Depression and suicidal behavior in LGB and heterosexual populations in Serbia and their differences: Cross-sectional study

Abstract

Background: Sexual identity is a significant risk factor for triggering symptoms of depression, as well as for suicide attempts in lesbian, gay and bisexual (LGB) population compared to the heterosexual population. To the best of our knowledge, data on the mental health of LGB persons in Serbia are lacking, and this is the first study to address this problem. The aim of the study was to examine the association between selected determinants and depression, and selected determinants and suicide attempts in LGB and heterosexual populations in the Republic of Serbia, as well as, their differences.

Methods: We conducted a cross-sectional study in 2015 of 264 heterosexual and LGB respondents using the "snowball sampling" method. We used linear regression analyses to investigate the relationship between socio-demographic variables and different sexual identity categories with PHQ-9 scores. We assessed associations between suicide attempts, and socio-demographic characteristics, sexual identity, depression, and suicidal thoughts using logistic regression.

Results: Depression symptoms were higher in female relative to male participants, in participants who were single, divorced or widowed in comparison to currently married, among people with a middle level of education compared to highly educated, and in respondents identified as bisexual or homosexual in comparison to heterosexual. Homosexual and bisexual participants reported suicidal attempts 27 [Odds Ratio (OR) = 27.31] and six times (OR = 6.40) more often than did heterosexual respondents, respectively. Suicide attempts were less frequently reported by single, divorced or widowed participants in comparison to married (OR = 0.25) and those with middle education (OR = 0.38) compared to highly educated.

Conclusions: The present study showed that LGB persons in Serbia have significantly more symptoms of depression and suicide attempts compared to heterosexuals. Public health interventions should focus on the early detection of depression and on overcoming prejudicial and discriminatory attitudes. Also, intervention should emphasize that homosexuality and bisexuality are normal, equal and morally acceptable expressions of human sexuality.
