background: Previous studies have noted that as maternal age increases, the risk of fetal mortality increases; however, variations by race have not been well-defined.  This study examines the association between maternal age and fetal death, considering racial disparities.  Our hypothesis states that not only will the risk of fetal death increase with advancing age but also the disparities between racial groups will widen as age increases.

 

methods: Using 2007-2012 NCHS data for singleton fetal deaths (late: 28+ weeks) and live births among non-Hispanic white (NHW) and black (NHB), we calculated fetal mortality rates (per 1000 deliveries) by age categories (<20; 20-29; 30-39; 40+) and multivariable logistic regression, controlling for maternal risk factors.  Odds ratios (ORs) and ratios of odds ratios (RORs) and 95% confidence intervals (CI) were used to examine changes across maternal age groups by race.  RORs examined racial disparities. 

 

results: Rates and risks of fetal mortality increased with age.  Compared to NHWs, NHBs had a decreased risk of late fetal death for women aged <20 (aOR=0.67, 95% CI=0.63-0.71), but the risk was higher for 40+ women (aOR=1.96, 95% CI=1.77-2.17).  Disparities in the risk of fetal death between NHB and NHW increased, but the magnitude was not consistent across age groups (<20:  ROR=1.18, 95% CI=1.14-1.23 compared to 40+, ROR=3.77, 95% CI=3.4-4.1).    

conclusions: Racial disparities in fetal mortality persist and increase with age, but disparities between blacks and whites widened as maternal age increases.  Both age and race should be considered in the prevention and intervention related to fetal death.
