Background
Globally, the HIV
epidemic continues to represent a pressing public health issue in Europe and
elsewhere. There is an emerging and progressively urgent need to harmonise HIV
and STI behavioural surveillance among MSM across European countries through
the adoption of common indicators, as well as the development of trend analysis
in order to monitor the HIV-STI epidemic over time. The Sialon II project
protocols have been elaborated for the purpose of implementing a large-scale
bio-behavioural survey among MSM in Europe in line with a Second Generation
Surveillance System (SGSS) approach.
Methods/Design
Sialon II is a
multi-centre biological and behavioural cross-sectional survey carried out
across 13 European countries (Belgium, Bulgaria, Germany, Italy, Lithuania,
Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and the UK) in
community settings. A total of 4,966 MSM were enrolled in the study (3,661
participants in the TLS survey, 1,305 participants in the RDS survey). Three
distinct components are foreseen in the study protocols: first, a preliminary
formative research in each participating country. Second, collection of primary
data using two sampling methods designed specifically for ‘hard-to-reach’
populations, namely Time Location Sampling (TLS) and Respondent Driven Sampling
(RDS). Third, implementation of a targeted HIV/STI prevention campaign in the
broader context of the data collection.
Discussion
Through the
implementation of combined and targeted prevention complemented by meaningful
surveillance among MSM, Sialon II represents a unique opportunity to pilot a
bio-behavioural survey in community settings in line with the SGSS approach in
a large number of EU countries. Data generated through this survey will not
only provide a valuable snapshot of the HIV epidemic in MSM but will also offer
an important trend analysis of the epidemiology of HIV and other STIs over time
across Europe. Therefore, the Sialon II protocol and findings are likely to
contribute significantly to increasing the comparability of data in EU
countries through the use of common indicators and in contributing to the
development of effective public health strategies and policies in areas of high
need.
