Objectives:We examined trends in maternal comorbidities in California.
Methods: We conducted a retrospective cohort study of 1 551 017 California
births using state-linked vital statistics and hospital discharge cohort data for
1999, 2002, and 2005. We used International Classification of Diseases, Ninth
Revision, Clinical Modification codes to identify the following conditions, some
of which were preexisting: maternal hypertension, diabetes, asthma, thyroid
disorders, obesity, mental health conditions, substance abuse, and tobacco use.
We estimated prevalence rates with hierarchical logistic regression models,
adjusting for demographic shifts, and also examined racial/ethnic disparities.
Results: The prevalence of these comorbidities increased over time for
hospital admissions associated with childbirth, suggesting that pregnant
women are getting sicker. Racial/ethnic disparities were also significant. In
2005, maternal hypertension affected more than 10% of all births to non-Hispanic
Black mothers; maternal diabetes affected nearly 10% of births to Asian/Pacific
Islander mothers (10% and 43% increases, respectively, since 1999). Chronic
hypertension, diabetes, obesity, mental health conditions, and tobacco use
among Native American women showed the largest increases.
Conclusions:The prevalence of maternal comorbidities before and during
pregnancy has risen substantially in California and demonstrates racial/ethnic
disparity independent of demographic shifts. |
