Prison environment and non-communicable chronic disease modifiable risk factors: length of incarceration trend analysis in Mexico City.

Background: There is a lack of evidence regarding chronic disease modifiable risk factors among prisoner populations in Latin America. The purpose of this study was to estimate the prevalence of modifiable risk factors for chronic diseases and to assess their relationship with length of incarceration.

Methods: We analysed data from a cross sectional study in which 4241 prisoners were randomly selected to answer a questionnaire with socio-demographic and health behaviour content using an audio computer-assisted self-interview format.

Objective: Whilst existing data suggests that the HIV epidemic in Ecuador is concentrated amongst men who have sex with men (MSM), there is very little available information on the situation of key populations, i.e. those most at risk of HIV infection and/or transmitting the infection.
