Using multiple sampling approaches to measure sexual risk-taking among young people in Haiti: programmatic implications.

No previous published research has examined the applicability of varying methods for identifying young people who are at high risk of experiencing unintended pregnancy and acquiring HIV infection. This study compares three surveys of young people aged 15-24 in Port-au-Prince, Haiti, in terms of their sociodemographic characteristics and sexual behaviors and the surveys'usefulness for identifying young people at high risk and for program planning. The surveys consist of responses from: a representative sample of young people in the 2005-06 Haiti Demographic and Health Survey (HDHS), a 2004 facility-based study, and a 2006-07 venue-based study that used the Priorities for Local AIDS Control Efforts (PLACE) method.
