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. Physical activity (PA), low-quality diet, current smoking and alcohol or cocaine use during the last month in prison were our main outcomes. Quantile regression models and logistic regression models were performed. RESULTS: Our final analytical sample consisted of 3774 prisoners from four Mexico City prisons. PA was estimated as 579 median metabolic equivalents-min/week, prevalence of alcohol use was 23.4%, cocaine use was 24.2% and current smoking was 53.2%. Our results suggest that, as length of incarceration increased, PA as well as alcohol and cocaine use increased, whereas the quality of diet decreased. CONCLUSION: This study supports the hypothesis that exposure to prison environment (measured by length of incarceration) fosters modifiable risk factors for chronic diseases, particularly diet quality and cocaine use.

[Inconsistent condom use among sexual workers in Ecuador: results from a behavior survey]. / Uso inconsistente del condón entre trabajadoras sexuales en ecuador: resultados de una encuesta de comportamientos.

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. In particular, there is very little known about sex workers (SWs), their rate of condom use and other behaviors and characteristics with respect to the risk of acquiring sexually transmitted infections (STIs). This study presents findings from a survey carried out with SWs in eight cities in Ecuador. MATERIAL AND METHODS: Using a cross-sectional design, a questionnaire focusing on behaviours, attitudes and socio-economic and demographic characteristics was administered to SWs in eight cities in Ecuador. These eight cities together account for the majority of the population in the country, and they were also identified as the locations with high reported levels of HIV. RESULTS: Information from a total of 2867 SWs was obtained, the majority were captured in their workplaces. Most of SWs interviewed carry out their activities in closed settings dedicated to sex work (i.e. not in the street). The average age of respondents was 28 (95%CI 27-29), and around half of them live with a male partner (married or not). The rate of condom use with the last client was 88% (82% consistently with the last three), whilst with regular partners it was 6%. A high index of life-skills, high socio-economic status and having an official document that allows them to work, were positively associated with condom use with clients (PR [CI95%] 1.40 [1.40-1.40], 1.37 [1.36-1.37], y 7.26 [6.87-7.46], respectively). CONCLUSIONS: Whilst condom use with clients amongst Ecuadorian SWs is high, this diminishes if one analyzes consistent condom use and is notably low with respect to regular partners. Condom use appears to be related to variables that can be linked to interventions, e.g. life-skills and official permission to carry out sex work. It is, therefore, important to tailor interventions for this population so they maximize the likelihood to increase consistent condom use.

Uso inconsistente del condón entre trabajadoras sexuales en Ecuador: resultados de una encuesta de comportamientos / Inconsistent condom use among sexual workers in Ecuador: results from a behavior survey

OBJETIVO: Obtener información sobre la tasa de uso del condón y otros comportamientos y características relacionados con el riesgo de adquirir infecciones de transmisión sexual en trabajadoras sexuales (TS) de ocho ciudades del Ecuador. Este estudio presenta resultados de una encuesta realizada con TS en ocho ciudades del Ecuador. MATERIAL Y MÉTODOS: Se trata de un estudio transversal en el que se aplicó un cuestionario de comportamientos, actitudes y características socioeconómicas y demográficas a una muestra de TS en las ocho ciudades del Ecuador que concentran a la mayor parte de la población del país y padecen la mayor problemática en relación con el VIH. RESULTADOS: Se obtuvo información de un total de 2 867 TS, la mayor parte de ellas en sus lugares de trabajo. El mayor porcentaje de las TS entrevistadas realizaba sus actividades en sitios dedicados al comercio sexual. La edad media de las entrevistadas fue de 28 años (IC95 por ciento 27-29) y alrededor de la mitad vivía con parejas masculinas (ya sea casadas o en unión libre). La tasa de uso del condón con el último cliente fue de 88 por ciento (82 por ciento de forma consistente); en cambio, con las parejas regulares fue de 6 por ciento. Un alto índice de habilidades para la vida, mayor nivel socioeconómico y contar con permiso para trabajar se relacionaron de forma positiva con el uso del condón con clientes (RP= 1.40; IC95 por ciento 1.40-1.40; RP= 1.37; IC95 por ciento 1.36-1.37; y RP= 7.26; IC95 por ciento 6.87-7.46, respectivamente). CONCLUSIONES: Si bien el uso del condón de las TS ecuatorianas con clientes es elevado, disminuye si se analiza su consistencia y es sumamente bajo cuando se trata de parejas regulares. La utilización del condón, por otra parte, parece relacionarse con variables sobre las cuales es posible realizar intervenciones para modificarlas, como las habilidades para la vida y el permiso oficial para realizar el trabajo sexual. En ese sentido, es importante realizar intervenciones específicas que incrementen el uso consistente del condón en esta población.
