AB OBJECTIVES: To compare HIV-1 infection rates by reported number of
lifetime sexual partners in a rural cohort and an urban trading centre.
METHODS: A population cohort of 15 neighbouring rural villages in Masaka
District, SW Uganda has been kept under ethnodemographic, medical and
serological surveillance since 1989. HIV-1 serology and information on
numbers of lifetime sexual partners were obtained from 2704 adults (aged
13+ years) in the rural cohort. The same information was obtained from
389 adults in a cross-sectional study done in a near-by urban centre.
HIV-1 sero status was determined using 2 independent ELISA. RESULTS:
HIV-1 adult seroprevalence rates were 8% in the rural and 40% in the
urban population. Because of the weak association between HIV-1
infection rates and the number of reported lifetime sexual partner in
those aged 35 or more, the analysis has been restricted to those aged
13-34 years. Rates of infection in the urban centre were high for all
numbers of lifetime sexual partners and increased steeply in those
reporting 0 to 3 partners with no further increase thereafter. In
contrast, rates of infection in the rural cohort increased with
increasing number of partners to 10 or more (p < 0.001 for trend).
CONCLUSION: The results of this study show a strong association between
HIV-1 infection rates, the number of reported lifetime sexual partners
and back-ground HIV-1 prevalence rates. These results indicate that it
is possible to obtain meaningful data on sex history through population
surveys. TABULAR DATA, SEE ABSTRACT VOLUME.
