Abstract
Background:
We compared factors associated with low HIV/AIDS knowledge among
internet-using MSM in
South Africa and the United States.
Methods:
1,154 MSM in the US and 439 MSM in South Africa, recruited through
Facebook.com,
completed an online survey using a US-validated HIV knowledge scale
(HIV-KQ-18). Separate
multivariable logistic regression models were built, one for the US
and one for South Africa, using a
dichotomized variable of scoring less than and equal to 13/18 ("low
knowledge") on the HIV-KQ-18 as
outcome.
Results:
Median knowledge scores were 16/18 for both groups of respondents.
For South African MSM,
factors associated with low knowledge were: a high school education
or less (adjusted odds ratio [aOR]:
2.5, 95% confidence interval [CI]: 1.4-4.6), not using
condom-compatible lubrication during last anal sex
with another man (aOR: 1.9, CI: 1.0-3.5), number of gay or bisexual
acquaintances (aOR: 0.89, CI: 0.81-
0.99), being unemployed (aOR: 2.2, CI: 1.0-4.6), and testing HIV
negative (aOR: 0.30, CI: 0.16-0.59) or
testing HIV positive (aOR: 0.15, CI: 0.03-0.74) compared to those
never HIV tested. For US MSM,
associated factors were: a high school education or less (aOR: 2.7,
CI: 1.9-3.8), low pride and acceptance
of homosexuality (aOR: 1.3, CI: 1.2-1.5), age 18-24 (aOR: 2.3, CI:
1.3-3.8) or age 50+ (aOR: 3.2, CI: 1.6-
6.3) compared to age 25-29, Hispanic ethnicity compared to white
non-Hispanic (aOR: 1.9, CI: 1.1-3.2),
and testing HIV positive (aOR: 0.34, CI: 0.16-0.69) or testing HIV
negative (aOR: 0.59, CI: 0.39-0.89)
compared to those tested.
Conclusions:
Those developing programs for MSM in South Africa should weigh
these data and other relevant
factors, and might consider focusing education services towards MSM
with limited education, less
integration into gay/bisexual communities, no HIV testing history,
limited use of condom-compatible
lube, and the unemployed. In the United States, Hispanic MSM, those
with limited education, no HIV
testing history, low pride/acceptance of homosexuality, and those
aged 18-24 or 50+ may be at risk for
gaps in HIV knowledge.
