people whose rights are not respected on the basis of their gender identity or sexual orientation lack protection within families and the community at large . this places a constraint on their ability to seek health services and information . at the same time , for economic reasons or due to low self - esteem , they may engage in risky behavior which can predispose them to infection with human immunodeficiency virus ( hiv ) and hepatitis virus . the lack of opportunities for people experiencing social exclusion pushes them toward financial poverty , worsens their physical and mental health status , and perpetuates this vicious cycle.1 according to research conducted by anthropologists , pockets of areas existed in africa before the colonial era where homosexuality was practiced . it was not openly acknowledged because issues related to sexuality were taboo and not intended for public discussion.2 open acknowledgment of same sex relationships is perceived as a threat to the traditional african culture and religion because it contradicts their definition of what constitutes family and community . it is also perceived to be the negative influence of westernization ( globalization ) and should therefore be repressed or curtailed . several actions are undertaken to achieve this , including bullying , taunting , hostility , discrimination , and violence.3 stigma , discrimination , and human rights violation has trailed the hiv epidemic and had posed a significant challenge hampering efforts geared toward prevention , care , and support . from the report of a survey conducted between 2008 and 2011,4 a high proportion of men and women living with hiv in nigeria reported verbal and physical abuse , experiencing stigma within the family and community , as well as loss of job or income.5 achieving universal access will remain a dream if people most at risk , infected , or affected can not access information and services . this can be as a result of punitive laws , economic circumstances , religious beliefs , sociocultural prejudices , and norms that pose structural barriers.4 human rights violations , including extrajudicial killings , torture , detention , and even rape , have been perpetuated against individuals on the basis of their sexual orientation and gender identity . to protect the human rights of individuals with respect to this issue , a set of guidelines , ie , the yogyakarta principles , were developed to guide the application of international human rights.6 as of may 2013 , most of the un member countries were not conforming to the yogyakarta principles ; 65 countries and 85 entities have anti - discriminatory laws compared with the 31 countries and 35 entities that recognize same sex unions . same sex activities and relationships in the northern sharia - implementing states of nigeria , somalia , and another five countries in the world attract the death penalty . in 71 countries and five entities , the punishment is imprisonment.1,7 according to chapter 21 articles 214 and 217 of the country s criminal code , same - sex sexual activity is a felony in nigeria , and punishable by imprisonment of up to 14 years.1,6,7 greater experiences of family rejection , a traumatic form of emotional abuse as a result of gender identity and sexual orientation , has been linked with poor mental health outcomes ( attempted suicide , high levels of depression , and substance use problems among adolescents).8 one of the recognized coping mechanisms seen upon exposure to a stressful environment is alcohol and drug use aimed at numbing the pain experienced . this can lead to alcohol dependency and drug abuse , creating a situation whereby men will engage in risky sexual behavior . globally , the number of new hiv infections and acquired immune deficiency syndrome ( aids)-related deaths has been dropping over the years . an estimated 20% reduction in the number of people newly infected with hiv and 24% fewer deaths from the disease was observed between 2001 and 2011.5 in nigeria , available reports indicate an increase in the number of people newly infected with hiv from an estimated 250,000 in 2005 to over 388,000 in 2012 . men who have sex with men ( msm ) and their partners , according to the report , were responsible for 10% of all new infections that occurred in the country within that time period.9 globally , the prevalence of hiv has been observed to be higher among msm than in the general population in most countries.5 in nigeria , 17.2% of msm were living with hiv in 2010 compared with the national prevalence of 4.1%.10 this study examined the occurrence of human rights violations among msm living in lagos in 2012 before the same sex marriage prohibition bill was signed into law by the president of the federal republic of nigeria . the study site was lagos , a densely populated cosmopolitan city in south western nigeria . a list of community centers frequented by msm in lagos state was collected from the lagos state aids control agency . only seven of the 20 local government areas ( lgas ) in the state had community centers for msm . their activities are sponsored by partners and donor agencies through grants , provision of behavioral communication materials , training , and capacity development of staff . msm go there to access services through referrals and by one - on - one introduction . activities are carried out indoors ; there are no banners or signpost advertising the venue or its activities . it is a close - knit setting ; some of the staff manning the centers are females , but only msm can access services at these centers . three of the seven lgas were selected through simple random sampling ; each of the selected lgas had only one community center , so all three were used . advocacy visits were subsequently conducted to the three community centers , and the stakeholders and networks manning the centers were duly briefed on the study and its purpose . the benefit of the study was also highlighted , and verbal informed consent was given by the authorities manning the three centers . participants recruited for the study were men over 18 years of age who had had sexual relationships with members of the same sex and visited the community center for recreational activities or hiv prevention information and services between 9 am and 6 pm from monday to saturday in august 2012 . heterosexuals who visited the community centers for whatever reason during the period of data collection were excluded from participation by staff and peers . only msm who agreed to participate in the study participation was voluntary and participants were assured that all information supplied would be anonymous and kept in a confidential manner . the formula for calculating sample size in a cross - sectional descriptive study was used based on the proportion of msm reporting risky sexual behavior in the 2010 integrated biological and behavioural surveillance survey ( 25.5%).10 the significance level was set at 0.05 and a calculated minimum sample size of 291 was obtained , which was increased by 10% to 320 to allow for nonresponse . the snowball sampling method was used to recruit 107 participants from each of the centers . the msm operating the centers were recruited as the initial seeds , and were then asked to recruit peers who visit the centers . these next groups of respondents were similarly asked to identify peers , and this went on until the desired sample size was attained . none of the respondents received any form of incentive or reimbursement for participation in this research . three research assistants were recruited , trained , and paid a stipend to assist in the distribution and collection of the questionnaires in the field . ethical approval was obtained from the lagos university teaching hospital health research and ethics committee ( reference adm / dcst / hrec / vol . a semistructured pretested questionnaire was used to collect information on demographics , alcohol and drug use , hiv risk behavior , and experience of human rights violations . aggression was described as unprovoked attacks , confrontation , and violent behavior as a result of sexual orientation . alienation was described as a perceived feeling of isolation by family or friends from activities which they would have normally been involved in . the data analysis was done using statistical package for the social sciences version 20 software ( ibm corporation , armonk , ny , usa ) and presented as means and percentages . only 291 questionnaires were analyzed because some of the respondents did not complete all items in the questionnaire . bivariate analysis was performed to test the relationship between dependent and independent variables at p<0.05 . a logistic regression model was used to assess the relationship between the outcome variables , namely acts of aggression and sexual and physical abuse , and sociodemographic variables that were statistically significant on bivariate analysis with a 95% confidence interval and p<0.05 . three of the seven lgas were selected through simple random sampling ; each of the selected lgas had only one community center , so all three were used . advocacy visits were subsequently conducted to the three community centers

sociodemographic variables that were statistically significant on bivariate analysis with a 95% confidence interval and p<0.05 . the study participants had a mean (  standard deviation ) age of 25.34.6 years , close to two thirds ( 59.1% ) had at least a secondary school education , and 29.9% had post - secondary education . two thirds ( 66.0% ) of the men were currently single and not in a steady relationship , while 19.6% were cohabiting or in a steady relationship and only 12.0% were married . regarding sexual orientation / identity , 50.5% self - reported as gay , 47.8% as bisexual , and 1.7% as transgender ( table 1 ) . alcohol use was quite common , with 56.7% of the msm consuming alcohol ; in this group , more than half ( 57.6% ) reported drinking alcohol to the point of intoxication . only 11.1% of the men reported using hard drugs , ie , marijuana , amphetamines , and cocaine , and none reported using more than one type of hard drug or injecting drugs ( table 1 ) . recreational activities include visiting hotspots ( reported by 43.6% ) , partying ( 38.8% ) , clubbing ( 35.7% ) , watching movies ( 35.7% ) , and surfing the internet ( 39.2% ) ; 29.9% of the men sought sexual partners at the community center , 21.0% from hotels / brothels , 39.5% at parties , 39.9% when they visited private homes , and 48.1% from bars / clubs . one third ( 33.0% ) had disclosed that they had same sex relationships to either a family member / friend or both . homosexual / transgender respondents were more likely to have made such a disclosure than bisexual respondents ( 51.3% versus 15.8% ; p<0.001 , see table 1 ) . about a third of the men reported at least one act of human rights violation , ranging from aggression 35.7% , alienation 29.9% , discrimination in the workplace 8.2% , eviction 2.1% , or refusal of service 4.1% . another 20.3% reported at least one incident of violence , including rape by a man 16.8% , verbal abuse 19.2% , physical abuse 17.9% , and psychological abuse 20.3% ( table 2 ) . on bivariate analysis , a higher proportion of msm who were single and not in a steady relationship were found to report acts of aggression compared with those who were married / in a steady relationship ( p=0.003 ) . . a higher proportion of young msm ( < 30 years ) and men with a low level of education reported experiencing acts of aggression , respectively ( p=0.020 and p=0.029 ; table 3 ) . homosexuals were more likely to report experiences of social oppression , ranging from acts of aggression ( p=0.002 ) to physical ( p=0.036 ) and sexual ( p=0.044 ) violence . disclosure of sexual orientation was associated with acts of aggression ( p<0.001 ) and physical abuse ( p<0.001 ) . alcohol consumption was associated with reports of physical ( p=0.020 ) and sexual ( p=0.001 ) violence . a higher proportion of msm who solicited for sexual partners from brothels , clubs , and community centers reported instances of aggression ( p=0.003 , p=0.014 , and p=0.003 , respectively ) . the relationship between age and reported acts of aggression was not maintained in multivariate analysis . msm with less than a secondary school education were twice as likely to report acts of aggression ( adjusted odds ratio [ aor ] 2.6 ; p=0.019 ) . homosexual / transgender respondents were also twice as likely to report acts of aggression ( aor 1.9 ; p=0.017 ) , as were unmarried msm not in a steady relationship ( aor 2.3 , p=0.005 ) . men who consumed alcohol were three times as likely to report sexual abuse ( aor 3.4 ; p=0.001 ) and twice as likely to report physical abuse ( aor 2.3 ; p=0.013 ) . homosexual / transgender men were twice as likely to report sexual ( aor 2.2 ; p=0.021 ) and physical abuse ( aor 2.1 ; p=0.022 ) . the respondents in this study were mostly young men under the age of 30 years with a fair level of education for a low income country . it has been observed that young msm are especially vulnerable in this era of hiv infection.11 decreasing or stable rates of infection have not been achieved in this group . globally , less than 10% of msm are estimated to have access to hiv prevention services at an individual level , within a social context , within communities , or from health service providers.12 further , a high prevalence of hiv infection was recorded among people less than 30 years of age in the 2010 national seroprevalence study conducted among the general population in nigeria.9 bisexuality has been found to be common among african msm . the proportion of the young people in this study who described themselves as bisexual is much higher than the 17% recorded in cape town.13 bisexuality was described as an adaptation to escape the social stigma associated with gender orientation or identity by msm in senegal.14 alcohol consumption was more common than tobacco use or substance abuse , and like the study conducted among msm in northern thailand , alcohol use and substance abuse was not significantly associated with sexual orientation.15 in african countries where same sex relationships have been criminalized or where msm experience social stigma , more and more msm are turning to the internet to meet their peers as well as to solicit for sexual partners.16 studies carried out in various african countries have reported human rights violations among msm . in cape town , almost a quarter of respondents in one study had been subjected to either blackmail , physical / sexual abuse , or denial of services.13 in lesotho , about three quarters of msm in a study reported having experienced beatings , rape , blackmail , or harassment as a result of their sexual orientation.17 respondents in a multicountry study carried out in malawi , namibia , and botswana mentioned violence as a threat to their life as msm , with more than 40% having been raped by men , beaten up , blackmailed , or denied health care.16 experiences of msm in this study with regard to this issue were similar , although sexual orientation was a predictor of social oppression . social stigma puts msm at greater risk of developing mental health problems , thereby adding to the disease burden . in most sub - saharan african countries , the expression of masculinity is that men should be strong and not display signs of weakness or vulnerability . this leads to poor health - seeking behavior by men , resulting in a low turnout for preventive , curative , and rehabilitative care until disease has progressed or complications arise resulting in premature death.18 an hiv prevention , care , and treatment program carried out in senegal between 2004 and 2007 was able to achieve a reduction in individual risk - taking behavior ( unprotected sex ) among msm . this can only be carried out in an environment free of violence , blackmail , and acts of discrimination . with the criminalization of same sex relationships in the same country , there was a substantial reduction in the provision of services by health workers and the uptake of these services . the majority of the targeted group went into hiding as a result of increased violence and discrimination.14 similarly , a high proportion of msm in other african countries reported being afraid to seek health care services because they had been victims of blackmail on the basis of their sexual orientation.19 bisexual men in hiding will not access services from community centers and networks linked to msm because of fear of exposure . at the same time , they are not adequately catered for in national programs , which focus more on women and children . they are therefore at the risk of being missed , excluded , or side - lined.19 recruitment of msm occurred at a community center which is most probably frequented by msm from a particular network / lga . access to the study population would have been extremely difficult if the researchers did not actively engage the management team of the centers . the msm operating the centers were the ones recruiting their peers into the study , which could have introduced some degree of selection and response bias . a nonprobability sampling method was used to recruit participants for the study , even though the lgas where the centers were located were selected using a simple random sampling method . this study was carried out among a subset of the key population in need of intervention in the hiv epidemic , and reveals that msm in lagos state have been victims of various acts of human rights violation and abuse . there is an urgent need to document and quantify these happenings in all the states of the federation . it will also be necessary to investigate how human rights violations of msm in nigeria impacts on access to hiv care and prevention of transmission .
backgroundin several african countries , men who have sex with men ( msm ) are becoming visible , as a result of which they are now victims of human rights violations . 
 this has a negative effect on their ability to access services targeted at human immunodeficiency virus ( hiv ) prevention and care . 
 the main objective of this study was to document the experiences of social oppression among msm in lagos state , nigeria.methodssimple random sampling was used to select three of the seven local government areas in lagos state that had community centers . 
 snowball sampling was used to recruit 291 participants . 
 the survey instrument was a pretested questionnaire . 
 the results were presented as means and percentages . 
 univariate , bivariate , and multivariate analysis was carried out at p<0.05.resultsthe mean age of the participants was 25.34.6 years , and the majority ( 66.0% ) were currently single and not in a steady relationship . 
 half of the men self - identified as gay and about 48% as bisexual . 
 alcohol use occurred in 56.7% of the respondents , about a quarter ( 25.8% ) smoked cigarettes , and 11.0% reported using hard drugs . 
 the commonest acts of human rights violation and or violence reported were aggression 35.7% , alienation 29.9% , verbal abuse 19.2% , physical abuse 17.9% , rape by a man 16.8% , and psychological abuse 20.3% . 
 the predictors of human rights violation were level of education ( adjusted odds ratio 2.6 , p=0.019 ) , marital status ( adjusted odds ratio 2.3 , p=0.005 ) , and sexual orientation ( adjusted odds ratio 1.9 , p=0.017 ) . for physical and sexual abuse , msm who consumed alcohol and were 
 homosexual / transgender were at risk.conclusionthis study showed that a high proportion of msm had experienced various forms of human rights violation and abuse as a result of their sexual orientation / identity . 
 there is a need to document and quantify these happenings , which can serve as an advocacy tool for reform .
