Increasing HIV prevalence among males who’ve intercourse with males in Nigeria: a trend analysis

Article metrics

Guys that have intercourse with guys (MSM) are conservatively predicted to be not as much as 1% associated with population that is nigerian nationally account fully for about 20per cent of brand new HIV illness. We estimated the trend in HIV prevalence and determined correlates of HIV disease among MSM.

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 similar methodology and hence enables contrast. Behavioral information were acquired utilizing an organized pre-coded questionnaire. Variations in categorical factors had been assessed with Chi Square. Logistic regression had been utilized to recognize facets connected with HIV.

An overall total of 879, 1545 and 3611 MSM had been recruited in 2007, 2010 and 2014 correspondingly. Median age had been 22 years for 2007 and 2014 whilst it had been 24 years this year. About one-third of MSM in 2007 and 2014 and about two-fifths this season had involved with transactional intercourse. HIV prevalence increased from 14% in 2007 to 17per cent this season to 23per cent in 2014 (p

Background

Globally, males who possess intercourse with guys (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 led to significant decreases in HIV among other sub-populations (basic populace, feminine intercourse employees), HIV among MSM has remained for a sustained increase globally 1, 3. The trend of HIV epidemic has been on a decline except among MSM 1 in high income countries. Likewise, available information on HIV incidence and prevalence from low and middle-income nations declare that the HIV epidemic among gay, bisexual along with other men that have intercourse with guys are on a markedly different and trajectory 1,2,3 that is increasing. In the united states, new HIV infections among MSM happens to be calculated to be increasing at 8% per year since 2001 1. When you look at the Amsterdam Cohort research among MSM, HIV acquisition increased from 1.0 per 100 person-years in 1992 to 2.0 per 100-person years during 2009 4, 5 while in China, from prospective cohort studies carried out among MSM between 2005 and 2007, HIV purchase had been reported to possess increased from 2.6 to 5.6 per 100 person-years 6,7,8,9.

Many studies of HIV purchase and transmission among MSM have actually mostly dedicated to individual degree risk factors including unprotected receptive rectal intercourse, large number of lifetime male lovers, inserting and non-injecting medication use and high viral load when you look at the index partner 1. Nonetheless, specific degree danger facets alone, have already been been shown to be inadequate to spell out the high transmission characteristics of HIV among MSM plus the divergence of MSM epidemics compared to HIV epidemics in other populations 1, 2. Other risk facets such as for example biological, couple-network degree, community-level and structural motorists have now been founded become relevant in knowing the persistent transmission that is high among MSM particularly in the clear presence of increased ART protection whereby brand brand new infections should decrease as a consequence of reduced odds of transmission due to the effectation of ART on viral load 2, 10, 11.

MSM in Nigeria are conservatively believed to be significantly less than 1% for the Nigerian population yet nationally account fully for about 20per cent of brand new HIV infections 12. MSM are criminalized and stigmatized and also this has further hot russian brides magazine worsened in modern times using the passage of the Same-Sex Marriage Prohibition law of 2014 13,14,15,16,17. The law that is new clauses that prohibited businesses from supplying solutions to MSM and facilitation of meetings that support homosexual people, thus further criminalizing same-sex activities 12. Research indicates why these restrictive policies further restrict the coverage that is poor of avoidance, therapy, and care programs among MSM 12, 18,19,20,21. Really few MSM-targeted HIV avoidance, therapy and care services occur in a small quantity of states in Nigeria. It is mainly due to restricted information in the size estimate of MSM across states along with restricted money for key population devoted programs. Information on MSM are mostly from three rounds for the Integrated that is population-based Biological Behavioural Surveillance Survey (IBBSS) conducted in, 2007, 2010, and 2014. This research aimed to evaluate the improvement in HIV prevalence and discover correlates of HIV among MSM in Nigeria. Proof with this scholarly research will likely to be utilized by policy manufacturer and system supervisors for evidence-based choice making for HIV prevention among MSM in Nigeria.

Study sites

In 2007, just three states – Lagos, Kano and Cross River, had been within the IBBSS. An additional three states were included in the IBBSS – the Federal Capital Territory (FCT), Kaduna and Oyo, while in 2014, Enugu and Rivers states were added to the six states included in the 2010 IBBSS in 2010, following increased awareness of the contribution of MSM to the HIV epidemic. Their state selection ensured that five associated with six zones that are geopolitical Nigeria had been represented into the study. Hence, the west that is southLagos and Oyo), south east (Enugu), south south (Rivers), north central (FCT) and north west zones (Kano and Kaduna) contributed into the research.
