The purpose of this study was to analyze association between maternal age and outcome of pregnancy in primipara.
We evaluated retrospectively the clinical characteristics and pregnancy outcomes in primiparous mothers who delivered a fetus after more than 22 weeks of gestation in I hospital from January 2017 to December 2018. This research was analysed 54 mothers aged 40 years and above, 226 mothers aged 35-39 years, 341mothers aged 30-34 years and 223 mothers aged 29 years and below were included.
The statistical analysis was performed using Chi-square tests and Multivariable logistic regression.
There was significantly higher incidence of level of education, occupation, abortion history, assisted
reproductive technology and multiple pregnancy all showed significant results, depending on maternal age. (p<.000)
There was significantly higher incidence of maternal complications (p=.004), gestational diabetes mellitus (p<.000), preeclampsia (p=.031), cesarean section (p<.000), premature delivery (p=.014), low birth weight neonatal (p=.045) and neonatal intensive care unit admission (p=.031) showed significant results, depending on maternal age.
The odds ratio in maternal complications was 2.327 higher in mothers 40 years and above than mothers 29 years and below, 1.912 higher in mothers 35-39 years than mothers 29 years and below. The odds ratio in gestational diabetes mellitus was 3.337 higher in mothers 40 years and above than mothers 29 years and below, 2.698 higher in mothers 35-39 years than mothers 29 years and below. The odds ratio in preeclampsia was 1.704 higher in mothers with a occupation than mothers without a occupation. The odds ratio in premature delivery was 1.704 higher in mothers with a occupation than mothers without a occupation.
Consequently, significant association between maternal age and outcome of pregnancy in primipara. However, as the maternal age increases, socioeconomic status and improved materal health levels are expected to have a greater impact on outcome of pregnancy despite the physical defects of biological aging.
