Abstract
BACKGROUND: We aimed to determine associations between the mental health status of adolescents by self-reported sexual identity; and to determine associations between the mental health status of sexual minority adolescents living with and without HIV. METHODS: This cross-sectional study collected data from Nigerians aged 13-19 years old using an online survey. We collected information on dependent (sexual identity) and independent (presence of depressive symptoms, generalised anxiety disorder, suicidal attempt/ideation, HIV status) study variables. A multivariate regression model determined associations between the dependent and independent variables. A second multivariate regression model was developed to establish associations between HIV status among sexual minority individuals and the dependent variables. All models were adjusted for age, sex assigned at birth and education level. RESULTS: Among 1247 respondents living in Nigeria, 497 (39.9%) identified as sexual minority individuals. Compared with their heterosexual peers, sexual minority adolescents had significantly higher odds of reporting depressive symptoms (adjusted OR (AOR): 5.54; 95% CI: 4.10 to 7.47; p<0.001), high general anxiety (AOR: 3.56; 95% CI: 2.64 to 4.79; p<0.001) and history of suicidal attempt/ideation (AOR: 2.95; 95% CI: 2.20 to 3.94; p<0.001). Sexual minority adolescents living with HIV had significantly higher odds of high general anxiety (AOR: 2.42; 95% CI: 1.21 to 4.84; p=0.013), while those with unknown HIV status had significantly higher odds of depressive symptoms (AOR: 3.82, 95% CI: 2.78 to 5.27; p<0.001), high general anxiety (AOR: 3.09; 95% CI: 2.29 to 4.17; p<0.001) and suicidal attempt/ideation (AOR: 1.65; 95% CI: 1.22 to 2.24; p=0.001). CONCLUSION: Sexual minority adolescents reported poorer mental health status than heterosexual adolescents. Although there was no significant difference in the mental health status of sexual minority adolescents living and not living with HIV, sexual minority adolescents with unknown HIV status reported worse mental health than their HIV-negative peers. Sexual minority adolescents in Nigeria need comprehensive rights-based care that improves access to mental health services, and those with unknown HIV status may need both HIV and mental health screening and care.
