Objective:
To determine whether circumcision of HIV-positive men is associated
with increased subsequent sexual risk behaviors which may place their female
partners at risk.
Methods:
Newly circumcised and uncircumcised HIV-positive men in the Rakai
Community Cohort Study were followed from baseline (July 2013-January 2015)
to determine trend in sexual risk behaviors and association of circumcision
with subsequent sexual risk behaviors at follow up (February 2015-September
2016). Risk behaviors included sexual activity, alcohol before sex,
transactional sex, multiple sex partners, casual sex partners, and
inconsistent condom use with casual partners. The association was evaluated
using modified Poisson regression, and sensitivity analyses were performed
after multiple imputation with chained equations for missing data.
Results:
We identified 538 eligible men, of whom 113(21.0%) were circumcised
at baseline and 425(79.0%) were uncircumcised. Men in fishing communities
were more likely to be circumcised (p=0.032) as well as those exposed to
targeted HIV messaging (p<0.001). Overall, 188(34.9%) men were lost
to follow up and most were uncircumcised (p=0.020). Among those followed up,
behaviors remained largely unchanged with no differences by circumcision
status. Transactional sex appeared to be associated with circumcision in
unadjusted analyses (PR=1.58, 95%CI=1.01,2.48; p=0.045, p=0.05) and adjusted
analyses (adj.PR=1.54, 95%CI=1.06,2.23; p=0.022). However, the association
was no longer significant in sensitivity analyses after accounting for loss
to follow up (adj.PR=1.43, 95%CI=0.98,2.08; , p=0.066). No association with
circumcision was observed for other sexual risk behaviors.
Conclusion:
We found no association between circumcision of HIV-positive men and
subsequent sexual risk behavior.
