Prevalence and temporal trends of hepatitis B, hepatitis C, and HIV/AIDS co-infection during pregnancy across the decade, 1998-2007.
BACKGROUND
Limited data are available on hepatitis rates during pregnancy by socio-demographic characteristics. This study examined temporal trends in hepatitis B virus (HBV) and hepatitis C virus (HCV) mono-infections and HIV/HBV and HIV/HCV co-infections in subpopulations among pregnant women in Florida between 1998 and 2007.


METHODS
We analyzed all Florida live births from 1998 to 2007 using hospital discharge data linked to birth records.


RESULTS
The total sample size was 1,700,734 singleton live births. The prevalance of HBV in pregnancy rose from 65.4 per 100,000 births to 123.5 per 100,000 births (p<0.0001 for trend), and the prevalence of HCV in pregnancy increased from 17.0 per 100,000 births to 125.1 per 100,000 births (p<0.0001 for trend). Compared with white mothers, black mothers were more than twice as likely to have HBV in pregnancy (adjusted rate ratios [ARR]=2.24; 95% CI=1.97-2.53). Black mothers were 69% (ARR=0.31, 95% CI=0.25-0.39) and Hispanic mothers were 51% (ARR=0.49, 95% CI=0.41-0.60) less likely to have HCV compared with white mothers.


CONCLUSIONS
Although the overall prevalence rate of HBV increased over the past decade, black women still had a noticeably higher rate of infection. Similarly, white women and those with HIV co-infection had noticeably higher rates of HCV infection over the study period. Our findings call for improved and increased HBV/HCV prevention, screening, and immunization programs among minority women of childbearing age.
