The Challenges and Opportunities for Mental Health Twin Research in Nigeria.

The recent interest in increasing diversity in genetic research can be useful in uncovering novel insights into the genetic architecture of mental health disorders - globally and in previously unexplored settings such as low- and middle-income settings like Nigeria. Genetic research into mental health is potentially promising in Nigeria and we reflect on the challenges and opportunities for twin research which may be particularly suited to Nigeria. The higher rates of twinning in Africa and Nigeria specifically, make the twin design an affordable and readily maintainable approach for genetic research in the country. Despite potential challenges with recruitment, data collection, data analysis and dissemination; the success of current efforts suggest that the twin design can tapped even further for greater impact in the country. We highlight some ways in which the scope of twin research can be increased and suggest some ways in which existing challenges can be overcome including recent Patient Participant Involve and Engagement activities.

Antiretroviral therapy non-adherence and its association with psychosocial factors in Nigeria: comparative study of sexual minority and heterosexual men living with HIV.

Sexual minority men (gay, bisexual and other men who have sex with men; SMM) in Nigeria are disproportionately affected by HIV compared to heterosexual men. There is a dearth of research on the correlates of antiretroviral therapy (ART) non-adherence and correlates in both groups. The current study examined the associations of ART non-adherence with sociodemographic and psychosocial characteristics among a sample of Nigerian heterosexual and SMM. Between March and September 2014, we surveyed 120 SMM and 108 heterosexual men receiving ART in Lagos and Abuja, Nigeria. We specified univariate and multivariable linear regression models to examine correlates of ART non-adherence. We found that 50.8% and 29.6% of sexual minority and heterosexual men respectively self-reported ART non-adherence which was significantly associated with psychosocial factors such as stigma, depressive symptoms, and suicidality. Mental health care and psychosocial support should be incorporated into routine HIV care for Nigerian SMM living with HIV.
