The according to a study covering almost 8.3 million births in California.
Changes in severe maternal morbidity (SMM) prevalence from 1997 to 2014 were fairly consistent by race/ethnicity, although increases for black (179%), Asian/Pacific Islander (175%), and Hispanic (173%) women were somewhat larger than for whites (163%), Stephanie A. Leonard, PhD, of Stanford (Calif.) University, and her associates reported in Annals of Epidemiology.
Differences between races/ethnicities over the entire study period were seen for SMM with and without transfusion-only cases. Individual-level factors such as cesarean birth, comorbidities, and anemia “contribute to, but do not fully explain, these disparities. Additionally, changes in the characteristics of pregnant women – including increases in comorbidities – have not affected racial/ethnic differences in severe maternal morbidity over time,” the investigators wrote.
The cohort study used data for 8,252,025 live births with birth certificates that were previously linked to delivery discharge records. SMM was measured using the Severe Maternity Morbidity Index. Because “blood transfusion is the only qualifying indicator for approximately half of SMM cases … we also studied a subset of SMM that excluded those cases for which the only indication was a blood transfusion,” they noted.
