Objective: The aim of this study was to compare perinatal, obstetric and newborn outcomes between women aged 20-29 years and 35 years or older and to estimate whether adverse outcome was related to maternal age. Materials and Methods: This is a retrospective study in women aged >35 years (109 women) and in a control group of women aged 20-29 years (100 women) who delivered during 2015 in the Vilnius City Clinical Hospital. Age was the main independent variable of interest. We calculated adjusted odds ratios of individual severe maternal and perinatal outcomes in these women. Statistical analysis was performed using the SPSS, version 23.0. Results: We enrolled 209 women, from whom 109 women were older than 35 years. The mean age in the study group at the time of delivery was 37,4±0,22 years and in the control group 25,35±0,23 years. In study group, 54,6% of women gave birth by cesarean section; in control group 21% (p<0,05). The average time of vaginal delivery in the study group was 567,08±28,08 min and 488,36±21,33 min (p<0,05) in the control group. No statistically significant difference was observed in both groups between other outcomes - pregnancy- related illnesses (anemia, gestational diabetes, arterial hypertension), infant condition (Apgar rating, cord blood pH value), congenital malformations, early neonatal morbidity (hypotrophy, congenital infection and glucose metabolism disorders) (p>0,05). Conclusion: Vaginal birth among women older then 35 years lasted statistically significantly longer than women of optimal age. Older women were 2,6 times more likely to give birth by cesarean section than younger woman. No signifficant difference in all other outcomes - pregnancy-related illnesses, infant‘s postnatal condition, congenital malformations, incidence of early neonatal morbidity was observed between both groups. |
