Objective: To estimate parameters of concurrent sexual
partnerships in five urban populations in sub-Saharan Africa and
to assess their association with levels of HIV infection and other
sexually transmitted infections (STI). Methods: Data were obtained
from a multicentre study of factors which determine the
differences in rate of spread of HIV in five African cities.
Consenting participants were interviewed on sexual behaviour and
at four of the five sites also provided a blood and a urine sample
for testing for HIV and other STI. Data on sexual behaviour
included the number of partnerships in the 12 months preceding the
interview as well as the dates of the start and end of each
partnership. Summary indices of concurrent sexual partnerships -
some of which were taken from the literature, while others were
newly developed - were computed for each city and compared to HIV
and STI prevalence rates. Results: A total of 1819 adults aged
15-49 years were interviewed in Dakar (Senegal), 2116 in Cotonou
(Benin), 2089 in Yaounde (Cameroon), 1889 in Kisumu (Kenya) and
1730 in Ndola (Zambia). Prevalence rates of HIV infection were
3.4% for Cotonou, 5.9% for Yaounde, 25.9% for Kisumu and 28.4% for
Ndola, and around 1% for Dakar. The estimated fraction of sexual
partnerships that were concurrent at the time of interview (index
k) was relatively high in Yaounde (0.98), intermediate in Kisumu
(0.44) and Cotonou (0.33) and low in Ndola (0.26) and in Dakar
(0.18). An individual indicator of concurrency (iic) was developed
which depends neither on the number of partners nor on the length
of the partnerships and estimates the individual propensity to
keep (positive values) or to dissolve (negative values) on-going
partnership before engaging in another one. This measure iic did
not discriminate between cities with high HIV infection levels and
cities with low HIV infection levels. In addition, iic did not
differ significantly between HIV-infected and uninfected people in
the four cities where data on HIV status were collected.
Conclusion: We could not find evidence that concurrent sexual
partnerships were a major determinant of the rate of spread of HIV
in five cities in sub-Saharan Africa. HIV epidemics are the result
of many factors, behavioural as well as biological, of which
concurrent sexual partnerships are only one.
