Central America 2013: TRaC study measuring sexual behaviors among People Living with HIV in Belize, Guatemala, El Salvador, Nicaragua, Costa Rica and Panama. Round 1.

1. GOAL OF THE TRaC STUDY The goal of this study is to collect baseline data on the prevalence of condom use and the opportunity, ability and motivation to adopt healthier behaviors among people living with HIV/AIDS (PLHA) in Central America. 2.

Control variables: socio-economic status, study sites, type of respondents (recruited through peers or clinics) and whichever variables that may determine exposure to interventions? Some of the main outcomes can also be control variables for other main outcomes. 2.2 Additionally, this study will provide the level of in key behavioral indicators (condom use at last sex and consistent condom use) among PLHA 2.3 And will help identifying which opportunity, ability and motivation constructs are significantly associated to safer behavior (condom use at last sex and consistent condom use
