Contribution of Population Factors to Estimation of Human Immunodeficiency Virus Prevalence Trends: A Cohort Study in Rural Uganda, 1989-2007
American Journal of Epidemiology
Because the incidence of human immunodeficiency virus (HIV) infection is difficult to measure directly, prevalence trends often serve to track epidemiologic changes. Adult HIV prevalence in open population cohort studies, however, reflects changes in incidence, population factors (migration, deaths, and aging), and survey coverage. Data from an open cohort in rural Uganda enabled estimation of the contribution of these factors to prevalence trends from 1989 to 2007.
