Objective:
To determine whether assisted reproductive technology (ART) treatment adds obstetric and neonatal risks over and above that of underlying infertility-related diagnoses.
Design:
Retrospective study of linked ART, birth certificate, hospital discharge data, and outpatient insurance claims data in Massachusetts (2013-2017).
Setting:
Database.
Patient(S):
Singleton deliveries in women with and without diagnoses of tubal disease, polycystic ovarian syndrome (PCOS), other ovulatory conditions, or endometriosis, identified from the insurance claims and ART data.
Intervention(S):
None.
Main Outcome Measure(S):
ART and non-ART pregnancy and delivery outcomes were compared with each other and with women with no history of infertility or usage of fertility treatment (fertile group). Generalizing estimating equations with Poisson distribution and exchangeable correlation structure were used to obtain adjusted relative risk ratios (aRRs) and 95% confidence intervals (CIs).
Result(S):
Infertility-related diagnoses significantly increased the risks of pregnancy hypertension (PCOS: aRR, 1.13, 95% CI 1.00-1.27), preeclampsia/eclampsia (tubal: aRR 1.28, 95% CI 1.02-1.61; PCOS: aRR 1.23, 95% CI 1.06-1.43; other ovulatory: aRR 1.11, 95% CI 1.02-1.20), gestational diabetes (tubal: aRR 1.28, 95% CI 1.08-1.50; PCOS: aRR 1.58, 95% CI 1.42-1.75; other ovulatory: aRR 1.19, 95% CI 1.12-1.26), and placental problems (tubal aRR 1.47, 95% CI 1.11-1.94), as well as low birthweight and prematurity, compared with deliveries from the fertile group. Within each diagnosis, the use of ART consistently increased the risk of placental problems (aRR 1.49-2.86) but varied for other conditions.
Conclusion(S):
Our study demonstrated that compared with the fertile group, risk was elevated in pregnancies and deliveries from women with tubal, PCOS, other ovulatory, and endometriosis diagnoses who did/did not undergo ART treatment. Placental abnormalities were particularly elevated in ART compared to non-ART deliveries having the same diagnosis.
