Filter by:Maternal age is an important factor affecting the pregnancy process and its results. Adverse obstetric outcomes such as preterm birth, stillbirth, and infant mortality are more common in women older than 35 years and younger than 20 years compared to women aged 20-29. Adolescent pregnancies have been associated with an increased risk of adverse pregnancy outcomes such as preterm birth, low birth weight, perinatal death, and maternal mortality. Advanced maternal age pregnancies were associated with higher rates of maternal hypertension and diabetes, and progressively worsening perinatal outcomes such as stillbirth, preterm birth, and low birth weight. Although the investigators' region has high birth rates, as far as they have observed, the rates of early and advanced maternal age are also quite high. the investigators' aim in this study is to determine the absolute effects of early and advanced maternal age on pregnancy and to investigate the pregnancy outcomes of these mothers.
