RESUMEN
OBJECTIVE: This systematic review aims to synthesize articles, abstracts and reports of HIV prevalence studies conducted among men who have sex with men (MSM) and female sex workers (FSW) in Latin America and the Caribbean (LAC). MATERIALS AND METHODS: Authors searched online databases and collected gray literature on HIV prevalence among MSM and FSW from LAC. Year, location, sampling methodology, study design, sample size, HIV prevalence and confidence intervals were abstracted. RESULTS: A total of 73 studies, dating from 1986 to 2010 were included.The median prevalences for MSM and FSW were 10.6% (interquartile range: 7.4- 17.4) and 2.6% (IQR: 0.6 -4.2), respectively. Variability was high, especially for MSM. The majority of studies recruited participants using convenience methods. CONCLUSION: HIV prevalence among MSM was higher than that among FSW. Sampling techniques should be standardized for future studies, prioritizing probability methods.

OBJETIVO: Esta revisión sistemática tiene el objetivo de sintetizar artículos, resúmenes y reportes de estudios de prevalencia de VIH en hombres que tienen sexo con hombres (HSH) y mujeres trabajadoras sexuales (MTS) en América Latina y el Caribe (ALC). MATERIAL Y MÉTODOS: Se realizaron búsquedas en bases de datos electrónicas y se recopiló literatura gris sobre la prevalencia de VIH en HSH y MTS de América Latina y el Caribe. Los datos recolectados fueron año, lugar, metodología de muestreo, diseño del estudio, tamaño muestral, prevalencia de VIH e intervalos de confianza. RESULTADOS: Se incluyó un total de 73 estudios, realizados de 1986 a 2010. La mediana de la prevalencia para HSH y MTS fue 10.6% (rango intercuartil: 7.4- 17.4) y 2.6% (RIC: 0.6-4.2), respectivamente. La variabilidad de las prevalencias estimadas fue alta, especialmente para HSH. La mayoría de estudios usaron muestras por conveniencia. CONCLUSIONES: La prevalencia de VIH entre HSH es superior a MTS. Los métodos muestrales deben ser estandarizados para estudios futuros, priorizando métodos probabilísticos.
