[BDSP. Notice produite par INIST-CNRS 8qttQR0x. Diffusion soumise à autorisation]. The burden of sexually transmitted diseases (STDs) is high in American Indian/Alaska Native (Al/AN) populations. In addition, race is often misclassified in surveillance data. This study examined potential racial misclassification of American Indians in STD surveillance data in Oklahoma. Oklahoma State STD surveillance data for 1995 were matched with the Oklahoma State Indian Health Service Patient Registry to determine the number of Al/AN women who had one of three STDs but were not listed in Oklahoma surveillance data as Al/AN. Accounting for racial misclassification increased the rate of chlamydia for Al/AN women in Oklahoma by 32% (342/100,000 vs. 452/100,000) in the overall population. For gonorrhea, the rate increased by 57% (94/100,000 vs. 148/100,000) and for syphilis by 27% (15/100,000 vs. 19/100,000). Misclassified Al/AN women most often were classified as "White," and the likelihood of misclassification increased with a lower percentage of Al/AN ancestry. These findings indicate that STD rates may be underestimated for Al/AN populations nationwide. Racial misclassification in state surveillance data causes inaccuracies in characterizing the burden of infectious diseases in minorities.
