The aim of this work was to investigate the influence of advanced maternal age on the frequency of perinatal complications and complications in childbirth and to compare the obtained results with the frequency of the same in women who gave birth between the ages of 25 and 35. The research was conducted on 843 expectant women who gave birth in the Clinic for Women's Diseases and Childbirth of KBC Split in the period from January 1 to April 1, 2022. The results of the work include: the age of the expectant woman, fertility, pregnancy due date, mode of delivery, obstetric operations, pregnancy pathology (hypertensive disorders, gestational diabetes mellitus, placenta previa, placental abruption), newborn maturity and Apgar score. The research proved a higher frequency of perinatal complications in women of advanced age who gave birth compared to women who gave birth between the ages of 25 and 35. Pregnancy and childbirth at an older age had no influence on the low Apgar score of newborns, but newborns of such mothers were more often hypotrophic and hypertrophic. A higher percentage of the pregnancies of older mothers were terminated by caesarean section. The research results partly coincide with the research results from the world literature. The difference in results may exist due to different definitions of older age and different socio-demographic factors.
