ABSTRACT
OBJECTIVES:
To investigate the impact of maternal age on pregnancy outcomes with special emphasis on adolescents and older mothers and to investigate the differences in demographic profile between adolescents and older mothers.METHODS:
This study is a secondary analysis of pregnancy outcomes of women in Riyadh Mother and Baby cohort study according to maternal age. The study population was grouped according to maternal age into five subgroups; <20, 20-29, 30-34, 35-39 and 40+years. The age group 20-29 years was considered as a reference group. Investigation of maternal age impact on maternal and neonatal outcomes was conducted with adjustment of confounders using regression models.RESULTS:
All mothers were married when conceived with the index pregnancy. Young mothers were less likely to be illiterate, more likely to achieve higher education and be employed compared with mothers ≥ 40 years. Compared with the reference group, adolescents were more likely to have vaginal delivery (and least likely to deliver by caesarean section (CS); OR=0.6, 95% CI 0.4 to 0.9, while women ≥40 years, were more likely to deliver by CS; OR 2.9, 95% CI 2.3 to 3.7. Maternal age was a risk factor for gestational diabetes in women ≥40 years; OR 1.7, 95% CI 1.3 to 2.1. Adolescents had increased risk of preterm delivery; OR 1.5, 95% CI 1.1 to 2.1 and women ≥40 years had similar risk; OR, 1.3, 95% CI 1.1 to 1.6.CONCLUSION:
Adverse pregnancy outcomes show a continuum with the advancement of maternal age. Adolescents mother are more likely to have vaginal delivery; however, they are at increased risk of preterm delivery. Advanced maternal age is associated with increased risk of preterm delivery, gestational diabetes and CS.Palavras-chave
