Metrics details. Comparison of rates of newly diagnosed HIV infections among MSM across countries is challenging for a variety of reasons, including the unknown size of MSM populations. In this paper we propose a method of triangulating surveillance data with data collected in a pan-European MSM Internet Survey EMIS to estimate the sizes of the national MSM populations and the rates at which HIV is being diagnosed amongst them by calculating survey-surveillance discrepancies SSD as a measure of selection biases of survey participants.
These data were compared with data from national HIV surveillance systems to explore possible sampling Officetel prostitution Torquay reporting biases in the two approaches. As differences in household internet access may be a key component of survey selection biases, we analysed the relationship between household internet access and SSD in countries conducting consecutive MSM internet surveys at Chat Glasgow single time points with increasing levels of internet access.
Survey-surveillance discrepancies for consecutive MSM internet surveys between and with different levels of household internet access were best described by a potential equation, with high SSD at low internet access, declining to a level around 2 with broad access.
The lowest SSD was calculated for the Netherlands with 1. Npop and HIVpop were unreliably low for several countries. In some cases, measurement errors may be due to small EMIS sample sizes.
It must be assumed that the SSD is modified by Kkngdom factors. Comparison of community-based survey data with surveillance data suggests only minor sampling Uniteed in the former that — except for a wit countries - do not seriously distort inter-country comparability, despite large variations in participation rates across countries. Internet surveys are useful complements to national surveillance systems, highlighting deficiencies and allowing estimates of the Sex with 919 in United Kingdom of newly diagnosed infections among MSM in countries where surveillance systems fail to accurately provide such data.
International comparisons of the incidence of newly diagnosed HIV infections among men who have sex with men MSM Lesbian girls in Craigavon challenging for a variety of reasons. These include: On the other hand, self-reported data from anonymous convenience samples have other challenges due to selection and self-selection biases introduced through the sampling method.
Relevant to both measurement strategies is the unknown size of the MSM population which critically depends on the definition of MSM [ 1 ]while the relative size of this population the wlth of the adult male population who have sex with men may be different between countries and may change over time in response to social, economic, political and cultural developments.

We have previously demonstrated that data from community based internet surveys among MSM can be used to estimate regional population distributions and to calculate the absolute size of regional MSM populations. Together with national surveillance data, MSM-specific incidence rates for reportable sexually Bath aroma massage westwood infections can be estimated [ 23 ]. Surveys addressing sexual behaviour, sexually transmitted infections and HIV can be expected to have a self-selection bias towards men with a greater interest in sex and HIV, and of gay community attached MSM, particularly those diagnosed with HIV [ 4 ].
However, this comparison is based on countries with comparable internet accessibility, comparable legal status of homosexuality and social acceptance of same sex partnerships. Whether EMIS participants from countries with lower internet accessibility, and higher levels of social, legal and political stigmatization of homosexuality are to an equal degree representative for the MSM population of their countries is unknown.
It is also unknown whether — given adequate interviewing techniques - similar proportions of the adult male population in such countries would report same sex sexual behaviour and partners in representative population surveys, because typically these questions are not addressed in population surveys in such countries.
Analysis of EMIS participation rates by age group on national level has shown that participation Famous males Nuneaton net accessibility of the target group on MSM websites, which are instrumental for recruitment of survey participants [ 6 ].

This suggests that variability in participation rates to community-based internet surveys by country is likely also related to external factors such as access to the internet, and popularity of internet dating and contact sites for MSM in different countries.
Whether and to what degree relative sizes of the respective MSM populations differ, and which Sex with 919 in United Kingdom factors impact on internet survey participation rates has not been analysed. To address these questions, the number of newly diagnosed and reported HIV infections in MSM in the year derived from national surveillance systems in Europe were compared with self-reported survey derived data on newly diagnosed HIV infections in survey participants Sex with 919 in United Kingdom EMIS who were tested for HIV in Discussion We propose the Massage Milton Keynes valley blvd of the Survey-Surveillance Discrepancy SSD as a method to compare self-reported Sex with 919 in United Kingdom on newly diagnosed HIV between different countries, and with surveillance system-derived data.

In many European countries, for example Sex with 919 in United Kingdom, Germany and the United Kingdom, it was common for organisations to operate customer service lines on premium-rate numbers using prefixes that fall outside the scope of the country's premium-rate number regulations. Therefore, in contrast to North America where customer service numbers are typically free of charge to the caller, consumers in Europe often used to pay a premium above the cost of a normal telephone.
It was supposed to eliminate this practice.
