The survey included 598 adolescents (14-17 years old) who responded questions on bullying, sociodemographic characteristics, health-risk behaviors, educational well-being, family structure, physical activity, markers of nutritional habits, and subjective well-being (body image, personal satisfaction, and satisfaction with their present and future life).

The paradigm of universal access to HIV-treatment and human rights violation: how do we treat HIV-positive people who use drugs?

HIV-positive people who use drugs (PWUDs) are particularly vulnerable for suboptimal access to highly active antiretroviral therapy (HAART). We conducted a systematic review to identify factors associated with suboptimal HAART access among this population. Studies evaluating HAART access among active PWUDs as a primary outcome, presenting multivariate analysis and conducted after January 1997 were included.
