This study monitored long-term temporal trends in HIV-1 prevalence in antenatal clinic attendees living in western Uganda. Semi-annual data collection was done from 1991 to 2004. For each woman the following data were recorded: HIV-1 status, age, educational status, marital status, occupation and parity. The results show that the overall HIV-1 prevalence was 15.3% during the entire time period (urban 21.3%, semi-urban 12.7% and rural 7.1%). Between 1991 and 2004, we observed a gradual decline in the HIV-1 prevalence. The decline was most pronounced in urban women aged 15–19 years old and least pronounced in rural women aged 20–24 years. Women above 25 years of age did not show any decline in HIV-1 prevalence over time. The declining HIV-1 prevalence in the younger age groups (15–24 years) likely represents a declining risk for acquiring HIV infection as we have previously shown in the urban sub-sample of this data set.
