The aim of the study was to evaluate the association between fetal stillbirth and advanced maternal age in the United States (US). This was a population-based study using the Natality and Fetal Death datasets for the years 2003-2017. We built Cox proportional regression models to examine the likelihood of stillbirth among women aged ?40 years. Out of a total of 57,273,305 births, stillbirth was observed in 302,522, yielding a stillbirth rate of 5 per 1000. After adjusting for confounders, women of advanced age (?40 years) had a 40-50% greater risk of stillbirth compared to women 20-29 years of age.

To estimate the risk of stillbirth following infertility treatment in the United States (US), we analyzed data from the US Natality and Fetal Death files from 2014 to 2017. We built Cox proportional regression models to generate adjusted hazard ratios (HR) for the risk of stillbirth among women who utilized various modalities of infertility treatment within the study period. Women who used any infertility treatment and, specifically, assisted reproductive technology (ART), had an elevated risk of stillbirth (HR: 1.21, 95% CI:1.09 -1.33) compared to women who did not use ART. We concluded that in this population, the risk of stillbirth was elevated among women using infertility treatment.
