[Informativeness and relative risk of factors leading to spontaneous abortion]

Results of epidemiological evaluation of different risk factors underlying spontaneous abortion are discussed. Based on the mathematical analysis of examination findings in women in the course of pregnancy and at its termination (at term and preterm), major risk factors and abnormality patterns were established in all followed-up pregnancies as well as in the nonparous group. The informative value and the degree of risk of factors and conditions affecting preterm pregnancy termination are delineated.
