In the urban groups aged 15–24, prevalence declined by 47% (23.4% to 12.4%, P < 0.001) among females and 57.3% (7.5% to 3.2%, P = 0.001) among males but were 32% and 27% in men and women aged 15–49, respectively. In age-group 15–49 years, declines were less than 25%.
Saliva was used for HIV testing, and refusal was <10%. Absence, <30% in men and <15% in women in all rounds, was the most important cause of non-response. Multivariate logistic regression and trend analyses were stratified by residence, sex and age group. Population-based HIV surveys in 1995 (n = 3158), 1999 (n = 3731) and 2003 (n = 4751) were conducted in selected communities using probability proportional to size stratified random-cluster sampling. We examined HIV prevalence patterns in selected communities of men and women aged 15–59 years in Zambia. Understanding the epidemiological HIV context is critical in building effective setting-specific preventive strategies.
