Complications among assisted reproductive technique (ART) twin gestations versus spontaneously conceived twin gestations (SC): A retrospective outcome analysis among an Afro-Caribbean population at a university-based hospital in Jamaica

Abstract

Aim: The aim of the study is to compare the frequency of maternal and neonatal complications among pregnant women with twin pregnancies conceived spontaneously versus conceived by assisted reproductive technique (ART). Methods: Univariate and bivariate analyses of maternal characteristics and neonatal outcomes were performed in this retrospective cohort study at a university-based hospital between 2006 and 2016 in Jamaica, a middle-income Caribbean country. Neonatal data were the primary outcomes: APGAR scores, gestational age, birth weight, admission to the neonatal intensive care unit (NICU), and the level of ventilatory support required. Maternal characteristics, comorbidities, and pregnancy complications were other outcomes studied. Results: There were 157 SC and 27 ART twin gestations. Women conceiving via ART were more likely to be advanced maternal age (p greater 0.001), have uterine fibroids (p greater 0.001), previous myomectomy (p=0.001), and incompetent cervix (p=0.003), delivery by cesarean section (p=0.007), and experience hemorrhage (p=0.017) than SC. There were no statistically significant differences in rates of preterm births, birth weight, APGAR scores, or NICU admissions. Assisted reproductive technique twins were more likely to require continuous positive airway pressure (CPAP) (p=0.025), with no differences observed between the two groups for neonatal respiratory distress. Conclusion: In our predominantly Afro-Caribbean population, ART mothers were observed to have more poor maternal outcomes than mothers who conceived spontaneously. Assisted reproductive technique and SC twins had similar neonatal outcomes; however, ART twins were more likely to require CPAP.
