Abstract

MINGOTI, Sueli Aparecida; CAIAFFA, Waleska Teixeira  and  PROJETO AJUDE-BRASIL II. A capture-recapture technique to estimate the size of the injecting drug user population attending syringe exchange programs: AjUDE-Brasil II Project. Cad. Saúde Pública [online]. 2006, vol.22, n.4, pp. 783-789. ISSN 0102-311X.  http://dx.doi.org/10.1590/S0102-311X2006000400017.

This paper presents the results of a study with a two-occasion capture-recapture design. The data are part of the AjUDE-Brasil II Project, carried out in 2000-2001. Estimation of the size of the IDU population attending a syringe-exchange program (SEP) in São José do Rio Preto, Salvador, and Porto Alegre, Brazil, was performed using Chao's model. Capture probabilities were also estimated. For Porto Alegre a comparison of the results from the AjUDE-Brasil I and AjUDE-Brasil II Projects was performed. Results are also presented for error rates secondary to the choice of matching criteria.

Keywords : Harm Reduction; Intravenous Susbtance Abuse; Street Drugs; Syringe-Exchange Programs.
