[CHANGING OF STILLBIRTH RISKS IN DIFFERENT OPTIONS OF ITS REGISTRATION].

Purpose of the study - comparing of stillbirth rates and some of its risk factors in different options (after 22 and 28 completed weeks of gestation) of its registration. This study was conducted on the basis of a regional prenatal centre. Monitoring was conducted retrospectively with continuous coverage of all cases of completed pregnancy after 22 completed weeks of gestation. Stillbirth coefficient was calculated based on body weight (500 grams or more - I option, and a 1000 grams - II option) based on 100 of all birth cases (corresponding to 500 grams body weight or more, and 1,000 grams or more). According to data of Lenkoran Prenatal Centre 5,42‰ (95% confidence interval: 5,02-5,82) of born with body mass 500 grams and more (22 and more completed gestation weeks) are stillborns. Stillbirth factors are mother's age (25 years and more), the first, third and more birth, excess body weight of the mother, maternal hypertension and diabetes. Planned transfer to registration of alive birth cases after 22 completed weeks of gestation (weight 500 grams or more) will be associated with multiple growth of officially registered cases of stillbirth. Preventing the risk of growth of stillbirth may be gained by prenatal obstetric care.
