The clinic serves an urban population. Two thirds of the study population were men and one third were women. Of the 32 HIV-seropositive clients, 29 (91%) were men and only 3 (9%) were women. Seroprevalence in men was higher than that in women, 4% vs 1%. The age distribution of HIV-positive clients (median age, 32 years) was older than that of the study population (median age, 27 years).
