Abstract
The purpose of this study was to evaluate the maternal outcome in women with very advanced maternal age (VAMA) at childbirth (>45 years) compared to advanced maternal age (35-39 and 40-44 years). Retrospective cohort study using the Texas Public Use Data File, years 2013-2014. Maternal age was a three-level variable: 35-39 (referent), 40-44, and 45-59 years (VAMA). Adjusted risk ratios (aRRs) for the two older age groups for various obstetrical and nonobstetrical complications were calculated from log-binomial regression models. The sample consisted of 96,879 deliveries. In univariate analyses, a higher frequency (p < 0.05) of gestational diabetes, pregestational diabetes, chronic hypertension, pregnancy related hypertensive disorders, multiple gestation, oligohydramnios, polyhydramnios, placenta previa, postpartum hemorrhage, small for gestational age, intrauterine fetal death, and length of stay were noted in the two older maternal age groups compared to the youngest maternal age group. Multiple gestations were noted to be more frequent in the two older groups: the VAMA group had a 336% increase in their risk (aRR = 4.36, 95% CI: 3.68-5.17), while women 40-44 years of age experienced a 17% increase in their risk (aRR = 1.17, ...Continue Reading
