This research utilized information from respondent-driven sampling in three rounds of built-in biological and behavioral surveillance study (2007, 2010 and 2014) and covered three states in 2007, six states this season and eight states in 2014. Each round utilized methodology that is similar hence enables contrast. Behavioral information were acquired making use of a organized questionnaire that is pre-coded. Variations in categorical factors had been evaluated with Chi Square. Logistic regression ended up being utilized to spot facets related to HIV.
A complete of 879, 1545 and 3611 MSM were recruited in 2007, 2010 and 2014 correspondingly. Median age had been 22 years for 2007 and 2014 although it had been 24 years this season. About one-third of MSM in 2007 and 2014 and about two-fifths this season had involved in transactional intercourse.

Globally, males that have intercourse with males (MSM) remain disproportionately infected and affected by HIV 1, 2. Despite huge opportunities in worldwide HIV and expanded treatment that is antiretroviralART) programs which have lead to significant decreases in HIV among other sub-populations (basic populace, feminine intercourse employees), HIV among MSM has remained on a sustained increase globally 1, 3.

Many studies of HIV purchase and transmission among MSM have actually mostly focused on specific degree risk factors including unprotected receptive rectal intercourse, lot of lifetime male lovers, inserting and non-injecting medication usage and high viral load within the index partner 1. However, specific level danger facets alone, have now been proved to be insufficient to describe the high transmission characteristics of HIV among MSM while the divergence of MSM epidemics in comparison to HIV epidemics in other populations 1, 2. Other danger facets such as for example biological, couple-network degree, community-level and structural motorists have already been founded become pertinent in comprehending the persistent transmission that is high among MSM specially in the current presence of increased ART protection whereby brand brand new infections should decrease because of reduced possibility of transmission due to the effectation of ART on viral load 2, 10, 11.
MSM in Nigeria are conservatively believed to be not as much as 1% of this Nigerian population yet nationally account fully for about 20per cent of brand new HIV infections 12.

This season, after increased understanding of the contribution of MSM towards the HIV epidemic, yet another three states were contained in the IBBSS – the Federal Capital Territory (FCT), Kaduna and Oyo, whilst in 2014, Enugu and streams states had been put into the six states contained in the 2010 IBBSS. Their state selection ensured that five associated with the six zones that are geopolitical Nigeria had been represented when you look at the study. Therefore, the the west (Lagos and Oyo), south east (Enugu), south south (streams), north central (FCT) and north west areas (Kano and Kaduna) contributed to your research.
Sampling design and recruitment
Each round for the IBBSS utilized respondent sampling that is driven to your concealed nature of MSM and so enables contrast between and across rounds. Respondent sampling that is drivenRDS) was described at length in previous studies 22, 23. Fleetingly, RDS is really a modified chain referral non-random sampling technique of recruitment that adjusts for the non-randomness utilizing a mathematical model that loads each sample recruited 23. Inclusion criteria had been male aged 16 years and above with a brief history of dental and/or anal contact that is sexual another guy when you look at the half a year before the survey.

Ten seeds had been chosen for every circular and seeds had been diversified by age, academic status and socioeconomic status. To prevent an over-representation of MSM with comparable attributes, vouchers limited by three per recruit was utilized 23, 24. In addition, in order to prevent perform enrollment, just one screener ended up being used, only 1 individual ended up being authorized to reimburse MSM that has effectively recruited their peers and just one location had been utilized. Each voucher had been yielded and redeemable N500 approx. $3 USD being a motivation for participating, with one more N500 directed at a recruit for every single effective extra participant. Total settlement ended up being restricted to a compensation that is maximum of approximately $12 USD. Test size for the 2007 IBBSS had been calculated centered on a thought HIV prevalence of 15%, a design effectation of 2.0 and amount of accuracy of 0.05. For the 2010 and 2014 IBBSS, test size ended up being projected to identify a 10% vary from the round that is subsequent.
