2003 JUL 3 - (NewsRx.com & NewsRx.net) -- U.S. Centers for Disease Control and Prevention researchers conducted a study of the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), and herpes simplex-2 (HSV-2) virus infections among a representative sample of the U.S. population ages 20-59.
They wanted to see if race and/or ethnic differences in the group remained significant risk factors for acquiring these sexually transmitted diseases "after stratification and multivariate adjustment for risk behaviors."
G. McQuillan and colleagues tested sera from approximately 10,000 adult participants examined in NHANES III (1988-1994) for antibody to HBV (anti-HBc), HCV, and HSV-2.
They reported that "overall, multivariate modeling for all significant cofactors (compared to age adjustment alone) almost always reduced the odds of seropositivity for both non-Hispanic blacks (NH blacks) and Mexican Americans (MA) [as compared to non-Hispanic whites (NH-whites)].
"Analysis within high and low risk behavior strata demonstrated that the effect of race/ethnicity was often greatest among those with the lowest risk. For HBV, the odds ratio for NH blacks was 6.7 (95% CI: 3.3, 13.5) in the low risk group and 2.8 (95% CI: 2.0-3.9) in the high risk group," McQuillan reported at the 36th Annual Society of ...
