Research Question
• Do individuals who learn that MC reduces female-tomale HIV transmission also infer a reduction in direct
male-to-female HIV risk (i.e. from an HIV-positive man
to an uninfected woman)?
• Individuals were asked about the number of women (out of 100) who
would contract HIV after sleeping with a circumcised or uncircumcised
HIV+ man.
• Similar questions were asked about the risk of contracting HIV for
circumcised versus uncircumcised men with an HIV+ woman.
Study design

1224 men
interviewed
Random
assignment
2009
Control
468 re-interviewed
Intervention
484 re-interviewed
1-on-1 discussion:
MC & Male HIV risk
+
431 Women
interviewed (wives
of male sample)
Key Findings
• 72% of men and 82% of women who believed that MC reduces a man’s
risk of HIV infection also believed that MC directly reduces a woman’s
HIV risk.
• On average, the greater the extent to which MC was believed to reduce
HIV risk for men, the greater the extent to which MC was believed to
reduce HIV risk for women:
Key Findings
• 50% of men who were randomized to information that MC reduces a
man’s risk of HIV infection (intervention) believed that MC reduces HIV
risk for women compared to 38% in the control group.
• The belief that MC directly reduces HIV infection risk for women
appeared to be driven by beliefs that MC protects men:
Implications
• Results add to emerging evidence of beliefs that MC protects women held in
different regions of southern Africa.
• These beliefs may decrease the ability of women to negotiate condom use with
circumcised partners.
• An explanation for evidence of risk compensatory behaviours among women?
• Individuals may actively project the messages of information campaigns to
groups that do not actually benefit from a particular intervention or change in
behaviour.
• VMMC information campaigns should explicitly state that MC has not been
shown to offer any direct HIV protective benefits for women.
• Caveat: Be careful not to confuse messages about MC and male HIV infection risk.
• Further research: Understand the consequences of such incorrect beliefs.
