1500 g) was 64,4%. Usually there were combinations of factors, which caused the death of the infants. Complications of secundinae, immaturity and malformations were the substantial factors of lethality of the stillbirths. At the mortality of babies there were intracranial bleedings and immaturity (less than 1000 g, less than 28 completed weeks of pregnancy) in the foreground of the causes of death.
极低出生体重（低于1500克）的婴儿即使在如今对围产期死亡率以及一岁以内婴儿的死亡率仍有根本性影响。本文阐述了这些儿童出生背景下不同风险迹象的流行病学作用。极低出生体重（低于1500克）婴儿的总死亡率为64.4%。通常是多种因素共同作用导致婴儿死亡。胎盘胎膜残留并发症、未成熟和畸形是死产致死的主要因素。在婴儿死亡原因中，颅内出血和未成熟（体重低于1000克、妊娠不足28足周）最为突出。
