Abstract

Background The protective effect of hormonal contraception may offer a potential intervention against bacterial vaginosis (BV). Study Design Three hundred thirty reproductive-age women enrolled in a contraceptive program from April 2005 to October 2006 at two sexually transmitted diseases clinics in Baltimore, MD. Participants were supplied with hormonal contraceptives of their choice and followed prospectively. BV was diagnosed by Amsel's criteria. Results from population-level analysis were compared to a case-crossover analysis. Results BV was diagnosed in 189 (13.0%) of the visits among 133 (40.3%) women. In the population-level analysis, the use of progestin-only and combined contraception was associated with a decreased risk of BV compared to intervals of no hormonal contraceptive use [adjusted odds ratio (AOR): 0.42 (95% CI: 0.20–0.88) and AOR: 0.66 (95% CI: 0.39–1.10), respectively]. The case-crossover analysis demonstrated a similar trend in findings. Conclusion Hormonal contraception was associated with a decreased risk of BV in an STD clinic cohort.

Abstract

Objective: Identify factors associated with false-positive rapid HIV antibody tests. Design: This retrospective cohort study with nested case–controls involved patients tested for HIV by Boston Medical Center (BMC) affiliates. Methods: Cases had a reactive fingerstick OraQuick ADVANCE rapid HIV 1/2 antibody test and a negative Western blot. Controls had nonreactive rapid tests. We compared the prevalence of HIV risk factors between cases and the total nonreactive population and the prevalence of other clinical factors between cases and controls. Results: Of the 15 094 tests, 14 937 (98.9%) were negative and 11 (0.07%) were false positives (specificity of 99.9%). Cases were more likely to have had an HIV-infected sex partner and to be tested at certain sites compared to true negatives. More cases than controls had O-negative blood type. Conclusion: O-negative blood type and sex with an HIV-infected person may increase false-positive HIV fingerstick results. More targeted studies should examine these risk factors.
